A user-actuated dynamic tension traction device is disclosed. According to various embodiments of the present disclosure, a traction device passively applies traction force to a user through the use of one or more rubber or elastic resistance bands coupled to a neck collar worn by the user. The resistance bands are anchored to a stationary surface (in a preferred embodiment a door). Traction is passively applied to the user, rather than actively, as the user moves his or her body away from the surface to which the resistance bands are anchored. As the user moves backward and stretches the resistance bands, tension is incrementally exerted by the resistance bands on the neck collar, and traction is gradually applied to the user's spine.

An apparatus for treating a body part of a patient is provided. The apparatus comprises a support for at least partially supporting and holding the body part and a manipulator connected to the support for supporting and maneuvering the support. The manipulator includes a parallel linkage device including a plurality of hingedly interconnected linear actuators. The parallel linkage device includes at least one hinge including a, preferably resilient, tendon joint. Further, a method, a storage medium and a piece of headgear are provided.

An actuator unit of the present invention includes upper and lower frames respectively connectable to a thigh frame and a lower leg frame, an actuator-side rotational connecting part connecting both frames in a rotatable manner around a pivot axis, a driver producing driving force for rotating the lower frame around the pivot axis, upper and lower connecting bodies respectively connecting the upper frame to the thigh frame and the lower frame to the lower leg frame, and an intermediate connecting body connecting the vicinity of the actuator-side rotational connecting part to the vicinity of a brace-side rotational connecting part, the intermediate connecting body having a ball stud and an accommodation depression respectively provided on one and the other of the knee-ankle-foot orthosis and the actuator unit.

In one aspect, an orthosis for increasing range of motion of a body joint generally includes first and second dynamic force mechanisms for simultaneously applying a dynamic force to body portions on opposite sides of a body joint.

Provided herein are devices and methods for analysis and/or exercise of a body region of a subject. Such devices may include a guide arm supported by a support frame; a receiving surface supported by the guide arm, the receiving surface for receiving input force from the subject; and a motor assembly in communication with the guide arm, the motor assembly controlling movement of the receiving surface based on received input force. Exercise and/or analysis methods described herein may include steps of instructing the subject to apply an input force to a receiving surface; sensing the applied input force over time; and controlling movement of the receiving surface based on the received input force using a motor assembly, whereby the motor assembly moves the receiving surface in a pre-determined direction, so long as the input force remains within an allowable tolerance, until a pre-set end position is reached.

A foot stretching/checkup device includes: a motor unit; a footrest unit including a lower footrest configured to be rotated about a first rotation axis, an upper footrest configured to be rotated about a second rotation axis and a connecting member connecting the upper footrest and the lower footrest; and a coupling unit including an arm portion rotated by the motor unit and a rotary coupler coupled to the upper footrest. The upper footrest is configured to be rotated by a predetermined angle about the second rotation axis by the rotation of the arm portion. The lower footrest is configured not to be rotated about the first rotation axis by rotation of the arm portion until the upper footrest is rotated by the predetermined angle.

An orthosis for stretching the tissue around a foot and a toe of a wearer includes a first member affixable to the foot and a second member operatively connected to the first member and affixable to the toe. A gear is connected to the second member and rotates relative to the first member to impart movement of the second member relative to the first member. A drive assembly is operatively coupled to the gear and drives rotation of the gear, thereby driving movement of the second member relative to the first member such that the toe moves relative to the foot.

An exercise assist device transitively moves a sacroiliac joint in a lateral decubitus position. The following description is provided in the context of a left lateral decubitus position. The upper right leg is placed on a stand in the lateral decubitus position, and the upper right leg is then extended transitively backward with a sacral area supported by a sacrum support pad. Since a posterior side of a lower left sacroiliac joint is slightly opened, a sacrum slides backward via a right hip joint. This improves mobility of the lower left sacroiliac joint.
