Background Maladaptive illness perceptions are known to contribute to the development of persistent post-concussive symptoms 3-6months after mild traumatic brain injury (mTBI), but it is unclear which role these perceptions play in the chronic phase. This study examined which illness perceptions impact post-concussive and psychological symptoms in the chronic phase post-mTBI. Methods This observational study used data from 112 adults who experienced persistent symptoms following mTBI and were referred for multidisciplinary treatment. Measures included a short version of the Illness Perception Questionnaire, the Rivermead Post-Concussion Symptoms Questionnaire and the Brief Symptom Inventory 18. Results Specific illness perceptions were unique predictors of post-concussive symptoms (understanding, identity, duration and emotional response) as well as anxiety and depression symptoms (understanding and emotional response). Conclusion Although the aetiology of persistent post-concussive symptoms is multifactorial, the finding that specific illness perceptions contribute to experienced symptoms in the chronic phase post-mTBI underline the importance of psychoeducation and psychotherapeutic interventions in this population.

Introduction Locked-in syndrome (LIS) is a complex neurological condition characterised by paralysis of all four limbs and anarthria. Persons with LIS may communicate via eye blinks/low technology Augmentative and Alternative Communication devices (low tech AAC devices) or may use high technology Augmentative and Alternative Communication devices (high tech AAC devices). Our three objectives were: (1) to describe the distribution of communication modalities used by persons with LIS, (2) to describe the satisfaction of persons with LIS with their communication modality and social participation, and (3) to compare the characteristics and social participation among high tech AAC devices users versus low tech AAC devices or eye blinking users. Methods The questionnaires were sent by e-mail to persons with LIS. Data collected were communication modality, examination of communication ability, satisfaction with the communication modality and contribution of the communication modality to social participation. Results Of the 53 participants, their mean age was 52years, 43% used low tech AAC devices, 43% used high tech AAC devices and 13% communicated via eye blinking. Communication ability was examined in only half the participants. Participants' satisfaction with their communication modality in terms of ergonomics, rapidity, adaptability and functionality were 80, 67, 36 and 47% respectively. Participants who used high tech AAC devices had significantly better e-mail and social network access, could more often initiate conversations and had longer communication durations. Conclusion The communication abilities of persons with LIS should be examined as quickly as possible and repeated regularly. High tech AAC devices should be rapidly and systematically proposed.

Background There are currently 5.7million informal caregivers in the UK, with many experiencing psychological distress, compromised social functioning and poor quality of life. Improving the negative impact of caregiving has been a key focus of research in this population. However, there is limited research on the positive experiences of informal caregivers, particularly those caring for traumatic brain injury (TBI) survivors. This study aimed to explore whether informal TBI caregivers have positive experiences resulting from their role and investigate the possibility of post-traumatic growth (PTG). Methods Mixed-methods study. Quantitative data analysed using descriptive statistics. Qualitative data were analysed thematically. Data sets were synthesised and compared for agreement. Online semi-structured interviews were conducted with informal TBI caregivers, alongside a demographic questionnaire and validated PTG measure (Post-Traumatic Growth Inventory - Short Form, PTGI-SF). Results Ten TBI caregivers were recruited (n =10 male). The highest-scoring PTGI-SF domain across participants was 'personal strength' (mean=8.3; standard deviation, s.d.=1.5). The lowest-scoring domain was 'greater appreciation for life' (mean=7.1, s.d.=2.6). Six qualitative themes included: (1) deepened personal connections, (2) strengthened spiritual beliefs, (3) personal growth and resilience, (4) transformed life priorities and purpose, (5) improved coping mechanisms and (6) emergence of new opportunities and pathways. Findings revealed how caregivers adapted positively through caregiving experiences. Conclusions TBI caregivers appeared to experience PTG through caring. Future studies should employ mixed-methods to explore PTG in female TBI caregivers, adaptive coping strategies and the prevalence of occupational burden, facilitating the development of targeted interventions.

Background The Behavioural Assessment Screening Tool (BAST), which measures self-reported neurobehavioural symptoms experienced by adults with traumatic brain injury (TBI), was specifically developed as a self-reported measure for remote symptom reporting. Our aim was to assess the convergent, discriminant, and known-groups validity of the BAST among community-dwelling adults with TBI. Methods We assessed correlations and group differences with previously validated measures in two existing datasets (n =111, n =134). Other measures were the Patient Health Questionnaire-9 (depression), Generalized Anxiety Disorder-7 (anxiety), Positive and Negative Affect Schedule, Frontal Systems Behavior Scale (Executive Dysfunction, Apathy, Disinhibition), Modified Fatigue Impact Scale, Patient-Reported Outcomes Measurement Information System (Fatigue), Aggression Questionnaire (anger, hostility, physical and verbal aggression), and Alcohol Use Disorders Identification Test (alcohol misuse). Results BAST subscales had stronger correlations with measures of similar (|r |=0.602-0.828, P r |=0.364-0.589, P r |d =1.2-1.9) for known groups with moderate-severe depression, moderate-severe anxiety, fatigue, problematic disinhibited and frontal executive behaviours, and alcohol misuse. Results support the construct validity of the BAST subscales. Conclusion(s) The BAST demonstrated good convergent, discriminant, and known-groups validity, supporting its use for remote self-reported symptom reporting to improve chronic symptom monitoring in community-dwelling adults with TBI.

Background Cognitive-communication disorders are highly prevalent after traumatic brain injury and have significant impacts on rehabilitation outcomes. TBIBank Grand Rounds was developed as an online multimedia resource to support clinical education about cognitive-communication disorders. The objective of this study was to survey speech pathology educators to establish their views towards TBIBank Grand Rounds. Method An online survey with 37 items was distributed internationally to obtain a cross-section of international educators. The survey consisted of five sections covering (1) participant details; (2) awareness, interest, and use; (3) interface design and delivery; (4) content; and (5) overall impressions. The question formats included yes/no questions, multiple choice options, rating scales, and free text questions. Survey responses were analysed descriptively, with free text supporting interpretation. Results Twenty-five participants completed the online survey. Overall, most users agreed that the design and content of TBIBank Grand Rounds met their needs for supporting education about cognitive-communication disorders. The survey identified high interest but limited prior awareness of the resource. Survey respondents identified useful directions for updates, future enhancements, and dissemination of TBIBank Grand Rounds. Conclusions Incorporating feedback from educators has identified priorities for future enhancements, such as improving cultural diversity. High interest and positive feedback indicate that the TBIBank Grand Rounds is a valuable resource for education about cognitive-communication disorders. However, limited awareness internationally suggests the need for improved dissemination. Enhancing speech pathologists' knowledge about cognitive-communication disorders after TBI may lead to improved clinical care and outcomes.

Background Stroke now represents the condition with the highest need for physical rehabilitation worldwide, with only low or moderate-level evidence testing telerehabilitation compared to in-person care. We compared functional ambulation in subacute patients with stroke following telerehabilitation and matched in-person controls with no biopsychosocial differences at baseline. Methods We conducted a matched case-control study to compare functional ambulation between individuals with stroke following telerehabilitation and in-person rehabilitation, assessed using the Functional Ambulation Categories (FAC) and the Functional Independence Measure™ (FIM). Results The telerehabilitation group (n =38) achieved significantly higher FAC gains (1.5 (1.3) vs 1.0 (1.0)) than the in-person rehabilitation group, with no differences in ambulation efficiency, in individuals: admitted to rehabilitation within 60days after stroke onset; aged 49.8 (±11.4) years at admission; 55.3% female sex; moderate stroke severity; 42.1% with 'good' motor FIM at baseline; mostly living with sentimental partner (73.7%); with 21.1% holding an university education degree. Conclusions The groups showed no significant differences in ambulation efficiency, though the telerehabilitation group achieved higher FAC gains. Our results suggest that home telerehabilitation can be considered a good alternative to in-person rehabilitation when addressing ambulation in patients with moderate stroke severity and whose home situation mostly includes a cohabiting partner.

Background Many people with traumatic brain injury (TBI) report problems with social functioning that can have immediate and enduring impacts. We aimed to explore perceptions of social functioning after TBI and understand attitudes towards medication that could improve long-term social outcomes. Method A qualitative descriptive approach using interview methods was conducted in Victoria, Australia. Using purposive sampling we conducted 15 semi-structured interviews with people with moderate to severe TBI between July and September 2021. Results Using a framework approach, we thematically identified three themes: (1) impacts of TBI on social roles and activities, including changes in recreational activities and role changes in family units; (2) change in social networks, resulting from shifts in attitudes to social activities and mental health issues; and (3) openness to novel treatments to improve social functioning - willingness to take potential medication to improve social functioning and the factors that have an impact on decision making. Conclusion Our results highlight that people with TBI experience a range of changes in social participation post-TBI, and that they have a strong interest in improving their social functioning. Such insights provide opportunities to tailor patient-centric treatments and circumnavigate barriers in the early stages of medication development for successful translation into practice in this population.

Background This scoping review aimed to identify literature describing allied health interventions used to address challenging behaviour for adults with an acquired brain injury (ABI) living in community settings and identify the impact of these interventions on outcomes across the domains of behaviour, activity, and participation. Methods The Polyglot Search Translator for scoping reviews guided the search of six databases: (1) Ovid Medline®, (2) EmCARE (Ovid), (3) CINAHL Complete, (4) Embase (Ovid), (5) Scopus, and (6) Cochrane Library to identify literature published between 1990 and 2023. Results Of the 1748 records screened, 16 articles met the inclusion criteria. Studies commonly described therapeutic, least restrictive approaches to challenging behaviour founded on a positive behaviour support framework. Interventions were individualised, combining multiple elements to effect change in the environment, behaviour of the people providing support, and/or skills and behaviour of the person with ABI. Although most studies reported clinical gains from intervention, study designs used a range of methods and either single cases or mixed populations. Conclusions The findings of this review suggest that allied health interventions have the potential to reduce challenging behaviour experienced by people with ABI. However, further research addressing the impact of interventions on activity and participation is required to inform clinical practice and improve long-term outcomes.

Background Depression is commonly studied post stroke, while anxiety is less studied. This study presents prevalence of depression and anxiety at 1- and 12-months post ischemic stroke alongside three methods for examining within-subjects change over time. Methods Participants were ischemic stroke patients of the Auckland Regional Community Stroke Study (ARCOS-V) with Hospital Anxiety and Depression Scale data at 1- (n =343) and 12-months (n =307). Change over time was examined using within-subjects repeated measures ANOVA, calculation of the Reliable Change Index, and a Sankey diagram of those meeting cut-off scores (>7) for caseness over time. Results Using repeated measures ANOVA, depression scores didn't change significantly over time, while anxiety symptoms decreased significantly. When reliable change was calculated, 4.2% of individuals had reliable decreases in anxiety symptoms, while 5.7% had reliable decreases in depression symptoms. Those who had a reliable decrease in one tended to have a reliable decrease in the other. In the Sankey, the proportion of those meeting the cut-off score for anxiety did not change over time (12.8 and 12.7% at 1- and 12-months), while those meeting the cut-off for depression increased slightly (3.7-4.5%) and those meeting cut-offs for both decreased from 10.4 to 8.1%. Conclusion The three methods produced very different findings. Use of cut-off scores is common but has limitations. Calculation of clinically reliable change is recommended. Further work is needed to ensure depression and anxiety are monitored over time post-stroke, and both should be the subject of intervention efforts in both acute and late stages post-stroke.

Background and objectives Falls research has explored the characteristics of patients with a brain injury who experienced falls and the nature of these falls. However, the characteristics of falls with consequence have not yet been investigated. This study aimed to explore the consequences of patient falls in inpatient brain injury rehabilitation. Method Data were retrospectively analysed from incident reports and patient medical charts. Participants were included who had fallen during brain injury rehabilitation at a metropolitan hospital between January 2017 and December 2021. Falls with a reported consequence including pain, laceration, soft tissue injury, fracture and traumatic brain injury (consequential falls) were compared to falls that did not have a consequence. Significant patient and fall variables for a fall with consequence were explored. Results Over the 5-year study period 855 patients were admitted and 161 patients (64% male) experienced 276 falls. Of the 161 patients, 90 (56%) experienced a consequence from one or more falls, with 119 (43%) of falls having consequences. The odds of a consequential fall increased 1.03 times for each year increase in age. The odds of a consequential fall in autumn, winter, and spring were two to three times higher than in summer and were 3.6 times higher when the fall was unwitnessed by staff. Conclusions More falls with consequence occurred with increasing age and when unwitnessed by staff. This knowledge supports the need for older persons to have additional supervision and assistance during inpatient brain injury rehabilitation to reduce harm from falls.
