Physical activity and perceived barriers in individuals with moderate-to-severe traumatic brain injury

Feasibility and acceptability of an adapted peer-based walking intervention for adults with moderate-to-severe traumatic brain injury

PURPOSE

To examine the feasibility and acceptability of a 6-week peer-based walking intervention for adults with moderate-to-severe TBI with telehealth supports.

MATERIALS AND METHODS

Pre-post feasibility trial with 18 community-dwelling adults (10 men; 8 women) with moderate-to-severe TBI aged 21-61 years (M = 40.6, SD = 11.3). Feasibility outcomes included participation, attrition, safety across 12 90-minute sessions, and telehealth platform quality. Acceptability outcomes included program satisfaction. Exploratory outcomes included daily step count with activity trackers and pre-post intervention questionnaires (mood, leisure satisfaction, exercise self-efficacy, quality of life) through video conferencing.

RESULTS

15/18 (83%) participants completed ≥ 9 sessions (75%). Three participants were lost to attrition. No major adverse events reported. Minor events included fatigue and muscle soreness. Participants reported high satisfaction (M = 9.2/10, SD = 0.9). Average weekly steps per day rose from 10,011 to 11,177 steps (12%). Three participants' step count data were not included due to tremors or forgetting to wear the device (≥ 9 days). One major and several minor connectivity problems occurred. Wilcoxon Signed Ranks tests identified a significant change in negative affect (p < 0.002).

CONCLUSIONS

Findings support the feasibility and acceptability of a 6-week peer-based walking intervention with telehealth supports for our sample.

Body mass index and sleep disorders after moderate-to-severe traumatic brain injury - a national TBI model systems study

OBJECTIVE

To examine the relationship between body mass index (BMI), newly developed sleep disorders and functional outcome after moderate-to-severe traumatic brain injury (msTBI).

METHODS

Retrospective data from the TBI Model Systems National Database was analyzed, focusing on the independent association between BMI, sleep disorder diagnosis, and functional outcome as measured by the Extended Glasgow Outcome Scale (GOSE) at 1-year post-injury. Linear and logistic regression were used.

RESULTS

Out of 2,142 participants, 84% reported no sleep disorder (NSD), 9% reported a sleep disorder before TBI (PreSD), and 7% developed a sleep disorder after TBI (PostSD). Over 50% of participants were overweight or obese. After adjusting for demographic and clinical characteristics, a one-unit increase of BMI at the time of rehabilitation admission was associated with 3.7% higher odds of PostSD (OR [95%CI]: 1.037 [1.007, 1.068], p = 0.015). PostSD was associated with a 53.6% higher chance of unfavorable GOSE compared to NSD (OR [95%CI]: 1.536 [1.069-2.207], p = 0.02) and an 81.7% higher chance compared to PreSD (OR [95% CI]: 1.817 [1.137-2.905], p = 0.01).

CONCLUSION

Being overweight/obese and developing a sleep disorder had adverse effects on functional outcome, emphasizing the importance of addressing sleep and lifestyle factors in post-msTBI rehabilitation.

Impact of mild traumatic brain injury on health behaviors

Health-related behavioral changes may occur following traumatic brain injury. We focused on understanding the impact of mild traumatic brain injury (TBI) on health-related behaviors and identifying factors associated with such changes. We utilized health check-up records from the Korean National Health Insurance Service database spanning January 1, 2009, to December 31, 2017. The sample included 49,212 patients diagnosed with mild TBI and 1:1 matched controls who participated in national health check-ups in 2009-2010, 2011-2012, and 2016-2017. Multivariable logistic regression analysis was utilized to examine the association between mild TBI and short- and long-term health-related behavioral changes. Mild TBI was significantly associated with an increased risk of insufficient physical activity at the short- [odds ratio (OR), 1.04; 95% confidence interval (CI), 1.01 - 1.07] and long-term (OR, 1.06; 95% CI, 1.03 - 1.09) follow-ups. Age ≥ 65 years and female sex were significant effect modifiers for insufficient physical activity (OR, 1.11; 95% CI, 1.02 - 1.21) and smoking (OR, 1.31; 95% CI, 1.14 - 1.51), respectively. Mild TBI may lead to detrimental health-related behavioral changes, varying by age and sex. Thus, age- and sex-specific interventions may be needed to address these changes.

Predictors of Physical Activity One Year After Moderate to Severe Traumatic Brain Injury

OBJECTIVES

To identify predictors of moderate to vigorous physical activity (MVPA) at 12-months post-moderate-severe traumatic brain injury (TBI).

SETTING

Four inpatient rehabilitation centers.

PARTICIPANTS

Individuals enrolled in the TBI Model Systems with moderate to severe TBI, admitted to inpatient rehabilitation, and able to ambulate without physical assistance from another person.

DESIGN

Prospective longitudinal cohort study. MVPA was measured by having participants wear an ActiGraph GT3X on their wrist for 7 consecutive days.

MAIN ANALYSES

We used multivariate regression to predict minutes per week of MVPA at 12 months after TBI. Three classes of predictors were entered hierarchically-demographic and clinical variables (age, sex, body mass index, education, TBI severity, neighborhood walkability score, and self-reported preinjury physical activity [PA] level), baseline TBI-related comorbid conditions (eg, measures of sleep, pain, mood, fatigue, and cognition), and intention to exercise and exercise self-efficacy assessed approximately 1 week after discharge from inpatient rehabilitation.

RESULTS

180 participants (ages 17.7-90.3 years) were enrolled, and 102 provided at least 5 days of valid accelerometer data at 12 months. At 12 months, participants recorded an average of 703 (587) minutes per week of MVPA. In univariate and multivariate analyses, age was the only significant predictor of 12-month MVPA ( r = -0.52). A sharp decline in MVPA was observed in the tertile of participants who were over the age of 61.

CONCLUSIONS

Older adults with TBI are at elevated risk of being physically inactive. Assuming PA may enhance health after TBI, older adults are a logical target for prevention or early intervention studies. Studies with longer outcomes are needed to understand the trajectory of PA levels after TBI.

Barriers and enablers to physical activity for individuals living with traumatic brain injury: a mixed methods systematic review

BACKGROUND

Despite well-documented benefits of physical activity (PA), people with brain injury face numerous PA barriers. This mixed methods systematic review aimed to summarize barriers and enablers that individuals with traumatic brain injury (TBI) experience when participating in PA.

METHODS

Primary studies investigating barriers and/or enablers to PA in adults living with TBI were included. Literature search in MEDLINE, EmCare, Embase, PsychINFO, PEDro, and OTSeeker was initially conducted in December 2021 and January 2022, and updated in June 2022. Methodological quality of the included studies was assessed using Joanna Briggs Institute critical appraisal tools. A customized data extraction form was utilized. Descriptive synthesis was used to summarize the findings.

RESULTS

Twelve studies of various methodological qualities were identified. Barriers to PA included personal issues, changing health status, external factors, lack of support, and lack of knowledge. Identified enablers included personal drivers, social support, professional support, accessibility, and education.

CONCLUSIONS

The shared similarities between barriers and enablers across several themes suggest that multiple barriers may be amenable to change. Given the diverse barriers to PA, health professionals should use person-centered, holistic approach with ongoing review and monitoring, when engaging with individuals with TBI.

Aerobic exercise and cognitive function in chronic severe traumatic brain injury survivors: a within-subject A-B-A intervention study

BACKGROUND

Following acute and sub-acute rehabilitation from severe traumatic brain injury (TBI), minimal to no efficacious interventions to treat ongoing cognitive deficits are available. Aerobic exercise is a non-invasive behavioral intervention with promise to treat cognitive deficits in TBI populations.

METHODS

Six individuals, aged 24-62 years, with chronic (> 8 months since injury) severe (Glasgow Coma Scale of 3-8) TBI were recruited from two outpatient rehabilitation centers. In an A-B-A study design, 20-weeks of supervised aerobic exercise interventions were delivered three times per week (phase B) in addition to participants typical rehabilitation schedules (phases A). The effect of phase B was tested on a trail making test part B (primary outcome measure of executive function) as well as objective daily physical activity (PA), using both group level (linear mixed effect models) and single subject statistics.

RESULTS

Five of six participants increased trail-making test part B by more than 10% pre-to-post phase B, with three of six making a clinically meaningful improvement (+ 1SD in normative scores). A significant main effect of time was seen with significant improvement in trail-making test part B pre-to-post exercise (phase B). No significant effects in other planned comparisons were found. Statistically significant increases in daily moderate-to-vigorous PA were also seen during phase B compared to phase A with three of six individuals making a significant behaviour change.

CONCLUSIONS

The addition of supervised aerobic exercise to typical rehabilitation strategies in chronic survivors of severe TBI can improve executive set shifting abilities and increase voluntary daily PA levels.

TRIAL REGISTRATION

Retrospective trial registration on July 11 2024 with trial number: ISRCTN17487462.

Age-related smartphone use patterns among individuals with moderate-to-severe traumatic brain injury

OBJECTIVE

With mobile health technologies serving as an alternative means of providing healthcare, evaluating patients' abilities to navigate digital infrastructures is becoming increasingly relevant. The goal of this study is to investigate smartphone use patterns among individuals with history of moderate-to-severe traumatic brain injury (TBI).

METHODS

An anonymous survey was delivered via e-mail or text message to eligible participants who had a history of moderate-to-severe TBI and were prospectively followed at one of the eight participating Traumatic Brain Injury Model Systems centers for at least 1-year post-injury. The survey captured demographic data and included a questionnaire to evaluate smartphone use (calling, texting, web browsing, etc.).

RESULTS

A total of 2665 eligible individuals were contacted to complete the survey, 472 of which responded. 441 of them reported smartphone use. Individuals ages 45 and older were significantly less likely to use their phones for functions other than calling and texting when compared to individuals ages 18-44 (p < 0.05).

CONCLUSIONS

Most individuals with moderate-to-severe TBI in this cohort demonstrated intentional smartphone use, suggesting that mobile health technologies may be feasible as a cost-effective healthcare alternative. However, doing so will require additional interventions to provide further technological education especially in older individuals with TBI.

Physical Activity Preferences of People Living with Brain Injury: Formative Qualitative Research to Develop a Discrete Choice Experiment

BACKGROUND AND OBJECTIVE

The World Health Organization physical activity guidelines for people living with disability do not consider the needs of people living with moderate-to-severe traumatic brain injury. This paper describes the qualitative co-development of a discrete choice experiment survey to inform the adaption of these guidelines by identifying the physical activity preferences of people living with moderate-to-severe traumatic brain injury in Australia.

METHODS

The research team comprised researchers, people with lived experience of traumatic brain injury and health professionals with expertise in traumatic brain injury. We followed a four-stage process: (1) identification of key constructs and initial expression of attributes, (2) critique and refinement of attributes, (3) prioritisation of attributes and refinement of levels and (4) testing and refining language, format and comprehensibility. Data collection included deliberative dialogue, focus groups and think-aloud interviews with 22 purposively sampled people living with moderate-to-severe traumatic brain injury. Strategies were used to support inclusive participation. Analysis employed qualitative description and framework methods.

RESULTS

This formative process resulted in discarding, merging, renaming and reconceptualising attributes and levels. Attributes were reduced from an initial list of 17 to six: (1) Type of activity, (2) Out-of-pocket cost, (3) Travel time, (4) Who with, (5) Facilitated by and (6) Accessibility of setting. Confusing terminology and cumbersome features of the survey instrument were also revised. Challenges included purposive recruitment, reducing diverse stakeholder views to a few attributes, finding the right language and navigating the complexity of discrete choice experiment scenarios.

CONCLUSIONS

This formative co-development process significantly improved the relevance and comprehensibility of the discrete choice experiment survey tool. This process may be applicable in other discrete choice experiment studies.
