A method includes disposing a plurality of actuators about a subject, each actuator being configured to generate a respective vibration signal, each vibration signal applying a normal force to the subject, and controlling the plurality of actuators such that the respective vibration signal of each actuator of the plurality has a respective vibration characteristic. Each actuator is oriented such that the respective vibration signal propagates along a longitudinal axis of the subject for stimulation of the subject remote from the plurality of actuators.

Disclosed herein is a device for measuring knee adduction moment or knee abduction moment, which has: (a) a thigh portion, comprising a tissue interface, having two or more force sensors, operatively coupled to a data processing unit, configured to be positioned generally on the lateral and medial sides of the leg, when in use; (b) a shank portion, comprising a tissue interface, having two or more force sensors, operatively coupled to a data processing unit, configured to be positioned generally on the lateral and medial sides of the leg, when in use; (c) a knee assembly, configured to rotate with the knee, rotatably coupling the thigh portion to the shank portion; and (d) at least two attachment loci, wherein the knee assembly is attached to the thigh portion at a first attachment locus, and wherein the knee assembly is attached to the shank portion at a second attachment locus.

Embodiments disclosed herein are directed to personal therapy and exercise systems as well as to methods related thereto. For example, a personal therapy system can be a modular system that can include multiple therapy gear modules.

A cardiopulmonary resuscitation (CPR) device for performing automatic defibrillation and chest compressions on a patient and method for using same. The CPR device having a balloon configured to inflate/deflate, a belt configured to securely strap around a chest of a patient, a pair of electrode pads configured to deliver shock energy from a shock source, and, optionally, a pulse oximeter sensor. The CPR device is in electrical communication with a CPR defibrillator/ECG computer system that is configured to control the CPR device.

A system for assisting with a chest compression treatment being administered to a patient. In one aspect, the system for assisting with chest compression treatment includes at least one sensor configured to measure blood flow data, one or more processors, in communication with the at least one sensor, and an output device configured to provide the output indication to the rescuer. The one or more processors are configured to perform operations including receiving the blood flow data from the at least one sensor, based on the blood flow data, generating arterial blood flow data and venous blood flow data, providing an estimation of chest compression effectiveness based on the arterial blood flow data and the venous blood flow data, the estimation being based on at least one peak comparison of arterial blood flow and venous blood flow, and generating an output indication of the estimation of chest compression effectiveness.

A wearable technology, referred to herein as biometric bodysuit, which integrates biometric sensors, electromagnetic stimulation, and wireless control modules having the capacity to communicate with an interactive user interface. The body is comprised of at least one segment covering at least a portion of a body of a wearer. The segments include an arm covering, a leg covering, a torso covering, footwear, handwear, headwear, and any combination thereof. The segments include a series of control modules that relay real-time biometric data to a main control module, wherein the data is then relayed to a server and a user interface. The user interface permits wearers of the bodysuit and healthcare professionals to adjust the functionality of the bodysuit in accordance to what is the necessary therapy required by the wearer.

A concentration measurement apparatus measures a temporal relative change amount (cHb, O.sub.2Hb) of either or both of total hemoglobin concentration and oxygenated hemoglobin concentration in the head that vary due to repetition of chest compression, and includes a light incidence section making measurement light incident on the head, a light detection section detecting the measurement light propagated through the interior of the head and generating a detection signal in accordance with the intensity of the measurement light, and a CPU determining, based on the detection signal, the relative change amount (cHb, O.sub.2Hb) and performing a filtering process of removing frequency components less than a predetermined frequency from frequency components contained in the relative change amount (cHb, O.sub.2Hb).

A system for facilitating cardiopulmonary resuscitation (CPR) by a CPR performer on a patient includes first, second, and third sensors configured to be positioned at least partially between a hand of the CPR performer and a chest of the patient. The first sensor is configured to measure a depth of compressions provided by the CPR performer on the patient. The second sensor is configured to measure a rate of the compressions. The third sensor is configured to measure a recoil of the compressions. The system also includes a computing system configured to receive data from the first, second, and third sensors. The computing system is also configured to compare the received data to stored data in a library that corresponds to the received data. The computing system is also configured to generate one or more outputs in response to the comparison.

An example neck massaging system includes a housing. The housing is configured to fit around a neck of a wearer. As such, the housing includes an interior region defining an opening configured to receive the neck. The housing also includes a top region and a bottom region opposite the top region. The neck massaging system further includes at least one massager attached to the housing. The massager is positioned on the housing to be adjacent to the interior region which allows the massager to contact the neck. In an example, the massager is positioned on the housing such that the massager contacts the internal jugular vein. The neck massaging system also include at least one actuator operably coupled to the massager. The actuator is configured to move a portion of the massager adjacent to the neck in a direction that generally extends from the top region to the bottom region.
