Association between sleep quality and pain in young amateur athletes / Asociación entre calidad del sueño y dolor en jóvenes atletas amateurs / Associação entre qualidade do sono e dor em jovens atletas amadores

ABSTRACT Introduction: It has been shown that there is a close association between sleep quality and pain. In young athletes, sleep disorders and pain have a particularly high prevalence; however, the relationship between them has not been widely studied. Objective: To study the association between sleep quality and pain in young athletes. Methods: A cross-sectional study was conducted in which 71 young amateur athletes (39 males) were included. The mean age was 16.9 ± 1.2 years, with 6.5 ± 3.2 years of sports practice and 5.2 ± 1.2 hours of training per week. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The participants were classified according to sleep quality, as PSQI-I = without sleep disorders, PSQI-II = requiring medical assistance and PSQI-III = requiring medical assistance and treatment. Also, pain intensity was assessed on the Numerical Rating Scale, both at rest (NRSr) and during sports activity (NRSs), along with pain duration. Results: The individuals classified as PSQI-III presented higher NRSr (Mdn = 2.0; IQR = 4.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.04) and higher NRSs (Mdn = 4.0; IQR = 5.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.03) than the individuals classified as PSQI-I. No differences were observed in relation to pain duration. The PSQI score was positively but weakly associated with NRSr (rs = 0.24, p=0.046) and NRSs (rs = 0.27, p = 0.03) but not with pain duration. Conclusion: Young athletes with lower levels of sleep quality show higher levels of pain at rest and during sports practice. Therefore, sleep quality and pain should be considered in the routine assessment of young athletes, by technical and health teams. Level of evidence III; type of study: Cross-sectional .

RESUMEN Introducción: Se demostró que existe estrecha relación entre calidad del sueño y dolor. En atletas jóvenes, los disturbios del sueño y dolor tienen prevalencia bastante alta, sin embargo, la relación entre ellos no fue ampliamente estudiada. Objetivo: Estudiar la asociación entre calidad del sueño y dolor en atletas jóvenes. Métodos: Fue realizado un estudio transversal, en el cual fueron incluidos 71 atletas jóvenes amateurs (39 hombres). El promedio de edad fue de 16,9 ± 1,2 años, con 6,5 ± 3,2 años de práctica deportiva y 5,2 ± 1,2 horas de entrenamiento por semana. La calidad del sueño fue evaluada por medio del Índice de Calidad del Sueño de Pittsburgh (PSQI). Los participantes fueron clasificados de acuerdo con la calidad del sueño, PSQI-I= sin disturbios del sueño, PSQI-II= requiere atención médica y PSQI-III= requiere atención médica y tratamiento. Además, la intensidad del dolor fue evaluada en la Escala de Evaluación Numérica en reposo (EANr) y durante la actividad deportiva (EANe), juntamente con la duración del dolor. Resultados: Los individuos clasificados como PSQI-III presentaron mayor valor en el EANr (Mdn = 2,0; IQR = 4,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,04) y EANe mayores (Mdn = 4,0; IQR = 5,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,03) que los individuos clasificados con PSQI-I. No fue observada ninguna diferencia con relación a la duración del dolor. El puntaje del PSQI fue positivo y con débil asociación a EANr (rs = 0,24, p=0.046) y EANe (rs = 0,27, p = 0,03), pero no con la duración del dolor. Conclusión: Los atletas jóvenes con niveles más bajos de calidad del sueño tienen niveles más elevados de dolor en reposo y durante la práctica deportiva. Por lo tanto, la calidad del sueño y el dolor deben ser considerados por los equipos técnicos y de salud en la evaluación rutinaria de atletas jóvenes. Nivel de evidencia III;Tipo de estudio: Transversal.

RESUMO Introdução: Demonstrou-se que existe estreita associação entre qualidade do sono e dor. Em atletas jovens, distúrbios do sono e dor têm prevalência bastante alta, no entanto, a relação entre eles não foi amplamente estudada. Objetivo: Estudar a associação entre qualidade do sono e dor em atletas jovens. Métodos: Foi realizado um estudo transversal, no qual foram incluídos 71 atletas jovens amadores (39 homens). A média de idade foi de 16,9 ± 1,2 anos, com 6,5 ± 3,2 anos de prática esportiva e 5,2 ± 1,2 horas de treinamento por semana. A qualidade do sono foi avaliada por meio do Índice de Qualidade do Sono de Pittsburgh (PSQI). Os participantes foram classificados de acordo com a qualidade do sono, PSQI-I = sem distúrbios do sono, PSQI-II = requer atendimento médico e PSQI-III = requer atendimento médico e tratamento. Além disso, intensidade da dor foi avaliada na Escala de Avaliação Numérica em repouso (EANr) e durante a atividade esportiva (EANe), juntamente com a duração da dor. Resultados: Os indivíduos classificados como PSQI-III apresentaram maior valor no EANr (Mdn = 2,0; IQR = 4,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,04) e EANe maiores (Mdn = 4,0; IQR = 5,0 vs. Mdn = 0,0; IQR = 2,0; p = 0,03) do que os indivíduos classificados com PSQI-I. Nenhuma diferença foi observada com relação à duração da dor. O escore do PSQI foi positivo e com fraca associação a EANr (rs= 0,24, p=0.046) e EANe (rs= 0,27, p = 0,03), mas não com a duração da dor. Conclusão: Atletas jovens com níveis mais baixos de qualidade do sono têm níveis mais elevados de dor em repouso e durante a prática esportiva. Portanto, a qualidade do sono e a dor devem ser consideradas pelas equipes técnicas e de saúde na avaliação rotineira de atletas jovens. Nível de evidência III; Tipo de estudo: Transversal.

Nuevos avances en el conocimiento de la historia natural de la displasia fibrosa / News advances in the knowledge of natural history of the fibrous dysplasia

La displasia fibrosa (DF) es una enfermedad infrecuente del hueso, no hereditaria, producida por una mutación activadora del gen GNAS, responsable de codificar la unidad a-estimuladora de la proteína G (Gsa). La presentación clínica de la enfermedad es muy variada, pues adopta desde formas asintomáticas hasta otras marcadamente sintomáticas. En los últimos años, el análisis exhaustivo de bases de datos de pacientes con DF ha permitido conocer más sobre su historia natural. En este artículo se revisa la información actualmente disponible sobre algunos aspectos que ayudarán al mejor enfoque clínico del paciente, como son: la utilidad clínica de los marcadores óseos, los factores pronósticos para el desarrollo de fracturas, la DF como condición predisponente para el desarrollo de tumores específicos, nuevas perspectivas sobre la fisiopatología del dolor óseo y nuevas estrategias terapéuticas. Un mayor conocimiento sobre la historia natural de esta enfermedad finalmente redundará en la mejor calidad de vida de los pacientes con DF. (AU)

Fibrous dysplasia (FD) is an infrequent, non-hereditary bone disease caused by a somatic mutation of the GNAS gene, responsible for encoding the a-subunit of the G-protein (Gsa). The clinical presentation of the disease varies greatly, with some patients being asymptomatic and others markedly symptomatic. The exhaustive analysis of the database from patients with FD has allowed to learn more about the natural history of this disease. This article reviews the current information available on the clinical utility of bone markers, the prognostic factors for the occurrence of fractures, the evidence supporting as a predisposing condition for the development of specific tumors, new perspectives on the pathophysiology of bone pain, and emerging therapeutic strategies. A greater understanding of the natural history of this disease will allow to make better medical decisions, which will ultimately contribute to improve FD patients' quality of life. (AU)

Impacto da dor musculoesquelética na incapacidade funcional / Impacto del dolor musculoesquelético en la incapacidad funcional / Impact of musculoskeletal pain in functional disability

RESUMO O objetivo foi estimar a prevalência de incapacidade para realizar tarefas de vida diária e identificar associação com dor e fatores sociodemográficos. Trata-se de um estudo transversal, com amostra de conveniência, composta por indivíduos que buscaram ativamente assistência à saúde em um município de pequeno porte com queixas de dor musculoesquelética e dificuldades na realização de atividades de vida diária. Compuseram a amostra 766 indivíduos. Foram aplicados questionários para avaliar o grau de dificuldade de realização de atividades de vida diária e dor (Questionário Nórdico de Queixas Musculoesqueléticas e Escala Numérica de Dor). Foram estimadas as prevalências de incapacidade e dor, bem como foram construídos cinco modelos de regressão logística para incapacidade considerando sexo, idade, ocupação e presença e características da dor. Os dados encontrados mostraram que a prevalência de alguma dificuldade para realizar atividades de vida diária foi de 87,6%, de muita dificuldade 66,1%; a de dor musculoesquelética foi de 67,5%. Os indivíduos apresentaram incapacidade para realização de 3,6 atividades de vida diária em média. A dor foi o principal fator de associação para explicá-la (OR 9,9; IC95% 5,9-16,5), seguida da idade. A dificuldade na execução de atividades de vida diária foi associada à dor em membros inferiores, com frequência maior que quatro dias na semana, início há mais de cinco anos e intensidade forte ou insuportável nos episódios de crise. As prevalências de incapacidade e dores foram altas. A dor musculoesquelética e a idade impactaram na incapacidade funcional. Este estudo contribui para direcionar a construção de ações de cuidado que visem minimizar e prevenir dificuldades para realizar tarefas do dia a dia.

RESUMEN El objetivo fue estimar la prevalencia de incapacidad para realizar tareas de la vida diaria e identificar una asociación con el dolor y los factores sociodemográficos. Este es un estudio transversal, con una muestra de conveniencia compuesta de individuos que buscaron activamente asistencia médica en un municipio de pequeño porte, quejándose de dolor musculoesquelético y dificultades para llevar a cabo actividades de la vida diaria. La muestra comprendió 766 individuos. Se aplicaron cuestionarios para evaluar el grado de dificultad en la realización de actividades de la vida diaria y el dolor (Cuestionario nórdico musculoesquelético y Escala numérica del dolor). Se estimaron las prevalencias de incapacidad y dolor, así como se construyeron cinco modelos de regresión logística para la incapacidad considerando el sexo, la edad, la ocupación y la presencia y características del dolor.

ABSTRACT The objective is to estimate the prevalence of incapacity to perform tasks of daily living and to identify its association with pain and sociodemographic factors. This is a cross-sectional study, with a convenience sample, composed of individuals who actively sought healthcare in a small city with complaints of musculoskeletal pain and difficulties in carrying out activities of daily living. The sample comprised 766 individuals. Questionnaires were applied to assess the degree of difficulty in performing activities of daily living and pain (Nordic Musculoskeletal Complaints Questionnaire and Numerical Pain Scale). The prevalence of disability and pain was estimated, as well as five logistic regression models for disability were constructed considering sex, age, occupation and presence and characteristics of pain. The data found showed that the prevalence of some difficulty in performing activities of daily living was 87.6%, with a lot of difficulty 66.1%; musculoskeletal pain was 67.5%. The individuals were unable to perform 3.6 activities of daily living on average. Pain was the main association factor to explain it (OR 9.9; 95%CI 5.9-16.5), followed by age. Difficulty in performing activities of daily living was associated with pain in the lower limbs, with a frequency greater than four days a week, beginning more than five years ago and severe or unbearable intensity in crisis episodes. The prevalence of disability and pain was high. Musculoskeletal pain and age impacted functional disability. This study contributes to direct the construction of care actions that aim to minimize and prevent difficulties to perform daily tasks.

The musculoskeletal impairment negatively impacts the quality of life of children and adolescents with psoriasis

Abstract Background The severity of nail disease, the presence of arthralgia and fatigue are predictors of development of psoriatic arthritis (PsA) in patients with psoriasis (Pso). In children, little is known about the musculoskeletal (MSK) impairment in patients with Pso and its effect on health-related quality of life (HRQoL). Objectives To determine the frequencies of pain and MSK inflammation (i.e., arthritis, enthesitis, and sacroiliitis) among children and adolescents with Pso and its relationship to HRQoL and fatigue. Methods Pediatric patients with Pso underwent a rheumatologic physical examination to evaluate synovitis, enthesalgia, sacroiliac joint (SIJ) pain and tender points of fibromyalgia. The core set of domains recommended by the GRAPPA - OMERACT to be measured in PsA studies was assessed. Ultrasound (US) was performed in clinical cases of enthesitis, and magnetic resonance imaging (MRI) was performed in cases of SIJ pain. Results Forty-three participants (10 ± 2.9 years old) were evaluated. Pain on palpation of the entheses was observed in 10 (23.2%) patients and pain on SIJ palpation was observed in 3 (7%). No patient presented with synovitis; one presented with enthesitis on US, but MRI did not confirm sacroiliitis in any case. Patients with MSK pain had greater skin disease severity (PASI 5.4 vs. 2, p < 0.01), worse fatigue, and lower HRQoL scores on all instruments used. The estimated risk of HRQoL impairment was eight times higher in the presence of MSK pain, which was an independent predictive factor. With a NAPSI greater than 30, the probability of pain was greater than 80%. Conclusion MSK pain is frequent among children with Pso, related to the severity of skin and nail disease, and negatively affects HRQoL. The typically used complementary exams might not detect the inflammatory process caused by Pso.(AU)

Gait in children and adolescents with idiopathic musculoskeletal pain

Abstract Introduction: Musculoskeletal pain is a constant complaint in pediatric practice. The pain may be related to a number of organic diseases and / or be part of the amplified musculoskeletal pain syndromes. Idiopathic musculoskeletal pain (IMSP) is defined as the presence of intermittent pain in three or more body regions for at least three months, excluding organic diseases that could explain the symptoms. Objective: To study the gait of children and adolescents with IMSP by dynamic baropodometry. Methodology: Thirty-two patients with IMSP and 32 healthy controls, matched by age, sex, social class, and body mass index (BMI) were enrolled. All were evaluated for pain intensity through the visual analogue scale (VAS) and gait evaluation using dynamic baropodometry. Results: The mean age of the IMSP group was 13.6 years (SD = 2.1, range 9.8-16.9) and of the control group was 13.5 years (SD = 2.0, range 9.6-16.5). The mean pain scale was 5.4 cm in the IMSP group and 0 cm in the control group (p < 0.001). In gait, the mean right foot velocity of the IMSP group was significantly lower (p = 0.034), the time of the step of the IMSP group was significantly higher (p = 0.003) and the pace of the IMSP group was significantly lower (p = 0.001). Conclusion: In our study we observed differences between the gait of children with IMSP and healthy controls according to the dynamic baropodometry. This finding indicates the need for individualized attention to the gait of children with musculoskeletal pain.

Idiopathic Musculoskeletal Pain in Indian children-Prevalence and Impact on Daily Routine / Prevalência e impacto nas atividades diárias da dor musculoesquelética idiopática em crianças da Índia

ABSTRACT Objectives: To study the prevalence of idiopathic musculoskeletal pain (IMSP) in school going children and its impact on daily life. Methods: One thousand eighteen apparently healthy school children aged 5–16 years were assessed and analysed for IMSP and its associated problems. Standard tests for significance were applied. Results: One hundred and sixty-five (16.2%) children mostly males (55.2%) reported IMSP. Lower limbs (52.1%) were the most common location of pain. More than 1 year of pain history was present in 15%. Thirty-seven percent children complained of discomfort during walking, 30.9%, had pain during physical exercise, 29.2% had difficulty attending lessons and 4.2% had interference in pursuing hobbies. The children were also further sub grouped into preadolescents and adolescents. There was significant difference in pain duration and duration of each pain episode in the two groups (p = 0.01). A significant number of children (21.2%) with IMSP reported school absenteeism (p < 0.001). A significant number of adolescents had history positive for contact sports (p = 0.001). Sleep disturbances were also reported to be higher in children with IMSP (29% vs. 5.7%, p = 0.001). Other associated problems in children with IMSP found were day time tiredness (51.1%), headache (47.3%) and abdominal pain (24.8%). Conclusions: Prevalence of IMSP in school children aged 5–16 yrs was found to be 16.2% and a significant percentage of these children experience interference with daily activities including school absenteeism.

RESUMO Objetivos: Estudar a prevalência de dor musculoesquelética idiopática (DMEI) em crianças em idade escolar e seu impacto nas atividades diárias. Métodos: Foram avaliadas e analisadas 1.018 crianças em idade escolar aparentemente saudáveis entre cinco e 16 anos quanto à presença de DMEI e seus problemas associados. Foram aplicados os testes de significância padrão. Resultados: Relataram DMEI 165 (16,2%) crianças, em sua maior parte do sexo masculino (55,2%). Os membros inferiores (52,1%) foram a localização mais comum da dor. A história de dor presente havia mais de um ano foi encontrada em 15% das crianças; 37% delas queixaram-se de desconforto durante a caminhada, 30,9%, tinham dor durante o exercício físico, 29,2% tinham dificuldade de frequentar as aulas e 4,2% sofriam interferência na participação em passatempos. As crianças foram ainda subagrupadas em pré-adolescentes e adolescentes. Houve diferença estatisticamente significativa na duração da dor e na duração de cada episódio de dor nos dois grupos (p = 0,01). Uma quantidade significativa de crianças com DMEI (21,2%) relatou absentismo escolar (p < 0,001). Uma quantidade significativa de adolescentes tinha história positiva de prática de esportes de contato (p = 0,001). Os distúrbios do sono também foram relatados como maiores em crianças com DMEI (29% vs. 5,7%, p = 0,001). Outros problemas associados encontrados em crianças com DMEI foram o cansaço durante o dia (51,1%), a cefaleia (47,3%) e a dor abdominal (24,8%). Conclusões: A prevalência de DMEI encontrada em crianças entre cinco e 16 anos foi de 16,2%. Uma percentagem significativa dessas crianças relata interferência nas atividades diárias, incluindo absentismo escolar.

Efeito da terapia vocal associada ao biofeedback eletromiográfico em mulheres com disfonia comportamental: ensaio clínico randomizado, controlado e cego / Effect of vocal therapy associated with electromyographic biofeedback in women with behavioral dysphonia: randomized controlled blinded clinical trial

Introdução: as disfonias podem acometer o nível respiratório, glótico e ressonantal/articulatório, limitar a eficiência da comunicação e gerar prejuízos na qualidade de vida. Quando a etiologia da disfonia está relacionada ao uso vocal incorreto, elas são classificadas como comportamentais. Apesar da literatura mostrar a efetividade de alguns métodos e programas de reabilitação vocal, poucos exploram a autopercepção corporal e a participação da musculatura corporal no quadro da disfonia. A fim de melhorar essas questões, a literatura propôs o biofeedback eletromiográfico. Estudos que analisaram esse método são antigos e apresentam heterogeneidade metodológica, o que dificulta sua reprodução. Dessa forma, é necessário analisar o efeito do método por meio de um ensaio clínico para se obter evidências científicas sobre a intervenção para respaldar a prática clínica baseada em evidências. Objetivo: analisar a efetividade e a duração dos efeitos da terapia vocal associada ao biofeedback eletromiográfico em mulheres com disfonia comportamental. Delineamento do estudo: ensaio clínico, randomizado, controlado e cego. Método: participaram do estudo 22 mulheres (idades entre 18 e 45 anos) com diagnóstico de disfonia comportamental, alocadas de forma randomizada em dois grupos: Grupo Experimental (GE) ­ 11 mulheres que realizaram terapia vocal associada a aplicação do biofeedback eletromiográfico nos músculos esternocleidomastoideo e supra-hioideos; Grupo Placebo (GP) ­ 11 mulheres que realizaram terapia vocal associada a aplicação do biofeedback eletromiográfico placebo. Ambos os grupos realizaram 8 sessões de terapia, duas vezes por semana, com duração de 30 minutos. A terapia vocal de ambos os grupos foi composta por exercícios de trato vocal semiocluído (vibração, humming e fricativo). As avaliações foram realizadas em três momentos: antes, imediatamente após, depois de um e três meses da intervenção fonoaudiológica, e constaram de: avaliação vocal (perceptivo-auditiva e acústica), avaliação eletromiográfica de superfície, autoavaliação vocal, de sintomas vocais e laríngeos, da dor musculoesquelética e da qualidade de vida em voz. Os dados foram analisados estatisticamente, comparando-se os grupos e os momentos de avaliação (p=0,05). Resultados: A terapia vocal proposta promoveu resultados positivos na qualidade vocal, nos sintomas vocais, na qualidade de vida relacionada à voz e na atividade elétrica muscular durante o repouso em mulheres com disfonia comportamental, com ênfase nos aspectos fonatórios e comportamento vocal em nível glótico. Já o biofeedback eletromiográfico promoveu resultados positivos na atividade elétrica muscular durante as tarefas fonatórias e na dor musculoesquelética em mulheres com disfonia comportamental, com base nos aspectos comportamentais e musculares da região extrínseca da laringe, cintura escapular e cervical. Conclusão: Conclui-se que a terapia vocal associada ao biofeedback eletromiográfico tem efetividade equivalente e efeitos que se mantém pelo mesmo tempo na laringe, na voz e na autopercepção de sintomas e da qualidade de vida em voz, e é mais efetiva e tem efeitos que se mantêm por mais tempo na atividade elétrica muscular e na autopercepção da dor musculoesquelética de mulheres com disfonia comportamental do que a terapia vocal realizada de forma tradicional.(AU)

Introduction: dysphonia can affect the respiratory, glottic and ressonantal/articulatory levels, this limits the efficiency of communication and can cause quality of life damages. When the etiology of dysphonia is related to incorrect vocal use, it is classified as behavioral. Although the literature shows the effectiveness of several methods and programs of vocal rehabilitation, few investigate the self-perception and the participation of the body musculature in the dysphonia. In order to improve these issues, the literature proposed the electromyographic biofeedback. The studies that analyzed this method are remote and have methodological heterogeneity which makes it difficult to reproduce. Thus, it is necessary to analyze the effect of the method through a clinical trial to obtain scientific evidence on the intervention to support evidence-based clinical practice. Purpose: to analyze the effectiveness and duration of the effects of vocal therapy associated with electromyographic biofeedback in women with behavioral dysphonia. Study design: randomized controlled blinded clinical trial. Methods: Twenty-two women (18 to 45 years) with a diagnosis of behavioral dysphonia were randomly divided into two groups: Experimental Group (EG) - 11 women participated in vocal therapy associated with the application of electromyographic biofeedback of the sternocleidomastoid and supra-hyoids muscles; Placebo Group (GP) - 11 women participated in vocal therapy associated with the application of placebo electromyographic biofeedback. Both groups performed eight therapy sessions, twice a week, lasting 30 minutes. The vocal therapy of both groups was composed of semioccluded vocal tract exercises (trill, humming and fricative sounds). The evaluations were performed at four time points: before, after, one and three months after the vocal therapy and will consist of the assessments: vocal (auditory-perceptual and acoustic evaluation), surface electromyographic, vocal self-assessment, vocal and laryngeal symptoms, musculoskeletal pain and quality of life in voice. The data were analyzed statistically comparing the groups and the time of evaluation (p0.05). Results: The proposed vocal therapy promoted positive results in vocal quality, laryngeal and vocal symptoms, voice-related quality of life and muscular electrical activity during rest in women with behavioral dysphonia for both groups. Electromyographic biofeedback promoted additional positive results in muscle electrical activity during phonatory tasks and musculoskeletal pain in women with behavioral dysphonia. These results are based on the behavioral and muscular aspects of the extrinsic region of the larynx, scapular and cervical muscles. Conclusion: in this study, the vocal therapy associated with electromyographic biofeedback had equivalent efficacy to traditional therapy in the larynx, voice and self-assessment of symptoms and quality of life. The biofeedback was more effective than traditional therapy on muscular electrical activity and self-perception of musculoskeletal pain and had effects that remained for a longer time in women with behavioral dysphonia.(AU)

Musculoskeletal pain in children and adolescents

ABSTRACT Introduction Musculoskeletal (MSK) pain in children and adolescents is responsible for substantial personal impacts and societal costs, but it has not been intensively or systematically researched. This means our understanding of these conditions is limited, and healthcare professionals have little empirical evidence to underpin their clinical practice. In this article we summarise the state of the evidence concerning MSK pain in children and adolescents, and offer suggestions for future research. Results Rates of self-reported MSK pain in adolescents are similar to those in adult populations and they are typically higher in teenage girls than boys. Epidemiological research has identified conditions such as back and neck pain as major causes of disability in adolescents, and in up to a quarter of cases there are impacts on school or physical activities. A range of physical, psychological and social factors have been shown to be associated with MSK pain report, but the strength and direction of these relationships are unclear. There are few validated instruments available to quantify the nature and severity of MSK pain in children, but some show promise. Several national surveys have shown that adolescents with MSK pain commonly seek care and use medications for their condition. Some studies have revealed a link between MSK pain in adolescents and chronic pain in adults. Conclusion Musculoskeletal pain conditions are often recurrent in nature, occurring throughout the life-course. Attempts to understand these conditions at a time close to their initial onset may offer a better chance of developing effective prevention and treatment strategies.

The role of sensitization in musculoskeletal shoulder pain

Introduction: Peripheral and central sensitization are neurophysiological processes that can prolong painful conditions. Painful shoulder conditions are often persistent, perhaps due to the presence of sensitization.Method:This manuscript summarizes six studies that have evaluated those with musculoskeletal shoulder pain for the presence of sensitization.Results:All six manuscripts report evidence of peripheral sensitization, while central sensitization was described in five of the studies. The chronicity of symptoms in subjects who were included in the studies is probably influencing this finding. The primary somatosensory test used to assess sensitization in these studies was Pressure Pain Threshold, a test for lowered nociceptive thresholds.Discussion:It appears that peripheral sensitization manifests consistently in those with musculoskeletal shoulder pathology, probably due to the inflammatory processes related to tissue injury. Central sensitization, while not universally present, was reported in a majority of the manuscripts. Because central sensitization is thought to be a key step on the pathway to chronic pain, evidence for its presence in those with shoulder pain is significant. Clinicians should expect the presence of sensitization with shoulder pathology and make appropriate choices about interventions so as not to exacerbate pain.

Fibromyalgia and the old dilemma: theory vs. practice

The objective of this article is to review some aspects of the fibromyalgia syndrome and its mechanisms of development. We also discuss how to go from preclinical research to clinical practice. Fibromyalgia is a clinical syndrome whose main features include diffuse musculoskeletal pain, fatigue, sleep disturbances, and cognitive disorders. Russell & Larsson (2009) proposed "pronociceptive" and "antinociceptive" systems under normal conditions. Functional pain states such as fibromyalgia are derived from central disturbances in pain processing. The association with anxiety and depression is a negative prognostic factor. Distress is an important part of its physiopathology. The concomitance of other functional syndromes is a rule. The already known etiopathogenic mechanisms of fibromyalgia can be applied in clinical practice for diagnosis and rational therapeutic approaches. Pharmacological but mainly nonpharmacological measures must be applied. Although much information still needs to be obtained, the clinician presently has sufficient tools for efficiently treating fibromyalgia patients. An important aspect is that such knowledge needs to reach primary care physicians because the prevalence of fibromyalgia does not allow all patients to be treated by specialists.

Is painless synovitis different from painful synovitis? A controlled, ultrasound, radiographic, clinical trial

OBJECTIVE: This study compares the clinical, ultrasonography, radiography, and laboratory outcomes of painless and painful chronic synovitis in patients with established rheumatoid arthritis. METHODS: This cross-sectional study involved 60 patients with rheumatoid arthritis and synovitis in the metacarpophalangeal joints; 30 of the patients did not experience pain, and 30 had experienced pain for at least 6 months prior to the study. The radiocarpal, distal radioulnar, and metacarpophalangeal joints were evaluated using the ultrasound gray scale, power Doppler, and radiography. Past and present clinical and laboratory findings were also evaluated. RESULTS: There were no statistically significant differences between the groups for most of the outcomes. The group with pain scored worse on the disease activity indices (e.g., DAS 28 and SDAI), function questionnaires (HAQ and Cochin), and pinch strength test. A logistic regression analysis revealed that the use of an immunobiological agent was associated with a 3-fold greater chance of belonging to the group that experienced pain. The painless group had worse erosion scores in the second and fifth metacarpophalangeal with odd ratios (ORs) of 6.5 and 3.5, respectively. The painless group had more cartilage with grade 4 damage in the third metacarpophalangeal. CONCLUSIONS: The rheumatoid arthritis patients with both painless and painful synovitis exhibited similar disease histories and radiographic and ultrasound findings. However, the ultrasonography evaluation revealed worse scores in the second and fifth metacarpophalangeal of the synovitis patients who did not experience pain. .

Relationship of musculoskeletal pain with physical and functional variables and with postural changes in school children from 6 to 12 years of age / Relacao da dor musculoesqueletica com variaveis fisicas, funcionais e alteracoes posturais em escolares de seis a 12 anos

BACKGROUND: Painful disorders can affect children and adolescents, causing distress and significant demand for health services. OBJECTIVE: To identify the prevalence of musculoskeletal pain and its relation to age, sex, body mass index (BMI), how to carry school supplies, postures used in ADLs, outside school physical exercises and postural changes in students. METHOD: Cross-sectional exploratory study with a convenience sample consisted of 262 schoolchildren aged 6 to 12 years (137 female). Data collection was conducted by questionnaire containing personal data, presence and location of pain, means of transportation and illustrative figures for choosing the way of carrying school supplies and postures ADL's. Postural evaluation was performed by observational analysis and body mass index calculated from information on height, weight, age and sex. Descriptive analysis was carried out with numbers and percentages. For inferential statistics, comparison of average age according to the presence of pain was performed by Kruskal-Wallis with Dunn's post-test. Categorical variables were compared with chi-square test. RESULTS: The presence of musculoskeletal pain was reported by 51.1% of the students and 38.93% had pain in only one region. The most affected regions were legs, spine, arms and shoulders. The pain increased with age and with physical activity. CONCLUSIONS: In the our sample, 51.1% of students reported pain and 38.93% reported pain in only one region. There was no association between the presence of pain and sex, BMI, how to carry school supplies, postures used in ADLs and postural changes. The increasing age and physical exercise influenced significantly the presence of pain. .

OBJETIVO: Identificar a prevalência de dor musculoesquelética e sua relação com idade, sexo, Índice de massa corporal (IMC), forma de carregar o material escolar, posturas utilizadas nas atividades da vida diária (AVDs), realização de exercícios físicos orientados fora do ambiente escolar e alterações posturais. MÉTODO: Pesquisa de campo com delineamento transversal e caráter exploratório, com amostra de conveniência de 262 escolares de seis a 12 anos (137 mulheres), realizada com questionário contendo dados pessoais, presença e localização de dor, meio de locomoção, forma de carregar material escolar e posturas adotadas nas AVDs. A avaliação postural ocorreu por análise observacional. Na análise descritiva, usou-se números brutos e porcentagens. Na estatística inferencial, a comparação da idade segundo a presença de dor foi realizada pelo Teste de Kruskal-Wallis com pós-teste de Dunn. As variáveis categóricas foram comparadas pelo teste de qui-quadrado. RESULTADOS: A presença de dor musculoesquelética foi relatada por 51,1% dos escolares e 38,93% apresentaram dor em uma região. As regiões mais acometidas foram pernas, coluna, braços e ombros. Verificou-se que a dor aumentou com a idade e com a prática de atividade física. CONCLUSÕES: Na amostra, 51,1% dos estudantes relataram dor, sendo que 38,93% reportaram dor em somente uma região. Não houve associação entre presença de dor e sexo, IMC, forma de carregar o material escolar, posturas ...

Sleep, stress, neurocognitive profile and healthrelated quality of life in adolescents with idiopathic musculoskeletal pain

OBJECTIVES: The aims of this study were to measure levels of sleep, stress, and depression, as well as health-related quality of life, and to assess the neurocognitive profiles in a sample of adolescents with idiopathic musculoskeletal pain. METHODS: Nineteen adolescents with idiopathic musculoskeletal pain and 20 age-matched healthy control subjects were evaluated regarding their levels of sleep and stress, as well as quality of life, and underwent neurocognitive testing. RESULTS: The sample groups consisted predominantly of females (84%), and the socioeconomic status did not differ between the two groups. In addition, the occurrence of depressive symptoms was similar between the two groups; specifically, 26% of the idiopathic musculoskeletal pain patients and 30% of the control subjects had scores indicative of depression. Teenagers in the group with idiopathic musculoskeletal pain reported poorer quality of life and sleep scores than those in the control group. Regarding stress, patients had worse scores than the control group; whereas 79% of the adolescents with idiopathic musculoskeletal pain met the criteria for a diagnosis of stress, only 35% of the adolescents in the control group met the criteria. In both groups, we observed scores that classified adolescents as being in the resistance phase (intermediate) and exhaustion phase (pathological) of distress. However, the idiopathic musculoskeletal pain group more frequently reported symptomatic complaints of physical and emotional distress. The neurocognitive assessment showed no significant impairments in either group. CONCLUSION: Adolescents with idiopathic musculoskeletal pain did not exhibit cognitive impairments. However, adolescents with idiopathic musculoskeletal pain did experience intermediate to advanced psychological distress and lower health-related quality of life, which may increase their risk of cognitive dysfunction in the future.
