Study of Blood Flow Restriction and Cognitive-Motor Dual Task Training to Improve Strength, Gait, and Balance in People With Subacute Stroke

This study aims to evaluate the effects of individualized blood flow restriction (BFR) training combined with cognitive-motor dual task intervention on lower limb muscle strength, gait ability, and fall stability in patients with subacute stroke. A total of 28 participants will be randomly assigned to either the experimental group (BFR + dual task training) or the control group (dual task only). The intervention will last for 5 weeks, with training sessions conducted three times per week, each lasting 40 minutes. The primary outcome is lower limb strength measured by the Five Times Sit-to-Stand Test. Secondary outcomes include gait ability (10-Meter Walk Test and Functional Gait Assessment) and fall stability (Timed Up and Go Test and Korean version of the Falls Efficacy Scale-International). This study seeks to verify whether combining low-pressure BFR training (40% of arterial occlusion pressure) with dual task training can be a clinically effective strategy for improving motor and cognitive function in individuals with subacute stroke.
