Using EMG biofeedback and electrical stimulation to improve shoulder function after surgery
Electromyography Biofeedback and Neuromuscular Electrical Stimulation of Deltoid in Patients With Reverse Total Shoulder Arthroplasty
NA · National Taiwan University Hospital · NCT06873022
This study is testing if a combination of electrical stimulation and muscle feedback can help people recover better and move their shoulders more easily after shoulder surgery.

What this trial studies
This study investigates the effects of neuromuscular electrical stimulation (NMES) and surface electromyography (sEMG) biofeedback on the deltoid and associated scapular muscles in patients who have undergone reverse total shoulder arthroplasty (rTSA). The research aims to enhance scapular kinematics and muscle activation to prevent complications such as scapula notching. Participants will receive interventions designed to improve deltoid function and overall shoulder movement. The study will assess immediate effects on muscle activation and scapular movement patterns in individuals post-rTSA.
Who should consider this trial
Good fit: Ideal candidates are individuals aged 20 to 85 who are at least three months post-primary reverse shoulder arthroplasty and can achieve shoulder abduction above 90 degrees.
Not a fit: Patients with a history of other shoulder surgeries, neuromuscular diseases, or cognitive disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly improve shoulder function and reduce complications for patients recovering from reverse shoulder replacement.
How similar studies have performed: While the specific combination of NMES and sEMG biofeedback in this context is novel, similar approaches have shown promise in enhancing muscle function in other rehabilitation settings.
