Study Summary

Older adults and stroke survivors often have difficulty performing complex walking tasks, due in part to changes in the brain. One task often overlooked is turning, which can lead to injury when performed poorly. The investigators will use non-invasive brain stimulation to assess brain activity and relate those observations to turning performance in older adults and stroke survivors.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
