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.

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).
