Test and Evaluation of Non-Invasive Neuro-Assessment Devices (NINAD: Neurokinetics, Inc, iPAS

The long term goal for the Traumatic Injury Research Program (TIRP) is testing of novel devices for the identification and longitudinal assessment of traumatic brain injury (TBI). DoD (United States Department of Defense) has now tasked TIRP with the test and evaluation of these devices to assess reliability and validity. The objective of this effort is to test the reliability of the NKI, Inc, (NeuroKinetics, Inc) i-PAS device using a test/re-test protocol with healthy controls. The research design is test/re-test, with three assessments obtained on three separate visits. This will allow the assessment of reliability of both the device and the measure(s) that are computed from the input signals. Participants will be Healthy Controls (HC) as defined in the inclusion exclusion section. In this initial study, investigators will be administering standardized self-report instruments (Standard Form 36 - SF36, and Symptom Checklist 90r, or SCL-90r), standard three-lead EKG. In addition they will administer the NKI i-PAS specific protocol as delineated by NKI.
