Official Title: Effects of an Ankle-Foot Orthosis on Gait While Performing an Attention Demanding Task in People With Poststroke Hemiplegia

Brief Summary: 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.

Detailed Summary: 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).

Original Primary Outcome: Velocity [ Time Frame: one day ]

walking velocity


Current Secondary Outcome:

  • trunk acceleration [ Time Frame: up to one week ]
    trunk acceleration during walking
  • Step length variability [ Time Frame: up to one week ]
    variability of right and left step length during walking
  • The Berg Balance Scale [ Time Frame: up to one week ]
    Functional balance measured using the Berg Balance Scale short form.
