A knee rehabilitation device is provided which can be used in various stages of knee rehabilitation to facilitate a full range of knee motion and promote joint flexibility following a knee impairment. The device, which can be used by a patient with or without the aid of medical personnel, is simple to use, compact, and is highly adjustable to accommodate different therapy regimens, and different leg sizes. To achieve maximum stretch of affected tissues of a pathologic joint, the device can be used without the need of lower extremity muscle involvement. A first embodiment device is machined or cast from a lightweight structural metal, such as titanium, aluminum or magnesium. The device includes a handle of adjustable length that is rotatably coupled to a parallel-beam leg support. The leg support provides attachment points for multiple adjustable bands that bridge the gap between the parallel beams.

In one example, a rehabilitation device includes a first element having first and second spaced-apart, generally parallel elongate members having proximal and distal ends. A second element is rotatably coupled to the first element and includes first and second spaced-apart, generally parallel elongate members having proximal and distal ends. One of the first and second elements is angularly adjustable relative to the other. A measurement device includes a measurement element connected to one of the first and second elements and configured for rotation relative to one of the first and second elements, such that when the rehabilitation device is operably disposed with respect to a joint of a patient, the measurement element is arranged for contact with anatomy of the patient. Finally, a scale is disposed proximate the measurement element and indicates a position of the measurement element relative to another portion of the rehabilitation device.

The invention relates to a knee joint rehabilitation device, which is characterized by comprising knee joint massaging brackets, knee protection wheel disc brackets, knee protection wheel disc driving motors, driving gears, driven gears, driving shafts, knee protection driving wheel discs, a pair of knee protection swinging wheel discs and hand grabs, wherein the knee joint massaging brackets are arranged on a front bracket in a splicing manner; the knee protection wheel disc driving motors are arranged on the middle parts of the knee joint massaging brackets to drive the driving gears on the two sides; the knee protection swinging wheel discs are symmetrically arranged on the two sides of the knee protection wheel disc driving motors; the hand grabs are arranged below the knee protection swinging wheel discs. According to the knee joint rehabilitation device, knee joints are massaged for physiotherapy through the hand grabs, so that blood circulation can be promoted, and muscles can be relaxed; the knee joint rehabilitation device is high in practicability, and can be widely popularized for use; core elements of the knee joint rehabilitation device are mechanical parts, so that the knee joint rehabilitation device is high in reliability and long in service life.

A knee rehabilitation exercise device comprised of a right and left leg brace, a rear knee strap, an upper leg strap assembly, a lower leg strap assembly, a portable rear brace assembly and an elastic resistance band. The left and right leg brace members are each comprised of an upper member and a lower member rotatably pinned together at the area of the knee joint. The left and right leg braces are attached to the upper and lower leg strap assembly. The rear knee strap is attached to the left and right leg braces at the knee joint. When a user places the elastic resistance band onto L hooks mounted on the upper and lower strap assembly, and the rear brace assembly is placed between the rear of the user's knee and the elastic resistance band, a resistive stretching is caused when the user straightens his leg which exercises and strengthens the user's leg muscles in the area of the knee joint.

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.

A knee rehabilitation system includes a plurality of compressible resistance members, a knee garment, and a resistance member receptacle. Each compressible resistance member in the plurality of compressible resistance members has (i) a same size and a shape as each other compressible resistance member in the plurality of compressible resistance members, and (ii) a compression resistance different from each other compressible resistance member in the plurality of compressible resistance members. The knee garment has a knee garment ventral portion and a knee garment dorsal portion. The resistance member receptacle is coupled to the knee garment dorsal portion, and the resistance member receptacle is sized to carry each compressible resistance member in the plurality of compressible resistance members, one at a time.
