Fear and avoidance of shoulder movement according to the International Code of Functioning: cross-sectional study / Medo e evitação de movimento do ombro segundo o Código Internacional de Funcionalidade: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Shoulder pain is a limiting condition that has a major impact on daily activities and work. Knowing which specific activities involving the shoulder are associated with the occurrence of higher levels of pain may be of interest to professionals. The use of images of shoulder movements can be an effective tool to check the presence of pain and fear of movement, break down language and cultural barriers, and facilitate communication between professional and patient. The objectives of this study were: (1) to carry out a descriptive analysis of fear responses and movement avoidance based on passive viewing of images of shoulder movements based on the International Classification of Functioning, Disability and Health (ICF) codes; (2) to check whether there is a correlation between fear responses and movement avoidance with the Shoulder Pain and Disability Index (SPADI). METHODS: In this cross-sectional observational study, individuals with chronic shoulder pain were recruited. Participants responded to the Shoulder Pain and Disability Index (SPADI) and the TAMPA Scale of Kinesiophobia (TSK) to measure the intensity of shoulder pain and disability, and fear of movement, respectively. Participants viewed 58 movement images based on codes and descriptors from the third chapter of ICF. In addition, they responded to a numerical scale to judge fear of movement and a second numerical scale to judge movement avoidance. RESULTS: The study included 42 individuals. The activities belonging to the mobility subgroup (chapter 4), which refers to chapter 3 of the ICF, are those that present greater responses of fear and movement avoidance. Multiple regression resulted in a significant model [F(1, 40) = 31.119; p<0.001; R2 = 0.438], when verifying whether fear and movement avoidance responses related to ICF images are associated with SPADI in participants with chronic shoulder pain. The fear response is associated with SPADI (β=0.661; t=5.578; p<0.001), however, the avoidance response did not present a significant result with the scale (β=−0.063; t=-0.160; p=0.874). CONCLUSION: Movements that refer to mobility seem to be the most feared and avoided by people with chronic shoulder pain. Fear of movement is associated with shoulder disability.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor no ombro é uma condição limitante, que apresenta grande impacto nas atividades de vida diárias e no trabalho. Conhecer quais atividades específicas envolvendo o ombro estão associadas à ocorrência de maiores níveis de dor pode ser de interesse dos profissionais. A utilização de imagens de movimentos do ombro pode ser uma ferramenta eficaz para verificar a presença de dor e medo de movimento, quebrar barreiras de linguagem e culturais e facilitar a comunicação entre profissional e paciente. Os objetivos deste estudo foram: (1) realizar a análise descritiva das respostas de medo e evitação do movimento a partir da visualização passiva de imagens de movimentos do ombro baseadas nos códigos da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF); (2) verificar se há correlação das respostas de medo e evitação do movimento com o Índice de dor e Incapacidade do Ombro (SPADI). METODOS: Neste estudo observacional do tipo transversal foram recrutadas pessoas com dor crônica no ombro. Os participantes responderam ao Shoulder Pain and Disability Index (SPADI) e à Escala TAMPA de Cinesiofobia (TSK) para mensurar a intensidade da dor e incapacidade do ombro, e de medo do movimento, respectivamente. Os participantes visualizaram 58 imagens de movimentos baseadas em códigos e descritores do terceiro capítulo de Atividade e Participação da CIF. Além disso, responderam a uma escala numérica para julgar o medo do movimento e a uma segunda escala numérica para julgar a evitação ao movimento. RESULTADOS: Participaram do estudo 42 pessoas. As atividades pertencentes ao subgrupo mobilidade (capítulo 4), referente ao capítulo 3 da CIF, são as que apresentam maiores respostas de medo e evitação do movimento. A regressão múltipla resultou em um modelo significativo [F (1, 40) = 31, 119; p<0,001; R2 = 0,438], ao verificar se as respostas de medo e evitação do movimento referente às imagens da CIF estão associadas ao SPADI dos participantes com dor crônica no ombro. A resposta de medo é associada ao SPADI (β=0,661; t=5,578; p<0,001), porém a resposta de evitação não apresentou resultado significativo com a escala (β=−0,063; t=−0,160; p=0,874). CONCLUSÃO: Os movimentos que se referem à mobilidade parecem ser os mais temidos e evitados por pessoas com dor crônica no ombro. O medo do movimento está associado com a incapacidade do ombro.

Dry needling in the treatment of myofascial trigger points and painful shoulder dysfunctions: narrative review of the literature / Agulhamento a seco no tratamento de pontos-gatilho miofasciais e disfunções dolorosas do ombro: revisão narrativa da literatura

ABSTRACT BACKGROUND AND OBJECTIVES: Shoulder painful dysfunctions comprises one of the most common musculoskeletal disorders that requires specialized assistance. Dry Needling (DN) became an adjuvant approach with increased use in clinical practice to treat this type of condition. The present study discusses the literature related to DN in the treatment of myofascial trigger points (MTPs), shoulder dysfunctions and associated pain. METHODS: A narrative review through search of articles from 2010 to 2022 written in Portuguese, English or Spanish was performed in Latin American and Caribbean Literature on Health Sciences (LILACS), Health Information from the National Library of Medicine (Medline), Web of Science and the Scientific Electronic Library Online (Scielo) databases using the keywords: <"Dry Needling">; <"Agulhamento a Seco">; <"Myofascial Trigger Points">; <"Pontos-Gatilhos Miofasciais">; <"Shoulder Dysfunctions">; <"Disfunções do ombro">. The qualitative analysis was performed determining the level of evidence for DN treatment of MTPs, shoulder dysfunctions and pain. RESULTS: A total of 45 citations were found, 22 citations were excluded because they did not meet the selection criteria. The 23 remaining citations were examined for titles and abstracts and duplicate studies were removed. Finally, 10 articles met the selection criteria and were included in the present review. No articles were excluded after full-text screening. The analysis showed poor advances and knowledge regarding the application of DN for the treatment of pain, painful and general shoulder dysfunctions and MTPs, with few evidence regarding treatment effectiveness, patient's pain scores data, mechanisms of action and statistical analysis. CONCLUSION: There is still a lack of concrete scientific evidence to assess DN effectiveness in modulating pain in patients with MTPs shoulder. More systematic reviews and meta-analyses together with experimental and clinical searches must be conducted to provide stronger evidence of this modality to relief painful symptoms in the shoulder, as well as a treatment of MTPs and general shoulder disorders.

RESUMO JUSTIFICATIVA E OBJETIVOS: As disfunções dolorosas de ombro constituem uma das disfunções musculoesqueléticas mais comuns que requerem assistência especializada. O agulhamento a seco (AS) tornou-se uma abordagem adjuvante com uso crescente na prática clínica para tratar esse tipo de condição. O objetivo deste estudo foi rever na literatura aspectos relacionados ao AS no tratamento de pontos-gatilho miofasciais (PGMs), disfunções do ombro e dores associadas. MÉTODOS: Foi realizada uma revisão narrativa através da busca de artigos de 2010 a 2022 escritos em português, inglês ou espanhol, na Literatura Latino-Americana e do Caribe nos bancos de dado Ciências da Saúde (LILACS), Informações em Saúde da Biblioteca Nacional de Medicina (Medline), Web of Science e Scientific Electronic Library Online (Scielo) utilizando as palavras-chave <"Dry Needling">; <"Agulhamento a Seco">; <"Myofascial Trigger Points">; <"Pontos-Gatilhos Miofasciais">; <" Disfunções do ombro">. A análise qualitativa foi realizada determinando o nível de evidência para tratamento de AS para o tratamento de PGMs, disfunções do ombro e dor. RESULTADOS: Um total de 45 citações foram encontradas, 22 citações foram excluídas porque não atenderam aos critérios de seleção. As 23 citações restantes foram examinadas para títulos e resumos e estudos duplicados foram removidos. Finalmente, 10 artigos atenderam aos critérios de seleção e foram incluídos na presente revisão. Nenhum artigo foi excluído após a triagem de texto completo. A análise mostrou poucos avanço e conhecimento sobre a aplicação de AS para o tratamento da dor, disfunções dolorosas e gerais do ombro e PGMs, com poucas evidências sobre a eficácia do tratamento, dados dos escores de dor do paciente, mecanismos de ação e análise estatística. CONCLUSÃO: Ainda faltam evidências científicas concretas para avaliar a eficácia do AS na modulação da dor em pacientes com PGMs no ombro. Mais revisões sistemáticas e meta-análises associadas a pesquisas experimentais e clínicas devem ser realizadas para fornecer evidências dessa modalidade promissora para alívio de sintomas dolorosos no ombro, bem como tratamento de PGMs e distúrbios gerais do ombro.

Facilitators and barriers for adherence of shoulder pain patients to a home-based exercise program: cross-sectional study / Facilitadores e barreiras para a adesão de pacientes com dor no ombro a um programa de exercícios domiciliares: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Home-based exercises can improve function and quality of life in shoulder pain patients. Knowing the facilitators and barriers is crucial for adherence to shoulder pain treatment. It is believed that individuals who adhere to home exercises have fewer environmental barriers, pain intensity and shoulder disability. The aim of this study is to identify facilitators and barriers for adherence to a home-based exercise program in shoulder pain individuals, and to investigate the influence of environmental barriers, shoulder pain and disability, and kinesiophobia on adherence to a program. METHODS: This is a cross-sectional study. Shoulder pain individuals performed home-based exercises for eight weeks based on a booklet in addition to supervised physical therapy or as their sole therapy. They reported the perceived facilitators and barriers to home exercises adherence and answered the Craig Hospital Inventory of Environmental Factors (CHIEF), Shoulder Pain and Disability Index (SPADI), and the Tampa Scale for Kinesiophobia (TSK) questionnaires. Logistic regression models analyzed the scores of the CHIEF, SPADI, and TSK as predictors of adherence. RESULTS: Fifty individuals participated in this study and 88% adhered to the program. The most frequent facilitator and barrier were "having guidance from a professional," and "lack of available time," respectively. Pain and disability were the only predictor of adherence (p=0.044), and an increase of one point in SPADI reduced the likelihood of adherence to home exercises by 14% (Exp(B) =0.86). CONCLUSION: Individuals reported facilitators and barriers to the exercise program. Environmental barriers assessed using the CHIEF and kinesiophobia were not predictors of adherence.

RESUMO JUSTIFICATIVA E OBJETIVOS: Os exercícios domiciliares podem melhorar a função e a qualidade de vida de pacientes com dor no ombro. Conhecer facilitadores e barreiras é fundamental para adesão ao tratamento da dor no ombro. Acredita-se que indivíduos que aderem aos exercícios domiciliares apresentem poucas barreiras ambientais, baixa intensidade de dor e incapacidade do ombro. O objetivo deste estudo foi identificar facilitadores e barreiras para a adesão a um programa de exercícios domiciliares em indivíduos com dor no ombro e investigar a influência de barreiras ambientais, da dor e incapacidade no ombro, e da cinesiofobia na adesão ao programa. MÉTODOS: Neste estudo transversal, indivíduos com dor no ombro realizaram exercícios domiciliares por oito semanas com base em uma cartilha além da fisioterapia supervisionada ou como sua única terapia. Os indivíduos relataram facilitadores e barreiras percebidos para a adesão aos exercícios em casa e responderam ao Craig Hospital Inventory of Environmental Factors-Brasil (CHIEF-Br), Shoulder Pain and Disability Index-Brasil (SPADI-Br) e Escala Tampa de Cinesiofobia (TAMPA). Os escores do CHIEF-Br, SPADI-Br e TAMPA foram analisados como preditores de adesão por meio de modelos de regressão logística. RESULTADOS: Participaram do estudo 50 indivíduos e 88% aderiram ao programa. O facilitador e a barreira mais frequentes foram "receber orientação de um profissional" e "falta de tempo disponível", respectivamente. Dor e incapacidade foram os únicos preditores de adesão (p=0,044), e o aumento de um ponto no SPADI-Br reduziu a probabilidade de adesão aos exercícios domiciliares em 14% (Exp(B) =0,86). CONCLUSÃO: Os indivíduos relataram facilitadores e barreiras ao programa de exercícios. A barreiras ambientais avaliadas por meio do CHIEF-Br e a cinesiofobia não foram preditores da adesão.

Analysis of misdiagnosed cases of neck, shoulder, waist and leg pain caused by bone metastases and early warning measures / 中国基层医药

Objective:To investigate the cause of misdiagnosis of neck, shoulder, waist, and leg pain caused by bone metastases and to improve the outpatient diagnosis rate.Methods:Five misdiagnosed cases of bone metastases who were admitted to the Traditional Chinese Medicine Department of Orthopedics and Traumatology, School of Traditional Chinese Medicine, Southern Medical University from January 2019 to July 2020 were included in this study. Their clinical manifestations, diagnosis results (outside hospital diagnosis and outpatient diagnosis), and imaging manifestations were retrospectively analyzed.Results:Five cases of bone metastases were misdiagnosed to have cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain. Accelerated red blood cell sedimentation rate and increased C-reactive protein level were found in all five cases. Bone metastases were confirmed by X-ray, CT, and MRI examination results. All of them had warning signs for bone metastasis: age > 50 years, history of a tumor, unexplained weight loss, general malaise, neck, shoulder, waist, and leg pain without an obvious cause, sudden worsening of pain, night pain, resting pain, pain on direct palpation, no obvious improvements in these symptoms after symptomatic treatment for 1 month, disease development not conforming to the general law of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, increases in red blood cell sedimentation rate, C-reactive protein, and alkaline phosphatase levels, which are not consistent with the symptoms of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, and slight external force leading to fractures.Conclusion:Further tests and imaging examinations should be performed according to warning signs. Clinical schemes of malignant bone tumors suitable for general practitioners can easily, economically, and effectively identify malignant bone tumors.

Reverse Shoulder Arthroplasty: Evaluation of the Clinical and Functional Outcomes per Etiology / Artroplastia reversa de ombro: Avaliação dos resultados clínicos e funcionais de acordo com a etiologia

Abstract Objective The present study aimed to evaluate the clinical outcomes of reverse shoulder arthroplasty to treat several conditions. Methods Retrospective, longitudinal study analyzing the Constant and University of California at Los Angeles (UCLA) scores and range of motion of patients undergoing reverse shoulder arthroplasty. Results In total, 28 patients were analyzed, with a mean age of 75.6 years old. The mean duration of follow-up was 45 months. Overall, there was a significant variation (p< 0.0001) between the preoperative (10.2 points) and the postoperative UCLA scores (29.6 points), corresponding to a relative increase of approximately 200%. In addition, the mean Constant score was 67.8, and the complication rate was 17.8%. As for functional outcomes per etiology, fracture sequelae cases presented the best mean elevation (165°), Constant score (79 points), postoperative UCLA score (32.5 points), and absolute delta UCLA score increase (22 points), but with no statistical significance. However, cases operated for fracture sequelae showed significantly higher elevation (p= 0.027) and Constant score (p= 0.047) compared to rotator cuff arthropathy cases. In addition, the lowest mean postoperative Constant and UCLA scores were observed for the following etiologies: primary arthrosis, acute fracture, and arthroplasty revision. Conclusion Reverse shoulder arthroplasty showed satisfactory functional outcomes and may be a treatment option not only for rotator cuff arthropathy but for several other conditions.

Resumo Objetivo Avaliar os resultados clínicos da artroplastia reversa do ombro no tratamento de suas diversas indicações. Métodos Estudo longitudinal retrospectivo que analisou os resultados dos escores Constant, UCLA e amplitudes de movimentos dos pacientes submetidos à artroplastia reversa do ombro. Resultados Foram analisados 28 pacientes, a média de idade foi de 75.6 anos, com seguimento médio de 45 meses. No geral, obtivemos uma variação significativa (p< 0,0001) entre o escore UCLA pré-operatório (10,2 pontos) e o escore UCLA pós-operatório (29,6 pontos), o que corresponde a um aumento relativo de aproximadamente 200%. Além disso, obtivemos pontuação média do escore Constant de 67,8 e uma taxa de complicações de 17,8%. Quanto aos resultados funcionais segundo as indicações, os casos de sequela de fratura apresentaram as melhores médias de elevação (165°), escore Constant (79 pontos), escore UCLA pós-operatório (32,5 pontos) e aumento absoluto na variação do escore UCLA (22 pontos), sem significância estatística. Porém, identificou-se que os casos operados por sequela de fratura apresentaram elevação (p= 0,027) e pontuação no escore Constant (p= 0,047) significativamente maiores em relação aos casos de artropatia do manguito rotador. Além disso, observamos que as menores médias dos escores Constant e UCLA pós-operatórios foram obtidos nas seguintes etiologias: artrose primária, fratura aguda e revisão de artroplastia. Conclusão A artroplastia reversa de ombro apresentou resultados funcionais satisfatórios, podendo ser uma opção de tratamento não somente nos casos de artropatia do manguito rotador, mas também em várias outras patologias.

Upper extremities functional disability and pain intensity in female volleyball athletes: cross-sectional study / Incapacidade funcional de membro superior e intensidade de dor em atletas de voleibol do sexo feminino: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: In volleyball, the high demand for shoulder sports makes it susceptible to injuries due to the repetition of sporting gestures. The presence of pain in the shoulder can lead to the disability to perform movements correctly, resulting in reduced sports performance. The study aimed to evaluate and correlate the presence of pain and functional disability of the upper extremity in volleyball athletes. METHODS: Cross-sectional descriptive study, developed with 30 female volleyball athletes. Functional disability was assessed using the Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) and pain intensity using the Visual Numeric Scale (VNS). The study was conducted in an online format. The IBM SPSS 21.0 statistical package for Windows was used, where descriptive measures, Wilcoxon, and Spearman correlation tests were performed, adopting p≤0.05. RESULTS: Nineteen athletes reported mild to moderate pain to perform daily activities, and 21 athletes reported pain to perform sporting gestures, with pain being significantly more intense in the dominant shoulder in the spike movement (p<0.001), serve (p<0.001), and blocking (p=0.03). Athletes did not present functional limitations in the DASH, but the opposite, outside hitter, and middle blocker, presented mild limitations in the DASH sport. There was a strong correlation between DASH and day-to-day pain (rs=0.79; p<0.001) and a moderate correlation between sports DASH and pain in the dominant shoulder in the spike (rs=0.67; p<0.001) and in the serve (rs=0.60; p<0.001) movements. CONCLUSION: Evaluated athletes presented shoulder pain, higher functional disability to performer the sports activity, and pain and functional disability were positively correlated HIGHLIGHTS Overhead movements such as serve and spike contribute to shoulder pain in volleyball players; The functional disability of the upper limbs is positively correlated with the intensity of pain to perform daily activities and sports; The kinetic-functional diagnosis is important to minimize the risk of injury, rehabilitate injured athletes and provide an adequate return of the athlete to sports practice.

RESUMO JUSTIFICATIVA E OBJETIVOS: No voleibol, a alta exigência da articulação do ombro torna-o suscetível a lesões devido à repetição dos gestos esportivos. A presença de dor no ombro pode gerar incapacidade para executar os movimentos corretamente, ocasionando redução do desempenho esportivo. O estudo teve como objetivo avaliar e correlacionar a presença de dor e incapacidade funcional de membro superior em atletas de voleibol. METODOS: Estudo transversal, descritivo, desenvolvido com 30 mulheres atletas de voleibol de quadra. A incapacidade funcional foi avaliada por meio do Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) e a intensidade de dor pela Escala Visual Numérica (EVN) de 10 pontos. A pesquisa foi conduzida no formato on-line. Utilizou-se o programa estatístico IBM SPSS 21.0 para Windows, pelo qual foram realizadas as medidas descritivas, o teste de Wilcoxon e a correlação de Spearman adotando p≤0,05.

As atletas não apresentaram limitação funcional no DASH geral, mas no DASH esporte as opostas, ponteiras e centrais foram classificadas com limitação leve. Houve correlação forte entre DASH e dor no dia a dia (rs=0,79; p<0,001) e correlação moderada entre DASH esporte e dor no ombro dominante no ataque (rs=0,67; p<0,001) e no saque (rs=0,60; p<0,001). CONCLUSAO: Atletas avaliadas apresentaram dor no ombro, maior incapacidade funcional na atividade esportiva, e dor e incapacidade funcional estavam positivamente correlacionadas. DESTAQUES Movimentos aéreos como saque e ataque contribuem para a dor no ombro em jogadores de voleibol; A incapacidade funcional dos membros superiores correlaciona-se positivamente com a intensidade da dor para a realização de atividades cotidianas e esportivas; O diagnóstico cinético-funcional é importante para minimizar o risco de lesão, reabilitar atletas lesionados e proporcionar um retorno adequado do atleta à prática esportiva.

Comparison between the isokinetics parameters of shoulder joint and independence functional level in manual wheelchair users / Comparação entre parâmetros isocinéticos da articulação do ombro com nível de independência funcional em usuários de cadeira de rodas manual

Shoulder pain is a common complaint in the wheelchair user's population. This condition brings loss of independence and quality of life. Objective: The aim of this paper is to correlate shoulder joint isokinetic parameters and independence level of manual wheelchair users with or without pain. We hypothesize that users more independent are exposed to overuse injury of shoulder joints. Method: This is an explorative cross-sectional study with a quantitative approach. Community patients attended at a Rehabilitation Center. Manual wheelchair users. Twenty-four patients participated, we used the Functional Independence Measurement (FIM) to investigate the independent level of wheeled patients and isokinetic parameters of internal/external rotators and flexion/extension muscles of shoulder joint was collected using Biodex System 4 Pro. Statistical analyses were made by Fisher Test, Spiro-Wilk Test, Pearson Correlation test, Spearman test and the Coefficient of correlation's value was squared to estimate the percentage of variation in dependent variable, explained by independent variable. Results: Total FIM variation was between 79 and 117 and median ipsilateral strength ratio of rotator muscles were 0.94 on 75°/s and 0.95 on 150°/s for the right limb and respectively 0.96 and 0.93 for the left limb. Conclusion: Wheelchair users present internal/external rotators shoulder muscles imbalance and the covariations samples of time of injury and peak torque ratio external/internal shoulder rotators have a significant predictive value on total MIF. These results suggest that there is correlation between the studied patients and shoulder impairment.

Prevalence of Pain Conditions in Type 2 Diabetes Mellitus patient: A Cross Sectional Study

Background: Type-2 Diabetes mellitus (T2DM) is a metabolic disease characterized by hyperglycemia and may causes long term organs dysfunctions like retinopathy, nephropathy, neuropathy, cardiovascular and autonomic dysfunction. Musculoskeletal and nervous system can also be affected by T2DM resulting pain, dysfunctions and disabilities. Objectives: This study is to find the prevalence of different pain conditions in patients with T2DM.Material & Methods:The study was conducted in public and private hospitals of four cities (Brahmanbaria, Dhaka, Gazipur and Faridpur) of Bangladesh from 1st April to 31st September, 2021. The patients of type II diabetes mellitus with both gender and age above 40 were included, and patients with other active systemic disease of bones and soft tissues were excluded. A self-structured questionnaire was developed. The questionnaire was distributed among 500 patients, out of whom 450 patients responded. The non-probability convenient sampling technique was used for data collection. The data was analyzed by SPSS and percentages were calculated to estimate the musculoskeletal complications in patients with T2DM.Results:The result showed high prevalence of pain conditions in T2DM patients. Older age groups of 61-65 (24%) years suffering from T2DM for more than 3 years having higher bloodsugar level 17-19 mmol/L with positive family history of DM were affected mostly. The prevalence of musculoskeletal pain condition in T2DM was 71.11%, while the low back pain was (42.88%), frozen shoulder was 31.33%, diabetic neuropathy was (26.89%) were the most common musculoskeletal problems, followed by knee pain (17.33%). Conclusions:It is concluded that the prevalence of different pain conditions are high among patients of T2DM and low back pain, shoulder pain, peripheral neuropathy and knee pain are common. These are mostly manageable conservatively.

Scapulothoracic Bursitis or the Snapping Scapula Syndrome May Mimic with Shoulder Pain

Background: The scapulothorasic joint plays an important role in overall shoulder function by providing a stable base for glenohumeral rotation. Snapping scapula syndrome, a likely under diagnosed condition, can produce significant shoulder dysfunction in many patients. Because the precise origin is difficult to understand, sometimes mimic with shoulder pain. Dysfunctioning of any of muscles, ligament, bursa may cause abnormal scapular motion and predispose to scapulothoracic joint disorders. Accurate recognition of the syndrome may lead to prompt and long-term relief of symptoms by conservative or noninvesiveintervension treatment.Results:The causes of scapulothoracic bursitis and crepitus include direct or indirect trauma, overuse syndromes, glenohumeral joint dysfunction, boney abnormalities, muscle microtrauma or atrophy or fibrosis, and idiopathic causes. Scapulothoracic bursitis and crepitus remain primarily clinical diagnoses. However, imaging studies or local injections may also be helpful. The initial treatment of scapulothoracic bursitis and scapulothoracic crepitus should be conservative. Intevension procedure is best for treating modalitis for scapulothoracic dysfunction, most reports have demonstrated well to excellent outcomes in a significantly high percentage of patients.Conclusions:Clearly, the best initial approach to these conditions is a conservative treatment like nonsteroidal antiinflammatory drugs plan that combines scapular strengthening, postural reeducation, and core strength endurance. If an appropriate trial of nonoperative management proves unsuccessful, local non invesiveintervension can produce good results.

Are craniocervical flexion test and the pectoralis minor index useful tests for patients with subacromial pain syndrome? / Are craniocervical flexion test and the pectoralis minor index useful tests for patients with subacromial pain syndrome?

Cervical disorders and the shortening of the pectoralis minor are advocated to play an important role in patients with subacromial pain syndrome, despite the absence of evidence. This study aimed to compare the deep cervical flexor muscle function and the shortening of the pectoralis minor between patients with subacromial pain syndrome and controls. Secondarily, this study aimed to analyze the relationship of clinical tests with pain and disability among patients. This is a case-control study with 32 patients with subacromial pain syndrome [mean age: 33 ± 6.9 years; sex: 22 (65.6%) men; right dominance: 31 (96.9%)] and 32 controls matched for age, sex, handedness, and affected side. Participants filled the Numerical Pain Rating Scale, the Shoulder Pain and Disability Index; and performed the clinical tests which were compared between patients and controls. Pectoralis minor length of the patient's group (median = 9.0) was similar to the controls (median = 9.7) (U = 421.5; p = 0.22). The deep neck muscle function presented no statistical difference between patients and controls (χ2 = 4.319; p = 0.504). There was no statistically significant correlation between clinical tests and patient self-reported measures. Therefore, deep cervical flexor muscle and the pectoralis minor muscle were not impaired in patients with subacromial pain syndrome and did not show a relationship with self-reported measures.

Distúrbios cervicais e o encurtamento do músculo peitoral menor são apontados como tendo um papel importante em pacientes com síndrome da dor subacromial, apesar da ausência de evidências. Este estudo teve como objetivo comparar a função dos músculos flexores cervicais profundos e o encurtamento do músculo peitoral menor entre pacientes com síndrome da dor subacromial e controles. Secundariamente, este estudo objetivou analisar a relação dos testes clínicos com a dor e incapacidade entre os pacientes com síndrome da dor subacromial. Trata-se de um estudo caso-controle com 32 pacientes com síndrome da dor subacromial [idade: 33 ± 6,9 anos; sexo: 22 (65,6%) homens; dominância direita: 31 (96,9%)] e 32 controles pareados por idade, sexo, lateralidade e lado afetado. Os participantes preencheram a Numerical Pain Rating Scale, o Shoulder Pain and Disability Index, realizaram os testes clínicos e os resultados dos pacientes e controles foram comparados. O comprimento do músculo peitoral menor no grupo de pacientes (mediana = 9,0) foi semelhante ao grupo controle (mediana = 9,7) (U = 421,5; p = 0,22). A função do músculo flexor cervical profundo não apresentou diferença estatística entre pacientes e controles (χ2 = 4,319; p = 0,504). Não houve correlação estatisticamente significativa entre os testes clínicos e as medidas relatadas pelos pacientes. Portanto, o músculo flexor cervical profundo e o músculo peitoral menor não foram prejudicados em pacientes com síndrome da dor subacromial e não mostraram relação com medidas autorreferidas.

Acupuncture therapy reduces cervical and shoulder pain in patients with stroke / 中国基层医药

Objective:To investigate the clinical effects of acupuncture therapy on post-hemiplegia neck and shoulder pain.Methods:Eighty patients with post-stroke hemiplegia with neck and shoulder pain who received treatment in Department of Acupuncture, Massage and Physiotherapy, Zhejiang Provincial Armed Police Corps Hospital between December 2020 and June 2021 were included in this study. They were randomly assigned to undergo either conventional rehabilitation treatment and analgesic tablets (control group, n = 40) or conventional rehabilitation treatment, analgesic tablets and acupuncture therapy in combination (observation group, n = 40). Traditional Chinese medicine efficacy, western medicine efficacy, degree of neurological deficits, ability of daily living, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, traditional Chinese medicine efficacy and western Chinese medicine efficacy in the observation group were significantly higher than those in the control group (87.50% vs. 52.50%, 82.50% vs. 55.00%), and the incidence of adverse reactions in the observation group was significantly lower than that in the control group (17.50% vs. 42.50%, χ2 = 21.48, 16.33, 9.12, all P < 0.05). In the control group, National Institutes of Health Stroke Scale (NIHSS) score measured after treatment was significantly lower than that measured before treatment [(7.58 ± 1.87) points vs. (14.87 ± 1.36) points, t = -9.58, P < 0.001], and Barthel Index (BI) measured after treatment was significantly higher than that measured before treatment [(53.78 ± 1.34) points vs. (37.92 ± 1.74) points, t = 6.35, P < 0.001]. In the observation group, NIHSS score measured after treatment was significantly lower than that measured before treatment [(5.44 ± 2.11) points vs. (14.51 ± 0.34) points, t = -12.69, P < 0.001], and BI measured after treatment was significantly higher than that measured before treatment [(62.02 ± 0.68) points vs. (37.73 ± 1.58) points, t = 7.45, P < 0.05]. BI post-measurement in the observation group was significantly higher than that in the control group [(62.02 ± 0.68) points vs. (53.78 ± 1.34) points, t = 4.35, P < 0.05]; NIHSS score post-measurement in the observation group was significantly lower than that in the control group [(5.44 ± 2.11) points vs. (7.58 ± 1.87) points, t = -8.48, P < 0.05]. Conclusion:Acupuncture treatment for post-hemiplegia neck and shoulder pain can markedly reduce pain in patients, improve prognosis and increase clinical efficacy.

Prevalence and workload-related risk factors of neck-shoulder pain among nurses in Hunan tertiary general hospitals / 环境与职业医学

Background Neck-shoulder pain is one of the most common discomfort symptoms among nursing staff, mostly caused by a heavy workload, restricted workstation, and prolonged poor posture. Objective To investigate the prevalence of neck-shoulder pain among nursing staff in tertiary general hospitals in Hunan Province, and to analyze workload-related risk factors. Methods From October to December 2018, a multi-stage stratified randomized cluster sampling method was adopted to select a total of 1 200 nursing staff who met the inclusion andexclusion criteria in six tertiary general hospitals from five geographic subdivisions of Hunan Province were selected. A self-designed questionnaire was used to collect demographic characteristics, and past 1-month prevalence of neck-shoulder pain, a neck disability index (NDI) was used to assess the impact of neck pain on daily life, and functional disability was graded by the index of impaired neck function; a self-designed questionnaire was adopted to evaluate potential workload-related risk factors (working time, postural load, and force load) of neck-shoulder pain after a Delphi expert consultation. A total of 1 161 valid questionnaires were returned, and χ２test and logistic regression model were used to screen the potential risk factors for neck-shoulder pain. Results The prevalence rate of neck-shoulder pain in the past 1 month was 87.5% (1 016/1 161) and varied by different characteristics of the nursing staff, ranging from 76.9% to 91.2%. The scores of the 10 items of the NDI ranged from 0 to 5, but most of them were 0, 1, and 2; of the 10 items, neck pain had the greatest impact on sleep (1.30±1.21) and the least impact on self-care behaviors (0.35±0.65). The index of impaired neck function showed that the majority (65.4%) of nurses had mild cervical spine dysfunction and 30.1% had moderate cervical spine dysfunction. The univariate analysis results revealed that 24 out of the 31 workload-related risk factors had significant differences, and further multiple analysis results showed that three variables entered the logistic regression model. Under the same conditions, nurses with ≥5 h of cumulative head-down tasks per shift had 3.03 times higher neck-shoulder pain risks compared with those with ＜1 h. Compared with “occasionally or never”, nurses who “sometimes” and “often” tilted their necks back and maintained this posture for a long time showed 2.36 and 2.94 times higher risks for neck-shoulder pain respectively. The nurses who reported “sometimes” and “often” having difficulty using their force at work due to unnatural posture had 2.78 times and 7.08 times higher neck-shoulder pain risks than those who “occasionally or never” respectively. Conclusion The reported rate of neck-shoulder pain among nurses in tertiary general hospitals in Hunan Province is high, but most of them are mild dysfunction. Working hours and posture load may affect the risk of neck-shoulder pain.

Application of ultrasound-guided adhesiolysis combined with platelet-rich plasma in the treatment of rotator cuff injuries / 中国基层医药

Objective:To investigate the efficacy of ultrasound-guided adhesiolysis combined with platelet-rich plasma in the treatment of rotator cuff injuries.Methods:The clinical data of 103 patients with rotator cuff injuries treated in The 72 nd Military Hospital of PLA from December 2017 to December 2019 were retrospectively analyzed. The patients were divided into two groups according to the treatment methods. The control group ( n = 48) was treated with ultrasound-guided adhesiolysis. The study group ( n = 55) was treated with ultrasound-guided adhesiolysis and intra-articular injection of platelet rich plasma. Therapeutic effects, pain score, shoulder function score, shoulder range of motion, healing rate, and re-tear rate were compared between the control and study groups. Results:Total effective rate was significantly higher in the study group than in the control group (96.36% vs. 81.25%, χ2 = 6.14, P < 0.05). Pain score in each group was significantly decreased after treatment compared with before treatment [study group: (1.69 ± 0.81) points vs. (6.13 ± 1.28) points; control group: (3.22 ± 1.05) points vs. (6.13 ± 1.28) points, t = 31.510, 8.33, both P < 0.001]. The University of California at Los Angeles (UCLA) shoulder score in each group was significantly increased after treatment compared with before treatment [study group: (33.26 ± 3.81) points vs. (14.03 ± 2.96) points; control group: (28.81 ± 3.20) points vs. (13.92 ± 3.03) points, t = 42.13, 33.12, both P < 0.001]. Constant-Murley Score in each group was significantly increased after treatment compared with before treatment [study group: (94.22 ± 4.15) points vs. (55.29 ± 8.18) points; control group: (82.11 ± 8.13) points vs. (56.33 ± 7.83) points; t = 46.83, 22.38, both P < 0.001]. After treatment, pain score was significantly lower in the study group than in the control group [(1.69 ± 0.81) points vs. (3.22 ± 1.05) points, t = 8.33, P < 0.001]. UCLA score and CMS were significantly higher in the study group than in the control group [(33.26 ± 3.81) points vs. (28.81 ± 3.20) points, (94.22 ± 4.15) points vs. (82.11 ± 8.13) points, t = 6.37, 9.70, both P < 0.001]. After treatment, there were improvements in flexion [study group: (159.26 ± 13.51)° vs. (85.26 ± 11.35)°; control group: (150.22 ± 14.35)° vs. (86.33 ± 11.51)°; t = 45.15, 34.23, both P < 0.001], internal rotation at 90° abduction [study group: (83.64 ± 5.29)° vs. (60.33 ± 4.12)°; control group: (76.81 ± 4.82)° vs. (60.61 ± 4.51)°; t = 36.74, 24.06, both P < 0.001], abduction [study group: (161.29 ± 10.76)° vs. (72.91 ± 5.16)°; control group: (152.81 ± 11.84) ° vs. (73.26 ± 5.22)°; t = 82.34, 64.61, both P < 0.001], external rotation at 90° abduction [study group: (87.82 ± 3.04)° vs. (4.29 ± 5.18)°; control group: (80.22 ± 4.13)° vs. (80.22 ± 4.13)°; t = 42.46, 21.55, both P < 0.001] , and external rotation in neutral position [study group: (43.18 ± 3.20)° vs. (22.85 ± 4.12)°; control group: (37.26 ± 4.12)° vs. (22.64 ± 3.95)°; t = 41.19, 25.10, both P < 0.001] in each group compared with before treatment. After treatment, range of motion of the shoulder in the above positions was significantly higher in the study group than in the control group [flexion: (159.26 ± 13.51)° vs. (150.22 ± 14.35)°; internal rotation at 90° abduction: (83.64 ± 5.29)° vs. (76.81 ± 4.82)°; abduction: (161.29 ± 10.76)° vs. (152.81 ± 11.84)°; external rotation at 90° abduction: (87.82 ± 3.04)° vs. (80.22 ± 4.13)°; external rotation in neutral position: (43.18 ± 3.20)° vs. (37.26 ± 4.12)°, t = 3.29, 6.81, 3.81, 10.72, 8.20, all P < 0.001]. There was no significant difference in healing rate between the study and control groups (1.82% vs. 16.67%, χ2 = 5.35, P < 0.05). Conclusion:Ultrasound-guided adhesiolysis combined with platelet-rich plasma is highly effective in the treatment of rotator cuff injuries because it can greatly improve shoulder function, reduce pain degree, and increase the range of motion of the shoulder.

Acromial type in Brazilian young adults: a radiological study / Tipo acromial em adultos jovens brasileiros: um estudo radiológico

Introduction: curved and hooked acromia play a key role in shoulder impingement syndrome. Little is known about acromial type in the Brazilian population. Aim: To describe the acromial profile of Brazilian young adults; to evaluate its correlation with gender and handedness and the occurrence of symmetry between the genders. Methodology: forty acromia in 20 Brazilian adults of both genders, aged 21-25 years, were studied. The acromial type was classified through the Bigliani/Epstein method using radiographs in supraspinatus outlet view. Results: as there was no gender difference in occurrences of acromial type, we considered the male and female groups together. Thus, among the 20 right acromia, we found 5 type I (25%), 8 type II (40%) and 7 type III (35%). Among the 20 left acromia, we found 4 type I (20%), 11 type II (55%) and 5 type III (25%). The only left-handed volunteer (100%) presented acromial type III in both the right and the left shoulder. Among the 19 right-handed volunteers, 5 (26.3%) presented right acromion type I, 8 (42.1%) had type II and 6 (31.6%) had type III; for the left acromion, 4 (21.1%) presented type I, 11 (57.9%) had type II and 4 (21.1%) had type III. Acromial symmetry occurred in 60% of females and 70% of males. Conclusion: type II acromion was predominant, in both the right and the left shoulder in Brazilian young adults. There was no correlation between acromial type and gender. It was not possible to analyze the correlation between acromial type and handedness. Acromial type tended to be symmetrical in our sample.

Introdução: o acrômio curvo e gancho desempenham um papel fundamental na Síndrome do impacto do ombro. Pouco se sabe sobre o tipo acromial na população brasileira. Objetivo: descrever o perfil do tipo acromial em adultos jovens brasileiros e avaliar sua correlação com o gênero e a lateralidade e a ocorrência de simetria entre os sexos. Metodologia: foram estudados 40 acrômios de 20 adultos brasileiros, de ambos os sexos, com idade entre 21 e 25 anos. O tipo acromial foi classificado pelo método de Bigliani/ Epstein nas radiografias de perfil de escápula. Resultados: como não houve diferença na ocorrência do tipo acromial quanto ao gênero, consideramos os grupos masculino e feminino juntos. Assim, dos 20 acrômios direitos, foram encontrados 5 (25%) do tipo I, 8 (40%) do tipo II e 7 (35%) do tipo III, enquanto que dos 20 acrômios esquerdos, foram encontrados 4 (20%) tipo I, 11 (55%) tipo II e 5 (25%) tipo III. O único voluntário canhoto (100%) apresentou para o ombro direito e esquerdo o tipo acromial III. Dos 19 voluntários destros, 5 (26,3%) apresentavam acrômio direito tipo I, 8 (42,1%) tipo II e 6 (31,6%) tipo III; para o acrômio esquerdo, 4 (21,1%) apresentavam tipo I, 11 (57,9%) tipo II e 4 (21,1%) tipo III. A simetria acromial ocorreu nos grupos feminino (60%) e masculino (70%). Conclusão: o acrômio tipo II foi o mais predominante para os ombros direito e esquerdo em adultos jovens brasileiros. Não houve correlação entre o tipo de acromial e o gênero. Não foi possível analisar a correlação entre o tipo acromial e a lateralidade. O tipo acromial tende a ser simétrico em na amostra estudada.

Shoulder Injury after Vaccination: A Systematic Review / Lesão de ombro após a vacinação: Uma revisão sistemática

Abstract Adverse reactions to vaccine injections are usually mild and incredibly rare in nature, but multiple cases of shoulder events including bursitis, generalized pain or decreased range of motion have been reported following routine vaccine administrations. These events are known as Shoulder Injury Related to Vaccine Administration or SIRVA. A systematic review of literature was performed to identify all published accounts of SIRVA. Twenty-seven papers reporting one or more accounts of SIRVA were identified. The most common vaccination involved was the Influenza vaccine. The most common symptoms were pain that began in 48 hours or less and loss of shoulder range of motion. The most common treatment modalities were physical therapy, corticosteroid injections and anti-inflammatory medication; but in some patients, surgery was required. Regardless of intervention, the vast majority of outcomes demonstrated improved pain and functional except in the occasions of nerve injury. The etiology of SIRVA injuries has multiple possibilities including needle length, mechanical injury from needle overpenetration and the possibility of an immune inflammatory response from the vaccine components, but a unique definitive test or quantifiably result does not yet exist.

Resumo As reações adversas às injeções de vacina tendem a ser brandas e são incrivelmente raras. No entanto, vários casos de eventos em ombros, como bursite, dor generalizada ou diminuição da amplitude de movimento, foram relatados após vacinações de rotina. Esses eventos são conhecidos como lesões em ombro relacionadas à administração de vacina (SIRVA, do inglês shoulder injury related to vaccine administration). Uma revisão sistemática da literatura foi realizada para identificar todos os relatos publicados de SIRVA. Vinte e sete artigos que relataram um ou mais casos de SIRVA foram encontrados. A vacina mais comumente citada foi a vacina contra influenza. Os sintomas mais comuns foram dor com início em até 48 horas e perda da amplitude de movimento do ombro. As modalidades de tratamento mais comuns foram fisioterapia, injeções de corticosteroides e administração de medicamentos anti-inflamatórios; alguns pacientes, porém, precisaram de cirurgia. Independentemente da intervenção, a grande maioria dos casos apresentou melhora da dor e da função, à exceção dos pacientes com lesão nervosa. A SIRVA tem múltiplas possíveis etiologias, inclusive comprimento da agulha, lesão mecânica por penetração excessiva da agulha e resposta inflamatória aos componentes da vacina; no entanto, ainda não há um exame definitivo ou resultado quantificável.

Tuberculosis en húmero proximal. Un diagnóstico infrecuente en infecciones articulares / Tuberculosis in the proximal humerus. A rare diagnosis in joint infections

Resumen La incidencia de Tb osteoarticular es mucho menor que la pulmonar, representando 1-2% de los casos de Tuberculosis (Tb) y el 10% de los casos de Tb extrapulmonar, por lo que usualmente no es considerada para el diagnóstico diferencial de pacientes con enfermedad articular. Su diagnóstico es difícil y se basa en hallazgos clínicos, radiológicos, bacteriológicos e histológicos. Las lesiones extrapulmonares son paucibacilares y las muestras, en la mayoría de los casos, difíciles de obtener, por lo que el diagnóstico a menudo es simplemente presuntivo. La tuberculosis articular en etapas tempranas, presenta manifestaciones clínicas e imagenológicas inespecíficas. Esto puede facilitar la progresión de la enfermedad local, generando lesiones osteoarticulares graves y, finalmente, la destrucción articular. Se presenta el caso de una paciente de 60 años, intervenida quirúrgicamente por presentar manifestaciones clínicas e imagenológicas compatibles con una ruptura del manguito rotador, y cuya evolución tórpida posoperatoria, llevó al diagnóstico bacteriológico de tuberculosis de húmero proximal.

Abstract The incidence of osteoarticular TB is much lower than that of the lung, representing 1-2% of TB cases and 10% of extrapulmonary TB cases, so it is often not considered for the differential diagnosis of patients with joint disease. Its diagnosis is difficult and is based on clinical, radiological, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and specimens, in most cases, difficult to obtain, so the diagnosis is often simply presumptive. Joint tuberculosis in early stages presents nonspecific clinical and imaging manifestations. This can lead to the progression of the local disease, generating severe osteoarticular lesions and, finally, joint destruction. We present the case of a 60-year-old patient who underwent surgery due to clinical and imaging manifestations compatible with a rotator cuff tear, and whose torpid postoperative evolution led to the bacteriological diagnosis of proximal humerus tuberculosis.

Analysis of the spine posture, mobility and strength in healthy individuals with and without scapular dyskinesis / Análise da postura, mobilidade e força da coluna vertebral em indivíduos saudáveis com e sem discinese escapular

Spine posture, mobility and strength can be associated with changes in scapular movement and shoulder pain. However, these aspects have not been assessed in healthy individuals with scapular dyskinesis without shoulder and/or back pain. Objective: To analyze spine posture, mobility and strength in healthy individuals with and without scapular dyskinesis. Method: Cross-sectional study, fifty-two college-aged individuals were divided into two groups, according to scapular dyskinesis testing: a group without scapular dyskinesis (n= 19; age= 22.95±2.86 years; BMI= 22.97±3.12 kg/m²; 10 males) and another with scapular dyskinesis (n= 33; age= 22.06±2.73 years; BMI= 22.14±3.22 kg/m²; 10 males). Posture of the head and shoulders was analyzed from photographs by a postural assessment software (PAS/SAPO). Thoracic kyphosis and range of motion of the cervical and thoracolumbar spine were measured by a digital inclinometer, and the strength of the cervical and thoracolumbar spine muscles by a hand-held dynamometer. Intergroup comparison for all the variables was conducted using analysis of variance (one-way ANOVA), considering p≤0.05 as significant. Results: No intergroup difference was found for spine posture (p= 0.18-0.99), mobility (p= 0.23-0.96) and strength (p= 0.42-0.99). Conclusion: Spine posture, mobility and strength do not differ between healthy individuals with and without scapular dyskinesis. The outcomes suggest that scapular dyskinesis may be related to interpersonal variations. Future prospective studies be conducted in order to verify if these variables can change and influence the development of shoulder pain.

A postura, mobilidade e força da coluna podem estar associadas com mudanças no movimento da escápula e dor no ombro. Objetivo: Analisar a postura da coluna vertebral, mobilidade e força em indivíduos saudáveis com e sem discinese escapular. Método: Estudo transversal com cinquenta e dois indivíduos em idade universitária foram divididos em dois grupos, de acordo com o teste de discinese escapular: um grupo sem discinese escapular (n= 19; idade= 22,95±2,86 anos; IMC= 22,97±3,12 kg/m²; 10 masculino) e outro com discinese escapular (n= 33; idade= 22,06±2,73 anos; IMC= 22,14±3,22 kg/m²; 10 masculino). A postura da cabeça e dos ombros foi analisada a partir de fotografias por um software de avaliação postural (PAS/SAPO). A cifose torácica e a amplitude de movimento da coluna cervical e torácica foram medidas por um inclinômetro digital, e a força dos músculos cervical e torác lombar por um dinamômetro portátil. A comparação intergrupo para todas as variáveis foi realizada utilizando-se a análise de variância (ANOVA unidirecional), considerando p≤0,05 como significativa. Resultados: Não foi encontrada diferença entre grupos postura (p= 0,18-0,99), mobilidade (p= 0,23-0,96) e força da coluna (p= 0,42-0,99). Conclusão: Postura, mobilidade e força da coluna vertebral não diferem entre indivíduos saudáveis com e sem discinese escapular. Os resultados sugerem que a discinese escapular pode estar relacionada a variações interpessoais. Estudos prospectivos futuros devem ser conduzidos afim de verificar se essas variáveis podem modificar e influenciar o desenvolvimento da dor no ombro.

Contralateral Humerus Avascular Necrosis Diagnosed Immediately after Radiotherapy in a Patient with Breast Cancer

ABSTRACT Radiotherapy (RT) is an important component of treatment for malignant tumours, and avascular necrosis (AVN), which is often associated with high morbidity and disability, frequently accompanies this type of therapy. It generally develops in the same extremity with the treated region and may continue long after the treatment is completed. Early identification of AVN has the potential to reduce morbidity and improve the patient's quality of life. Herein, we present a case of contralateral humerus avascular necrosis diagnosed immediately after the first round of RT in a patient with breast cancer.

Observation on Tuina plus needling the distal acupoints along the pathway of meridians for shoulder periarthritis / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) plus needling the distal acupoints along the pathway of meridians for shoulder periarthritis (SP). Methods: A total of 70 patients with SP were divided into an observation group and a control group using the random number table method, with 35 cases in each group. The patients in the observation group were treated by Tuina combined with needling distal acupoints along the pathway of meridians, while those in the control group only received the same Tuina treatment as in the observation group. The visual analog scale (VAS) and shoulder joint function were scored before and after treatment, and the efficacy after treatment was evaluated. Results: After three courses of treatment, the total effective rate of the observation group was 94.3％, while the total effective rate of the control group was 80.0％, showing a statistical difference (P<0.05). After treatment, the VAS scores of the two groups were significantly lower than the baseline scores (P<0.01), and the VAS score of the observation group was lower than that of the control group (P<0.01). After treatment, the total scores of internal rotation, external rotation, back touching, ear touching and motion function in the two groups were significantly higher than those before treatment (P<0.01), and the above five scores in the observation group were significantly higher than those in the control group (P<0.01). Conclusion: Tuina combined with needling the distal acupoints along the pathway of meridians is more effective than Tuina alone in treating SP. The combined therapy can relieve the pain and improve joint function more effectively.
