Abstract: A continuous passive motion apparatus for therapeutic treatment of the fingers of a patient's hand that includes a forearm hand splint. A drive unit is mounted on a palmer aspect of the splint and incorporates a motorized drive tube actuatable over a selectable range of motion. A flexion and extension assembly is connected to the tube and includes at least one finger motion assembly. The finger motion assembly is pivotally interconnected to a proximal end of the drive tube by a coupler adapted to enable movement in at least 2 degrees of freedom relative to the coupler. The coupler is further adapted to releasably engage the at least one finger motion assembly after adjustment to optimally accommodate the anatomical arrangement, size, and range and path of motion of the fingers. The finger motion assembly includes a resilient prime mover selected to be repeatedly bendable without damage but with a bend memory so that it can be adjusted to have an angle of up to about 90 degrees.

Abstract: A continuous passive motion device comprises a leg support frame actuated by alternately, pneumatically inflating and deflating a bladder assembly. The assembly includes a series of interconnected bladders associated with a pump and a three-way solenoid valve, and provided with flaps secured at a common point which act as a hinge. The secured flaps force movement of the bladders in an arcuate path during inflation and deflation, providing an operating force against pivotal components of the device thus actuating it. A photointerrupter control device is provided that controls the angular limits of the desired therapy.
