Continuous passive motion is a physical therapy technique to encourage the repair of damaged cartilage by improving the circulation of synovial fluid in a synovial joint. CPM is an important stimulus to joint regeneration processes. The concept was created by Robert B. Salter M.D in 1970 and, along with help from engineer John Saringer, a device was created in 1978. Synovial fluid is a thin, stringy fluid found in the cavities of synovial joints. ... Synovial joints (or diarthroses, or diarthroidal joints) are the most common and most moveable type of joints in the body. ... Robert Bruce Salter C.C. , M.D., D.Sc. ...
