Abstract Introduction Neurofeedback therapy (NFT) has demonstrated effectiveness for reducing persistent symptoms following traumatic brain injury (TBI); however, its reliance on NFT experts administration and high number of treatment sessions limits use in military medicine. Here, we assess the feasibility live Z-score training (LZT)—a variant that requires fewer can be administered by nonexperts—for a clinical setting. Materials Methods A single group design study was conducted to...
Objective: Previous research suggests that saccadic eye movements can be uniquely sensitive to impairment in chronic traumatic brain injury (TBI). This study was conducted examine across varying levels of cognitive load and TBI history/severity. We hypothesized mild moderate-severe would most pronounced under conditions high load.Methods: In total, 61 participants (including n = 20 with TBI, 15 26 uninjured controls) completed a battery conventional neuropsychological tests the Fusion n-Back...
Introduction: Computerized cognitive tests measuring manual response time (RT) and errors are often used in the assessment of visual attention. Evidence suggests that saccadic RT may also provide valuable information about This study was conducted to examine a novel approach multimodal attention incorporating concurrent measurements eye movements responses. Method: A computerized task, Bethesda Eye & Attention Measure (BEAM) v.34, designed evaluate key networks through measurement inhibition...
As a predominately young, physically active, and generally healthy population, service members (SMs) with vestibular dysfunction (VD) following TBI may not be accurately represented by the current civilian reference ranges on assessments of VD. This study enrolled SMs who were referred for rehabilitation mild/moderate TBI. The participants self-reported VD using Activities-specific Balance Confidence (ABC) scale Dizziness Handicap Inventory (DHI) followed evaluation performance computerized...
Objective Persistent post-concussive symptoms (PPCS) often include attention deficits, particularly orienting and executive attention. Research in other clinical populations has demonstrated that neurofeedback therapy (NFT) is effective at improving attention, although its effects on attentional networks patients with PPCS are unknown.Method In this single-group pilot study, we examined attention-related event-related potentials (ERPs) – N1 P3 cognitive outcomes following Live Z-score...
It was hypothesized that risk for age-related impairment in attention would be greater among those with remote history of mild TBI than individuals without head injury. Twenty-seven adults and a well-matched comparison group 54 uninjured controls completed computerized test visual while saccadic manual response times were recorded. Within the only, older age associated slower responses poorer inhibition. Saccadic slowing mitigated situations where timing location targets fully predictable....
Objective: To compare clinical outcomes between active duty service members receiving generalized versus individualized vestibular rehabilitation treatment (GVRT and IVRT, respectively) for persistent vestibular-related symptoms following mild traumatic brain injury (mTBI). Setting: An outpatient TBI clinic. Participants: Fifty-seven participants with mTBI were randomly assigned to the GVRT ( n = 28) or IVRT 29) group, stratified by dizziness-related impairment severity. Forty-two 21 per...
A specific variant of neurofeedback therapy (NFT), Live Z -Score Training (LZT), can be configured to not target EEG frequencies, networks, or regions the brain, thereby permitting implicit and flexible modulation activity. In this exploratory analysis, relationship between post-LZT changes in activity self-reported symptom reduction is evaluated a sample patients with persistent post-concussive symptoms (PPCS). Penalized regressions were used identify metrics associated physical, cognitive,...
Abstract Objective Depression, anxiety, and post-traumatic stress disorder (PTSD) are prevalent in individuals with a history of mild traumatic brain injury (mTBI). US military service members (SMs) at increased risk sleep deficiency, which may influence the relationship between mTBI psychological outcomes. This analysis examines interaction quantity on symptoms depression, PTSD. Method A sample 177 non-treatment seeking SMs completed Beck Depression Inventory (BDI), Anxiety (BAI), Post...
Abstract Objective The factor structure of the Connor-Davidson Resilience Scale (CD-RISC) varies between cultures, settings, and samples, yet has not been assessed in an active-duty United States (US) military sample. We used analysis to characterize resilience a generalizable sample service members (ADSMs) explored its associations with self-reported psychological outcomes ADSMs history mild traumatic brain injury (mTBI). Method Exploratory (EFA) 25-item CD-RISC was performed on...
ABSTRACT Introduction Headache is the most overwhelmingly reported symptom following mild traumatic brain injury (mTBI). The upper cervical spine has been implicated in headache etiology, and dysfunction may result neck pain that influences experience of headache. Sleep problem second mTBI. We explored contribution (as a potential proxy for dysfunction) on burden along with sleep quantity Materials Methods Retrospective data from repository consisting service members recruited primary care,...
INTRODUCTION: Concussion screening using the Military Acute Evaluation (MACE 2) and imaging modalities can be subjective, time intensive, monopolize scarce resources in a forward deployed environment. The Pupillary light reflex (PLR) has shown recent promise identifying mild traumatic brain injuries. METHODS: Freshman entering military service academy had baseline PLR measurements (starting pupillary diameter, ending average constriction velocity, dilation latency, percentage, T75 wave form)...
