An air inflatable massage cushion contains: a body and a control box which is connected with the body via the multiple air tubes. The body includes multiple airbags communicating with at least one air channel via multiple air conduits, wherein a respective air channel is in connection with some of the multiple airbags, different air channels are connected with the multiple airbags which are intersected with one another. A respective one airbag does not communicate with at least one adjacent airbag so as to inflate or deflate airs in some airbags not communicate with one another via different air channels, thus inflating and deflating the airs of the airbags at different positions of the body to obtain air permeability and a massage effect.

A hand rehabilitation device, a rehabilitation training device, and a method for controlling the same are disclosed, and the hand rehabilitation device includes a hand rehabilitation component including: a glove; a hand pneumatic muscle group including at least one finger pneumatic muscle component, wherein a back of each finger sleeve in the glove is installed with at least one of the at least one finger pneumatic muscle component; and a stopper which is connected with each finger sleeve and a side of each of the at least one finger pneumatic muscle component facing a corresponding finger sleeve.

A device for applying air pressure to a portion of a body of a person is provided. The device includes a garment configured to be arranged distally of a joint of the body of the person, wherein the garment comprises a plurality of hollow rings configured for arrangement along a longitudinal axis of the portion of the body of the person, each of the plurality of hollow rings having a skin contacting surface and an air contacting surface, the skin contacting surface including a series of holes for supplying air directly to skin of the portion of the body of the person.

A system for treatment of involuntary muscle contraction includes a wearable interface having an internal contact surface, the wearable interface configured to at least partially encircle a first portion of a limb of a subject, and an energy applicator carried by the wearable interface and configured to apply energy of two or more types to the limb of the subject. The system may further comprise a control unit configured to control the operation of the energy applicator.

A training apparatus is disclosed, comprising: a top structure, a bottom structure, and a traction structure disposed between the top structure and the bottom structure, and wherein the traction structure is configured to be retractable along an axial direction of the top or bottom structure to achieve relative movement between the top structure and the bottom structure.

Systems and methods for a wearable exoskeleton include an inflatable actuator with a reduced operation volume for faster operation. The inflatable actuator may include a first paddle connectable to the human body, a second paddle connectable to the human body, and an inflatable fabric coupled between the first paddle and the second paddle. In response to the inflatable fabric being filled with compressed air, the rigidity of the inflatable fabric increases, causing the angle between the first paddle and the second paddle to change to provide an assistive force for a movement of the human body. A portable pneumatic source is provided for quickly supplying a compressed air to the inflatable actuator. The portable pneumatic source may include a double acting piston and a cylinder defining a first chamber and a second chamber, and a valve assembly, for compressing air at both the upstroke and downstroke of the piston.

Embodiments provide devices, systems and methods for preventing deep vein (DV) thrombosis (DVT). One embodiment provides a DVT prevention device including a cuff that fits over a patient's knee, an applanator coupled to an inside cuff surface, an expandable member (EM) coupled to the applanator, a pressure source fluidically coupled to the EM and a controller for controlling EM inflation. When the EM is inflated, it applies a force to the applanator which is transmitted to the knee back surface causing a popliteal vein (PV) under the cuff to be compressed so as to increase backpressure behind the compressed PV and subsequently increase the velocity of blood flow in the leg DV's when the EM is deflated. The EM can be inflated in a cycle including pulsed inflation, inflation hold and relaxation. The cycles can be repeated and adjusted to achieve a desired increase of blood flow/velocity in leg DV's.

A stimulation device is provided in accordance with one embodiment. The stimulation device includes a chamber which has a flexible wall portion. A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber. The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. An opening of the stimulation device is for applying the modulated positive and negative pressures to a body part. The stimulation device includes a control device for controlling the drive unit.

A health-regain device includes a driving portion, a health portion disposed on one side of the driving portion, and a control module communicably connected to the driving portion, wherein the control module controls the driving portion driving the health portion in rhythmic reciprocating motion.

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.
