Research topics: Gait, postural control, falls and movement disorders in health (e.g., normal, aging, maturation) and pathology (e.g., Parkinson’s disease, post-stroke, Alzheimer’s disease). Areas of focus include studies of the stride-to-stride fluctuations of gait and the factors that contribute to and regulate these changes and cognitive function-gait interactions. We investigate balance and gait on three closely inter-related planes: a) study of underlying physiology and patho-physiology; b) development of new “bio-markers” that can be used for early diagnosis, prognosis, and for quantitative tracking of disease progression, aging, and the response to therapeutic interventions (e.g., at-home monitoring) and c) development and assessment of novel interventions for enhancing balance and gait (e.g., using virtual reality, pharmacologic therapy, motor learning).
Projects in the lab:
- fMRI, EEG, and fNIRS imaging of balance and gait in Parkinson’s disease and aging
- Virtual-reality based intervention for gait and cognitive function.
- Freezing of gait: motor and non-motor mechanisms.
- Bilateral coordination of gait
- What cognitive abilities contribute to gait and fall risk?
- Long-term monitoring of gait and mobility at home
- Anxiety, stress, fear and their relationship to movement disorders
- Cognitive interventions for improving gait
- Genetic contributions to gait and mobility
- Non-invasive brain stimulation for gait and cognition
