Conclusions: Patients who received movement-activated electrical muscle stimulation (Shoulder Pacemaker) demonstrated significant improvements in shoulder function, mobility, and patient satisfaction scores (SSV) compared to the control group. This type of therapy can enhance clinical outcomes in patients after reverse shoulder arthroplasty (RSA) even more than a year post-surgery.
Do Patients Benefit From Self-Based Training With Or Without Electromyostimulation 1 Year After Implantation After Reverse Shoulder Arthroplasty? A Prospective-Randomized-Controlled-Study
Aim:
To compare the clinical results of patients who underwent Reverse Shoulder Arthroplasty (RSA) and participated in a guided home-based training protocol (Control Group) against patients who underwent the same training protocol with an additional dynamic electromyostimulation (Shoulder-Pacemaker™, Intervention Group).
Background: It has been reported that the clinical results of patients who underwent RSA reach a plateau one year after surgery. Electromyostimulation (EMS) has shown promising results for functional posterior instability; however, its potential benefit has not yet been investigated in patients after RSA. A training protocol was developed by physiotherapists and surgeons for patients who underwent RSA. This study examines whether this training with or without EMS significantly improves shoulder function even one year after RSA.
Methods: This study involved n=34 patients with primary osteoarthritis or cuff tear arthropathy who underwent RSA, with a follow-up of 12-24 months post-surgery. The same implant system was used in all patients. The intervention group (n=17) performed a six-week standardized training program with simultaneous EMS using the Shoulder Pacemaker™, while the control group (n=17) underwent the training program without EMS. Outcome measures included the Constant-Murley Shoulder Score (CS), range of motion (ROM), and Subjective Shoulder Value (SSV), assessed pre- and post-intervention using an automated computer-based method (Show Motion) and additional clinical evaluation. Descriptive statistics and a two-sample t-test (p=0.05) were utilized for statistical analysis.
