Brief Summary

The purpose of this study is to determine the incidence of vestibular dysfunction in traumatic brain injury patients admitted to acute inpatient rehabilitation. This study also seeks to validate the AbilityLab Vestibular Screening Tool (AVeST) and the AVeST+, tools designed to quickly screen individuals for vestibular dysfunction following traumatic brain injury.

Detailed Description

There are approximately 2.5 million hospital visits in the US each year for traumatic brain injury. Vestibular dysfunction is a common sequela of traumatic brain injury (TBI) affecting up to 50% of TBI patients at 5 years after injury. It is one of the most distressing problems for caregivers following TBI. Further complicating this issue is the fact that many individuals with TBI underestimate the severity of their balance deficits, which may further increase the risk of falls and subsequent injury. Sitting balance on admission to inpatient rehabilitation following TBI has been found to be one of the strongest predictors of functional status at discharge from inpatient rehabilitation. Due to the multifaceted presentation of vestibular dysfunction, evaluation is challenging, and there is currently no standardized approach to screening. While the incidence of vestibular dysfunction has been studied in mild TBI (mTBI) and sports related concussions, there is a gap in the literature regarding the incidence of vestibular dysfunction in moderate to severe TBI patients in acute inpatient rehabilitation.

The benefits of having an established vestibular dysfunction screening and rehabilitation program are multifold. Vestibular rehabilitation following TBI has demonstrated improvements in cognitive function, ability to return to activities of daily living, ability to return to work, and the need for assistance. While one prior single blind randomized controlled trial aimed to evaluate the effectiveness of a structured vestibular rehabilitation program in TBI individuals, there is a need for a large-scale study to evaluate the effectiveness of screening for vestibular dysfunction in order to create a systematic approach. Many TBI patients are not diagnosed with vestibular dysfunction until much later in their hospital course which impedes participation in therapy and likely has a detrimental effect on their rate of recovery. Identifying these patients earlier in their rehabilitation course will allow interventions that will improve and accelerate patient outcomes. An additional benefit of this study is to determine the incidence of vestibular dysfunction in moderate to severe TBI patients to outline the necessary resources to care for patients with this problem. Data collected will be utilized to validate the AVeST and the AVeST+. Additionally, this study will fill a gap in the literature in delineating the incidence of vestibular impairment in individuals with moderate to severe brain injury, a population heretofore not previously studied.
