Scapulothoracic elevation

WebOct 29, 2012 · Arm elevation is composed of glenohumeral (GH) and scapulothoracic (ST) joint motion. This was first called scapulohumeral rhythm (SHR) by Codman[] and the normal ratio was reported by Inman et al.[] as 2:1 (Figure1).The motion of the scapula is affected by GH joint motion, and according to Inman, the setting phase is in 0 to 60 degrees of … WebScapulothoracic joint is not a true synovial joint. Scapulothoracic motion produces a snapping, popping, crepitus sound.

WebShoulder elevation led to higher activity of the upper trapezius and middle deltoid. Moreover, it induced lower activation of the serratus anterior and middle and lower trapezius, thus leading to high ratios between the upper trapezius and the other scapulothoracic muscles, especially between 15 and 75 degrees of abduction. WebMethods: Activity of the deeper lying (LS, Pm and RM) and superficial lying scapulothoracic muscles (Trapezius and SA) was investigated with fine-wire and surface electromyography (EMG) in 17 subjects with SIS and 20 healthy subjects while performing 3 elevation tasks: scaption, wall slide and elevation with external rotation.
