A health and wellness intervention for those with moderate to severe traumatic brain injury: a randomized controlled trial

Therapeutic groups run for community-dwelling people with acquired brain injury: a scoping review

PURPOSE

Therapeutic group interventions are commonly provided in acquired brain injury (ABI) inpatient rehabilitation settings, but little is known about the extent of therapeutic groups run for community-dwellers with ABI. This paper seeks to review current literature concerning the nature of therapeutic groups run for community-dwellers with ABI and the involvement of occupational therapists.

MATERIALS & METHODS

A scoping review was conducted with systematic searching of relevant databases guided by Arksey and O'Malley's framework. Studies were included if they reported on therapeutic groups for community-dwellers with ABI. Articles were collated and summarised with key findings presented in narrative form with accompanying tables.

RESULTS

Seventy articles met inclusion. Groups are used as therapeutic change agents for community-dwellers with ABI and target a diverse range of participation barriers. Participants valued group programs that established safe environments, a sense of belonging, growth opportunities and social connections. Group accessibility needs to be improved, with better funding avenues available for service providers, as well as greater consumer involvement in group design and facilitation.

CONCLUSIONS

Groups are a valuable therapeutic modality supporting community-dwellers with ABI. Further research is warranted into the use of groups by occupational therapists working with community-dwellers with ABI.IMPLICATIONS FOR REHABILITATIONTherapeutic groups can support the development of social connections, community participation and help community-dwellers with ABI re-establish a positive self-identity.Conducting groups in community settings and involving consumers in group design and facilitation may enhance the group experience for participants.Occupational Therapists should be involved in the design and delivery of occupation-based and participation focused group-based programs.

Integrated Care Pathways for Black Persons With Traumatic Brain Injury: A Critical Transdisciplinary Scoping Review of the Clinical Care Journey

Objectives: This novel critical transdisciplinary scoping review examined the literature on integrated care pathways that consider Black people living with traumatic brain injury (TBI). The objectives were to (a) summarize the extent, nature, and range of literature on care pathways that consider Black populations, (b) summarize how Blackness, race, and racism are conceptualized in the literature, (c) determine how Black people come to access care pathways, and (d) identify how care pathways in research consider the mechanism of injury and implications for human occupation. Methods: Six databases were searched systematically identifying 178 articles after removing duplicates. In total, 43 articles on integrated care within the context of Black persons with TBI were included. Narrative synthesis was conducted to analyze the data and was presented as descriptive statistics and as a narrative to tell a story. Findings: All studies were based in the United States where 81% reported racial and ethnic disparities across the care continuum primarily using race as a biological construct. Sex, gender, and race are used as demographic variables where statistical data were stratified in only 9% of studies. Black patients are primarily denied access to care, experience lower rates of protocol treatments, poor quality of care, and lack access to rehabilitation. Racial health disparities are disconnected from racism and are displayed as symptoms of a problem that remains unnamed. Conclusion: The findings illustrate how racism becomes institutionalized in research on TBI care pathways, demonstrating the need to incorporate the voices of Black people, transcend disciplinary boundaries, and adopt an anti-racist lens to research.

More to the story than executive function: Effortful control soon after injury predicts long-term functional and social outcomes following pediatric traumatic brain injury in young children

OBJECTIVE

To examine the impact of early traumatic brain injury (TBI) on effortful control (EC) over time and the relationship of EC and executive functioning (EF) to long-term functional and social outcomes.

METHOD

Parents of children (N = 206, ages 3-7) with moderate-to-severe TBI or orthopedic injuries (OIs) rated EC using the Child Behavior Questionnaire at 1 (pre-injury), 6, 12, and 18 months post-injury. Child functioning and social competence were assessed at 7 years post-injury. Mixed models examined the effects of injury, time since injury, and their interaction on EC. General linear models examined the associations of pre-injury EC and EC at 18 months with long-term functional and social outcomes. Models controlled for EF to assess the unique contribution of EC to outcomes.

RESULTS

Children with severe TBI had significantly lower EC than both the OI and moderate TBI groups at each post-injury time point. Both pre-injury and 18-month EC were associated with long-term outcomes. Among those with low EC at baseline, children with moderate and severe TBI had more functional impairment than those with OI; however, no group differences were noted at high levels of EC. EC had main effects on parent-reported social competence that did not vary by injury type.

CONCLUSIONS

Findings suggest that EC is sensitive to TBI effects and is a unique predictor of functional outcomes, independent of EF. High EC could serve as a protective factor, and as such measures of EC could be used to identify children for more intensive intervention.

Efficacy of the Diabetes Prevention Program Group Lifestyle Balance Program Modified for Individuals with TBI (GLB-TBI): Results from a 12-month Randomized Controlled Trial

BACKGROUND

Obesity after traumatic brain injury (TBI) is a public health issue and no evidence-based weight loss interventions exist to meet the unique needs of individuals after TBI.

PURPOSE

To (a) examine the efficacy of the Diabetes Prevention Program Group Lifestyle Balance for TBI (GLB-TBI) weight-loss intervention compared to an attention control for primary (weight-loss) and secondary health outcomes; (b) determine participant compliance with the GLB-TBI; and (c) determine if compliance is associated with improved outcomes.

METHODS

Individuals with moderate to severe TBI, age 18-64 years, ≥6 months postinjury, and body mass index of ≥25 kg/m2 were randomized to a 12-month, 22-session GLB-TBI intervention or attention control condition. Weight-loss (lbs.), anthropometric, biomarkers, and patient-reported outcomes were collected at baseline, 3, 6, and 12 months.

RESULTS

The GLB-TBI group (n = 27) lost 17.8 ± 41.4lbs (7.9%) over the 12-month program and the attention control group (n = 27) lost 0 ± 55.4lbs (0%). The GLB-TBI group had significant improvements in diastolic blood pressure, triglycerides, and HDL cholesterol. GLB-TBI attendance was 89.6% and weekly self-monitoring of diet and activity was 68.8%. Relative to baseline, the GLB-TBI compliant group (≥80% attendance; ≥85% self-monitoring; n = 10) had a statistically significant decrease in weight at each assessment, the noncompliant group had a significant decrease between 6 and 12 months (n = 17), with no change in weight in the attention control group (n = 27).

CONCLUSIONS

Findings suggest for adults with TBI who are overweight or obese, participation in the GLB-TBI can significantly reduce weight and metabolic risk factors and increase self-reported habits for diet and exercise.

The effect of physical activity on health outcomes in people with moderate-to-severe traumatic brain injury: a rapid systematic review with meta-analysis

BACKGROUND

In 2020, the World Health Organization (WHO) released the first global physical activity and sedentary behaviour guidelines for children and adults living with disability. The evidence informing the guidelines though is not specific to people living with traumatic brain injury (TBI), but rather comes from other disabling conditions such as Parkinson's disease, and stroke. There remains a clear lack of direct evidence of the effects of physical activity for people living with TBI. The objective of this rapid review was to identify direct evidence of the effect of physical activity on health outcomes in people with moderate-to-severe TBI to inform adaptation of the WHO physical activity guidelines into clinical practice guidelines.

METHODS

We conducted a rapid systematic review with meta-analysis of randomised controlled trials, including people of any age with moderate-to-severe TBI, investigating physical activity interventions compared to either usual care, a physical activity intervention with different parameters, or a non-physical activity intervention. Four databases (CENTRAL, SPORTDiscus, PEDro, Ovid MEDLINE) were searched from inception to October 8, 2021. The primary outcomes were physical function, cognition, and quality of life.

RESULTS

Twenty-three studies were included incorporating 812 participants (36% females, majority working-age adults, time post-TBI in studies ranged from 56 days (median) to 16.6 years (mean)). A range of physical activity interventions were evaluated in rehabilitation (n = 12 studies), community (n = 8) and home (n = 3) settings. We pooled data from the end of the intervention for eight outcomes. Participation in a virtual reality physical activity intervention improved mobility, assessed by the Community Balance and Mobility Scale (range 0 to 96; higher score indicates better mobility) more than standard balance training (two studies, 80 participants, Mean Difference = 2.78, 95% CI 1.40 to 4.16; low certainty evidence). There was uncertainty of effect for the remaining outcomes, limited by small sample sizes, diverse comparators and a wide range of outcome measures.

CONCLUSION

This review consolidates the current evidence base for the prescription of physical activity for people with moderate-to-severe TBI. There remains a pressing need for further rigorous research in order to develop practice guidelines to support clinical decision-making when prescribing physical activity in this population.

Effects of cognitive behavioral therapy for adults with post-concussion syndrome: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Although the mechanism of post-concussion syndrome remains unclear, psychological factors are thought to be associated with its development. Cognitive behavioral therapy is the gold standard for psychological disorders; however, its effects on post-concussion syndrome remain unclear. Through this meta-analysis, we assessed the effects of cognitive behavioral therapy on post-concussion syndrome following traumatic brain injury.

METHODS

Six electronic databases were searched from inception to September 15, 2019, for randomized controlled trials evaluating the effects of cognitive behavioral therapy for adults with post-concussion syndrome. Primary outcomes included the severity of symptoms of post-concussion syndrome, depression, anxiety, and social integration. Secondary outcomes were fatigue, cognitive function, and quality of life. Effects were estimated through the calculation of Hedge's g and 95% confidence interval using a random effects model. Sensitivity analyses were conducted by excluding studies in which an intention-to-treat analysis was not employed.

RESULTS

In total, 24 studies were included. Most studies had risk of bias. Significant effects were found for most outcomes, except for severity of symptoms of post-concussion syndrome, fatigue, executive function, and problem solving. After sensitivity analyses, the effects of cognitive behavioral therapy remained significant for immediate and mid-term effects on depression, anxiety, and social integration.

CONCLUSIONS

This study does not support the effectiveness of cognitive behavioral therapy for severity of symptoms of post-concussion syndrome; however, it might be an effective treatment option for improving depression, anxiety, and social integration in individuals with traumatic brain injury.

Randomized Controlled Trials of Rehabilitation Services in the Post-acute Phase of Moderate and Severe Traumatic Brain Injury - A Systematic Review

Background and aims: There is a gap in knowledge regarding effective rehabilitation service delivery in the post-acute phase after traumatic brain injury (TBI). Recently, Gutenbrunner et al. proposed a classification system for health-related rehabilitation services (International Classification System for Service Organization in Health-related Rehabilitation, ICSO-R) that could be useful for contrasting and comparing rehabilitation services. The ICSO-R describes the dimensions of Provision (i.e., context of delivered services), Funding (i.e., sources of income and refunding), and Delivery (i.e., mode, structure and intensity) at the meso-level of services.

We aim to:

-Provide an overview of randomized, controlled trials (RCTs) with rehabilitation service relevance provided to patients with moderate and severe TBI in the post-acute phase using the ICSO-R as a framework; and

-Evaluate the extent to which the provision, funding and delivery dimensions of rehabilitation services were addressed and differed between the intervention arms in these studies.

Materials and methods: A systematic literature search was performed in OVID MEDLINE, EMBASE, CINHAL, PsychINFO, and CENTRAL, including multidisciplinary rehabilitation interventions with RCT designs and service relevance targeting moderate and severe TBI in the post-acute phase.

Results: 23 studies with 4,644 TBI patients were included. More than two-thirds of the studies were conducted in a hospital-based rehabilitation setting. The contrast in Context between the intervention arms often co-varied with Resources. The funding of the services was explicitly described in only one study. Aspects of the Delivery dimension were described in all of the studies, and the Mode of Production, Intensity, Aspects of Time and Peer Support were contrasted in the intervention arms in several of the studies. A wide variety of outcome measures were applied often covering Body function, as well as the Activities and Participation domains of the International Classification of Functioning, Disability, and Health (ICF).

Conclusion: Aspects of service organization and resources as well as delivery may clearly influence outcome of rehabilitation. Presently, lack of uniformity of data and collection methods, the heterogeneity of structures and processes of rehabilitation services, and a lack of common outcome measurements make comparisons between the studies difficult. Standardized descriptions of services by ICSO-R, offer the possibility to improve comparability in the future and thus enhance the relevance of rehabilitation studies.

A randomized controlled trial protocol for people with traumatic brain injury enrolled in a healthy lifestyle program (GLB-TBI)

Weight gain is prevalent among people with traumatic brain injury (TBI) and may be attributable to environmental or injury-specific factors such as mobility impairment, endocrine dysfunction, behavioral and emotional disorders, and sensory loss. Few weight management programs exist to meet the unique needs of this population. Researchers modified a nationally recognized, evidence-based weight-loss program, Group Lifestyle Balance™ (GLB), to address the needs of over-weight and obese people post TBI (GLB-TBI). This current randomized controlled trial (RCT) examines the efficacy of the GLB-TBI on weight and secondary outcomes compared to an attention control educational support group. Furthermore, researchers have developed a mobile technology app to further engage participants in the program. This RCT will enroll and randomize 66 participants over a two-year period. It is anticipated that findings from this current RCT will contribute to the knowledge and evidence for an effective weight-loss intervention among this underserved population, with a goal of achieving full recognition by the Centers for Disease Control and Prevention-National Diabetes Prevention Program and subsequent Center for Medicare and Medicaid Services reimbursement for participation.

Interventions to Address the Needs of Adults With Postconcussion Syndrome: A Systematic Review

Postconcussion syndrome (PCS) affects physical, cognitive, and emotional functioning. Existing reviews of interventions to address PCS are limited to psychological and rehabilitation interventions and to child and adolescent populations. We conducted a systematic review integrating current evidence about interventions for adults with PCS. The inclusion criteria were intervention studies of adults (ages ≥18 yr) with PCS that evaluated recovery from PCS symptoms and focused on functional outcomes; 10 studies met the criteria. Included studies demonstrated medium to high levels of evidence and investigated psychotherapy, counseling, social support, self-management strategies, individualized rehabilitation, hyperbaric oxygen interventions, and group-based cognitive–behavioral therapy. Outcomes included reduced postconcussion symptoms, improved cognitive function, enhanced quality of life, and increased community integration. The evidence supports psychotherapy, counseling, and social support interventions as being beneficial for cognitive and emotional functions in adults with PCS.

A systematic review of the efficacy of self-management programs for increasing physical activity in community-dwelling adults with acquired brain injury (ABI)

BACKGROUND

Individuals living with acquired brain injury, typically caused by stroke or trauma, are far less likely to achieve recommended levels of physical activity for optimal health and well-being. With a growing number of people living with chronic disease and disability globally, self-management programs are seen as integral to the management of these conditions and the prevention of secondary health conditions. However, to date, there has been no systematic review of the literature examining the efficacy of self-management programs specifically on physical activity in individuals with acquired brain injury, whether delivered face-to-face or remotely. Therefore, the purpose of this review is to evaluate the efficacy of self-management programs in increasing physical activity levels in adults living in the community following acquired brain injury. The efficacy of remote versus face-to-face delivery was also examined.

METHODS

A systematic review of the literature was conducted. Electronic databases were searched. Two independent reviewers screened all studies for eligibility, assessed risk of bias, and extracted relevant data.

RESULTS

Five studies met the inclusion criteria for this review. Studies were widely heterogeneous with respect to program content and delivery characteristics and outcomes, although all programs utilized behavioral change principles. Four of the five studies examined interventions in which physical activity was a component of a multifaceted intervention, where the depth to which physical activity specific content was covered, and the extent to which skills were taught and practiced, could not be clearly established. Three studies showed favorable physical activity outcomes following self-management interventions for stroke; however, risk of bias was high, and overall efficacy remains unclear. Although not used in isolation from face-to-face delivery, remote delivery via telephone was the predominant form of delivery in two studies with support for its inclusion in self-management programs for individuals following stroke.

CONCLUSIONS

The efficacy of self-management programs in increasing physical activity levels in community-dwelling adults following acquired brain injury (ABI) is still unknown. Research into the efficacy of self-management programs specifically aimed at improving physical activity in adults living in the community following acquired brain injury is needed. The efficacy of remote delivery methods also warrants further investigation.

Randomized controlled trials in adult traumatic brain injury: a review of compliance to CONSORT statement

OBJECTIVE

To describe the extent to which adherence to Consolidated Standards of Reporting Trials (CONSORT) statement in randomized controlled trials (RCTs) in adult traumatic brain injury (TBI) has improved over time.

DATA SOURCES

MEDLINE, PsycINFO, and CINAHL databases were searched from inception to September 2013.

STUDY SELECTION

Primary report of RCTs in adult TBI. The quality of reporting on CONSORT checklist items was examined and compared over time. Study selection was conducted by 2 researchers independently. Any disagreements were solved by discussion.

DATA EXTRACTION

Two reviewers independently conducted data extraction based on a set of structured data extraction forms. Data regarding the publication years, size, locations, participation centers, intervention types, intervention groups, and CONSORT checklist items were extracted from the including trials.

DATA SYNTHESIS

Of 105 trials reviewed, 38.1%, 5.7%, and 32.4% investigated drugs, surgical procedures, and rehabilitations as the intervention of interest, respectively. Among reports published between the 2 periods 2002 and 2010 (n=51) and 2011 and September 2013 (n=16), the median sample sizes were 99 and 118; 39.2% and 37.5% of all reports detailed implementation of the randomization process; 60.8% and 43.8% provided information on the method of allocation concealment; 56.9% and 31.3% stated how blinding was achieved; 15.7% and 43.8% reported information regarding trial registration; and only 2.0% and 6.3% stated where the full trial protocol could be accessed, all respectively.

CONCLUSIONS

Reporting of several important methodological aspects of RCTs conducted in adult TBI populations improved over the years; however, the quality of reporting remains below an acceptable level. The small sample sizes suggest that many RCTs are likely underpowered. Further improvement is recommended in designing and reporting RCTs.

Patient Characterization Protocols for Psychophysiological Studies of Traumatic Brain Injury and Post-TBI Psychiatric Disorders

Psychophysiological investigations of traumatic brain injury (TBI) are being conducted for several reasons, including the objective of learning more about the underlying physiological mechanisms of the pathological processes that can be initiated by a head injury. Additional goals include the development of objective physiologically based measures that can be used to monitor the response to treatment and to identify minimally symptomatic individuals who are at risk of delayed-onset neuropsychiatric disorders following injury. Research programs studying TBI search for relationships between psychophysiological measures, particularly ERP (event-related potential) component properties (e.g., timing, amplitude, scalp distribution), and a participant's clinical condition. Moreover, the complex relationships between brain injury and psychiatric disorders are receiving increased research attention, and ERP technologies are making contributions to this effort. This review has two objectives supporting such research efforts. The first is to review evidence indicating that TBI is a significant risk factor for post-injury neuropsychiatric disorders. The second objective is to introduce ERP researchers who are not familiar with neuropsychiatric assessment to the instruments that are available for characterizing TBI, post-concussion syndrome, and psychiatric disorders. Specific recommendations within this very large literature are made. We have proceeded on the assumption that, as is typically the case in an ERP laboratory, the investigators are not clinically qualified and that they will not have access to participant medical records.
