Estimating highest capacity propulsion performance using backward-directed force during walking evaluation for individuals with acquired brain injury.

There are over 5.3 million Americans who face acquired brain injury (ABI)-related disability as well as almost 800,000 who suffer from stroke each year. To improve mobility and quality of life, rehabilitation professionals often focus on walking recovery soon after hospital discharge for ABI. Reduced propulsion capacity (force output of the lower limbs to counteract ground reaction forces) negatively impacts walking ability and complicates recovery during rehabilitation for brain injured people. We describe a method, using backward-directed resistance (BDR) in a robotic-based treadmill device, to allow measurement of maximum walking propulsion force (MWPF) that is not otherwise possible during overground walking assessment. Our objective was to test the construct validity of a maximum walking propulsion force (MWPF) measure that reflects a person's propulsive strength against applied BDR, while walking on a robotic treadmill-based device for participants with acquired brain injury (ABI). Our study enrolled 14 participants with ABI at an in inpatient rehabilitation in Galveston, TX from 8/1/21 - 4/31/22. The range of weight-adjusted MWPF was 2.6-27.1% body weight (%BW), mean 16.5 ± 8.4%BW, reflecting a wide range of propulsive force capability. The strongest correlation with overground tests was between the 6-minute walk test (6-MWT) distance and the MWPF values (r = 0.83, p < 0.001) with moderate correlations between the 10-meter walk tests at comfortable (CWS) and fast speeds (FWS). The Five Times Sit-to-Stand (used as a standard clinical measure of functional lower extremity strength) and MWPF tests were poorly correlated (r = 0.26, p = 0.4). Forward model selection included 6-MWT distance, age, and overground CWS as significant partial predictors of MWPF. We conclude that this novel MWPF measure is a valid representation of maximum propulsive force effort during walking for people post-ABI. Additional research could help determine the impact of interventions designed to increase propulsive force generation during rehabilitation training to improve overground walking performance.

Transition from rehabilitation hospital to the National Disability Insurance Scheme (NDIS) for people with brain injury and spinal cord injury: a data linkage protocol.

INTRODUCTION: Traumatic brain injury (TBI) and spinal cord injury (SCI) are both major contributors to permanent disability globally, with an estimated 27 million new cases of TBI and 0.93 million new cases of SCI globally in 2016. In Australia, the National Disability Insurance Scheme (NDIS) provides support to people with disability. Reports from the NDIS suggest that the cost of support for people with TBI and SCI has been increasing dramatically, and there is a lack of independent analysis of the drivers of these increases. This data linkage seeks to better understand the participant transition between rehabilitation hospitals and the NDIS and the correlation between functional independence in rehabilitation and resource allocation in the NDIS. METHODS AND ANALYSIS: This is a retrospective, population-based cohort study using Australia-wide NDIS participant data and rehabilitation hospital episode data. The linked dataset provides a comparison of functional independence against which to compare the NDIS resource allocation to people with TBI and SCI. This protocol outlines the secure and separated data linkage approach employed in linking partially identified episode data from the Australasian Rehabilitation Outcomes Centre (AROC) with identified participant data from the NDIS. The linkage employs a stepwise deterministic linkage approach. Statistical analysis of the linked dataset will consider the relationship between the functional independence measure score from the rehabilitation hospital and the committed funding supports in the NDIS plan. This protocol sets the foundation for an ongoing data linkage between rehabilitation hospitals and the NDIS to assist transition to the NDIS. ETHICS AND DISSEMINATION: Ethics approval is from the Macquarie University Human Research Ethics Committee. AROC Data Governance Committee and NDIS Data Management Committee have approved this project. Research findings will be disseminated to key stakeholders through peer-reviewed publications in scientific journals and presentations to clinical and policy audiences via AROC and NDIS.

Process evaluation of a randomised controlled trial intervention designed to improve rehabilitation services for Aboriginal Australians after brain injury: the Healing Right Way Trial.

BACKGROUND: Healing Right Way (HRW) aimed to improve health outcomes for Aboriginal Australians with stroke or traumatic brain injury by facilitating system-level access to culturally secure rehabilitation services. Using a stepped-wedge randomised controlled trial (RCT) design (ACTRN12618000139279, 30/01/2018), a two-pronged intervention was introduced in four rural and four urban hospitals, comprising 1.Cultural security training (CST) for staff and 2.Training/employment of Aboriginal Brain Injury Coordinators (ABIC) to support Aboriginal patients for 6-months post-injury. Three-quarters of recruited patients lived rurally. The main outcome measure was quality-of-life, with secondary outcomes including functional measures, minimum processes of care (MPC); number rehabilitation occasions of service received, and improved hospital experience. Assessments were undertaken at baseline, 12- and 26-weeks post-injury. Only MPCs and hospital experience were found to improve among intervention patients. We report on the process evaluation aiming to support interpretation and translation of results. METHODS: Using mixed methods, the evaluation design was informed by the Consolidated Framework for Implementation Research. Data sources included minutes, project logs, surveys, semi-structured interviews, and observations. Four evaluation questions provided a basis for systematic determination of the quality of the trial. Findings from separate sources were combined to synthesise the emerging themes that addressed the evaluation questions. Three components were considered separately: the trial process, CST and ABIC. RESULTS: The complex HRW trial was implemented to a satisfactory level despite challenging setting factors, particularly rural-urban system dynamics. Patient recruitment constraints could not be overcome. The vulnerability of stepped-wedge designs to time effects influenced recruitment and trial results, due to COVID. Despite relatively high follow-up, including to rural/remote areas, data points were reduced. The lack of culturally appropriate assessment tools influenced the quality/completeness of assessment data. The ABIC role was deemed feasible and well-received. The CST involved complex logistics, but rated highly although online components were often incomplete. Project management was responsive to staff, patients and setting factors. CONCLUSIONS: Despite mostly equivocal results, the ABIC role was feasible within mainstream hospitals and the CST was highly valued. Learnings will help build robust state-wide models of culturally secure rehabilitation for Aboriginal people after brain injury, including MPC, workforce, training and follow-up.

CO-OP Approach With Children and Youth With Executive Function Deficits After Acquired Brain Injury: A Qualitative Study of Care Partners' Involvement.

IMPORTANCE: Care partners' involvement is a key feature of the Cognitive Orientation to daily Occupational Performance (CO-OP) approach that can enhance rehabilitation outcomes and promote the generalization and transfer of strategies and skills to everyday life. Gaining insight into care partners' experience with their child's CO-OP intervention is critical to understanding how to enhance care partners' involvement. OBJECTIVE: To gain insight into the experience of care partners whose child with acquired brain injury (ABI) participated in CO-OP intervention. METHOD: A qualitative descriptive research design was used. Semistructured interviews were conducted at three time points (immediate postintervention and at 2 and 6 mo postintervention). SETTING: Two rehabilitation centers. PARTICIPANTS: Thirteen care partners of 12 children or youth with severe ABI. RESULTS: Three themes emerged from the analysis of 33 interviews: (1) The child is an active agent in their therapy, (2) the care partner is the keystone who helps solidify the elements of CO-OP, and (3) CO-OP mastery requires time and practice, and its use evolves over time. CONCLUSIONS AND RELEVANCE: These themes highlight the progressive nature of proficiency in CO-OP for both care partners and children. This was evident not only in the children's improvement in task performance, but also in their ability to problem solve. Care partners' role in supporting the CO-OP approach also unfolds over time as their confidence in their child's problem-solving abilities, and in their own ability to adequately provide guidance, increases. Engagement seems to be central in facilitating this progression for both children and their care partners. Plain-Language Summary: This is the first study to provide insights into the involvement of care partners in the Cognitive Orientation to daily Occupational Performance (CO-OP) approach for children and youth with executive function deficits after acquired brain injury. This is also the first study to explore the evolution of care partners' experiences over time. Involving care partners is a key feature of the CO-OP. Understanding care partners' experiences with their child's CO-OP intervention can improve a child's rehabilitation outcomes. The study found that care partners' role in supporting their child's CO-OP approach improved over time as their confidence in their child's problem-solving abilities increased. The care partners' own ability to adequately provide guidance to their child also increased over time. Engagement seems to be central in facilitating this progression for both children and their care partners. It is hoped that occupational therapists will consider the findings of this study to better support care partners in implementing the CO-OP approach with their child in their real-life context.

Machine learning for automating subjective clinical assessment of gait impairment in people with acquired brain injury - a comparison of an image extraction and classification system to expert scoring.

BACKGROUND: Walking impairment is a common disability post acquired brain injury (ABI), with visually evident arm movement abnormality identified as negatively impacting a multitude of psychological factors. The International Classification of Functioning, Disability and Health (ICF) qualifiers scale has been used to subjectively assess arm movement abnormality, showing strong intra-rater and test-retest reliability, however, only moderate inter-rater reliability. This impacts clinical utility, limiting its use as a measurement tool. To both automate the analysis and overcome these errors, the primary aim of this study was to evaluate the ability of a novel two-level machine learning model to assess arm movement abnormality during walking in people with ABI. METHODS: Frontal plane gait videos were used to train four networks with 50%, 75%, 90%, and 100% of participants (ABI: n = 42, healthy controls: n = 34) to automatically identify anatomical landmarks using DeepLabCut™ and calculate two-dimensional kinematic joint angles. Assessment scores from three experienced neurorehabilitation clinicians were used with these joint angles to train random forest networks with nested cross-validation to predict assessor scores for all videos. Agreement between unseen participant (i.e. test group participants that were not used to train the model) predictions and each individual assessor's scores were compared using quadratic weighted kappa. One sample t-tests (to determine over/underprediction against clinician ratings) and one-way ANOVA (to determine differences between networks) were applied to the four networks. RESULTS: The machine learning predictions have similar agreement to experienced human assessors, with no statistically significant (p < 0.05) difference for any match contingency. There was no statistically significant difference between the predictions from the four networks (F = 0.119; p = 0.949). The four networks did however under-predict scores with small effect sizes (p range = 0.007 to 0.040; Cohen's d range = 0.156 to 0.217). CONCLUSIONS: This study demonstrated that machine learning can perform similarly to experienced clinicians when subjectively assessing arm movement abnormality in people with ABI. The relatively small sample size may have resulted in under-prediction of some scores, albeit with small effect sizes. Studies with larger sample sizes that objectively and automatically assess dynamic movement in both local and telerehabilitation assessments, for example using smartphones and edge-based machine learning, to reduce measurement error and healthcare access inequality are needed.

Intervention-Induced Changes in Balance and Task-Dependent Neural Activity in Adults with Acquired Brain Injury: A Pilot Randomized Control Trial.

Advances in neuroimaging technology, like functional near-infrared spectroscopy (fNIRS), support the evaluation of task-dependent brain activity during functional tasks, like balance, in healthy and clinical populations. To date, there have been no studies examining how interventions, like yoga, impact task-dependent brain activity in adults with chronic acquired brain injury (ABI). This pilot study compared eight weeks of group yoga (active) to group exercise (control) on balance and task-dependent neural activity outcomes. Twenty-three participants were randomized to yoga (n = 13) or exercise groups (n = 10). Neuroimaging and balance performance data were collected simultaneously using a force plate and mobile fNIRS device before and after interventions. Linear mixed-effects models were used to evaluate the effect of time, time x group interactions, and simple (i.e., within-group) effects. Regardless of group, all participants had significant balance improvements after the interventions. Additionally, regardless of group, there were significant changes in task-dependent neural activity, as well as distinct changes in neural activity within each group. In summary, using advances in sensor technology, we were able to demonstrate preliminary evidence of intervention-induced changes in balance and neural activity in adults with ABI. These preliminary results may provide an important foundation for future neurorehabilitation studies that leverage neuroimaging methods, like fNIRS.

Digital, co-created implementation of communication partner training programs for stroke, brain injury, and dementia: Past, present, and future.

PURPOSE: Communication partner training is a recommended intervention for partners of people with acquired brain injury. In this paper we explore the past, present, and future of communication partner training (CPT) based on our 2023 Speech Pathology Australia national conference address. METHOD: We focus on our research team's contributions, and highlight research knowledge across stroke, traumatic brain injury (TBI), and dementia. This work is anchored in the voice of people with communication disability. One partner in the CPT journey, Rosey Morrow, co-authors this paper. RESULT: The CPT evidence base for acquired neurological conditions is growing, including in the areas of technology, co-design, and translation. However, knowledge and implementation gaps remain. CONCLUSION: The future of CPT will require us to harness co-design and technology, whilst meeting the implementation challenges of complex systems to enable communication for all.

Survival and predictive factors of clinical outcome in patients with severe acquired brain injury.

BACKGROUND: Despite the many tools available to modern medicine, predicting the neurological and functional status of patients after severe brain injury remains difficult. AIM: This analysis evaluates the outcomes of patients with the most severe degree of cerebral function impairment. DESIGN: Retrospective cohort study. SETTING: Patients hospitalized in the long-term Intensive Care Unit (ICU) department in the Military University Hospital in Prague between 2015-2022. POPULATION: We analyzed patients with severe acquired brain damage from five distinct etiologies whose initial Glasgow Coma Scale (GCS) score was eight or less upon admission to ICU due to neurological damage. METHODS: Several parameters reflecting the patients' clinical status were evaluated. Overall survival after discharge from the ICU was calculated according to the Kaplan-Meier model with comparison between traumatic (TR) and non-traumatic (non-TR) etiologies. RESULTS: The analyzed cohort of 221 patients consisted of 116 patients of TR and 105 of non-TR etiology. There was no significant difference in overall survival between TR and non-TR groups. The length of hospitalization in the ICU was similar in both groups with a median of 94 days. The majority of patients had an improvement of GCS during the hospitalization with a median improvement of five points. GCS improvement occurred in the vast majority of patients regardless of TR or non-TR etiology. CONCLUSIONS: We did not observe a statistically significant difference in mortality or log-term neurological status between patients with severe brain injury of traumatic or non-traumatic etiology for the duration of our follow-up. The majority of patients had improved GCS, were successfully decannulated, but remained disabled with severe limitations of functional independence. CLINICAL REHABILITATION IMPACT: The return of the patient to normal life is a rehabilitation challenge, regardless of the etiology of brain injury, and is extremely influenced by the level of development of neurorehabilitation programs in individual institutions, the severity of brain injury, and the individual motivation of the patient.

Disorders of Consciousness.

This article reviews the definition, assessment, neuroimaging, treatment, and rehabilitation for disorders of consciousness after an acquired brain injury. It also explores special considerations and new neuromodulation treatment options.

Reclaiming Agency in Care Decisions and Barriers From the Perspectives of Individuals With Acquired Brain Injury and Their Family Members.

BACKGROUND: The ability to self-advocate or have a say in one's care is integral to personalised care after acquired brain injury (ABI). This study aimed to understand what constitutes self-advocacy and associated barriers and facilitators throughout hospital transitions and into the community. METHOD: Qualitative methodology was employed with semistructured interviews conducted with 12 people with ABI and 13 family members. Interviews were conducted at predischarge (in-person or via telephone) and 4 months postdischarge (via telephone) from the brain injury rehabilitation unit of a tertiary hospital. Data were thematically analysed using a hybrid deductive-inductive approach. RESULTS: Self-advocacy reflects the process of reclaiming agency or people's efforts to exert influence over care decisions after ABI. Agency varies along a continuum, often beginning with impaired processing of the self or environment (loss of agency) before individuals start to understand and question their care (emerging agency) and ultimately plan and direct their ongoing and future care (striving for agency). This process may vary across individuals and contexts. Barriers to self-advocacy for individuals with ABI include neurocognitive deficits that limit capacity and desire for control over decisions, unfamiliar and highly structured environments and lack of family support. Facilitators include neurocognitive recovery, growing desire to self-advocate and scaffolded support from family and clinicians. CONCLUSION: Self-advocacy after ABI entails a process of reclaiming agency whereby individuals seek to understand, question and direct their ongoing care. This is facilitated by neurocognitive recovery, growing capacity and desire and scaffolded supports. Research evaluating approaches for embedding self-advocacy skills early in brain injury rehabilitation is recommended. PATIENT OR PUBLIC CONTRIBUTION: Two caregivers with lived experience of supporting a family member with ABI were involved in the design and conduct of this study and contributed to and provided feedback on the manuscript.

Exploring the Role of Rehabilitation Medicine within an Inclusion Health Context: Examining a Population at Risk from Homelessness and Brain Injury in Edinburgh.

People experiencing homelessness are at risk from a number of comorbidities, including traumatic brain injury, mental health disorders, and various infections. Little is known about the rehabilitation needs of this population. This study took advantage of unique access to a specialist access GP practice for people experiencing homelessness and a local inclusion health initiative to explore the five-year period prevalence of these conditions in a population of people experiencing homelessness through electronic case record searches and to identify barriers and facilitators to healthcare provision for this population in the context of an interdisciplinary and multispecialist inclusion health team through semi-structured interviews with staff working in primary and secondary care who interact with this population. The five-year period prevalence of TBI, infections, and mental health disorders was 9.5%, 4%, and 22.8%, respectively. Of those who had suffered a brain injury, only three had accessed rehabilitation services. Themes from thematic analysis of interviews included the impact of psychological trauma, under-recognition of the needs of people experiencing homelessness, resource scarcity, and the need for collaborative and adaptive approaches. The combination of quantitative and qualitative data suggests a potential role for rehabilitation medicine in inclusion health initiatives.

Nutritional interventions and related efforts addressing undernutrition during rehabilitation after acquired brain injury: a scoping review protocol.

INTRODUCTION: Patients with an acquired brain injury (ABI) are at an increased risk of undernutrition due to the disease-related inflammation and other numerous symptoms that impact their nutrition. Unfortunately, recommendations related to nutritional interventions and related efforts vary. The objective of this scoping review is to map the body of literature on nutritional interventions and related efforts provided by health professionals, such as screening or assessments, addressing undernutrition in adults with a moderate to severe ABI during the subacute rehabilitation pathway. METHODS AND ANALYSIS: The review follows the Joanna Briggs Institute methodology for scoping reviews. The librarian-assisted search strategy will be conducted in the bibliographical databases: MEDLINE (PubMed), Embase, CINAHL, Web of Science and OpenGrey. Indexed and grey literature in English, German or Scandinavian languages from January 2010 will be considered for inclusion. Two independent reviewers will conduct the iterative process of screening the identified literature, paper selection and data extraction. Disagreements will be resolved by discussion until a consensus is reached. A template will be used to guide the data extraction. This scoping review will include research articles, methodological papers and clinical guidelines reporting on nutritional interventions or related efforts to prevent or address undernutrition in adult patients (≥18 years) with moderate to severe ABI within the first year after admission to rehabilitation hospital. We will map all kinds of nutritional efforts provided by professionals in different settings within high-income countries, including interventions targeting relatives. ETHICS AND DISSEMINATION: This review will involve the collection and analysis of secondary sources that have been published and/or are publicly available. Therefore, ethics approval is not required. The results will be published in an international peer-reviewed journal, presented at scientific conferences and disseminated through digital science communication platforms.

Short-term outcomes of early intensive neurorehabilitation for prolonged disorders of consciousness: A prospective cohort study.

BACKGROUND: Advances in medical care have increased survival in people with severe brain injuries and with that the number of survivors with prolonged disorders of consciousness (PDOC) has increased. In the literature, early intensive neurorehabilitation (EIN) for people with PDOC is recommended to achieve the best possible outcomes. OBJECTIVES: To evaluate the frequency and extent of recovery of consciousness, mortality, complications, pain and discomfort, and medication during a nationwide EIN programme in people with PDOC after acquired brain injury. We hypothesized that level of consciousness would improve in half of people with PDOC. METHODS: Prospective cohort study. People with PDOC aged 16 years and older admitted to the EIN department centralized in a single rehabilitation centre in the Netherlands (Libra Rehabilitation & Audiology) were included. The EIN delivers a subacute medical level of care and rehabilitation for a maximum duration of 14 weeks. The outcome measures were level of consciousness (CRS-R), mortality, number of complications, medication and pain/discomfort (NCS-R). RESULTS: Of the 104 people included, 68 % emerged to a minimal conscious state with command-following or higher during EIN and 44 % regained consciousness. Mortality during EIN was 6 %, and 50 % of deaths followed a non-treatment decision or withdrawal of life-sustaining treatment. Almost all participants had at least 1 medical complication, leading to hospital readmission for 30 %. 73 % showed no pain or discomfort. During EIN, cardiovascular medication and analgesics were reduced by 15 %. CONCLUSIONS: During the EIN programme, a large percentage of people with PDOC regained at least a minimal conscious state or even consciousness. These outcomes and the frequent medical complications in these people suggest that intensive specialized care should be offered to all people with PDOC. The outcomes of this study might help health professionals to better inform the families of people with PDOC about the short-term prognosis of PDOC.

Risk factors and service gaps affecting a sustainable work: a qualitative multi-stakeholder analysis in the context of persons with acquired brain injury living in Switzerland.

INTRODUCTION: Along with the social and economic challenges posed by an aging society, creating work conditions that allow persons to stay healthy and work into old age has become a major task of Western societies. Retaining employment after returning to work is particularly difficult for individuals with a disability, as evidenced by the high rate of premature labor market dropout. Individuals with acquired brain injury (ABI) exemplify this challenge, as it often impairs cognitive, technical, and interpersonal abilities that are crucial in today's labor market. To effectively support these individuals, vocational integration practitioners require comprehensive knowledge of risk factors for premature labor market dropout and effective strategies for sustainable work. OBJECTIVE: This study aimed to identify perceived risk factors and related service gaps regarding sustainable work for people with ABI, as reported by affected individuals, employers, vocational integration professionals, and health professionals. METHODS: Secondary data analysis. Data that was originally collected through seven focus groups and two interviews with persons with ABI, 15 interviews with employers, and 13 interviews with vocational integration and health professionals in the context of the project 'Sustainable employment' was re-analysed thematically. RESULTS: Two major themes of risk factors were identified: (1) person-related factors (including the subthemes: post-ABI impairments; lack of understanding of post-ABI impairments; poor health management) and (2) environment-related factors (including the subthemes: challenges related to the service structure; insufficient knowledge and education about ABI; challenges at the workplace; difficulties in private life). While stakeholders noted the variety of the currently available services, they particularly pointed to the missing long-term monitoring and counseling services for persons with ABI following the initial return-to-work, reflecting a major challenge for sustainable work. An overarching gap related to the fragmentation of the service structure and the lack of case coordination along the working life. CONCLUSIONS: Multiple stakeholders emphasized the importance of empowering individuals, ensuring easy access to professional support, and providing a suitable work environment to address key risk factors and facilitate sustainable work for individuals with ABI. Continuous coaching, long-term monitoring and counseling following return-to-work, were identified as potential strategies to achieve these goals.

Implications of the Consciousness State on Decannulation in Patients With a Prolonged Disorder of Consciousness.

OBJECTIVE: To prospectively investigate the evolution of the consciousness state and the cannula-weaning progression in patients with prolonged disorders of consciousness. DESIGN: Nonconcurrent cohort study. SETTING: A rehabilitation unit. PARTICIPANTS: Adult patients (N=144) with prolonged disorders of consciousness after a severe acquired brain injury admitted between June 2020 and September 2022. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Consciousness state was assessed by repeated Coma Recovery Scale-Revised (CRS-R) questionnaire administration at admission and weekly afterward. The dates of the first improvement of consciousness state and the achievement of decannulation were recorded. Decannulation followed an internal protocol of multiprofessional rehabilitation. RESULTS: One hundred forty-four patients were included: age, 69 years; 64 (44.4%) with hemorrhagic etiology; time post onset, 40 days, CRS-R score at admission, 9, median length of stay, 90 days. Seventy-three (50.7%) patients were decannulated. They showed a significantly higher CRS-R (P<.001) and states of consciousness (P<.001) at admission, at the first improvement of the consciousness state (P=.003), and at discharge (P<.001); a lower severity in the Cumulative Illness Rating Scale at admission (P=.01); and a lower rate of pulmonary infections with recurrence (P=.021), compared with nondecannulated patients. Almost all decannulated patients (97.3%) improved their consciousness before decannulation. Consciousness states at decannulation were as follows: unresponsive wakefulness syndrome, 0 (0%); minimally conscious state (MCS) minus, 4 (5.5%); MCS plus, 7 (9.6%); and emergence from MCS, 62 (84.9%). Kaplan-Meier analysis showed a significant divergence between the curves with a higher probability of decannulation in patients who improved consciousness (P<.001). CONCLUSIONS: This study showed that the presence of signs of consciousness, even subtle, is a necessary condition for decannulation, suggesting that consciousness may influence some of the components implied in the decannulation process.

[Early cognitive rehabilitation for patients with severe neurological impairment]. / Prise en charge cognitive précoce des patients cérébrolésés sévères.

Improving the state and future of patients severely impaired following brain injury is at the heart of early rehabilitation, established from the first days of hospitalization. For cognitive deficits, this management involves several challenges, related to hospital conditions and to the patients' capacities during the acute phase. A relevant intervention can be provided, as long as it involves an assessment adapted to these particularities and a rehabilitation targeting the most limiting deficits at this stage. These findings, discussed in the light of our clinical experience and current knowledge in the field, have yet to be scientifically tested since randomized clinical trials are still lacking. The integration of new technologies to facilitate the bedside work presents another prospect for the future.

Améliorer sans délai l'état et le devenir des patients sévèrement touchés par une lésion cérébrale constitue l'essence de la rééducation précoce, instaurée dès les premiers jours de l'hospitalisation. Pour les aspects cognitifs, cette prise en charge comporte plusieurs défis, liés aux conditions hospitalières et aux capacités des patients. Une intervention pertinente peut être pratiquée, sous réserve d'une évaluation adaptée à ces particularités et d'une rééducation ciblant les déficits les plus limitants à ce stade. Ces constats, discutés à la lumière de notre expérience clinique et des connaissances actuelles, doivent encore être prouvés scientifiquement car les essais cliniques randomisés manquent cruellement. L'intégration des nouvelles technologies pour faciliter le travail au chevet des patients constitue une autre perspective d'avenir.

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.

BACKGROUND: 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. METHODS: One hundred participants (18-65 years), with a verified ABI, impairments of processing speed/attention, and/or working memory, and a minimum of 12 months 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 5 weeks. The VR group will be asked to train at home for 30 min 5 days per week. Each participant will be assessed at baseline with neuropsychological tests and questionnaires, after the end of the intervention (5 weeks), and 16 weeks 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. DISCUSSION: 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.

Paroxysmal sympathetic hyperactivity during neurorehabilitation for severe acquired brain injury: current Scandinavian practice and Delphi consensus recommendations.

OBJECTIVES: To document current practice and develop consensus recommendations for the assessment and treatment of paroxysmal sympathetic hyperactivity (PSH) during rehabilitation after severe acquired brain injury. DESIGN: Delphi consensus process with three rounds, based on the Guidance on Conducting and REporting DElphi Studies (CREDES) guidelines, led by three convenors (the authors) with an expert panel. Round 1 was exploratory, with consensus defined before round 2 as agreement of at least 75% of the panel. SETTING: A working group within the Nordic Network for Neurorehabilitation. PANEL PARTICIPANTS: Twenty specialist physicians, from Sweden (9 participants), Norway (7) and Denmark (4), all working clinically with patients with severe acquired brain injury and with current involvement in clinical decisions regarding PSH. RESULTS: Consensus was reached for 21 statements on terminology, assessment and principles for pharmacological and non-pharmacological treatment, including some guidance on specific drugs. From these, an algorithm to support clinical decisions at all stages of inpatient rehabilitation was created. CONCLUSIONS: Considerable consensus exists in the Nordic countries regarding principles for PSH assessment and treatment. An interdisciplinary approach is needed. Improved documentation and collation of data on treatment given during routine clinical practice are needed as a basis for improving care until sufficiently robust research exists to guide treatment choices.

Feasibility of a physiotherapist-supervised walking program with telephone coaching to increase physical activity following acquired brain injury.

Background Physical activity has health benefits for adults with acquired brain injury, but it is a challenge to increase physical activity during inpatient rehabilitation. The objectives of this pilot study were to determine whether a physiotherapy-supervised inpatient walking program was feasible and able to improve physical activity and sedentary behaviour in the short and medium term. Methods Adults with acquired brain injury receiving inpatient rehabilitation undertook twice-weekly supervised walks plus behavioural therapy for 4 weeks. Feasibility was measured via recruitment, participation and drop out rates, adverse events and intervention delivery costs. Physical activity and sedentary behaviour were measured with an activPAL. Assessments were conducted at baseline, post-intervention and 3-6 months post-intervention. Results The program was safe to deliver (no adverse events), recruitment rate was 55% (16/29) and the participation rate for eligible individuals was high (14/19, 74%). However, the program had a high drop out rate (7/16, 44%) and physical activity and sedentary behaviour did not significantly change during the 4-week intervention. Costs were AU$427.71/participant. Physical activity and sedentary behaviour did improve 3-6 months after the intervention (vs baseline, on average: +3913 steps per day, 95% CI: 671, 7156). Conclusion This pilot study demonstrated a supervised physiotherapy walking program is safe and feasible to recruit in an inpatient setting. However, drop out during the study was high and behaviour change did not occur. More work is required to boost physical activity during sub-acute rehabilitation for acquired brain injury.

Investigating the Efficacy of a Community Support Network Rehabilitation Intervention for Improving Resiliency, Quality of Life, and Neurocognitive Function in Survivors of Intimate Partner Violence-Caused Brain Injury: Protocol for a Feasibility Study.

BACKGROUND: Globally, approximately 1 in 3 women experience intimate partner violence (IPV) in their lifetime. Brain injury (BI) is a common, yet often unrecognized, consequence of IPV. BIs caused by IPV tend to be mild, occur repetitively over the course of months or years, are remote in time, and result in chronic symptoms. Similar to BI from other causes, therapeutic treatment for women with IPV-caused BI (IPV-BI) is crucial to help resolve any physical or cognitive impairments, enhance the quality of life (QoL), and minimize longer-term neurodegeneration. OBJECTIVE: This study aims to investigate the feasibility and efficacy of a community support network (CSN) rehabilitation intervention regarding its impact on resiliency, QoL, and neurocognitive function. METHODS: In this pre- and postexperimental design, women (aged 18 to 50 years) who are survivors of IPV and IPV-BI will be recruited from various community organizations serving survivors of IPV. Exclusion criteria will include current pregnancy and any diagnosed neurological disorder known to affect cerebrovascular, neurocognitive, or sensorimotor function. A CSN rehabilitation intervention that includes aerobic exercise, cognitive training, mindfulness meditation, and counseling will be administered. A trauma-informed approach will be integrated into the design and implementation of the program. Furthermore, the program will include a participant navigator who will provide trauma- and violence-informed advocacy and systems navigation support to participants, in addition to facilitating a monthly peer support group. The intervention will be provided for 2.5 hours a day and 2 days a week for 3 months. Participants will complete psychological assessments and provide clinic-demographic information in the first assessment. In the second (before intervention), third (after intervention), and fourth (at follow-up) sessions, they will complete tests of resiliency, QoL, and neurocognition. The estimated sample size is 100. The objective of this study will be accomplished by quantitatively measuring resiliency, QoL, and neurocognition before and immediately after the intervention. A follow-up assessment will occur 3 months after the completion of the intervention to evaluate the maintenance of any improvements in function. One-way ANOVAs will be used to evaluate the intervention outcome across the testing times. Relationships among various variables will be explored using regression analysis. RESULTS: We anticipate that the CSN rehabilitation intervention will be effective in improving resiliency, QoL, and neurocognitive function in women who have experienced IPV-BI. Furthermore, we anticipate that this intervention will be feasible in terms of study recruitment, adherence, and retention. CONCLUSIONS: The CSN rehabilitation intervention will have a positive impact on resiliency, QoL, and neurocognitive functions in survivors of IPV-BI. Subsequently, a comparative study will be conducted by recruiting a control group receiving usual care. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): PRR1-10.2196/54605.
