Summary

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.

Conditions

  • Subacute Stroke

Interventions

BEHAVIORAL

Blood Flow Restriction + Dual Task Training

Participants will undergo lower limb resistance and gait training while wearing blood flow restriction cuffs at 40% of their individualized arterial occlusion pressure. Tasks include walking, sit-to-stand, and obstacle crossing combined with verbal fluency or serial subtraction. Training is performed 3 times per week for 5 weeks.

BEHAVIORAL

Dual Task Training Only

Participants will perform the same cognitive-motor dual task training without blood flow restriction. Tasks include forward walking, obstacle crossing, and sit-to-stand exercises with concurrent cognitive tasks such as verbal fluency or serial subtraction. Training is performed 3 times per week for 5 weeks.
