Abstract
An active and continuous passive motion (CPM) devices for exercising and/or providing therapy to the upper and lower extremities comprising a frame, a disc pivotally mounted to the frame and hand or feet support members attached to the disc. A motor is provided and is coupled to the disc for rotating the disc in the active mode. A control circuit is provided for adjusting the speed of the disc in the passive mode and for adjusting the resistance to movement of the disc in the active mode.
Claims17
A device for providing both active and continuous passive motion of upper and lower body extremities, comprising:
- a) a housing;
- b) disc means having opposite outer faces and an axis, bearing means for mounting said disc means to said housing for rotational movement about said axis, a pair of limb support members projecting laterally outward from opposite ones of said outer faces of said disc means a radial distance from said axis, said limb support members including an interchangeable pair of hand support members and leg support members, and means for adjusting the radial distance of each limb support member from said axis thereby adapting the device to permit adjustment in a range of motion of a user's limbs;
- and
- c) drive means for continuously rotating said disc means in a continuous passive motion mode of the device, and means for adjusting resistance to movement of said disc means in an active mode of the device.
A device for providing for both active and continuous passive motion of lower body extremities, comprising:
- a) a housing;
- b) a disc means having opposed outer faces and an axis, said disc means mounted in said housing for rotational movement about said axis, a pair of lower leg support members, said pair of lower leg support members being releasibly attached and projecting laterally outward from opposite ones of said outer faces of said disc means a radial distance from said axis, means adapted to adjust a range of motion for a user's lower leg by permitting the radial distance of each leg support member from said axis to be adjustable, each leg support member having a cradle portion adapted to receive and support therein the user's lower leg from the user's foot to a position spaced below the user's knee, each leg support member being pivotally attached to said disc at a drive point on said leg support member which is adapted to be between the user's knee and an ankle and below the user's calf when the use's lower leg is resting horizontally in said leg support member;
- and
- c) drive means for continuously rotating said disc means in a continuous passive motion mode of the device, and means for adjusting resistance to movement of said disc means in an active mode of the device.
