Brief summary
This study investigated the effect of treadmill walking training with and without random speed changes in persons in the chronic stage of stroke. It was hypothesized that random speed change group will show less attention and balance demands for speed change in level walking.
Detailed description
This study includes chronic stroke patients who will be randomly assigned to blocked or random walking speed change group to receive 30 min per session, 3 sessions per week for 2 weeks' walking training on a treadmill. The outcome measures include gait characteristics under 3 tasks x 3 speed conditions x 2 attention conditions on an obstacle-free walk way. The three tasks are normal walking, narrow based walking and obstacle crossing. The three speed conditions are constant (preferred) speed, speeding up (preferred to maximum speed), and slowing down (maximum to preferred speed). The two attention conditions are none and serial subtraction of 3 during walking. Clinical sensorimotor function assessment, including hand grip strength, plantar sensitivity, stroke rehabilitation assessment of movement and Fugl-Meyer lower extremity motor scale will be conducted for subject characterization.
Interventions
OTHERTreadmill walking training with random speed changes
Participants were asked to walk in different gait speed randomly on the treadmill (80%, 90%, 100%, 110% and 120% of preferred speed). The training speed would be changed in every 15 seconds in 2-minutes-section. 2 minutes/ section, 10 sections/ day, 3 days/ week, 2 weeks. 1 minute rest time would be held between sections.
OTHERTreadmill walking training with blocked speed changes
Participants were asked to walk in same gait speed on the treadmill per day (80%, 90%, 100%, 110% and 120% of preferred speed, respectively). 2 minutes/ section, 10 sections/ day, 3 days/ week, 2 weeks. 1 minute rest time would be held between sections.
