Virtual reality as a method of cognitive training of processing speed, working memory, and sustained attention in persons with acquired brain injury: a protocol for a randomized controlled trial.

Acquired brain injury (ABI) often leads to persisting somatic, cognitive, and social impairments. Cognitive impairments of processing speed, sustained attention, and working memory are frequently reported and may negatively affect activities of daily living and quality of life. Rehabilitation efforts aiming to retrain these cognitive functions have often consisted of computerized training programs. However, few studies have demonstrated effects that transfer beyond the trained tasks. There is a growing optimism regarding the potential usefulness of virtual reality (VR) in cognitive rehabilitation. The research literature is sparse, and existing studies are characterized by considerable methodological weaknesses. There is also a lack of knowledge about the acceptance and tolerability of VR as an intervention method for people with ABI. The present study aims to investigate whether playing a commercially available VR game is effective in training cognitive functions after ABI and to explore if the possible effects transfer into everyday functioning. One hundred participants (18-65years), with a verified ABI, impairments of processing speed/attention, and/or working memory, and a minimum of 12months post injury will be recruited. Participants with severe aphasia, apraxia, visual neglect, epilepsy, and severe mental illness will be excluded. Participants will be randomized into two parallel groups: (1) an intervention group playing a commercial VR game taxing processing speed, working memory, and sustained attention; (2) an active control group receiving psychoeducation regarding compensatory strategies, and general cognitive training tasks such as crossword puzzles or sudoku. The intervention period is 5weeks. The VR group will be asked to train at home for 30min 5days per week. Each participant will be assessed at baseline with neuropsychological tests and questionnaires, after the end of the intervention (5weeks), and 16weeks after baseline. After the end of the intervention period, focus group interviews will be conducted with 10 of the participants in the intervention group, in order to investigate acceptance and tolerability of VR as a training method. This study will contribute to improve understanding of how VR is tolerated and experienced by the ABI population. If proven effective, the study can contribute to new rehabilitation methods that persons with ABI can utilize in a home setting, after the post-acute rehabilitation has ended.

Family Functioning, Community Participation, and Rehabilitation Barriers in the Acquired Brain Injury Community: An Exploratory Analysis

Acquired brain injury (ABI) is the second most common cause of disability in America. Prior research highlights family functioning as an important predictor of psychosocial outcomes in the ABI population; however, there remains limited research aimed at understanding the role of family functioning in predicting rehabilitation progress and community participation. A quantitative, exploratory, descriptive research design was used for this study. A total sample of 49 individuals with mild-to-moderate ABI were recruited from a university medical center and outpatient rehabilitation center. Participants completed measures of demographics, community participation, family functioning, and perceived rehabilitation barriers. Data were analyzed using descriptive statistics and multiple regression (MR) analysis. Two MR models were examined, one with rehabilitation barriers as the dependent variable and one with community participation as the dependent variable. Financial support and perceived rehabilitation barriers contributed significantly to variance in community participation satisfaction, while financial support, family functioning, and community participation satisfaction each accounted for a significant portion of variance in perceived rehabilitation barriers. Overall, the full MR 1 model accounted for 33% of variance in community participation satisfaction, while the full MR 2 model accounted for 51% of variance in perceived rehabilitation barriers. Although more research with larger, more diverse samples is needed, this study provides rehabilitation and counseling professionals with important psychosocial concepts to consider in assessment and treatment and helps clarify the role of family in promoting positive rehabilitation and participation outcomes in the ABI community.

Family Therapy as an Intervention for Adults With Aphasia and Other Communication Disabilities After Acquired Brain Injury: A Scoping Review

Acquired brain injury (ABI) affects the whole family unit, significantly shifting family roles and relationships, with communication disabilities associated with ABI further compounding these difficulties. Family therapy is offered in situations where family roles have been disrupted, but research on the application of family therapy to families affected by ABI has not been synthesized. This study systematically maps the research on the use of family therapy in people with ABI, identifying to what extent people with communication disabilities (PWCD) are included in the evidence base. A scoping review of primary research was conducted through a systematic search of five multidisciplinary academic databases. A consultation process, involving a person with aphasia, ran alongside the entire research process. Twenty-four studies were included in the final review with four categories of interventions identified. Twelve studies excluded PWCD, 10 potentially doing so due to the communication demands of the study. Twelve studies included PWCD, five of which included speech and language therapists to support the delivery of family therapy. A small evidence base exists for the use of family therapy within an ABI population. However, PWCD are frequently excluded from this research due to the communication demands of the study designs. More research is needed to guide appropriate intervention for PWCD.

Distance horizontal fusional facility (DFF): A new diagnostic vergence test for the acquired brain injury (ABI) population

PurposeTo report the retrospectively-based, clinical diagnostic findings for the horizontal, distance, fusional facility (DFF) test in the non-TBI (traumatic brain inury), ABI (acquired brain injury) population. MethodsThe DFF test (4 pd base-out/2 pd base-in) was assessed and compared retrospectively in the first author's optometric practice in three clinical populations: (1) post-mTBI, visually-symptomatic (n = 52), (2) post-ABI, non-mTBI, visually-symptomatic (n = 34), and (3) visually-normal, visually asymptomatic (n = 44). ResultsThe DFF values in each group were significantly different from each other (p < 0.05). The mean non-TBI, ABI group value was significantly lower than found in the mTBI group, and both were significantly lower than the mean found in the normal cohort (p < 0.05). There was a significant reduction in DFF with increased age (p < 0.001). ROC values for the AUC ranged from excellent to acceptable (0.94–0.74). ConclusionThe DFF test is a new and useful way to assess horizontal, distance, dynamic, fusional facility in those with presumed non-mTBI, ABI neurological conditions to assist in its diagnosis.

Complete Vocal Technique-Voice Therapy as a Novel Intervention for Rehabilitation of Laryngeal-Phonatory Dysfunction in Acquired Brain Injury Patients—An Exploratory Retrospective Study

Purpose: The purpose of this study was to explore the use of Complete Vocal Technique (CVT) voice therapy in acquired brain injury (ABI) patients Study: This study is an exploratory retrospective study. Method: Five ABI patients (two female and three male) with an average age of 20.6 years ( SD = 3.5) received CVT voice therapy from an authorized CVT teacher at a neurorehabilitation facility in conjunction with physical rehabilitation therapy and speech and language therapy. Pre- and postmeasures included Voice Handicap Index, Maximum Phonation Time, electroglottography, and acoustic measures. Results: All voice measures improved for all five patients after receiving CVT voice therapy. Voice Handicap Index scores decreased from an average of 48.4 to 22.8. Maximum Phonation Time improved while the electroglottography and acoustic data showed improved phonation stability in jitter and shimmer measures. Overall, following the intervention, patients demonstrated improved loudness range, improved range in contact quotient for different sound conditions, faster-paced speech, extended functional pitch range, and decrease in unwanted creaking and breathiness. Conclusions: The findings suggest that CVT may be used as therapy in ABI populations with promising results. Both patient self-assessment and objective voice measures demonstrate improved voice function. Given the longitudinal nature of recovery in ABI patients, more studies are needed to qualify at which stage(s) of recovery the CVT interventions are most effective and beneficial. Randomized controlled trials for specific patient populations of ABI are needed to assess the interventions' effectiveness in specific ABI diagnoses.

Are sleep-related beliefs and behaviours dysfunctional in people with insomnia after acquired brain injury? A cross-sectional study.

Inappropriate sleep-related beliefs and behaviours are considered key maladaptive mechanisms in the development and maintenance of insomnia in the otherwise healthy population. The aim of this study was to evaluate critically the role of sleep-related beliefs and behaviours in insomnia after acquired brain injury. Cross-sectional data of 51 outpatients with insomnia disorder and acquired brain injury were used to evaluate associations of the insomnia severity index with the dysfunctional beliefs and attitudes about sleep scale and sleep-related behaviours questionnaire. Seven (44%) of the dysfunctional beliefs and attitudes about sleep scale items and 10 (31%) of the sleep-related behaviours questionnaire items correlated significantly with insomnia severity. Ten experts were consulted on whether they considered the questionnaire items maladaptive or accurately reflecting coping with conditions experienced by people with acquired brain injury. Although multiple linear regression showed that the total scores of the questionnaires explained a significant part of interindividual differences in insomnia severity (R2 = 0.27, F(2,48) = 8.72, p < 0.01), the experts unanimously rated only four (25%) of the dysfunctional beliefs and attitudes about sleep scale items as dysfunctional beliefs and three (9%) of the sleep-related behaviours questionnaire items as safety behaviours. In people with brain injury, sleep related beliefs and behaviours may also play a role in insomnia, especially a diminished perception of control and worry about sleep. However, more than half of the questionnaire items on sleep-related beliefs and behaviours may not be considered inappropriate and maladaptive for the acquired brain injury population, and may reflect adequate observations and efforts in coping with consequences of the brain damage.

Rehabilitation of Social Communication Skills in Patients With Acquired Brain Injury With Intensive and Standard Group Interactive Structured Treatment: A Randomized Controlled Trial

ObjectiveTo determine the efficacy of group interactive structured treatment (standard GIST) for improving social communication difficulties in a wider acquired brain injury (ABI) population compared to a waitlist control (WL). Secondary objectives were to (a) explore GIST across delivery formats by comparing the results to an intensive inpatient version of GIST (intensive GIST) and (b) compare the within-subject results for WL and intensive GIST. DesignRandomized controlled trial with WL and repeated measures (pre- and posttraining, 3- and 6-month follow-ups). SettingCommunity and rehabilitation hospital. ParticipantsForty-nine persons (27-74 years) with ABI and social communication difficulties (26.5% traumatic brain injury, 44.9% stroke, 28.6% other), minimum 12 months postinjury. InterventionStandard GIST (n=24) consisted of 12 weekly outpatient interactive group sessions (2.5 hours/session) and follow-up. Intensive GIST (n=18) consisted of 4 weeks with daily 4-hour inpatient group sessions (2 × 3 d/wk, 2 × 4 d/wk) and follow-up. Main Outcome MeasuresLa Trobe Questionnaire, a self-report questionnaire measuring social communication. Secondary measures: Social Communication Skills Questionnaire–Adapted, Goal Attainment Scale, Mind in the Eyes test, and questionnaires addressing mental and cognitive health, self-efficacy, and quality of life. ResultsWhen comparing the standard GIST and WL results, a trend of improvement was found for the main outcome, La Trobe Questionnaire, and a statistically significant improvement was found for the secondary outcome Social Communication Skills Questionnaire–Adapted. Comparing standard GIST and intensive GIST, improvement in social communication skills after both treatments was detected and maintained at 6-month follow-up. No statistically significant difference was found between groups. Goal attainment was achieved and maintained during follow-up for both standard and intensive GIST. ConclusionsSocial communication skills were improved after both standard and intensive GIST, indicating that GIST can be delivered across treatment formats and to a wider ABI population.

National quality standards for neuro rehabilitation in a community setting: Do they achieve their purpose?

There is known variation in neuro-rehabilitation service provision, however, the extent of service variation and impact on people who experience an acquired brain injury (ABI) is not articulated in the literature. The aim of this study was to assess and determine the extent to which neuro-rehabilitation services in one part of the United Kingdom (UK) are meeting national quality standards. A mixed method design, across five community neuro-rehabilitation providers and six districts in South London, comprised of ABI population incidence data, web-based surveys to determine compliance with the National Institute for Health and Care Excellence (NICE) Head Injury Quality Standard, and focus groups to understand the patient perspective of community neuro-rehabilitation service provision. The population incidence of ABI amongst districts demonstrated differences between the datasets analyzed, resulting in an inability to determine whether service variation was based on population need. The web-based surveys revealed that five community neuro-rehabilitation providers have variations between the models of care provided, including clinical referral criteria, duration, intensity of therapy interventions, and overall cost per patient, which was correlated with workforce capacity and patient waiting times. Focus group discussion highlighted current key challenges of service restraints, disconnect between services and limited professional support, as well as improvement opportunities pertaining to access, flexible, local and timely health and social care services. This study indicates that despite the publication of the NICE Head Injury Quality Standard, there is variation in the local provision of community neuro-rehabilitation across six districts in South London. Each district partly meets the recommendations, highlighting variability in the model of care delivered, that impacts consumers/carers accessing quality neuro-rehabilitation services. A disconnect remains between evidence-based quality standards and implementation. No standardized ABI data set is available in the UK, which impacts planning for future clinical service delivery.

Evaluating the effectiveness of compensatory memory interventions in adults with acquired brain injury: A systematic review and meta-analysis of memory and everyday outcomes.

Adults with acquired brain injury (ABI) often experience memory impairments that are persistent and difficult to treat. Although evidence has shown that rehabilitation programs may improve cognitive performance in persons with ABI, there is an opportunity to look more closely at the benefits provided by specific interventions. We conducted a systematic review and meta-analysis to evaluate whether compensation-based memory programs improve memory or everyday outcomes (e.g., mood, quality of life, community integration, everyday functioning). The review was limited to published, English-language controlled trials that evaluated compensatory memory interventions for adults (18 +) with ABI using at least one memory or everyday outcome. The final search was conducted in April 2021 using PsychINFO, Medline, EMBASE, the Cochrane Review database, Google Scholar, and the reference lists of relevant articles. Of 2,817 identified articles, 22 controlled trials met inclusion criteria, of which 12 provided sufficient data to include in the meta-analyses. Risk of bias assessment identified problems with recruitment and masking procedures. Results indicate that compared to controls, these interventions produce positive effects on outcomes of immediate verbal recall (g = 0.43), participant-reported memory (g = 0.28), and strategy use (g = 0.39) and that these improvements are maintained at follow-up. Compensatory memory programs produce meaningful memory improvements and are a promising avenue for reducing ABI-related memory impairment. Future research focusing on specific subsets of ABI populations and a broader range of participant-reported outcomes is needed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Change in care hours, cost, and functional independence following continence and assistive technology intervention in an acquired brain injury population

Purpose After acquired brain injury (ABI) dependence on intervention for continence management is common. This preliminary investigation aimed to (i) quantify toileting care hours and costs in a community-based ABI rehabilitation and disability setting, and (ii) measure change in care needs, costs, and functional independence after intervention with assistive technologies (ATs). Method Pragmatic pre-post intervention pilot study of 14 adults with ABI and toileting disability accessing community-based neurorehabilitation or disability support in Western Australia. Toileting and functional independence were assessed monthly from baseline (T 0) to 3-month follow-up (T 3). Basic and nursing care hours (Northwick Park Dependency Score), cost of care estimates (Northwick Park Care Needs Assessment), functional independence (Functional Independence and Assessment Measure), and cost of consumables were examined pre- and post-intervention with ATs. Multilevel mixed-effects models with bootstrap estimation were conducted. Results Cost of consumables significantly declined (AU$69/week), and functional independence significantly improved following intervention (+23.5 points). There was a non-significant reduction in care needs for toileting (4 h/week) and in the cost of toileting care (AU$633/week). Conclusion Toileting disability substantially impacts care hours and costs. This study provides preliminary evidence that comprehensive continence management is beneficial in reducing costs and supporting people with an ABI to increase their independence. IMPLICATIONS FOR REHABILITATION A comprehensive continence assessment and management plan reduces the number of care hours, cost of care, and cost of continence products in a neurorehabilitation and disability support sample for people with acquired brain injury (ABI). Assistive technologies for continence management are beneficial in supporting people with ABI to increase independence, and reduce costs. Providing comprehensive continence assessment and management plan reduces reliance on staff for continence care, and improves functional independence.

Does Intrathecal Baclofen Therapy Lead to an Improvement in Impairments and Functional Limitations in Patients With Acquired Brain Injury (ABI)? A Retrospective Study

Research Objectives To investigate effects of intrathecal baclofen (ITB) therapy on impairments and functional limitations in the acquired brain injury population(ABI). Design A retrospective study using chart reviews using a standardized data collection form on inpatient brain injury units to collect data on effects of ITB therapy on the ABI population with defined inclusion and exclusion criteria. A standardized data collection form was utilized along with a procedural manual for data abstraction. Setting Specialized acute and sub acute brain injury units. Participants Initially, 59 subjects were considered and a total of 15 medical records had sufficient data to analyze which met our criteria. 12 male patients (80%) and three female patients (20%). The mean age for ITB pump implantation was 35.5 years and the range was 18-67 years of age. Interventions Intrathecal Baclofen Pump Therapy with adjunctive therapies (for example skilled therapy, local Botox injections, serial casting, medication). Main Outcome Measures Modified Ashworth Scores, Passive Range of Motion, Mobility, JFK Coma Recovery Scale- Revised. Results The most significant change was noted with Modified Ashworth Scale (MAS) scores in the proximal hip muscle groups. Modified Ashworth Scale (MAS) scores with high significance (p-values ≤0.05) and large effect size (Cohen's D values >0.8) included right hip flexors, right hip extensors and R hip adductors. No statistically significant findings were found in other muscle groups, functional mobility, PROM and CRS-R (Coma Recovery Scale-Revised©) scales. Conclusions There were no significant changes noted in regards to functional status. However, data reflects improvements in spasticity of proximal hip musculature. This may result in improved positioning in bed or wheelchair as well as ease of hygiene and improved comfort. More research is recommended with a larger sample size and additional focus on pain and caregiver burden. Author(s) Disclosures All authors of this research study have no conflicts to disclose.

The psychological adjustment needs of individuals following an acquired brain injury: A systematic review

This systematic review explored the psychological adjustment needs of individuals following an acquired brain injury (ABI). Whilst the landscape of rehabilitation in ABI has changed rapidly over the last decade, there is still a lack of emphasis on psychological processes in this area. An electronic search of PsycArticles, PsycINFO, PubMed, JSTOR, and Cochrane Library databases was conducted for records between January 2009 and December 2019 detailing the psychological adjustment needs of individuals in a general ABI population. A total of 17 studies with varying methodologies were initially extracted. Methodological quality was then independently assessed by the three authors, with 14 articles meeting the quality threshold. Across methodologies, key themes emerged in relation to: difficulties adjusting to a new sense of self, the critical nature of social support, and the multifaceted nature of the adjustment process which incorporates many internal and external factors. These results illustrate the importance of psychological factors in ABI rehabilitation and as such highlight that the emphasis on functional outcomes in ABI may be an obstacle to the facilitation of the process of psychological adjustment. This provides justification for a more psychologically informed, holistic approach and inspires further debate as to the fundamental importance of psychological adjustment for individual’s post-ABI.

The Impact of Psycho-Social Interventions on the Wellbeing of Individuals With Acquired Brain Injury During the COVID-19 Pandemic.

Individuals with Acquired Brain Injury (ABI) suffer chronic impairment across cognitive, physical and psycho-social domains, and the experience of anxiety, isolation and apathy has been amplified by the COVID-19 pandemic. A qualitative evaluation was conducted of 14 individuals with ABI who had participated in series of COVID adapted group-based intervention(s) that had been designed to improve wellbeing. Eight themes were identified: Facilitating Safety, Fostering Positive Emotion, Managing and Accepting Difficult Emotions, Promoting Meaning, Finding Purpose and Accomplishment, Facilitating Social Ties, (Re)Connecting to Nature, and Barriers to Efficacy. Findings are discussed with respects to recent theoretical developments in positive psychology and wellbeing science and support the use of online and outdoor interventions to enhance wellbeing in individuals living with ABI during the COVID-19 pandemic. This paper makes a unique contribution to second wave positive psychology (PP2.0) through the application of recent advances in wellbeing science to an ABI population during the COVID-19 pandemic. In doing so, this paper lays the foundation for new interventions that not only reduce impairment and distress, but also create opportunities for meaning and enhanced wellbeing in people living with chronic conditions and those individuals living with ABI in particular.

Use of mHealth Technology for Patient-Reported Outcomes in Community-Dwelling Adults with Acquired Brain Injuries: A Scoping Review.

The purpose of our scoping review was to describe the current use of mHealth technology for long-term assessment of patient-reported outcomes in community-dwelling individuals with acquired brain injury (ABI). Following PRISMA guidelines, we conducted a scoping review of literature meeting these criteria: (1) civilians or military veterans, all ages; (2) self-reported or caregiver-reported outcomes assessed via mobile device in the community (not exclusively clinic/hospital); (3) published in English; (4) published in 2015–2019. We searched Ovid MEDLINE(R) < 1946 to 16 August 2019, MEDLINE InProcess, EPub, Embase, and PsycINFO databases for articles. Thirteen manuscripts representing 12 distinct studies were organized by type of ABI [traumatic brain injury (TBI) and stroke] to extract outcomes, mHealth technology used, design, and inclusion of ecological momentary assessment (EMA). Outcomes included post-concussive, depressive, and affective symptoms, fatigue, daily activities, stroke risk factors, and cognitive exertion. Overall, collecting patient-reported outcomes via mHealth was feasible and acceptable in the chronic ABI population. Studies consistently showed advantage for using EMA despite variability in EMA timing/schedules. To ensure best clinical measurement, research on post-ABI outcomes should consider EMA designs (versus single time-point assessments) that provide the best timing schedules for their respective aims and outcomes and that leverage mHealth for data collection.

Using a Marker-Less Motion Capture System to Assess Posture in Inpatient Rehabilitation With Acquired Brain Injury Populations With Visual Impairments

Establish feasibility of a marker-less motion capture system to assess posture and joint displacement in patents with acquired brain injury (ABI) and vision impairments in an inpatient neurorehabilitation setting.

Computer-based cognitive interventions in acquired brain injury: A systematic review and meta-analysis of randomized controlled trials.

Acquired brain injury (ABI) leads to cognitive deficits in a great variety of cognitive functions. Interventions aimed at reducing such deficits include the use of computer-based cognitive interventions. The present work synthetizes and quantitively analyses the effect of computer-based cognitive interventions in ABI. PubMed, Scopus, Web of Science, ProQuest and Ovid databases were searched for randomized controlled trials (RCT) addressing this issue. A total number of 8 randomized-controlled trials were included for systematic review and meta-analysis. Univariate meta-analyses were conducted for every cognitive function, producing aggregates when a study contributed more than one effect size per cognitive domain. Random-effects meta-analyses showed an improvement of Visual and Verbal working memory, while other domains like Attention, Processing speed, Executive functions and Memory were not benefited by the interventions. Computer-based cognitive interventions might be a beneficial intervention for ABI population to improve Visual and Verbal working memory, although no effect was found in other cognitive domains. Implications and possible future directions of the research are discussed.

Strategy-based reading comprehension therapy during early acquired brain injury rehabilitation: preliminary results

Introduction An evidence-based intervention and service delivery model for early acquired brain injury reading comprehension rehabilitation (involving multiple-strategy, hierarchical reading) was investigated with 3 clients <3 m post onset as part of their brain injury rehabilitation program. Materials and methods A multiple-baseline single case experimental design was used for each participant, with data analysed using Tau-U. Assessments of reading comprehension (impairment and activity level) were performed pre/post intervention, and at follow-up (3–6 months post-treatment). Participants’ perceptions of the intervention and service delivery model were captured via semi-structured interviews. Results All participants demonstrated improved reading comprehension post-intervention on all formal measures. At follow-up, reading comprehension was grossly maintained by 2 participants. The single case experimental design results (Tau-U) showed moderate-large intervention effect sizes for factual and inferential reading comprehension, two participants had significant (p = 0.01) changes. Participants reported overall positive experiences with the intervention. Conclusion The intervention and service delivery model were successfully implemented in clinical practice, and preliminary results show the intervention has clinical promise with an early acquired brain injury population. IMPLICATIONS FOR REHABILITATION Cognitive communication reading comprehension deficits occur following acquired brain injury and impact participation during rehabilitation and in the community. An evidence-based intervention for the early rehabilitation of cognitive communication reading comprehension deficits following acquired brain injury has been developed and trialled in clinical practice with adults <3 months post-acquired brain injury, via a series of single-case experimental designs. Improvements in reading comprehension skill and activity/participation occurred for all participants post-intervention; statistically significant changes occurred for 2 of 3 clients. Early rehabilitation of cognitive communication reading comprehension deficits can be successfully implemented as a component of a multidisciplinary rehabilitation program.

Minimum Clinically Important Difference of Gross Motor Function and Gait Endurance in Children with Motor Impairment: A Comparison of Distribution-Based Approaches.

Objective The minimum clinically important difference (MCID) is a standard way of measuring clinical relevance. The objective of this work was to establish the MCID for the 6-minute walking test (6minWT) and the Gross Motor Function Measure (GMFM-88) in pediatric gait disorders. Methods A cohort, pretest-posttest study was conducted in a hospitalized care setting. A total of 182 patients with acquired brain injury (ABI) or cerebral palsy (CP) performed 20 robot-assisted gait training sessions complemented with 20 sessions of physical therapy over 4 weeks. Separate MCIDs were calculated using 5 distribution-based approaches, complemented with an anonymized survey completed by clinical professionals. Results The MCID range for the 6minWT was 20-38 m in the ABI cohort, with subgroup ranges of 20-36 m for GMFCS I-II, 23-46 m for GMFCS III, and 24-46 m for GMFCS IV. MCIDs for the CP population were 6-23 m, with subgroup ranges of 4-28 m for GMFCS I-II, 9-19 m for GMFCS III, and 10-27 m for GMFCS IV. For GMFM-88 total score, MCID values were 1.1%-5.3% for the ABI cohort and 0.1%-3.0% for the CP population. For dimension “D” of the GMFM, MCID ranges were 2.3%-6.5% and 0.8%-5.2% for ABI and CP populations, respectively. For dimension “E,” MCID ranges were 2.8%-6.5% and 0.3%-4.9% for ABI and CP cohorts, respectively. The survey showed a large interquartile range, but the results well mimicked the distribution-based methods. Conclusions This study identified for the first time MCID ranges for 6minWT and GMFM-88 in pediatric patients with neurological impairments, offering useful insights for clinicians to evaluate the impact of treatments. Distribution-based methods should be used with caution: methods based on pre-post correlation may underestimate MCID when applied to patients with small improvements over the treatment period. Our results should be complemented with estimates obtained using consensus- and anchor-based approaches.

Detecting mental health problems after paediatric acquired brain injury: A pilot Rasch analysis of the strengths and difficulties questionnaire

ABSTRACT The parent-reported Strengths and Difficulties Questionnaire (SDQ-P) is commonly used to assess for mental health problems, but its psychometric properties have not been studied in the paediatric Acquired Brain Injury (ABI) population. This study investigated the properties of the SDQ-P and its subscales in this population using Rasch analysis. One hundred and forty-three SDQ-Ps and 123 Impact Supplements were analyzed. Sixty-nine percent of SDQ-Ps were completed by female carers, 59% of young people were male, and 58% had Traumatic Brain Injury (TBI). In this population the SDQ-P Total Difficulties Scale and the Conduct Problems subscale showed questionable construct validity. The individual subscales and Impact Supplement did not meet the criteria for reliability. Two items had disordered thresholds. The individual subscales showed mistargeting and 13–24% person misfit. Two items were significantly underdiscriminating. There was differential item functioning with age and time post-injury, and local dependence between subscale items. The Total Difficulties scale was multidimensional. The most easily endorsed items were in keeping with common symptoms of brain injury. These findings suggest the SDQ-P in its current form may not be a reliable and valid assessment measure for mental health difficulties in the paediatric ABI population and requires further investigation.

Sleep Measure Validation in a Pediatric Neurocritical Care Acquired Brain Injury Population.

Lingering morbidities including physical, cognitive, emotional, and psychosocial sequelae, termed the Post-Intensive Care Syndrome, persist years after pediatric neurocritical care (PNCC) hospitalization. Sleep disturbances impact other Post-Intensive Care Syndrome domains and are under-evaluated to date due to a lack of appropriate measurement tools. The present study evaluated the validity of the Sleep Disturbance Scale for Children (SDSC) to address the growing need for assessing sleep problems after PNCC. We conducted a prospective observational study of youth aged 3-17years with acquired brain injury (N = 69) receiving care through longitudinal PNCC programs at two tertiary academic medical centers. Parents completed the SDSC and provided proxy reports of internalizing symptoms, health-related quality of life (HRQOL), fatigue, pain behavior, and cognitive function within 3months of hospital discharge. Evidence for the validity of the SDSC was established by utilizing the full sample for psychosocial measure comparisons and by comparing SDSC outcomes by severity (Low Risk, Mild-Moderate Risk, and High Risk defined by reported standardized T-scores). Internal consistency of the SDSC was good (α = .81). Within the full sample, increased sleep disturbances on the SDSC were significantly correlated with Post-Intensive Care Syndrome measures, including worse physical (r = .65), psychological (r = .62), and cognitive (r = - .74) sequelae. Youth in the High Risk group evidenced greater dysfunction in mental acuity, pain behavior, internalizing symptoms, and social engagement. Findings revealed both statistically and clinically significant impacts of sleep disturbances as measured by the SDSC on HRQOL. The SDSC is a valid and reliable measure for assessing sleep disturbances in children after PNCC. Results support the use of the SDSC to measure sleep disturbances after PNCC. Targeted interventions for sleep disturbances may be key to overall patient recovery.
