THE AIM OF THE INVESTIGATION WAS TO 1) compare shoulder external/internal rotator muscles' peak torques and average power values and their ratios in the dominant and non-dominant arm; 2) determine correlations between shoulder rotator muscles' peak torques, average power and ball-throwing speed in handball players. Fourteen 14 to 15-year-old male athletes with injury-free shoulders participated...

background: lateral epicondylitis, also known as tennis elbow, is the most common overuse syndrome of the elbow. the severity of pain may not be directly caused by tendinopathy of wrist extensors since trigger points of the shoulder muscles have a referral zone in the arm and elbow. therefore the aim of this study was to evaluate the effect of dry needling of shoulder myofascial trigger points ...

QUESTION During isometric shoulder adduction in normal subjects, do the rotator cuff muscles activate more than other shoulder muscles? Are the activation patterns influenced by shoulder abduction angle or load? DESIGN A within-participant, repeated measures experimental study. PARTICIPANTS 15 healthy adults. INTERVENTION Participants performed an isometric adduction exercise at 30°, 60°,...

Overhead athletes including those in racket sports, throwers, volleyball players, and swimmers require full, unrestricted use of their upper extremity to compete at optimal levels. Scapulothoracic and scapulohumeral (rotatorcuff) muscle function are critical for normal overhead activities of the shoulder and play an important role in normal shoulder function. Furthermore, weakness of scapulotho...

OBJECTIVE The aim of this study was to investigate differences in muscle stiffness between subjects with stiff shoulders and controls, and to determine the correlation between posterior shoulder muscle stiffness and range of motion of rotation. DESIGN Prospective, cross-sectional study. SUBJECTS Twenty subjects with stiff shoulder and 20 healthy subjects. METHODS Range of motion of rotati...

[Purpose] This study investigated the effect of shoulder girdle strengthening, particularly the scapular muscles, on poststroke trunk alignment. [Subjects and Methods] The study involved 30 patients with residual hemiparesis following cerebrovascular stroke. Patient assessment included measuring shoulder muscle peak torque, scapular muscles peak force, spinal lateral deviation angle, and motor ...

BACKGROUND Sympathetic nervous activity contributes to the maintenance of muscle oxygenation. However, patients with chronic pain may suffer from autonomic dysfunction. Furthermore, insufficient muscle oxygenation is observed among workers with chronic neck and shoulder pain. The aim of our study was to investigate how muscle load tasks affect sympathetic nervous activity and changes in oxygena...
