The method comprises: the reception of a plurality of electromyographic signals (S.sub.EMG) representative of a detected muscle activity of a plurality of selected muscles of the subject, as well as a plurality of brain signals (S.sub.EEG) acquired by means of an electroencephalogram and representative of a cortical activity of the subject during said muscle activity; the analysis and processing of the electromyographic signals (S.sub.EMG) in order to extract a muscle activity pattern, MAP, and generate an indicator of normality/abnormality of the detected muscle activity pattern; the analysis and processing of the brain signals (S.sub.EEG) in order to generate one or more cortical response indicators of the subject upon occurrence of said detected muscle activity (I.sub.EGg; LF(k)); and a classification step, wherein at least one indicator (MA(k)) of normality/abnormality of the MAP and one or more of said cortical response indicators are correlated to generate a signal (Aout) indicating an imminent loss of balance.

Assessment of cognitive function affected by brain injuries is achieved. This included, but is not limited to, assessment of cognitive function affected by brain injuries, for example injuries sustained during sporting activities. A virtual reality system is used to apply controlled cognitive loading to the subject, via a series of distinct test types which in combination apply an increasing cognitive load over time. Results are optionally assessed in conjunction with data from an instrumented mouthguard and/or Finite Element Analysis (FEA) model.

The present invention relates to a physical performance assessment method including the steps of: collecting a patient's motion acceleration signals for the patient's motion analysis measured from a motion acceleration sensor attached to the patient's head through a motion measurement module; and deriving a plurality of motion parameters based on the collected motion acceleration signals through a motion analysis module.

Method and system of training a machine learning neural network (MLNN) monitoring anatomical dynamics of a subject in motion. The method comprises receiving, in a first input layer of the MLNN, from a millimeter wave (mmWave) radar sensing device, mmWave radar point cloud data representing a first gait characteristic; receiving, in a second layer of the MLNN, from the mmWave radar sensing device, mmWave radar point cloud data representing a second gait characteristic; the first and the at least a second input layers being interconnected with an output layer via an intermediate layer having an initial matrix of weights; training a MLNN classifier based on a supervised classification establishing correlation between a degenerative condition of the subject at the output layer and the point cloud data; and adjusting the initial matrix of weights by backpropagation to increase correlation between the degenerative condition and the sets of point cloud data.

A balance prosthesis device for an individual including a sensor module configured to obtain a sensor signal indicative of a balance or equilibrium state of the individual, a processing module configured to determine at least one neurostimulation signal based at least in part on the obtained sensor signal, and a transmitter module configured to transmit the determined neurostimulation signal to a neurostimulation device of the individual. The neurostimulation signal is configured to elicit an artificial sensation in a specific sensory cortex area of the individual via directly stimulating afferent sensory axons of the central or peripheral nervous system of the individual targeting sensory neurons of the sensory cortex area not directly associated with vestibulocortical pathways of the individual. The elicited artificial sensation provides a balance indication to the individual in order to support, mimic, substitute or enhance the natural sense of balance of the individual.

Bilateral vestibular loss is a chronic condition of which the causes can be ototoxic, infectious, traumatic, autoimmune or congenital. An object of the invention is to improve the effectiveness of a vibrotactile feedback arrangement. The current invention provides a vibrotactile feedback arrangement for use arranged to a human body, comprising: a sensor arranged for sensing a current attitude of the human body relative to the environment; tactile actuators arranged for allowing the human body to perceive an attitude deviation; an elongated carrier for holding the tactile actuators and the sensor in tactile communication with the human body and for holding the tactile actuators and the sensor substantially fixed relative to the human body; and a processing unit configured for: receiving the current attitude from the sensor; determining the attitude deviation based on comparing a desired attitude of the human body with the current attitude; and transmitting an actuation signal to one or more of the tactile actuators based on the attitude deviation; wherein the tactile actuators are arranged to the carrier such that, when the carrier is used, the tactile actuators are arranged substantially in a reference plane; wherein the reference plane is functionally perpendicular to a central axis of a torso of the human body and the reference plane intersects the torso to define a circumference, wherein the tactile actuators are arranged to the circumference; and wherein the carrier comprises stretchable material such that the relative distance between the tactile actuators and/or between the tactile actuators and the sensor is maintained independent of the length of the circumference.
