Pectoralis major is the muscle which acts as prime mover in shoulder flexion.The biceps brachii assist this movement. peroneus tertis, peroneus longus Middle and lower fibers: they contribute with serratus anterior to rotate scapula upward, externally rotate the scapula through their torque on AC joint and have a retractor force on scapula that force offsets the protraction of SA muscle. Chapter 1. This may be due to a mechanical disadvantage because the elbows tend to move more laterally through the sticking point (Gomo & Van den Tilaar, 2015).

Trapezius (lower) Erector spinae spinalis adductor mangus > Lower the barbell toward your chest, by flexing your elbows while maintaining scapulae retraction. . Wilk KE, Yenchak AJ, Arrigo CA, Andrews JR. Both antagonist and agonist muscles are used for stabilization. Because the scapulothoracic joint is a floating joint, it solely relies on neuromuscular control (adequate strength and control of the stabilizer muscles, as well as a healthy sense of muscular timing). infraspinatus The Peripheral Nervous System, Chapter 18. Muscle pull rather than push. Clavicle retraction contributes to 100% of scapular external and the clavicle elevation contributes to about 75% of scapular anterior tilt and 25% of scapular upward rotation of the scapula.

Active: Joint motion due to muscle contraction (done by the patient). Reeducation of the rotator cuff muscles (working in rotations at various angles of elevation, scaption movements and functional activities). In addition, this position may be less aggravating for people with a history of shoulder pain because the eccentric phase requires less shoulder horizontal abduction and places a greater emphasis on sagittal plane shoulder extension.
