RESUMEN
OBJECTIVE: To assess demographic, clinical, and injury characteristics associated with health-related quality of life (HRQOL) in adults with persistent post-concussion symptoms (PPCS). METHODS: Adults with PPCS presenting to a specialized brain injury clinic completed demographic, injury, and clinical outcome questionnaires at the initial clinic assessment. Clinical outcome measures were collected including the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and the Fatigue Severity Scale (FSS). HRQOL was measured using the Quality of Life after Brain Injury (QOLIBRI) questionnaire. Stepwise hierarchical multiple regression analysis adjusting for age, sex, and months since injury was used to determine associations between quality of life and clinical outcome measures. RESULTS: Overall, 125 participants were included. The PHQ-9, FSS, and GAD-7 were significant predictors of QOLIBRI scores (R2 = 0.481, p < .001), indicating that participants with higher levels of depressive symptoms, fatigue, and anxiety reported poorer HRQOL. The PHQ-9 score was the strongest predictor, accounting for 42.0% of the variance in QOLIBRI scores. No demographic or injury characteristics significantly predicted QOLIBRI scores. There was a high prevalence of depressive symptoms with 72.8% of participants having PHQ-9 scores ≥ 10. CONCLUSION: Among patients with PPCS, mental health and fatigue are important contributors to HRQOL. As there is a high burden of mood disorders and fatigue in this population, targeted treatments for these concerns may impact the quality of life.

OBJECTIVE: To evaluate physical activity (PA) and sedentary behavior and their associations with symptom and quality of life outcomes in adults with persistent postconcussive symptoms (PPCS) after mild traumatic brain injury (mTBI). DESIGN: Cross-sectional cohort study. SETTING: Outpatient brain injury clinic. PARTICIPANTS: Consecutive sample of adults (N=180) with a diagnosis of mTBI and PPCS. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: PA and sedentary behavior were assessed using the Godin Leisure-Time Exercise Questionnaire and Rapid Assessment Disuse Index, respectively. Participants were dichotomized according to whether they completed 150 minutes of moderate-to-vigorous PA per week, based on Canadian guidelines. Postinjury moderate-to-vigorous PA was also analyzed as a continuous variable. RESULTS: Prior to injury, 85% of participants reported meeting PA guidelines, compared with 28% postinjury. Individuals meeting PA guidelines postinjury reported higher quality of life (η2p=0.130; P<.001) and lower scores on measures of functional impact of headache (η2p=0.065; P=.009), fatigue (η2p=0.080; P=.004), depression (η2p=0.085; P=.001), and anxiety (η2p=0.046; P=.031), compared with those not meeting guidelines. Sedentary behavior postinjury was negatively correlated with quality of life (rs[127]=-0.252; P=.004) and positively correlated with symptom burden (rs[167]=0.227; P=.003), fatigue (rs[127]=0.288; P=.001), depression (rs[174]=0.319; P<.001), and anxiety (rs[127]=0.180; P=.042). CONCLUSIONS: PA was significantly decreased in individuals with PPCS compared to preinjury levels. Meeting PA guidelines postinjury was associated with better clinical outcomes, suggesting that returning individuals to PA should be considered in the treatment of this patient population.

BACKGROUND: Persistent post-concussive symptoms (PPCS) affect up to 30% of individuals following mild traumatic brain injury. PPCS frequently includes exercise intolerance. Sub-symptom threshold aerobic exercise has been proposed as a treatment option for symptom burden and exercise intolerance in this population. The primary aim of this study is to evaluate whether a progressive, sub-symptom threshold aerobic exercise program can alleviate symptom burden in adults with PPCS. METHODS: Fifty-six adults (18-65) with PPCS (>3mos-5 yrs) will be randomized into two groups: an immediate start 12-week aerobic exercise protocol (AEP) or delayed start 6-week placebo-like stretching protocol (SP), followed by AEP. Aerobic or stretching activities will be completed 5x/week for 30 mins during the intervention. Online daily activity logs will be submitted. Exercise prescriptions for the AEP will be 70-80% of heart rate at the point of symptom exacerbation achieved on a treadmill test with heart rate monitoring. Exercise prescription will be updated every 3-weeks with a repeat treadmill test. The Rivermead Post-concussion Symptom Questionnaire will be the primary outcome measure at 6 and 12-weeks of intervention. Secondary outcomes include assessments of specific symptoms (headache, quality of life, mood, anxiety, fatigue, dizziness, sleep parameters, daytime sleepiness) in addition to blood biomarkers and magnetic resonance imaging and spectroscopy data for quantification of brain metabolites including γ-aminobutyric acid (GABA), glutathione, glutamate and N-acetyl aspartate (NAA) all measured at 6 and 12-weeks of intervention. DISCUSSION: This trial will evaluate the use of aerobic exercise as an intervention for adults with PPCS, thus expanding our knowledge of this treatment option previously studied predominantly for adolescent sport-related concussion. TRIAL REGISTRATION: ClinicalTrials.gov - NCT03895450 (registered 2019-Feb-11).

PURPOSE: Explore facilitators and barriers to development and integration of an inpatient music therapy (MT) program from the perspective of the patient, family member, and health care professional. MATERIALS AND METHODS: This qualitative study recruited patients on acute neurosciences/neurorehabilitation units having participated in the hospital MT program, their family, and members of their health care team. Semi-structured individual interviews and focus groups were conducted with 35 participants (14 patients, 5 family members, 16 health care professionals). Interviews/focus groups were audio recorded and transcribed verbatim. Data were coded in duplicate and a codebook was developed through an iterative process. RESULTS: Four dominant themes emerged from the data: (1) facilitators of program operations; (2) barriers to program establishment; (3) perceived positive impact on patient outcomes; and (4) opportunity for improvement. Facilitator sub-themes included a love for music that encouraged participation, broad appeal of MT, and support of the health care team. CONCLUSIONS: Patients, health care professionals, and family members accepted MT as a treatment modality. While there is growing evidence for MT in neurorehabilitation, practical challenges remain in developing inpatient MT services, including funding, and optimal integration of music therapists into existing care teams.
Music therapy (MT) is a therapy modality that can be used to target breath control, speech, motor control, and emotional regulation goals in neurorehabilitation.Development of an MT program was facilitated by the broad appeal of the therapy and support from the health care team.Multi-pronged education efforts are needed to increase staff awareness of specific indications and benefits of MT.MT sessions should be offered more than once per week on neurorehabilitation units.
RESUMEN
BACKGROUND AND PURPOSE: It is estimated that 18-30% of concussion sufferers experience symptoms lasting more than 1 month, known as persistent post-concussion symptoms (PPCS). Symptoms can be debilitating, and include headache, dizziness, nausea, problems with memory and concentration, sleep and mood disruption, and exercise intolerance. Previous studies have used quantitative susceptibility mapping (QSM) to show altered tissue susceptibility levels in adults acutely following concussion, however this finding has yet to be investigated in participants with PPCS. MATERIALS AND METHODS: In this exploratory case-controlled study, we measured tissue susceptibility using quantitative susceptibility mapping (QSM) in 24 participants with PPCS following mild traumatic brain injury (mTBI) and 23 healthy controls with no history of concussion. We compute tissue susceptibility for seven white matter tracts and three deep grey matter regions and compare tissue susceptibility between groups using ANCOVA models controlling for age and sex. We also assess the relationship between regional tissue susceptibility and symptoms. RESULTS: There were no significant differences between tissue susceptibility in participants with PPCS compared to control subjects in any of the evaluated regions. However, we show lower tissue susceptibility across four white matter tracts was generally associated with worse symptoms in the PPCS group. Specifically, we saw relationships between white matter susceptibility and headache (p=0.006), time since injury (p=0.03), depressive symptoms (p=0.021) and daytime fatigue (p=0.01) in participants with PPCS. CONCLUSIONS: These results provide evidence in support of persistent changes in the brain months-to-years following injury and highlight the need to further understand the pathophysiology of PPCS, to determine effective prevention and treatment options.

RESUMEN
OBJECTIVES: The primary aim of this study was to characterize sleep in adults with persistent post-concussive symptoms (PPCS). Secondary aims explored relationships between sleep parameters, injury characteristics, and symptom questionnaires. METHODS: This case-controlled, cross-sectional study recruited adults (18-65yrs) diagnosed with PPCS and age and sex-matched controls. Participants wore a wrist-worn actigraph for 3-7 nights and completed daily sleep diaries. Participants completed questionnaires examining daytime sleepiness, fatigue, anxiety/depressive symptoms, and sedentariness. Sleep parameters were compared between groups using Mann-Whitney U tests. Secondary analyses used two-way ANOVA and Spearman's rank correlations. RESULTS: Fifty adults with PPCS (43.7 ± 10.6yrs, 78 % female) and 50 controls (43.6 ± 11.0yrs) were included in this study. Adults with PPCS had significantly longer sleep onset latency (PPCS 16.99 ± 14.51min, Controls 8.87 ± 6.44min, p < 0.001) and total sleep time (PPCS 8.3 ± 1.0hrs, Control 7.6 ± 0.9hrs, p = 0.030) compared to controls, but woke up later (PPCS 7:57:27 ± 1:36:40, Control 7:17:16 ± 0:50:08, p = 0.026) and had poorer sleep efficiency (PPCS 77.9 ± 7.5 %, Control 80.8 ± 6.0 %, p = 0.019) than controls. Adults with PPCS reported more daytime sleepiness (Epworth Sleepiness Scale: PPCS 8.70 ± 4.61, Control 4.28 ± 2.79, p < 0.001) and fatigue (Fatigue Severity Scale: PPCS 56.54 ± 12.92, Control 21.90 ± 10.38, p < 0.001). Injury characteristics did not significantly affect sleep parameters in adults with PPCS. Actigraphy parameters were not significantly correlated to questionnaire measures. CONCLUSION: Several actigraphy sleep parameters were significantly altered in adults with PPCS compared to controls, but did not correlate with sleep questionnaires, suggesting both are useful tools in characterizing sleep in PPCS. Further, this study provides potential treatment targets to improve sleep difficulties in adults with PPCS.

PURPOSE: Spinal cord injury (SCI) has lifelong implications requiring treatment for outcomes including respiratory function, voice, pain, mood, and gait, among others. Music therapy (MT) and music-based interventions may be useful in the treatment of several outcomes. This review describes the use of MT and music-based interventions in individuals with SCI for rehabilitation and health and highlights future research priorities. MATERIALS AND METHODS: MEDLINE, Embase, PsycInfo, CINAHL, RILM, Music Periodicals and Music Index were searched. Search terms included: SCI and music. Studies of cohorts with SCI using music interventions and descriptions of adapted instruments or development of MT programs were included. Abstracts and full texts were reviewed in duplicate. Data were extracted according to clinical outcomes. A structured synthesis was performed. RESULTS: Forty-three studies were included. Research in the field includes quantitative, qualitative and mixed-methods studies. Group singing and an individual songwriting program for self-concept were the most studied interventions. Outcomes varied; mood outcomes were most common. CONCLUSION: While qualitative data support the use of MT and music-based interventions in this population for a wide variety of outcomes, randomized controlled trials are needed. There is a lack of research on the use of individual MT in this population. Registration: osf.io/9m8v4 Implications for RehabilitationIndividuals with spinal cord injury (SCI) often suffer from injury complications and significant medical morbidity requiring practical long-term treatment and wellness strategies.Music therapy (MT) and music-based interventions can be used for many rehabilitation and health goals in this population including mood, gait and respiratory function, among others.Preliminary qualitative and quantitative studies have reported the benefits of MT across a range of outcomes in individuals with SCI; however, additional research, especially evaluating individual MT interventions, is needed.

PURPOSE: Music therapy (MT) has been used in health care settings for a wide variety of treatment goals. Many inpatients with neurologic impairments struggle with low mood and pain for which MT may be a novel adjunct treatment. The aims of this study were to: (1) evaluate change in mood and pain following a single MT session; (2) explore the impact of an MT program on mood, pain and satisfaction from the perspective of the patient, family and staff. MATERIALS AND METHODS: A mixed-methods study was conducted. Forty participants completed pre/post MT surveys evaluating mood, pain and satisfaction. Individual semi-structured interviews and focus groups were conducted with 14 MT program participants (inpatients), 5 family members of participants and 16 staff. RESULTS: There was significant improvement in mood (p < 0.001) and decrease in pain (p < 0.05) from pre-to-post MT with 74% reporting being "very satisfied" with the session. "Benefits of MT" was the overarching theme of the qualitative data. Subthemes were emotional regulation, pain management, effects on self-concept, enjoyment, and social connectedness. CONCLUSIONS: Improvements in mood and pain were reported from pre-to-post MT session and in interviews. Further evaluation of MT effectiveness against standard of care rehabilitation and cost implications is required.Implications for RehabilitationMusic therapy (MT) is delivered by accredited music therapists (MTAs) in health care settings, including rehabilitation units, as an individual, group or co-treatment therapy.MT can be used for a range of health outcomes, including the treatment of mood and pain, in addition to improving inpatient satisfaction.Early evidence using pre/post MT surveys suggests an improvement in mood and pain following a single therapy session.Qualitative data suggest overall benefit of offering MT services in addition to standard neurorehabilitation therapy, including improvements to emotional regulation, pain management, self-concept, enjoyment, and social connectedness.

BACKGROUND: Increasing evidence suggests autonomic nervous system (ANS) dysfunction may occur following mild traumatic brain injury (mTBI). Measures of heart rate, heart rate variability, blood pressure and baroreceptor sensitivity can be used to evaluate ANS dysfunction following mTBI. OBJECTIVE: Summarize the evidence for ANS dysfunction in adults following mTBI. METHODS: A search of Embase, MEDLINE, Cochrane Central Register, PsycINFO, CINAHL and SPORTDiscus databases was conducted. Search topics included: mTBI and ANS. Identified abstracts were independently reviewed by 2 reviewers followed by full text screening. Risk of bias was assessed using a modified SIGN checklist. A structured synthesis was performed. RESULTS: Thirty-nine studies (combined 1,467 participants diagnosed with mTBI) evaluating ANS function were included. ANS function was evaluated under various conditions including: rest, during exertion, cold pressor test, Valsalva maneuver, using face cooling and eyeball pressure paradigms. Short-term or ultra-short-term recordings were most common. The majority of studies (28/39) were rated as "unacceptable" for quality of evidence. CONCLUSIONS: Altered parameters of ANS function have been reported in multiple conditions following mTBI, both acutely and in the post-acute/chronic stages of recovery. However, due to methodological limitations, conclusions regarding the severity and timing of ANS dysfunction following mTBI cannot be drawn.

Persistent post-concussive symptoms (PPCS) are debilitating and endure beyond the usual recovery period after mild traumatic brain injury (mTBI). Altered neurotransmission, impaired energy metabolism and oxidative stress have been examined acutely post-injury but have not been explored extensively in those with persistent symptoms. Specifically, the antioxidant glutathione (GSH) and the excitatory and inhibitory metabolites, glutamate (Glu) and γ-aminobutyric acid (GABA), are seldom studied together in the clinical mTBI literature. While Glu can be measured using conventional magnetic resonance spectroscopy (MRS) methods at 3 Tesla, GABA and GSH require the use of advanced MRS methods. Here, we used the recently established Hadamard Encoding and Reconstruction of MEGA-Edited Spectroscopy (HERMES) to simultaneously measure GSH and GABA and short-echo time point resolved spectroscopy (PRESS) to measure Glu to gain new insight into the pathophysiology of PPCS. Twenty-nine adults with PPCS (mean age: 45.69 years, s.d.: 10.73, 22 females, 7 males) and 29 age- and sex-matched controls (mean age: 43.69 years, s.d.: 11.00) completed magnetic resonance spectroscopy scans with voxels placed in the anterior cingulate and right sensorimotor cortex. Relative to controls, anterior cingulate Glu was significantly reduced in PPCS. Higher anterior cingulate GABA was significantly associated with a higher number of lifetime mTBIs, suggesting GABA may be upregulated with repeated incidence of mTBI. Furthermore, GSH in both regions of interest was positively associated with symptoms of sleepiness and headache burden. Collectively, our findings suggest that the antioxidant defense system is active in participants with PPCS, however this may be at the expense of other glutamatergic functions such as cortical excitation and energy metabolism.

Pituitary dysfunction, specifically growth hormone (GH) deficiency, can occur following traumatic brain injury. Our objective was to characterize the prevalence of GH deficiency (GHD) testing and response to recombinant human GH (rhGH) treatment in adults with persistent symptoms following mild traumatic brain injury (mTBI) referred for assessment of pituitary dysfunction. A retrospective chart review was conducted of patients seen at an outpatient brain injury clinic with a diagnosis of mTBI and persistent post-concussive symptoms who were referred to endocrinology. Clinical assessments of symptoms were collected. Investigations and results of GHD were collected, including initiation of rhGH treatment and treatment response. Of the 253 patients seen in both brain injury and endocrinology clinics, 97 with mTBI were referred for investigation of pituitary dysfunction and 73 (75%) had dynamic testing for assessment of GHD. Of the 26 individuals diagnosed with GHD, 23 (88%) started rhGH. GH therapy was inconsistently offered based on interpretation of GH dynamic testing results. Of those who started rhGH, 18 (78%) had a useful treatment response. This study suggests that clinical management of these patients is varied, highlighting a need for clear guidelines for the diagnosis and management of GHD following mTBI.
