Abstract: The present invention provides a forearm-encircling sleeve for attenuating impact-induced shock and for ameliorating the effect of that shock on the elbow joint. The device made in accordance with the present invention provides energy-attenuating viscoelastic means that are positioned distally of the elbow joint and of the common tendon origins of the medial and lateral epicondyle heads of the humerus for attenuating impact-induced shock The energy-attenuating viscoelastic means are placed in force-receiving relationship with the forearm musculature responsible for extension and flexion of the wrist and, preferably, also that responsible for the extension and flexion of the fingers and the pronation and supination of the forearm. Means may be provided for applying a counterforce to these energy-attenuating viscoelastic means.
