Concussion Management Practices for Youth Who Are Slow to Recover: A Survey of Canadian Rehabilitation Clinicians.

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.

Objectif : évaluer la portée des pratiques de prise en charge des commotions qu'utilisent les cliniciens canadiens en réadaptation auprès des adolescents. Un objectif secondaire consistait à déterminer l'utilisation de l'exercice aérobique dans les stratégies de prise en charge. Méthodologie : les membres de l'Association canadienne des ergothérapeutes, de l'Association canadienne des thérapeutes du sport et de l'Association canadienne de physiothérapie ont été invités à participer à un sondage transversal en ligne. Ils ont reçu deux scénarios cliniques accompagnés d'une brève histoire. Les répondants ont été invités à indiquer le type de traitements qu'ils prodigueraient (p. ex., thérapie manuelle, éducation, exercice aérobique, protocole de retour à l'apprentissage ou au jeu, établissement d'objectifs, etc.). Résultats : au total, 555 cliniciens ont rempli le sondage. L'éducation, les recommandations au sujet du sommeil, l'établissement d'objectifs, la gestion de l'énergie et la thérapie manuelle étaient les cinq principales options thérapeutiques. Un peu plus du tiers des cliniciens auraient prescrit l'exercice aérobique. Une forte charge de patients victimes d'une commotion (75 % à 100 %) était un prédicteur important de prescription d'exercice aérobique. Conclusion : les répondants ont sélectionné un vaste éventail d'options thérapeutiques, mais les plus courants étaient l'éducation, les recommandations au sujet du sommeil, la gestion de l'énergie et l'établissement d'objectifs. Peu de cliniciens intégraient l'exercice aérobique à leur stratégie de prise en charge des commotions.

Feasibility of Early Active Rehabilitation for Concussion Recovery in Youth: A Randomized Trial.

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.

The Effects of Mild Traumatic Brain Injury on Cognitive-Motor Integration for Skilled Performance.

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

Non-pharmacological rehabilitation interventions for concussion in children: a scoping review.

PURPOSE: To summarise the extent, nature, and quality of current scholarly literature related to non-pharmacological, rehabilitation interventions following concussion, or mild traumatic brain injury in children. METHODS: An electronic search was conducted from 1987 to 24 October 2017. Studies were included if they met the following criteria: (1) full text, peer reviewed, and written in English, (2) original research, (3) diagnosed concussion or mild traumatic brain injury, (4) described the evaluation of an intervention, (5) the outcome was a concussion impairment, and (6) the mean/median age was under 19. Quality assessment using the Down's and Black criteria was conducted. RESULTS: Twenty-six studies published between 2001 and 2017 were identified. Interventions included rest, active rehabilitation, exercise, vestibular, oculomotor, cervicospinal therapy, education, early intervention, telephone counselling, mobile health application, Web-based Self-Management program, multimodal physical therapy, cognitive behavioural therapy, transcranial direct current stimulation, and acupuncture. The quality assessments ranged from poor to good. CONCLUSIONS: The literature describing interventions following concussion in children is scarce. While both positive and negative results were obtained, there were methodological concerns in most studies limiting the ability to draw conclusions. Interventions incorporating aerobic exercise show promise as a concussion management strategy. Implications for rehabilitation Few studies have examined rehabilitation interventions for youth following concussion. Research ranging from rest to exercise highlights the uncertainty of the field. Low quality research limits the generalizability of results. The use of physical activity appears to be an emerging area of interest. Individualised, aerobic exercise should be used as part of clinical management.

Is There an Optimal Time to Initiate an Active Rehabilitation Protocol for Concussion Management in Children? A Case Series.

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.

Physiological and Performance Measures for Baseline Concussion Assessment.

CONTEXT: Baseline testing is a common strategy for concussion assessment and management. Research continues to evaluate novel measures for potential to improve baseline testing methods. OBJECTIVES: The primary objective was to (1) determine the feasibility of including physiological, neuromuscular, and mood measures as part of baseline concussion testing protocol, (2) describe typical values in a varsity athlete sample, and (3) estimate the influence of concussion history on these baseline measures. DESIGN: Prospective observational study. SETTING: Ryerson University Athletic Therapy Clinic. PARTICIPANTS: One hundred varsity athletes. MAIN OUTCOME MEASURES: Frequency and domain measures of heart rate variability, blood pressure, grip strength, profile of mood states-short form, and the Sport Concussion Assessment Tool-2. RESULTS: Physiological, neuromuscular performance, and mood measures were feasible at baseline. Participants with a history of 2 or more previous concussions displayed significantly higher diastolic blood pressure. Females reported higher total mood disturbance compared with males. CONCLUSIONS: Physiological and neuromuscular performance measures are safe and feasible as baseline concussion assessment outcomes. History of concussion may have an influence on diastolic blood pressure.

Evaluation of an active rehabilitation program for concussion management in children and adolescents.

OBJECTIVE: To estimate the extent to which post-concussion symptoms were influenced by participation in an Active Rehabilitation (AR) program (aerobic exercise, coordination drills, visualization and education) for children and adolescents who are slow to recover from concussion. A secondary exploratory objective included examining the influence of sex on symptom evolution. METHODS: Analysis of prospectively collected data was performed on 277 youth who initiated an AR program, between three and four weeks post-injury at a Concussion Clinic in a tertiary care paediatric teaching hospital. MAIN OUTCOME MEASURE: Post-concussion symptom scale (PCSS) from Sport Concussion Assessment Tool-3 (SCAT 3). RESULTS: Children and adolescents participating in an active rehabilitation program displayed improved post-concussion symptom severity at follow-up (median = 9.5) compared to pre-intervention (median = 18) (p < .05). Patients demonstrated improved physical, cognitive, emotional and sleep-related post-concussion symptoms (p < .05). Female sex was associated with an increased post-concussion symptom severity at follow-up. CONCLUSIONS: Youth experiencing persisting symptoms three to four weeks post-concussion demonstrated improved post-concussion symptoms scores (physical, cognitive, emotional and sleep related) with participation in an active rehabilitation program.

A multi-modal approach to assessing recovery in youth athletes following concussion.

Concussion is one of the most commonly reported injuries amongst children and youth involved in sport participation. Following a concussion, youth can experience a range of short and long term neurobehavioral symptoms (somatic, cognitive and emotional/behavioral) that can have a significant impact on one's participation in daily activities and pursuits of interest (e.g., school, sports, work, family/social life, etc.). Despite this, there remains a paucity in clinically driven research aimed specifically at exploring concussion within the youth sport population, and more specifically, multi-modal approaches to measuring recovery. This article provides an overview of a novel and multi-modal approach to measuring recovery amongst youth athletes following concussion. The presented approach involves the use of both pre-injury/baseline testing and post-injury/follow-up testing to assess performance across a wide variety of domains (post-concussion symptoms, cognition, balance, strength, agility/motor skills and resting state heart rate variability). The goal of this research is to gain a more objective and accurate understanding of recovery following concussion in youth athletes (ages 10-18 years). Findings from this research can help to inform the development and use of improved approaches to concussion management and rehabilitation specific to the youth sport community.
