Objective: To evaluate the rehabilitative impact of targeted mechanoacoustic vibration therapy on mobility, bone mineral density (BMD), pain, and sleep quality in elderly women with moderate-to-severe idiopathic Restless Legs Syndrome (RLS).

Background: Postmenopausal osteoporosis and age-related functional decline are significantly exacerbated by the chronic sleep deprivation and motor restlessness inherent to RLS. While pharmacological interventions remain the standard of care, adjunctive physical therapies are critically needed to address secondary musculoskeletal deterioration. This study investigates whether high-frequency mechanoacoustic vibration can safely mitigate these compounded risks in a vulnerable neurological cohort.

Method: A 6-month prospective, controlled intervention trial enrolled 82 elderly women (aged 65–75 years) diagnosed with idiopathic RLS. Participants were assigned to an intervention group (n = 42; receiving 300 Hz mechanoacoustic vibration therapy, 30 min/session, 3 days/week alongside standard care) or a control group (n = 40; standard pharmacological therapy alone). Clinical assessments included the International RLS Rating Scale (IRLS), Berg Balance Scale, Tinetti Scale, DXA for lumbar and femoral BMD, isokinetic dynamometry, and the Pittsburgh Sleep Quality Index (PSQI).

Results: Mechanoacoustic vibration therapy yielded profound multidimensional improvements compared to controls. The intervention cohort demonstrated significant gains in lumbar and femoral neck BMD T-scores, isokinetic muscle strength, and Tinetti gait stability (p < 0.01). Pain scores and IRLS severity were substantially reduced, correlating with enhanced Berg balance scores (p < 0.001). PSQI metrics indicated significantly increased sleep duration (p = 0.001) and overall sleep quality (p = 0.05). Notably, reliance on pharmacological rescue medications trended downward in the intervention group, though this reduction did not reach statistical significance (p = 0.12).

Conclusion: Adjunctive mechanoacoustic vibration therapy offers a robust, non-invasive rehabilitation pathway for elderly women with RLS. By simultaneously addressing sensorimotor symptoms, bone health, and sleep architecture, this multimodal intervention significantly enhances functional independence and provides a critical buffer against osteoporotic progression.
