A method and apparatus for testing balance of a subject is provided. The apparatus includes a plurality of modules detachably coupled together to form a walkway. Each module includes an obstacle. The obstacle of one of the modules is a movable obstacle configured to move from a first position to a second position. The obstacle of one of the modules is a fixed obstacle in a fixed position. A system is also provided that includes the apparatus of the first set of embodiments. The system also includes a sensor configured to measure a value of a parameter indicating a characteristic of motion of a subject over the walkway. A method is also provided that includes detachably coupling the plurality of modules together to form the walkway. The method further includes measuring the parameter value indicating the response of the subject to each obstacle of each module along the walkway.

A balance detection and correction system includes at least one sensor positioned in an ear of a user, a processor, and a memory having instructions stored thereon that, when executed by the processor, causes the processor to perform operations including continuously tracking a position of the user’s head based on first data obtained from the first sensor, comparing the position of the user’s head to second data obtained from a second sensor positioned on the user’s body to detect an imbalance in the user’s posture or movements, and initiating a response action responsive to the detection of an imbalance.

Systems, devices and methods are provided for determining injury risk and athletic readiness based on user movement data, including movement variability data. Generally, a sensor device, such as a force plate, is provided for sensing certain characteristics of a user movement. A computing device coupled to the sensor device can be configured to receive sensor data indicative of the characteristics of the user movement, process and extract information from the sensor data, and transmit the processed sensor data to a server system. The remote server system can be configured to store, aggregate and update the processed sensor data in a database, and can also generate one or more normalized scores correlating to the user movement. The normalized scores can indicate to a user a susceptibility to injury and/or a readiness towards return to normal activity.

A device for motion sickness reduction. The device operates by providing haptic feedback using transducers that convert electrical signals to a tactile sensation such as pressure, vibration, electrical stimulation, temperature, or airflow. The transducers are located at different locations on the body of a user, and actively change their operation to indicate a direction of motion or rotation to the user through haptic (tactile) feedback. This tactile feedback can be used to reduce motion sickness. In an embodiment, the feedback is improved by deducting motion associated with the user's visual frame of reference from motion associated with the user's vestibular frame of reference.

A wearable, flexible, bio-sensing housing with physical feedback, with software running on a user's wirelessly connected smart device. The housing has embedded at least one of pressure, movement, temperature, velocity, and acceleration sensors, and at least one of a haptic, vibrational, audio, visual, kinesthetic, tactile, olfactory, thermal, vestibular, and somatosensory feedback mechanisms. The feedback being triggered by measurements from the sensors and predetermined parameters, as compared by the smart device's software and/or a connected server. With real-time measurements and real-time feedback directly to the user's body, the user can perform real-time adjustment of his activity to obtain optimal performance and/or health.

This disclosure provides methods for diagnosing a cognitive disorder including performing a tactile perception test on a subject, measuring the subject's tactile perception test performance with a microelectromechanical sensor, and performing a cognitive disorder diagnosis on the subject. The tactile perception test may include distinguishing between various shaped and sized objects and selecting a predetermined one. The tactile perception test may include a two-point discrimination test. The tactile perception test may include testing lower extremity coordination. The tactile perception test may include testing upper extremity coordination. The cognitive disorder may include dementia, Alzheimer's, brain trauma, or concussion. The microelectromechanical sensor may include an accelerometer or gyroscope.

A method and system for monitoring a user's intoxication including receiving a set of signals, derived from a set of samples collected from the user at a set of time points; providing a sobriety task to the user proximal to a time point of the set of time points; generating a performance dataset characterizing performance of the sobriety task by the user; receiving a supplementary dataset characterizing a demographic profile of the user and/or a physiological state of the user; determining a set of values of an intoxication metric, derived from the set of signals; generating a predicted temporal profile of the intoxication metric for the user based upon the set of values, the set of time points, and the supplementary dataset; generating an analysis of the user's sobriety based upon the performance dataset and the predicted temporal profile; and providing a notification to the user based upon the analysis.

A system for transdermal alcohol sensing to be worn near a skin surface of a user, including: an alcohol sensor; a microporous membrane; a housing coupled to the alcohol sensor and the membrane, defining a volume between the alcohol sensor and a first membrane side, and fluidly isolating the volume from a second membrane side opposing the first membrane side; an electronics subsystem electrically coupled to the alcohol sensor, operable to power and receive signals from the alcohol sensor; and a fastener operable to position the second membrane side proximal the skin surface.

The systems, methods, apparatuses, and articles disclosed herein provide a new approach to treatment symptoms, such as proprioceptive dysfunction and vestibular disorders, which may be caused by certain types of human ailments. According to the present disclosure, a wearable article may include one or more limb sections and a resilient member may be provided along a length of each of the one or more limb sections and configured to generate a resistance force. Adjustments to the resistance force provided by the resilient member(s) may be adjusted using cord locks. As a user wearing the wearable article moves, the resistance force is applied to the user's limbs. Strain gauges may be provided to measure the resistance force(s), which enables verification that the resilient members are sized and configured to provide an appropriate amount of resistance force to a user and may improve programs and regimens designed to treat such ailments.
