Relationships between vestibular issues, noise sensitivity, anxiety and prolonged recovery from mild traumatic brain injury among adults: a scoping review. Brain Inj 2024; 38:607-619. [PMID: 38597651 DOI: 10.1080/02699052.2024.2337905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 03/28/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND We investigated the extent of literature and findings on relationships between vestibular issues, noise sensitivity (NS), and anxiety. We were interested in how relationships among these factors impacted adults' recovery three months or more after mild traumatic brain injury (mTBI). METHODS We conducted a scoping review to evaluate the extent of evidence linking relationships between vestibular issues, NS and anxiety with recovery after mTBI. Data relating to study characteristics and key findings were extracted and used to inform a critical narrative synthesis of findings. RESULTS After screening and full-text review, we included two studies. Both studies considered the combination of vestibular issues, NS and anxiety and mTBI recovery. Vestibular issues, NS and anxiety were all significantly associated with one another and their presence was the strongest indicator that symptoms would extend beyond three-months after mTBI. CONCLUSION Few studies have focused on the relationships that vestibular issues, NS and anxiety have with one another and recovery after mTBI. Given the apparent strong relationships between these factors and prolonged recovery, we highlight this as an area warranting further investigation.

Abstract
OBJECTIVE Concussions are a common condition in athletes leading to symptoms including headache, dizziness, and sometimes vestibular deficits. Concussion management typically involves rest and a gradual return to activity among other interventions. This case series includes three patients who were evaluated using Mechanical Diagnosis and Therapy (MDT) after sport-related injuries involving concussion-like symptoms. MDT is a system of evaluating patients using repeated movements and sustained positions to assess symptomatic and mechanical changes. RESULTS Patients in this case series demonstrated rapid reduction of symptoms using variations of repeated cervical movements and sustained positions, which enabled them to return to play with a lasting resolution of symptoms. DISCUSSION/CONCLUSION This highlights the importance of a classification system for the appropriate treatment of these cases who did not require management using concussion protocol, as they were classified as cervical derangement.

Central sensorimotor integration assessment reveals deficits in standing balance control in people with chronic mild traumatic brain injury. Front Neurol 2022; 13:897454. [PMID: 36341095 PMCID: PMC9634071 DOI: 10.3389/fneur.2022.897454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 10/04/2022] [Indexed: 11/18/2022] Open
Abstract
Imbalance is common following mild Traumatic Brain Injury (mTBI) and can persist months after the initial injury. To determine if mTBI subjects with chronic imbalance differed from healthy age- and sex-matched controls (HCs) we used both the Central SensoriMotor Integration (CSMI) test, which evaluates sensory integration, time delay, and motor activation properties and the standard Sensory Organization Test (SOT). Four CSMI conditions evoked center-of-mass sway in response to: surface tilts with eyes closed (SS/EC), surface tilts with eyes open viewing a fixed visual surround (SS/EO), visual surround tilts with eyes open standing on a fixed surface (VS/EO), and combined surface and visual tilts with eyes open (SS+VS/EO). The mTBI participants relied significantly more on visual cues during the VS/EO condition compared to HCs but had similar reliance on combinations of vestibular, visual, and proprioceptive cues for balance during SS/EC, SS/EO, and SS+VS/EO conditions. The mTBI participants had significantly longer time delays across all conditions and significantly decreased motor activation relative to HCs across conditions that included surface-tilt stimuli with a sizeable subgroup having a prominent increase in time delay coupled with reduced motor activation while demonstrating no vestibular sensory weighting deficits. Decreased motor activation compensates for increased time delay to maintain stability of the balance system but has the adverse consequence that sensitivity to both internal (e.g., sensory noise) and external disturbances is increased. Consistent with this increased sensitivity, SOT results for mTBI subjects showed increased sway across all SOT conditions relative to HCs with about 45% of mTBI subjects classified as having an “Aphysiologic” pattern based on published criteria. Thus, CSMI results provided a plausible physiological explanation for the aphysiologic SOT pattern. Overall results suggest that rehabilitation that focuses solely on sensory systems may be incomplete and may benefit from therapy aimed at enhancing rapid and vigorous responses to balance perturbations.

The University of Kansas Health System Outpatient Clinical Concussion Comprehensive Protocol: An Interdisciplinary Approach. Health Serv Insights 2022; 15:11786329221114759. [PMID: 36034733 PMCID: PMC9411741 DOI: 10.1177/11786329221114759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Accepted: 06/30/2022] [Indexed: 11/24/2022] Open
Abstract
Objective: The concussion team at The University of Kansas Health System outpatient rehabilitation spine center is comprised of experienced multi-disciplinary experts including physical therapists and a speech language pathologist. The team set forth with a purpose of creating and organizing an internal physical therapy clinical recommendation protocol for initial evaluations and subsequent treatments for the concussed patient. The aim of this paper is to share these recommendation protocols with other therapy teams and provide a foundational layout for treating the patient with post-concussion symptoms in an outpatient physical therapy clinical setting. Study design: Clinical recommendation protocol provides guidance for patients ages 10+ from initial evaluation through discharge with emphasis on evidence-based research in the areas of: oculomotor, cervical, vestibular, post-concussion migraine influence, mood disorders(such as anxiety and depression), exertion, and cognitive communicative dysfunction. Results: Finding a written, comprehensive clinical resource protocol for post-concussion outpatient evaluation(s) and treatment strategies can be difficult. This document serves as a resource for other outpatient concussion rehabilitation clinics, providing rationale, and objective measurement tools, for assessing and treating concussion patients. To the authors’ knowledge, no other research has produced a practical, efficient evaluation tool to be utilized at bed side, condensing evidence-based research into an easy-to-use form. Conclusion: The University of Kansas Health System outpatient concussion rehabilitation center developed clinical recommendation protocols for concussion care. The intent was to standardize assessment and treatment for concussion patients and to share these objective measurement tools and procedures, focused on a team approach of concussion providers, as a clinical outline for both the novice and seasoned clinician specializing in the field of concussion work in an outpatient rehabilitation setting.

Abstract
OBJECTIVES To identify predictors of prolonged recovery (ie, >28 days) using patient demographic factors and healthy, norm-based cutoffs on a multimodal test battery in adolescents after sport-related concussions (SRCs). DESIGN Retrospective cohort. Patients were deemed recovered after successful completion of return-to-play/school protocols and received medical clearance. SETTING Community concussion clinic. PATIENTS Male and female adolescent student athletes diagnosed with a SRC and evaluated within 1 week of injury. INDEPENDENT VARIABLES Patient demographics, medical history, injury description, computerized neurocognitive testing, vestibular/ocular testing, and symptoms at initial clinical visit. MAIN OUTCOME MEASURES Performance on clinical testing to predict recovery duration, classified as normal (<28 days) or prolonged (>28 days). RESULTS A total of 201 adolescent student athletes (age = 15.3 ± 1.4 years) were included (female 35%). Average recovery duration for the entire cohort was 22.3 ± 13.3 days, with 22% (n = 45) of adolescent student athletes taking >28 days to recover. The final model was 88.3% accurate in classifying normal and prolonged recovery. Predictor variables included sex, loss of consciousness, history of ocular disorder, history of concussion, performance on visual motor speed composite, visual motion sensitivity symptom provocation and near point of convergence distance, number-naming total time, and symptom count. CONCLUSIONS These findings suggest that using norm-based cutoffs from cognitive, oculomotor, and vestibulo-ocular testing and symptom reporting, clinicians can accurately predict a prolonged recovery (sensitivity = 81%) and normal recovery (specificity = 83%) in an adolescent, SRC cohort.

Abstract
As a predominately young, physically active, and generally healthy population, service members (SMs) with vestibular dysfunction (VD) following a TBI may not be accurately represented by the current civilian reference ranges on assessments of VD. This study enrolled SMs who were referred for vestibular rehabilitation following a mild/moderate TBI. The participants self-reported VD using the Activities-specific Balance Confidence (ABC) scale and the Dizziness Handicap Inventory (DHI) followed by evaluation of vestibular performance using computerized dynamic posturography sensory organizational test (CDP−SOT). Retrospective analysis of these outcomes comparing the study sample of SMs to the reported civilian samples revealed SMs self-reported lower VD with significantly higher balance confidence (ABC: 77.11 ± 14.61, p < 0.05) and lower dizziness (DHI: 37.75 ± 11.74, p < 0.05) than civilians. However, the SMs underperformed in performance-based evaluations compared to civilians with significantly lower CDP−SOT composite and ratio scores (COMP: 68.46 ± 13.46, p < 0.05; VIS: 81.36 ± 14.03, p < 0.01; VEST: 55.63 ± 22.28, p < 0.05; SOM: 90.46 ± 10.17, p < 0.05). Correlational analyses identified significant relationships between the ABC and CDP−SOT composite (r = 0.380, p < 0.01) and ratio scores (VIS: r = 0.266, p < 0.05; VEST: r = 0.352, p < 0.01). These results highlight the importance of recognizing and understanding nuances in assessing VD in SMs to ensure they have access to adequate care and rehabilitation prior to returning to duty.

Abstract
Concussion screening among collegiate lacrosse athletes is a major safety priority. Although attention has been directed at concussion management following injury, less is known about the association between cognition and balance during preseason screening. The purpose of the study was to assess the relationship between balance and neurocognition among collegiate male lacrosse players and to examine predictive determinants of postural stability. Participants included a convenience sample of 49 male collegiate Division 3 lacrosse players who completed a demographic survey and performed the immediate postconcussion test (ImPACT) and instrumented Sensory Organization Test (SOT). There was a significant association between balance SOT performance and both verbal memory (r = .59, p < .01) and visual motor speed scores (r = .43, p < .05). Significant correlations between verbal memory and SOT Conditions 2, 5, and 6 were also noted (all p < .05). Verbal memory predicted 33% of the variance in the SOT composite balance score (p < .001). Our results indicate a significant relationship exists between postural stability and both verbal memory and visual processing speed among collegiate male lacrosse players and supports vestibulocortical associations. Findings warrant ongoing performance and executive function tracking and can serve as a conduit for integrated sensorimotor and dual-task training.

Abstract
OBJECTIVE To determine whether the Vestibular/Ocular Motor Screening (VOMS) tool demonstrates concurrent validity with the Dizziness Handicap Inventory (DHI) in a sample of concussed athletes referred for vestibular therapy and whether DHI items were predictive of VOMS outcomes. DESIGN Cross-sectional cohort study. SETTING Concussion specialty/vestibular therapy clinic. METHODS Adolescents (n = 55; 15.4 ± 1.6 years) with diagnosed sport-related concussion (SRC) with vestibular symptoms and/or impairment between October 2018-February 2020. Patients completed VOMS and DHI at initial visit. Seven individual VOMS and twenty-five DHI items, VOMS and DHI total score and three DHI sub-scales, were compared with Spearman correlations. Three backwards linear regression (LR) models were built to predict 1. VOMS vestibular symptoms, 2. VOMS ocular symptoms, and 3. near-point of convergence-distance (NPC-distance) using individual DHI items as predictors. RESULTS Spearman correlations (p) identified DHI items with moderate to strong associations for VOMS items. DHI sub-scales demonstrated moderate-to-strong correlations with VOMS items (p = 0.30-0.59). Total DHI score demonstrated a moderate-to-strong association with HSAC (p = 0.30), VSAC (p = 0.32), and SP (p = 0.61). Results from the LRs predicting VOMS ocular symptoms (R (Alsalaheen et al., 2010) = 0.56; p < 0.001), and VOMS vestibular symptoms (R (Alsalaheen et al., 2010) = 0.23; p = 0.01), and NPC-distance (R (Alsalaheen et al., 2010) = 0.56; p < 0.001) included significant DHI predictors. CONCLUSIONS There was moderate-to-strong associations between VOMS and 56% of DHI items (i.e., p > 0.30).

Abstract
OBJECTIVE To characterize the relationship between dizziness severity and cognitive dysfunction in vestibular migraine (VM) patients. METHODS Dizziness Handicap Inventory (DHI) and Cognitive Failures Questionnaire (CFQ) scores were compared pre- and post-treatment in a cohort of definite VM patients who underwent evaluation in a multidisciplinary clinic from 2016 to 2020. RESULTS 44 patients were included. DHI reduction of 11.96 (SD 11.49) (p < 0.001) from an initial mean of 58.36 (22.05) and CFQ reduction of 4.57 (12.20) (p = 0.017) from an initial mean of 47.66 (19.12) were demonstrated. Both pre- and post-treatment DHI scores correlated with pre- and post-treatment CFQ scores (r = 0.537, p < 0.001 and r = 0.667, p < 0.001, respectively). Change in DHI score correlated with change in CFQ score (r = 0.351, p = 0.019). CONCLUSIONS Cognitive dysfunction in VM patients is correlated with dizziness severity. The DHI may fail to thoroughly assess cognitive dysfunction in VM patients. Additionally, multidisciplinary treatment of VM reduces both dizziness severity and cognitive dysfunction.

Abstract
BACKGROUND Individuals who have experienced a traumatic brain injury (TBI) often have residual balance problems. It remains unclear whether these balance problems are driven by vestibular dysfunction or gait automaticity deficits, particularly in the chronic stages of TBI recovery, because most studies include only acute/subacute cases. OBJECTIVES Compare performance on the Sensory Organization Test vestibular score and Dual-Task test in individuals with and without subjective balance problems at least 1 year after a TBI. Investigate the ability of each test to predict perceived balance problems. DESIGN Prospective cohort study. SETTING Rehabilitation department within a single institution. PARTICIPANTS Fifty adults (21-71 years) with a history of mild, moderate, or severe TBI 1 to 5 years following nonpenetrating TBI. INTERVENTIONS N/A. METHODS Measures included the Dual-Task test, Sensory Organization Test, Neurobehavioral Symptom Inventory, Dizziness Handicap Inventory, and assessments of four cognitive domains and depression. Participants who endorsed "feeling dizzy" and "loss of balance" on the Neurobehavioral Symptom Inventory were classified as symptomatic (n = 26) and others as asymptomatic (n = 24). T-tests, chi-square, and regression analyses predicting the Dizziness Handicap Inventory total score were performed. RESULTS Dual-task gait cost was negatively associated with the Dizziness Handicap Inventory (P = .044), controlling for depression and gender, whereas vestibular scores failed to predict balance-related disability. Symptomatic individuals endorsed more balance problems (P < .001) and depression symptoms (P = .007), had poorer dual-task cognitive output (P = .036), and slower dual-task gait velocity (P = .036) than asymptomatic participants. Groups did not differ on Sensory Organization Test scores. CONCLUSIONS The nature of balance problems in chronic TBI may be related to automaticity of gait. These findings suggest that patients in the chronic stages of TBI may benefit from dual-task assessments and interventions. Balance rehabilitation should be tailored to patient needs and assess cognition and affect.

Longitudinal fixel-based analysis reveals restoration of white matter alterations following balance training in young brain-injured patients. Neuroimage Clin 2021; 30:102621. [PMID: 33780865 PMCID: PMC8022866 DOI: 10.1016/j.nicl.2021.102621] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 02/24/2021] [Accepted: 03/03/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND OBJECTIVES Traumatic brain injury (TBI) is one of the leading causes of death and disability in children and adolescents. Young TBI patients suffer from gross motor deficits, such as postural control deficits, which can severely compromise their daily life activities. However, little attention has been devoted to uncovering the underlying white matter changes in response to training in TBI. In this study, we used longitudinal fixel-based analysis (FBA), an advanced diffusion imaging analysis technique, to investigate the effect of a balance training program on white matter fibre density and morphology in a group of young TBI patients. METHODS Young patients with moderate-to-severe TBI (N = 17, 10 females, mean age = 13 ± 3 years) and age-matched controls (N = 17) underwent a home-based balance training program. Diffusion MRI scans together with gross motor assessments, including the gross motor items of the Bruininks-Oseretsky Test of Motor Proficiency, the Activities-Specific Balance Confidence (ABC) Scale, and the Sensory Organization Test (SOT) were administered before and at completion of 8-weeks of training. We used FBA to compare microstructural differences in fibre density (FD), macrostructural (morphological) changes in fibre cross-section (FC), and the combined FD and FC (FDC) metric across the whole brain. We then performed a longitudinal analysis to test whether training restores the white matter in the regions found to be damaged before treatment. RESULTS Whole-brain fixel-based analysis revealed lower FD and FC in TBI patients compared to the control group across several commissural tracts, association fibres and projection fibres, with FD reductions of up to 50%. Following training, TBI patients showed a significant interaction effect between Group and Time for the SOT test, as well as significant increases in macrostructural white matter (i.e., FC & FDC) in left sensorimotor tracts. The amount of change in FC and FDC over time was, however, not associated with behavioural changes. DISCUSSION Our fixel-based findings identified both microstructural and macrostructural abnormalities in young TBI patients. The longitudinal results provide a deeper understanding of the neurobiological mechanisms underlying balance training, which will allow clinicians to make more effective treatment decisions in everyday clinical practice with brain-injured patients.

Ahluwalia R, Miller S, Dawoud FM, Malave JO, Tyson H, Bonfield CM, Yengo-Kahn AM. A Pilot Study Evaluating the Timing of Vestibular Therapy After Sport-Related Concussion: Is Earlier Better? Sports Health 2021; 13:573-579. [PMID: 33682532 DOI: 10.1177/1941738121998687] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Vestibular dysfunction, characterized by nausea, dizziness, imbalance, and/or gait disturbance, represents an important sport-related concussion (SRC) subtype associated with prolonged recovery. Vestibular physical therapy promotes recovery; however, the benefit of earlier therapy is unclear. HYPOTHESIS Earlier vestibular therapy for young athletes with SRC is associated with earlier return to play (RTP), return to learn (RTL), and symptom resolution. STUDY DESIGN Retrospective cohort study. LEVEL OF EVIDENCE Level 3. METHODS Patients aged 5 to 23 years with SRC who initiated vestibular rehabilitation therapy (VRT) from January 2019 to December 2019 were included and patient records were reviewed. Therapy initiation was defined as either early, ≤30 days postinjury, or late (>30 days). Univariate comparisons between groups, Kaplan-Meier plots, and multivariate Cox proportional hazard modeling were performed. RESULTS Overall, 23 patients (10 early, 13 late) aged 16.14 ± 2.98 years and 43.5% were male patients. There was no difference between group demographics or medical history. Median initial total and vestibular symptom scores were comparable between groups. The late therapy group required additional time to RTP (110 days [61.3, 150.8] vs 31 days [22.5, 74.5], P = 0.03) and to achieve symptom resolution (121.5 days [71, 222.8] vs 54 days [27, 91], P = 0.02), but not to RTL (12 days [3.5, 26.5] vs 17.5 days [8, 20.75], P = 0.09). Adjusting for age and initial total symptom score, earlier therapy was protective against delayed symptom resolution (P = 0.01). CONCLUSION This pilot study suggests that initiating VRT within the first 30 days after SRC is associated with earlier RTP and symptom resolution. Further prospective trials to evaluate if even earlier VRT should be pursued to further improve recovery time. CLINICAL RELEVANCE Clinicians should screen for vestibular dysfunction and consider modifying follow-up schedules after SRC to initiate VRT within a month of injury for improved outcomes.

Normative values for the Sensory Organization Test in an active duty military cohort. Gait Posture 2021; 85:31-37. [PMID: 33513530 DOI: 10.1016/j.gaitpost.2021.01.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 01/11/2021] [Accepted: 01/14/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND Computerized dynamic posturography is commonly used to assess balance in service members, but normative values for the military population have not been established. RESEARCH QUESTION What are the normative values for the Motor Control Test (MCT), Sensory Organization Test (SOT) and the enhanced SOT (eSOT) within the military population and at which point do they differ? METHODS Cross-sectional study. 237 active duty service members (78 % male) completed the MCT, SOT and the eSOT with the sway manipulated at a gain of 1.2, 1.4, 1.6, 1.8, or 2.0. A Mann-Whitney U test was used to compare the means of men and women for the SOT and MCT composite scores. A Kruskal-Wallis H test was used to compare the means of age groups for the SOT composite score. An independent t-test was used to compare the SOT composite scores from our military population to the manufacturer's normative (civilian) data. The means and standard deviations for the eSOT scores were reported for each gain. Paired-samples t-tests were performed to compare the SOT composite score with the eSOT composite score for each level of gain. RESULTS There was no difference between SOT composite scores for men and women (Mann-Whitney U = 4363.50, p = 0.19) or among age groups (Kruskal-Wallis = 2.77, p = 0.25). The mean SOT composite scores were not different from the manufacturer's normative values (p = 0.155). SOT composite scores were significantly higher than eSOT composite scores for gains of 1.4 (t = 3.16, p = 0.003), 1.6 (t = 5.73, p < 0.001), 1.8 (t = 5.26, p < 0.001) and 2.0 (t = 5.89, p < 0.001). MCT composite scores were lower in the 18-26 year old than the 36-45 year old age group (p = 0.013). SIGNIFICANCE This study establishes normative values for the MCT, SOT and eSOT in active duty military service members. The results suggest that the manufacturer's normal values are appropriate for making judgments about the postural stability of service members.

Abstract
OBJECTIVE Characterize the relationship between cognitive dysfunction and the dizziness severity in Meniére's disease (MD) patients. STUDY DESIGN Retrospective review. SETTING University-based tertiary medical center. PATIENTS Three hundred patients were evaluated for MD from 2015 to 2019. Excluding comorbid or alternative vestibular disorders, 29 patients with definite MD and available pre- and postintervention data were included for analysis. INTERVENTIONS A progressive protocol of salt restriction, diuretics, steroid and/or gentamycin injection, and endolymphatic sac decompression for those refractory to medical therapy. MAIN OUTCOME MEASURES Quality of life measured with the Dizziness Handicap Inventory (DHI) and cognitive function measured with the Cognitive Failures Questionnaire (CFQ). Pre- and posttreatment DHI and DHI subscale scores and change in these scores were correlated with pre- and posttreatment CFQ scores and change in CFQ with therapy. RESULTS Analysis showed a number of limited associations between improvement in DHI and improvement in CFQ. Total DHI scores failed to correlate scores or variation in scores with change in CFQ (p = 0.091 and p = 0.085, respectively). Improvement in the CFQ false-triggering domain was significantly associated with improvement in the DHI physical subscale (r = 0.491, p = 0.007) and was nonsignificantly associated with improvement in total DHI and DHI emotional subscale scores (r = 0.422, p = 0.016 and r = 0.399, p = 0.032). CONCLUSIONS The DHI correlates with several pre- and posttreatment measures of cognitive dysfunction (CFQ) in MD patients. However, change in DHI and CFQ with therapy correlate poorly. Overall, the commonly used DHI may fail to adequately assess cognitive dysfunction in MD patients possibly due to factors not directly implicated by measures of vestibular dysfunction, such as central nervous system or cognitive dysfunction; however, the specific physical and emotional subscales may offer helpful insight into cognitive dysfunction change/improvement with treatment.

Abstract
BACKGROUND After concussion many people have cervicogenic headache, visual dysfunction, and vestibular deficits that can be attributed to brain injury, cervical injury, or both. While clinical practice guidelines outline treatments to address the symptoms that arise from the multiple involved systems, no preferred treatment sequence for post-concussion syndrome has emerged. PURPOSE This study sought to describe the clinical and patient-reported outcomes for people with post-concussion symptoms after a protocol sequenced to address cervical dysfunction and benign paroxysmal positional vertigo within the first three weeks of injury, followed by integrated vision and vestibular therapy. STUDY DESIGN Retrospective longitudinal cohort analysis. METHODS Records from a concussion clinic for 38 patients (25 male 13 female, aged 26.9±19.7 years) with post-concussion symptoms due to sports, falls, assaults, and motor vehicle accident injuries were analyzed. Musculoskeletal, vision, and vestibular system functions were assessed after pragmatic treatment including early cervical manual therapy and canalith repositioning treatment-when indicated-integrated with advanced vision and vestibular rehabilitation. Patient-reported outcomes included the Post-Concussion Symptom Scale (PCSS) for general symptoms; and for specific symptoms, the Dizziness Handicap Index (DHI), Convergence Insufficiency Symptom Scale (CISS), Activities-specific Balance Confidence scale (ABC), and the Brain Injury Vision Symptom Survey (BIVSS). Paired t-tests with Bonferroni correction to minimize familywise error (p<0.05) were used to analyze the clinical and patient-reported outcomes. RESULTS After 10.4±4.8 sessions over 57.6±34.0 days, general symptoms improved on the PCSS (p=0.001, 95%CI=12.4-30.6); and specific symptoms on the DHI (p<0.001, 95%CI=14.5-33.2), CISS (p<0.002, 95%CI=7.1-18.3), ABC (p<0.024, 95%CI=-.3 - -.1), and BIVSS (p<0.001, 95%CI=13.4-28.0). Clinical measures improved including cervical range-of-motion (55.6% fully restored), benign paroxysmal positional vertigo symptoms (28/28, fully resolved), Brock string visual convergence (p<0.001, 95%CI=3.3-6.3), and score on the Balance Error Scoring System (p<0.001, 95%CI=5.5-11.6). CONCLUSION A rehabilitation approach for post-concussion syndrome that sequenced cervical dysfunction and benign paroxysmal positional vertigo treatment within the first three weeks of injury followed by integrated vision and vestibular therapy improved clinical and patient-reported outcomes. Level of Evidence: 2b.

Abstract
The purpose of this study is to demonstrate whether neurocognitive evaluation can confirm the association between neurocognitive level and postural control and to analyze the relationship between neurocognitive level and acute musculoskeletal injury in male non-net sports athletes. Seventy-seven male non-net sports athletes participated in this study. The Standardized Assessment of Concussion (SAC), Landing Error Scoring System (LESS), Balance Error Scoring System (BESS), and Star Excursion Balance Test (SEBT) were used for testing; we collected data related to injury history for six months after testing. Pearson's correlation analysis, logistic regression, and the independent sample t-test were used for statistical analysis. The correlation between SAC and SEBT results was weak to moderate (p < 0.05). Eleven of the seventy-seven participants experienced acute lower limb injuries. SAC, LESS, BESS, and SEBT results have no effect on the occurrence of acute lower extremity injuries (p > 0.05) and were not statistically different between the injured and non-injured groups (p > 0.05). Therefore, using the SAC score alone to determine the risk factor of lower extremity injuries, except in the use of assessment after a concussion, should be cautioned against.

Abstract
Neuropsychological assessment is a key component in a comprehensive, multidisciplinary approach to assessment of sport-related concussion (SRC). Currently computerized tests are the most commonly used modality of neurocognitive testing and involve both baseline and postinjury assessments. A comprehensive neuropsychological assessment should not only include neurocognitive testing but also incorporate symptom inventories, vestibular-ocular screening, and a psychological evaluation. Neuropsychological assessments are most effective when completed by a Clinical Neuropsychologist, given their specialized training in test interpretation and conceptualization of the psychological, cognitive, behavioral, physiologic, as well as neurologic principals when treating and managing SRC.

Abstract
OBJECTIVE Following concussion, there is an array of sequelae including symptom burden, neurocognitive dysfunction, and balance impairment. However, the magnitude of change in balance performance has yet to be explored fully regarding its relationship with neurocognitive functioning or symptom endorsement. The present study hypothesized that the magnitude of change in balance performance from baseline to post-trauma would have unique predictive power in identifying acute clinical outcomes. METHOD Sixty-eight college athletes completed annual preparticipation baseline testing and were later diagnosed with a concussion. RESULTS Linear regressions determined that the magnitude of change in balance performance was a better predictor of neurocognitive dysfunction and endorsement of "balance problems" than post-trauma balance performance alone. CONCLUSIONS These findings highlight the importance of incorporating balance measurements during preparticipation baseline assessment.

Abstract
BACKGROUND Gait impairment is common after concussion. "Dizziness" is associated with prolonged recovery after concussion. Most often each of these symptoms is considered to be of vestibular origin. However, whether or not there are psychological etiologies of gait instability that complicate concussion recovery has been less fully explored. METHODS A chart review was performed of all patients seen between 2017 and 2019 in a weekly pediatric traumatic brain injury clinic. RESULTS Of eighty-four patients with traumatic brain injury, five were found to have developed a classic psychogenic gait. All were adolescents at the time of diagnosis. Recognition of this complication led to modification/initiation of physical therapy and/or mental health intervention and eventual resolution for all patients. CONCLUSION Although uncommon, psychogenic gait disorders may complicate concussion recovery in adolescents likely at a higher rate than their occurrence in the general population. This association has not been previously reported. Accurate diagnosis of psychogenic gait likely improves outcomes in this subset of patients with concussion.

Abstract
Adults exposed to blast and blunt impact often experience mild traumatic brain injury, affecting neural functions related to sensory, cognitive, and motor function. In this perspective article, we will review the effects of impact and blast exposure on functional performance that requires the integration of these sensory, cognitive, and motor control systems. We describe cognitive-motor integration and how it relates to successfully navigating skilled activities crucial for work, duty, sport, and even daily life. We review our research on the behavioral effects of traumatic impact and blast exposure on cognitive-motor integration in both younger and older adults, and the neural networks that are involved in these types of skills. Overall, we have observed impairments in rule-based skilled performance as a function of both physical impact and blast exposure. The extent of these impairments depended on the age at injury and the sex of the individual. It appears, however, that cognitive-motor integration deficits can be mitigated by the level of skill expertise of the affected individual, suggesting that such experience imparts resiliency in the brain networks that underly the control of complex visuomotor performance. Finally, we discuss the next steps needed to comprehensively understand the impact of trauma and blast exposure on functional movement control.

Abstract
Background Different measures have been used to quantify body balance; some of which use technology to measure postural sway, others are physical performance or self-reported. However, there is little information on the best postural sway measures associated with aging, physical performance, and cognitive function measures. Objective To evaluate the relationship between postural sway measures and aging, physical performance, and cognitive function measures. Methods A total of 51 subjects (53% female, mean age 53.2 ± 21 years) participated in this cross-sectional study. The participants completed the Activities-specific Balance Confidence (ABC) Scale questionnaire, the Functional Gait Assessment (FGA), the Montreal Cognitive Assessment (MoCA) test, and gait speed. Afterward, the participants performed 8 balance exercises, and their postural sway was measured using a force plate. Spearman's rank correlation coefficient was used to examine the relationship between the study variables. Results Age was negatively associated with cognitive function, gait speed, ABC scores, and FGA scores. In addition, cognitive ability was associated positively with ABC scores (r = 0.38, p ≤ 0.01). Age, FGA scores, and gait speed were significantly associated with the postural sway of the AP direction in some exercises and in all exercises in the ML directions (p < 0.05). The cognitive function and ABC scores were significantly associated with only postural sway measures in the ML direction (p < 0.05). Conclusion The postural sway measures in the lateral direction had more and stronger associations with age, physical performance, and cognitive function measures compared to those in the AP direction.

Abstract
Purpose Vestibular impairments have been associated with a variety of cognitive deficits, most notably deficits in visuo-spatial memory. The Neuropsychological Vertigo Inventory (NVI) was developed to measure self-reported cognitive deficits in patients with dizziness and/or vertigo. The original French language version of the NVI includes 28 items and 7 subscales. The purpose of the present investigation was to determine whether the statistical assessment of an English language version supported the presence of the same cognitive constructs as the French version of the NVI. Method The English language adaptation of the NVI (referred to here as the NVIe) was administered to an unselected sample of 280 patients that were being evaluated for dizziness and/or vertigo in a tertiary care dizziness clinic. The individual item scores from the NVIe were subjected to an exploratory factor analysis (EFA). Results The results of the data analysis supported a 22-item NVIe consisting of 4 constructs: affective state, temporal memory, spatial memory, visual spatial cognition. Conclusions The NVIe is a new tool for screening cognitive constructs that may be affected by vestibular impairments. Prior to clinical implementation of the NVIe, additional studies of reliability and convergent validity are needed.

Abstract
Purpose The purpose of this project was to explore the association between the perception of motion during caloric testing and two tasks associated with central vestibular processing: postural stability and visuospatial memory. Method This was a prospective study of 25 patients who were found to have nonvestibular etiologies of their symptoms and normal vestibular function test results and who underwent caloric testing with a mean maximum slow phase eye velocity for each irrigation of 15° or greater. Following each caloric irrigation, patients were asked whether they had any sensation of movement. Patients were grouped based on the presence or absence of motion during the caloric exam (motion perception vs. absent perception). Postural stability was assessed using computerized dynamic posturography, and visuospatial memory was assessed using a memory match card game application. Results There were no significant differences between groups on any measures of peripheral vestibular function. However, the Absent Perception Group showed greater postural instability during Condition 5 of posturography and performed significantly worse on a task of visuospatial working memory. Both age and absence of motion perception predicted abnormal performance on measures of postural stability and visuospatial working memory. Conclusions There appears to be clinical implications to a lack of motion perception during the caloric exam in patients with an otherwise normal peripheral vestibular system. Based on the current findings, we are unable to determine whether differences in postural stability and visuospatial memory were due to age or a central vestibular processing deficit.

Pitt W, Chou LS. A case-control study of gait balance control in veterans with chronic symptoms following mTBI. Gait Posture 2020; 76:188-192. [PMID: 31862668 DOI: 10.1016/j.gaitpost.2019.12.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 09/27/2019] [Accepted: 12/04/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Numerous investigations suggest mild traumatic brain injury (mTBI) may result in persistent gait balance control deficits. Furthermore, military Veterans with symptoms of chronic mTBI often present with physical symptoms that may be associated with impaired gait balance control which may lead to prolonged recovery, difficulty performing activities of daily living, and increased disability. It is therefore important to objectively quantify gait balance deficits in Veterans with chronic mTBI. RESEARCH QUESTION Is gait balance control impaired in a group of Veterans with chronic symptoms of mTBI when compared to healthy matched Veterans? METHODS Eight Veterans with symptoms of chronic mTBI (1 F/7 M) and eight healthy matched Veterans (1 F/7 M) completed a gait balance assessment under single- (ST) and dual-task (DT) conditions. Gait balance control was quantified with whole body center of mass (COM) total medial-lateral (ML) displacement and peak ML velocity, which were calculated from camera-based motion capture. RESULTS Veterans with chronic mTBI walked with greater ML COM displacement (approximately 25 % increase) in both ST and DT walking (main effect of group, p = 0.018) when compared to healthy Veterans. The peak ML COM velocity was affected for both groups by performing a concurrent cognitive task (interaction effect, p = .012). Slower ML COM velocities in healthy Veterans suggest the adoption of a conservative balance control strategy, while faster ML COM velocities for Veterans with chronic mTBI may indicate a diminished ability to control ML momentum. SIGNIFICANCE Increased frontal plane COM motion under both ST and DT walking was observed in Veterans with chronic mTBI symptoms many years after injury. This suggests gait balance control may be adversely affected during divided attention gait and highlights the need for comprehensive gait analysis in the management of these individuals.

Abstract
BACKGROUND The incidence of fear of falling (FOF) is high among people with cancer. However, factors that are associated with FOF in people with cancer has not yet been investigated. Therefore, the objective of this study was to identify the associated factors with FOF in people with cancer. METHOD This is a secondary analysis of the International Mobility in Aging Study (IMIAS) study. A total of 175 people self-identified as patients with cancer (mean age: 69.3 years, women: 50.2%) and 177 healthy age-matched group. FOF measured using the Falls Efficacy Scale-International (FES-I) was the primary outcome. Potential variables/factors for consistency known to be associated with FOF (cognitive status, depression, physical performance, the number of falls in the last year, visual acuity and grip strength) were assessed. Simple linear regression was used to identify factors associated with FOF. Variables with p-value <0.05 were then included in a multiple linear regression adjusted for the study confounders (study site, sex, and age). RESULTS For people with cancer, FES-I was significantly associated with the Leganes Cognitive Test, The Short Physical Performance Battery (SPPB) total scores and the number of falls reported in the past 12 months (P-value <0.05). For the healthy group, FOF was only associated with depression and SPPEB. CONCLUSION FOF is multifactorial in people with cancer and it is associated with cognitive status, physical performance and number of falls in the last year. Healthcare providers for patients with cancer should evaluate all potential factors associated with FOF and manage it.

Abstract
A complex diagnosis such as concussion requires a multidisciplinary patient-centered approach to maximize health outcomes. There is growing evidence to support the role of the Physical Therapist as a key member of the team of healthcare professionals managing children and adolescents with a protracted recovery following concussion. Symptoms such as headache, dizziness, neck pain, gaze instability, balance dysfunction, and fatigue can be addressed through a multimodel approach. This article provides an overview of the targeted pathways of examination and treatment of individuals with a concussion through vestibular rehabilitation, cervicogenic rehabilitation, exertional training, and patient education.

Abstract
BACKGROUND Concussion can cause vestibular dysfunction and oculomotor abnormalities which can lead to dizziness and protracted recovery time. There are few clinically useful, functional measures of the vestibulo-ocular reflex (VOR) post-concussion. PURPOSE The purpose of this study was to examine the gaze stabilization test (GST) in those referred for vestibular physical therapy following concussion, to determine the association between GST and other measures of recovery following concussion, and to examine the effect of demographic variables on GST performance. RESEARCH DESIGN Retrospective chart review. STUDY SAMPLE One hundred fifty-eight individuals who sustained a concussion and were referred to vestibular physical therapy. DATA COLLECTION AND ANALYSIS Horizontal and vertical GST scores (HGST and VGST), neurocognitive testing results, and demographic data were extracted retrospectively from the patient health record. Correlations between GST velocity and neurocognitive test results and between GST and patient-reported outcomes were examined. Differences in GST performance among patient subgroups were examined using one-way analysis of variance. RESULTS Subjects included individuals aged 12 to 43 years (mean = 20, standard deviation [SD] = 7), with most having sport-related concussion (67%). The mean time from injury to GST was 215 days (SD = 241) and the mean time from physical therapy evaluation to GST was 48 days (SD = 54). HGST and VGST had a weak positive correlation to the Activities-Specific Balance Confidence Scale (r = 0.20, r = 0.21) and weak negative correlation to the Dizziness Handicap Inventory (r = -0.18, r = -0.22). HGST had a weak positive correlation to the visual motor processing speed domain of the immediate post-concussion assessment and cognitive test (r = 0.20). Male patients achieved significantly higher velocities than female patients on HGST and VGST (p = 0.02, p = 0.01). CONCLUSIONS The present study details the use of GST in patients with concussion and demonstrates an association with common outcome measures in vestibular rehabilitation. Results indicate that patients who achieved higher velocities on GST perceived lower handicap due to dizziness and had higher confidence in their balance. GST may be a relevant test of VOR in this population, as it is a more functional test of the VOR required for sports. Future work is needed to further evaluate the role of GST in concussion management.

Effectiveness of Vestibular Rehabilitation Therapy for Treatment of Concussed Adolescents With Persistent Symptoms of Dizziness and Imbalance. J Sport Rehabil 2018; 27:485-490.

Abstract
Context:Adolescents who suffer sport concussion typically respond to a prescription of cognitive and physical rest in the acute phases of healing; however, some adolescents do not respond to rest alone. Dizziness, unsteadiness, and imbalance are impairments, which may linger longer than 30 days, leading to a diagnosis of postconcussion syndrome (PCS). Vestibular assessment and therapy may benefit adolescents suffering from these persistent symptoms.Clinical Question:Does vestibular rehabilitation therapy (VRT) rather than continued prescription of rest (cognitive and physical) reduce recovery time and persistent symptoms of dizziness, unsteadiness, and imbalance in adolescents (12–18 y) who suffer PCS following a sports-related concussion?Summary of Key Findings:All 4 studies selected included adolescents suffering from PCS, specifically continued dizziness, unsteadiness, and imbalance. VRT was an effective intervention for this population. Adolescents presenting with this cluster of symptoms may also demonstrate verbal and visual memory loss linked to changes in the vestibular system postconcussion. Improved screening tools can help better understand vestibular system changes, identify adolescents who may benefit from VRT sooner, and decrease long-term impairments.Clinical Bottom Line:Moderate evidence supports that adolescents who suffer from persistent symptoms of dizziness, unsteadiness, and imbalance following sport concussion should be evaluated more specifically and earlier for vestibular dysfunction and can benefit from participation in individualized VRT. Early evaluation and treatment may result in a reduction of time lost from sport as well as a return to their premorbid condition. For these adolescents, VRT may be more beneficial than continued physical and cognitive rest when an adolescent’s symptoms last longer than 30 days.Strength of Recommendation:Grade B evidence exists to support that VRT is more effective than continued cognitive and physical rest in reducing persistent symptoms of dizziness, unsteadiness, and imbalance in adolescents who suffer PCS.

Abstract
Turning is common in daily activity and requires rapid, coordinated reorientation of the head, trunk, and pelvis toward the new direction of travel. Yet, turning gait has not been well explored in populations with mild traumatic brain injury (mTBI) who may alter their turning behavior according to self-perceived symptoms or motor dysfunction. The purpose of this study was to examine turning velocities and coordination in adults with chronic mTBI (>3 months post-injury and still reporting balance complaints) during a task simulating everyday ambulation. We hypothesized that individuals with chronic mTBI would reduce their angular velocity when turning and increase the variability of head-pelvis coordination compared with controls, and that the reduction in velocity and increased variability would be associated with their self-reported symptom score. Forty-two adults (14 chronic mTBI, 28 controls) completed the Neurobehavioral Symptom Inventory before walking 12 laps around a marked course containing two 45-degree turns, four 90-degree turns, and two 135-degree turns. Inertial sensors collected angular velocities of the head and pelvis. After adjusting for covariates, participants with chronic mTBI had significantly slower lap times and peak angular velocities of the pelvis (p < 0.01) compared with the control group. The peak velocity timing (PVT) between peak velocities of the head and pelvis, and the variability of that timing was significantly greater in participants with chronic mTBI (p < 0.01). Within the chronic mTBI group, somatosensory symptoms were associated with slower angular velocities of the head and pelvis (p = 0.03) and increased PVT variability (p < 0.01). The results suggest individuals with chronic mTBI with worse somatic symptoms have impaired head stabilization during turning in situations similar to everyday life. These results encourage future research on turning gait to examine the causal relationship between symptoms and daily locomotor function in adults with chronic mTBI.

Abstract
BACKGROUND The search for reliable and valid signs and symptoms of mild traumatic brain injury (mTBI), commonly synonymous with concussion, has lead to a growing body of evidence that individuals with long-lasting, unremitting impairments often experience visual and vestibular symptoms, such as dizziness, postural and gait disturbances. OBJECTIVE Investigate the role of visual-vestibular processing deficits following concussion. METHODS A number of clinically accepted vestibular, oculomotor, and balance assessments as well as a novel virtual reality (VR)-based balance assessment device were used to assess adults with post-acute concussion (n = 14) in comparison to a healthy age-matched cohort (n = 58). RESULTS Significant between-group differences were found with the VR-based balance device (p = 0.001), with dynamic visual motion emerging as the most discriminating balance condition. The symptom reports collected after performing the oculomotor and vestibular tests: rapid alternating horizontal eye saccades, optokinetic stimulation, and gaze stabilization, were all sensitive to health status (p < 0.05), despite the absence of oculomotor abnormalities being observed, except for near-point convergence. The BESS, King-Devick, and Dynamic Visual Acuity tests did not detect between-group differences. CONCLUSION Postural and visual-vestibular tasks most closely linked to spatial and self-motion perception had the greatest discriminatory outcomes. The current findings suggest that mesencephalic and parieto-occipital centers and pathways may be involved in concussion.

Abstract
Aims To develop and validate the Pediatric Visually Induced Dizziness Questionnaire (PVID) and quantify the presence and severity of visually induced dizziness (ViD), i.e., symptoms induced by visual motion stimuli including crowds and scrolling computer screens in children. Methods 169 healthy (female n = 89; recruited from mainstream schools, London, UK) and 114 children with a primary migraine, concussion, or vestibular disorder diagnosis (female n = 62), aged 6–17 years, were included. Children with primary migraine were recruited from mainstream schools while children with concussion or vestibular disorder were recruited from tertiary balance centers in London, UK, and Pittsburgh, PA, USA. Children completed the PVID, which assesses the frequency of dizziness and unsteadiness experienced in specific environmental situations, and Strength and Difficulties Questionnaire (SDQ), a brief behavioral screening instrument. Results The PVID showed high internal consistency (11 items; α = 0.90). A significant between-group difference was noted with higher (i.e., worse) PVID scores for patients vs. healthy participants (U = 2,436.5, z = −10.719, p < 0.001); a significant difference was noted between individual patient groups [χ2(2) = 11.014, p = 0.004] but post hoc analysis showed no significant pairwise comparisons. The optimal cut-off score for discriminating between individuals with and without abnormal ViD levels was 0.45 out of 3 (sensitivity 83%, specificity 75%). Self-rated emotional (U = 2,730.0, z = −6.169) and hyperactivity (U = 3,445.0, z = −4.506) SDQ subscale as well as informant (U = 188.5, z = −3.916) and self-rated (U = 3,178.5, z = −5.083) total scores were significantly worse for patients compared to healthy participants (p < 0.001). Conclusion ViD is common in children with a primary concussion, migraine, or vestibular diagnosis. The PVID is a valid measure for identifying the presence of ViD in children and should be used to identify and quantify these symptoms, which require specific management incorporating exposure to optokinetic stimuli.

Abstract
PURPOSE Academic difficulty is reported in children with prolonged post-concussive symptoms. Despite growing evidence that vestibular-ocular and vision-specific dysfunction are common in children after concussion, vision is rarely mentioned in return-to-learn protocols. The purpose of this project was to evaluate a cohort of children with prolonged post-concussive symptoms to determine if vision symptoms are associated with those reporting academic difficulty. METHODS Data were obtained from the Children's of Alabama Concussion Clinic REDCap dataset from the period January 2007 to October 2013. From this dataset of 1033 concussion events, a cohort of 276 children aged 5 to 18 years with three or more concussion-related symptoms present for 10 days or more was identified. A cross-sectional cohort study was undertaken to evaluate the association of concussion symptoms, SCAT2 scores, and demographic and concussion severity markers to reported educational difficulty among children with prolonged post-concussive symptoms. Univariate and multivariate logistic regression techniques were used to model the association of reported educational difficulty to self-reported vision abnormalities. RESULTS Mean age was 13.8 years. Median time since the concussive event was 21 days, with 33% (95/276) reporting their concussion more than 30 days before data collection. Academic difficulty was reported by 29% (79/270) and vision abnormalities in 46% (128/274). After model reduction, vision symptoms (OR 2.17, 95% CI 1.02, 4.62), hearing disturbance (OR 2.39, 95% CI 1.06, 5.36), and concentration difficulty (OR 21.62, 95% CI 9.50, 44.47) remained associated with academic difficulty. For those with symptoms 30 days or more after concussion, only vision (OR 3.15, 95% CI 1.06, 9.38) and concentration difficulty (OR 15.33, 95% CI 4.99, 47.05) remained statistically significant. CONCLUSIONS Vision problems were commonly reported in children with concussions and were independently associated with those reporting academic difficulty. Comprehensive vision assessment should be considered in children reporting academic difficulty and in the development of return-to-learn protocols.

Abstract
BACKGROUND The immediate post concussion assessment and cognitive testing (ImPACT) is the most widely used concussion assessment tool. Despite its popularity, it is unclear if validation studies for the ImPACT test covered all aspects of validity to support its widespread use in research and clinical practice. OBJECTIVE The purpose of this report is to review literature surrounding the validity and the utility of the ImPACT test. DATA SOURCES AND APPRAISAL A systematic review of relevant studies in PubMed, CINAHL, and PsycINFO was carried out. Studies were evaluated using the STROBE (strengthening the reporting of observational studies in epidemiology) or the STARD (standards for reporting of diagnostic accuracy) criteria. RESULTS The literature search yielded 5968 studies. Sixty-nine studies met the inclusion criteria and were included in the qualitative review. Although the convergent validity of ImPACT was supported, evidence of discriminant and predictive validity, diagnostic accuracy and responsiveness was inconclusive. The utility of the ImPACT test after acute symptom resolution was sparse. The review found many factors influenced the validity and utility of ImPACT scores. CONCLUSION Clinicians must consider the benefit of ImPACT testing for their patients on a case-by-case scenario and must take the psychometric properties of the test into account when interpreting results.

Abstract
BACKGROUND One common component of concussion rehabilitation is a computerized cognitive test free of concomitant physical demands. Healthcare professionals may be able to provide more patient-centered care after a diagnosed concussion if specific areas of impairment are identified and treated, such as the physical aspect of neurocognitive function. Hypothesis/Purpose: To evaluate the test-retest reliability of a unique combination of neurocognitive assessment tools currently utilized in concussion assessments into one single, inclusive instrument that measures both neurocognitive function and physical capability. STUDY DESIGN Original research - diagnostic tests. METHODS Fourteen individuals (nine males, age: 29 + 17.9, five females, age: 46.0 ± 21.5 years) either with normal cognitive function (NBI) without history of a health event (e.g. cerebral vascular accident/stroke, mTBI) that resulted in brain injury within one year of the study, or who had suffered a health event that has resulted in a medically documented brain injury (BI) participated in the study. Participants completed the full hybrid assessment instrument for a baseline test, then completed a follow-up test using the same instrument within 72-96 hours of baseline. Test-retest reliability was measured using Pearson product-moment correlations of the first and second testing sessions, and a two-way ANOVA (group between factor: NBI and BI and time within factor: session 1 and session 2) was performed on the summative scores to determine differences between each group. RESULTS Test-retest reliability was strong and statistical significant for both the NBI (r = .858, p = .014) and the BI (r = .967, p = .033) groups. There was a significant difference between summative scores for the NBI and BI groups (F1,20 = 42.325, p < .0001). CONCLUSION The newly created Comprehensive Instrument for Evaluating Mild Traumatic Brain Injury (CIEMTBI) demonstrates good test-retest reliability and was able to discriminate the results between individuals in the NBI and BI groups. Further research, specifically with different samples, is needed to better determine the reliability and diagnostic accuracy of the instrument. LEVEL OF EVIDENCE 2c.

Abstract
CONTEXT Comprehensive, multidomain assessment is the standard of care after sport-related concussion. However, the relationship between performance on sideline concussion-assessment tools and in-office computerized neurocognitive testing has received little attention, and the prognostic utility of sideline measures is unknown. OBJECTIVE To evaluate concurrent impairment on commonly used concussion measures 24 to 48 hours postinjury while also determining the predictive utility of sideline measures on computerized neurocognitive testing in the acute to subacute recovery periods postinjury. DESIGN Case-control study. SETTING High school and collegiate athletics. PATIENTS OR OTHER PARTICIPANTS A total of 125 high school and college-aged athletes (85 males, 40 females) 14 to 23 (16.8 ± 2.21) years old. MAIN OUTCOME MEASURE(S) Participants were administered sideline concussion-assessment measures (ie, Immediate Post-Concussion Assessment and Cognitive Testing [ImPACT], Standardized Assessment of Concussion [SAC], and Balance Error Scoring System [BESS]) 24 to 48 hours postinjury and completed ImPACT and the Post-Concussion Symptom Scale 5 to 7 and 10 to 14 days postinjury. Outcome measures were the ImPACT composite (verbal memory, visual memory, reaction time, visual-motor speed), SAC, and BESS scores and total symptom score on the Post-Concussion Symptom Scale. RESULTS Participants demonstrated heterogeneous patterns of impairment on measures 24 to 48 hours postinjury, with the most common pattern being impairment on ImPACT and the SAC. Performance on the SAC and BESS at 24 to 48 hours after injury did not distinguish between those with and those without impairment on ImPACT at 5 to 7 days postinjury (χ2 = 5.076, P = .079) or 10 to 14 days postinjury (χ2 = 2.04, P = .361). CONCLUSIONS More than 90% of athletes were impaired on at least 1 sideline or neurocognitive measure 24 to 48 hours after sport-related concussion. Although sideline measures are useful for concussion diagnosis, they are not suitable for prognostication of impairment or the presence of symptoms 1 to 2 weeks postinjury.

Abstract
BACKGROUND A concussion is a complex pathophysiologic process that is induced by biomechanical forces and affects the brain. Cervical injuries and concussion can share similar mechanisms and nearly identical symptoms or causes. Therefore, symptoms or causes alone may be insufficient to differentiate between patients with a concussion and patients with cervical injuries. OBJECTIVE To demonstrate the homogeneous causes and symptoms observed in patients with a concussion and patients with cervical injury and to provide information on clinical tests that can differentiate cervical injury from pathologic conditions of vestibular or central origin. SUMMARY Given that concussion and cervical injury share similar causes and symptoms, this information alone may be insufficient to diagnose a concussion. Clinical assessments, such as the cervical joint-reposition error test, smooth-pursuit neck-torsion test, head-neck differentiation test, cervical flexion-rotation test, and physical examination of the cervical spine, can be performed after a head and neck pathomechanical event to identify the presence of cervical injury. Differentiating between a concussion and cervical injury is clinically vital for timely and appropriate evidence-based treatment. CONCLUSIONS Specific clinical tests should be used after a head and neck pathomechanical event to differentiate between symptoms due to a concussion and cervical injury. Continued research on the clinical utility of the 5 identified cervicogenic tests is also recommended.
