Summary

The overall objective is to evaluate objective dual-task turning measures for use as rehabilitative outcomes and as tools for return-to-duty assessments in individuals with mild traumatic brain injury (mTBI).This project consists of three goals examining the I) Diagnostic Accuracy, II) Predictive Capacity, and III) Responsiveness to Intervention of dual task turning measures in individuals with mTBI. The investigators hypothesize that objective measures of dual-task turning will have high diagnostic accuracy, predictive capacity, and responsiveness to intervention in people with mTBI.

Detailed description

The purpose of this project is to expand the investigators' prior preliminary work on wearable sensors to evaluate objective dual-task turning measures for use as rehabilitative outcomes and as tools for objective return-to-duty assessments following mild traumatic brain injury (mTBI). The investigators will assess the diagnostic accuracy, predictive capacity, and responsiveness to intervention of measures obtained from clinically feasible, dual-task turning tasks in an effort to evaluate the utility of turning measures for clinical return-to-duty decisions. This study is divided into two phases. For phase one, participants will be recruited from the general populations surrounding four sites (Oregon Health \& Science University, the University of Utah, Courage Kenny Research Center, and Fort Sam Houston), including active duty service members at Fort Sam Houston. For phase two, participants will be recruited from active duty service members referred to military medical treatment facilities (Warrior Recovery Center, Madigan Army Medical Center) for vestibular rehabilitation following mTBI. Phase One: Fifty civilian individuals with mTBI, 50 healthy control individuals, and 40 healthy control active duty service members will be recruited for phase one. Participants will complete a battery of clinical, neuropsychological, and balance tests, including three clinically feasible turning tasks while wearing inertial sensors. The investigators will evaluate the capability of objective, dual-task turning measures to discriminate between healthy controls and people with chronic mTBI, determine clinically relevant measures of dual-task turning based on clinometric properties (e.g., minimum detectable change), and determine whether active-duty SMs perform dual-task turning tasks differently than civilians, assess the capacity of dual-task turning measures to predict performance in a civilian-relevant task, and assess the capacity of dual-task turning measures to predict performance in a military-relevant task. Phase Two: Forty active-duty service members with mTBI referred to vestibular rehabilitation at the Warrior Recovery Center or Madigan Army Medical Center will be recruited for phase two. Participants will complete a selected turning task from phase one at the beginning and end of the treatment. The investigators will determine the clinically important difference of turning outcomes and compare the effect of rehabilitation to the minimum detectable change for each outcome.
