Research Interests
The primary goals of our lab are to study ways to enhance walking ability in patients with neurological injuries, particularly those with incomplete spinal cord injury and stroke. We continue to investigate the efficacy of robotic- and other non-motorized devices on improving locomotor capacity in these patient populations using clinical, biomechanical, and physiological measures. Another primary interest is the influence of various neuroactive, pharmacological substances on strength, spasticity/spasms, and walking ability in these individuals, particularly when combined with physical intervention strategies.
