Neuromechanical mechanisms for locomotor learning in humans with and without neurological disorders.
My group investigates the human ability to adapt walking patterns and learn new movements through interactions with the world. To this end we combine psychophysical experiments and computational tools to investigate locomotor learning in unimpaired subjects and patients with cortical lesions. Current studies specifically study 1) the adaptability of muscle coordination in patients and healthy subjects when they experience novel walking conditions, 2) the prediction error driving locomotor learning to sustained environmental perturbations, and 3) the generalization of adaptation effects from treadmill walking to over ground locomotor movements and 4) cognitive factors mediating locomotor learning and its generalization
