E-dumbbell: An electronic dumbbell with haptic feedback for wrist rehabilitation

In this paper, the design and implementation of a wrist rehabilitation system that is cheap and simple is presented. E-dumbbell consists of a regular dumbbell mounted with an accelerometer and a pair of vibro-tactile actuators that allow the dumbbell interface to interact with a two dimensional Ping-Pong game. The main purpose of the system is to enable patients to perform their daily wrist training in a convenient and entertaining manner. The system can be adapted to fit the needs of different patients with different rehabilitation levels by allowing patients to customize the difficulty level of the game. The training sensory data are stored in a database that could be used by the therapist to track his/her patient´s progress.
