Period

Built and presumably used in 1984; possibly also used later.

Canada

This example was built in 1984 and was the prototype of the lower limb CPM being manufactured by TMC in 1987. The concept of continuous passive motion [CPM], and design of CPM devices, was championed by Dr. Robert Salter, an orthopaedic surgeon at the Hospital for Sick Children and professor and head of orthopaedic surgery at the University of Toronto. One of 5 CPM devices donated to the History of Medicine Museum, Toronto by Toronto Medical Corp., Scarborough, Ont. in May 1987.

Function

Device designed to provide continuous, controlled range -of -motion action to an injured or post-surgery limb, specifically the lower limb (ie. foot, calf and/or thigh)

Technical

Based on the hypothesis that continuous passive motion would stimulate the healing and regeneration of articular cartilage through differentiation of pluripotential mesenchymal cells. CPM devices promote patient comfort, by improving circulation and encouraging wound healing, and preventing excessive post-operative swelling. This version can be battery operated, or run off the main electrical supply.
