Service Delivery Models for the Management of Pediatric and Adolescent Concussion: A Systematic Review.

Objective: To examine the current peer-reviewed literature on pediatric concussion and mild traumatic brain injury (mTBI) service delivery models (SDMs) and relevant cost analyses. Data Sources: PubMed, Embase (Elsevier), CINAHL Plus (EBSCO), APA PsycINFO (EBSCO), and Web of Science Core Collection, limited to human trials published in English from January 1, 2001, to January 10, 2022. Study Selection: Included articles that (1) were peer-reviewed; (2) were evidence-based; (3) described service delivery and/or associated health care costs; and (4) focused on mTBI, concussion, or postconcussion symptoms of children and adolescents. Studies describing emergency department-based interventions, adults, and moderate to severe brain injuries were excluded. Data Extraction: The initial search resulted in 1668 articles. Using Rayyan software, 2 reviewers independently completed title and abstract screening followed by a full-text screening of potentially included articles. A third blinded reviewer resolved inclusion/exclusion conflicts among the other reviewers. This resulted in 28 articles included. Data Synthesis: Each of the 28 articles were grouped into 1 of the following 3 categories: generalist-based services (7), specialist-based services (12), and web/telemedicine services (6). One article discussed both generalists and specialists. It was clear that specialists are more proactive in their treatment of concussion than generalists. Most of the research on generalists emphasized the need for education and training. Four studies discussed costs relevant to SDMs. Conclusions: This review highlights the need for more discussion and formalized evaluation of SDMs to better understand concussion management. Overall there is more literature on specialist-based services than generalist-based services. Specialists and generalists have overarching similarities but differ often in their approach to pediatric concussion management. Cost analysis data are sparse and more research is needed.

Somatization in Adolescents With Persistent Symptoms After Concussion: A Retrospective Chart Review.

OBJECTIVE: After concussion, approximately 30% of adolescents experience symptoms that persist beyond 1 month postinjury. For some, these symptoms affect functioning, development, and quality of life. Somatization, where psychological distress contributes to physical symptoms, may contribute to persistent symptoms after concussion in some adolescents. Understanding how clinicians identify somatization in adolescents with persistent symptoms after concussion in practice is a critical next step in improving our understanding, identification, and subsequent treatment of somatization in this patient population. To address this, the investigators assessed and compared characteristics of adolescents with persistent symptoms after concussion with and without clinician-identified somatization. METHODS: Participants were adolescents (N=94) referred for persistent symptoms after concussion to a specialty youth concussion clinic between January 2016 and May 2018. A retrospective chart review extracted demographic and injury characteristics, symptoms after concussion, school attendance, premorbid experiences, mental health, and medical service use. Participants with physician-identified somatization were compared with those without physician-identified somatization on these measures. RESULTS: Adolescents with identified somatization had more severe and atypical neurological and psychiatric symptoms after concussion and more postinjury impairment in school attendance, were more likely to have a history of premorbid chronic pain or medically unexplained symptoms, and obtained more neuroimaging and health care after injury compared with those unaffected by somatization. They did not differ in mood or anxiety symptom self-reports. CONCLUSIONS: This study identified characteristic differences and similarities in adolescents with and without clinician-identified somatization after a prolonged concussion recovery. These findings have the potential to improve clinical identification of somatization in youths following a concussion and may aid in treatment among this demographic group.

Safety of Active Rehabilitation for Persistent Symptoms After Pediatric Sport-Related Concussion: A Randomized Controlled Trial.

OBJECTIVES: To examine the safety and tolerability of an active rehabilitation program for adolescents who are slow to recover from a sport-related concussion, and secondarily to estimate the treatment effect for this intervention. DESIGN: Single-site, parallel, open-label, randomized controlled trial comparing treatment as usual (TAU) to TAU plus active rehabilitation. SETTING: Outpatient concussion clinic. PARTICIPANTS: Adolescents (N=19) aged 12 to 18 years with postconcussion symptoms lasting ≥1 month after a sports-related concussion. INTERVENTIONS: TAU consisted of symptom management and return-to-play advice, return-to-school facilitation, and physiatry consultation. The active rehabilitation program involved in-clinic subsymptom threshold aerobic training, coordination exercises, and visualization and imagery techniques with a physiotherapist (mean, 3.4 sessions) as well as a home exercise program, over 6 weeks. MAIN OUTCOME MEASURES: A blinded assessor systematically monitored for predetermined adverse events in weekly telephone calls over the 6-week intervention period. The treating physiotherapist also recorded in-clinic symptom exacerbations during aerobic training. The Post-Concussion Symptom Scale was the primary efficacy outcome. RESULTS: Nineteen participants were randomized, and none dropped out of the study. Of the 12 adverse events detected (6 in each group), 10 were symptom exacerbations from 1 weekly telephone assessment to the next, and 2 were emergency department visits. Four adverse events were referred to an external safety committee and deemed unrelated to the study procedures. In-clinic symptom exacerbations occurred in 30% (9/30) of aerobic training sessions, but resolved within 24 hours in all instances. In linear mixed modeling, active rehabilitation was associated with a greater reduction on the Post-Concussion Symptom Scale than TAU only. CONCLUSIONS: The results support the safety, tolerability, and potential efficacy of active rehabilitation for adolescents with persistent postconcussion symptoms.

Canadian stroke best practice recommendations: Stroke rehabilitation practice guidelines, update 2015.

Stroke rehabilitation is a progressive, dynamic, goal-orientated process aimed at enabling a person with impairment to reach their optimal physical, cognitive, emotional, communicative, social and/or functional activity level. After a stroke, patients often continue to require rehabilitation for persistent deficits related to spasticity, upper and lower extremity dysfunction, shoulder and central pain, mobility/gait, dysphagia, vision, and communication. Each year in Canada 62,000 people experience a stroke. Among stroke survivors, over 6500 individuals access in-patient stroke rehabilitation and stay a median of 30 days (inter-quartile range 19 to 45 days). The 2015 update of the Canadian Stroke Best Practice Recommendations: Stroke Rehabilitation Practice Guidelines is a comprehensive summary of current evidence-based recommendations for all members of multidisciplinary teams working in a range of settings, who provide care to patients following stroke. These recommendations have been developed to address both the organization of stroke rehabilitation within a system of care (i.e., Initial Rehabilitation Assessment; Stroke Rehabilitation Units; Stroke Rehabilitation Teams; Delivery; Outpatient and Community-Based Rehabilitation), and specific interventions and management in stroke recovery and direct clinical care (i.e., Upper Extremity Dysfunction; Lower Extremity Dysfunction; Dysphagia and Malnutrition; Visual-Perceptual Deficits; Central Pain; Communication; Life Roles). In addition, stroke happens at any age, and therefore a new section has been added to the 2015 update to highlight components of stroke rehabilitation for children who have experienced a stroke, either prenatally, as a newborn, or during childhood. All recommendations have been assigned a level of evidence which reflects the strength and quality of current research evidence available to support the recommendation. The updated Rehabilitation Clinical Practice Guidelines feature several additions that reflect new research areas and stronger evidence for already existing recommendations. It is anticipated that these guidelines will provide direction and standardization for patients, families/caregiver(s), and clinicians within Canada and internationally.

Impact of Early Follow-Up Intervention on Parent-Reported Postconcussion Pediatric Symptoms: A Feasibility Study.

OBJECTIVES: To investigate the effectiveness and feasibility of early intervention telephone counseling with parents in limiting postconcussion symptoms and impacts on children and youth. SETTING: Recruitment occurred postdischarge from one pediatric emergency department. PARTICIPANTS: Sixty-six parents of children aged 5 to 16 years with a diagnosis of a concussion injury. DESIGN: A pilot, randomized controlled study compared the efficacy of telephone counseling (reviewing symptom management and return to activity with parents at 1 week and 1 month postinjury) with usual care (no formalized follow-up). MAIN MEASURES: The Post-Concussion Symptom Inventory and the Family Burden of Injury Interview administered with parents by a blinded therapist at 3 months postinjury. RESULTS: No significant difference between the groups at 3 months postinjury in postconcussion symptoms (P = .67) and family stress (P = .647). CONCLUSION: The findings suggest that the early counseling intervention strategy trialed herein may not be effective for children and youth who experience significant postconcussion symptoms. Further research is needed to determine whether more intensive and integrated care would better serve children.

Deep brain stimulation and dantrolene for secondary dystonia in x-linked adrenoleukodystrophy.

Deep brain stimulation (DBS) has been used to treat secondary dystonias caused by inborn errors of metabolism with varying degrees of effectiveness. Here we report for the first time the application of DBS as treatment for secondary dystonia in a 22-year-old male with X-linked adrenoleukodystrophy (X-ALD). The disease manifested at age 6 with ADHD, tics, and dystonic gait, and deteriorated to loss of ambulation by age 11, and speech difficulties, seizures, and characteristic adrenal insufficiency by age 16. DBS in the globus pallidus internus was commenced at age 18. However, after 25 months, no improvement in dystonia was observed (Burke-Fahn-Marsden (BFM) scores of 65.5 and 62 and disability scores of 28 and 26, pre- and post-DBS, respectively) and the DBS device was removed. Treatment with dantrolene reduced skeletal muscle tone and improved movement (Global Dystonia Rating Scores from 5 to 1 and BFM score 42). Therefore, we conclude that DBS was a safe but ineffective intervention in our case with long-standing dystonia, whereas treatment of spasticity with dantrolene did improve the movement disorder in this young man with X-ALD.
