Methods, systems and devices for reducing anxiety, including increasing relaxation and/or calm. In some variations these methods may include reducing anxiety, increase relaxation and/or calm by non-invasive temperature regulation of the frontal cortex prior to and/or during sleep. The subject may have an anxiety disorder, or may not have a diagnosed anxiety disorder.

This document describes systems and methods for controlling an exoskeleton. The system receives a measurement of a first torque applied to a rotational joint coupling a first component to a second component, the first torque being applied by a motor via a cable. The system determines, based on the measurement of the first torque, a first portion of a second torque to apply to the rotational joint. The system determines, based on the measurement of the first torque, a second portion of the second torque to apply to the rotational joint. The system determines a value of the second torque to apply to the rotational joint based on the first portion and the second portion. The system controls the motor for applying the second torque to the rotational joint via the cable.

A method and device for outputting a torque of a walking assistance device is provided. The method and device may determine a degree of progress in a gait cycle based on data received through wireless communication, calculate a torque corresponding to the determined degree of progress, and output the torque to a driver of the walking assistance device. However, when the data received through wireless communication is not updated data, the method and device may determine reference data based on a reference pattern, and update the data using the determined reference data.

A lower-leg exoskeleton including an inflatable actuator that is configured to be worn over a front portion of a foot of a user; a rigid foot structure coupled to the inflatable actuator that is configured to surround a portion of a foot of the user; and a rigid shin structure coupled to the inflatable actuator and configured to engage the shin of the user. When worn by a user, the lower-leg exoskeleton can receive and transmit an actuator load generated by the inflatable actuator to a load contact point defined by the rigid foot structure which is forward of the heel of a user. Inflation of the inflatable actuator can generate a moment about the ankle of a user to cause flexion of the foot of the user.

Generator systems and methods are provided for generating a neuromuscular-to-motion decoder from a healthy limb. The generator system is configured to receive neuromuscular signals from neuromuscular sensors associated to predefined muscle/nerve locations of at least one pair of agonist and antagonist muscles/nerves of the healthy limb, obtained during performance by the person of a predefined exercise (defined by predefined exercise data) with the healthy limb; to receive motion signals from motion sensors associated to predefined positions of the healthy limb, during performance by the person of the predefined exercise with the healthy limb; and to generate the neuromuscular-to-motion decoder by mapping the neuromuscular signals to the motion signals over time using a mapping method. Rehabilitation systems are also provided for rehabilitating a paretic limb by using a neuromuscular-to-motion decoder produced by a generator system.

Systems and methods for digital reflex quantization and signature analysis. Movement of a stimulating device invoking a reflex response in an organism is captured as stimuli data. Electromyographic (EMG) of the reflex response is captured as EMG data. Movement resulting from the reflex response of a limb/appendage of the organism is captured as motion data. One or more of the stimuli data, the EMG data, and the motion data are analyzed to determine one or both of a motion signature and an EMG signature defining quantitative evaluation of the reflex response.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

A system for relieving pain of a user includes an electromechanical transducer configured to generate generate tactile sound waves (vibrations) with a frequency between 5 Hz and 200 Hz, a holder configured to keep the transducer in a fixed position adjacent to the mesenterial and internal organs' Pacinian corpuscles located in the abdominal cavity of the user, and a controller configured to control the amplitude and frequency of the transducer.

Wearable assistance devices and methods of operating the same are provided. A wearable assistance device includes an upper-body interface with a front side and a rear side and a lower-body interface with a front side and a rear side. The assistance device also includes one or more elastic members, each of the elastic members mechanically coupling the upper-body interface to the lower-body interface and extending from the rear side of the upper-body interface to the rear side of the lower-body interface and along a back of the user so as to provide an assistive force parallel to the back of the user. Further, the assistance device also includes a clutch mechanism associated with each one of the elastic members, the clutch mechanism configured for selectively adjusting the assistive force provided by the one of the elastic members.
