Using computational modeling to investigate motor control gait impairments after stroke

Objective

The goal of this study is to determine whether associations between knee motor control impairments and abnormal hip and pelvic neuromechanical patterns be found using a neuromechanical bipedal model.

How to Participate

• Suffered a first ever monohemispheric stroke
• Chronic: stroke onset > 6 months
• MCA infarcts (it will be noted if they have a cortical component)
• Unilateral brain lesion confirmed by an imaging study (e.g. CT, PET, or MRI)
• Ability to stand without assistance.
• Clinically observable gait asymmetry (i.e. exhibit a decrease in peak knee flexion in the paretic limb of more than two standard deviations from normal)
• Ambulatory at the time of enrolment with a maximum gait velocity of 0.6m/s, or half normal walking speed.
