Effect of Pulse Electromagnetic Stimulation on Pain and Functional Mobility in Patients with Frozen Shoulder: A Randomized Controlled Trial

The objective of this randomized controlled trial is to evaluate the therapeutic efficacy of Pulsed Electromagnetic Stimulation (PEMS) as an adjunct to conventional physiotherapy for managing frozen shoulder (adhesive capsulitis). A total of 30 participants will be recruited via convenient sampling and randomly assigned to one of two arms. Group A (Experimental) will receive PEMS in addition to a conventional physiotherapy regimen consisting of range of motion exercises, stretching, and manual therapy. Group B (Control) will receive the conventional physiotherapy regimen alone. The intervention will be administered 3 times per week for a duration of 4 weeks (total 12 sessions). Primary outcomes include pain intensity measured by the Numerical Pain Rating Scale (NPRS), while secondary outcomes include shoulder range of motion via goniometry and functional disability measured by the Shoulder Pain and Disability Index (SPADI). Assessments will be conducted at baseline, weekly, and post-intervention to determine significant differences between the two treatment protocols.
