A method and system for determining postural balance of the person is provided. The disclosure provides a single limb stance body balance analysis system which will aid medical practitioners to analyze crucial factor for fall risk minimization, injury prevention, fitness and rehabilitation. Skeleton data was captured using Kinect. Two parameters vibration-jitter and force per unit mass (FPUM) are derived for each body part to assess postural stability during SLS. Further, the vibration and force imposed on each joint a first balance score was quantified. A first balance score and a second balance are also calculated by combining vibration index and SLS duration to indicate the postural balance of the person. The vibration index is computed from the vibration profile associated different body segments.

Systems and methods for clinical assessment of balance may include a tilting balance platform further including: an upper platform, a lower platform, and an array of force transducers sandwiched between the upper platform and the lower platform. The systems may also include: a toroidal bladder supporting the lower platform; an air pressure sensor and a control valve connected to the toroidal bladder; an inclinometer that measures tilt information of the balance platform; and a computer that receives a control signal to activate one of: the array of force transducers and the inclinometer. If the array of force transducers is activated, then a clinical test is performed to measure changes to a subject's Center of Pressure on a stabilized balance platform, and if the inclinometer is activated, then another clinical test is performed to measure the tilt information caused by a subject's movements on a de-stabilized balance platform.

Disclosed herein are apparatus and methods for delivering bone conduction stimuli for measuring the gravitation receptor functions of the inner ear. In some embodiments, a system may include (i) an impactor operatively linked to a guide disposed within a housing and (ii) an electrically driven actuator enclosed within the housing.

Systems and methods are disclosed that record quantifiable data for physical exams that assess neurological function. A system includes four main components. First, it employs a flexible and customizable procedure administration and documentation system developed and deployed on a mobile platform to aid in the identification, administration, configuration, and instruction of a suite of procedures for assessing different aspects of vestibular health. Second, it leverages commercial off-the-shelf (COTS) hardware with integrated sensor technology to allow non-vestibular experts to conduct assessment procedures by imposing constraints that ensure accurate and safe administration of VF assessment procedures. Next, it utilizes a gaming engine to both capture patient responses and to enable the accurate visual presentation of required stimuli for each of its assessments. Lastly, it leverages database storage and retrieval to visualize and aggregate data from multiple assessments and over many trials.

A vestibular electrode is described that is for implantation into a vestibular semi-circular canal. An intra-labyrinthine electrode carrier with a C-shaped cross-section has an inner concave surface and an outer convex surface, and is configured to fit through an electrode opening in an outer surface of the bony labyrinth into the perilymph fluid without breaking the membranous labyrinth so as to fit the inner concave surface of the electrode carrier adjacent to the membranous labyrinth and the outer convex surface adjacent to the bony labyrinth. There are one or more electrode contacts on a surface of the electrode carrier that are configured for electrical interaction with adjacent neural tissue.
