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.

A wire-driven wrist three-degree-freedom training mechanism comprises a wrist executing mechanism, a wrist linking mechanism, a forearm mechanism and an elbow linking mechanism, and adopts a wire-driven design, through comprehensive utilization of two rotation pairs in the training mechanism, wherein wrist three-degree-freedom passive training is realized through two driving motors. By way of the implementation of the wire-driven wrist three-degree-freedom training mechanism, a patient can adopt a passive training manner to perform rehabilitating training of the upper limbs. The wire-driven wrist three-degree-freedom training mechanism includes a position compensation mechanism and can be adapted to individual differences of patients.

The present disclosure relates generally to a massage device, for example, suitable for massaging the muscles of a person. The present disclosure relates more particularly to a vertical massage device including a vertical track, a carriage coupled to the vertical track, a massage component disposed on the carriage, and a drive that is connected to the carriage and configured to move the carriage along the vertical track.

An orthopedic device for supporting a lower back of a user includes a mechanical energy store, a pelvic element, an upper body element with a first force transmission element and an upper leg element with a second force transmission element The upper leg element is arranged on the pelvic element such that it can be swivelled about a first swivel axis, the upper body element is movably arranged relative to the pelvic ele-ment, the first force transmission element can be engaged and disengaged with the second force transmission element by moving the upper body element relative to the pelvic element, and the mechanical energy store can be charged and discharged by swiv-elling the upper leg element relative to the upper body element when the first force transmission element is engaged with the second force transmission element.

A robotic orthosis device (10) for assisting a user to rotate their wrist is disclosed. The robotic orthosis device includes a pair of fabric-based helical actuators (26, 28) and a sleeve (12) or rigid interfaces (90, 92) configured to attach to a user's forearm. Each of the helical actuators includes a cylinder (30, 30′) and a pneumatic bladder (40) configured to inflate the cylinder. Each cylinder includes an anisotropic sheet material (32) and a base sheet material (34) running the length of the cylinder. The anisotropic sheet material comprises elastomeric strands (74) that enable the material to stretch in a preferred direction. This preferred direction is parallel to the orientation of the elastomeric strands, but different than the longitudinal axis of the cylinder. The base sheet material, which is affixed to the anisotropic sheet material, is strain-limiting along the longitudinal axis. When the bladder is pressurized, the expansion of the bladder causes the cylinder to stretch and twist, thus generating a helical force on the user' wrist relative to the elbow.

A hand-held massage device includes a housing, a first turning plate, a second turning plate, an output rod, and a driving assembly. The housing includes an opening. The first turning plate is accommodated in the housing. The first turning plate has a concave-convex surface. The second turning plate is disposed between the opening and the first turning plate. The output rod is inserted in the second turning plate and rotated with the second turning plate. One end of the output rod is inserted to the opening and another end is abutted to the concave-convex surface. The driving assembly is connected to the first turning plate and the second turning plate. The driving assembly drives the first turning plate to rotate, drives the second turning plate to rotate or simultaneously drives the first turning plate and the second turning plate to rotate.

A derma roller apparatus is provided. The derma roller apparatus has a handle, an inner stabilizer, and a head connected to the handle via the inner stabilizer. The head includes an axial member positioned transverse to the handle. Furthermore, the head includes a left cylindrical member positioned around the axial member to the left of the inner stabilizer, and a right cylindrical member positioned around the axial member to the right of the inner stabilizer. The head also includes a first plurality of needles situated around the left cylindrical member, and a second plurality of needles situated around the right cylindrical member.

Mobility assistive devices in the nature of canes, staffs or walking sticks are constructed with a bent or “dog-leg” shape so that an upper portion of the cane adjacent the handle extends forward in the direction of travel of the cane's user and is visible in her peripheral vision. The shape of the cane and the proprioceptive feedback from its motion convey more information to the user and allow more confident, efficient motion than a traditional straight cane or staff. Some embodiments include rotating joints to allow the cane to be folded when not in use.

A wearable neck brace uses, for example, only three actuators but provides natural motion of the head and neck. This is achieved despite the fact that the head has six degrees of freedom including 3 translation and 3 rotation. In embodiments, a wearable neck brace actively controls the head of the wearer responsively to commands from a user interface such as an eye tracking input device. In further embodiments, a force-field is generated by actuators to provide assistance and/or training for weak muscles. Spring compensation may be provided for a passive support with flexibility. Encoders may be provided to generate treatment logs to support analysis of a patient's condition or progress or to provide therapy-facilitating (or athletic training-facilitating) feedback to the user.
