Disclosed is a hand and arm support assembly for use by a user or patient to rehabilitate a hand of the patient. The hand and arm support assembly includes a hand actuator assembly and a forearm rest assembly. The hand actuator assembly provides a support for a hand engagement assembly having a housing and hand actuator rod engagement members projecting upwards therefrom to engage the hand of the patient. The housing is rotatable to accommodate the position of the patient's hand and the rod engagement members are adapted to travel along slots towards and away from one another. The forearm rest assembly includes a first carriage and a second carriage to support the forearm and elbow of the patient. The first and second carriage can pivot about an axis relative to the housing to further accommodate the position of the patient's arm and elbow.

Wearable devices and methods for preventing and treating carpal tunnel syndrome or DeQuervain's syndrome. The wearable device may include a wrist contact portion for receiving a user's forearm, a stretching mechanism configured to apply opposing forces to a first contact portion and a second contact portion to stretch the user's underlying tissue, the first and second contact portions configured to contact the user's forearm, and one or more straps configured to adjust the compressive force being applied to the user's forearm by the first and second contact portions. The first contact portion may be configured to apply a compressive force to the user's forearm at a first location. The second contact portion may be configured to apply a compressive force to the user's forearm at a second location different than the first location.

A human-computer interface system having an exoskeleton including a plurality of structural members coupled to one another by at least one articulation configured to apply a force to a body segment of a user, the exoskeleton comprising a body-borne portion and a point-of-use portion; the body-borne portion configured to be operatively coupled to the point-of-use portion; and at least one locomotor module including at least one actuator configured to actuate the at least one articulation, the at least one actuator being in operative communication with the exoskeleton.

Proposed is a rehabilitation exercise device for upper and lower limbs. The rehabilitation exercise device is characterized by including: a first support supporting a user's hand or foot; a second support supporting a user's forearm or calf; a pair of first hinges rotatably connecting the first support and the second support to each other; a third support supporting a user's upper arm or thigh; a pair of second hinges rotatably connecting the second support and the third support to each other; and a drive module selectively mounted on any one of the pair of first hinges and the pair of second hinges, and configured to pivot the first support or the second support.

A rehabilitation apparatus for wrist and forearm therapy comprising an adjustable armrest, a motor, and a rotatable base having a plurality of sockets for engaging a plurality of handles for different types of therapy, wherein the motor is configured to move the rotatable base.

An assist garment is configured to be worn on a part of a human body and includes a plurality of garment-fitting actuators placed linearly along at least one end portion of a garment body and configured to be driven to extend and contract, a plurality of assisting actuators placed linearly on the garment body to cross the plurality of garment-fitting actuators and configured to be driven to extend and contract, and a controller configured to individually control driving of the plurality of assisting actuators and driving of the plurality of garment-fitting actuators.

A pneumatically-actuated soft robotics-based variable stiffness haptic interface device for rehabilitation of a hand includes a body having a flexible outer wall and a cavity defined by the outer wall, the outer wall including a plurality of grooves configured to receive a fiber wound around the outer wall. The device further includes a pneumatic actuator in communication with the cavity and configured to provide pressure to the cavity.

An apparatus is provided that stabilizes an applicator in response to the motion caused by a user, comprising: a receiver configured to be coupled with a cosmetic applicator; at least one sensor configured to detect a movement caused by a user; circuitry configured to determine a compensation movement to offset the detected movement; and at least one motion generation device embedded in the receiver configured to control a motion of the cosmetic applicator according to the determined compensation movement.

A therapeutic bracelet includes a strip of elastomeric material that defines an interior surface, an exterior surface, and a plurality of finger holes extending through the strip. The strip of elastomeric material is configured to be positioned over an operative hand of a user and to be worn around a wrist of the user. Upon periodic removal of the therapeutic bracelet from the wrist, the user inserts one or more digits in the finger holes from the interior surface and stretches the therapeutic bracelet with a thumb of the operative hand or with an opposite hand. A method of using the therapeutic bracelet to alternately strengthen and stretch the operative hand is also provided. The bracelet may also be used for supporting the wrist in an ergonomically correct position; and, when turned inside out, for massaging sore or injured muscles.

A kinematical chain (100) for assisting a spherical motion of an anatomical joint (200) of a finger of the hand (210) of a user, said anatomical joint (200) having centre of rotation P and being arranged for allowing a relative motion of a finger of the hand (210) with respect to a portion of hand (220) of the user, said finger of the hand (210) defining a longitudinal direction δ. The kinematical chain (100) comprises a first rotational joint (110) engaged to the finger of the hand (210) and to a first connection link (115), said first rotational joint (110) arranged to provide a relative rotation α between the first connection link (115) and the finger of the hand (210) about a rotation axis x coincident with the longitudinal direction δ. The kinematical chain (100) also comprises a third rotational joint (130) engaged to the portion of hand (220) and to a second connection link (125), said third rotational joint (130) arranged to provide a relative rotation γ between the second connection link (125) and the portion of hand (220) about a rotation axis z integral to the portion of hand (220). The kinematical chain (100) comprises then a second rotational joint (120) engaged to the first connection link (115) and to the second connection link (125), said second rotational joint (120) arranged to provide a relative rotation β between the first connection link (115) and the second connection link (125) about a rotation axis y. The rotation axes x, y and z intersect in a centre of rotation O, in such a way that the kinematical chain (100) allows a spherical motion of the longitudinal direction δ with respect to the portion of hand (220) about the centre of rotation P.
