The biggest hit

Stroke causes significant damage to the brain and often results in severe weakness on one side of the body. Survivors are likely to compensate for the loss of function through an increased use of the less affected arm and the nonuse of the affected arm. In some cases, this can be overcome through constraint-induced movement therapy (CIMT) by restraining the less affected arm to require the use of the affected arm when performing tasks. This research project investigates how a tangible interface in the form of an interactive radio could facilitate the restraining effect of CIMT. I used a research through design methodology that led to the design of an interactive radio that restrains the movement to one specific side of the body. The usability of the design was assessed by stroke therapists. Feedback indicated that the radio has potential in restraining the movement while encouraging a repetitive movement of the affected arm, but does not deliver CIMT.
