A body interface comprises a panel, and a lumbar support and may be configured to attach to an exoskeleton such as a leg/hip assist mechanism. The body interface has an adjustable tension provided by either a tensioning device or by the properties of materials in the panel and the lumbar support. Tension in the body interface allows the lumbar support to comfortably and dynamically contact a user's body while the panel cooperates with the leg/hip assist mechanism. First and second arms may extend from lateral portions of the panel to define with first and second belt members a circumference around the user.

A portable therapeutic device includes a portable body having a recessed central region and a raised outer peripheral edge surrounding the recessed central region and directly engaged with the recessed central region, a plurality of massage balls seated at the recessed central region and spaced inside a perimeter of the raised outer peripheral edge, a thermal-conductive element channeled inside the outer peripheral edge and spaced from the recessed central region, and a power source communicatively coupled to the massage balls and the thermal-conductive element.

A human interface device is configured to be coupled to a trunk of a person and comprises a frame, a fabric coupled to said frame configurable to be under tensile forces, and a belt configured to be coupled to two side edges of said frame wherein when said belt is worn by said person, an area of said fabric will be pushed against the person's lower back conforming to the shape of the lower back of said person. In operation when said human interface device is worn by said person, the weight of any load coupled to or supported by said frame will be partially supported by the friction force between the area of said fabric which is pushed against the person's lower back, and the person's lower back allowing said person to carry said load.

A lumbar traction arrangement, comprising movement means arranged to receive a sitting person and arranged to allow movement of the person, and traction means operatively coupled to the movement means causing variable vertical traction to the person's lumbar during movement provided by the movement means.

A vibrating back massager with guide slot and vibrating heads is described. The guide slot is designed to restrict lateral movement of the massage device when the guide slot is engaged with a supporting member. The supporting member may be the edge of an open door, a corner, a vertical pole, or other generally available structure. The device includes a strap handle which may be draped over the user's shoulder and used to control the vertical position of the device. The described vibrating massage device allows a single user to create and maintain a significant amount of massage pressure without fatiguing his arms or relying on a second person. In a preferred embodiment, the controls for the vibrating massage device are incorporated into the strap handle so that the speed, intensity, and/or temperature may be controlled by the user without repositioning the device.

Some implementations can include a mechanical passive exoskeleton for the support, endurance, and physical health of laboring workers, operators with reduced strength in extremities, and operators in need of assist when rising to a standing position. The exoskeleton can assist in bending, crouching, lifting, and other repetitive motions via resistance within the flex chain and flex cartridge assemblies and lumbar support from the resistive nested spinal assembly.

A device is described for delivering a therapeutic vibration to a body. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal.

An integrated lower back treatment system is provided. The system includes a central core. The system also includes attachment devices positionable on longitudinal ends of the core. The system further includes a strap, wherein an end of the strap connects with a longitudinal end of the core with the attachment device and an opposite end of the strap connects to an opposite longitudinal end of the core with another attachment device. Additionally, the system includes padding, wherein the padding assembly includes padding arranged to allow the padding to connect and form a shape over the core and wherein the padding has differing firmness characteristics such that when the padding is rotated about a longitudinal axis of the core, a user of the integrated lower back treatment system will experience different firmness values dependent upon a position of the rotated padding on a lower back of the user.

An orthopedic standing and walking aid and a method of supporting a person with such an orthopedic standing and walking aid. The orthopedic standing and walking aid comprises a carriage which is displaceably mounted on a running rail, an approximately C-shaped frame suspended from the carriage by a suspension device and a saddle which is arranged on the shaped frame approximately in linear alignment below the suspension device. The orthopedic standing and walking aid can be distinguished by a spring element arranged in the area between the carriage and the saddle so that the saddle is elastically supported in the vertical direction. The orthopedic standing and walking aid may also be distinguished by a height adjustment mechanism for adjusting the height of the saddle, which has a height adjustment spring element which exerts an upward preload on the saddle. This height adjustment mechanism can be designed to be lockable with one hand by means of a locking unit.

An exoskeleton structure includes a back assembly, an arm assembly, and a shoulder connection device. The shoulder connection device includes a first connection part, a first pivot connecting the first connection part to the back assembly while allowing rotation of the first connection part around a first axis of rotation, a second connection part, a second pivot connecting the first connection part to the second connection part while allowing rotation of the second connection part around a second axis of rotation orthogonal to the first axis, and a third pivot connecting the second connection part to the arm assembly while allowing rotation around a third axis of rotation orthogonal to the second axis of rotation. The second pivot is arranged so that the second axis of rotation forms a non-zero angle with an abduction/adduction axis of the shoulder and a non-zero angle with a flexion/extension axis of the shoulder.
