Riassunto dello studio

Fifty patients with subacromial impingement syndrome were randomized to either neuromuscular electrical stimulation with exercise training (n=25) or exercise training alone (n=25). The primary outcome of interest was the Disabilities of the Arm, Shoulder, and Hand (DASH) score at 8 weeks. Secondary outcomes of interest included pain at rest, during movement, and at night, measured using the Visual Analog Scale (VAS), range of motion, and maximum isometric strength in flexion, abduction, external rotation, and internal rotation at weeks. Pain with movement and at night were significantly lower in the exercise therapy with neuromuscular electrical stimulation group at 8 weeks. With regard to range of motion, external rotation was better in the exercise therapy group and all assessments were significantly better in the intervention group for muscle strength. All other outcomes were similar between the two groups.
