Background: Contractures are a common issue in geriatric patients, particularly in nursing facilities, where prolonged immobility can reduce joint mobility and function. These conditions, characterized by tightness in muscles, tendons, or skin, impact quality of life and complicate caregiving. Repetitive Peripheral Magnetic Stimulation (RPMS) therapy is a promising non-invasive treatment for healing, reducing inflammation, and improving joint function, potentially aiding elderly patients in skilled nursing facilities.

Methods: This study employed an ABA design (baseline-treatment-baseline) to assess the effects of combined RPMS and Passive Range of Motion (PROM) therapy on knee contractures in elderly patients. Twelve participants (mean age 83.3 ± 5.2 years; 4 males, 8 females) were recruited into a study protocol consisting of 3 phases: Phase A1 (RPMS+PROM), Phase B (PROM), and Phase A2 (RPMS+PROM). The primary goal was to assess knee range of motion (ROM) improvements, with mobility changes as a secondary focus. ROM data were collected at baseline and after each phase using a goniometer.

Results: No participant experienced a decline in knee ROM after completing the treatment program, although some showed slight fluctuations during individual phases. The average improvement across both limbs was 20°, with statistically significant changes observed in the dominant limb after Phase B and in both limbs following Phase A2, compared to baseline.

Conclusions: RPMS therapy combined with PROM exercises showed promise for improving knee ROM. However, variability in outcomes highlights the need for personalized treatment plans. Future research should explore factors that contribute to sustained improvements and refine protocols for long-term benefits.
