The handheld dynamometer is a portable device of easy use in clinical practice. However, its use requires reliability and reproducibility parameters in shoulder positions with and without stabilization. The objective of this study was to evaluate the inter- and intra-examiner reliability of the shoulder rotator strength measurement at 0° and 90° abduction with inexperienced examiners. Twenty subjects (27.05 ± 8.17 years, 76.6 ± 10.97 kg, 1.74 ± 0.07 m) of both sexes and no previous or current complaints of shoulder and neck pain participated in this study. The evaluation of the internal and external shoulder rotators was performed using a handheld dynamometer (MicroFET 2, Hoogan Health Industries, West Jordan, UT, USA) in two positions: sitting with 0° shoulder abduction and supine and with 90° shoulder abduction. Inter- and intra-examiner reliability and reproducibility were assessed through the intraclass correlation coefficient (ICC) considering a 95% confidence interval (p

A dor no ombro representa a terceira principal queixa musculoesquelética da população. Afeta fatores físicos, psicológicos e econômicos do indivíduo. A atenção primária à saúde é essencial para a eficácia do cuidado dos pacientes acometidos. Este estudo é observacional transversal e obteve um perfil dos usuários e das consultas médicas com relato de dor no ombro durante um ano na atenção primária do município de Ribeirão Preto (SP). Foram analisados em prontuários os registros das consultas médicas agendadas e sem agendamento prévio. Nestes registros foram coletados dados dos pacientes que apresentaram queixas de dor musculoesquelética no ombro (dados sociodemográficos e características das consultas), que foram analisados de forma descritiva e pelos testes qui-quadrado de Pearson, razão de chance e regressão logística múltipla. A frequência de consultas médicas por queixa de dor no ombro foi de 9,2%. O perfil dos indivíduos que se queixaram de dor no ombro se caracterizava por mulheres, com idade avançada, casadas, alfabetizadas e que apresentavam alguma ocupação. As consultas em sua maioria tiveram retornos agendados, oferecimento de orientações terapêuticas e poucos encaminhamentos.

En la artrocinemática del hombro, el manguito rotador actúa estabilizando la cabeza umeral en contacto a la cavidad glenoidal, mientras realiza la traslación inferior para contrarrestar la fuerza rotacional promovida principalmente por el deltoides. Los ejercicios de rotación externa (RE) se han utilizado en la rehabilitación de pacientes con disfunciones en el complejo del hombro buscando restaurar la artrocinemática. Pocos estudios abordan la utilización de la banda elástica y la evaluación de los músculos de la cintura escapular, determinantes para una cinemática adecuada. El objetivo de este estudio es comparar la actividad electromiográfica (EMG) de los músculos del complejo del hombro durante ejercicios de rotación externa con banda elástica. Participaron 11 sujetos, varones, que fueron evaluados durante el movimiento de (1) RE en ortostasis; (2) RE con abducción de hombro; y (3) RE en decúbito lateral (DL). Los músculos evaluados por la EMG fueron: (a) trapecio superior (TS); (b) deltoides central (DC); (c) deltoides posterior (DP) e (d) infraespinoso (IN). La resistencia se determinó mediante una banda elástica gris calibrada con carga del 5% del peso corporal. El análisis de los datos se realizó con la utilización del software BIOMEC-SAS, y las estadísticas por medio de la ANOVA de medidas repetidas en el software SPSS v20.0. Se pudo constatar que los músculos TS y DC obtuvieron mayor actividad EMG durante el ejercicio de RE con abducción de hombro, el músculo DP durante la RE con abducción de hombro y RE en decúbito lateral, mientras que el IN durante la RE en ortostasis y en decúbito lateral.

El dolor musculoesquelético en el hombro es una de las causas más frecuentes de dolor y discapacidad en adultos. El presente artículo tuvo el objetivo de verificar la prevalencia de dolor de hombro y factores correlacionados en adultos mayores de 20 años. Estudio transversal con 600 individuos entrevistados mediante cuestionarios que han identificado: (1) caracterización de los participantes; (2) nivel de actividad física; (3) morbilidades reportadas; y (4) síntomas musculoesqueléticos. Se realizaron análisis descriptivos, bivariados y de Poisson. La prevalencia del dolor de hombro fue del 24% (IC 20,3%-27,5%). Los indicadores de dolor del hombro fueron: tener 60 años o más (PR=2.14; 1.33-2.45); ser mujer (PR=1.92; 1.29-285); usar la computadora más de tres veces por semana (PR=1.55; 1.01-2.32); trabajar en una posición sentada (PR=1.64; 1.03-2.59); trabajar de pie inclinando el cuerpo hacia adelante (PR=1.54; 1.00-2.37); e informar dos o más morbilidades (PR=3.31; 1.97-5.57). El estudio reveló una alta prevalencia de dolor en el hombro y una fuerte relación con ser mujer, mayor de 60 años, usar la computadora más de tres veces por semana, realizar actividades ocupacionales sentado o de pie inclinándose hacia adelante, e informar la existencia de dos o más enfermedades.

El movimiento del remo representa el 51,4% del tiempo total de práctica de surf, generando una alta demanda muscular del complejo del hombro. Sin embargo, existe una brecha en la literatura sobre la prevalencia del dolor y la discinese escapular (DE) en los surfistas. Este estudio tuvo como objetivo evaluar la prevalencia de DE y dolor de hombro en surfistas aficionados del estado de Rio Grande do Sul, Brasil. Estudio observacional descriptivo transversal. Se incluyeron 21 hombres de 18 a 42 años que habían surfeando durante al menos 2 años. Los resultados evaluados fueron DE estática, DE dinámica, dolor de hombro usando la escala numérica de dolor, longitud del pectoral menor y puntaje en The Western Ontario Shoulder Instability Index. Las variables continuas se presentaron como media y desviación estándar. Las variables categóricas se expresaron como porcentaje. Las asociaciones de datos se probaron utilizando la Prueba Chi-cuadrado y el Coeficiente de Correlación de Pearson. La DE estaba presente en el 71,4% de la muestra, con una mayor prevalencia de discinesia tipo I (57,1%) y el 42,9% tenía dolor de hombro durante la evaluación. DE se observó en la mayoría de la población de estudio, mientras que el dolor en poco menos de la mitad de los participantes. Aunque el DE es un hallazgo muy frecuente en los surfistas, no hubo correlación con el dolor y la reducción de la calidad de vida.

Factors such as schooling level, age and gender are associated with a more intense pain and a higher level of dysfunction in the shoulder and self-efficacy can modify the effect that pain and dysfunction have on patients’ clinical outcomes. Our study investigated if the score on the Shoulder Pain and Disability Index (SPADI), age, schooling level and gender are predictive of self-efficacy in patients with shoulder pain. It also verified if there are differences in levels of pain and disability between age groups and genders. Sociodemographic data and scores from the SPADI and the Chronic Pain Self-Efficacy Scale (CPSS) from a database of patients treated at a public physical therapy clinic specialized in shoulder were analyzed. In total, 123 patients with a mean age of 54 (±11.54), SPADI of 67.56 (±22.54) and CPSS of 182.22 (±61.76) were analyzed. Multiple linear regression analysis showed SPADI as the only predictive factor of self-efficacy (β=-1.39 [95%CI=-1.84 to -0.93], p<0.001), explaining 23% of its variance (r2=0.23). ANOVA showed that the SPADI score was significantly different between genders (mean difference=22.27; p<0.001), but was similar between age groups (mean difference=7.04, p=0.16). We concluded that patients that complained of shoulder pain in a public shoulder physical therapy clinic were middle-aged women, who attended only up to middle school, had significant pain and disability, and high self-efficacy. The SPADI score can partially predict self-efficacy.

The purpose of the study was to assess whether there is a relation between shoulder functional capacity and occupational activity among traffic workers exposed to repetitive movements and/or to overexertion; and to inquire on shoulder complaints and symptoms of cumulative trauma disorders. A hundred and two traffic workers were divided into two groups - G1 exposed to overuse and overexertion, G2 exposed only to overuse - and submitted to the Constant-Murley functional shoulder protocol, which assesses four items: pain, pain in activities of daily living, range of motion, and muscle strength. Data were statistically analysed and significance level set at p

Breast cancer is the most frequent neoplasm among women; it is traditionally treated by surgery ranging from quadrantectomy to widened modified radical mastectomy, of which common sequels are changes in articular range of motion, muscle strength decrease, lymphedema, and adherences. The aim of this work is to evaluate shoulder motion range and muscle strength in late post-operative patients having undergone radical modified mastectomy. Nine women, mean aged 53.22±6,5 years, in 2-to-7 year post-operative span, were evaluated as to shoulder motion range and muscle strength of the surgery side, considering the contralateral shoulder and limb as the standard reference for comparison. Data were statistically analysed and significance level set at p=0.05. Results showed significant reduction in shoulder range of motion in all patients, mainly in active and passive flexion and abduction, as well as lesser muscle strength, especially in Middle Trapezius and Supraspinatus muscles, as compared to the healthy limb. Findings stress the need to physical therapy to be onset at immediate post-operative, in order to minimize possible sequels and improve women's quality of life.

Patients with chronic obstructive pulmonary disease (COPD) often complain about difficulties in performing activities with their arms above shoulders height. These difficulties have been associated with increased cardiorespiratory demand and altered lung mechanics; however, musculoskeletal-related mechanisms may also contribute to constrain the mechanics of the upper body quadrant, increasing the effort to perform the activities. This exploratory research aimed to assess potential changes in the kinematic chain of arm elevation in patients with COPD. A secondary analysis from a cross-sectional exploratory case-control and prediction study was conducted in 15 patients with COPD (2 females) and 15 controls (8 females) matched for age and body mass index. The sagittal alignment and active range of motion (ROM) of the head, thoracic spine and shoulder complex were measured, using a computer software, in digital lateral photographs obtained in three different testing positions: arms at rest, arms at 90° of shoulder flexion and full arm elevation. From rest to full arm elevation, both groups moved from a more flexed to a less flexed or more upright thoracic spine position (∼7°, p < 0.001, 0.419 < ηp2 <0.767). However, the COPD group showed significantly less shoulder flexion (∼12°, p = 0.007, d = 1.05) and thoracic spine extension (∼6°, p = 0.015, ηp2 = 0.139) ROM than the control group in the full arm elevation position. These findings suggest that this population may show changes in the kinematic chain of arm elevation that possibly contribute to arm movement-related complains and limited performance in their daily living.
