QUANTITATIVE, NON-INVASIVE, CLINICAL DIAGNOSIS OF TRAUMATIC BRAIN INJURY USING VOG DEVICE FOR NEUROLOGIC TESTING

摘要

A portable VOG device is disclosed that will facilitate the effective and efficient screening for TBI in military personnel in forward deployed military settings or remote locations using minimally trained staff. This includes the establishment of a protocol that will provide cost effective pre-screening of military personnel prior to deployment to establish a baseline of brain function prior to possible future injury. The efficiency of the device will promote subsequent follow-up screening to assess the effectiveness of prescribed TBI treatment. Further protocols for diagnosis and rehabilitation applications using the same virtual reality portable device will allow more advanced usage for clinicians providing ongoing evaluation and treatment.

主权项

1. A method of diagnosis of mild traumatic brain injury or concussion comprising the steps of:
providing a head mounted goggle based stimulus generating eye tracking unit to the subject; presenting visual stimulus to the subject, wherein the visual stimulus is in the head mounted goggle based system and forms the optical target stimulus for at least two distinct tests including at least two of nystagmus tests, smooth pursuit tests, saccades tests, optokinetic tests, subjective visual horizontal and subjective visual vertical; obtaining objective physiologic response of the subject from the head mounted goggle unit based upon each of the visual stimulus presented to the subject in each test; and using the objective physiologic responses to diagnose the presence of mild traumatic brain injury or concussion.
