Interdisciplinary Human Movement Science Lab
Focus: 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.
