“…A study by Gordon and colleagues of EMG signal during supination and pronation [ 22 ] suggests that the pronator teres muscle is the primary agonist during resisted pronation (as in these patients: the early recovery of biceps supination power). The net result is development of supination deformities due to relative pronation weakness with excessive supinator and biceps muscle activity [ 23 , 24 ].…”

Background: Patients who have suffered obstetric brachial plexus injury (OBPI) have a high incidence of musculoskeletal complications stemming from the initial nerve injury. The presence of muscle imbalances and contractures leads to typical bony changes affecting the shoulder, including the SHEAR (Scapular Hypoplasia, Elevation and Rotation) deformity. The SHEAR deformity commonly occurs in conjunction with Medial Rotation Contracture (MRC) of the arm. OBPI also causes muscle imbalances at the level of the forearm, that lead to a fixed supination deformity (SD) in a small number of patients. Both MRC and SD will cause severe functional limitations without surgical intervention.
