A Comparison between Proprioceptive Vibration Training and Conventional Training in Stroke Rehabilitation

Stroke is a leading cause of long-term disability globally, characterized by impairments in motor and sensory functions and limitations in activities of daily living (ADL). Proprioceptive vibration training (PVT) has recently gained attention as a promising rehabilitation approach to activate proprioceptive systems and improve motor function. This study evaluated the effects of proprioceptive vibration training (PVT) on lower limb motor function and activities of daily living (ADL) in chronic stroke patients. This retrospective study involved 28 chronic stroke patients who were divided into a CPT group (n=14) and a PVT group (n=14). Both groups underwent five 30-minute sessions per week for four weeks. The PVT intervention utilized a vibration platform set at 20 Hz, with exercises focusing on lower limb strengthening, weight-bearing on the affected limb, and balance training. Outcomes were assessed using the Fugl-Meyer Assessment for Lower Extremity (FMA-LE) and the Modified Barthel Index (MBI). Statistical analyses were conducted to evaluate pre- and post-intervention differences and intergroup comparisons. PVT significantly improved Fugl-Meyer Assessment-Lower Extremity (FMA-LE) scores (+26.09%) and Modified Barthel Index (MBI) scores (+33.39%) compared to CPT. A moderate positive correlation between lower limb function and ADL (r = 0.60, p < 0.01) was observed. PVT enhances proprioceptive stimulation, increases muscle activation, and reduces spinal excitability, improving neuromuscular control. These results support PVT as an effective and stable neurorehabilitation method, providing superior outcomes in lower limb function and ADL performance compared to conventional physical therapy.
