Embodiments of the present invention provide an oral device. According to one embodiment of the present invention, a mouthpiece suitable to detachably engage teeth of an upper jaw is provided. The mouthpiece comprises an adhesive layer configured to attach a hermetically sealed chamber to the mouthpiece. The hermitically sealed chamber fits within a concave space created by the mouthpiece. The hermitically sealed chamber comprises two layers and embedded between those two layers are a pressure sensor, a microphone, an optical sensor, a temperature sensor, a communications module, a storage enclosure, and a biosensor. Each of the pressure sensor, the microphone, the optical sensor, the temperature sensor, the communications module, the storage enclosure, and the biosensor are operably connected within the hermetically sealed chamber.

Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed.

A first value of an electrical stimulation parameter of an electrical stimulation therapy that resulted in a first physiological response for a patient is identified. The electrical stimulation therapy is delivered at least in part through a lead that is implanted inside the patient. Based on the first value, a limit of a second value of the electrical stimulation parameter that should result in a second physiological response for the patient is determined. An actual second value of the electrical stimulation parameter that actually resulted in the second physiological response for the patient is identified. Based on a comparison of the limit of the second value and the actual second value, an implantation of the lead is evaluated.

A kinesitherapy apparatus includes a measuring instrument, a pedaled rotational mechanism, a rotating electrical machine configured to apply an assist load, which is a regenerative load or a power running load, to the pedaled rotational mechanism, and a motion control device. The motion control device performs power running operation of the rotating electrical machine so that a minus assist load is generated in a warm-up period. In a ramp loading period following the warm-up period, the motion control device raises the assist load from the minus assist load, and calculates an anaerobic threshold based on time-series data of oxygen uptake and carbon dioxide emission that are obtained via the measuring instrument.

The present disclosure describes systems, devices, and methods for determining stability of a joint of a living subject. In one aspect, a force-measuring device for determining stability of a joint of a living subject is provided. In some examples, the force-measuring device includes a mitt frame configured to receive a hand of a user therein, one or more first force sensors, and one or more second force sensors. The mitt frame may include a palm portion configured to receive a palm of the user therein, and a finger portion configured to receive fingers of the user therein. The one or more first force sensors may be coupled to the palm portion and disposed on an exterior surface of the palm portion. The one or more second force sensors may be coupled to the finger portion and disposed on an exterior surface of the finger portion.

A system for quantification of exercise and physical therapy includes an anchoring module and an electronics module. The anchoring module is removably attached to an object (e.g., a flexible resistive band) or equipped with a clamping mechanism for removably securing the object. The anchoring module also includes an anchoring-module coupling fixture. At least one of the modules includes a sensor (e.g., a force sensor) configured to generate a signal representative of a user's performance during exercise or physical therapy; a processor configured to receive signals from the force sensor; a computer storage medium storing software code and in communication with the processor, wherein the software code includes instruction for processing the signals from the force sensor to quantify the performance; and at least one electronics-module coupling fixture configured to secure the electronics module to the anchoring module coupling fixture.

A wireless system comprising a first wireless device and a second wireless device. The first wireless device is configured to operate with less than 15 milliamperes of current. The second wireless device has an internal power source and is configured to transmit one or more radio frequency signals to the first wireless device. The first wireless device is configured to receive the one or more radio frequency signals from the second wireless device. The first wireless device is configured to harvest energy from the one or more radio frequency signals. The first wireless device is enabled for operation after a predetermined amount of energy is harvested from the one or more radio frequency signals. A communication handshake occurs between the first and second wireless devices to indicate that the first wireless device is in communication with the second wireless device. The first wireless device is configured to perform at least one task from harvested energy.

The invention relates to a method and a system for determining body's readiness to respond to physical exercise and for providing feedback to a user. In the method the user starts to perform an exercise, an earlier performance level is determined before starting a performance check having steps of: an instant performance level of the user is determined, the earlier performance level is compared to the instant performance level, a readiness index is determined according to the said comparison and optionally with background and/or training history of the user, a feedback is given according to the determined readiness index.

An intraoral multisensor device includes a mouthpiece, a plurality of sensors at least one of attached to or integrated with the mouthpiece, and a data communications unit configured to receive signals from the plurality of sensors. The mouthpiece has a form to permit stable arrangement at least partially within a person's mouth such that it can remain for hands-free sensing of a plurality of biological parameters. Also, an intraoral multisensor system includes an intraoral multisensor device and a data processing device adapted to communicate with the intraoral multisensor device.

Various systems are disclosed herein for detecting, monitoring, evaluating, and characterizing pain. They systems include a number of connected components, such as a provider device, a body-mapping system, a patient device, a user device, a referred pain device and/or a rectal probe device. Accordingly, the systems allow providers to track location-specific pain intensity for any number of patients over time in order to generate reports and determine treatment recommendations for such patients.
