The apparatus to assist sternal rehabilitation includes a torso belt circumscribing an abdomen of a patient, a first humeral restraint coupled to the torso belt, and a second humeral restraint coupled to the torso belt. Each humeral restraint circumscribes an upper arm of the patient between a glenohumeral joint and an antecubital space of the upper arm. The humeral restraints substantially confine the upper arms to a position lateral, slightly anterior, and to the side of a torso of the patient. The torso belt may include a substantially inelastic flexible material. The torso belt may also include a comfort material coupled to the substantially inelastic flexible material. The comfort material may be interposed between the substantially inelastic flexible material and the torso. The torso belt may circumscribe the abdomen below a pectoral line and above a pelvic line of the patient.
