An aid device for the movement and rehabilitation hand fingers includes a exoskeleton, an articulated glove or a wearable mechanism configured to be positioned on the back of at least one finger and to be mechanically constrained to the finger, and a motorized system exerting a movement or a change in the configuration of the exoskeleton. The exoskeleton includes a rigid elements arranged on a row one behind the other along a longitudinal axis parallel to the longitudinal extension of the finger and articulated with each other to make a modular underactuated structure and obtain maximum shape and kinematic adaptability to the fingers, particularly to follow the extension and flexing movement of the fingers. The motorized system includes pulling and/or pushing elements that act on one or more of the elements of the exoskeleton to produce finger movements and particularly the extension and flexing movements of the fingers.

A powered device augments a joint function of a human during a gait cycle using a powered actuator that supplies an augmentation torque, an impedance, or both to a joint, and a controller that modulates the augmentation torque, the impedance, and a joint equilibrium according to a phase of the gait cycle to provide at least a biomimetic response. Accordingly, the device is capable of normalizing or augmenting human biomechanical function, responsive to a wearer's activity, regardless of speed and terrain.

Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

An apparatus for automated walking training includes a frame or treadmill having a driven treadmill belt and a pelvis attachment to support a position and weight of a user. The pelvis attachment includes a displacement unit for allowing a movement of the user's pelvis held by attachment elements transverse to and/or rotating about a perpendicular axis to the walking direction of the treadmill to provide a more natural and physiological gait during training. A weight suspension unit having a cable guided over a guide roller positioned above and attached to the pelvis attachment may include a displacement unit adapted to move the guide roller perpendicular to the diverted section of the cable to influence the transverse position of an upper body of the user as well as to prevent a pendulum effect of the trunk of his body.

A vibration generator comprising a mass, a coil, a permanent magnet and a housing, wherein the mass can be set in an oscillatory motion with respect to the housing by applying a current to the coil, and the vibration generator further comprising an axle, wherein the oscillatory motion is along the axle, and in that the mass comprises the permanent magnet and the coil is fixed to the housing.

A hand-attached controlled eccentric vibration device, configured to be attached to a back of a hand of a first person giving a massage to a second person receiving the massage. The hand-attached controlled eccentric vibration device includes a unit body made of rigid material in a form of a box and comprises a compartment to enclose at least one motor, a controller, and a battery therein. The bottom of the unit body has a curved shape to be fitted with the back of the hand of the first person. Further, the unit body is attached to the back of the hand of the first person by means of a skin attachment part.

A system for treating soft tissue of a patient. The system includes a treatment head and a computer portion. The treatment head includes a probe and an electrode operably coupled to the probe. The probe and electrode are configured to respectively deliver a mechanical force impulse and an electrical stimulation to the soft tissue when placed in operable contact with the soft tissue. The computer portion includes a CPU and is configured to coordinate the delivery of the mechanical force impulse and electrical stimulation relative to each other. The system is configured to sense a shockwave in the soft tissue of the patient, the shockwave resulting from the mechanical force impulse delivered to the soft tissue via the probe. The system is also configured to analyze a characteristic of the sensed shockwave and configure the electrical stimulation to be delivered to the soft tissue via the electrode based on the characteristic analysis of the sensed shockwave. The characteristic may be at least one of frequency of the sensed shockwave, amplitude of the sensed shockwave, and/or wave shape (form) of the sensed shockwave.

Examples of a device for guiding and detecting a motion of a target joints and a motion assistance system such motion guiding devices are described. The motion guiding and detecting device comprises a motion generator and a motion transfer and target interfacing unit to transfer the motion generated by the motion generator to the target joint. The system further includes a motion detection and feedback unit that interfaces with the target, and a controller that interfaces with both the feedback unit and the motion generator to control and coordinate the motion of the motion generator and the target joint.

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.
