Interdisciplinary Human Movement Science Lab


The goal of the Interdisciplinary Human Movement Science Lab is to understand the neurophysiological and biomechanical causes of altered muscle function and movement patterns for individuals who have had a stroke. In order to meet our ultimate goal of improving functional mobility (primarily walking) in people who have had a stroke, we are developing and assessing the effects of novel walking rehabilitation strategies. Supported, in part, by the North Carolina Biotechnology Center, the lab is fully equipped with an 8 camera Vicon MX40+ motion capture system, Bertec dual-belt instrumented treadmill, Motion Lab Systems 16-channel EMG system, GaitRite mat, Cybex Norm, custom-designed projection and head-mount immersive virtual environment and dynamic body weight support system. We are therefore capable of assessing human movement to improve rehabilitation strategies for individuals with a wide variety of pathologies.

Current Projects:

The Use of Visual and Proprioceptive Feedback for Restoring Locomotor Symmetry and Forward Propulsion Post-Stroke

The overall goal of this project is to explore the role of visual and proprioceptive feedback during treadmill training for individuals following stroke.

Funding: American Heart Association (PI: Lewek) and NIH P41EB002025 (PI: Superfine; core PIs: Brooks/Whitton)
