Design of accelerometer based wrist rehabilitation device

Vigorous repetitive motion can damage the wrist and tend to affect patient's daily life. Thus, patient needs to see therapist to undergo rehabilitation treatment. This research proposes a rehabilitation device to help patients with wrist problem to do rehabilitation treatment at home without therapist assistance. The device uses a single hand pedal mechanism that contains an accelerometer to measure acceleration exerted by the user's wrist motion in pitch and yaw movements. Preliminary experimental results show the usefulness of the proposed device where the movement of accelerometer sensor attached on the device corresponds to the actual movement of the wrist. Furthermore, the uniqueness of this device is the portability and low-cost design.
