Examples of a self-supported device for guiding motions of a target joint of a target body are disclosed. The device comprises a motion generator, a motion transfer system, a target body interfacing system, a load bearing system and a controller. The load bearing system comprises a plate connected to the motion transfer system and a network of joints and links configured to constrain the plate to rotate in three dimensions about a center of rotation of the load bearing system. A position of the center of rotation of the load bearing system being adjustable by adjusting a connection point between the links. The plate of the load bearing system is connected to an adjustable target body interfacing system that is configured to be mounted to the target body. The center of rotation of the load bearing system coincides (or nearly coincides) with a center of rotation of the target joint of the target body.

An automatic acupuncture device includes: a case; a motor or an electromagnet; a needle driver, configured to move linearly under the force of the motor or electromagnet to drive an acupuncture needle in a needle gadget into a human body, the needle gadget comprising a needle tube and an acupuncture needle inside the needle tube; a needle gadget chamber configured to house the needle gadget; and a locking-releasing structure that is configured to lock the needle gadget so that it will not fall out of the needle gadget chamber during acupuncture treatment, and also configured to release the needle gadget from the needle gadget chamber after acupuncture treatment. A needle gadget is provided for use with the acupuncture device, so that the acupuncture needle will not be exposed in air outside the needle tube before or after acupuncture. The acupuncture process is automatic, safe, without complicated manual operation.

A method of controlling a drive motor for a powered ankle exoskeleton is disclosed. The method includes modeling motor drive current as a linear function of desired torque and ankle angular velocity, and then controlling motor current as a function of measured torque and determined ankle angular velocity.

A wearable focal vibration device for providing vibration therapy to a patient includes a control module, a vibration module and a vibration sensor. The vibration module is configured to output a vibration in response to a command signal from the control module. The vibration sensor is configured to output a signal to the control module representative of the vibration measured by the vibration sensor. The wearable focal vibration device may also include a harness for attaching the wearable focal vibration device to the patient. The harness can include a compression mechanism and a compression sensor for ensuring that the focal vibration device is sufficiently and consistently secured to the patient.

A percussive massaging device has a base which includes a tool receiver and a piston for providing percussive action to a massage tool. The massage tool includes an attachment for selectively attaching to the tool receiver using one of a key and keyway system and a magnetic system. The attachment post further includes a press-fit seal or a magnetic mechanism for further securing the attachment post to the tool receiver. The massage tool further includes a tool head which may be non-rotating or is capable of rotating in one or more directions during use while simultaneously providing a percussive massage to a user.

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 fascia tissue fitness device may include a structural member, at least one fascia tissue treatment element configured to be moved relative to the structural member, a translation member supported by the structural member onto which the at least one treatment element is affixed, and an actuator coupled to the translation member. The actuator may be configured to cause the translation member to repeatedly move back and forth relative to the structural member such that the at least one fascia tissue treatment element moves back and forth to treat fascia tissue of a user. A pressure sensor may be configured to sense pressure being applied to a user by the at least one fascia tissue treatment element.

A personal therapy device, directed generally to an elongated sexual stimulation device for female use having advanced shape motion control and shape transformation. In one embodiment, the device has a flexible outer body elongated in a longitudinal direction and a shape memory alloy (SMA) thrust actuator disposed within the flexible outer body. In another embodiment, the device includes one or more skeletal segments which are disposed within the flexible outer body and capable of deformation in various directions. In yet another embodiment, the device includes one or more rotational servo motor pair units, where each rotational servo motor of the rotational servo motor pair has an eccentric weight, and the synchronized rotation of the eccentric weight pair generates a net lateral wobbling motion. In yet another embodiment, the device includes an external positioning sensor unit, an inertial measurement unit, one or more pressure sensors, or a combination thereof.

The plantar flexure muscles assist device includes at least one drive mechanism (10) having a linear drive actuator (26); a latch mechanism (25) having a toothed annular surface coupled to the linear drive; a retractable rotating element having a toothed drum (24) and an elastic spiral element (23). The toothed drum has an annular groove and where the toothed drum corresponds to the toothed lock mechanism; a rope (28) wound in the annular groove of the toothed drum with one end attached to the elastic element (2); and a casing (21, 27) for containing the elements of the drive mechanism; a control system to send a signal to the linear actuator to activate or deactivate the locking mechanism, and a battery to supply power to the control system. The lightweight activation mechanism, together with the lightweight structure, allows the elastic element to store mechanical energy while the dorsiflexion movement occurs. This energy will enhance the plantar flexion movement, to increase physical performance on long and demanding walks and decrease user fatigue.

A hip traction device, system, and associated methods are disclosed. Such a device may include a base having a proximal end and a distal end, a guide coupled to the base, a carrier configured to move along the guide upon receiving a force from a tensioner to move the carrier toward the distal end of the base, causing a leg to be put in tension, and a single body coupling mechanism either removably attachable or permanently attached to the carrier and configured to securely attach to a lower portion of a leg, such that the portion of the leg moves with the carrier during operation of the tensioner.
