This study aims to evaluate the efficacy of combined pulsed electromagnetic field (PEMF) treatment and physical therapy on pain, stiffness, functional limitation in patients with knee osteoarthritis (OA). In this double-blind, randomized-controlled study, a total 70 female primary OA (mean age: 59.74±9.82 years; range, 40 80 years) were randomly allocated into PEMF sham groups between March 2014 July 2015. Both received 15 sessions over three weeks. Additionally, group for 30 min/day, while control PEMF. The assessed by Visual Analog Scale (VAS), Western Ontario McMaster Universities Arthritis Index (WOMAC), Physician Global Assessment (PGA) scale before seven weeks after treatment. Regardless group, all patients' pain levels significantly improved both scales at (p<0.001). had less than based VAS score (p=0.003). lower stiffness (p=0.008). Recovery ratios PGA higher (p<0.05). Patients who receive addition have more reduction improvement. Based these findings, is safe well-tolerated choice patient population.
