The Cognitive-Motor Behavior Lab integrates cognitive neuroscience and motor control to examine interactions between attention, cognition and language, and mobility to optimize neurorehabilitation outcomes in people with neurological disorders.

Current Research

  • The study is examining aspects of mobility (walking, balance, fear of falling) and cognitive-communication (language, attention, memory) at the time of discharge from inpatient rehabilitation to home that are associated with falls and community reintegration in the first 3 months after discharge
  • Funded by the Tedy’s Team Center of Excellence in Stroke Recovery
  • This clinical trial is investigating if combining a medication for walking impairment (dalfampridine, Ampyra®) with physical therapy can enhance recovery of walking ability and sustain the benefits of therapy longer than either treatment provide on its own.
  • Funded by the National Multiple Sclerosis Society
  • registration: NCT06136728
  • The goal of this real-world clinical study is to evaluate adherence to PoNS therapy (device + physical therapy) and understand the relationship between adherence to PoNS therapy regimen and therapeutic functional outcome.
  • Funded by Helius Medical Technologies, Inc.
  • The goals of this study are to determine what visual information is sampled during walking with and without distraction and to examine the association between eye movement and postural stability during standing and walking.
  • This study is currently enrolling individuals with and without balance difficulty who have experienced a stroke or who have multiple sclerosis.
