Objectives: Shoulder subluxation is a common problem after stroke. It causes shoulder pain that affects activities of daily living. This study aimed to investigate the effect of repetitive peripheral magnetic stimulation on shoulder subluxation after stroke. Methods: We enrolled 12 consecutive patients who, as a result of stroke, suffered shoulder subluxations, measuring at half of a fingerbreadth or more. All subjects underwent conventional rehabilitation, as well as repetitive peripheral magnetic stimulation of their supraspinatus, posterior deltoid, and infraspinatus muscles. We assessed the following parameters: shoulder subluxation, evaluated as the acromio-humeral interval using measurements taken from X-rays; shoulder pain, evaluated using the Numerical Rating Scale; the active range of motion of shoulder abduction; and the motor impairment of the upper extremities, evaluated using the upper extremity of the Fugl-Meyer Assessment scale. Results: The acromio-humeral interval before treatment was 22.8 ± 5.7 mm (mean ± SD). It significantly decreased to 19.6 ± 7.0 mm (p = 0.004) after treatment. Shoulder pain (p = 0.039), active range of motion of shoulder abduction (p = 0.016), and total (p = 0.005), subscale A (p = 0.005), and subscale C (p = 0.008) Fugl-Meyer Assessment scores also improved significantly after treatment. Conclusions: Repetitive peripheral magnetic stimulation effectively reduced shoulder subluxations and shoulder pain caused by stroke and improved voluntary upper-limb movements in stroke patients.
