Description

During the past 17 years, US military personnel experienced 305,000 mTBI (DVBIC, 2017), with an estimated 65% (187,000) involving some type of vestibular impairment (gaze, postural/dynamic instability) and symptoms (dizziness, vertigo, motion intolerance) (Mucha et al., 2014).

During the past 17 years, US military personnel experienced 305,000 mTBI (DVBIC, 2017), with an estimated 65% (187,000) involving some type of vestibular impairment (gaze, postural/dynamic instability) and symptoms (dizziness, vertigo, motion intolerance) (Mucha et al., 2014). These vestibular impairments and symptoms, which have been associated with poor outcomes following mTBI including longer recovery times (Lau et al., 2011), can be actively treated using targeted vestibular rehabilitation exercises (Alsalaheen et al., 2010). In fact, the investigators recently concluded an observational trial of military personnel and civilians with mTBI- Targeted Evaluation, Action and Monitoring of TBI (TEAM-TBI) project (W81XWH-14-2-0002) supporting the effectiveness of targeted vestibular rehabilitation exercises in military personnel and civilians with complex mTBI (Kontos et al., in press). Although these vestibular-focused rehabilitation exercises are commonly used by military medical personnel following complex mTBI, there are no well-designed studies that show how much these exercises should be performed to be effective in US military personnel. In short, the concussion rehabilitation field does not know how frequently or intensely the exercises should be performed in order for injured personnel to have the best recovery. In the current proposal, the investigators leverage our interdisciplinary team of experts from physical therapy, neurology, neuropsychology, and sports medicine and over 17 years of clinical and research experience to conduct a RCT comparing different frequency and intensity of targeted vestibular therapeutic exercises in military personnel and civilians. In so doing, the proposed study may inform a more precise approach for treating vestibular symptoms and impairments following mTBI that minimizes morbidity and accelerates recovery. Deliverables from the current study include: 1) outcome data regarding the efficacy of different frequencies and intensities of targeted vestibular exercises in both military personnel and civilians, and 2) evidence-based clinical practice guidelines (CPG) for prescribing vestibular therapeutic exercises.
