The objective of this study was to determine whether physical performance during virtual environment (VE) tasks in the Computer-Assisted Rehabilitation Environment (CAREN) could differentiate between service members (SMs) with a history traumatic brain injury (TBI) and without comorbid post-traumatic stress disorder (PTSD). Data were obtained by independent review clinical notes, outcomes, validated questionnaires from 214 SMs (208 males) TBI assessed CAREN 2010 2015. Three preliminary VEs...
Objective: The present study was designed to examine the impact that walking has on performance in auditory localization, visual discrimination, and aurally aided search tasks. Background: Auditory localization are critical skills frequently conducted by moving observers, but most laboratory studies of these tasks have been stationary listeners who were either seated or standing during stimulus presentation. Method: Thirty participants completed three different while still at a comfortable...
Background and Purpose: PTSD mTBI are persistent frequently comorbid after combat, yet current therapies often achieve only modest impact. A novel exposure-based “walk talk” cognitive therapy, Motion-Assisted, Multi-Modal Memory Desensitization Reconsolidation (3MDR), featuring participant-selected music pictures an eye movement (EM) task in immersive virtual environment, has shown efficacy treatment-resistant male veterans, but not been studied women or TBI. The EM is adapted from...
Virtual applications developed for balance training in the Computer Assisted Rehabilitation Environment (CAREN) require subjects to perform dynamic weight shifts. This retrospective case study examines use of CAREN as an adjunct conventional therapy three service members with upper and/or lower extremity amputations. All patients showed improved performance over several weeks training, and combined data can be characterized a power curve fit (y = 291.91x <sup...
In recent years, the delivery of evidence-based therapies targeting posttraumatic stress disorder (PTSD) has been focus Departments Defense in countries such as Canada, Netherlands, and United States. More than 66% military members continue to experience symptoms PTSD that significantly impact their daily functioning quality life after completing treatments. Innovative, engaging, effective treatments for are needed. Multimodal motion-assisted memory desensitization reconsolidation (3MDR) is...
Gait training is an essential part of the rehabilitation process for those with lower extremity (LE) amputations. For service members at Walter Reed Army Medical Center, Computer Assisted Rehabilitation Environment (CAREN) allows virtual reality to be incorporated into gait as adjunct conventional therapies. This retrospective case series examines self-selected velocities achieved in two different environments (VE) by 11 LE These VEs allowed participants progress from level walking more...
Mild traumatic brain injury (mTBI) is associated with significant financial cost and reduced military readiness impacts quality of life for active duty service members (SMs). Post-concussive symptoms can include vestibular impairments, such as chronic dizziness postural instability, which be compounded by psychological comorbidities like PTSD. Comprehensive evaluations are required to assess guide clinical decision-making. At the National Intrepid Center Excellence (NICoE), in addition...
To review the outcomes of rehabilitation for a service member with bilateral lower extremity amputations. A 25 year-old marine suffered right knee disarticulation and left transtibial amputation during military service. For two years, patient underwent comprehensive program at Walter Reed Army Medical Center. During course his rehabilitation, this took part in conventional physical therapy 16.5 months post-injury added clinical sessions Computer Assisted Rehabilitation Environment (CAREN)...
Service members (SMs) who have suffered mild traumatic brain injury due to blast exposure (b/TBI) often report post-concussive symptoms consistent with auditory, visual, or vestibular impairments even when they score within the normal range on traditional clinical tests of sensory function. One possible explanation for this discrepancy is that patients in low more than one modality may be severely impaired tasks require multisensory integration. This study evaluated unimodal and multimodal...
One of the most important functions spatial hearing is to facilitate rapid shift visual gaze in direction newly detected sound sources that might represent potential targets or threats our environment. Some dangerous can emerge when listeners are walking, so it useful know what impact walking have on audiovisual target detection and identification complex scenes. This study used a virtual environment consisting motorized treadmill surrounded by 180° projection screen mounted front...
Previous results have shown that observers who are walking at a constant pace on treadmill able to localize continuous sound sources and acquire identify audiovisual targets more quickly than standing stationary platform, with no apparent loss in accuracy. In order better understand the conditions where self-motion might enhance localization performance, follow-on experiment was conducted measured accuracy sounds of three different durations (250 ms, 1000 continuous) under four movement...
There has been considerable debate concerning the optimal load for power output during jump squat exercise. While most of research examined smith machine squats, few have free standing squats which may more carryover to actual sport tasks. a linear position transducer (LPT) is appropriate measuring displacement this device not validated free-standing squats. PURPOSE To determine validity combination LPT/force platform method as compared 2D video/force METHODS Seventeen college age males were...
Physical therapy following traumatic brain injury (TBI) can be negatively impacted by psychological symptoms, atypical symptom reporting, and response bias. We examined rates of Symptom Validity Test (SVT) failure in active duty military service members with a history mild-moderate TBI its impact on gait speed.Intensive Outpatient Program at the National Intrepid Center Excellence Walter Reed Military Medical Center.Participants were 84 classified as SVT pass ( n = 49) or fail...
