Abstract:
In at least one aspect, there is provided a system for generating force about one or more joints including a soft exosuit having a plurality of anchor elements and at least one connection element disposed between the plurality of anchor elements. The system also includes at least one sensor to determine a force the at least one connection element or at least one of the plurality of anchor elements and to output signals relating to the force, at least one actuator configured to change a tension in the soft exosuit and at least one controller configured to receive the signals output from the at least one sensor and actuate the at least one actuator responsive to the received signals.
Abstract:
A rehabilitation system with stiffness measurement on a body part to be rehabilitated is disclosed. The rehabilitation system includes a rehabilitation unit and a processor. The rehabilitation unit includes an exoskeleton brace holding a rehabilitation part of user and traction lines driving the exoskeleton brace for moving. When the exoskeleton brace moves, the processor analyzes tensions of the traction lines to obtain stiffness information relating to the rehabilitation part of user.
Abstract:
A massage apparatus includes an upright support frame and a moving seat. Each of the support frame and the moving seat has a U-shaped cross-section. The support frame has a middle main wall formed with an elongated groove, and two side walls extending rearwardly away from the main wall. The moving seat is connected slidably to guide rails disposed on the support frame, and has a middle plate that faces closely toward a rear surface of the main wall of the support frame, and two side plates that extend rearwardly similar to the side walls of the support frame. A massage unit includes a massage motor connected to the moving seat, a rotating shaft projecting forwardly through the elongated groove, and a head portion connected to the rotating shaft.
Abstract:
A walking assistance device configured to permit the independent movement of an individual via simulated weight reduction is described. The device is configured to partially suspend a portion of a user's weight via a suspension system, facilitating the movement of a user with experiencing difficulty walking without assistance. The suspension system of the device preferably employs at least one cable in communication with a pulley system, an electric lifting actuator, and a harness. The harness of the device is configured to affix to the legs and torso of the user, and connects to at least one cable of the pulley system via at least one hook. The lifting actuator engages the pulley system, enabling the user to control the percentage of weight lifted. A frame houses the suspension system of the device, and is configured to move laterally via wheels on the bottom of the frame of the device.
Abstract:
The present invention relates to devices and methods for exercising the lower limbs, in particular for exercising lower limbs. The devices are suitable for training the lower limbs of persons suffering from paraplegia or hemiplegia or musculoskeletal disorders in general. In some aspects, the present invention relates to powered articulated systems (ASs) and to the rehabilitation by aid of said ASs. The parallel or hybrid ASs of the invention are based on a parallel or hybrid, lambda-type framework and are controlled by a data processing unit. The ASs are preferably controlled by a closed-loop, real time control system.
Abstract:
Systems and methods for assistive devices for replacing or augmenting the limb of an individual, such devices comprising a joint and a powered system; the powered system having a first configuration in which the powered system rotates the joint by applying power to the joint, and a second configuration that allows for rotation of the joint without actuation of the powered system.

Abstract:
A joint actuation device for adding torque to a joint of a user includes an actuation system having an actuator and a spring. A lever is configured to couple to the user's leg and to the actuation system. The lever configured to rotate at a device joint with respect to the actuation system. A first sensor measures a position of the device joint. A second sensor measures deflection in a spring. The actuator is positioned based on the position of the device joint and deflection in the spring. The actuator is configured to deflect the spring to apply a torque the device joint. The device joint aligns with the user's joint to add a torque to the user's joint during a gait activity. The actuator disengages the spring during a non-gait activity. The lever is configured to disengage from the actuator when the device joint exceeds a predetermined angle.
Abstract:
A system includes a vibration unit that provides independent adjustability of vibration characteristics such as frequency and amplitude and may provide a first motor that rotates an eccentric and can adjust vibration frequency and a second motor that that may move the eccentric within the vibration unit in a manner that adjusts amplitude of the vibration.
Abstract:
A driving module and a motion assistance apparatus including the same may be provided. For example, the driving module including a driving source provided on one side of a user and configured to transmit power, a power transmitting rotary body configured to rotate by the power transmitted from the driving source, and a first decelerator configured to transmit power between the driving source and the power transmitting rotary body, the first decelerator having an input side rotary body configured to receive power from the driving source, and an output side rotary body configured to transmit power to the power transmitting rotary body may be provided.
