Optimizing Gait Symmetry After Stroke Using Mechanical Constraints and Sensory Feedback

Participants will walk on an instrumented treadmill under split-belt and/or tied-belt conditions depending on their walking capacity. The belt speeds will be adjusted to facilitate locomotor adaptation and evaluate propulsion symmetry.

Participants will walk on a treadmill (Split-belt and/or Tied-belt) with backward-directed resistance applied at the pelvis, ankle, or both. The resistance is used to challenge paretic leg propulsion and assess adaptive gait responses.

Real-time feedback-visual, auditory, or combined-will be provided based on the propulsive force generated during split-belt and/or tied-belt treadmill walking, with or without mechanical resistance.
