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. In variations of the exemplary embodiment, the prime mover is interconnected to the coupler by at least one pivot ball received within the coupler and configured to move about multiple axes of motion. At least one finger splint is releasably connected to a distal end of the finger motion assembly and is adapted to receive a distal phalanx of the finger. The finger splint is preferably formed from a flexible sheet material that incorporates one or more stiffening, bend memory, and hypo-allergenic adhesive layers.

The continuous passive motion exercise system enables human's joints to recover speedily to original functioning after injuries or surgeries, and thus shortens the period of time needed for joint rehabilitation. The present invention provides a force or torque monitoring device attached onto a continuous passive motion exercise mechanism to measure the driving force of the repeated joint flexing and extending motion, so as to evaluate the change of the viscosity and the stiffness of the injured joints through different rehabilitation periods. This monitoring device also monitor degrees of joint muscle's active contraction and thus slows down or stops the repeated motions of exercise mechanisms to improve safety concerns. In addition, such a monitoring device also includes a data transceiver interface utilized for transmitting and receiving the information regarding a patient's states of using such a exercise system in order to assess the patient and to provide doctors with the basis for evaluating and improving the rehabilitation condition of the injured joints.

An active-passive rehabilitation device is disclosed providing natural and relatively unconstrained motion of the treated joint, which promotes drainage and mitigates edema in the extrema.

Speed, range of motion and therapeutic torque limitations are some of the parameters that may be user controlled and/or programmable. Historical data can be stored in the device and can be downloaded electronically in real-time or at discrete intervals, allowing caretakers to monitor progress and even modify load cycles via electronic communication means. The unit has a lifting provision, can be folded to accommodate storage, and has integrated stabilization and bed attachment devices.

A continuous passive motion device is provided having specific application to rehabilitative treatment of the elbow or shoulder. The device includes a motorized winch displacable in a first or second direction, a cord suspended from the winch by a variable extension length, which increases when the winch is displaced in the first direction and decreases when the winch is displaced in the second direction, and an arm harness associated with the cord. An arm of a patient is suspended from a suspension point on the cord and the motorized winch is activated to alternately displace the winch in the first and second directions, thereby providing a plurality of repetitive treatment cycles. Each treatment cycle moves the suspension point and correspondingly the elbow or shoulder from a lower treatment limit to an upper treatment limit and back to the lower treatment limit.

The present invention is directed toward a device for circumduction of a limb having a base, a vertical support operably coupled to and extending away from the base, a rotary member operably connected to the vertical support, a limb support member operably connected to the rotary member, and a motor drivingly engaged with the rotary member. The vertical support may be a rigid plate member, bracket, or frame. The bracket and/or frame may include at least one vertical member and at least one horizontal member. The rotary member is operably connected to the vertical support such that rotary member is free to rotate. Limb support member receives and supports the limb to be treated and is operably coupled to rotary member at a radial distance from a center of rotation thereby resulting in a circular motion of a limb when the motor is operated.

An exercise method and device for alleviating lower back stiffness through continuous passive motion (CPM) mimicking that experienced by a person mounted on a horse at the walk. The device and method of the present invention are envisioned as being used in gymnasiums as well as health practitioners' offices, by trainers and physical therapists treating subjects with lumbar stiffness and pain, on the one hand, and by those subjects themselves who may seek relief and greater range of motion without professional assistance. With the subject seated upright on a backless seat, with his or her spine self-supported and in proper vertical alignment, the seat is accelerated, alternatingly, forward and backward, thus imposing a horizontal to-and-fro force to the lower part of the subject's body at such frequency and excursion-amplitude that that part of the body is caused to move with respect to the upper part of the body. To permit this greater excursion of the lower body with respect to the upper, the lumbar spine bends; the resultant effect of this lumbar-spine bending is relief of stiffness--and, ultimately, discomfort--in the lumbar spine area.

A CPM chair for repeatedly flexing and extending a patient's knee permits a patient to remain comfortably seated while controlling therapeutic knee flexure and extension. A slide member is longitudinally reciprocal between extended and retracted positions with its slide direction controlled by the patent. A drum has an endless cable wrapped about its periphery and is rotated in alternate directions by a reversible electrical motor. The cable extends over respective forward and rearward pulleys and is secured to the slide member. A pedal assembly supports the patient's foot and is pivotally secured to the slide member to accommodate different positions of the patient's heel. Control switches are actuable by the patient to control slide member direction.

The invention relates to a voice signal control based upper limb function rehabilitation training system, comprising a main control module, a continuous passive motion (CPM) module, a voice module and a control panel. A user selects a voice operation mode by virtue of the control panel, a voice command is sent out and is transmitted to the voice module by virtue of a microphone, the voice module receives and analyzes the voice command, then the voice command is matched with a related control command request, and then the request is transmitted to the main control module, the main control module converts the request into corresponding control command, and the control command is transmitted to the CPM module, thus driving the upper limb of a patient to move. The system adopts a voice signal to control CPM of upper limbs, so that the patient can autonomously control the comprehensive upper limb function rehabilitation training system to complete CPM training on the upper limbs by speaking out a control command.
