Riassunto dello studio

Eighty-eight patients undergoing reverse total shoulder arthroplasty were randomized to receive neuromuscular electrical stimulation (NMES; n=44) or no neuromuscular stimulation (non-NMES; n=44). Clinical outcomes such as pain, shoulder function, and range of motion were recorded at 3, 6, and 12 months. Pain scores were measured using the Visual Analogue Scale (VAS), and shoulder function was measured using the following measurement tools: American Shoulder and Elbow Surgeons score (ASES), Constant-Murley score, range of motion (ROM) of forward flexion, abduction, and external rotation. Power measurements and deltoid thickness were also measured. Overall, no significant differences were reported between the NMES and non-NMES groups at all time points with the exception of power scores for external rotation at 6 months, and external rotation ROM scores at 3 and 6 months, with better scores in the NMES group.
