Ankle Foot Orthosis (AFO), Dual Task Walking
Conditions
Keywords
stroke, dual task walking, AFO, FNIRs
Brief summary
The goal of this clinical trial is to learn the effect of carbon fiber ankle foot rothosis (AFO) on dual-task walking perfromance and cognitive load for stroke patients. The main questions it aims to answer are: Does wearing carbon fiber AFO can improve gait and secondary task during dual task walking for individual with stroke ? Does wearing carbon fiber AFO can reduce the prefrontal load during dual task walking for individuals with stroke? Researchers will compare gait, concurrent task performance, and FNIRs activation over prefrontal area under different test conditions (with/without AFO, single walk, cognitive dual walk, motor dual walk) Participants will: execute all different conditions repeatedly in a randomized order. require to visit the lab once, about 2 hours period to complete the whole experimental protocol.
Interventions
DEVICEWear an off the shelf carbon fiber ankle foot orthosis(AFO).
Participants wore an appropriately sized off-the-shelf carbon fiber ankle-foot orthosis (AFO) during the AFO-on condition, compared with not wearing an AFO during the AFO-off condition.
PROCEDUREPerfrom single and dual task walking.
Single-task walking was defined as walking along a 13-m pathway at a self-selected comfortable speed. Dual-task walking was defined as walking along the same pathway while concurrently performing an auditory Stroop test or holding a tray with three wooden blocks stacked on top of each other.
