A shoulder and arm support for supporting either the left or right shoulder and arm of a patient. The support includes a case, a removable support member, and a sling which houses a shoulder strap secured thereto and a body strap secured thereto. The case houses an interior compartment in which a resilient cushion and an inflatable bladder are positioned. The case includes an outer panel which is pivotally secured to the upper panel of the case and movable between first and second positions of abduction. The inflation and deflation of a pneumatic bladder cause the outer panel to be moved continuously. The removable support member has an interior compartment which houses a resilient cushion. The exterior surface of the outer panel allows for a sling, making this shoulder and arm support customizable to the patient, position of comfort, and the phase of the rehabilitation process.
