Indications All indications which require reinforcement and stabilization of physiological shoulder joint movement, such as: • Mild to middling instability of the shoulder joint • Conservative treatment the acute and habitual dislocated shoulder or subluxation • Second rehabilitation phase the operative therapy for shoulder Instability Mode of action • Individual adjustability of the belt system prevents shoulder from reaching vulnerable abducted, externally rotated position • Efficacy of glenohumeral-joint stability bracing is attributed to range-of-motion protection, allowing the dynamic-restraint system to react to sudden, forceful abduction and external forces before the shoulder reaches a vulnerable position of 90° of abduction.
