Optimizing a Home-based Virtual Reality Exercise Program for Chronic Stroke Patients: A Telerehabilitation Approach

Stroke is a leading cause of death and long-term disability worldwide and its incidence is on the rise. Importantly, loss of arm function occurs in up to 85% of stroke survivors, with a significant long-term impact on activities of daily living, leisure activities and work. The capacity for recovery following a stroke depends on several factors, including the extent of the initial neurological damage, spontaneous recovery and rehabilitation, with possible recovery even years after the stroke. Unfortunately, accessibility of much needed rehabilitation services poststroke often remains limited, both in terms of intensity and duration, as reported in a recent report on post-stroke rehabilitation services in Quebec. Recent evidence suggests that homebased telerehabilitation (TR) is a viable approach for upper limb training post-stroke when rehabilitation services are not available. Similarly, the Canadian Best Practice Recommendations for Stroke Care update for 2013 recommends home-based patient monitoring be used when frequent monitoring is needed and face-to-face visits are not available. Hence, the investigators have developed and propose to examine the use of the VirTele system for people who have suffered a stroke who are no longer receiving rehabilitation services The VirTele system allows upper limb rehabilitation using exergames with ongoing off-line monitoring combined with online monitoring and coaching based on the self-determination theory.

Study Overview

• Status: Recruiting
• Conditions: Stroke
• Intervention / Treatment: Other: home written exercise program; Other: telerehabilitation/exergame system

Detailed Description

More specifically, the primary objective of the RCT is to provide preliminary evidence regarding efficacy of the VirTele program for upper limb motor control recovery in chronic stroke. Secondary objectives are to: i. Determine the effect of the VirTele program on upper limb function, quality of life and motivation; ii. Determine the feasibility of using the VirTele program with users at home (e.g. adherence, safety, technical difficulties, facilitators and barriers); iii. Explore the role that shared decision-making and empowerment play in exercise program adherence and progression, and in behavior modification for upper-limb use.

This study will also provide evidence of feasibility for conducting a larger-scale RCT comparing different technologies and interventions for chronic stroke rehabilitation.

A single-blind (evaluator) two-arm randomized clinical trial (RCT) is proposed for this study with participants who have had a stroke randomly allocated to: (1) 8-week training with the VirTele system.i.e. treatment group or (2) 8-week written home exercise program provided by a clinician (GRASP), i.e. exercise control group.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Other: No Intervention: Usual care; All study participants in the control group will receive an 8-week written home exercise program (e.g. GRASP) , i.e. the usual care discharge home program.	Other: home written exercise program; exercises such as picking up objects, placing objects, frequently prescribed at discharge
Experimental: Experimental: Telerehabilitation system; Participants in the experimental group will receive 8 weeks home exercise program using a virtual reality (VR) and telerehabilitation system. The intensity and choice of game for the home program will be determined by the therapist based on the patient's abilities, interests, motivation and fatigue. The patient's performance for the VR home program will be monitored asynchronously and synchronously and the program adapted to ensure it remains at an appropriate level for the patient.	Other: telerehabilitation/exergame system; Video games using the Kinect camera that are carried out using the impaired arm and monitored by a therapist by videoconferencing

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline in Upper limb motor control at 8 weeks as measured using the Fugl-Meyer Assessment-UE (FMA-UE)	Upper limb motor control is assessed using a valid and reliable outcome, scores between 0-66, higher scores indicating better motor control. measure consisting of tasks to be performed by the participant	baseline and eight weeks after intervention, as well as 1 and 2 month follow up

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline in Upper limb function at 8 weeks Impact on upper extremity use in daily activities will be using the Motor Activity Log, a self-reported measure of upper limb use	The Motor Activity Log is a questionnaire that the participant completes reporting how much the impaired upper limb is used for various daily tasks, each task is scored from 0-5 (ordinal scale, 0=do not use arm - 6=use as much as before), total score is mean of the scores.	baseline and eight weeks after intervention, as well as 1 and 2 month follow up
Change from Baseline in Upper limb function at 8 weeks using the Wolf Motor Function Test	The Wolf Motor Function test consists of tasks that are performed by the participant with the impaired upper extremity, the tasks are rated for the quality of movement and the time taken. Items are scored on a 6 point scale, from does not attempt to movement is normal. Times tests are truncated at 120 seconds. A mean score out of a maximum of 5 is calculated.	baseline and eight weeks after intervention, as well as 1 and 2 month follow up
