Brief Summary:
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.
Detailed Description:
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 iterations and improved implant positioning, these continue to be a source of frustration with patients and surgeons alike.
Poor scapulothoracic motion is associated with poor shoulder range of motion, especially after RSA. Past investigators have shown that in certain RSA patients, there is a near complete loss of glenohumeral motion and forward elevation and abduction is highly dependent on scapulothoracic motion. In a separate study, In addition, these investigators demonstrated that internal rotation after RSA is largely dependent on scapulothoracic motion. Several years ago, a device called the Shoulder Pacemaker (Alyve Medical, Denver, CO) was developed initially for the treatment of functional instability in the setting of scapular dyskinesis. It functions as a wearable muscle electrostimulator that allows for periscapular muscle stimulation as well as feedback on shoulder range of motion. The motion technology recognizes muscle movement and automatically sets the appropriate stimulation intensity according to the movement. This improves scapular muscle recruitment during range of motion. While the data is limited, there has been some early promising results for this pathology. As function after RSA is particularly reliant on scapulothoracic function, the current investigators may infer that use of the Shoulder Pacemaker device may function well in patients with reverse shoulder replacements. Specifically, the device would allow patients to train their periscapular musculature after RSA to improve global shoulder motion and function. To the current investigators knowledge, there is no current research on the use of the Shoulder Pacemaker after RSA.
