Abstract: The described knee rehabilitation device can include any suitable component. In some implementations, however, it includes a sitting surface that is configured to support a user; a knee arm that comprises a leg coupling mechanism, that is pivotally coupled to the rehabilitation device, and that is configured to pivot through a range of motion; and a drive mechanism that is configured to force the knee arm through the range of motion. In some cases, the drive mechanism includes a first hard stop that prevents the knee arm from extending past a first set point, and the drive mechanism further includes a second hard stop that prevents the knee arm from being retracted past a second set point. In some cases, the device is further configured to be programmed to electronically limit the knee arm's range of motion. Other implementations are discussed.

Abstract: A hand-held probe device capable of providing electro-stimulation and thermo-stimulation to a patient is described herein. While the probe device can include any suitable component, in some instances, it includes a probe head made with an electrically and thermally-conductive material. In some instances, the probe device also includes a temperature control mechanism that is configured to raise and lower a temperature of the probe head. The probe head is also connectable to an electro-stimulation unit (such as a transcutaneous electrical nerve stimulation unit) such that the probe head is able to provide electro-stimulation simultaneously with thermo-stimulation. Although the temperature control mechanism can include any suitable component, in some instances, it includes a thermoelectric device, such as a Peltier circuit. Other implementations are also described.

Abstract: Systems and methods for providing light therapy traction to a patient. A light therapy device and a traction mechanism provide concurrent, alternating and/or repetitive treatment to a patient. The light therapy device includes one or more light sources configured to deliver light to a patient. The traction mechanism is configured to provide selective separation to a particular location the patient's body, such as a location of the patient's vertebrae. In some embodiments, the light therapy and traction are performed simultaneously. In other embodiments, the light therapy and lumbar traction are performed in treatment cycles to the patient. Embodiments of the present invention embrace the application of light therapy prior to, during, and/or after a cervical and/or lumbar traction treatment.

Abstract: Systems and methods for dynamically distributing power of a light beam for use in administering light therapy. A laser light beam having a maximum peak power is selectively diffused to distribute the maximum peak power. In at least some implementations, the diffused laser light beam is attenuated across the diffused beam. Having undergone processes of diffusion and attenuation, the laser light beam is then safely used to administer light therapy on a patient. In further implementations, the diffusion includes a defocused diffusion and/or includes a distribution of power rather than an attenuation of power.

Abstract: Massage device (10) comprising head (12), which 76 defines cavity (8) and an opening to cavity (8). Head (12) has one or more contact surfaces and post (32) connected to head (12). Post (32) is positioned within cavity (8) and extends toward the opening. Post (32) also has one or more contact surfaces. Vacuum source (49) communicating with cavity (8) provides a means for creating negative pressure with cavity (8). Additionally, a method and system for performing abrasion on a surface, such as on the skin 74 of a patient, is disclosed. The dermabrasion apparatus includes means for delivering and retrieving material to and from a selected site to be abraded, a delivery and retrieval hand piece, an abrasive handling device, and a waste retrieval holding device. Hand piece (118) is coupled to the abrasive handling device as well as the waste retrieval holding device, which is further coupled to the delivery and retrieval means.

Abstract: An apparatus for treating patients using electrical interferential therapy is disclosed. The apparatus uses multiple electrodes to define multiple treatment channels, with each channel having a discrete frequency and an adjustable beat frequency between all or selected channel pairs. This adjustment can be done between treatment sessions or can be done during the treatment session by the technician or by the apparatus as programmed. The multiple treatment channels can be used on the same patient, or can be used by the same or a different technician to treat additional patient(s).

The abrasive handling device further includes an abrasive supply device, a receiving channel, a feeding chamber, and a delivery channel. The abrasive supply device typically is a canister fitted with a funnel-shaped spout that is inverted into the receiving channel. The receiving channel feeds abrasive to the feeding chamber.
