Musculoskelet Sci Pract 2022; 57:102490. [PMID: 34847469 DOI: 10.1016/j.msksp.2021.102490] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 10/11/2021] [Accepted: 11/20/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND Clinically relevant scores of neck disability have been observed in adults post mild traumatic brain injury (mTBI), even in those who initially report to be recovered. Potentially cervical musculoskeletal and/or cervical sensorimotor impairments may underlie these persistent symptoms post mTBI. OBJECTIVE To determine whether cervical impairments exist beyond expected recovery times following concussion compared to healthy controls (HC). STUDY DESIGN Observational cohort study. METHODS Participants aged 18-60 years consisting of 39 HC, and 72 individuals, 4 weeks to 6 months post mTBI of which 35 considered themselves asymptomatic (Asymp), and 37 symptomatic (Symp). Cervical outcome measures included range and velocity of motion, flexor muscle endurance, presence of at least one dysfunctional cervical joint, joint position error -neutral and torsion, movement accuracy, smooth pursuit neck torsion test (SPNT) and balance. RESULTS Individuals in the Symp mTBI group demonstrated significantly reduced: flexion and rotation range, rotation velocity, flexor endurance and movement accuracy as well as increased postural sway and a higher percentage had positive cervical joint dysfunction (p < 0.01]. The mTBI group who considered themselves recovered (Asymp)demonstrated significantly lower rotation range, flexor endurance, and a higher percentage had positive cervical joint dysfunction and positive SPNT (p < 0.05) compared to HCs. CONCLUSION Individuals reporting symptoms post mTBI demonstrated cervical spine musculoskeletal and sensorimotor impairments beyond expected recovery times. Those not reporting symptoms had fewer but some cervical impairments. The need for a comprehensive neck assessment should be considered, perhaps even in those not reporting symptoms.

Sensorimotor system changes in adolescent rugby players post-concussion: A prospective investigation from the subacute period through to return-to-sport. Musculoskelet Sci Pract 2022; 57:102492. [PMID: 34922255 DOI: 10.1016/j.msksp.2021.102492] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 07/26/2021] [Accepted: 12/07/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND The pathophysiology of concussion is complex. Altered sensorimotor function post-concussion may contribute to the wide range of symptoms and impairments reported. There is currently limited evidence documenting changes in sensorimotor function during the recovery period. The aim of this study was to investigate the effect of concussion on the sensorimotor system in adolescents post-concussion using a multifaceted approach. STUDY DESIGN Prospective nested case-control study. METHODS A total of 285 male adolescent rugby players underwent assessment of sensorimotor function during preseason. Players who sustained a concussion during the season and control players, matched for age and playing position, were assessed in the subacute period (3-5 days) and after return-to-sport (3 weeks). Tests of sensorimotor function included balance, cervical spine and vestibulo-ocular function, and measurement of the size and contraction of lumbopelvic muscles (ultrasound imaging). RESULTS Twenty-three players (8%) sustained a concussion. Of these, 20 players were assessed during the subacute period and 17 players following return-to-sport. The prevalence of vestibulo-ocular dysfunction increased from 38.9% to 72.2% during the subacute period and dysfunction was present in 83.3% of players after return-to-sport (p = 0.01). Changes in lumbar multifidus muscle size (p = 0.002) and thickness (p = 0.05) at the L5 vertebral level were observed. No statistically significant changes in balance, cervical spine proprioception, or contraction of lumbopelvic muscles were found (p > 0.05). CONCLUSION Changes in sensorimotor function were observed in the subacute period post-concussion, with some persisting after return-to-sport. Using symptom-based criteria for return-to-sport may not adequately reflect the sequelae of concussion on the sensorimotor system.

Abstract
Objective To identify and synthesise research evidence regarding psychometric properties and clinical utility of the Buffalo Concussion Treadmill Test (BCTT) and Buffalo Concussion Bike Test (BCBT) for use with patients with acute concussion, post-concussion syndrome (PCS) or physiological post-concussion disorder (PPCD). Data sources ProQuest (ProQuest Central), PEDro, Medline (Ovid), Emcare (Ovid), EBSCOhost (Health collection) and Google Scholar, searched September 8th-12th, 2020. Study selection Two authors independently selected studies that met eligibility criteria. Studies were selected if they were original research of any design, that investigated the properties of the testing protocols in either concussed or uninjured participants. Articles not published in English, that were not original research or that used significantly different testing protocols were excluded. The search yielded 250 articles, 11 of which were eligible and included in this review. Data extraction Included studies were critically appraised independently by two authors, using the Mixed Methods Appraisal Tool (MMAT). Data relating to study characteristics and key findings were extracted from the studies, documented in tables, and used to inform a critical narrative synthesis of findings. Data synthesis To provide recommendations relating to each aim of the review, a strength of evidence scoring system was used. Available evidence supported use of the BCTT, with strong evidence supporting the safety and construct validity of the test and moderate evidence supporting its prognostic value. There has been very limited research investigating use of the BCBT. Conclusion The findings support a recommendation for use of the BCTT in clinical settings for management of acute concussion, PCS and PPCD. There is limited evidence available for the BCBT. Additional studies are needed of both tests to further establish their clinical value.

Abstract
OBJECTIVE To identify whether adults 4 weeks to 6 months post mild traumatic brain injury (mTBI) have sensorimotor impairments when compared to healthy controls. A secondary aim was to determine if impairments were evident irrespective of participant perceived absence of symptoms. DESIGN Observational cohort study SETTING: Tertiary University and Hospital PARTICIPANTS: Participants included 113 individuals aged 18 to 60 years consisting of 39 controls with no prior concussion history, and 74 individuals, 4 weeks to 6 months post mTBI of which 35 considered themselves asymptomatic (Asymp), and 37 symptomatic (Symp). MAIN OUTCOME MEASURES Assessments of oculomotor, vestibulo-ocular reflex (VOR) control, balance, single and dual task tandem walk (TTW-S, TTW-D) and vestibular positional testing. RESULTS Poorer balance and tandem walk performance, and a higher frequency of positive oculomotor, VOR and vestibular positional tests were evident in the mTBI group compared to controls. In particular ≥ 2 positive oculomotor findings were evident in 53.7% of the participants with mTBI compared to 10.8 % of controls. The mTBI group who considered themselves recovered (Asymp) demonstrated significantly increased TWT-D time, and a higher proportion 53% had ≥ 2 positive oculomotor tests compared to controls. CONCLUSION Persistent sensorimotor impairments, particularly evidenced by disturbed oculomotor function and deficits in dual task tandem walking were identified among adults 4 weeks to 6 months post mTBI. These disturbances were evident regardless of whether ongoing symptoms were reported. The findings support recommendations for routine clinical assessment of sensorimotor function post mTBI with implications for injury prevention.

Abstract
PURPOSE OF REVIEW Concussion produces a variety of signs and symptoms. Most patients recover within 2-4 weeks, but a significant minority experiences persistent post-concussive symptoms (PPCS), some of which may be from associated cervical or persistent neurologic sub-system (e.g., vestibular) dysfunction. This review provides evidence-based information for a pertinent history and physical examination of patients with concussion. RECENT FINDINGS The differential diagnosis of PPCS is based on the mechanism of injury, a thorough medical history and concussion-pertinent neurological and cervical physical examinations. The concussion physical examination focuses on elements of autonomic function, oculomotor and vestibular function, and the cervical spine. Abnormalities identified on physical examination can inform specific forms of rehabilitation to help speed recovery. Emerging data show that there are specific symptom generators after concussion that can be identified by a thorough history, a pertinent physical examination, and adjunct tests when indicated.

Abstract
PURPOSE OF REVIEW Concussion is a complex injury that may present as a variety of clinical profiles, which can overlap and reinforce one another. This review summarizes the medical management of patients with concussion and persistent post-concussive symptoms (PPCS). RECENT FINDINGS Management of concussion and PPCS relies on identifying underlying symptom generators. Treatment options include sub-symptom threshold aerobic exercise, cervical physical therapy, vestibular therapy, vision therapy, cognitive rehabilitation, cognitive behavioral therapy, pharmacological management, or a combination of treatments. Evidence-based treatments have emerged to treat post-concussion symptom generators for sport-related concussion and for patients with PPCS.

Abstract
Objective clinical tools, including cognitive-motor integration (CMI) tasks, have the potential to improve concussion rehabilitation by helping to determine whether or not a concussion has occurred. In order to be useful, however, an individual must put forth their best effort. In this study, we have proposed a novel method to detect the difference in cortical activity between best effort (no-sabotage) and willful under-performance (sabotage) using a deep learning (DL) approach on the electroencephalogram (EEG) signals. The EEG signals from a wearable four-channel headband were acquired during a CMI task. Each participant completed sabotage and no-sabotage conditions in random order. A multi-channel convolutional neural network with long short term memory (CNN-LSTM) model with self-attention has been used to perform the time-series classification into sabotage and no-sabotage, by transforming the time-series into two-dimensional (2D) image-based scalogram representations. This approach allows the inspection of frequency-based, and temporal features of EEG, and the use of a multi-channel model facilitates in capturing correlation and causality between different EEG channels. By treating the 2D scalogram as an image, we show that the trained CNN-LSTM classifier based on automated visual analysis can achieve high levels of discrimination and an overall accuracy of 98.71% in case of intra-subject classification, as well as low false-positive rates. The average intra-subject accuracy obtained was 92.8%, and the average inter-subject accuracy was 86.15%. These results indicate that our proposed model performed well on the data of all subjects. We also compare the scalogram-based results with the results that we obtained by using raw time-series, showing that scalogram-based gave better performance. Our method can be applied in clinical applications such as baseline testing, assessing the current state of injury and recovery tracking and industrial applications like monitoring performance deterioration in workplaces.

Abstract
OBJECTIVE To describe individual long-term outcomes of people with persistent symptoms following a concussion who received neck treatment as part of multidisciplinary concussion care. A secondary objective is to report on how participants describe the outcomes of neck treatmentMethods: Long-term follow-up for a subgroup of participants in a prospective case series (n = 11). Data were collected at initial assessment, completion of neck treatment, 6 and 12 months including standard questionnaires (Rivermead post-concussion symptoms questionnaire, neck disability index, dizziness handicap inventory); patient-reported measures of headache, dizziness and neck pain and participant descriptions of the effects of neck treatmentResults: Grouped measures of post-concussion symptoms were further improved or sustained at 6 and 12 months. Ten of the 11 participants reported neck treatment as a beneficial part of their care and described the effects on the neck, multiple symptoms and their overall recovery. However, seven participants experienced recurrent headache, neck pain or dizziness at 6- or 12-month follow-up. CONCLUSION Long-term follow-up of individuals receiving neck treatment shows improvement across a range of patient reported outcomes, yet highlights frequent recurrence of symptoms. Neck treatment can play a valuable role in people's recovery that extends beyond local effects on the neck.

Abstract
CONTEXT Recovery protocols for treatment of sports concussion have received widespread adoption across the country. While stages of recovery and treatment are relatively clearly defined, there remains variability in implementation of specific recommendations, particularly regarding activities that constitute rest during stages calling for limitations on activity participation. Specific recommendations being employed by practitioners have not been previously assessed. In an aim to document current concussion management practices in the field, athletic trainers were surveyed regarding how activities that may constitute rest are utilized and defined. DESIGN The study was based on a cross-sectional vignette-based survey. METHODS The sample used was a geographically representative convenience sample of United States-based high school athletic trainers. E-mails were sent to 2146 potential survey respondents yielding a final sample of 226 athletic trainers. Data were gathered for questions concerning recommendations for follow-up care and rest based on provided vignettes, factors considered when developing recommendations, and differences in recommendations associated with varying symptom presentations. The percentage of practitioners that would utilize each potential recommendation was used to characterize results. RESULTS Participants demonstrated consensus on the importance of physical and cognitive rest as well as school accommodations (all greater than 97% endorsement). Greater variability was present for recommendations regarding pain medication for headache, repeating baseline cognitive testing, and engaging in subsymptom threshold activities. Recommendations for attending but not participating in games and practice yielded conflicting information. CONCLUSIONS Responses indicated general consensus regarding factors considered when making recommendations. There was also consensus regarding general recommendations for activity limitation following recovery with almost all participants strongly recommending cognitive and physical rest, in accordance with consensus guidelines. However, substantial differences were found for specific activities that should be limited or encouraged following youth concussion. Further research concerning the relationship between community and social interaction and clinical outcomes after concussion is warranted.

Abstract
A concussion occurs when a direct or indirect force is transmitted to the brain, causing a change in brain function. Given that approximately half the brain circuits are involved in vision and the control of eye movements, a concussion frequently results in visual symptoms. Ophthalmic abnormalities are helpful in the assessment of acute concussion, identified by rapid automized naming tasks and eye movement assessments. In particular, convergence, eye-tracking and the vestibular-ocular motor screening tool may be used. For patients suffering from post-concussion syndrome more than 3 months from the original injury, abnormalities may be found in convergence, accommodation and smooth pursuit. Orthoptic exercises are useful rehabilitation tools to allow patients to return to school, work and recreation. This article provides a brief overview of concussion as it relates to vision and ophthalmic practice.

Abstract
OBJECTIVES To evaluate the clinical utility of tactile somatosensory assessments to assist clinicians in diagnosing sport-related mild traumatic brain injury (SR-mTBI), classifying recovery trajectory based on performance at initial clinical assessment, and determining if neurophysiological recovery coincided with clinical recovery. RESEARCH DESIGN Prospective cohort study with normative controls. METHODS At admission (n = 79) and discharge (n = 45/79), SR-mTBI patients completed the SCAT-5 symptom scale, along with the following three components from the Cortical Metrics Brain Gauge somatosensory assessment (BG-SA): temporal order judgement (TOJ), TOJ with confounding condition (TOJc), and duration discrimination (DUR). To assist SR-mTBI diagnosis on admission, BG-SA performance was used in logistic regression to discriminate cases belonging to the SR-mTBI sample or a healthy reference sample (pooled BG-SA data for healthy participants in previous studies). Decision trees evaluated how accurately BG-SA performance classified SR-mTBI recovery trajectories. RESULTS BG-SA TOJ, TOJc, and DUR poorly discriminated between cases belonging to the SR-mTBI sample or a healthy reference sample (0.54-0.70 AUC, 47.46-64.71 PPV, 48.48-61.11 NPV). The BG-SA evaluated did not accurately classify SR-mTBI recovery trajectories (> 14-day resolution 48%, ≤14-day resolution 54%, lost to referral/follow-up 45%). Mann-Whitney U tests revealed differences in BG-SA TOJc performance between SR-mTBI participants and the healthy reference sample at initial clinical assessment and at clinical recovery (p < 0.05). CONCLUSIONS BG-SA TOJ, TOJc, and DUR appear to have limited clinical utility to assist clinicians with diagnosing SR-mTBI or predicting recovery trajectories under ecologically valid conditions. Neurophysiological abnormalities persisted beyond clinical recovery given abnormal BG-SA TOJc performance observed when SR-mTBI patients achieved clinical recovery.

Abstract
Mild traumatic brain injury accounts for an estimated 4.8 million cases of pediatric traumatic brain injuries worldwide every year. In the United States, 70% of mild traumatic brain injury cases are due to sports and recreational injuries. Early diagnosis, especially in active children, is critical to preventing recurrent injuries. Management is guided by graded protocols for returning to school and activity. Ninety percent of children recover within 1 month of injury. Promising research has shown that early referral to specialty concussion care and multidisciplinary treatment with physical and occupational therapy may shorten recovery time and improve neurologic outcomes.

Condition-specific health-related quality of life amongst amateur athletes six months and one-year following sport-related concussion: A prospective, follow-up. Phys Ther Sport 2021; 51:71-78. [PMID: 34273667 DOI: 10.1016/j.ptsp.2021.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 06/26/2021] [Accepted: 06/29/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To prospectively investigate the condition-specific health-related quality of life (HRQoL) of athletes six months and one-year following sport-related concussion. DESIGN Prospective, longitudinal study. SETTING Clinical research centre at university school of public health. PARTICIPANTS Amateur athletes who were diagnosed with sport-related concussion within one-week after presenting to a hospital emergency department were recruited along with sex-, age-, and activity-matched, non-concussed, control athletes. Concussion and control participants were assessed six months and one-year following sport-related concussion and study enrolment, respectively. MAIN OUTCOME MEASURES Participants completed the Post-Concussion Symptom Scale and five condition-specific HRQoL patient-reported outcome measures - Headache Impact Test-6, Fatigue Severity Scale, Neck Disability Index, Generalised Anxiety Disorder-7, and Dizziness Handicap Inventory. We performed Frequentist and Bayesian mixed-design analyses of variance to compare the concussion group and control group at both assessments and quantify whether there was greater evidence in favour of the null hypothesis compared with the alternative hypothesis. RESULTS At six-month and one-year assessments, the concussion group (n = 47; male = 72%; mean (SD) age = 22.68 (5.07)) and the control group (n = 47; male = 72%; mean (SD) age = 23.81 (4.60)) reported similar clinical symptom severity scores and condition-specific HRQoL. The proportion of athletes in the concussion group with clinically-impaired scores was similar to the proportion of non-concussed athletes with clinically-impaired scores. At six-month and one-year assessments, there was moderate-to-very strong evidence that there was no difference between concussion and control participants' perceptions of the effects of headache, fatigue, neck pain, anxiety, and dizziness on HRQoL. CONCLUSION There was moderate-to-very strong evidence in favour of no difference between the concussion and control groups on symptom severity scores and condition-specific HRQoL patient-reported outcome measures at six-month and one-year assessments. These results suggest that condition-specific HRQoL returns to the levels of non-concussed individuals within six months following sport-related concussion.

Abstract
BACKGROUND An estimated 45% of concussions are reported to be related to motor vehicle collisions (MVC). However, limited research exists involving the treatment of MVC-related concussion, especially when combined with whiplash-associated disorders (WAD). Purpose: The purpose of this case series is to examine the patient response to an irritability-based approach to the physiological, cervical, and vestibulo-ocular trajectories in patients with diagnosed concussion and WAD disorder following an MVC. Case Description: Three patients clinically diagnosed by a neurologist with WAD and concussion following a rear-end MVC were evaluated and treated in an outpatient physical therapy setting. Each individual was progressed through an irritability-based treatment approach based on individual symptom presentation. Outcomes: Following therapy, 2 of 3 patients reported full resolution of subjective symptoms with a negative Vestibular Oculo-motor Screening All patients exceeded their predicted goals based on Focus on Therapeutic Outcomes score. CONCLUSION This case series demonstrated successful treatment of all three individuals with concussion and concurrent WAD. Two of three individuals demonstrated full resolution of subjective symptoms and objective impairments at the end of treatment. Further research is warranted into the effectiveness of a multi-factorial approach to address the highly variable symptom profile of individuals with concussion and WAD.

Abstract
PURPOSE To examine the safety of high-level mobility (HLM) prescription in the early sub-acute phase of recovery following moderate-to-extremely severe traumatic brain injury (TBI) with specific focus on provocation of concussion-like symptoms. DESIGN Systematic review. PROSPERO ID: CRD42017069369. MAIN MEASURES Extracted data included study design, brain injury severity, time to commence HLM, type of HLM, physiological and symptom monitoring, and rate of adverse events. RESULTS Nineteen studies were included in the review. Fifteen studies included participants who commenced HLM within 6 weeks of injury, with the earliest time to commencement being 3 days. Overall, adverse events and symptom monitoring were poorly reported. A total of six adverse events were reported across three studies. One of the six adverse events was a concussion-like symptom. No falls were reported. No studies monitored concussion-like symptom provocation in direct relation to HLM. CONCLUSION A safe timeframe for return to HLM after moderate-to-extremely severe TBI could not be determined due to insufficient reporting of symptom monitoring and adverse events. Further research into the safety of HLM in the early sub-acute rehabilitative stage after moderate-to-extremely severe TBI is required in order to better understand potential sequelae in this population.IMPLICATIONS FOR REHABILITATIONHigh-level mobility assessment and training is commonly reported in the early sub-acute phase of recovery following moderate-to-extremely severe traumatic brain injury.There is no consensus on a safe timeframe to commence high-level mobility assessment or training after moderate-to-extremely severe traumatic brain injury.High-level mobility assessment and training appears to be safe in the early sub-acute phase following moderate-to-extremely severe traumatic brain injury, however, adverse events and symptoms are poorly reported.Clinicians should continue to proceed with caution when assessing and prescribing high-level mobility for patients with moderate-to-extremely severe traumatic brain injury in the early sub-acute phase of recovery and monitor for risks such as falls and exacerbation of concussion-like symptoms.

Abstract
Introduction: Research indicates Sports-Related Concussion (SRC) impairs Vestibular-Ocular-Motor (VOM) function. The aim was to explore if VOM impairment correlates with longer Return To Play (RTP), symptom burden, neurocognitive performance and academic capability.Participants: 40 (61.4% male) Loughborough University, UK, rugby union student-athletes who sustained 42 SRCs.Methods: Student-athletes completed an assessment battery during pre-season (baseline), 2, 4, 8 and 14 days post-SRC and prior to RTP and were managed according to the rugby Football Union' community pathway.Outcome measures: Vestibular Ocular-Motor Screening (VOMS), Immediate Post-Concussion Assessment and Cognitive Test, Post-Concussion Symptom Scale, Perceived Academic Impairment Tool questionnaire and percentage of academic activities specifically missed due to SRC.Results: VOMS scores were significantly (p < 0.005) greater than baseline at all time points except RTP. Presence of VOM dysfunction at 14 days post-SRC significantly correlated with a longer RTP, greater symptom burden and increased odds ratio at 2, 4 and 8 days and academic time loss at 2, 4 and 8 days post-SRC.Conclusion: VOM impairment is associated with an increased symptom burden and impaired academic capability, and a longer time to RTP when present at 14 days post-SRC.

Abstract
BACKGROUND Patients with cervicogenic symptoms following a concussion have shown a disproportionate rate of delayed symptom resolution. However, the prevalence of cervicogenic symptoms in the acute stages following a concussion and the percentage of those patients who continue on to suffer delayed symptom resolution is poorly described in the literature. OBJECTIVES To provide a comprehensive report on the clinical prevalence, diagnostic methods, and potential treatment options for cervicogenic symptoms that are elicited during acute and chronic phases following a concussion. METHODS Electronic searches were conducted in PubMed, SPORTDiscus, ICL, CINAHL and PEDro, from inception to May 2020, to identify original research articles on concussion involving cervicogenic symptoms. We assessed each included article for risk of bias, methodological quality, level of evidence and evidence quality. The articles were categorized into three topics: (1) prevalence of post-concussion cervicogenic symptoms; (2) diagnostic testing for cervicogenic symptoms, and (3) treatment techniques for cervicogenic symptoms. RESULTS The initial review resulted in 1443 abstracts, of which 103 abstracts met the inclusion criteria of our research. After the review of full text, 80 articles were excluded, which resulted in a total of 23 articles for this systematic review. Prevalence of cervicogenic symptoms in the acute stages ranged from 7 to 69% and increased to 90% in patients experiencing persistent post-concussive symptoms. Neck pain at initial evaluation increased risk of developing persistent post-concussive symptoms (PPCS) by 2.58-6.38 times. Patient-reported outcome measures (e.g., Neck Disability Index, Dizziness Handicap Inventory, and Rivermead Post-Concussion Questionnaire) can identify patients with cervicogenic symptoms that should be further differentiated by clinical testing. Lastly, treatment using graded cervical manual therapy has shown to reduce time to symptom resolution and medical clearance. CONCLUSIONS Cervicogenic symptoms are prevalent in the acute and chronic stages following concussion, which if not diagnosed appropriately increase the likelihood of PPCS. Several clinical tests are available to help differentiate cervicogenic symptoms; however, lack of awareness and hesitation by practitioners limits their use. More randomized controlled trials are necessary to evaluate the effectiveness of cervical specific treatment programs for PPCS.

Abstract
CONTEXT Previous studies have demonstrated the effectiveness of osteopathic manipulative treatment (OMT) for various headache types, with limited evidence of its use for headaches related to mild traumatic brain injury (MTBI). No studies prior studies were found regarding OMT for headaches in patients with postconcussion syndrome (PCS), defined as symptom persistence for longer than 3 months after MTBI. OBJECTIVES To evaluate OMT for headaches in patients with PCS. METHODS A controlled pilot study was conducted of patients with PCS who presented to an outpatient interdisciplinary rehabilitation clinic; patients with symptoms lasting longer than 3 months were enrolled and randomly assigned to an OMT treatment group or a control group. Primary outcome measures were immediate change in headache scores according to a Visual Analog Scale (VAS) and change in the six item Headache Impact Test (HIT-6) between baseline and follow up visits. The participants in the control group completed the HIT-6 between baseline and follow up visits but did not receive OMT and did not complete the VAS. Mean immediate VAS score change for the treatment group and mean improvement in HIT-6 scores for both groups between baseline and follow up were analyzed for statistical significance. RESULTS A total of 26 patients were included in this study: 13 (50%) in the treatment group and 13 (50%) in the control group. Six patients (23.1%), three from each group, did not complete the study, so 10 subjects in each group were included in the final analysis. Statistically significant improvement in VAS scores was seen immediately after OMT in the treatment group (mean change, 2.1;p=0.002). Mean HIT-6 scores showed improvement in the treatment group compared with the control group, although the change was not statistically significant (p=0.15) from baseline to follow up visit. No adverse effects from treatments were noted. CONCLUSIONS Patients with headaches secondary to PCS showed immediate benefit in headache pain intensity after OMT. However, no sustained benefit was found on the follow up visit compared with the control group.

Abstract
PRIMARY OBJECTIVE - To discuss how the underlying neuroanatomy and neurobiology of five sport-related concussion (SRC) clinical profiles impacts assessment and treatment. RESEARCH DESIGN - Narrative review. METHODS AND PROCEDURES - Based on the current literature and clinical experience, arguments against the traditional SRC protocol and for a clinical profiles-based SRC protocol are made. MAIN OUTCOMES AND RESULTS - While the clinical profiles-based SRC protocol is widely used and accepted, there has been little published regarding the link to the underlying neuropathology. Our narrative review describes the five SRC clinical profiles: vestibular, ocular, mood, post-traumatic migraine, and cognitive/fatigue. For these profiles, the underlying neuroanatomy and neurobiology is outlined, as well as how that anatomy and biology impact the profiles' etiology, assessment, and treatment. The cervical and sleep modifiers are also briefly covered. CONCLUSIONS - Utilizing this model, clinicians are able to provide an individualized assessment, conceptualization, and treatment plan for SRC, leading to improved outcomes and clinical experiences for athletes.

Abstract
OBJECTIVES To identify which aspects of initial clinical assessment for sport-related mild traumatic brain injury (SR-mTBI) predict whether an athlete achieves symptom resolution within 14 days of the injury. RESEARCH DESIGN Retrospective cohort study using prospectively collected data. METHODS Clinical assessment data were collected from 568 patients diagnosed with SR-mTBI at a single medical clinic between February 2017 and December 2018. Demographic data, medical history, SCAT-5 testing, and physician notes were included in the data set. Data were processed and analysed to identify a shortlist of predictor variables to develop a logistic regression model to discriminate between SR-mTBI symptom resolution that occurred in ≤ 14-days or > 14-days. The data were randomly divided into model development and validation subsamples. The top 15 models were analysed to determine the predictor variables to be included in the final logistic regression model. The final model was then applied to the validation subsample. RESULTS Half of the athlete participants in this study experienced > 14-day symptom resolution. The final logistic regression model included sex, symptom reporting at initial assessment and presentation with a physiological predominant symptom cluster. The model accounted for 0.90 and 0.85 of the area under the curve and predicted recovery trajectory with 81% and 76% accuracy for the training and validation subsamples, respectively. CONCLUSIONS Being female, reporting a higher Positive Symptom Total at initial assessment, and being less likely to have a physiological predominant symptom cluster at initial assessment predicted > 14 versus ≤ 14-day SR-mTBI symptom resolution with a high level of accuracy.

Abstract
CONTEXT Despite evidence implicating cervicogenic symptoms in the development of persistent postconcussion symptoms, factors that influence utilization of cervical clinical tests to identify cervicogenic symptoms following concussion are poorly understood. OBJECTIVE Explore barriers to the utilization of cervical clinical testing in multifaceted concussion evaluation. DESIGN Cross-sectional. SETTING Online survey. PATIENTS OR OTHER PARTICIPANTS A total of 122 athletic trainers (AT) (age = 42.6 [6.4] y; female = 51.6%; 52% >10 y of clinical practice; 68% master's degree or greater; 35% treated a minimum of 15 concussions/y). MAIN OUTCOME MEASURE(S) Perceived importance, clinical experience, number of concussions treated, utilization of cervical clinical tests following nonspecific cervical pathology and following concussion, comfort with cervical treatment modalities following a concussion, and recommendation for cervical-specific therapy to treat persistent postconcussion symptoms. RESULTS Ordinal logistic regression revealed perceived importance had the strongest positive impact on AT's likelihood of high utilization of cervical clinical testing following concussion (95% CI, .17 to .99; P = .005), while clinical experience (95% CI, -.43 to .29; P = .71) and number of concussions treated/y (95% CI, -.21 to .31; P = .71) had no bearing. Moreover, low comfort with cervical treatments following a concussion (95% CI, -2.86 to -.26; P = .018) and low utilization of cervical clinical testing following nonspecific cervical pathology (95% CI, -7.01 to -3.39; P ≤ .001) had a strong positive impact on high utilization of cervical clinical testing following concussion. Two logistic regression models demonstrated how recommendations for cervical-specific therapy in persistent post-concussion symptom patients could be predicted based on (1) cervical test utilization and (2) perceptions and clinical experience with 79% and 78%, respectively. CONCLUSIONS Perceived importance played a major role in utilization of cervical clinical test following concussion. ATs who utilized common cervical treatments when dealing with non-concussive injuries were more likely to utilize those same treatments to treat comorbid cervical pathology following a concussion.

Abstract
BACKGROUND Persistent postconcussive symptoms (PCS) are poorly understood in children. Research has been limited by an assumption that children with concussion are a homogenous group. OBJECTIVE To identify (i) distinctive postconcussive recovery trajectories in children and (ii) injury-related and psychosocial factors associated with these trajectories. METHODS This study is part of a larger prospective, longitudinal study. Parents of 169 children (5-18 yr) reported their child's PCS over 3 mo following concussion. PCS above baseline levels formed the primary outcome. Injury-related, demographic, and preinjury information, and child and parent mental health were assessed for association with trajectory groups. Data were analyzed using group-based trajectory modeling, multinomial logistic regression, and chi-squared tests. RESULTS We identified 5 postconcussive recovery trajectories from acute to 3 mo postinjury. (1) Low Acute Recovered (26.6%): consistently low PCS; (2) Slow to Recover (13.6%): elevated symptoms gradually reducing; (3) High Acute Recovered (29.6%): initially elevated symptoms reducing quickly to baseline; (4) Moderate Persistent (18.3%): consistent, moderate levels of PCS; (5) Severe Persistent (11.8%): persisting high PCS. Higher levels of child internalizing behaviors and greater parental distress were associated with membership to the Severe Persistent group, relative to the Low Acute Recovered group. CONCLUSION This study indicates variability in postconcussive recovery according to 5 differential trajectories, with groups distinguished by the number of reported symptoms, levels of child internalizing behavior problems, and parental psychological distress. Identification of differential recovery trajectories may allow for targeted early intervention for children at risk of poorer outcomes.

Vision Res 2021; 183:73-80. [PMID: 33735759 DOI: 10.1016/j.visres.2020.09.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 08/31/2020] [Accepted: 09/03/2020] [Indexed: 10/21/2022]
Abstract
The purpose of the study was to determine the frequency of vision diagnoses after concussion in adolescents and evaluate the sensitivity and specificity of physician-administered screening for detecting convergence and accommodative disorders post-concussion. We enrolled participants 11 to 17 years old, assessed 4 to 12 weeks following a diagnosed concussion. During the initial concussion examination, a sports medicine physician measured the near point of convergence (NPC), monocular accommodative amplitude (AA), and symptoms using the Convergence Insufficiency Symptom Survey (CISS). A comprehensive oculomotor evaluation was performed by an optometrist. One hundred and thirteen adolescents were enrolled, with a mean age of 15.2 years. Seventy-nine of the 113 (70%) participants had at least one oculomotor diagnosis after concussion, with the most common problems being vergence disorders (60%) and accommodative disorders (57%). The most common vergence disorder was convergence insufficiency (35%). Among accommodative disorders, the most common problem was accommodative insufficiency (35%). In all, 47% of the participants had more than one oculomotor diagnosis following concussion. The sensitivity of physician screening using measures of NPC, AA, and CISS for detecting convergence and accommodative insufficiency was 63%, 43%, 48%, respectively. The results of this study provide additional evidence that vision problems are common in adolescents with persistent concussion symptoms in the sub-acute phase 4 to 12 weeks post-concussion, and current physician screening methods using the NPC, AA, or the CISS underperform. Thus, it is prudent that adolescents with post-concussion symptoms lasting more than 4 weeks post injury receive a comprehensive oculomotor examination.

Abstract
Concussion and persistent postconcussive symptoms (PPCS) are encountered by clinicians in sports medicine, pediatrics, neurology, physiatry, emergency medicine, and primary care. Clinical management may require a multidisciplinary approach. This article presents a structured method for the diagnosis of concussion and PPCS in the outpatient setting, which includes a history, physical examination, and additional tests as clinically indicated to help identify underlying symptom generators. Treatment for concussion and PPCS should be individualized, based on predominant signs and symptoms, and can include subsymptom threshold aerobic exercise, cervical physical therapy, vestibulo-ocular rehabilitation, behavioral and cognitive psychotherapy, and some symptom-specific pharmacological therapies.

Abstract
CONTEXT Emerging research supports the use of mild to moderate aerobic exercise for treating sport-related concussion (SRC) and persistent postconcussive symptoms (PPCS), yet the current standard of care remains to be strict rest. The purpose of this review is to summarize the existing literature on physical activity and prescribed exercise for SRC and PPCS. EVIDENCE ACQUISITION PubMed and Embase were searched in April of 2019 for studies assessing rest or prescribed exercise for SRC and PPCS. No specific search syntax was used. STUDY DESIGN Clinical review. LEVEL OF EVIDENCE Level 4. RESULTS A majority of studies show that spontaneous physical activity is safe after SRC and that subsymptom threshold aerobic exercise safely speeds up recovery after SRC and reduces symptoms in those with PPCS. Exercise tolerance can safely be assessed using graded exertion test protocols within days of injury, and the degree of early exercise tolerance has diagnostic and prognostic value. CONCLUSION Subsymptom threshold aerobic exercise is safe and effective for the treatment of SRC as well as in athletes with PPCS. Further research is warranted to establish the most effective method and dose of aerobic exercise for the active treatment of SRC and whether early exercise treatment can prevent PPCS in athletes. STRENGTH OF RECOMMENDATION TAXONOMY 2.

Abstract
INTRODUCTION While most children recover from a concussion shortly after injury, approximately 30% experience persistent postconcussive symptoms (pPCS) beyond 1-month postinjury. Existing research into the treatment of pPCS have evaluated unimodal approaches, despite evidence suggesting that pPCS likely represent an interaction across various symptom clusters. The primary aim of this study is to evaluate the effectiveness of a multimodal, symptom-tailored intervention to accelerate symptom recovery and increase the proportion of children with resolved symptoms at 3 months postconcussion. METHODS AND ANALYSIS In this open-label, assessor-blinded, randomised clinical trial, children with concussion aged 8-18 years will be recruited from The Royal Children's Hospital (The RCH) emergency department, or referred by a clinician, within 17 days of initial injury. Based on parent ratings of their child's PCS at ~10 days postinjury, symptomatic children (≥2 symptoms at least 1-point above those endorsed preinjury) will undergo a baseline assessment at 3 weeks postinjury and randomised into either Concussion Essentials (CE, n=108), a multimodal, interdisciplinary delivered, symptom-tailored treatment involving physiotherapy, psychology and education, or usual care (UC, n=108) study arms. CE participants will receive 1 hour of intervention each week, for up to 8 weeks or until pPCS resolve. A postprogramme assessment will be conducted at 3 months postinjury for all participants. Effectiveness of the CE intervention will be determined by the proportion of participants for whom pPCS have resolved at the postprogramme assessment (primary outcome) relative to the UC group. Secondary outcome analyses will examine whether children receiving CE are more likely to demonstrate resolution of pPCS, earlier return to normal activity, higher quality of life and a lower rate of utilisation of health services, compared with the UC group. ETHICS AND DISSEMINATION Ethics were approved by The RCH Human Research Ethics Committee (HREC: 37100). Parent, and for mature minors, participant consent, will be obtained prior to commencement of the trial. Study results will be disseminated at international conferences and international peer-reviewed journals. TRIAL REGISTRATION NUMBER ACTRN12617000418370; pre-results.

Abstract
Currently health care pathways (the combination and order of services that a patient receives to manage their injury) following a mild traumatic brain injury vary considerably. Some clinicians lack confidence in injury recognition, management and knowing when to refer. A clinical expert group developed the Brain Injury Screening Tool (BIST) to provide guidance on health care pathways based on clinical indicators of poor recovery. The tool aims to facilitate access to specialist services (if required) to improve longer term prognosis. The tool was developed using a three-step process including: 1) domain mapping; 2) item development and 3) item testing and review. An online retrospective survey of 114 adults (>16 years) who had experienced a mild brain injury in the past 10 years was used to determine the initial psychometric properties of the 15-item symptom scale of the BIST. Participants were randomised to complete the BIST and one of two existing symptom scales; the Rivermead Post-concussion Symptom Questionnaire (RPQ) or the Sports Concussion Assessment Test (SCAT-5) symptom scale to determine concurrent validity. Participant responses to the BIST symptom scale items were used to determine scale reliability using Cronbach's alpha. A principal components analysis explored the underlying factor structure. Spearman's correlation coefficients determined concurrent validity with the RPQ and SCAT-5 symptom scales. The 15 items were found to require a reading age of 6-8 years old using readability statistics. High concurrent validity was shown against the RPQ (r = 0.91) and SCAT-5 (r = 0.90). The BIST total symptom scale (α = 0.94) and the three factors identified demonstrated excellent internal consistency: physical/emotional (α = 0.90), cognitive (α = 0.92) and vestibular-ocular (α = 0.80). This study provides evidence to support the utility, internal consistency, factor structure and concurrent validity of the BIST. Further research is warranted to determine the utility of the BIST scoring criteria and responsiveness to change in patients.

Abstract
Purpose: The objective of this study was to estimate the scope of concussion management practices for youth used by Canadian rehabilitation clinicians. A secondary objective was to determine the use of aerobic exercise as a management strategy. Method: Members of the Canadian Association of Occupational Therapists, Canadian Athletic Therapists Association, and Canadian Physiotherapy Association were invited to participate in an online cross-sectional survey. Two clinical vignettes were provided with a brief history. The respondents were asked about the type of treatments they would provide (e.g., manual therapy, education, aerobic exercise, return-to-learn or return-to-play protocol, goal setting). Results: The survey was completed by 555 clinicians. The top five treatment options were education, sleep recommendations, goal setting, energy management, and manual therapy. Just more than one-third of the clinicians prescribed aerobic exercise. Having a high caseload of patients with concussion (75%-100%) was a significant predictor of prescribing aerobic exercise. Conclusions: A wide variety of treatment options were selected, although the most common were education, sleep recommendations, energy management, and goal setting. Few clinicians used aerobic exercise as part of their concussion management strategy.

Abstract
OBJECTIVES To prospectively investigate the recovery of athlete-reported symptoms and the condition-specific health-related quality of life (HRQoL) following sport-related concussion. DESIGN Prospective matched-cohort study. METHODS We recruited amateur athletes who were diagnosed with sport-related concussion by emergency department physicians. Study participants were assessed at 3 time points following sport-related concussion. At each assessment, participants completed 5 condition-specific HRQoL patient-reported outcome measures to evaluate participants' perceptions of the effects of specific concussion-related symptoms on their HRQoL. We performed log-linear analyses to assess the proportion of concussed participants with clinically impaired condition-specific HRQoL compared with the proportion of participants in the control group with clinically impaired condition-specific HRQoL. RESULTS Fifty participants with sport-related concussion and 50 control participants matched by sex, age, and activity completed the study. Upon return to sporting activity, there was a significantly greater proportion of participants in the concussion group who perceived that headache, neck pain, and dizziness had an adverse effect on their HRQoL compared with the control group. Two weeks after return to sporting activity, there was still a significantly greater proportion of participants in the concussion group who perceived that headache (χ21 = 9.0; odds ratio [OR] = 4.4; 95% confidence interval [CI]: 1.5, 15.2; P = .003) and dizziness (χ21 = 9.5; OR = 13.5; 95% CI: 1.8, 604.9; P = .006) had an adverse effect on their HRQoL compared with the proportion of clinically impaired participants in the control group. CONCLUSION Of concussed participants, 1 in 4 perceived that headache and dizziness had adverse effects on their HRQoL after returning to sporting activity following sport-related concussion compared with nonconcussed, control participants.

Abstract
OBJECTIVES The main purpose of this study was to explore the effectiveness of an integrated interprofessional management (IPM) concussion care approach in varsity athletes. SETTING The study was completed in a university environment with varsity athletes. DESIGN Data analysis was quantitative, as compared between seasons, in this observational cohort study. MAIN OUTCOME MEASURES The metrics for the effectiveness of the IPM team were: time spent in treatment and post-concussion symptom severity scores. These measures were compared for each season year and both sexes for the primary concussive domain they were initially diagnosed with. PARTICIPANTS University varsity athletes from various in-season teams. RESULTS A Kruskal-Wallis revealed that 2017/18 athletes spent a significantly shorter amount of time in treatment between the two seasons, median 29 days in the 2016/17 season year (IQR = 29) versus 13 days in the 2017/18 season year (IQR = 11), for both sexes (p = 0.009). It appears women tended to recover more quickly than men, particularly in the 2016/2017 season first year. CONCLUSIONS A highly communicative interprofessional management (IPM) strategy was shown to lead to reduced return to play (RTP) and return to learn (RTL) times. Increased experience as an IPM team may be a factor contributing to the effectiveness in IPM strategies as well as overall concussion treatment.

Abstract
Traumatic brain injury (TBI) accounts for significant global health burden. Effects of TBI can become chronic even following mild injury. There is a need to develop effective therapies to attenuate the damaging effects of TBI and improve recovery outcomes. This literature review using a priori criteria (PROSPERO; CRD42018100623) summarized 43 studies between January 1998 and July 2019 that investigated nutritional interventions (NUT) delivered with the objective of altering neurophysiological (NP) outcomes following TBI. Risk of bias was assessed for included studies, and NP outcomes recorded. The systematic search resulted in 43 of 3,748 identified studies met inclusion criteria. No studies evaluated the effect of a NUT on NP outcomes of TBI in humans. Biomarkers of morphological changes and apoptosis, oxidative stress, and plasticity, neurogenesis, and neurotransmission were the most evaluated NP outcomes across the 43 studies that used 2,897 animals. The risk of bias was unclear in all reviewed studies due to poorly detailed methodology sections. Taking these limitations into account, anti-oxidants, branched chain amino acids, and ω-3 polyunsaturated fatty acids have shown the most promising pre-clinical results for altering NP outcomes following TBI. Refinement of pre-clinical methodologies used to evaluate effects of interventions on secondary damage of TBI would improve the likelihood of translation to clinical populations.

Abstract
Concussive brain injury (CBI) is encountered by clinicians in sports medicine, pediatrics, neurosurgery, neurology, physiatry, and primary care. There is no gold standard diagnostic test for CBI, nor is there consensus on what neuromusculoskeletal physical examination tests should be performed on patients who have sustained CBI. This article presents an approach to the history and physical examination of the patient who has sustained a CBI that is based on a review of the literature evidence and the authors' extensive experience with this patient population. Suggested components include an elemental neurological examination that emphasizes the oculomotor/ophthalmologic and vestibular systems, as well as appropriate musculoskeletal assessment of the craniocervical and upper shoulder girdle complex. The use of supplementary tests for CBI, including assessment of exercise tolerance using the Buffalo Concussion Treadmill Test and tests of neurocognitive function, can aid in the differential diagnosis of CBI. The proposed protocol is envisioned for initial and follow-up assessments in the clinic after CBI, as well as for those with more protracted signs or symptoms. If symptoms persist beyond 2 weeks in adults or 4 weeks in adolescents, then referral to a multidisciplinary center that focuses on CBI is recommended.

PURPOSE To examine interrelationships among Vestibular/Ocular-Motor Screen (VOMS) items and to characterize the recovery of VOMS performance in a sample of adolescents treated with vestibular physical therapy (VPT) after concussion. METHODS Seventy-seven patients with concussion and 77 participants without concussion completed the study. Adolescents with concussion received an individualized VPT intervention consisting of targeted exercises for gaze stability, postural stability, ocular-motor control, habituation, and aerobic activities. The exercises were performed during a weekly clinic visit and via a home exercise program. RESULTS Except for near-point convergence distance, all VOMS items were significantly interrelated. Over the course of VPT, significant improvements in VOMS performance were observed, and discharge scores were similar to scores observed in adolescents without concussion. CONCLUSIONS The VOMS measured moderately related functions and captured changes over the course of VPT. Clinicians should consider the contextual risk of "false positive" in their interpretation of VOMS.

Abstract
After traumatic brain injury (TBI), a host of symptoms of varying severity and associated functional impairment may occur. One of the most commonly encountered and challenging to treat are the post-traumatic cephalalgias. Post-traumatic cephalalgia (PTC) or headache is often conceptualized as a single entity as currently classified using the ICHD-3. Yet, the terminology applicable to the major primary, non-traumatic, headache disorders such as migraine, tension headache, and cervicogenic headache are often used to specify the specific type of headache the patients experiences seemingly disparate from the unitary definition of post-traumatic headache adopted by ICHD-3. More complex post-traumatic presentations attributable to brain injury as well as other headache conditions are important to consider as well as other causes such as medication overuse headache and medication induced headache. Treatment of any post-traumatic cephalalgia must be optimized by understanding that there may be more than one headache pain generator, that comorbid traumatic problems may contribute to the pain presentation and that pre-existing conditions could impact both symptom complaint, clinical presentation and recovery. Any treatment for PTC must harmonize with ongoing medical and psychosocial aspects of recovery.

Abstract
OBJECTIVE To (1) quantify the diagnostic accuracy of the vestibular/oculomotor screening (VOMS), and (2) determine the recovery of vestibular and oculomotor impairments exhibited by concussed athletes compared with nonconcussed athletes using the VOMS. SETTING Clinical assessment laboratory. PARTICIPANTS Amateur athletes who were diagnosed with sport-related concussion by emergency department physicians, and non-concussed, control athletes. DESIGN Prospective, longitudinal study. MAIN MEASURES Participants were assessed 1 week following sport-related concussion, upon clearance to return-to-sporting activity, and 2 weeks following return-to-sporting activity by a study investigator who administered the VOMS. We calculated test sensitivity, specificity, and positive and negative predictive values to estimate the diagnostic accuracy of the VOMS. We performed a mixed-design analysis of variance to assess differences in VOMS symptom scores reported by concussed athletes compared with control athletes. RESULTS Fifty concussion participants and 50 control participants completed the study. The VOMS demonstrated sensitivity and specificity of 96% and 46%, respectively, and produced positive and negative predictive values of 64% and 92%, respectively. The concussion group exhibited a significantly greater symptom provocation change score from baseline than the control group for all test domains of the VOMS only in the first week following concussion. CONCLUSION The VOMS may be most useful as a clinical screening tool to rule out, rather than confirm, the presence of sport-related concussion. The VOMS may be appropriate to inform the recovery of vestibular and oculomotor impairments exhibited by concussed individuals over time.

Abstract
This article presents a brief, focused physical examination [PE, the Buffalo Concussion Physical Examination (BCPE)] for sport-related concussion (SRC) to be considered for use in the outpatient setting by sports medicine physicians, pediatricians, and primary-care physicians. This companion paper describes how to perform the PE, which was derived in a separate study presented in this journal. It is envisioned for use at the initial and follow-up outpatient visits both for acute concussions and in patients with prolonged symptoms. A pertinent PE, combined with other assessments, can help identify specific treatment targets in those with persistent symptoms after SRC. The BCPE includes orthostatic vital signs and examinations of the cranial nerves, oculomotor/ophthalmologic, cervical, and vestibular systems. Supplementary tests, including testing for exercise tolerance and neurocognitive function, may be performed if indicated. It is recommended that a PE be performed at the initial visit and every 1 to 2 weeks after SRC. On return of symptoms, cognition, and the PE to baseline, as well as normalization of any supplementary tests, patients can begin a return to play program.

Abstract
The Concussion Office Based Rehabilitation Assessment (COBRA) is a novel tool constructed to ensure a comprehensive assessment of patients who may have sustained a concussion. The SCAT-5 (Sport Concussion Assessment Tool) has long been the gold standard for concussion assessment, however, it was designed as a sideline tool and its utility can be seen to decrease after a few days post-concussion. It also does not prompt evaluation of all the phenotypes of concussion. As such, the COBRA was created to assess the majority of potential manifestations of concussion in the office setting a day or two after an injury has been sustained. The COBRA utilizes the eight phenotypes of concussion as a guide to assess each of the potential biopsychosocial features that can be associated with these injuries and can be used to guide evidence-based treatments. Through early identification of concussion phenotypes, the clinician may start optimal treatment and hopefully prevent prolonged recovery and persisting symptoms.

Abstract
BACKGROUND Acute neck pain (ANP) has recently been demonstrated to be a predictor of persistent posttraumatic complaints after mild traumatic brain injury (mTBI). The aim of this study was to determine specific characteristics of patients with ANP following mTBI, their posttraumatic complaints and relationship with functional outcome. METHODS Data from a prospective follow-up study of 922 mTBI patients admitted to the emergency department (ED) in three level-one trauma centres were analysed. Patients were divided into two groups: 156 ANP patients and 766 no acute neck pain (nANP) patients. Posttraumatic complaints were evaluated 2 weeks and 6 months post-injury using standardized questionnaires and functional outcome was evaluated at 6 months with the Glasgow Outcome Scale Extended (GOSE). RESULTS ANP patients were more often female (p < 0.01), younger (38 vs. 47 years, p < 0.01) with more associated acute symptoms at the ED (p < 0.05) compared to nANP patients. More motor vehicle accidents (12% vs. 6%, p = 0.01) and less head wounds (58% vs. 73%, p < 0.01) in ANP patients indicated 'high-energy low-impact' trauma mechanisms. ANP patients showed more posttraumatic complaints 2 weeks and 6 months post-injury (p < 0.05) and more often incomplete recovery (GOSE < 8) was present after 6 months (56% vs. 40%, p = 0.01). CONCLUSIONS MTBI patients with acute neck pain at the ED constitute a distinct group within the mTBI spectrum with specific injury and demographic characteristics. Early identification of this at risk group already at the ED might allow specific and timely treatment to avoid development of incomplete recovery.

Increased Risk of Musculoskeletal Injury Following Sport-Related Concussion: A Perception-Action Coupling Approach. Sports Med 2020; 50:15-23.

Abstract
Recent studies have concluded that athletes have increased risk of musculoskeletal injury following sport-related concussion. While an underlying explanation is still unknown, perceptual-motor control may be implicated in this increased risk. Some authors have purported that indirect perception (i.e., a "top-down" view of neuromuscular control) may be disrupted following sport-related concussion. Direct perception theory states that the athlete and environment are inextricably linked in a continuous perception-action coupling loop. That is, the athlete is able to directly perceive opportunities for action (e.g., "affordances") in the environment. Based on these notions, the aim of the current paper was to introduce a theoretical model that argues that sport-related concussion may dysregulate the direct perception process, potentially increasing behavioral risk of musculoskeletal injury during sport. Our model is integrated with a sport-related concussion clinical treatment model, which highlights individualized profiles that characterize the heterogeneous response to sport-related concussion. These profiles have a typical constellation of symptoms (e.g., anxiety, fatigue, ocular dysfunction, etc.), which themselves have been associated with disrupted perception-action coupling, independent of sport-related concussion. Therefore, we argue that athletes who have not re-established perception-action coupling loops following sport-related concussion may be at increased risk of subsequent musculoskeletal injury.

Abstract
Sport-related concussion (SRC) is a heterogenous injury with diverse symptoms and impairments that can be aggregated into clinical subtypes (cognitive, headache/migraine, vestibular, ocular-motor, anxiety/mood). Sleep disruption has been defined as potential exacerbating conditions that may accompany the five clinical subtypes. The authors sought to better characterize the role of impaired sleep in each clinical subtype and to identify other risk factors for sleep impairment after SRC. 281 patients (15.3 ± 2.1 years) aged 10-22 years within 21 days of SRC completed the Post-Concussion Symptom Scale (PCSS), the Vestibular/Ocular Motor Screening (VOMS), and a clinical assessment to identify clinical subtype. Subjects were then divided into HIGH (≥7; n = 82) and LOW (≤3; n = 132) sleep symptom groups for comparison. HIGH participants had greater proportions of females (p < 0.001), history of psychiatric disorder (p < 0.001); total PCSS (p < 0.001); and impairment on all VOMS items (p < 0.001). HIGH participants were associated with mood/anxiety (p < 0.001), vestibular (p = 0.003) and ocular (p = 0.03) subtypes. Results of a logistic regression (LR) model with adjusted odds ratios (OR) to predict HIGH sleep symptoms supported anxiety/mood profile (OR = 2.98), vestibular profile (OR = 2.81), psychiatric history (OR = 4.99), and history of motion sickness (OR = 2.13) as significant predictors. Prescribing behavioral and sleep interventions may improve outcomes in cases where these factors co-occur.

Abstract
Head injuries can result in substantially different outcomes, ranging from no detectable effect to transient functional impairments to life‐threatening structural lesions. In high‐level international football (soccer) tournaments, on average, one head injury occurs in every third match. Making the diagnosis and determining the severity of a head injury immediately on‐pitch or off‐field is a major challenge for team physicians, especially because clinical signs of a brain injury can develop over several minutes, hours, or even days after the injury. A standardized approach is useful to support team physicians in their decision whether the player should be allowed to continue to play or should be removed from play after head injury. A systematic, football‐specific procedure for examination and management during the first 72 hours after head injuries and a graduated Return‐to‐Football program for high‐level players have been developed by an international group of experts based on current national and international guidelines for the management of acute head injuries. The procedure includes seven stages from the initial on‐pitch examination to the graduated Return‐to‐Football program. Details of the assessments and the consequences of different outcomes are described for each stage. Criteria for emergency management (red flags), removal from play (orange flags), and referral to specialists for further diagnosis and treatment (persistent orange flags) are provided. The guidelines for return to sport after concussion‐type head injury are specified for football. Thus, the present paper presents a comprehensive procedure for team physicians after a head injury in high‐level football.

Abstract
While the majority of individuals make full recovery within a short period following mild traumatic brain injury (mTBI), some continue to experience a more chronic course of symptoms termed persistent post-concussive symptoms (PPCS). Previous models and conceptualizations of PPCS have typically not differentiated the time at which factors present across the injury timeline spectrum or have considered a limited array of contributory factors. In the current review, PPCS are examined within the predisposing, precipitating, and perpetuating (PPP) model, which has been applied to explain other syndromes resulting in a clear framework to explain, disseminate, and further research the specified condition. Previous PPCS models are reviewed and integrated into this comprehensive model, as well. To do so, a literature review was completed which included previous PPP models applied to other conditions, other PPCS models, and more recent findings of factors related to PPCS. This new iteration and application of the PPP model more clearly, completely, and validly identifies contributing factors to PPCS. Future prevention, early identification, clearer questions for future research, and treatment of PPCS is possible with clarity provided by this model.
