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.
||Observational Model: Case-Crossover
Time Perspective: Cross-Sectional
||Effects of an Ankle-Foot Orthosis on Gait While Performing an Attention Demanding Task in People With Poststroke Hemiplegia
Primary Outcome Measures:
- Velocity [ Time Frame: up to one week ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- 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
- The Berg Balance Scale [ Time Frame: up to one week ] [ Designated as safety issue: No ]
Functional balance measured using the Berg Balance Scale short form.

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).
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
People who have had a hemiplegic stroke and have an ankle-foot orthosis.
- be over the age of 18;
- have the presence of hemiplegia after stroke;
- be wearing an ankle-foot orthosis for at least 6 weeks;
- be able to walk independently and comfortably for a minimum distance of 12 m with or without assistive aids (AFOs, canes and walkers);
- be able to read and understand English, follow verbal instructions and provide verbal answers to questions;
- be able to reach criterion on the attention task (described below)
- be competent to give informed consent as determined by clinical team and noted in the health chart
- have history of balance deficits not related to stroke;
- be at high risk of falling during the study;
- suffer from severe aphasia or dementia as determined by health chart and/or initial cognitive screening using the Montreal Cognitive Assessment (MoCA) test.
