Abstract: A therapeutic device for use by a patient in developing fine, medium and gross motor arm movements. The device can be clamped to a stationary surface such as chair or desk and includes outwardly extending upper and forearm members. They are pivotably joined for movement through prescribed angles at joints partially simulating the joints of the arm. The joints each include selective resistance adjustments that enable a selective resistance to be applied at each joint according to the needs of the patient. A grip member at an outer or distal end of the forearm member is grasped or otherwise attached to the patient's hand during use. Movements of the hand and arm effect corresponding movements through the joints of the device. The device thus acts to dampen sudden movements and exercise selected muscle groups while moving in direct response to movement of the user's arm.

Abstract: A therapeutic educational tracing device consisting of a transparent panel having an eraseable surface, a transparency bearing indicia removably disposed to underlie the panel, a rearwardly disposed mirror angled to reflect the indicia and thus enable a child tracing the indicia to perceive his hand and the indicia in the mirror and perceptually guide his hand in tracing the indicia by a mental process.
