Recently, we were confronted with the problem of providing a method for mobilization of contractures in both hips and knees of a patient in whom none of the usual orthopedic or physical therapeutic techniques was applicable. The problem was successfully solved with the aid of a simple traction device that was built in a short time without the use of complicated machinery. The purpose of this paper is to make generally available the knowledge of this additional, easily constructed physical therapeutic aid.
The construction of this device is illustrated diagrammatically in figure 1. We used a masonite ® board ⅜ in. by 16 in. by 18 in. and two pieces of plywood, each ½in. by 6 in. by 6 in. The latter were made into two small carriages by attaching four small metal wheels to each. The wheels could spin freely because friction was low. The carriages moved easily with
