Efeitos do treinamento resistido nos músculos escapulares nas epicondilalgias: revisão sistemática e metanálise / Effects of resistant training on scapular muscles in epicondylalgia: systematic review and meta-analysis

As epicondilalgias medial e lateral são as causas mais frequentes de sintomas dolorosos nos membros superiores. Observa-se um aumento no número de publicações sobre os efeitos do treino da musculatura escapular no manejo clínico das epicondilalgias, porém desconhecemos uma revisão sistemática que avalie os efeitos do treinamento resistido nos músculos escapulares nessa condição. Objetivo: revisar sistematicamente os efeitos do treinamento resistido nos músculos escapulares nas epicondilalgias. Metodologia: foi realizada uma busca científica (SciELO, PubMed, LILASCS, PEDro) de estudos clínicos controlados sobre os efeitos do treinamento resistido nos músculos escapulares nas epicondilalgias publicados até maio 2021. A escala de PEDro foi aplicada para avaliação da qualidade metodológica. Resultados: foram encontrados 266 artigos e 3 foram incluídos na revisão sistemática. Os estudos inclusos enfatizaram o treinamento dos músculos trapézio médio, trapézio inferior e serrátil anterior associados a reabilitação convencional. Através da análise individual dos estudos observa-se efeitos positivos do treino escapular na dor, na função (Patient Rated Tennis Elbow Evaluation Questionnaire ­ PRTEE) e na força de preensão manual em indivíduos com epicondilalgias lateral. A metanálise revela que adicionar exercícios escapulares a fisioterapia convencional reduz a dor (EVA 0-10) em 1.23 (95% IC, 2,00-0,47, p=0,002, I2=47%, p para heterogeidade = 0.17) e aumenta a função (PRTEE 0-100) em 5.47 (95% IC, 10,00-0,93, p=0,02, I2=0%, p para heterogeidade = 0.84) na epicondilalgias lateral. A média de pontuação da escala PEDro foi de 6,33/10. Conclusão: o treinamento resistido dos músculos escapulares associados a reabilitação reduzem dor e aumentam função em indivíduos com epicondilalgia lateral. Sugere-se a realização de mais estudos com melhor qualidade metodológica para avaliar a importância do fortalecimento dos músculos escapulares em indivíduos com epicondilalgias. (AU)

Medial and lateral epicondylalgia are the most requente causes of painful symptoms in the upper limbs. There is na increase in the number of publications on the effects of scapular muscle training in the clinical management of epicondylalgia, but we do not know of a systematic review that assesses the effects of resistance training on scapular muscles in this condition. The aim of the study was to systematically review the effects of resistance training on scapular muscles in epicondylalgia. A scientific search (SciELO, PubMed, LILASCS, PEDro) of controlled clinical studies on the effects of resistance training for the scapular muscles in epicondylagias published until May 2021 was performed. The PEDro scale was applied to assess the methodological quality. 266 articles were found and 3 were included in the systematic review. The included studies emphasized the training of the middle trapezius, lower trapezius and serratus anterior muscles associated with conventional rehabilitation. Through the individual analysis of the studies, positive effects of scapula training on pain, function Patient Rated Tennis Elbow Evaluation Questionnaire ­ PRTEE) and handgrip strength were observed in individuals with lateral epicondylalgia. The meta-analysis reveals that adding scapular exercises to conventional physical therapy reduces pain (VAS 0-10) by 1.23 (95% CI, 2.00-0.47, p=0.002, I2=47%, p for heterogeneity = 0.17) and increases function (PRETEE 0-100) by 5.47 (95% CI, 10.00- 0.93, p=0.02 I2=0%, p for heterogeneity = 0.84) in lateral epicondylalgia. The average score of the studies on the PEDro scal e was 6.33 out 10. In conclusion, resistance training of scapular muscles associated with rehabilitation reduces pain the increases function in individuals with lateral apicondylalgia. It is suggested that more studies be carried out with better methodological quality to assess the importance of strengthening the scapular muscles in individuals with epicondylalgia. (AU)

Prevalence of Upper Extremity Musculoskeletal Diseases and Disability among Fruit Tree Farmers in Korea: Cross-Sectional Study

PURPOSE: The aim of this study was to examine the prevalence of upper extremity musculoskeletal (MSK) diseases and to identify factors influencing disability among fruit tree farmers in Korea. MATERIALS AND METHODS: Of the 1150 subjects of the Namgaram study, 460 fruit tree farmers completed a questionnaire and underwent clinical evaluations, including physical assessments, laboratory tests, simple radiographic examinations, and magnetic resonance imaging studies of the upper extremities. Disability was assessed using the Disabilities of the Arm, Shoulder, and Hand outcome measure. Data were analyzed with descriptive statistics and regression analyses using SPSS Win 24.0. RESULTS: The prevalences of upper extremity MSK diseases were 60.4% for rotator cuff tear, 20.9% for golf elbow, 40.9% for tennis elbow, and 58.0% for hand osteoarthritis. Disability in fruit farmers was associated with female sex (B=−4.47, p<0.001), smoking (B=−4.00, p=0.026), depression (B=2.83, p<0.001), working hours (B=0.96, p=0.001), injuries of the arms (B=10.78, p<0.001) and shoulders (B=6.75, p<0.001), and numbers of upper extremity MSK diseases (B=2.02, p=0.001), with 26.5% of the variance explained (R2=0.265, Durbin-Watson test=1.81, p<0.001). CONCLUSION: Fruit tree farmers remain at risk for MSK diseases of the upper extremities. Disability tended to worsen with more MSK diseases. It is necessary to not only educate farmers about prevention strategies, but also to develop an effective management system for agricultural work-related MSK diseases and a surveillance system at the government level for the health problems of farmers.

Association of lateral epicondylalgia and shoulder rotatory motion: A cross-sectional case control study

Background@#Lateral epicondylalgia (LE) is a cumulative strain injury affecting the common extensor origin of the elbow, manifesting as lateral elbow pain. Tightness of the fascia connecting the lateral elbow area with the shoulder area was assumed as potential source of LE. Limitation in shoulder rotatory motions may be associated with painful LE elbows.@*Aim@#To determine the difference on shoulder rotatory motions between sides of symptomatic and asymptomatic elbows.@*Methods@#Eligible participants had at least one elbow that tested positive for Cozen, Mill, or Maudsley’s test. Using a universal goniometer, a blinded assessor measured the participants’ active and followed by passive shoulder internal and external rotation. The primary investigator tested the external rotation followed by internal rotation of the right upper extremity, then subsequently the left upper extremity of healthy participants both passively and actively@*Results@#The assessor showed excellent intra-tester reliability in measuring active and passive shoulder rotatory motions of 20 asymptomatic right upper extremities (ICC=0.98). Twenty-seven (27) participants (3 males, 24 females) with a mean (95%CI) age of 54 (49-58) years old were enrolled in the study. The mean visual analogue scale of the patients was 6.53 (5.91- 7.13), with mean (95%CI) duration of 96 (50-142) weeks. Based on hand dominance and side of LE, significant difference was found in active and passive shoulder internal rotation (p>0.05). @*Conclusion@#Shoulder active and passive internal rotations were significantly associated with hand dominance in patients with LE. Tightness of the fascia and muscle in the shoulder and painful LE elbow may underpin the decreased shoulder rotatory motions.

Terapia de ondas de choque en patología músculo-esquelética / Pathology shock wave therapy muscle-skeletal

Extracorporeal shock waves are unique sound waves that generate a rapid increase in pressure in the tissues in which they are applied. They were first used on the management of urolithiasis and later spread to other pathologies such as musculoskeletal. A series of studies have been carried out to support the usefulness of shock waves in patients with plantar fasciitis, Achilles tendinopathy, epicondylitis, rotator cuff injury with or without calcification, patellar tendinopathy and peritrochanteric pathology that has lasted more than three months and have not responded to the initial handling. There is no consensus regarding the specific protocols to be used. In these conditions, shock waves are only a part of a comprehensive treatment, and should always be associated with other conventional therapies. (AU)

Arthroscopic surgical treatment of recalcitrant lateral epicondylitis - A series of 47 cases / Tratamento cirúrgico artroscópico da epicondilite lateral recalcitrante - Série de 47 casos

ABSTRACT OBJECTIVE: To evaluate the results of patients undergoing arthroscopic surgical treatment of refractory lateral epicondylitis, identifying poor prognosis factors. METHODS: A retrospective study of 44 patients (47 elbows) who underwent arthroscopic debridement of the extensor carpi radialis brevis (ECRB) tendon to treat refractory lateral epicondylitis from February 2013 to February 2015, operated by a single surgeon at one center. Patients were assessed by DASH score, visual analog scale of pain (VAS), and ShortForm 36 (SF-36). The mean age at surgery was 44.4 years (32-60). The duration of symptoms prior to the surgery was approximately 2.02 years (range: 6 months to 10 years). Mean follow-up was 18.6 months (range of 6-31.9) . RESULTS: The mean postoperative DASH score was 25.9 points; mean VAS, 1.0 point at rest (all the patients with mild pain) and 3.0 points at activity, of which 31 (66%) cases presented mild pain, 10 (21%) moderate pain, and six (13%) severe pain; mean SF-36 score was 62.5. A moderate correlation was observed between duration of pain before surgery and the DASH score with the final functional outcome. No significant complications with the arthroscopic procedure were observed. CONCLUSIONS: Arthroscopic surgical treatment for recalcitrant lateral elbow epicondylitis presented good results, being effective and safe. The shorter the time of pain before surgery and the lower the preoperative DASH score, the better the prognosis.

Preliminary Clinical Results of Topaz Microdebridement Procedure in Lateral Epicondylitis Patients / 대한스포츠의학회지

The purpose of this study is to clinically evaluate and report the effectiveness of radiofrequency microdebrider (Topaz, ArthroCare) treatment in lateral epicondylitis patients. From March to July 2003, 15 patients of 17 elbows were prospectively followed. Candidate for the treatment were lateral epicondylitis patients who had symptom more than 6 month and failed to respond to conservative treatment, including medication (non-steroidal anti-inflammatory drugs), external gel or patch, and steroid injections. All patient who scored greater than grade 3 (fair) on the Self-administered Roles and Maudsley Pain (SRMP) score were selected for the procedure. All procedure was done using local anesthesia and ArthroCare microdebrider by a single surgeon. Postoperative assessments were done on postoperative period 12 month of two previous subjective scores and a simple functional assessment asking better, same, or worst function after the procedure. Mean age of the patients was 45 years old. Mean symptom duration before the procedure was 22.6 months. After the procedure, the mean Pain Visual Analogue Scale improved from 7.3 (range, 5–9; standard deviation [SD], 1.2) preoperatively to 3.7 (range, 0–7; SD, 2.1) postoperatively (p< 0.001). After the procedure, five elbows showed no rating improvement, in seven elbows 1 level improvement, in four elbows 2 level improvement, and in one elbow 3 level improvement. Overall, 71% (12/17) showed improvement after the procedure according to the SRMP score rating. Although 29% (5/17) of the elbow showed no improvement on SRMP score, among them five elbows were still rated decrease in Pain Visual Analogue Scale.

Recent Updates on the Treatment of Lateral Epicondylitis

The natural course of lateral epicondylitis is widely regarded to be self-limiting within 1 year of symptom duration in 90% of all patients. The spectrum of treatments include simple ‘wait and see', bracing, physical therapy, corticosteroid injection, and recently some biologic injection such as autologous blood and platelet rich plasma. However, recalcitrant lateral epicondylitis which are not responding to conservative treatments can be treated with surgical treatment although much remains unclear regarding the ideal treatment. Debates surrounding open procedures are the management for the defect after resection of pathologic tissue, necessity of decortication, selective denervation procedure, etc. Since the trend is changing to minimal invasive surgery and arthroscopic release of extensor carpi radialis brevis tendon are becoming more popular these days, surgical tips and pitfall to obtain good results and avoid complications have been reported recently. Bipolar radiofrequency (RF)-based microtenotomy or percutaneous tendon release is another surgical procedures reported to be effective in lateral epicondylitis. However, there are some patients who present with persistent pain after surgical treatment. Thus, selection of ideal candidates for surgery, thorough evaluation of all pathologies prior to surgery, and adequate surgical procedures would be essential in the surgical treatment of lateral epicondylitis.

Effects of platelet-rich plasma on lateral epicondylitis of the elbow: prospective randomized controlled trial / Efeitos do plasma rico em plaquetas na epicondilite lateral do cotovelo: estudo prospectivo, randomizado e controlado

To evaluate the effects of platelet-rich plasma (PRP) infiltration in patients with lateral epicondylitis of the elbow, through analysis of the Disabilities of the Arm, Shoulder and Hand (DASH) and Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaires. METHODS: Sixty patients with lateral epicondylitis of the elbow were prospectively randomized and evaluated after receiving infiltration of three milliliters of PRP, or 0.5% neocaine, or dexamethasone. For the scoring process, the patients were asked to fill out the DASH and PRTEE questionnaires on three occasions: on the day of infiltration and 90 and 180 days afterwards. RESULTS: Around 81.7% of the patients who underwent the treatment presented some improvement of the symptoms. The statistical tests showed that there was evidence that the cure rate was unrelated to the substance applied (p = 0.62). There was also intersection between the confidence intervals of each group, thus demonstrating that the proportions of patients whose symptoms improved were similar in all the groups. CONCLUSION: At a significance level of 5%, there was no evidence that one treatment was more effective than another, when assessed using the DASH and PRTEE questionnaires.

MÉTODOS: Foram randomizados e avaliados prospectivamente 60 pacientes, após receberem infiltrações de três mililitros de PRP, ou neocaína 0,5%, ou dexametasona. Para o processo de pontuação, os pacientes foram convidados a preencher os questionários Dash e PRTEE em três ocasiões: no dia da infiltração, 90 e 180 dias após. RESULTADOS: Dos pacientes submetidos ao tratamento, 81,7% apresentaram melhoria dos sintomas. Os testes estatísticos demonstraram que há evidências de que a taxa de cura não está relacionada com a substância aplicada (p = 0,62). Houve também interseção dos intervalos de confiança de cada grupo, com demonstração de que as proporções de pacientes cujos sintomas melhoraram foram semelhantes em todos os grupos. CONCLUSÃO: Em um nível de significância de 5%, não houve evidência de que um tratamento foi mais eficaz do que a outro, quando avaliados pelos questionários Dash e PRTEE.

Lateral epicondylitis is a common cause of pain and functional impairment of the elbow. Usually is due to the repetition not only of certain sporting gestures but also of repetitive working activities. The vast majority of cases resolve through nonsurgical treatments. The surgical treatment of recalcitrant lateral epicondylitis has shown satisfactory results through open, percutaneous and arthroscopic procedures, with no consensus on the best surgical therapy for the disease yet. This technical note describes the arthroscopic procedure of tenotomy of the extensor carpi radials brevis and lateral capsulotomy of the elbow both using scalpel blade in a patient with recalcitrant epicondylitis.

Tratamiento de epicondilitis de codo con plasma rico en plaquetas versus corticosteroide local / Treatment of elbow epicondylitis with platelet rich plasma versus local corticosteroids

Antecedentes: La epicondilitis es una patología con una alta frecuencia en la población mexicana, estudios recientes refieren buenos resultados con plasma rico en plaquetas. Sin embargo, el tratamiento más comúnmente usado en México es la aplicación de corticoesteroide. Objetivo: Realizar en estudio comparativo en donde se determine qué tratamiento tiene mejores resultados (plasma rico en plaquetas vs corticoesteroide). Material y métodos: Se conformaron dos grupos de personas aleatorizadas haciendo dos grupos, el grupo A fue tratado con una sola aplicación de plasma rico en plaquetas y el grupo B fue tratado con 40 mg de metil prednisolona, dosis única. Se realizó una evaluación con la escala visual análoga y con la escala Quick DASH, dicha prueba fue aplicada previo al procedimiento, al mes, a los tres y seis meses. Resultados: Los resultados fueron comparados con un análisis de t de Student. Al mes de la evaluación, los pacientes muestran mejoría sin diferencia significativa. A los tres meses, el plasma rico en plaquetas muestra mejores resultados; sin embargo, a los seis meses se ve un discreto decremento de ésta. Conclusiones: De acuerdo con los resultados obtenidos, el plasma rico en plaquetas muestra mejores resultados en cuanto mejoría del dolor y duración del tratamiento; sin embargo, aún está pendiente definir el número de aplicaciones, así como la posibilidad de obtener mejores resultados al acompañarlo de rehabilitación.

Background: Epicondylitis is a highly frequent condition in the Mexican population. Recent studies have reported good results with platelet rich plasma. However, corticosteroids are the most common treatment used in Mexico. Objective: To conduct a comparative study to determine which treatment provides better results (platelet rich plasma versus corticosteroids). Material and methods: Patients were randomized into two groups. Group A was treated with a single administration of platelet rich plasma and group B with a single dose of 40 mg of methylprednisolone. Patients were assessed using a visual analog scale (VAS) and the Quick DASH scale, applied before the procedure, and at one, three and six months. Results: The results were compared with an analysis using the Student t test. One month after treatment the patients had improvement with no significant difference between both groups. At three months results were better with platelet rich plasma; however, at six months improvement with the latter declined slightly. Conclusions: The results show that platelet rich plasma provided better results from the perspective of pain control and effect duration. However, the number of applications and the possibility of improving the outcomes if combined with rehabilitation have not yet been determined.

Efectividad de la acupuntura con tachuela en afectados por epicondilitis / Effectiveness of acupuncture with tacks in affected patients with epicondilytis

Se realizó una intervención terapéutica en 20 pacientes con epicondilitis, remitidos de la consulta de Ortopedia al Departamento de Medicina Natural Tradicional del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, de septiembre a diciembre de 2012, con vistas a determinar la efectividad de la acupuntura con tachuela en ellos. Los afectados fueron valorados y, de forma aleatoria, se les distribuyó en 2 grupos de 10 integrantes cada uno: el de estudio, que recibió acupuntura (agujas de 0,2 mm) de forma permanente en los puntos Ashi y en el IG-11, y el de control, tratado convencionalmente con antiinflamatorios y analgésicos. Luego de aplicadas las terapias, los pacientes fueron valorados a los 5, 10 y 15 días, teniendo en cuenta el cuadro clínico dado por dolor, inflamación e impotencia funcional. La regresión de los síntomas se evaluó por la escala visual analógica, y se obtuvo una efectividad marcada del tratamiento con acupuntura en relación con el medicamentoso.

A therapeutic intervention in 20 patients with epicondilytis, transferred from the Orthopedics Department to the Traditional Natural Medicine Department from "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba was carried out from September to December of 2012, aimed at determining the effectiveness of the acupuncture with tacks in them. Those affected were evaluated and, were randomly distributed into 2 groups of 10 members each: the study group which received acupuncture (needles of 0.2 mm) in a permanent way in the points Ashi and in the IG-11, and the control group, conventionally treated with anti-inflammatory and analgesic drugs. After the therapies were applied, patients were evaluated after 5, 10 and 15 days, keeping in mind the clinical pattern manifested by pain, inflammation and functional impotence. The regression of the symptoms was evaluated by the analogical visual scale, and a marked effectiveness of the treatment was obtained with acupuncture in relation to the drug treatment.

Case-control study on local injection of autoallergic platelet rich plasma or whole blood for the treatment of tennis elbow / 中国骨伤

<p><b>OBJECTIVE</b>To compare therapeutic effects of local injection with autoallergic platelet rich plasma (PRP) or autoallergic whole blood (AWB) for the treatment of chronic tennis elbow.</p><p><b>METHODS</b>From January 2011 to January 2014, 40 patients with chronic tennis elbow were divided into 2 groups, 20 cases in each group: PRP group and AWB group. There were 20 patients in PRP group treated with local injection of autoallergic platelet rich plasma, including 5 males and 15 females, with an average age of (47.50 ± 9.86) years old; and the average course of disease was (4.67 ± 3.27) months. Among the 20 patients in AWB group treated with local injection of autoallergic whole blood, 3 patients were male and 17 patients were female, with an average age of (46.50 ± 9.96) years old;and the average course of disease was (4.53 ± 2.27) months. The elbow joint was fixed with elastic stockings after injection. All the patients were guided to do strengthening and extension exercises during the follow-up period. Visual analog scale (VAS), Mayo scores for elbow and pressure pain threshold (PPT) were used to evaluate clinical effects after injection immediately and 4,8 weeks after treatment. Results:All the patients were followed up,there were no infections and swelling occurred. The VAS, Mayo and PPT scores of patients in PRP group were improved from pre-therapy 7.22 ± 1.32, 56.71 ± 10.90 and 17.47 ± 4.62 to 2.73 ± 1.00, 91.59 ± 6.95 and 21.35 ± 4.80 respectively 8 weeks after treatment. The VAS, Mayo and PPT scores of patients in AWB group were improved from pre-therapy 7.16 ±1.27, 54.72 ± 8.36 and 17.06 ± 4.83 to 3.81 ± 1.36, 82.06 ± 7.89 and 20.12 ± 4.97 respectively 8 weeks after treatment. All the pain and functional variables including VAS, PPT, and Mayo scores were improved significantly in both groups 4 weeks after injection. On the 4th week after injection, there was no statistically significant difference in PPT between two groups; while the VAS and Mayo score of AWB group were lower than those of PRP group. On the 8th week after injection, the VAS of AWB group was higher than that of PRP group; but the Mayo and PPT scores of AWB group were lower than those of PRP group.</p><p><b>CONCLUSION</b>PRP and AWB injections are both effective to treat chronic lateral epicondylitis. Compared with AWB injection, PRP injection may be more effective in releasing pain and improving function for a longer time.</p>
