The effects of impaired post-stroke coordination and motor pathway integrity on mobility performance

Funding Agency: The Veterans Affairs (VA)
Project Description: The overall goal of this project is to beter understand the contribution of corticospinal and corticoreticular pathways to: the control of non-steady state walking mobility tasks, the observed deficits in module coordination resulting from their injury, and recovery of walking function. This project will also seek to understand how impaired muscle coordination limits biomechanical function execution and restricts mobility performance in a variety of tasks deemed fundamental to household and community walking.
Collaborators: Dr. Steve Kautz at the Medical University of South Carolina.

Influence of lateral stabilization on walking ability post-stroke

Funding Agency: National Institutes of Health (NICHD)

Project Description: The overall goal of this project is to better understand how mediolateral balance control mechanisms are impaired and compensated for post-stroke to motivate more targeted interventions that improve balance control.
Collaborators: Dr. Jesse Dean and Dr. Christain Finetto at the Medical University of South Carolina.

Wheelchair propulsion optimization

Project Description: The goal of this project is to using computer modeling and simulation techniques to identify the optimal manual wheelchair propulsion technique to reduce upper-extremity demand placed on the wheelchair user.
Collaborators: Dr. Phil Requejo and Dr. Sara Mulroy at Rancho Los Amigos National Rehabilitation Center.

Effect of prosthetic foot-ankle stiffness on amputee function

Funding Agency:The Veterans Affairs (VA)
Project Description: The overall goal of this project is to identify causal relationships between prosthetic foot-ankle stiffness and amputee gait mechanics and develop a predictive prescription tool to improve rehabilitation outcomes. This project uses additive manufacturing techniques (SLS) to fabricate patient-specific prosthetic feet with a wide range of mechanical properties.
Collaborators: Dr. Glenn Klute at the VA RR&D Center for Limb Loss Prevention & Prosthetic Engineering.


Mechanically-induced stochastic resonance to improve amputee gait

Funding Agency: The Veterans Affairs (VA)
Project Description:The purpose of this research is to determine if mechanically-induced stochastic resonance, applied to the residual limb of a diabetic lower limb amputee or the plantar surface of their intact foot, can enhance peripheral sensation sufficiently to result in improved postural stability and gait.
Collaborators: Dr. Glenn Klute at the VA RR&D Center for Limb Loss Prevention & Prosthetic Engineering; Gordon Bosker, Gail Walden and Jim Schroeder at the Andrew J. Gitter Research Center South Texas VA Medical Center.

The influence of ankle-foot orthoses on post-stroke hemiparetic walking

Funding Agency: The American Heart Association (AHA)

Project Description: The goal of this project is to investigate the influence of ankle-foot othoses (AFOs) on gait performance in healthy and post-stroke hemiparetic subjects over a range of walking conditions.
Collaborators: Dr. Arian Vistamehr at Brooks Rehabilitation Hospital and Dr. Steve Kautz at the Medical University of South Carolina.
