Effects of an Ankle-Foot Orthosis on Gait While Performing an Attention Demanding Task
We hypothesize that: (1) gait stability will be increased when wearing an ankle-foot orthosis (plastic brace supporting the foot and ankle); (2) an attention demanding task will decrease gait stability and (3) the improvement in gait stability due to ankle-foot orthosis use will be greater during an attention demanding task.

- Velocity [ Time Frame: up to one week ] [ Designated as safety issue: No ]walking velocity
- trunk acceleration [ Time Frame: up to one week ] [ Designated as safety issue: No ]trunk acceleration during walking
- Step length variability [ Time Frame: up to one week ] [ Designated as safety issue: No ]variability of right and left step length during walking

People who have had a stroke and have an ankle-foot orthosis.
A quasi-experimental, randomized 2 x 2 factorial within subjects study with the factor of walking condition (2 levels, walking with and without ankle-foot orthotic device) and attention condition (2 levels, walking with and without attention task).
