This pilot study explored the feasibility and effectiveness of vibration therapy (VT) on muscle and bone health, motor performance, and respiratory function in patients with congenital myopathy (CM). Eleven participants with CM (11.5 ± 2.8 years) underwent 12 weeks of side-alternating VT at 20 Hz for nine minutes per session, four days a week. VT was preceded by a 12-week control period. Assessments included dual-energy X-ray absorptiometry scans, 6-minute walk and 10-meter run tests, muscle function and motor performance assessment, dynamometry, and pulmonary function. VT was well-tolerated, with occasional mild itchiness reported. The median compliance level with VT treatment was 75%. 12 weeks of VT improved the total score of motor function performance by 2.4 units (p=0.006) and velocity rise maximum of the chair rising test by 0.11 m/s (p=0.029). VT was shown to be feasible, safe, and associated with improving motor function performance. Our findings support further exploration of VT's potential health benefits to patients with CM in larger studies involving a longer intervention period. |
