Force feedback system for continuous passive motion device.

摘要

A method for providing force feedback in continuous passive motion systems, for use in treating or preventing low back pain in an individual. The method comprises the steps of: providing a mechanism to initiate continuous passive motion for the spine; providing a system for measuring the force exerted by the mechanism on an individual's spine; and providing a system for controlling the force exerted by the mechanism on an individual's spine. A timer may be provided for the basic control of the mechanism. Suitable apparatus comprises, a back support (12) having a force applying section (16). The force applying section has a mechanism (13, 14, 15) for initiating continuous passive motion to an individual's back. Force measuring transducer (17) is positioned at the point where the force applying section contacts the individual's back and a logic system controls the operation of said force applying section based upon the measurements obtained from the force measurement means. <IMAGE>
