Sensory Augmentation Methods in Stroke

Participants will complete 8 training sessions over 4 weeks, in which they walk on a treadmill at their self-selected speed. During training sessions, the magnitude of the vibration delivered over the hip abductor musculature will scale with the mechanical state of the pelvis at the start of each step. For example, if the step begins with the pelvis far mediolaterally from the stance foot, the swing leg hip abductors will receive strong vibration. If instead the step begins with the pelvis close mediolaterally to the stance foot, the stance hip abductors will receive strong vibration.

Participants will complete 8 training sessions over 4 weeks, in which they walk on a treadmill at their self-selected speed. During training sessions, the magnitude of the vibration applied to the hip abductors will vary randomly (following a normal distribution) on a step-by-step basis.
