Period

This prototype device built in 1978, for experimental purposes. Never used on/by patients.

Canada

Prototype CPM machine for hand built by Craig Pon, a student at the University of Toronto. in 1978. This version was never actually used on a patient, but was the forerunner of the later devices. 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

Prototype version of device designed to provide continuous, controlled range -of -motion action to an injured or post-surgery limb, specifically the hand.

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.
