A device for supporting a lower limb of a subject. The device has a housing for a lower limb and a limb support. The housing has a longitudinal axis aligned with a longitudinal axis of the lower limb. A driving mechanism connected between the housing and the limb support, causes movement of the limb support between a retracted position parallel to the longitudinal axis of the housing and an extended position in which the limb support extends perpendicularly to the longitudinal axis of the housing to support the lower limb.

A handheld device and method for self dry needling using the device comprising a dry needle outlet end; a needle priming cavity aligned with an outlet of the needle outlet end and configured to receive a dry needle therein for dispensing; a needle ejection mechanism comprising a driver configured to eject the dry needle from the needle priming cavity through the needle outlet upon actuation of the needle ejection mechanism; and a needle storage cavity configured to hold one or more additional dry needles comprising a needle loading mechanism configured to transfer one or more needles from the storage cavity to the needle priming cavity upon actuation of the needle loading mechanism.

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.

The disclosure relates to a therapeutic device and discloses an acupuncture device which comprises the needle gun having the gun shell, the trigger, the firing assembly, and the triggering assembly. When the trigger is in the firing state, the transmission portion is disengaged from the power output of the transmission member, and the first spring is released from the compressed state to the natural state, thereby ejecting the firing rod disposed in the chute of the firing sleeve through the elastic force instantaneously released by the first spring. Consequently, the needle can be ejected from the needle outlet by the firing rod, thereby achieving acupuncture. After the firing is completed, the trigger can be rotated to engage the transmission portion with the power output of the transmission member, thereby placing the first spring in the compressed state, switching to the reset state, and awaiting the next firing action.
