Virtual reality is a video game in which a person and their real-time movements are represented on a screen in a virtual environment. This study will compare the use of multi-user virtual reality (VR) to single-user VR to determine if either provides superior engagement in upper extremity therapy and greater motivation to perform repetitive training.
Stroke survivors will participate in a longitudinal study in which they will have the opportunity to perform rehabilitative training with multi-user VR and single-user VR modes in their homes. They will use each mode for 2 weeks, completing 4 session per week, each session is 1 hour long. Upper extremity motor control, level of engagement, and active range of motion will be assessed at time points during the intervention period.
Subject evaluations will take place before the intervention, at the midpoint of intervention (between switching from multi-user to single-user modes, or vice versa), and at the end of the intervention.
The investigators hope to address two aims:
Aim 1: To determine if the use in-home multi-user virtual reality treatment results in greater engagement in therapy compared with in-home single user virtual reality treatment.
Aim 2: To determine if in-home virtual reality treatment results in greater practice
The investigators hypothesize that stroke survivors will be more engaged in therapy when training with the multi-user VR system and this will translate into greater practice.

|Type||Measure||Time Frame||Safety Issue|
|Primary||Hand displacement during each session||Distance hand moves on average per session during each 2-week treatment phase (each subject will complete 2, 2-week phases of treatment. One 2-week phase being the Single-user mode and the other 2-week phase being the Multi-user mode)|
|Secondary||Therapy mode amount of use||2 week treatment phase|
|Secondary||Change in Active Range of Motion||First measure taken at baseline, then also at the end of the first 2-week treatment phase and finally at the end of the second 2-week treatment phase.|
|Secondary||Comparison of Intrinsic Motivation Inventory Score between therapy modes||First measure taken at the end of the first 2-week treatment phase; Second measure taken at the end of the second 2-week treatment phase.|
