Development of Walk Assist Device to Improve Community Ambulation

Completed · Not applicable

Conditions studied: Stroke

In brief

Hypothesis/Specific Aims: The purpose of this study is to determine the effect of training with the Stride Management Assist (SMA) device vs. Impairment based physical therapy (IPT) on descending corticospinal drive to the lower limb muscles in patients post stroke. The investigators hypothesize that long-term SMA use would strengthen the connections between the motor areas of the brain and the lower limbs. Specifically, individuals in the SMA group will show higher corticospinal excitability of the lower limb muscles compared to those in the IPT group.
