Embodiments herein relate to devices and related systems and methods for motion sickness prevention and mitigation. In an embodiment, a method of preventing or mitigating motion sickness in a subject is included, the method tracking motion of the subject using a first motion sensor; estimating a vestibular system input based on tracked motion of the subject; tracking head position of the subject using the first motion sensor; estimating a visual system input based on tracked head position of the subject; estimating consistency between the vestibular system input and the visual system input; and initiating a responsive measure if the estimated consistency crosses a threshold value. Other embodiments are also included herein.

Disclosed are various embodiments of a virtual reality Berg balance scale. A patient can perform a Berg balance test using a virtual reality system. The system can include at least one wearable sensor worn by a patient, and at least one environmental monitor directed towards the patient. A computing device can acquire movement data from the wearable sensor. The computing device can acquire environment data from the environmental monitor. An application on the computing device can then calculate one or more balance scores based at least in part on the movement data and the environment data.

To provide a motor function evaluation device and a motor function evaluation method capable of evaluating a motor function of a subject comprehensively and easily. A motor function evaluation device 1 of the present invention includes a measurement base 11, a load measurement unit 14 that measures load change over time of the subject applied to the measurement base 11, and an arithmetic unit 24 that determines a balance ability indicator of the subject determined by the load change over time measured by the load measurement unit 14. The arithmetic unit 24 determines the balance ability indicator from a time interval from when the subject stands up and the load applied to the load measurement unit 14 is maximized until when the load variation is stabilized.

Described is a system for system for gait intervention and fall prevention. The system is incorporated into a body suit having a plurality of distributed sensors and a vestibulo-muscular biostim array. The sensors are operable for providing biosensor data to the analytics module, while the vestibulo-muscular biostim array includes a plurality of distributed effectors. The analytics module is connected with the body suit and sensors and is operable for receiving biosensor data and analyzing a particular user's gait and predicting falls. Finally, a closed-loop biostim control module is included for activating the vestibulo-muscular biostim array to compensate for a risk of a predicted fall.

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.

The methods, systems, and computer program products described herein enable the amount of information that can be acquired during a defined period of vestibular testing to be significantly increased while also significantly reducing the time required to collect data during such vestibular testing. These objects are achieved by intelligent data collection methods and systems configured to adaptively control a motion platform in a way that increases the amount of information gleaned from each data collection event and to achieve synergies based on the different types of, and the order of, data analysis and calibration methods used.

Disclosed herein is a system that uses an eye tracker for diagnosing and facilitating rehabilitation therapy of a patient suffering from disability. The system creates a human machine interface (HMI) that integrates various low cost biosensors and artificial sensors for conducting rehabilitation therapy. The system combines spinal and supra-spinal feedback of the patient with the operant conditioning to facilitate visuomotor balance therapy (VBT), thereby reducing fall risk in disability survivors. The operant conditioning setup for shaping of visuomotor learning to bring about new behavior or to modify a certain aspect of an existing behavior is used for rehabilitation therapy that includes a behaviour response apparatus, a reward delivery module, a stimulus delivery system, and a behaviour control system. The system can also be extended to the patient's home for providing telerehabilitation therapy.

The present invention relates to an apparatus for measuring the balance ability; postural deviation, reflex and fall risk assessment of a human subject. In particular, the present invention comprises of an elastic support mounted platform with dynamic response to external motion stimuli, a IMU and data analysis software processing device. The dynamic response from the platform also simulates realistic experience in moving over rough terrain with different topography.

A system and method for using a virtual reality or an augmented reality environment for the measurement and/or improvement of human vestibulo-ocular performance can be implemented by combining a video camera based eye orientation sensor, a head orientation sensor, a display, and an electronic circuit that connects the eye sensor, head sensor, and display. The system and method can be operated in the range of frequencies between 0.01 Hertz and 15 Hertz. The system and method can use a Fourier transform to compute a gain and a phase. The system and method can be used for measuring vestibulo-ocular reflex, dynamic visual acuity, dynamic visual stability, kinetic visual acuity, retinal image stability, or foveal fixation stability in a non-clinical setting. The system and method can be completely portable, head-worn, and self-contained.

Balance measurement systems and methods thereof include at least one measurement device or indicator and an unstable or dynamic device or surface or other balance device. In example forms, the at least one measurement device is generally removably mounted to a portion of the body of a user (and/or to a portion of the balance device) such that the movements and body behavior of a user (and/or the balance device) can be measured as the user attempts to balance on the balance device. According to one example form, the unstable device includes a suspended rope or slackline. According to other example forms, the balance device includes a generally unstable platform.
