Abstract: A tremor control device is provided to control spastic movements of a person's forearm caused by cerebral palsy. The device is connected to a wheelchair or work station in front of the person by the interfitting of a horizontal travel support member into holes of an attachment device. A trolley rides along the travel support member capable of full rotational movement around the member. A forearm rest, which restrains the forearm in position is attached to a slide which slides in a lineal direction, the base support of which is connected to the trolley through an attachment that allows the full rotational movement in a plane perpendicular to that of the rotational movement of the trolley.
