[BLOG POST] Home After a Stroke: Reviewing Virtual Reality Rehab

Between September 2011 and May 2017 Dean published 173 posts about the use of virtual reality to provide rehab for stroke survivors.  The results for the hand are depressing.  For six years research focused on a subject’s ability to touch an object on the screen so the computer can move an object or make it disappear.  Enjoying these quick reactions is not enough to justify the cost of this expensive equipment.  It was a good place to start 6 years ago, but progress towards useful gains is disappointing.  Stroke survivors want to manipulate objects with their hand.

There is a glimmer of hope.  Gauthier (1) used video games that make stroke survivors do more than use their shoulder and elbow to reach forward and side to side.  These games require forearm and wrist motions.  This may not sound exciting but these motions orient our hand to the many different positions objects rest in. The photo shows the forearm is halfway between palm up and palm down so the hand can pick up a glass.  Cocking the wrist means the rim of the glass is not pointed at the ceiling but at the person’s mouth.

Unfortunately, Gauthier selected stroke survivors who already had a few degrees of active forearm and wrist movement.  How can subjects make the leap from just reaching to turning their hand palm up to catch a parachute on a video screen?  My OT gave me exercises that helped me regain forearm and wrist motions.  These small motions have made me more independent.  For example, I can turn my hand halfway between palm up and palm down to grab my cane so my sound hand can catch the door before the person in front of me lets it slam shut.  I picture stroke survivors practicing forearm and wrist motions and then immediately trying to turn their hand palm up so they can turn over a card on the computer screen. Fun + repetition is good.
