The FES system includes an FES stimulator that is embedded within the component, and a plurality of FES jacks that are electrically connected to the FES stimulator and are located on the component. The FES jacks are configured to receive a plurality of FES electrodes, and an electrical stimulation output from the FES stimulator is conducted through the FES jacks to the FES electrodes. In a wireless embodiment, the FES stimulator is configured to wirelessly transmit a control signal for applying an electrical stimulation output to the plurality of FES electrodes, and the FES jacks are eliminated. The FES stimulator may be embedded within a back portion of the hip component of an exoskeleton device, and in the wired embodiment the FES jacks are located on wing portions of the hip component.
Gait disorder support apparatus and gait disorder support method
A gait disorder support apparatus and gait disorder support method capable of detecting an onset sign of a gait disorder associated with motor symptoms in advance and performing motion assist are proposed. The onset sign of the gait disorder associated with the motor symptoms of a wearer is detected based on the correlation between a gait cycle and a reduction ratio of the gait cycle as compared to immediately preceding gait; and when the onset sign of the gait disorder is detected, a drive unit is controlled so that the drive unit applies assist power to a knee joint of the wearer; and on the other hand, when the onset sign of the gait disorder is not detected, the drive unit is controlled so that driving torque by the drive unit does not hinder the wearer's gait motion.
Soft exosuit for assistance with human motion
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.
SYSTEMS FOR CLOSED-LOOP ULTRASOUND-IMAGING BASED CONTROL AND RELATED METHODS
Systems and methods for closed-loop ultrasound imaging-based control are described herein. An example system includes an ultrasound transducer, and a controller operably coupled to the ultrasound transducer. The controller includes a processor and memory, the memory having computer-executable instructions stored thereon. The controller is configured to receive an ultrasound imaging signal associated with a subject's muscular activity from the ultrasound transducer; process the ultrasound imaging signal to obtain a feedback signal; and control a device interfacing with the subject based on the feedback signal.
Ankle-less walking assistant apparatus and method for controlling the same
An ankle-less walking assistant apparatus includes: a body supporting the back of a wearer; left and right hip joint-drivers extending from both sides of the body; left and right thigh links having first ends connected to the left and right hip joint-drivers, respectively; left and right knee-drivers connected to second ends of the left and right thigh links, respectively; left and right calf links having first ends connected to the left and right knee-drivers, respectively; and ground-contact feet fixed to second ends of the left and right calf links, respectively.

The FES system includes an FES stimulator that is embedded within the component, and a plurality of FES jacks that are electrically connected to the FES stimulator and are located on the component. The FES jacks are configured to receive a plurality of FES electrodes, and an electrical stimulation output from the FES stimulator is conducted through the FES jacks to the FES electrodes. In a wireless embodiment, the FES stimulator is configured to wirelessly transmit a control signal for applying an electrical stimulation output to the plurality of FES electrodes, and the FES jacks are eliminated. The FES stimulator may be embedded within a back portion of the hip component of an exoskeleton device, and in the wired embodiment the FES jacks are located on wing portions of the hip component.
WALKING TRAINING SYSTEM, CONTROL METHOD THEREOF, AND CONTROL PROGRAM
The walking training device includes: a robot leg attached to one leg of a trainee; a treadmill; a load distribution sensor that detects a distribution of a load received from a sole of the trainee; and a walking state distinguishing unit that determines whether the one leg is in a swinging leg state; a control unit that performs a predetermined bending-extending control for the swinging leg state of the one leg by the robot leg when the one leg is in the swinging leg state; a measuring unit that measures a clearance between the one leg in the swinging leg state and the treadmill. The control unit changes control content of the predetermined bending-extending control so that the one leg does not contact the belt of the treadmill during extending control of the one leg, when the clearance is less than a specified value.
MOTION ASSIST DEVICE
This motion assist device 100 assists with flexing and extending of fingers F1, F2 of a user, the motion assist device 100 comprising: at least one arm 10; at least one connection member 20 configured so as to be capable of connecting the at least on arm 10 to each of the fingers F1, F2; an arm support mechanism 30 that turnably supports the at least one arm 10, the arm support mechanism 30 being configured so as to be mountable on the back Hb of the hand H of the user; an arm drive means 40 that causes the at least one arm 10 to turn; and a stopper 50 that extends from the arm support mechanism 30, the stopper 50 being configured so as to restrict movement of the proximal phalanges of the fingers of the user by being in contact with the proximal phalanges. The at least one arm 10 is configured so as to turn while the distance Dr between the at least one connection member 20 and the turning center Cr of the at least one arm 10 is kept fixed.
DYNAMIC REACTIVE SYSTEM AND METHOD TO SUPPORT AND CHANGE SITTING POSTURES
There is provided a dynamic and proactive system for supporting sitting while detecting and changing sitting postures of a user and method of operation thereof.
