Context

Country: Canada
State/Province: Ontario
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: Unknown
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.
Area Notes: Unknown
