Shoulder muscle function in frozen shoulder syndrome

SpletElectromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle. Splet03. apr. 2024 · The aim of this study was to access the electromyographic (EMG) activity within SSP, deltoid, and surrounding periscapular muscles after resisted abduction force to determine which shoulder position helps best isolate SSP from deltoid activity. Methods: A controlled laboratory EMG study was conducted. Specifically, we conducted an EMG …

SpletFor the EMG a multivariate linear mixed model was used to compare groups on concentric and eccentric deltoid muscle output by activity performed. For the mixed models fixed effects included shoulder and group, and an unstructured covariance matrix was used for the random effects to model the correlation among outcomes measures. SpletIntroduction. Examining patients with shoulder problems can be challenging because (1) shoulder motion involves a complex interaction of movement of the scapula on the thorax, the humeral head on the glenoid, and the clavicle at the acromioclavicular and sternoclavicular joints [6, 13, 24]; and (2) physical examination tests for the shoulder are …

SpletStudy design: Laboratory design using healthy subjects. Methods: Eight healthy subjects (16 shoulders) (5 females, 3 males; avg. age 29.2) were tested.
