Stroke recovery and rehabilitation

Neurofeedback for stroke rehabilitation

Patterns of brain activity change after stroke. Neurofeedback aims to address impairment in brain activation through brain activation training. Neurofeedback involves displaying patterns of brain activity to a stroke survivor, in real time, while a task is being performed with the affected hand. By promoting beneficial brain activity patterns, this approach aims to extend or enhance the benefits of therapy.

learning and sleep after brain injury

Motor learning is central to rehabilitation after brain injury. Sleep is important for consolidation of learning, but brain injury may affect sleep continuity. People who have had a stroke or brain injury commonly complain of tiredness, daytime sleepiness and increased need for sleep. We are aiming to assess the role of sleep quality on motor recovery in people receiving inpatient rehabilitation for stroke or brain injury and people in the community.
