The purpose of this study is to explore the efficacy of the SaeboVR rehabilitation system for improving functional outcomes related to upper extremity motor recovery in stroke survivors.

The specific objectives are:

1. To explore the participants' level of performance and satisfaction with their performance in self-identified problem areas of daily functioning following a 4-week intervention using the SaeboVR rehabilitation system.
2. To evaluate the efficacy of an intervention protocol that emphasizes task-specific and goal-oriented virtual practice, reflecting the participants' self-identified goal priorities.

This study will employ a multiple single-subject pre-post experimental design, with multiple pre and post measures, to evaluate the potential efficacy of a virtual reality-based treatment using the SaeboVR rehabilitation system in stroke survivors. Comprehensive measurement during the baseline and post-treatment phases will be completed, with each individual to serve as their own control. Participants will make 3 separate visits to the laboratory (approximately 2 days apart) on the Bannatyne Campus at the University of Manitoba prior to the 4 week intervention and again after the intervention. The Arm Activity Measure (ArmA) and the Fugl-Meyer Assessment of Upper Extremity (FMA-UE) will be used both pre and post intervention as well as the Canadian Occupational Performance Measure (COPM) to measure participants' performance on self-identified occupational performance issues and their level of satisfaction with their performance. Two participants will be recruited upon discharge from inpatient stroke rehabilitation at the Riverview Health Centre, Winnipeg, Manitoba, and upon entry into this study, will receive one-to-one treatment and supervision using the SaeboVR rehabilitation system for approximately 1 hour per session, 2 to 3 times per week for 4-weeks.

• have no noted visual neglect

Exclusion Criteria:
