There is provided a leg massager that massages a user's leg by a position-adjustable massaging system for selectively massaging massage target areas of the leg. The leg massager includes: a lower massaging system that massages a massage target area of the user's leg L including at least user's foot F; an upper massaging system that massages an upper massage target area located above the massage target area which is massaged by the lower massaging system; a driving mechanism that drives the upper massaging system and the lower massaging system; and a rockably supporting portion that supports the upper massaging system for rocking motion about its horizontal axis.

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.

An animal self-massage device includes a massage base having massage elements for contacting the body of an animal and means for releasably attaching the massage base to an animal.

This massage head includes a housing, having two active members emerging from the lower surface thereof, having its free lower edge, opposite to the housing, intended to be in contact with a patient's skin. One at least of said active members is formed of a flap hinged within the housing and capable of being pivoted to bring the lower edges of said active members closer to each other or draw them away from each other, the relative displacement of said at least one flap being ensured by means of a rotary cam formed within the housing, the rotation axis of the cam being oriented substantially parallel to the displacement direction of said at least one flap. The cam includes at least one cam track formed on its periphery, intended to cooperate with the flap support(s), having one or their ends hinged in the housing.

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.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.

A knee joint weight-bearing apparatus, which is used as a leg brace, includes an inner thigh link, an inner lower-leg link, inner extension force generation means for generating an inner extension force between the inner thigh link and the inner lower-leg link in a direction in which a knee joint of a leg extends, an outer thigh link, an outer lower-leg link, and outer extension force generation means for generating an outer extension force between the outer thigh link and the outer lower-leg link in a direction in which the knee joint of the leg extends. The inner extension force is stronger than or weaker than the outer extension force.

An adjustable length crutch including at least one support portion to support at least a portion of the weight of a user, a leg portion associated with the at least one support portion and having a foot adapted to abut the ground in use to balance the user and a length adjustment mechanism to adjust the separation between the at least one support portion and the foot to adjust the effective length of the crutch.

Disclosed herein is a leg exoskeleton configured to aid motion (e.g., walking) of a user in need thereof. In particular, the exoskeleton includes a belt configured to attach the exoskeleton to the waist of a user. The exoskeleton further includes a leg frame configured to attach to at least one leg of the user through a hip attachment mechanism on the belt. Finally, the exoskeleton includes an energy storage subsystem that is configured to store and release energy as the user walks, particularly aiding the user in the forward motion of the leg when walking. Methods of using the leg exoskeleton are also provided.

A massage device that includes a housing, an electrical input, a motor, a switch in electrical communication with the electrical input and the motor and configured to selectively provide power from the electrical input to the motor, an actuated output operatively connected to the motor and configured to reciprocate in response to activation of the motor, and a treatment structure operatively connected to a distal end of the actuated output. The actuated output is configured to reciprocate the treatment structure at a frequency of between about 15 Hz and about 100 Hz, and at an amplitude of between about 0.15 and about 1.0 inches. The combination of amplitude and frequency provides efficient reciprocation of the treatment structure such that the treatment structure provides therapeutically beneficial treatment to a targeted muscle of a user.
