The investigators purpose of the proposed study is to use the FDA approved Shoulder Pacemaker device in patients undergoing reverse shoulder arthroplasty and study the functional outcomes compared to a standard post-operative rehabilitation program. The investigators hypothesize that use of the Shoulder Pacemaker reduce pain and will allow for improved range of motion and function in patients undergoing RSA. The findings of this research may very well improve function in RSA patients through a novel, non-invasive approach.
The reverse shoulder arthroplasty (RSA) has increased utility in recent years for shoulder conditions such as rotator cuff tear arthropathy, massive irreparable rotator cuff tears, severe glenohumeral arthritis, proximal humerus fracture, and failed shoulder arthroplasty. While RSA may commonly be the only surgical treatment for some of these conditions, the outcomes and adverse event profiles are significant. Specifically, RSA patients often complain of poor range of motion and function with the arm above the head. Despite many attempts at solving these shortcomings with new implant design it…
