Our lab focuses on elucidating the neuro-mechanical basis underlying impaired lower limb function and sensorimotor recovery in persons with neurological injury. Given the nervous system’s tremendous ability to re-organize, we seek to identify innovative paradigms that shape this neural plasticity towards gains in motor performance. We conduct parallel investigations in healthy individuals to further clarify mechanisms of motor control and adaptation. The work from our lab will strengthen the neurorehabilitation communities understanding of how novel strategies can induce plasticity, shape functional recovery, and ultimately enhance mobility and quality of life in persons with paralysis.
In order to study how changes in downstream biomechanics may reflect adaptive neuro-plastic changes, we take an interdisciplinary approach that combines clinical neurophysiology techniques and engineering approaches. Specifically, we leverage neuromodulatory probes (e.g. transcranial magnetic stimulation (TMS), peripheral nerve stimulation), electrophysiological recording/signal processing (e.g. electromyography, electroencephalography), and engineering tools (e.g. robotics, biofeedback) to characterize and address neuromotor impairments.
