A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.

A nerve stimulator is provided, and in particular a non-invasive nerve stimulator for peripheral nerves, such as the ulnar and/or median nerves. The stimulator may be fitted proximate the left and/or right arm, wrist or hand of a user, to stimulate the median and/or ulnar nerves using electricity, light, sound, magnetic field, vibration or pressure, or any combination of these stimuli. The apparatus takes the form of a standalone band or clasp, or forms part of a fitness tracker band, watch or smartwatch. The nerve stimulator comprises a stimulus generator, to generate any or a combination of the stimuli mentioned above, an applicator to apply the generated stimulus to the arm, wrist or hand of the user, and a controller to control the operation of the stimulus generator and the applicator. In some cases, for stimuli such as light, sound, magnetic field, vibration or pressure, the generator and applicator may be combined into a single component.

Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.

Systems, and methods relate to a medical device receiving a treatment parameter operating point within a first operating region defined by a first set of operating points for which automatic incremental adjustment of a parameter in the current operation is permitted. In an illustrative example, incremental adjustment may use artificial intelligence based on patient feedback and sensor measurement of outcomes. Some exemplary devices may receive a request to alter the current treatment parameter operating point to a second treatment parameter operating point outside the first operating region and in a second operating region in a known safe operation zone, bounded by a known unsafe zone unavailable to the user. In the second operating region, some examples may restrict the step size of incremental adjustments requested by the user. Data may be collected for cloud-based analysis, for example, to facilitate discovery of more effective treatment protocols.

Embodiments of the present disclosure relate generally to the use of spectral sensors during a cardiac arrest event. More specifically, the present disclosure relates to the use of spectral sensors for measuring changes in pH and muscle oxygen saturation to estimate subject down time and evaluating the effectiveness of the clinical treatment administered during a cardiac arrest event. Given the narrow window of time in which emergency treatment must be administered, as well as the lack of information concerning the subject's condition, there is a need for a fast and accurate method of estimating the onset of the cardiac arrest emergency and evaluating the effectiveness of the emergency treatment being administered.

An embodiment of a system for treating sleep apnea includes a collar, a pump, a motor, a sensor, and a controller. The collar is configured to maintain an airway of a subject open while the subject is sleeping by applying, to a throat of the subject, a negative pressure having a magnitude, and the pump is configured to generate the negative pressure. The motor is configured to drive the pump, and the sensor is configured to generate a sense signal that is related to a degree to which the airway is open. And the controller is configured to vary the magnitude of the negative pressure in response to the sense signal. For example, one or more of the pump, motor, sensor, and controller can be secured to the collar such that the system is self-contained, i.e., the entire sleep-apnea system can be worn by the subject.

A system for improving cardiac output of a patient suffering from pulseless electrical activity or shock and yet displays myocardial wall motion including: a sensor to detect myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase, a device to prompt the application of or apply a compressive force repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion.

A method is provided for a novel application of trigger point dry needling. A target tissue is identified based on the observation of a series of movement patterns performed by the patient. Once identified, a needle movement protocol is used to insert a needle into the target tissue to a myofascial trigger point during one or more movement patterns. The needle protocol is adjusted until a local twitch response is induced.

A rehabilitation feedback system is used during rehabilitation of one or more body appendages of a user. The system includes four finger tracking elements and a thumb tracking element supported for movement relative to one another so as to allow a user to performs a gripping motion when the elements are coupled to the fingers and thumb of a user. A biasing member provides a resistance force acting to urge each tracking element towards a starting position thereof. A visual barrier is adapted to hide the hand of the user at a first side of the visual barrier from direct visual sight by the user at a second side of the visual barrier. A sensor at the first side of the visual barrier detects movements of the tracking elements and communicates with an indicator element detectable by the user from a second side of the visual barrier.

The application presents a multi-posture lower limb rehabilitation robot, which includes a robot base and a training bed. The training bed comprises two sets of leg mechanisms, a seat, a seat width adjustment mechanism, a mechanism for adjusting the gravity center of human body, a back cushion, a weight support system and a mechanism for adjusting the back cushion angle. The robot base comprises a mechanism for adjusting the bed angle. The mechanisms for adjusting the angles of bed and back cushion can be used together to provide paralysis patients with multiple training modes of lying, sitting, and standing postures. Each leg mechanism comprises hip, knee, and ankle joints, which are driven by electric motors; angle and force sensors are installed on each joint, and can be used to identify patients' motion intention to provide patients with active and assistant training. The mechanism for adjusting the gravity center of human body, the leg mechanisms, and the weight support system can be used together to implement human natural walking gait to improve the training effect.
