Hospital-Based Health Professionals' Perceptions of Frailty in Older People.

BACKGROUND AND OBJECTIVES: There is a high prevalence of frailty amongst older patients in hospital settings. Frailty guidelines exist but implementation to date has been challenging. Understanding health professional attitudes, knowledge, and beliefs about frailty is critical in understanding barriers and enablers to guideline implementation and the aim of this study was to understand these in rehabilitation multidisciplinary teams in hospital settings. RESEARCH DESIGN AND METHODS: Twenty-three semi-structured interviews were conducted with health professionals working in multi-disciplinary teams on geriatric and rehabilitation wards in Adelaide and Sydney, Australia. Interviews were audio recorded, transcribed, and coded by two researchers. A codebook was created and interviews re-coded and applied to the Framework Method of thematic analysis. RESULTS: Three domains were developed: diagnosing frailty, communicating about frailty, and managing frailty. Within these domains, eight themes were identified: (1) diagnosing frailty has questionable benefits, (2) clinicians don't use frailty screening tools, (3) frailty can be diagnosed on appearance and history, (4) frailty has a stigma, (5) clinicians don't use the word "frail" with patients, (6) frailty isn't always reversible, (7) there is a lack of continuity of care after acute admission, and (8) the community setting lacks resources. DISCUSSION AND IMPLICATIONS: Implementation of frailty guidelines will remain challenging while staff avoid using the term "frail", don't perceive benefit of using screening tools, and focus on the individual aspects of frailty rather than the syndrome holistically. Clinical champions and education about frailty identification, reversibility, management, and communication techniques may improve the implementation of frailty guidelines in hospitals.

BEVA primary care clinical guidelines: Equine parasite control.

BACKGROUND: There is a lack of consensus on how best to balance our need to minimise the risk of parasite-associated disease in the individual horse, with the need to limit the use of anthelmintics in the population to preserve their efficacy through delaying further development of resistance. OBJECTIVES: To develop evidence-based guidelines utilising a modified GRADE framework. METHODS: A panel of veterinary scientists with relevant expertise and experience was convened. Relevant research questions were identified and developed with associated search terms being defined. Evidence in the veterinary literature was evaluated using the GRADE evidence-to-decision framework. Literature searches were performed utilising CAB abstracts and PubMed. Where there was insufficient evidence to answer the research question the panel developed practical guidance based on their collective knowledge and experience. RESULTS: Search results are presented, and recommendation or practical guidance were made in response to 37 clinically relevant questions relating to the use of anthelmintics in horses. MAIN LIMITATIONS: There was insufficient evidence to answer many of the questions with any degree of certainty and practical guidance frequently had to be based upon extrapolation of relevant information and the panel members' collective experience and opinions. CONCLUSIONS: Equine parasite control practices and current recommendations have a weak evidence base. These guidelines highlight changes in equine parasite control that should be considered to reduce the threat of parasite-associated disease and delay the development of further anthelmintic resistance.

The quality of care delivered to residents in long-term care in Australia: an indicator-based review of resident records (CareTrack Aged study).

BACKGROUND: This study estimated the prevalence of evidence-based care received by a population-based sample of Australian residents in long-term care (LTC) aged ≥ 65 years in 2021, measured by adherence to clinical practice guideline (CPG) recommendations. METHODS: Sixteen conditions/processes of care amendable to estimating evidence-based care at a population level were identified from prevalence data and CPGs. Candidate recommendations (n = 5609) were extracted from 139 CPGs which were converted to indicators. National experts in each condition rated the indicators via the RAND-UCLA Delphi process. For the 16 conditions, 236 evidence-based care indicators were ratified. A multi-stage sampling of LTC facilities and residents was undertaken. Trained aged-care nurses then undertook manual structured record reviews of care delivered between 1 March and 31 May 2021 (our record review period) to assess adherence with the indicators. RESULTS: Care received by 294 residents with 27,585 care encounters in 25 LTC facilities was evaluated. Residents received care for one to thirteen separate clinical conditions/processes of care (median = 10, mean = 9.7). Adherence to evidence-based care indicators was estimated at 53.2% (95% CI: 48.6, 57.7) ranging from a high of 81.3% (95% CI: 75.6, 86.3) for Bladder and Bowel to a low of 12.2% (95% CI: 1.6, 36.8) for Depression. Six conditions (skin integrity, end-of-life care, infection, sleep, medication, and depression) had less than 50% adherence with indicators. CONCLUSIONS: This is the first study of adherence to evidence-based care for people in LTC using multiple conditions and a standardised method. Vulnerable older people are not receiving evidence-based care for many physical problems, nor care to support their mental health nor for end-of-life care. The six conditions in which adherence with indicators was less than 50% could be the focus of improvement efforts.

The importance of self-regulation and mental health for effective recovery after traffic injuries: A comprehensive network analysis approach.

OBJECTIVE: Traffic injuries significantly impact people's psychological, physical and social wellbeing, and involve complex self-regulation responses. Psychological impacts are seldom recognized and addressed holistically. This study employs network analysis to investigate the interconnectedness between different dimensions that influence mental health vulnerability and recovery after traffic injuries. METHODS: 120 adults with mild-to-moderate traffic injuries and 112 non-injured controls were recruited. The network investigation employed two main approaches. Four cross-sectional networks examined the interrelationships between self-regulation responses (cognitive and autonomic) and various health dimensions (psychological, physical, social) over time (1, 3, 6, 12 months). Three predictive networks explored influences of acute self-regulation responses (1 month) on long-term outcomes. Network analyses focused on between-group differences in overall connectivity and centrality measures (nodal strength). RESULTS: An overall measure of psychological wellbeing consistently emerged as the most central (strongest) node in both groups' networks. Injured individuals showed higher overall connectivity and differences in the centrality of self-regulation nodes compared to controls, at 1-month and 12-months post-injury. These patterns were similarly observed in the predictive networks, including differences in cognitive and autonomic self-regulation influences. CONCLUSIONS: Network analyses highlighted the crucial role of psychological health and self-regulation, in promoting optimal wellbeing and effective recovery. Post-traffic injury, increased connectivity indicated prolonged vulnerability for at least a year, underscoring the need of ongoing support beyond the initial improvements. A comprehensive approach that prioritizes psychological health and self-regulation through psychologically informed services, early psychological screening, and interventions promoting cognitive and autonomic self-regulation is crucial for mitigating morbidity and facilitating recovery.

Heart Rate Variability Biofeedback in Adults with a Spinal Cord Injury: A Laboratory Framework and Case Series.

Heart rate variability biofeedback (HRV-F) is a neurocardiac self-regulation therapy that aims to regulate cardiac autonomic nervous system activity and improve cardiac balance. Despite benefits in various clinical populations, no study has reported the effects of HRV-F in adults with a spinal cord injury (SCI). This article provides an overview of a neuropsychophysiological laboratory framework and reports the impact of an HRV-F training program on two adults with chronic SCI (T1 AIS A and T3 AIS C) with different degrees of remaining cardiac autonomic function. The HRV-F intervention involved 10 weeks of face-to-face and telehealth sessions with daily HRV-F home practice. Physiological (HRV, blood pressure variability (BPV), baroreflex sensitivity (BRS)), and self-reported assessments (Fatigue Severity Scale, Generalised Anxiety Disorder Scale, Patient Health Questionnaire, Appraisal of Disability and Participation Scale, EuroQol Visual Analogue Scale) were conducted at baseline and 10 weeks. Participants also completed weekly diaries capturing mood, anxiety, pain, sleep quality, fatigue, and adverse events. Results showed some improvement in HRV, BPV, and BRS. Additionally, participants self-reported some improvements in mood, fatigue, pain, quality of life, and self-perception. A 10-week HRV-F intervention was feasible in two participants with chronic SCI, warranting further investigation into its autonomic and psychosocial effects.

The effect of doorway characteristics on freezing of gait in Parkinson's disease.

Background: Freezing of gait is a debilitating symptom in Parkinson's disease, during which a sudden motor block prevents someone from moving forward. Remarkably, doorways can provoke freezing. Most research has focused on the influence of doorway width, and little is known about other doorway characteristics influencing doorway freezing. Objective: Firstly, to provide guidelines on how to design doorways for people with freezing. Secondly, to compare people with doorway freezing to people without doorway freezing, and to explore the underlying mechanisms of doorway freezing. Methods: We designed a web-based, structured survey consisting of two parts. Part I (n = 171 responders), open to people with Parkinson's disease with freezing in general, aimed to compare people with doorway freezing to people without doorway freezing. We explored underlying processes related to doorway freezing with the Gait-Specific Attention Profile (G-SAP), inquiring about conscious movement processes occurring during doorway passing. Part II (n = 60), open for people experiencing weekly doorway freezing episodes, inquired about the influence of specific doorway characteristics on freezing. Results: People with doorway freezing (69% of Part I) had higher freezing severity, longer disease duration, and scored higher on all sub scores of the G-SAP (indicating heightened motor, attentional, and emotional thoughts when passing through doorways) than people without doorway freezing. The main categories provoking doorway freezing were: dimensions of the door and surroundings, clutter around the door, lighting conditions, and automatic doors. Conclusion: We provide recommendations on how to maximally avoid freezing in a practical setting. Furthermore, we suggest that doorways trigger freezing based on visuomotor, attentional, and emotional processes.

Exercise for falls prevention in aged care: systematic review and trial endpoint meta-analyses.

BACKGROUND: There is strong evidence that exercise reduces falls in older people living in the community, but its effectiveness in residential aged care is less clear. This systematic review examines the effectiveness of exercise for falls prevention in residential aged care, meta-analysing outcomes measured immediately after exercise or after post-intervention follow-up. METHODS: Systematic review and meta-analysis, including randomised controlled trials from a Cochrane review and additional trials, published to December 2022. Trials of exercise as a single intervention compared to usual care, reporting data suitable for meta-analysis of rate or risk of falls, were included. Meta-analyses were conducted according to Cochrane Collaboration methods and quality of evidence rated using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: 12 trials from the Cochrane review plus 7 new trials were included. At the end of the intervention period, exercise probably reduces the number of falls (13 trials, rate ratio [RaR] = 0.68, 95% confidence interval [CI] = 0.49-0.95), but after post-intervention follow-up exercise had little or no effect (8 trials, RaR = 1.01, 95% CI = 0.80-1.28). The effect on the risk of falling was similar (end of intervention risk ratio (RR) = 0.84, 95% CI = 0.72-0.98, 12 trials; post-intervention follow-up RR = 1.05, 95% CI = 0.92-1.20, 8 trials). There were no significant subgroup differences according to cognitive impairment. CONCLUSIONS: Exercise is recommended as a fall prevention strategy for older people living in aged care who are willing and able to participate (moderate certainty evidence), but exercise has little or no lasting effect on falls after the end of a programme (high certainty evidence).

Complex lived experiences and hidden disability after spinal cord injury: a latent profile analysis of the Australian arm of the International Spinal Cord Injury (Aus-InSCI) Community Survey.

PURPOSE: To identify and examine subgroups of people with spinal cord injury (SCI) with different patterns of lived experience, and examine hidden impairments and disability among functionally independent and ambulant people. MATERIALS AND METHODS: Latent profile analysis of population-based data from the Australian arm of the International Spinal Cord Injury (InSCI) Community survey (n = 1579). RESULTS: Latent subgroups reflected levels of functional independence and extent of problems with health, activity/participation, environmental barriers, and self-efficacy. Quality of life (QoL), psychological profiles, and activity/participation were often as good or better in participants who reported lower (vs. higher) functional independence alongside comparable burden of health problems and environmental barriers. QoL, mental health, and vitality reflected self-efficacy and problem burdens more closely than functional independence. Ambulant participants reported a substantial burden of underlying, potentially hidden impairments, with QoL and mental health similar to wheelchair users. CONCLUSION: Hidden disability among more independent and/or ambulant people with SCI can affect well-being substantially. Early and ongoing access to support, rehabilitation, and SCI specialist services is important irrespective of cause, type, severity of injury, and level of functional independence. Improved access to SCI expertise and equity of care would help to improve early recognition and management of hidden disability. TRIAL REGISTRATION: Not applicable.

Hidden disability can substantially affect the well-being and quality of life of people with spinal cord injury (SCI) who appear to be functioning well and independently.Early and ongoing access to rehabilitation and SCI specialist services is important for people with SCI of any cause, type, severity, and level of functional independence.The potential for and implications of hidden disability are key considerations for the broader community of health practitioners who manage people with SCI, to ensure that appropriate referrals to specialist SCI services occur.Hidden disability is a key consideration in the design and implementation of disability support systems.

Critical features of multifactorial interventions for effective falls reduction in residential aged care: a systematic review, intervention component analysis and qualitative comparative analysis.

BACKGROUND: Multifactorial fall prevention trials providing interventions based on individual risk factors have variable success in aged care facilities. To determine configurations of trial features that reduce falls, intervention component analysis (ICA) and qualitative comparative analysis (QCA) were undertaken. METHODS: Randomised controlled trials (RCTs) from a Cochrane Collaboration review (Cameron, 2018) with meta-analysis data, plus trials identified in a systematic search update to December 2021 were included. Meta-analyses were updated. A theory developed through ICA of English publications of trialist's perspectives was assessed through QCA and a subgroup meta-analysis. RESULTS: Pooled effectiveness of multifactorial interventions indicated a falls rate ratio of 0.85 (95% confidence interval, CI, 0.65-1.10; I2 = 85%; 11 trials). All tested interventions targeted both environmental and personal risk factors by including assessment of environmental hazards, a medical or medication review and exercise intervention. ICA emphasised the importance of co-design involving facility staff and managers and tailored intervention delivery to resident's intrinsic factors for successful outcomes. QCA of facility engagement plus tailored delivery was consistent with greater reduction in falls, supported by high consistency (0.91) and coverage (0.85). An associated subgroup meta-analysis demonstrated strong falls reduction without heterogeneity (rate ratio 0.61, 95%CI 0.54-0.69, I2 = 0%; 7 trials). CONCLUSION: Multifactorial falls prevention interventions should engage aged care staff and managers to implement strategies which include tailored intervention delivery according to each resident's intrinsic factors. Such approaches are consistently associated with a successful reduction in falls, as demonstrated by QCA and subgroup meta-analyses. Co-design approaches may also enhance intervention success.

A vocational intervention that enhances return to work after severe acquired brain injury: A pragmatic trial.

BACKGROUND: Following a severe acquired brain injury, individuals often have low return to work rates. The Vocational Intervention Program (VIP), a partnership of Brain Injury Rehabilitation Program community rehabilitation centres with external vocational rehabilitation providers in New South Wales, Australia, was developed to facilitate a return to competitive employment for working-age people. OBJECTIVES: To evaluate the efficacy of the VIP partnership model, this intervention was compared to outcomes from a health-based brain injury vocational rehabilitation centre (H-VR) or community brain injury rehabilitation centres ("treatment as usual"; TAU). METHODS: A 3-arm non-randomized controlled trial was conducted among the 12 adult rehabilitation centres of the NSW Brain Injury Rehabilitation Program. The VIP arm was delivered by 6 community rehabilitation centres in partnership with 3 external private Vocational Rehabilitation providers. The H-VR arm was delivered by 1 health-based vocational rehabilitation centre and the 5 remaining centres delivered TAU. Competitive employment status ("Yes"/"No") and clinician ratings of disability and participation were collected pre- and post-intervention, and at 3-month follow-up. Multilevel models were conducted to investigate change over time by treatment arm. RESULTS: In total, 148 individuals with severe brain injury were included in the trial: n = 75 (VIP), n = 33 (H-VR) and n = 40 (TAU). Sixty-five people (of 108, 60%) completed the VR intervention. A significant arm-by-time interaction was found, with higher return to work rates from pre- to post-intervention in VIP and H-VR arms compared to TAU (P = 0.0002). Significant arm-by-time interactions also indicated improved work-related participation and independent living skills from pre- to post-intervention in VIP and H-VR compared to the TAU arm (P < 0.05). These improvements were maintained at 3-month follow-up. CONCLUSIONS: The VIP improved return to competitive employment at comparable rates to the specialist H-VR. Larger-scale adoption of the VIP model could provide significant improvements in vocational rehabilition sevices to support people in their return to work following severe brain injury.

Unsafe care in residential settings for older adults: a content analysis of accreditation reports.

Residents of aged care services can experience safety incidents resulting in preventable serious harm. Accreditation is a commonly used strategy to improve the quality of care; however, narrative information within accreditation reports is not generally analysed as a source of safety information to inform learning. In Australia, the Aged Care Quality and Safety Commission (ACQSC), the sector regulator, undertakes over 500 accreditation assessments of residential aged care services against eight national standards every year. From these assessments, the Aged Care Quality and Safety Commission generates detailed Site Audit Reports. In over one-third (37%) of Site Audit Reports, standards relating to Personal and Clinical Care (Standard 3) are not being met. The aim of this study was to identify the types of resident Safety Risks that relate to Personal and Clinical Care Standards not being met during accreditation or re-accreditation. These data could inform priority setting at policy, regulatory, and service levels. An analytical framework was developed based on the World Health Organization's International Classification for Patient Safety and other fields including Clinical Issue (the issue related to the incident impacting the resident, e.g. wound/skin or pain). Information relating to safety incidents in the Site Audit Reports was extracted, and a content analysis undertaken using the analytical framework. Clinical Issue and the International Classification for Patient Safety-based classification were combined to describe a clinically intuitive category ('Safety Risks') to describe ways in which residents could experience unsafe care, e.g. diagnosis/assessment of pain. The resulting data were descriptively analysed. The analysis included 65 Site Audit Reports that were undertaken between September 2020 and March 2021. There were 2267 incidents identified and classified into 274 types of resident Safety Risks. The 12 most frequently occurring Safety Risks account for only 32.3% of all incidents. Relatively frequently occurring Safety Risks were organisation management of infection control; diagnosis/assessment of pain, restraint, resident behaviours, and falls; and multiple stages of wounds/skin management, e.g. diagnosis/assessment, documentation, treatment, and deterioration. The analysis has shown that accreditation reports contain valuable data that may inform prioritization of resident Safety Risks in the Australian residential aged care sector. A large number of low-frequency resident Safety Risks were detected in the accreditation reports. To address these, organizations may use implementation science approaches to facilitate evidence-based strategies to improve the quality of care delivered to residents. Improving the aged care workforces' clinical skills base may address some of the Safety Risks associated with diagnosis/assessment and wound management.

Early and intensive motor training to enhance neurological recovery in people with spinal cord injury: trial protocol.

STUDY DESIGN: Protocol for a multi-centre randomised controlled trial (the SCI-MT trial). OBJECTIVES: To determine whether 10 weeks of intensive motor training enhances neurological recovery in people with recent spinal cord injury (SCI). SETTING: Fifteen spinal injury units in Australia, Scotland, England, Italy, Netherlands, Norway, and Belgium. METHODS: A pragmatic randomised controlled trial will be undertaken. Two hundred and twenty people with recent SCI (onset in the preceding 10 weeks, American Spinal Injuries Association Impairment Scale (AIS) A lesion with motor function more than three levels below the motor level on one or both sides, or an AIS C or D lesion) will be randomised to receive either usual care plus intensive motor training (12 h of motor training per week for 10 weeks) or usual care alone. The primary outcome is neurological recovery at 10 weeks, measured with the Total Motor Score from the International Standards for Neurological Classification of SCI. Secondary outcomes include global measures of motor function, ability to walk, quality of life, participants' perceptions about ability to perform self-selected goals, length of hospital stay and participants' impressions of therapeutic benefit at 10 weeks and 6 months. A cost-effectiveness study and process evaluation will be run alongside the trial. The first participant was randomised in June 2021 and the trial is due for completion in 2025. CONCLUSIONS: The findings of the SCI-MT Trial will guide recommendations about the type and dose of inpatient therapy that optimises neurological recovery in people with SCI. TRIAL REGISTRATION: ACTRN12621000091808 (1.2.2021).

eHealth in Geriatric Rehabilitation: An International Survey of the Experiences and Needs of Healthcare Professionals.

While eHealth can help improve outcomes for older patients receiving geriatric rehabilitation, the implementation and integration of eHealth is often complex and time-consuming. To use eHealth effectively in geriatric rehabilitation, it is essential to understand the experiences and needs of healthcare professionals. In this international multicentre cross-sectional study, we used a web-based survey to explore the use, benefits, feasibility and usability of eHealth in geriatric rehabilitation settings, together with the needs of working healthcare professionals. Descriptive statistics were used to summarize quantitative findings. The survey was completed by 513 healthcare professionals from 16 countries. Over half had experience with eHealth, although very few (52 of 263 = 20%) integrated eHealth into daily practice. Important barriers to the use or implementation of eHealth included insufficient resources, lack of an organization-wide implementation strategy and lack of knowledge. Professionals felt that eHealth is more complex for patients than for themselves, and also expressed a need for reliable information concerning available eHealth interventions and their applications. While eHealth has clear benefits, important barriers hinder successful implementation and integration into healthcare. Tailored implementation strategies and reliable information on effective eHealth applications are needed to overcome these barriers.

Implementation of a frailty intervention in the transition from hospital to home: a realist process evaluation protocol for the FORTRESS trial.

INTRODUCTION: Frailty in Older people: Rehabilitation, Treatment, Research Examining Separate Settings (the FORTRESS study) is a multisite, hybrid type II, stepped wedge, cluster, randomised trial examining the uptake and outcomes of a frailty intervention. The intervention is based on the 2017 Asia Pacific Clinical Practice Guidelines for the Management of Frailty and begins in the acute hospital setting and transitions to the community. The success of the intervention will require individual and organisational behaviour change within a dynamic health system. This process evaluation will examine the multiple variables at play in the context and mechanism of the frailty intervention to enhance understanding of the outcomes of the FORTRESS study and how the outcomes can be translated from the trial into broader practice. METHODS AND ANALYSIS: The FORTRESS intervention will recruit participants from six wards in New South Wales and South Australia, Australia. Participants of the process evaluation will include trial investigators, ward-based clinicians, FORTRESS implementation clinicians, general practitioners and FORTRESS participants. The process evaluation has been designed using realist methodology and will occur in parallel to the FORTRESS trial. A mixed-method approach will be used with qualitative and quantitative data collected from interviews, questionnaires, checklists and outcome assessments. Qualitative and quantitative data will be examined for CMOCs (Context, Mechanism, Outcome Configurations) and programme theories will be developed, tested and refined. This will facilitate development of more generalisable theories to inform translation of frailty intervention within complex healthcare systems. ETHICS AND DISSEMINATION: Ethical approval for the FORTRESS trial, inclusive of the process evaluation, has been obtained from the Northern Sydney Local Health District Human Research Ethics Committees reference number 2020/ETH01057. Recruitment for the FORTRESS trial uses opt-out consent. Dissemination will be via publications, conferences and social media. TRIAL REGISTRATION NUMBER: ACTRN12620000760976p (FORTRESS trial).

Implementation of a risk-stratified, guideline-based clinical pathway of care to improve health outcomes following whiplash injury (Whiplash ImPaCT): a multicentre, randomized, controlled trial.

ABSTRACT: Current pathways of care for whiplash follow a "stepped care model," result in modest treatment outcomes and fail to offer efficient management solutions. This study aimed to evaluate the effectiveness of a risk-stratified clinical pathway of care (CPC) compared with usual care (UC) in people with acute whiplash. We conducted a multicentre, 2-arm, parallel, randomised, controlled trial in primary care in Australia. Participants with acute whiplash (n = 216) were stratified for risk of a poor outcome (low vs medium/high risk) and randomised using concealed allocation to either the CPC or UC. In the CPC group, low-risk participants received guideline-based advice and exercise supported by an online resource, and medium-risk/high-risk participants were referred to a whiplash specialist who assessed modifiable risk factors and then determined further care. The UC group received care from their primary healthcare provider who had no knowledge of risk status. Primary outcomes were neck disability index (NDI) and Global Rating of Change (GRC) at 3 months. Analysis blinded to group used intention-to-treat and linear mixed models. There was no difference between the groups for the NDI (mean difference [MD] [95% confidence interval (CI)] -2.34 [-7.44 to 2.76]) or GRC (MD 95% CI 0.08 [-0.55 to 0.70]) at 3 months. Baseline risk category did not modify the effect of treatment. No adverse events were reported. Risk-stratified care for acute whiplash did not improve patient outcomes, and implementation of this CPC in its current form is not recommended.

Frequency, duration, and type of physiotherapy in the week after hip fracture surgery - analysis of implications for discharge home, readmission, survival, and recovery of mobility.

PURPOSE: To examine the association between physiotherapy access after hip fracture and discharge home, readmission, survival, and mobility recovery. METHODS: A 2017 Physiotherapy Hip Fracture Sprint Audit was linked to hospital records for 5383 patients. Logistic regression was used to estimate the association between physiotherapy access in the first postoperative week and discharge home, 30-day readmission post-discharge, 30-day survival and 120-days mobility recovery post-admission adjusted for age, sex, American Society of Anesthesiology grade, Hospital Frailty Risk Score and prefracture mobility/residence. RESULTS: Overall, 73% were female and 40% had high frailty risk. Patients who received ≥2 hours of physiotherapy (versus less) had 3% (95% Confidence Interval: 0-6%), 4% (2-6%), and 6% (1-11%) higher adjusted probabilities of discharge home, survival, and outdoor mobility recovery, and 3% (0-6%) lower adjusted probability of readmission. Recipients of exercise (versus mobilisation alone) had 6% (1-12%), 3% (0-7%), and 11% (3-18%) higher adjusted probabilities of discharge home, survival, and outdoor mobility recovery, and 6% (2-10%) lower adjusted probability of readmission. Recipients of 6-7 days physiotherapy (versus 0-2 days) had 8% (5-11%) higher adjusted probability of survival. For patients with dementia, improved probability of survival, discharge home, readmission and indoor mobility recovery were observed with greater physiotherapy access. CONCLUSION: Greater access to physiotherapy was associated with a higher probability of positive outcomes. For every 100 patients, greater access could equate to an additional eight patients surviving to 30-days and six avoiding 30-day readmission. The findings suggest a potential benefit in terms of home discharge and outdoor mobility recovery. CONTRIBUTION OF THE PAPER.

Validity of chronometric TMS for probing the time-course of word production: a modified replication.

In the present study, we used chronometric TMS to probe the time-course of 3 brain regions during a picture naming task. The left inferior frontal gyrus, left posterior middle temporal gyrus, and left posterior superior temporal gyrus were all separately stimulated in 1 of 5 time-windows (225, 300, 375, 450, and 525 ms) from picture onset. We found posterior temporal areas to be causally involved in picture naming in earlier time-windows, whereas all 3 regions appear to be involved in the later time-windows. However, chronometric TMS produces nonspecific effects that may impact behavior, and furthermore, the time-course of any given process is a product of both the involved processing stages along with individual variation in the duration of each stage. We therefore extend previous work in the field by accounting for both individual variations in naming latencies and directly testing for nonspecific effects of TMS. Our findings reveal that both factors influence behavioral outcomes at the group level, underlining the importance of accounting for individual variations in naming latencies, especially for late processing stages closer to articulation, and recognizing the presence of nonspecific effects of TMS. The paper advances key considerations and avenues for future work using chronometric TMS to study overt production.

Dealing with the heterogeneous presentations of freezing of gait: how reliable are the freezing index and heart rate for freezing detection?

BACKGROUND: Freezing of gait (FOG) is an unpredictable gait arrest that hampers the lives of 40% of people with Parkinson's disease. Because the symptom is heterogeneous in phenotypical presentation (it can present as trembling/shuffling, or akinesia) and manifests during various circumstances (it can be triggered by e.g. turning, passing doors, and dual-tasking), it is particularly difficult to detect with motion sensors. The freezing index (FI) is one of the most frequently used accelerometer-based methods for FOG detection. However, it might not adequately distinguish FOG from voluntary stops, certainly for the akinetic type of FOG. Interestingly, a previous study showed that heart rate signals could distinguish FOG from stopping and turning movements. This study aimed to investigate for which phenotypes and evoking circumstances the FI and heart rate might provide reliable signals for FOG detection. METHODS: Sixteen people with Parkinson's disease and daily freezing completed a gait trajectory designed to provoke FOG including turns, narrow passages, starting, and stopping, with and without a cognitive or motor dual-task. We compared the FI and heart rate of 378 FOG events to baseline levels, and to stopping and normal gait events (i.e. turns and narrow passages without FOG) using mixed-effects models. We specifically evaluated the influence of different types of FOG (trembling vs akinesia) and triggering situations (turning vs narrow passages; no dual-task vs cognitive dual-task vs motor dual-task) on both outcome measures. RESULTS: The FI increased significantly during trembling and akinetic FOG, but increased similarly during stopping and was therefore not significantly different from FOG. In contrast, heart rate change during FOG was for all types and during all triggering situations statistically different from stopping, but not from normal gait events. CONCLUSION: When the power in the locomotion band (0.5-3 Hz) decreases, the FI increases and is unable to specify whether a stop is voluntary or involuntary (i.e. trembling or akinetic FOG). In contrast, the heart rate can reveal whether there is the intention to move, thus distinguishing FOG from stopping. We suggest that the combination of a motion sensor and a heart rate monitor may be promising for future FOG detection.
