This Study is About the Efficacy of Repetitive Peripheral Magnetic Stimulation on the Treatment of Shoulder Subluxation in Subacute Stroke Patients.

The goal of this clinical trial is to study the efficacy of repetitive peripheral magnetic stimulation (rPMS) on shoulder subluxation in subacute stroke patients. The main questions it aims to answer are Could rPMS reduce shoulder subluxation and improve upper-limb motor recovery in subacute stroke patients? Researchers will compare real rPMS to sham rPMS to see if rPMS works to improve shoulder subluxation and upper-limb motor recovery in subacute stroke patients. Participants will: * Get real rPMS or sham rPMS for 20 minutes, 5 days a week for 2 weeks * Get conventional rehabilitation program 5 days a week for 2 weeks * Follow-up at 2-, 4-, 8- and 12-weeks after first day of treatment
