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

Brain changes: aerobic exercise for traumatic brain injury rehabilitation

Introduction

Traumatic Brain Injury (TBI) accounts for millions of hospitalizations and deaths worldwide. Aerobic exercise is an easily implementable, non-pharmacological intervention to treat TBI, however, there are no clear guidelines for how to best implement aerobic exercise treatment for TBI survivors across age and injury severity.

Methods

We conducted a PRISMA-ScR to examine research on exercise interventions following TBI in children, youth and adults, spanning mild to severe TBI. Three electronic databases (PubMed, PsycInfo, and Web of Science) were searched systematically by two authors, using keywords delineated from "Traumatic Brain Injury," "Aerobic Exercise," and "Intervention."

Results

Of the 415 papers originally identified from the search terms, 54 papers met the inclusion criteria and were included in this review. The papers were first grouped by participants' injury severity, and subdivided based on age at intervention, and time since injury where appropriate.

Discussion

Aerobic exercise is a promising intervention for adolescent and adult TBI survivors, regardless of injury severity. However, research examining the benefits of post-injury aerobic exercise for children and older adults is lacking.

The Additive Benefits of Aerobic Exercise and Cognitive Training Postconcussion: Current Clinical Concepts

Concussion induces the rapid onset of a short-lived neurophysiological disturbance that often results in autonomic nervous system dysfunction. This dysfunction affects both cardiovascular functioning and higher cognitive processing, inducing postconcussion clinical symptoms (somatic, cognitive, or emotional or a combination) and functional disturbances (impaired balance, cognition, and visual-vestibular performance). Current concussion rehabilitation paradigms using aerobic exercise may improve concussion symptoms. Additionally, cognitive training-focused rehabilitation interventions may enhance cognitive function postinjury. Though aerobic exercise and cognitive training-based concussion rehabilitation are successful independently, the multifaceted nature of concussion suggests the potential benefit of integrating both to improve concussion outcomes and clinician implementation. To support this clinical recommendation, we critiqued the existing research in which authors investigated aerobic exercise and cognitive training as postconcussion rehabilitation modalities, identified keys gaps in the literature, and proposed a practical clinical recommendation to integrate both modalities during concussion rehabilitation.

The Effectiveness of Physical Therapy Interventions for Athletes Post-Concussion: A Systematic Review

Background

Sports-related concussions are the most common cause of head injury in adolescents and young adults. Typical treatment methods for this injury include cognitive and physical rest. Evidence suggests that physical activity and physical therapy interventions can be beneficial to decrease post-concussion symptoms.

Purpose

The aim of this systematic review was to investigate the effectiveness of physical therapy interventions for adolescent and young adult athletes post-concussion.

Study Design

Systematic Review.

Methods

The following databases were utilized for the search: PubMed, CINAHL, Proquest, MEDLINE, SPORTDiscus, and SCOPUS. The search strategy focused on athletes, concussions, and physical therapy interventions. Data extraction from each article included: Authors, subjects, gender, mean age, age range, specific sport, acute or chronic concussion, first or recurrent concussion, treatments for intervention and control group, and outcomes measured.

Results

Eight studies met the inclusion criteria. Six of the eight articles scored seven or higher on the PEDro Scale. Physical therapy intervention(s), such as an aerobic intervention or a multimodal approach, show improvements in time to recovery and reduction of post-concussion symptoms in patients who have had a concussion. Physical activity and physical therapy as early as a couple days following injury, is beneficial at decreasing post-concussion symptoms, allows for earlier return to play, and/or shorter days to recovery, and is considered safe for treating post-concussion symptoms.

Conclusion

This systematic review demonstrates that physical therapy interventions including aerobic exercise and multimodal approaches have been found to be beneficial in treating adolescent and young adult athletes post-concussion. Utilizing aerobic or multimodal interventions for this population allows for a quicker symptom recovery and return to sport than traditional treatment of physical and cognitive rest. Future research should investigate the superior intervention for adolescents and young adults with post-concussion syndrome and determine if a single treatment or a multimodal approach is more beneficial.

Tele-Active Rehabilitation for Youth With Concussion: Evidence-Based and Theory-Informed Intervention Development

BACKGROUND

Active rehabilitation involving subsymptom threshold exercise combined with education and support promotes recovery in youth with concussion but is typically delivered in person, which may limit accessibility for families because of a lack of services in their communities or logistical challenges to attending in-person sessions.

OBJECTIVE

This paper describes the evidence-based and theory-informed development of the Tele-Active Rehabilitation (Tele-AR) intervention for pediatric concussion, which was specifically designed for remote service delivery.

METHODS

The intervention was designed by clinician-researchers with experience in pediatric concussion rehabilitation following the Medical Research Council guidance for developing complex interventions. Development involved a critical review of the literature to identify existing evidence, the expansion of the theoretical basis for active rehabilitation, and the modeling of the intervention process and outcomes.

RESULTS

Tele-AR is a 6-week home exercise and education and support program facilitated through weekly videoconferencing appointments with a clinician. Exercise consists of low- to moderate-intensity subsymptom threshold aerobic activity and coordination drills that are individualized to participant needs and interests (prescribed for 3 days per week). Education includes the evidence-supported Concussion & You self-management program, which covers topics related to energy management, nutrition, hydration, sleep hygiene, and return to activity. Elements of self-determination theory are incorporated to support motivation and engagement. We present a logic model describing predicted intervention effects using a biopsychosocial conceptualization of outcomes after concussion.

CONCLUSIONS

The Tele-AR intervention may help to increase access to care that improves recovery and promotes a timely return to activity in youth with concussion. Future research is needed to evaluate the feasibility and efficacy of this approach.

Tele-Active Rehabilitation for adolescents with concussion: a feasibility study

Objectives

Active rehabilitation involving subsymptom threshold exercise and education/support promotes recovery among adolescents with concussion, but is typically delivered in-person, which limits accessibility. This study explored the feasibility of a remotely delivered Tele-Active Rehabilitation (Tele-AR) intervention for adolescents with concussion.

Methods

A precase–postcase series design was used. Three adolescents (ages 14–17 years) experiencing postconcussion symptoms ≥2 weeks postinjury participated with a parent. The Tele-AR intervention was a 6-week programme supervised by a rehabilitation clinician through weekly videoconferencing appointments and included (1) aerobic exercise, (2) coordination drills and (3) comprehensive education and support. Feasibility indicators included rates of recruitment, retention, adherence, as well as adolescent and parent ratings of technology usability using an adapted Telehealth Usability Questionnaire and satisfaction using the Client Satisfaction Questionnaire-8. Prechanges to postchanges in postconcussion symptoms, illness perceptions, and occupational performance and satisfaction were also assessed.

Results

Rates of recruitment (n=3/4) and retention (n=3/3) achieved success criteria. Adherence was high among all participants (77%–100%), and there were no adverse events. Participant ratings of technology usability and satisfaction approached 90%. All participants reported improvements in postconcussion symptoms and illness perception. Clinically significant positive changes were also observed in occupational performance and satisfaction.

Conclusions

The Tele-AR intervention appears feasible in a small group of adolescents with concussion, and positive changes were observed in postconcussion symptoms, illness perception and occupational performance. Further study is warranted to evaluate the efficacy of this approach, which may enable access to care that supports recovery in adolescents with concussion.

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.
