Biofeedback to Increase Propulsion During Walking After Stroke

Approximately 15,000 Veterans are hospitalized for stroke each year with new cases costing an estimated $111 million for acute inpatient, $75 million for post-acute inpatient, and $88 million for follow-up care over 6 months post-stroke. Rehabilitation of walking ability contributes to these costs. To "walk again" is the number one stated goal for Veterans who have had a stroke. Teaching patients post-stroke to use their weak leg while they are regaining walking function and to not compensate by over-using their strong leg is necessary to restore safe, efficient walking ability. This project will determine if providing biofeedback (an audible tone) from pressure-sensitive shoe insole sensors, that encourage use of the weaker leg during walking training, in addition to therapists' feedback, will help Veterans regain use of their weak leg, improve their endurance and improve their balance when walking in challenging environments.
