In some embodiments, a balance board comprises a base plate for positioning the balance board on a surface, a platform coupled to the base plate via one or more adjustable couplings configured to allow changing a stability of the platform. In the balance board, the platform is configured to undergo a tilt in response to a torque applied to the platform; increase a magnitude of the tilt by a tilt increase in response to an increase in a magnitude of the torque by a torque increase; and upon decreasing the stability of the platform, increase a magnitude of the tilt increase in response to the same torque increase.

A device for multidimensional mobilization of lumbar, pelvic, and hip joints with a generally concave upper surface connected to a generally convex lower surface is disclosed, wherein the generally concave upper surface has a recess to cradle a sacrum.

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.

In an exercise system including a platform designed to undergo an inclined or declined precession like movement relative to a ground base, a method of limiting the translational movement of the platform and increasing its general stability, the method including the step of: (a) providing at least one slot and corresponding knob, with the inclined movement of the platform causing the movement of the knob along the slot. The system is particularly suited to bed treatment arrangements.

An apparatus and method for training muscle strength and mobility in the neck provides a dynamic resting position without pressure on the neck, of a person when in lying position. The apparatus includes a base element, a head support suspended floating above the base element, and a neck support rising from the base element. The neck support provides a fulcrum that defines head movement to a pivoting motion about a first axis (X) which runs sideways substantially along the shoulder line of the body, a pivot connection between the head support and the base element defines head movement to a pivoting motion about a second axis (Y) transversely to the first axis, and by its floating suspension the head support defines head movement to a pivoting motion about a third axis (Z) running in the longitudinal direction of the neck and body.

A treatment unit includes a treatment part including a treatment element, a first drive unit including a swash plate eccentric cam and a second drive unit including an eccentric cam. One of the first drive unit and the second drive unit is connected to the treatment part, and the other one of the first drive unit and the second drive unit is connected to the one of the first drive unit and the second drive unit.

A neck and shoulder massaging mechanism includes a housing, a neck massaging assembly, a shoulder massaging assembly, an eccentric assembly, a connection assembly, and a rotating shaft. The eccentric assembly is disposed on the rotating shaft. The eccentric assembly is linked to the neck massaging assembly to perform an eccentric oscillating movement. The connection assembly includes a first spherical cavity, a ball connecting rod, and a second spherical cavity. Spherical members at two ends of the ball connecting rod are accommodated within the first spherical cavity and the second spherical cavity, respectively. The neck and shoulder massaging mechanism has characteristics of a simple structure and large eccentric oscillating amplitude.
