Device for computerized dynamic posturography and a method for balance assessment
InactiveUS20080228110A1Determining and training an individual's ability to recover balanceStable functionPerson identificationSensorsUniversal jointDynamic balance
A device for balance training and assessing dynamic balance by measuring a subject's ability to react to perturbations. A universal joint assembly is translated at the base of a support plate while a top plate on which the subject stands is fixed against translation. The universal joint permits the attached top plate to rotate about at least one and preferably multiple axes, and the subject must control balance following the translation of the universal joint. All components are housed in a one-piece platform assembly, made up of two plates in which the components are mounted. An existing force plate measurement system is placed on the top plate, and the subject stands thereon during use. A virtual environment, by image-creating devices, may be used to create a realistic sensation of tripping and general postural instability, or shifting of the support surface.

System for the physiological evaluation of brain function
The OculoKinetic Device is used to test an individual to evaluate brain functions and to identify the presence of a traumatic brain injury or disease which manifests itself through abnormal ocular responses to stimuli by using the high-speed tracking of an individual's eye movements, pupil size and reactivity, eye lid position and blink parameters and optionally along with other ocular elements, i.e., eyeball pressure, temperature, blood flow, etc. The eye movement stimulus protocol uses a target that moves in any direction of the two-dimensional plane and may use a color display or geometric shapes. In addition, the stimuli can be used in conjunction with cognitive testing, balance assessment, and other non-eye tests.
