De Luigi AJ, Bell KR, Bramhall JP, Choe M, Dec K, Finnoff JT, Halstead M, Herring SA, Matuszak J, Raksin PB, Swanson J, Millett C. Consensus statement: An evidence-based review of exercise, rehabilitation, rest, and return to activity protocols for the treatment of concussion and mild traumatic brain injury. PM R 2023; 15:1605-1642. [PMID: 37794736 DOI: 10.1002/pmrj.13070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 07/24/2023] [Accepted: 07/28/2023] [Indexed: 10/06/2023]
Abstract
BACKGROUND Early diagnosis and appropriate management of concussion/mild traumatic brain injury (mTBI) is critical for preventing poor outcomes and minimizing health care burden. Current clinical guidelines for concussion management focus mostly on diagnosis and return to cognitive and physical activity but provide limited guidance on the use of specific therapeutic interventions. OBJECTIVE To systematically review the available evidence on therapeutic interventions for concussion/mTBI and develop an evidence-based consensus statement on the use of these interventions in clinical practice. LITERATURE SURVEY A systematic literature search was performed first in 2018 and 2019, and again in 2022, to identify relevant original research on these interventions. A total of 6303 articles were retrieved through the systematic literature search and screened for inclusion. Eighty articles met inclusion criteria and were included in this review and consensus process. METHODOLOGY A multispecialty panel was convened to explore management of concussion/mTBI. Interventions evaluated included rest, exercise, rehabilitation, and return to activity (RTA) protocols. Studies were assessed for relevance and methodologic quality and were voted upon to develop an evidence-based consensus statement on the therapeutic appropriateness of these interventions for concussion/mTBI. A meta-analysis was not performed. SYNTHESIS There was sufficient evidence to recommend exercise as an appropriate therapy for adolescents with acute concussion/mTBI. In other age groups and for other therapeutic modalities, although some studies demonstrated benefits for some of the interventions, mixed results and study limitations prevented the panel from drawing firm conclusions on the efficacy of those interventions. The panel found evidence of detrimental effects from strict rest and high-intensity physical activity. CONCLUSIONS The panel recommended exercise as an appropriate therapy for acute concussion in adolescents. The evidence on other therapeutic interventions for concussion/mTBI remains limited to small randomized controlled trials and observational studies of moderate to low quality. The panel found no strong evidence to support or recommend against the other evaluated interventions but found most interventions to be safe when used judiciously and in consideration of individual patient needs. High-quality randomized studies with sufficient power are needed to evaluate the effects of rest, rehabilitation, and RTA protocols for the management of concussion/mTBI.

Interdisciplinary rehabilitation for persisting post-concussion symptoms after mTBI: N=15 single case experimental design. Ann Phys Rehabil Med 2023; 66:101777. [PMID: 37890339 DOI: 10.1016/j.rehab.2023.101777] [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: 11/27/2022] [Revised: 06/09/2023] [Accepted: 06/15/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Despite clinical guidelines recommending an interdisciplinary approach to persisting post-concussion symptom (PPCS) management, evaluations of interdisciplinary interventions remain scant. OBJECTIVES This pilot study aimed to explore the feasibility and preliminary efficacy of an interdisciplinary intervention for PPCSs. METHOD A single-case experimental design with randomisation to multiple baselines (2, 4, or 6 weeks) was repeated across 15 participants (53% female) with mild traumatic brain injury (mean age 38.3 years, SD 15.7). The 12-week treatment incorporated psychology, physiotherapy, and medical interventions. Feasibility outcomes included recruitment and retention rates, adverse events, treatment adherence and fidelity. Patient-centred secondary outcomes included the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), assessed 3 times per week during the baseline and treatment phases, and at the 1- and 3-month follow-ups. Other secondary outcomes included measures of mood, sleep and fatigue, physical functioning, health-related quality of life, illness perceptions, and goal attainment. Changes in PPCSs were evaluated using systematic visual analysis and Tau-U. Clinically significant changes in secondary outcomes were explored descriptively. RESULTS 16/26 individuals assessed for eligibility were enroled (61% recruitment rate); 15 completed the post-treatment follow-ups, and 13 completed the 1- and 3-month follow-up assessments (81% retention rate). High treatment adherence and competence in delivering treatments was observed. Moderate-large effect sizes for reducing PPCSs were observed in 12/15 cases, with 7/15 reaching statistical significance. Improvements were maintained at the 1- and 3-month follow-ups and were accompanied by reductions in fatigue, sleep difficulties, and mood symptoms, and changes in illness perceptions. All participants had clinically significant improvements in at least 1 outcome, with 81% of individual therapy goals achieved. CONCLUSIONS This pilot study provided preliminary support for a subsequent randomised controlled trial (RCT), with satisfactory recruitment, retention, treatment compliance, and treatment fidelity. Improvement was evident on participant outcomes including symptom reduction and goal attainment, suggesting that progressing to a phase-II RCT is worthwhile. Findings highlight the potential benefit of individualized interdisciplinary treatments.

[PMID: 37283218 DOI: 10.1515/jom-2022-0217] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 04/27/2023] [Indexed: 06/08/2023]
Abstract
CONTEXT Concussions are the most common type of traumatic brain injury (TBI) and can often occur in athletes. These injuries have many deleterious acute symptoms and can lead to the development of postconcussive syndrome (PCS). Osteopathic manipulative treatment (OMT) is a treatment option that may benefit patients with concussions and PCS. OBJECTIVES The objective of this review is to determine whether OMT can improve symptoms associated with concussions and PCS in athletes. METHODS A comprehensive literature review was conducted between August 2021 and March 2022 by two authors (Z.K.L. and K.D.T.) who searched the literature utilizing PubMed, Google Scholar, and Cochrane Library. Articles reviewed included case reports, case studies, randomized control trials, meta-analyses, and peer-reviewed journal articles. Search terms included concussion, postconcussive symptoms, osteopathic manipulative medicine, and manipulation. To be included into this study, articles must have included OMT from an osteopathic physician or manipulative techniques by nonosteopathic providers for patients with a concussion or PCS, and the insulting injury must have occurred in an athletic setting. No disagreements occurred between authors about what studies to include. However, we were prepared to come to a unanimous decision through discussion among the authors. A narrative synthesis was performed. No other data analyses were conducted in this study. RESULTS Included in this review were nine articles including randomized control trials, retrospective review, case series, longitudinal, retrospective studies, and case reports. The literature shows the positive effects of OMT and manipulative techniques on symptom resolution after a concussion. However, most of the literature is qualitative rather than quantitative in nature, lacking in randomized control trials. CONCLUSIONS There is a scarcity of high-quality studies evaluating the effectiveness of OMT on concussions and PCS. More research is needed to understand the degree of benefit for this treatment option.

Abstract
CONTEXT Exercise rehabilitation for postconcussion symptoms (PCS) has shown some benefits in adolescent athletes; but a synthesis of evidence on exercise per se has been lacking. OBJECTIVE This systematic review aimed to determine if unimodal exercise interventions are useful to treat PCS and if so, to identify a set of clearly defined and effective exercise parameters for further research. EVIDENCE ACQUISITION Relevant health databases and clinical trial registries were searched from inception to June 2022. The searches used a combination of subject headings and keywords related to mild traumatic brain injury (mTBI), PCSs, and exercise. Two independent reviewers screened and appraised the literature. The Cochrane Collaboration's Risk of Bias-2 tool for randomized controlled trials was used to assess methodological quality of studies. EVIDENCE SYNTHESIS Seven studies were included in the review. Four studies were assessed to have a low overall risk of bias, 2 with low risk and 1 with some concerns. Participants in the studies comprised mostly adolescents with sports-related concussion. The review found exercise to be more beneficial than control conditions in 2 studies investigating acute PCS and 2 studies investigating persistent PCS. Within-group differences showing symptom improvement over time were observed in all 7 studies. In general, the review found support for programmatic exercise that commences after an initial period of rest for 24 to 48 hours. Recommendations for exercise parameters that can be explored in subsequent research include progressive aerobic exercise starting from 10 to 15 minutes at least 4 times a week, at a starting intensity of 50% HR of the subsymptom threshold, with length of program depending on recovery. CONCLUSION The evidence in support of exercise rehabilitation for PCSs is moderate based on the small pool of eligible studies. Further research can be guided by the exercise parameters identified in this review.

Abstract
OBJECTIVE To examine associations between pre-existing anxiety symptoms, and symptoms and cognitive functioning acutely following a suspected concussion. DESIGN Nested case-control study. SETTING High schools in Maine, USA. PARTICIPANTS Participants were identified from a dataset of 46 920 student athletes ages 13 to 18 who received baseline preseason testing. A subset of 4732 underwent testing following a suspected concussion. Of those, 517 were assessed within 72 hours after their suspected concussion and met other inclusion criteria. Nineteen injured athletes endorsed anxiety-like symptoms on the Post-Concussion Symptom Scale (PCSS) during baseline testing and were placed in the high anxiety group. Each athlete was matched to 2 injured athletes who did not endorse high levels of anxiety-like symptoms (N = 57). MAIN OUTCOME MEASURES Immediate Post-Concussion Assessment and Cognitive Testing cognitive composite scores, PCSS total score, and symptom endorsement. RESULTS Cognitive composite scores were similar between groups across testing times ( = 0.004-0.032). The high anxiety group endorsed a greater number of symptoms than the low anxiety group ( = 0.452) and rated symptoms as more severe ( = 0.555) across testing times. Using a modified symptom score that excluded anxiety-like symptoms, a mixed analysis of variance indicated a group by injury interaction ( = 0.079); the high anxiety group reported greater increases in overall symptom severity following injury. CONCLUSIONS Adolescent athletes who have an anxious profile at baseline are likely to experience greater symptom burden following injury. Consideration of pre-injury anxiety may inform clinical concussion management by tailoring intervention strategies (eg, incorporating mental health treatments) to facilitate concussion recovery.

Abstract
OBJECTIVE To evaluate the evidence related to how physical activity (PA) affects recovery following a sport-related concussion (SRC) in adolescents. DESIGN Systematic review Data Source: PUBMED, MEDLINE, and SPORTDiscus Eligibility criteria for selecting study:(1) original research article (e.g., randomized controlled trials (RCT), quasi-experimental designs, cohort, case-control studies), (2) 66% or greater of the sample has to have a SRC diagnosed by a clinician, (4) human research, (5) evaluate the effect of a SRC on PA in adolescents only (<18 years). Participants were seen within 1-2 weeks post-SRC for acute studies and 4 weeks post-SRC for studies focused on prolonged recoveries. RESULTS Twenty-two studies met the inclusion criteria (i.e., 8 regarding PA (PA-daily aerobic activity including light-moderate intensities), 8 evaluating active rehabilitation/exercise programs (20 minutes of daily aerobic exercise below symptom threshold), 6 examining a single bout of exertion). The methodological quality of the literature was assessed using the Downs and Black risk of bias (ROB) checklist. The ROB scores ranged from 7-24, with only two RCTs included. Studies demonstrated single bouts of exertion testing were safe and feasible. Daily PA or active rehabilitation/exercise programs led to a reduction in symptoms present and a decrease in number of days to medical clearance. CONCLUSION Following a brief period of rest (24-48 hours), individuals can gradually and safely return to PA below their physical symptom exacerbation thresholds. Further research is warranted to delineate how to optimize the timing, intensity, duration, and modality of PA impacts symptom resolution and physiological recovery following SRC.

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 Dysfunction of the autonomic cardiovascular system after a concussion is known to cause exercise intolerance due to symptoms exacerbation. The aim of this study was to compare athletes with symptoms of a sport-related concussion and healthy controls with regard to their heart rate during a graded exercise test and their heart rate recovery during the 5 min cool-down after the graded exercise test. Methods Sport-related concussion patients ( N = 61; 31% female) and controls ( N = 16; 50% female) participated in a graded exercise test on a cycle ergometer followed by 5 min active cool-down. Based on the results of graded exercise tests they were divided into four groups: (1) patients who reached the symptom threshold and had to stop the graded exercise test (symptom threshold; N = 39; 33.3% female), (2) patients with symptoms who finished the graded exercise test (S; N = 16; 25% female), (3) patients without symptoms (NS; N = 6; 33.3% female), (4) controls ( N = 16; 50% female). Main outcome measures Heart rate, severity of headache and dizziness during graded exercise test, heart rate recovery (median (heart rate recoveries/maximal heart rate) ± median absolute deviation (MAD)) 30, 60 and 300 s after the start of cool-down. Results Heart rate recovery at 30 s was significantly slower in symptom (0.95 ± 0.01) compared to all other groups ( p < 0.002; symptom threshold: 0.92 ± 0.02, NS: 0.91 ± 0.02, controls: 0.93 ± 0.02). Heart rate recovery at 60 s was significantly slower in symptom (0.90 ± 0.02) compared to the symptom threshold and controls ( p < 0.041; 0.86 ± 0.03, 0.85 ± 0.04). Heart rate recovery at 300 s was significantly slower in symptom threshold (0.72 ± 0.05) compared to controls ( p = 0.003; 0.66 ± 0.02). Conclusions Heart rate measurements in athletes with symptoms of sport-related concussion should be continued during cool-down after the graded exercise test, as dysfunction of the autonomic cardiovascular system might manifest also during cool-down.

Patterson Gentile C, Shah R, Irwin SL, Greene K, Szperka CL. Acute and chronic management of posttraumatic headache in children: A systematic review. Headache 2021; 61:1475-1492. [PMID: 34862612 DOI: 10.1111/head.14236] [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: 07/19/2021] [Revised: 08/19/2021] [Accepted: 09/20/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVES The goal of this paper is to provide a compilation of the evidence for the treatment of posttraumatic headache (PTH) in the pediatric population. Headache features and timing of therapy were considered. BACKGROUND Headache is the most common symptom following mild traumatic brain injury (mTBI), affecting more than 80% of children and adolescents. It is unclear whether treatment for PTH should be tailored based on headache characteristics, particularly the presence of migraine features, and/or chronicity of the headache. METHODS Systematic literature searches of PubMed, Embase, Scopus, and Cochrane databases (1985-2021, limited to English) were performed, and key characteristics of included studies were entered into RedCAP® (Prospero ID CRD42020198703). Articles and conference abstracts that described randomized controlled trials (RCTs), cohort studies, retrospective analyses, and case series were included. Participants included youth under 18 years of age with acute (<3 months) and persistent (≥3 months) PTH. Studies that commented on headache improvement in response to therapy were included. RESULTS Twenty-seven unique studies met criteria for inclusion describing abortive pharmacologic therapies (9), preventative pharmacotherapies (5), neuromodulation (1), procedures (5), physical therapy and exercise (6), and behavioral therapy (2). Five RCTs were identified. Studies that focused on abortive pharmacotherapies were completed in the first 2 weeks post-mTBI, whereas other treatment modalities focused on outcomes 1 month to over 1-year post-injury. Few studies reported on migrainous features (7), personal history of migraine (7), or family history of migraine (3). CONCLUSIONS There is limited evidence on the timing and types of therapies that are effective for treating PTH in the pediatric population. Prospective studies that account for headache characteristics and thoughtfully address the timing of therapies and outcome measurement are needed.

Abstract
OBJECTIVES 1) To determine which characteristics of adolescent athletes with SRC are associated with 'early' versus 'late' presentation for multimodal treatment; 2) to build a propensity score to investigate the effects of treatment timing during the management of SRCs. METHODS Associations between early (0-7 days) versus late (8-28 days) presentation for treatment and pre-specified sociodemographic, pre-injury and injury characteristics were investigated in a historical cohort study of 2949 multi-sport athletes across Canada aged 12-18 years diagnosed with a SRC in community-based healthcare clinics. RESULTS Early presentation was associated with being male, completing a pre-injury baseline assessment, and responding 'yes' or 'no' to having a diagnosed learning disability. Older athletes who reported previous SRCs were less likely to present early. The propensity score demonstrated an area under the curve of 0.71 (95% CI, 0.69 to 0.73). CONCLUSIONS Male athletes with a completed baseline assessment were more likely to seek early treatment following a SRC, and older athletes who reported a greater number of previous SRCs were less likely to present early. External validation of the propensity score is needed before examining the impact of treatment timing on adolescent athlete recovery outcomes.

Abstract
BACKGROUND AND OBJECTIVES Aerobic exercise has become a useful method to assist with post-concussion management. Exercise can exacerbate concussion symptoms even when symptoms are not apparent at rest. Few studies have examined the reasons for symptom exacerbation during exercise following a concussion. We had two primary objectives. 1) To delineate cardiopulmonary and cerebrovascular responses to exercise in adolescents and young adults with a concussion and healthy controls. 2) To determine the association between cerebrovascular responses and symptom burden. METHODS We recruited participants with a recent concussion from a sport concussion clinic between 9/1/2018-2/22/2020. They were included if their concussion occurred <3 weeks before initial testing and if they were symptomatic at rest. Participants were excluded if they sustained a concussion in the past year (excluding index injury), reported history of neurological disorders, or were using medications/devices that may alter neurological function. Participants completed a progressive, symptom-limited, sub-maximal exercise protocol on a stationary bike. We assessed heart rate, blood pressure, fraction of end tidal CO2 (FETCO2) and middle cerebral artery blood flow velocity (CBF) and cerebrovascular function (vasoreactivity and autoregulation) at seated rest and during exercise. RESULTS We conducted 107 exercise tests (40 concussed, 37 healthy participants initially; 30 concussed at follow-up). Concussed participants were tested initially (mean=17.6±2.2 [SD] years old; 55% female; mean=12.5±4.7 days post-concussion) and again 8 weeks later (mean=73.3±9.5 days post-concussion). Control participants (mean=18.3±2.4 years; 62% female) were tested once. FETCO2 increased throughout the exercise protocol as heart rate increased, reached a plateau, and declined at higher exercise intensities. CO2 explained >25% of the variation in resting CBF (R2>0.25; p<0.01) in most (73% individuals). Within the concussion group, resting symptom severity and the heart rate at which FETCO2 reached a plateau explained ∼two-thirds of variation in exercise-induced symptom exacerbation (R 2 =0.65; FETCO2 β=-1.210±0.517[S.E.], p<0.05). There was a moderate, statistically significant relationship between cerebrovascular responses to CO2 at rest (cerebral vasoreactivity) and cerebrovascular responses to exercise-induced changes in FETCO2 (R2=0.13, p=0.01). DISCUSSION The arterial CO2 response and symptom exacerbation relationship during post-concussion aerobic exercise may be mediated by increased sensitivity of cerebral vasculature to exercise-related increase in CO2.

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
PURPOSE This study aimed to conduct a systematic review and meta-analysis of active rehabilitation on concussion management. We also examined moderator variables that may contribute to differences across studies: symptom scale, physical activity type, time of injury to recruitment, and mechanism of injury. METHODS The standardized effect size of physical activity on concussion management was computed for 23 studies (29 effect sizes). Effect sizes were coded as positive when studies reported an improvement in symptom scores, which was represented by a decrease in postconcussive symptom scores. RESULTS The overall effect size of physical activity on concussion recovery was large and positive (g = 1.03). Subthreshold aerobic activity provided the largest effect size (g = 1.71), whereas multimodal interventions had a moderate effect size (g = 0.70). All other moderator variables produced positive effect sizes ranging from g = 0.59 to g = 1.46. CONCLUSIONS This systematic review and meta-analysis demonstrates that current evidence supports the notion that physical activity is beneficial in decreasing postconcussive symptoms in both the acute and chronic phases after concussion. The results indicate that unimodal subthreshold aerobic activity may be the best course of action compared with multimodal interventions. Despite this growing body of evidence, additional research is needed to determine the optimal intensity, duration, and time to initiation of aerobic exercise after concussion.

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.

Abstract
OBJECTIVE To document the characteristics, measured outcomes, and effectiveness of physical activity (PA) interventions designed to improve health-related outcomes in individuals with a mild traumatic brain injury (mTBI) to assist in rehabilitation quality improvement efforts of a TBI rehabilitation program. METHODS A scoping review following a 6-step iterative framework search across 5 databases (MEDLINE, CINAHL, PsycINFO, SPORTDiscuss, and EMBASE) and the gray literature (Google) was performed. Selected PA interventions were designed for individuals of all ages and any mechanism of injury (eg, sports-related and falls). Data were charted, collated, and summarized according to the Consensus on Exercise Reporting Template checklist and domains of the International Classification of Functioning, Disability and Health. Involvement of clinical experts ensured tailoring of the knowledge synthesis to meet clinical needs. RESULTS Thirty-five articles and 14 gray literature records were retained. Five types of PA interventions were identified with the majority being multimodal. Reporting of PA intervention characteristics was highly variable across studies; many details necessary for intervention replication are missing. Study outcomes focused primarily on improving body functions and symptoms of mTBI, and less frequently on activities, participation, and health-related quality of life. The methodological quality of studies varies. CONCLUSIONS Identified PA intervention types offer various management options for healthcare providers. PA interventions may improve a wide range of health-related outcomes supporting the inclusion of PA in the management of individuals of all ages with mTBI. Higher-quality research and better reporting about intervention characteristics is however needed.

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
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
Dysregulation of the autonomic nervous system (ANS) may play an important role in the development and maintenance of persistent post-concussive symptoms (PPCS). Post-injury breathing dysfunction, which is influenced by the ANS, has not been well-studied in youth. This study evaluated cardiorespiratory functioning at baseline in youth patients with PPCS and examined the relationship of cardiorespiratory variables with neurobehavioral outcomes. Participants were between the ages of 13-25 in two groups: (1) Patients with PPCS (concussion within the past 2-16 months; n = 13) and (2) non-injured controls (n = 12). Capnometry was used to obtain end-tidal CO2 (EtCO2), oxygen saturation (SaO2), respiration rate (RR), and pulse rate (PR) at seated rest. PPCS participants exhibited a reduced mean value of EtCO2 in exhaled breath (M = 36.3 mmHg, SD = 2.86 mmHg) and an altered inter-correlation between EtCO2 and RR compared to controls. Neurobehavioral outcomes including depression, severity of self-reported concussion symptoms, cognitive catastrophizing, and psychomotor processing speed were correlated with cardiorespiratory variables when the groups were combined. Overall, results from this study suggest that breathing dynamics may be altered in youth with PPCS and that cardiorespiratory outcomes could be related to a dimension of neurobehavioral outcomes associated with poorer recovery from concussion.

Pilot Study of Telehealth Delivered Rehabilitative Exercise for Youth With Concussion: The Mobile Subthreshold Exercise Program (MSTEP). Front Pediatr 2021; 9:645814. [PMID: 34123963 PMCID: PMC8193501 DOI: 10.3389/fped.2021.645814] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 03/08/2021] [Indexed: 11/26/2022] Open
Abstract
Background: Concussion is common, and up to 30% of youth develop persistent symptoms. Preliminary data suggests treatment with rehabilitative exercise is beneficial, but most programs require frequent in-person visits, which is challenging for youth in rural areas, and has been made more difficult for all youth during the COVID-19 pandemic. We have adapted an exercise intervention to be delivered via telehealth using Zoom and personal fitness devices, which could ensure access to this type of treatment. Objective: The goal of this study was to assess feasibility and acceptability of a telehealth delivered exercise intervention for concussion, the Mobile Subthreshold Exercise Program (MSTEP), and collect pilot data regarding efficacy. Materials and Methods: All youth received the 6-week MSTEP intervention which included wearing a Fitbit and setting exercise heartrate and duration goals weekly over Zoom with the research assistant. Youth completed standardized measures of concussive symptoms (Health Behavior Inventory, HBI), fear-avoidance (Fear of Pain Questionnaire, FOPQ) and health-related quality of life (Pediatric Quality of life Assessment, PedsQL), as well as a structured qualitative exit interview. We examined change in measures over time using mixed effects modeling, controlling for age, sex, prior concussion and duration of symptoms. We coded qualitative interviews using Thematic analysis. Results: We recruited 19 subjects, 79% female with average age 14.3 (SD 2.2) and mean duration of symptoms 75.6 days (SD 33.7). Participants wore the Fitbit on 80% of days, and completed 94% of surveys and 96% of Zoom calls. Concussive symptoms (HBI) decreased significantly over the 6 week intervention (-10.6, 95%CI: -16.0 to -5.1) as did fear-avoidance (-21.6, 95%CI: -29.8 to -13.5). PedsQL improved significantly during the same time period (+15.1, 95%CI: 8.6-21.6). Approximately three-quarters (76%) of youth rated their care as "excellent." Participants appreciated the structure of the guided exercise program and the support of the RA. They also enjoyed being able to track their progress with the Fitbit. Conclusion: This study provides evidence for the feasibility and acceptability of a telehealth delivered rehabilitative exercise intervention for youth with concussion. Further research utilizing a randomized controlled trial is needed to assess efficacy.

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
Background: Concussion management evidence supports the efficacy of gradual active rehabilitation for return to sport in adolescents, however there is paucity of evidence for non-sports-related concussion management.Purpose: The purpose of this case series is to describe the feasibility and practicality of an irritability-based step-by-step model to guide rehabilitation.Case Descriptions: Three adolescent patients diagnosed with concussion during a non-sports related event are described. Each adolescent was classified as high, moderate, or low irritability level based on symptom exacerbation with Vestibular/Ocular-Motor Screening (VOMS), physical exertion based on age-predicted maximum heart rate, and cervicogenic factors. Each Patient's intervention was progressed following the proposed irritability-based algorithm.Outcomes: Patients were assessed using the Brain Injury Functional Status Patient-Reported Outcome Measure, VOMS testing, and a Numeric Pain Rating Scale. Concluding each plan of care, all patients met or exceeded the minimal clinically important difference for age, gender, and risk-adjusted predicted measure on all outcome assessments. All patients returned to school and age-appropriate activities without symptom exacerbation.Conclusion: An irritability-based algorithm model for non-sports-related concussion management may be a practical and feasible treatment approach for adolescents.

Abstract
OBJECTIVE The primary objective is to evaluate the feasibility (safety and acceptability) of implementing early active rehabilitation (AR) for concussion management in youth with symptoms persisting 2 weeks after injury. A secondary and exploratory objective was to estimate the potential efficacy of early AR compared with standard AR. We hypothesize that AR at 2-weeks postconcussion will be safe and acceptable to patients. DESIGN Randomized clinical trial. SETTING The Montreal Children's Hospital of the McGill University Health Center (MCH-MUHC), a tertiary care pediatric teaching hospital affiliated with McGill University in Montreal, Canada. PARTICIPANTS Twenty youth aged 9 to 17 years old with postconcussion symptoms for at least 2 weeks. INTERVENTION Active rehabilitation (aerobic exercise, coordination drills, visualization, and education/reassurance) was administered by physiotherapists in-person, and then continued as a home program. METHODS Twenty participants were randomized to either early AR (initiated 2 weeks after injury) or standard AR (initiated 4 weeks after injury). RESULTS Two adverse events (one in each group) were identified through an online survey more than one-month postconcussion. Postconcussion symptoms decreased over time for both groups. CONCLUSIONS The results from this pilot study indicate that a full clinical trial estimating the efficacy of early AR (starting 2 weeks after injury) is feasible. Further study is needed to determine the superiority of this strategy over current treatment approaches.

Abstract
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
The growing number of concussions and mild traumatic brain injuries (mTBI) with the lack of evidence-based treatment options is a continuous health concern. This creates problems when evaluating and providing efficacious symptom management to patients suffering from post-concussion syndrome (PCS). Numerous pharmacological and non-pharmacological agents have been utilized in an attempt to treat PCS. Some of these approaches include physical therapy, analgesics, antidepressants, and nutraceuticals. Although these treatments have had some success, there has been inconsistent outcomes, with some examples of patients' symptoms worsening. Among pharmaceutical agents, fluoxetine has been a popular choice for the symptom management of PCS. Although some patients have had symptom resolution with the use of fluoxetine, there is still a lack of conclusive data. Of the several biochemical changes that occur in a patient's brain following a concussion, an increase in reactive oxygen species (ROS) is of particular concern. In order to counteract the responses of the brain, antioxidants, such as ascorbic acid, have been utilized to reverse the damaging cellular effects. However, this may inadvertently cause an increase in ROS, rather than a reduction. Although there is a lack of consistency in exactly when each treatment was used in the post-injury interval, it is important that we analyze the strengths and weaknesses of the most commonly used agents due to the lack of a set protocol. The studies were chosen in a non-exhaustive manner and were not consistent in patients' post-injury intervals, in addition to other baseline characteristics. However, over-arching claims that some treatments may benefit more than others can be made. This review evaluates both the pharmaceutical and non-pharmaceutical protocols that are most commonly utilized in post-concussive patients for their efficacy in treatment of post-concussive syndrome (PCS).

Abstract
BACKGROUND AND PURPOSE Eye movements may be adversely affected after mild traumatic brain injury (mTBI) and should be examined. The purpose of this topical review is to provide the clinician with the most up-to-date knowledge related to eye movement abnormalities, screening measures, and evidence related to exercise interventions that are designed to enhance outcomes in persons after mTBI. SUMMARY OF KEY POINTS Presence of eye misalignment such as tropias or phoria or symptoms with head/eye movements such as vestibulo-ocular reflex (VOR) × 1, saccades, or smooth pursuits may slow the person's recovery. Tools such as the Convergence Insufficiency Symptom Survey, the Vestibular/Ocular Motor Screening, the Pediatric Vestibular Symptom Questionnaire, and the Pediatric Visually Induced Dizziness questionnaire may aid in identifying visual concerns to target in the physical therapy intervention program. There is emerging evidence that vestibular rehabilitation enhances recovery in persons after mTBI. RECOMMENDATIONS FOR CLINICAL PRACTICE A thorough eye examination is highly recommended after mTBI to identify targeted areas for intervention.

Abstract
Over the last decade, numerous concussion evidence-based clinical practice guidelines (CPGs), consensus statements, and clinical guidance documents have been published. These documents have typically focused on the diagnosis of concussion and medical management of individuals post concussion, but provide little specific guidance for physical therapy management of concussion and its associated impairments. Further, many of these guidance documents have targeted specific populations in specific care contexts. The primary purpose of this CPG is to provide a set of evidence-based recommendations for physical therapist management of the wide spectrum of patients who have experienced a concussive event.

Abstract
BACKGROUND Clinical practice for rehabilitation after mild traumatic brain injury (mTBI) is variable, and guidance on when to initiate physical therapy is lacking. Wearable sensor technology may aid clinical assessment, performance monitoring, and exercise adherence, potentially improving rehabilitation outcomes during unsupervised home exercise programs. OBJECTIVE The objectives of this study were to: (1) determine whether initiating rehabilitation earlier than typical will improve outcomes after mTBI, and (2) examine whether using wearable sensors during a home-exercise program will improve outcomes in participants with mTBI. DESIGN This was a randomized controlled trial. SETTING This study will take place within an academic hospital setting at Oregon Health & Science University and Veterans Affairs Portland Health Care System, and in the home environment. PARTICIPANTS This study will include 160 individuals with mTBI. INTERVENTION The early intervention group (n = 80) will receive one-on-one physical therapy 8 times over 6 weeks and complete daily home exercises. The standard care group (n = 80) will complete the same intervention after a 6- to 8-week wait period. One-half of each group will receive wearable sensors for therapist monitoring of patient adherence and quality of movements during their home exercise program. MEASUREMENTS The primary outcome measure will be the Dizziness Handicap Inventory score. Secondary outcome measures will include symptomatology, static and dynamic postural control, central sensorimotor integration posturography, and vestibular-ocular-motor function. LIMITATIONS Potential limitations include variable onset of care, a wide range of ages, possible low adherence and/or withdrawal from the study in the standard of care group, and low Dizziness Handicap Inventory scores effecting ceiling for change after rehabilitation. CONCLUSIONS If initiating rehabilitation earlier improves primary and secondary outcomes post-mTBI, this could help shape current clinical care guidelines for rehabilitation. Additionally, using wearable sensors to monitor performance and adherence may improve home exercise outcomes.

Abstract
Aerobic exercise has received increasing attention in the scientific literature as a component of management for individuals who sustain a concussion. Because exercise training has been reported to reduce symptoms and improve function for those experiencing persistent postconcussion symptoms, it represents a potentially useful and clinically pragmatic rehabilitation technique. However, the specific exercise parameters that best facilitate recovery from concussion remain poorly defined and unclear. This review will provide a summary of the current understanding of the role of subsymptom exercise to improve outcomes after a concussion and will describe the exercise parameters that appear to be important. The latter will take into account the three pillars of exercise dose-frequency, duration, and intensity-to examine what is currently known. In addition, we identify important gaps in our knowledge of exercise as a treatment for those who develop persistent symptoms of concussion.

Abstract
Concussions are a public health concern that affects individuals across the life span. The multifaceted effects of concussion warrant an interdisciplinary management strategy that may include physical therapy. However, physical therapists may feel underprepared for clinical decision making following a concussive event. We propose a new treatment-based profiling model to help physical therapists manage patients following a concussive event. This profiling model, based on symptom type and intensity, disability status, and response to movement, prioritizes treatment emphasis on (1) symptom management, (2) movement system optimization, or (3) performance optimization. We consider contextual factors that modify treatment decision making and present examples of each treatment-based profile. J Orthop Sports Phys Ther 2019;49(11):829-841. doi:10.2519/jospt.2019.8869.

Abstract
BACKGROUND AND PURPOSE Vision and vestibular-related deficits are common after concussion and are associated with prolonged recovery times, substantially impacting the quality of life for children. The utility of targeted vestibular rehabilitation for these deficits in children after concussion is unknown. The purpose of this study was to determine whether active vestibular rehabilitation is associated with an improvement in visuovestibular signs and symptoms in children with concussion. METHODS A retrospective cohort study of children diagnosed with concussion and referred to vestibular rehabilitation between 2012 and 2014 was conducted. Patient-reported symptoms and visuovestibular performance measures were assessed in the medical practice and physical therapy settings. RESULTS One hundred nine children were included in the study with a mean age of 11.8 (3.4) years. Among this group, 59 (54%) were male and 48 (44%) had a sports-related concussion. Children presented to a pediatric sports medicine office and physical therapy a median of 24 (interquartile range [IQR], 14-42) and 55 (IQR, 39-94) days after injury, respectively. Concussion symptoms decreased from a median of 9 (IQR, 5-13) symptoms at initial evaluation to a median of 0 (IQR, 0-2) symptoms at final assessment. Performance on all visuovestibular tasks improved significantly over the course of therapy except for near point of convergence. For the 45 children who completed the Balance Error Scoring System at both initial and final therapy visits, there was a significant improvement in mean level of performance (P < 0.0001). Characteristics between those who completed a full versus partial course of physical therapy were similar. DISCUSSION AND CONCLUSIONS Vestibular rehabilitation in children with concussion is associated with improvement in symptoms as well as visuovestibular performance. This active intervention may benefit children with persistent symptoms after concussion. Future prospective studies are needed to determine the efficacy and optimal postinjury timing of vestibular rehabilitation.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A208).

Abstract
Supplemental Digital Content is Available in the Text. Background and Purpose: Postural orthostatic tachycardia syndrome (POTS) is increasingly recognized as a complication affecting recovery from concussion. Individuals with POTS demonstrate refractory dizziness, lightheadedness, cognitive dysfunction, fatigue, headache, chronic pain, nausea and gastrointestinal dysmotility, activity and exercise intolerance, syncope, and tachycardia. Subtypes of POTS may include hypovolemia, hyperadrenergic states, autonomic neuropathy, and underlying autoimmunity, which may variably impact response to rehabilitation in varying ways. The subtle presentation of POTS postconcussion is often mistaken for underlying anxiety, conversion disorder, or lack of motivation for recovery. This article will present clinical features of POTS that may arise after concussion, and propose a role for physical therapists in the diagnosis and management of POTS during concussion recovery. Summary of Key Points: Data recorded and entered into a database during clinic visits from a large pediatric institution indicate that 11.4% of individuals diagnosed with POTS report onset of symptoms within 3 months of sustaining a concussion. Activation of the sympathetic nervous system can result in lightheadedness, shortness of breath, chest pain, tachycardia, palpitations on standing or with exertion, and activity and exercise intolerance. Identified comorbidities in people with POTS such as joint hypermobility and autoimmune disorders can further influence recovery. Recommendations for Clinical Practice: Physical therapists may identify signs and symptoms of POTS in a subset of individuals who remain refractory to typical interventions and who exhibit symptom exacerbation with orthostatic activity. Incorporation of an individualized POTS exercise program into current established concussion interventions may be useful, with emphasis on initial recumbent exercises and ongoing physical therapy assessment of exercise tolerance for dosing of activity intensity and duration.

Abstract
BACKGROUND AND PURPOSE Physical therapy (PT) is a management strategy increasingly recognized to facilitate recovery after concussion. The purpose of this study was to investigate the safety and outcomes of multimodal impairment-based PT at varying time points after injury in youth diagnosed with concussion. METHODS Data were extracted retrospectively from medical records for patients who received PT for concussion-related impairments. Patient records were categorized into 3 cohorts on the basis of the timing of PT implementation: 0-20 days following injury (early intervention), 21 to 41 days following injury (middle intervention), and 42 or more days following injury (late intervention). The primary outcome measure was Post-Concussion Symptom Inventory score from the beginning to the end of the PT episode of care. Additional outcome measures included number of PT sessions, duration of PT episode of care (days), and occurrence of unplanned visits to a health care provider. RESULTS A total of 120 patient records (mean age of 14.77 years) were analyzed. Thirty-three, 39, and 48 individuals were categorized into the early, middle, and late intervention cohorts, respectively. There were no significant differences between intervention cohorts with regard to symptom change on the Post-Concussion Symptom Inventory from the beginning to the end of the PT episode of care, unplanned health care visits, number of PT sessions, or duration of PT episode of care. DISCUSSION AND CONCLUSIONS Early initiation of PT may be safe and tolerable. Future prospective studies are needed to explore the efficacy of PT services administered early following injury to help characterize an optimal care plan for youth following concussion.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A210).

A Randomized Controlled Trial Investigating the Feasibility and Adherence to an Aerobic Training Program in Healthy Individuals. J Sport Rehabil 2019; 28:692-698. [PMID: 29952695 DOI: 10.1123/jsr.2018-0007] [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: 01/08/2018] [Revised: 03/16/2018] [Accepted: 05/20/2018] [Indexed: 11/18/2022]
Abstract
CONTEXT Concussion management is moving from passive rest strategies to active interventions, including aerobic exercise therapy. Little information is available regarding the feasibility and adherence of these programs. OBJECTIVES To determine whether an aerobic exercise training program intended for rehabilitation in people with concussion is feasible. Healthy, nonconcussed subjects were studied in this phase 1 trial. DESIGN Phase 1 parallel-group, randomized controlled trial in a sample of healthy (nonconcussed), recreationally active university students. SETTING Laboratory. PATIENTS 40 healthy university students. METHODS Participants were equally randomized to acute concussion therapy intervention (ACTIVE) training or nontraining groups. All participants completed maximal cardiopulmonary exercise tests on a stationary cycle ergometer at 2 test sessions approximately 14 days apart. During this 2-week study period, ACTIVE training participants completed six 30-minute cycling sessions, progressing from 60% to 80% of the participant's individualized maximal oxygen consumption. A subset of participants (NACTIVE = 12, Nnontraining = 11) wore physical activity monitors throughout the 2-week study period. MAIN OUTCOMES MEASURES Study protocol and randomization effectiveness, exercise safety and adherence, and progressive intensity of the ACTIVE training procedures. RESULTS No adverse events occurred during any exercise sessions. Twelve ACTIVE training participants (60%) completed all training sessions, and every participant completed at least 4 sessions. Heart rate increased throughout the training period (P < .001), but symptom changes and training adherence remained stable despite the progressively increasing workload. ACTIVE training participants completed approximately 30 additional minutes of physical activity on training sessions days, although that was not statistically significant (P = .20). CONCLUSIONS University-aged students were adherent to the ACTIVE training protocol. Future research should investigate the safety and feasibility of aerobic training programs in acutely concussed individuals to determine their appropriateness as a clinical rehabilitation strategy.

Abstract
OBJECTIVE To estimate the time frame during which initiating an active rehabilitation intervention (aerobic exercise, balance, and sport specific skills) after concussion contributed to improvement in symptoms at follow-up in children and adolescents who are slow to recover (symptoms persisting beyond 2 weeks) from concussion. SETTING Concussion clinic at a tertiary care pediatric teaching hospital. PARTICIPANTS A total of 677 children and adolescents with concussion aged 7 to 18 years. DESIGN Case series of participants starting active rehabilitation less than 2, 2, 3, 4, 5, or 6 or more weeks postconcussion. MAIN MEASURE Symptom severity measured by the 22-item Post-Concussion Scale (PCS)-revised. RESULTS All patients experienced significant improvement of symptoms while participating in active rehabilitation, irrespective of the start time postonset. Patients initiating active rehabilitation at 2 (P < .001) or 3 (P = .039) weeks postinjury demonstrated lower symptom severity at follow-up than those starting at 6 weeks or later. Patients starting at 2 weeks had lower symptom severity than patients starting less than 2 (P = .02), 4 (P = .20), or 5 weeks postinjury (P = .04). Lastly, patients starting less than 2 and 6 weeks or more postinjury yielded equivalent outcomes. CONCLUSIONS The findings support the use of active rehabilitation in children and adolescents who are slow to recover from concussion. Participants starting active rehabilitation less than 2 weeks and up to 6 or more weeks postconcussion demonstrated significant symptom improvements, but improvement was observed in all groups, regardless of the time to start active rehabilitation.

Abstract
PURPOSE OF REVIEW Recent studies are challenging the utility of prolonged rest as treatment for concussion and postconcussion syndrome (PCS). The purpose of this paper is to review the evidence for active recovery from concussion and PCS. RECENT FINDINGS Emerging data identify the central role of autonomic nervous system (ANS) dysfunction in concussion pathophysiology. The exercise intolerance demonstrated by athletes after sport-related concussion may be related to abnormal ANS regulation of cerebral blood flow. As aerobic exercise training improves ANS function, sub-symptom threshold exercise treatment is potentially therapeutic for concussion. A systematic assessment of exercise tolerance using the Buffalo Concussion Treadmill Test has been safely employed to prescribe a progressive, individualized subthreshold aerobic exercise treatment program that can return patients to sport and work. Multiple studies are demonstrating the efficacy of an active approach to concussion management. SUMMARY Sustained rest from all activities after concussion, so-called 'cocoon therapy', is not beneficial to recovery. Evidence supports the safety, tolerability, and efficacy of controlled sub-symptom threshold aerobic exercise treatment for PCS patients. Further study should determine the efficacy and optimal timing, dose, and duration of subthreshold aerobic exercise treatment acutely after concussion because early intervention has potential to prevent PCS.

Musculoskelet Sci Pract 2019; 39:130-135.

Abstract
BACKGROUND Persistent post-concussion symptoms (PPCS) are complex, and typically involve multidisciplinary assessment and management. The neck and vestibulo-ocular systems are recognised as potential contributors to PPCS, yet it is not clear how often treatment for these systems is warranted. OBJECTIVES To explore how often neck and vestibulo-ocular treatment is received or recommended in people with PPCS. DESIGN Retrospective chart review. METHOD De-identified clinical service data for the calendar year of 2017 were extracted from a single concussion service provider in Dunedin, New Zealand. A summary of the individual assessments and treatments received were extracted and used to determine how often cases were considered to require physician or neuropsychological assessment; and how often cases received or were recommended neck and/or vestibulo-ocular physiotherapy treatment. RESULTS/FINDINGS 147 cases were included in this study. Physician assessment was considered required in 25 cases (17%), and neuropsychological assessment in 90 cases (61%). For physiotherapy, neck treatment was received or recommended in 80 cases (54%), and vestibulo-ocular treatment in 106 cases (72%). Notably, this included 59 cases (40%) where both neck and vestibulo-ocular treatment were received or recommended. CONCLUSIONS The high proportion of cases receiving or recommended neck and vestibulo-ocular treatment strongly suggests both these systems often contribute to PPCS, often in overlap. While based on retrospective data, these findings highlight the value of routine neck and vestibulo-ocular examination in the assessment and management of PPCS. Further prospective study would be beneficial to explore these proportions in more detail and in other regions.

Abstract
CONTEXT Aerobic exercise interventions are increasingly being prescribed for concussion rehabilitation, but whether aerobic training protocols influence clinical concussion diagnosis and management assessments is unknown. OBJECTIVE To investigate the effects of a brief aerobic exercise intervention on clinical concussion outcomes in healthy, active participants. DESIGN Randomized controlled clinical trial. SETTING Laboratory. PATIENTS OR OTHER PARTICIPANTS Healthy (uninjured) participants (n = 40) who exercised ≥3 times/week. INTERVENTION(S) Participants were randomized into the acute concussion therapy intervention (ACTIVE) training or nontraining group. All participants completed symptom, cognitive, balance, and vision assessments during 2 test sessions approximately 14 days apart. Participants randomized to ACTIVE training completed six 30-minute exercise sessions that progressed from 60% to 80% of individualized maximal oxygen consumption (V˙o2max) across test sessions, while the nontraining group received no intervention. MAIN OUTCOME MEASURE(S) The CNS Vital Signs standardized scores, Vestibular/Ocular Motor Screening near-point convergence distance (cm), and Graded Symptom Checklist, Balance Error Scoring System, and Standardized Assessment of Concussion total scores. RESULTS An interaction effect was found for total symptom score ( P = .01); the intervention group had improved symptom scores between sessions (session 1: 5.1 ± 5.8; session 2: 1.9 ± 3.6). Cognitive flexibility, executive functioning, reasoning, and total symptom score outcomes were better but composite memory, verbal memory, and near-point convergence distance scores were worse at the second session (all P values < .05). However, few changes exceeded the 80% reliable change indices calculated for this study, and effect sizes were generally small to negligible. CONCLUSIONS A brief aerobic training protocol had few meaningful effects on clinical concussion assessment in healthy participants, suggesting that current concussion-diagnostic and -assessment tools remain clinically stable in response to aerobic exercise training. This provides normative data for future researchers, who should further evaluate the effect of ACTIVE training on clinical outcomes among concussed populations.

Abstract
BACKGROUND Equestrian riding is a sport with a high risk of concussion. Currently, the literature guiding rehabilitation for concussions in equestrian athletes is limited, especially for directing return to sport. CASE DESCRIPTION In this case report, a 14-year-old female equestrian athlete presented to physical therapy following her third concussion in 3 years. Her primary complaints were headaches, dizziness, difficulty concentrating, light sensitivity, and neck pain. On examination, the patient demonstrated reproduction of symptoms during testing of the vestibular-ocular reflex, showed a 3-line symptomatic loss on the dynamic visual acuity test, and had impairments in the joint position error test (1/5 correct on the left, 4/5 correct on the right) and a Balance Error Scoring System (BESS) score of 38/60 errors. A return-to-riding protocol was adapted from general return-to-sport guidelines and tailored to meet the unique demands of the patient's equestrian sport. The protocol included phased progression through no activity, light aerobic activity, moderate aerobic activity, sport-specific nonjumping skills, sport-specific jumping skills, full practice, and return to competition. During the protocol, the patient participated in 8 physical therapy sessions over 4 weeks for vestibular training, aerobic conditioning, and cervical and core exercises, as well as equestrian exercises at her stables. OUTCOMES At the final evaluation, the patient reported no symptoms at rest, with exercise, or when testing vestibular-ocular reflex. Improvements were noted in the dynamic visual acuity test, joint position error, and BESS, with changes in the BESS exceeding minimal detectable change. The patient completed the full return-to-riding protocol in 8 weeks and was able to return to equestrian competition without complaints. DISCUSSION This case report describes the physical therapy management of an adapted return-to-sport protocol for an equestrian athlete with a history of multiple sport-related concussions.
