The length adjustment device and adjustment method having a finger motion rail that is automatically moved along an adjustment rail by a drive on a therapeutic device and allows the finger motion rail to be fixed on the adjustment rail and therefore on the therapeutic device at a desired position in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or of a thumb of a hand in a stable position.

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.

The present disclosure relates to a device including electrostatic brakes providing haptic kinaesthetic feedback to a user in e.g. assistive, rehabilitation or virtual reality scenarios, as well as tele-manipulation.

A device comprising at least two ferrules, which may have a first ferrule (3) and a second ferrule (4), joined by elements by programmable elastic means (5) in the manner of elastic rods or straps with shape memory, wherein each ferrule (3) (4) has a housing (3.1) (4.1) for housing vibration-generating means (6) and (7) fed by means of cables (6.1) and (7.1), respectively, by a control unit which is in charge of controlling and adjusting vibration intensity, phase and speed, wherein the programmable elastic means is preferably a nickel-titanium alloy, and may be compressed air. A device is obtained that is simple to implement and apply in the treatment of arthritis and arthrosis disorders.

The present disclosure provides an electrohydraulic device. The device includes a battery having a vessel containing a flowable electrolyte. The battery may be a flow cell battery, such as, for example, a redox flow cell battery. In a flow cell battery, the flowable electrolyte may a catholyte and/or an anolyte. An actuator is in fluidic communication with the vessel of the battery. The actuator is configured to be actuated using the flowable electrolyte. A cation exchange membrane may separate the vessel into an anolyte side and a catholyte side. The actuator may be in fluidic communication with either side (anolyte side or catholyte side) of the vessel.
