“…Noise overexposure can also damage the vestibular periphery (see summary by Stewart et al [ 27 ]). Preclinical work based on different animal models has demonstrated that, depending upon the noise characteristics, noise overexposure often leads to cellular damage in the peripheral vestibular system with a well-characterized effect on the response of otolith organs [ 28 , 29 , 30 , 31 ]. Studies using vestibular evoked myogenic potentials (VEMPs) [ 31 , 32 , 33 , 34 ] have provided evidence of the same in individuals with NIHL and in military veterans.…”

Noise-induced hearing loss (NIHL) is the most prevalent occupational disease in the world and firefighters are at increased risk of NIHL due to their frequent exposure to hazardous levels of noise during service. Adverse effects of NIHL include acceleration of age-related hearing loss and an increased risk of cognitive decline. A critical challenge in addressing NIHL is the delayed clinical presentation of symptoms and lack of sensitive tools for early detection. To study the early clinical symptoms of NIHL in this high-risk group, we collected hearing function data including behavioral audiometric thresholds and distortion product otoacoustic emissions (DPOAEs) in 176 firefighters during annual physical assessments. Results revealed significant deficits in cochlear outer hair cell function in the presence of normal audiograms. Additionally, 55% of firefighters self-reported changes in hearing, while 20% self-reported concerns about their balance. This study is the first to characterize DPOAEs in firefighters who display decreased DPOAE amplitudes with increasing years in the fire service. These effects were observed even when controlling for hearing loss and age and are suggestive of a link between hearing loss and occupational exposure to hazardous noise.

“…Following these injuries, there are varying degrees of physical, cognitive, and emotional impairment that may impede function (Scherer and Schubert 2009). Visual and vestibular impairments such as blurry vision, postural imbalance, vertigo, headache, and dizziness constitute the most common sequela seen in this population (Johnson et al 2014;Hoffer et al 2004). These impairments contribute to degradation of function by limiting activity and restricting participation in community and duty-related tasks.…”

Clinical effectiveness of virtual reality versus conventional clinic-based vestibular physical therapy on balance and function in active duty service members. A pilot randomized controlled trial

Virtual reality (VR) may be useful during rehabilitation of service members with persistent vestibular impairment following concussion. Thirty-eight active duty US military service members with persistent balance impairment resulting from concussion were randomized into three groups [Conventional Vestibular Physical Therapy (CVPT, n = 13), Virtual Reality Vestibular Physical Therapy (VRVPT, n = 12), and Hybrid Virtual Reality and Conventional Vestibular Physical Therapy (HybridVPT, n = 13)] and were treated twice weekly for 6 weeks. Changes in clinical measures such as Activities-specific Balance Confidence (ABC) Scale, Dizziness Handicap Inventory (DHI), Functional Gait Assessment (FGA), and Sensory Organization Test (SOT) were assessed from pre-, mid-, and post-treatment scores. A significant main time effect was observed demonstrating clinical improvement over time (ABC: p < .001, η2p = .54; DHI: p < .001, η2p = .57; FGA: p < .001, η2p = .74; SOT: p < .001, η2p = .35). Both CVPT and HybridVPT groups demonstrated significant improvements in patient-reported confidence and function earlier in the treatment course (p < .005). FGA significantly and incrementally improved at each assessment time point in all treatment groups. The SOT significantly improved early in treatment in the CVPT group only and pre-to-post-treatment in the CVPT and VRVPT groups only. The HybridVPT group did not demonstrate any significant improvement with time in the instrumented SOT measure. In the comparison of pre-to-post-effects of VRVPT and HybridVPT effects compared to CVPT, there was no clear superiority or inferiority observed in either of the experimental treatments. This preliminary work shows initial efficacy of using VR-based therapy for concussed individuals allowing future work to personalize treatment that may improve adherence and engagement to therapy.
