It is disclosed an apparatus (100) for tactile stimulation of C-Tactile afferents comprising a casing (10) configured to be positioned onto a user's skin and at least one tactile stimulation element (21) carried by the casing (10) and operated by a motor (30) at a controlled velocity for generating at least one tactile stimulation. The apparatus (100) further comprises an electronic control unit (40) and at least one pressure sensor (50) in electrical communication with the electronic control unit (40) to control the pressure force exerted by the tactile stimulation element (21) onto the user's skin by adjusting the position of the tactile stimulation element (21) with respect to the user's skin, based on a feedback signal transmitted by said at least one pressure sensor (50). A method of generating at least one tactile stimulation of C-Tactile afferents carried out by using the aforesaid apparatus (100) is also disclosed.

A system for obtaining and analyzing data for overall joint motion from a plurality of joints of a subject experiencing a movement disorder involves a plurality of kinematic sensors configured to be placed on a body of a subject proximal a plurality of joints. The kinematic sensors are selected to measure overall joint motion with sufficient degrees of freedom for individual joints so that data collected by the sensors can be deconstructed into multiple degrees of freedom for individual joints and analyzed to provide amplitude of the movements caused by the movement disorder and/or relative contributions from and/or directional bias for each muscle group that may be implicated in the movement of each joint. The system permits determining a treatment regimen based on the amplitude of the movements and/or the relative contribution and/or directional bias of each muscle group to the movements caused by the movement disorder.

Described herein are systems and methods of guiding a user to achieve musculoskeletal counterpulsation. A method may include receiving a cardiovascular cycle signal from a first sensor; determining a heart rate of the user based on the cardiovascular cycle signal; receiving a rhythmic musculoskeletal activity timing signal from a second sensor; determining an actual musculoskeletal activity cycle (MSKC) to cardiovascular cycle (CC) timing relationship; comparing the actual MSKC to CC timing relationship to a target MSKC to CC timing relationship; providing a recurrent prompt to the user as a timing indication for performance of a rhythmic musculoskeletal activity to guide the user to achieve a musculoskeletal activity cycle rate (MSKR) that approaches the target MSKC to CC timing relationship; and altering a feature of the recurrent prompt based on a determined alignment between the actual MSKC to CC timing relationship and the target MSKC to CC timing relationship.

An exoskeleton device for rehabilitation of distal joints of an upper limb of a patient is described. The exoskeleton device includes a multi-bar linkage and a first platform to support fingers of the patient. The exoskeleton device includes a second platform to support a palm of the patient. The first platform and the second platform are coupled to the multi-bar linkage. The exoskeleton device also includes a transmission unit to drive the multi-bar linkage to move the first platform and the second platform to provide flexion and extension of the distal joints of the upper limb of the patient. In addition, the exoskeleton device includes an armrest and a fastening mechanism to fasten a forearm of the patient.

A device and method are provided for therapy and treatment of biological tissue such as muscle, tendon, and ligament tissue, by use of a device and method in which therapeutic vibrational frequency resonance patterns are transmitted to tissues of a patient. The resonance frequencies originate from many resonance domains, including vitamins, minerals, herbs, amino acids, and fatty acids. Each domain includes therapeutic frequency resonance patterns. These resonance patterns may be passively excited and transmitted to a patient to enhance tissue function, to decrease the normal rehabilitation time of damaged tissue, and provide therapeutic benefits for muscle tissue dysfunction. Therapeutic frequency resonance patterns may also be actively excited by a delivery mechanism that uses electromagnetic or mechanical waves to interact with the device. The actively excited device transmits the therapeutic frequency resonance patterns to the patients for similar enhancements and therapeutic benefits.

A lower-leg exoskeleton that includes an actuator configured to be worn about a portion a leg of a user that is below the knee of the user; and a foot structure coupled to a first actuator end of the actuator, the foot structure configured to surround a portion of the foot of the user. The foot structure includes one or more sidewalls configured to extend around the foot of the user and including one or more sidewall attachment points for connecting to a base portion, and a base portion configured to reside at a base of the foot of the user and including one or more base attachment points coupling with the one or more sidewall attachment points.

Systems and methods for analysis of symmetry between sides of a body. A wearable device includes a body mounting portion structured and arranged to, in use, be mounted to one or more parts of a body of a patient on one side of the body. The wearable device includes at least one sensor configured to output a signal indicative of at least one physiological parameter from a side of the body to which the wearable device is mounted. At least one processor is configured to receive at least one physiological parameter from the wearable device while mounted to a first side of the body, and at least one physiological parameter from the wearable device while mounted to a second side of the body. An indicator of symmetry between the first side and the second side of the body is determined based at least in part on the at least one physiological parameter from the first side of the body and the at least one physiological parameter from the second side of the body.

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.

A walking assistance method may include measuring a current gait motion of a user, defining a state variable based on the current gait motion, setting a delay that is a feedback element for the state variable, and generating a torque profile based on the state variable and the delay.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.
