🔈 MUSCLE ENERGY TECHNIQUE – SUBSCAPULARIS ANATOMY Origin: Subscapular fossa of the scapula Insertion: Lesser tubercle of the humerus Action: medial rotation of shoulder, stabilize the head of humerus in glenoid cavity ASSESSMENT OF SUBSCAPULARIS The therapist takes the patient's arm to 90 degrees of abduction and 90 degrees of elbow flexion – an assessment in this position in known as the 90/90 test. From this position, the therapist supports the patient's elbow with their right hand and the patient's forearm with their left hand. The therapist then takes the patient's arm into external rotation until a bind is felt. For normal range of motion of the subscapularis, the external rotation should achieve 90 degrees, i.e. the patient's forearm should be parallel to the couch. If there is shortness of the subscapularis, the range of motion will be less than 90 degrees. MET TREATMENT OF SUBSCAPULARIS PIR METHOD The therapist takes the patient's shoulder into external rotation until a bind is felt. From the position of bind, the patient is asked to contract the subscapualris by internally rotating their shoulder. After 10 seconds and on the relaxation phase, the therapist applies traction to the shoulder joint (to prevent an impingement) and slowly encourages the shoulder into further external rotation. RI METHOD If the patient has discomfort activating the subscapularis, the antagonistic muscle of the infraspinatus can be activated instead. From the position of bind, the patient is asked to resist external rotation: this will contract the infraspinatus and allow the subscapularis to relax through RI. On the relaxation phase, a lengthening procedure of the subscapularis can then be performed. 🔑 The subscapularis is one of the rotator cuff muscles and is the main medial rotator of the glenohumeral joint. A subscapularis strain can result in referred pain to the area of the deltoid tuberosity. Best Physiotherapy Clinic in nallasopara
