Brief summary
Virtual Occupational Therapy Application (VOTA) combines low-cost human motion tracking, commercial game engine technology, and evidence-based Occupational Therapy (OT) practice in a computer-based virtual world in which stroke patients practice activities of daily living (ADLs). The protocol investigates the efficacy of VOTA therapy for Upper Extremity (UE) motor recovery and assesses system usability and user acceptance.
Interventions
BEHAVIORALVOTA Therapy
During sessions of approximately one hour in duration, participants practice performing virtual activities of daily living (ADLs) using the VOTA system. During this practice, the participant's real-world motion is replicated by an avatar's motion in the virtual world. To complete the activities, participant's must perform a wide range of functional arm movements while interacting with virtual objects. Individuals are asked to perform three such one-hour virtual ADL practice sessions per week over a participation period of approximately eight weeks.

Inclusion criteria
* Participant is a hemiparetic stroke survivor; * Time since last stroke at least 3 months; * Participant has antigravity strength at the elbow to at least 45 degrees of active flexion in the stroke affected arm; * Participant has antigravity shoulder strength to at least 30 degrees each in active flexion, abduction/adduction, and 15 degrees in active rotation from an upright seated position in the stroke affected arm; * Participant has visual acuity with corrective lenses of 20/50 or better;
Exclusion criteria
* Existing participation in an upper extremity stroke rehabilitation program or planned participation during the study period; * Inability to understand and follow verbal directions; * Determination that participation would result in over exertion or significant discomfort or pain; * Determination that participation would result in significant agitation or elevated stress; * Withholding or withdrawal of consent by the participant; * Visual field deficit in either eye that impairs the ability to view the computer monitor; * Hemispatial neglect that impairs the ability process and perceive visual stimuli provided through the computer monitor;
