Virtual reality feedback to boost push-off from the weaker leg during robot-assisted walking after stroke

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The team uses a VR-integrated visual feedback system embedded in the Morning Walk® end-effector robot to encourage more symmetrical use of the paretic and non-paretic limbs during robot-assisted walking. A total of 30 adults (15 post-stroke, 15 healthy controls) will complete a single-session gait training while investigators record spatiotemporal gait parameters, muscle activity, foot pressure, and vertical ground reaction forces. Stroke participants must be at least one month post-stroke and able to walk 10 meters with or without assistive devices, and the protocol includes safety measures such as a saddle-type weight support and real-time heart monitoring. Outcomes in the post-stroke group will be compared with healthy controls to see if real-time VR propulsion feedback improves paretic limb propulsion and gait symmetry.
