Your doctor and therapists should have this article before you ask about it, you do expect them to be up-to-date and competent Don't you?
Then why didn't they have it? What excuse did they use?

This paper presents a new sensing and interaction environment for
post-stroke and upper extremity limb rehabilitation. The device is a
combination of camera-based multitouch sensing and a supporting
therapeutic software application that advances the treatment, provides
feedback, and records a user's progress. The image-based analysis of
hand position provided by a Microsoft Surface is used as an input into a
tabletop game environment. Tailored image analysis algorithms assess
rehabilitative hand movements. Visual feedback is provided in a game
context. Experiments were conducted in a sub-acute rehabilitation
center. Preliminary user studies with a stroke-afflicted population
determined essential design criteria. Hand and wrist sensing, as well as
the goals of the supporting game environment, engage therapeutic
flexion and extension as defined by consulted physicians. Participants
valued personalization of the activity, novelty, reward and the ability
to work at their own pace in an otherwise repetitive therapeutic task. A
"character" - game element personifying the participant's movement -
was uniquely motivating relative to the media available in the typical
therapeutic routine.
