Stopped: The study was stopped during the COVID-19 Pandemic in March 2020 to prevent transmission. It did not reopen due to aging of the virtual reality technology.
People with one arm that does not function well due to a stroke, head injury, or cerebral palsy, and a fully functional other arm, will be randomly assigned to receive one of the two interventions first, followed by the other intervention. The two interventions include a task-based intervention and a virtual reality intervention that provides a reflected image of the involved arm. The task-based intervention will consist of setting up activities of interest to be done using the involved arm and structuring practice and meaningful feedback to assist learning. The virtual reality intervention will consist of the person wearing the virtual reality device and practicing virtual tasks using the intact arm while seeing the involved arm. Intervention sessions will last approximately 30 minutes and will be held 3 times/week for 3 weeks each for a total of 9 sessions for each intervention. Testing of the involved arm's function will be done before the interventions, after receiving 9 sessions of each intervention, and one month after completing the second intervention received.
