Cortical Processes During Walking Post-stroke

The study aims to use novel mobile imaging techniques with high-density electroencephalography (EEG) to quantify cortical processes synchronized to the biomechanics of walking. Here, the study has two aims - the primary aim is to quantify the cortical processes that contribute to gait dysfunction early post-stroke, and the second aim is to determine how cortical processes are mediated by mechanical assistance during early gait training post-stroke.Participants will wear an electroencephalography (EEG) cap to measure brain activity and other non-invasive physiological sensors. Participants will be asked to perform different tasks, such as walking at different speeds and walking with different levels of body weight support.

Inclusion Criteria for post-stroke patients:Participants will have a unilateral brain lesion within six months prior to participation in this project;Paresis confined to one side;Ability to walk for 10 meters continuously;Absence of severe cognitive dysfunction as demonstrated by a Mini-Mental score greater than 24;Absence of severe concurrent medical problems;Ability to provide informed consent.Exclusion Criteria for age-matched adults:Any major neurological, cardiovascular, orthopedic, and psychiatric diagnoses
