The Right to Rehabilitation for People With Dementia: A Codesign Approach to Barriers and Solutions.

INTRODUCTION: People with dementia of all ages have a human right to equal access to quality health care. Despite evidence regarding its effectiveness, many people living with dementia are unable to access rehabilitation for promoting function and quality of life. Conducted in Australia, this study was designed to (1) explore barriers to access to dementia rehabilitation and (2) identify solutions that improve access to rehabilitation. METHODS: People living with dementia (n = 5) and care partners (n = 8) and health professionals (n = 13) were recruited nationally. Experience-based codesign across three virtual workshops was used to understand barriers and design solutions to improve access to rehabilitation treatments. Socio-ecological analyses, using the Levesque Access to Health care framework, were applied to findings regarding barriers and to aid selection of solutions. RESULTS: There was high attendance (92.3%) across the three workshops. Barriers were identified at a user level (including lack of knowledge, transport, cost and difficulty navigating the health, aged care and disability sectors) and health service level (including health professional low dementia knowledge and negative attitudes, inequitable funding models and non-existent or fragmented services). Solutions focused on widespread dementia education and training, including ensuring that people with dementia and their care partners know about rehabilitation therapies and that health professionals, aged care and disability co-ordinators know how to refer to and deliver rehabilitation interventions. Dementia care navigators, changes to Australia's public funding models and specific dementia rehabilitation programmes were also recommended. CONCLUSIONS: Barriers to accessing rehabilitation for people with dementia exist at multiple levels and will require a whole-community and systems approach to ensure change. PATIENT OR PUBLIC CONTRIBUTION: People with living experience (preferred term by those involved) were involved at two levels within this research. A Chief Investigator living with dementia was involved in the design of the study and writing of the manuscript. People with living experience, care partners and service providers were participants in the codesign process to identify barriers and design potential solutions.

Changing the focus: Facilitating engagement in physical activity for people living with mild dementia in a local community-Protocol for a pre-post mixed methods feasibility study.

This study aims to address and improve the low physical activity levels among people with mild dementia by implementing a novel shared decision-making and motivational support program, named "Changing the Focus". It will utilise a pre-post mixed methods approach, aiming to recruit 60 community living older people with mild dementia and their care-partners. The shared decision-making process will involve the person living with dementia, their care-partner, and a research therapist, using a purpose-designed discussion tool including factors such as preferred physical activities, health status, local opportunities and program accessibility. This process aims to identify personalised local physical activity opportunities. Participants will be supported with the help of a research therapist to engage in targeted community-based physical activities for 12-months, to progress towards the recommended physical activity guidelines of 150 minutes per week. The intervention provided by the research therapist will include three home visits (baseline, 6- and 12-months) and seven motivational support phone calls (within the first six months). Research therapists may provide additional home visits and support calls as needed. Primary outcomes include program participation (participants living with dementia continuing with the program after 12-months), total physical activity time per week (measured using the Active Australia Survey at baseline, 6- and 12- months) and program acceptability (assessed through semi-structured interviews with participants, care-partners, referrers, and physical activity providers). Secondary outcomes include physical performance, mental health, wellbeing measures, and impact on care-partners (evaluated through physical tests or validated scales at baseline, 6- and 12-months). Other implementation aspects include reach, maintenance, safety (falls, other adverse events) and an economic evaluation. Results will inform feasibility, potential benefits, and challenges associated with this innovative shared decision-making and supported physical activity program for people living with mild dementia. Findings will guide future large-scale studies and contribute to enhancing physical activity opportunities for this population.

Associations between brain structure and dual decline in gait and cognition.

Dual decline in gait and cognition is associated with an increased risk of dementia, with combined gait and memory decline exhibiting the strongest association. To better understand the underlying pathology, we investigated the associations of baseline brain structure with dual decliners using three serial gait speed and cognitive assessments in memory, processing speed-attention, and verbal fluency. Participants (n=267) were categorized based on annual decline in gait speed and cognitive measures. Lower gray and white matter volume and higher white matter hyperintensity volume increased the risk of being a dual decliner in gait and both the memory and processing speed-attention groups (all p < 0.05). Lower hippocampal volume (p = 0.047) was only associated with dual decline in gait and memory group. No brain structures were correlated with dual decline in gait and verbal fluency. These results suggest that neurodegenerative pathology and white matter hyperintensities are involved in dual decline in gait and both memory and processing speed-attention. Smaller hippocampal volume may only contribute to dual decline in gait and memory.

Hand Motor Dysfunction Is Associated with Both Subjective and Objective Cognitive Impairment across the Dementia Continuum.

INTRODUCTION: Motor dysfunction is an important feature of early-stage dementia. Gait provides a non-invasive biomarker across the dementia continuum. Gait speed and rhythm aid risk stratification of incident dementia in subjective cognitive impairment (SCI) and are associated with cognitive domains in mild cognitive impairment (MCI) and dementia. However, hand movement analysis, which may be more accessible, has never been undertaken in SCI and rarely in MCI or dementia. We aimed to address this gap and improve understanding of hand motor-cognitive associations across the dementia continuum. METHODS: A total of 208 participants were recruited: 50 with dementia, 58 MCI, 40 SCI, and 60 healthy controls. Consensus diagnoses were made after comprehensive gold-standard assessments. A computer key-tapping test measured frequency, dwell-time, rhythm, errors, and speed. Associations between key-tapping and cognitive domains and diagnoses were analysed using regression. Classification accuracy was measured using area under receiver operating characteristic curves. RESULTS: Hand frequency and speed were associated with memory and executive domains (p ≤ 0.001). Non-dominant hand rhythm was associated with all cognitive domains. Frequency, rhythm, and speed were associated with SCI, MCI, and dementia. Frequency and speed classified ≥94% of dementia and ≥88% of MCI from controls. Rhythm of the non-dominant hand classified ≥86% of dementia and MCI and 69% of SCI. CONCLUSION: Our findings show hand motor dysfunction occurs across the dementia continuum and, similar to gait, is associated with executive and memory domains and with cognitive diagnoses. Key-tapping performance differentiated dementia and MCI from healthy controls. More research is required before recommending key-tapping as a non-invasive motor biomarker of cognitive impairment.

The Parkinson's Puzzle Box.

INTRODUCTION: Women and those with younger onset Parkinson's Disease (YOPD) are typically diagnosed later and face unique situations and challenges. This essay aims to raise awareness of the difficulties in diagnosing YOPD and the need for a personalised approach to care for women with YOPD. METHODS: Two professional women with YOPD (academic physiotherapist and practicing dentist) and a female neurologist (clinician academic) came together to write a narrative essay on their personal experience and perspectives in relation to women and YOPD. RESULTS: The essay outlines how the experience of diagnosis is likened to a complex puzzle box with many interlocking components that are hidden and difficult to solve. The concerns of the women about their identity, work, family and the future, with most supports targeting those that are older and retired are outlined. CONCLUSION: It is concluded that YOPD is a complex puzzle to solve, but can be done by understanding all the intricate interlocking components of the puzzle and combined with greater awareness could lead to earlier diagnosis and the delivery of successful person-centred care. PATIENT OR PUBLIC CONTRIBUTION: People with lived experience were involved in the essay conception and writing.

Allied health assistant management of people with hip fracture is feasible and may improve patient adherence to hip fracture mobilisation guidelines: a feasibility randomised controlled trial.

OBJECTIVES: Determine the feasibility of allied health assistant (AHA) management of people with hip fracture an acute hospital. DESIGN: Assessor-blind, parallel, feasibility randomised controlled trial with qualitative component. SETTING: Acute orthopaedic ward. PARTICIPANTS: People with surgically-managed hip fracture, who walked independently pre-fracture and had no cognitive impairment. INTERVENTIONS: Rehabilitation from an AHA, under the supervision of a physiotherapist, compared with rehabilitation from a physiotherapist. MAIN OUTCOME MEASURES: Feasibility was evaluated according to focus areas of demand, acceptability, practicality and implementation. Secondary outcomes included estimates of effect of adherence to hip fracture mobilisation guidelines, discharge destination, 30-day readmission, functional activity, and length of stay. RESULTS: Fifty people were allocated to receive rehabilitation from an AHA (n = 25) or physiotherapist (n = 25). AHA rehabilitation had high demand with 60% of eligible participants recruited. Satisfaction with AHA rehabilitation was comparable with physiotherapy rehabilitation (acceptability). The AHA group received an average of 11 min (95% CI 4 to 19) more therapy per day than the physiotherapy group (implementation). The AHA group may have had lower cost of acute care (MD -$3 808 95% CI -7 651 to 35) and adverse events were comparable between groups (practicality). The AHA group may have been 22% (HR 1.22, 95% CI 0.92 to 1.61) more likely to walk on any day and may have had a shorter length of stay (MD -0.8 days, 95% CI -2.3 to 0.7). CONCLUSIONS: AHA management of patients with hip fracture was feasible and may improve adherence to mobilisation guidelines and reduce cost of care and length of stay.

Co-Designed Cardiac Rehabilitation for the Secondary Prevention of Stroke (CARESS): A Pilot Program Evaluation.

Structured health system-based programs, such as cardiac rehabilitation, may reduce the risk of recurrent stroke. This study aimed to co-design and evaluate a structured program of rehabilitation, developed based on insights from focus groups involving stroke survivors and health professionals. Conducted in Tasmania, Australia in 2019, the 7-week program comprised one hour of group exercise and one hour of education each week. Functional capacity (6 min walk test), fatigue, symptoms of depression (Patient Health Questionnaire), and lifestyle were assessed pre- and post-program, with a historical control group for comparison. Propensity score matching determined the average treatment effect (ATE) of the program. Key themes from the co-design focus groups included the need for coordinated care, improved psychosocial management, and including carers and peers in programs. Of the 23 people approached, 10 participants (70% men, mean age 67.4 ± 8.6 years) completed the program without adverse events. ATE analysis revealed improvements in functional capacity (139 m, 95% CI 44, 234) and fatigue (-5 units, 95% CI -9, -1), with a small improvement in symptoms of depression (-0.8 units, 95% CI -1.8, 0.2) compared to controls. The co-designed program demonstrated feasibility, acceptability, and positive outcomes, suggesting its potential to support stroke survivors.

"I'm still in the lap of the gods I don't know whether I'm going to improve or not": listening to people with dementia or cognitive impairment and their support people, talking about inpatient rehabilitation experiences.

PURPOSE: People with dementia often experience poor outcomes in hospital and prolonged lengths of stay. They are sometimes labelled as having "poor rehabilitation potential". This study aimed to understand the inpatient rehabilitation experiences of people with dementia or cognitive impairment, and their support people, to inform future work to improve rehabilitation access and outcomes. MATERIALS AND METHODS: An exploratory qualitative study from an interpretivist perspective. Participants were inpatients of a geriatric rehabilitation unit in Australia, and their chosen support people. Semi-structured interviews were audio-recorded and transcribed. An analytical framework was developed and indexed to the dataset, followed by charting and thematic analysis. RESULTS: Ten people with dementia or cognitive impairment and nine support people participated (n = 19). Four themes were identified representing an interpretation of the analysis intended to inform clinical practice: Support patients to engage in the rehabilitation process; create a hospitable environment; recognise and work with care partners; and ensure staff have adequate dementia knowledge. CONCLUSIONS: Practical, emotional, process-related, and dementia-specific factors may influence the experiences of people living with dementia or cognitive impairment when participating in inpatient rehabilitation. Future research could investigate whether improvements focused on these factors might enhance quality of care for people with dementia.

People living with dementia may require tailored support to engage in the rehabilitation process effectively.Safe, kind, and comfortable environments provide a strong foundation for good rehabilitation care for people with dementia or cognitive impairment.Involving family as care partners may be essential for some people living with dementia.Dementia knowledge for the geriatric rehabilitation workforce may improve clinical outcomes.

Program Evaluation and Refinement of the "Safe Functional Home Exercise" Program for Improving Physical Activity in Older People with Dementia Who Receive Home Care.

INTRODUCTION: People with dementia who receive home care have low levels of physical activity participation. OBJECTIVES: To evaluate and refine a co-designed exercise program for home care clients with dementia, led by trained care support workers. METHODS: An action research cycle whereby support workers, clients and carers (each n = 26) from the "Safe Functional Home Exercise" feasibility study were invited to complete an evaluation survey. Participants rated statements using Likert-style scales on (1) staff training, (2) staff confidence, (3) program support and (4) satisfaction. The participants could provide comments for situations that affected exercise performance, suggested improvements for staff training, program support and exercises. The co-design panel (original program designers) was reconvened to refine the exercise program. RESULTS: Support workers (n = 19), clients (n = 15) and carers (n = 13) returned their surveys. Support workers (74-90%), carers (77-92%) and clients (100%) rated program support positively and were overall satisfied. Support workers (>80%) agreed that the training course was relevant and were confident in delivering the exercises to clients. Situations included "Covid isolation", the client's "poor medical condition" and "mood fluctuations" that made exercising difficult. Improvements included "making a client video" and "providing tips to motivate clients". The co-design panel modified the exercise program. CONCLUSIONS: The "Safe Functional Home Exercise" program is the first exercise program co-designed for people with dementia. It is well accepted by support workers, people with dementia and carers. Utilising support workers to facilitate physical activity participation is potentially low-cost and scalable in home care. Future studies are needed to evaluate the refined program in home care.

Models and approaches for building knowledge translation capacity and capability in health services: a scoping review.

BACKGROUND: Building healthcare service and health professionals' capacity and capability to rapidly translate research evidence into health practice is critical to the effectiveness and sustainability of healthcare systems. This review scoped the literature describing programmes to build knowledge translation capacity and capability in health professionals and healthcare services, and the evidence supporting these. METHODS: This scoping review was undertaken using the Joanna Briggs Institute scoping review methodology. Four research databases (Ovid MEDLINE, CINAHL, Embase, and PsycInfo) were searched using a pre-determined strategy. Eligible studies described a programme implemented in healthcare settings to build health professional or healthcare service knowledge translation capacity and capability. Abstracts and full texts considered for inclusion were screened by two researchers. Data from included papers were extracted using a bespoke tool informed by the scoping review questions. RESULTS: Database searches yielded 10,509 unique citations, of which 136 full texts were reviewed. Thirty-four papers were included, with three additional papers identified on citation searching, resulting in 37 papers describing 34 knowledge translation capability building programmes. Programmes were often multifaceted, comprising a combination of two or more strategies including education, dedicated implementation support roles, strategic research-practice partnerships and collaborations, co-designed knowledge translation capability building programmes, and dedicated funding for knowledge translation. Many programmes utilised experiential and collaborative learning, and targeted either individual, team, organisational, or system levels of impact. Twenty-seven programmes were evaluated formally using one or more data collection methods. Outcomes measured varied significantly and included participant self-reported outcomes, perceived barriers and enablers of knowledge translation, milestone achievement and behaviour change. All papers reported that programme objectives were achieved to varying degrees. CONCLUSIONS: Knowledge translation capacity and capability building programmes in healthcare settings are multifaceted, often include education to facilitate experiential and collaborative learning, and target individual, team, organisational, or supra-organisational levels of impact. Although measured differently across the programmes, the outcomes were positive. The sustainability of programmes and outcomes may be undermined by the lack of long-term funding and inconsistent evaluation. Future research is required to develop evidence-informed frameworks to guide methods and outcome measures for short-, medium- and longer-term programme evaluation at the different structural levels.

Staying Active with Multimorbidity In Acute hospital settings (StAMInA) trial: protocol for a feasibility randomised controlled trial of allied health assistant mobility rehabilitation for patients with multimorbidity.

INTRODUCTION: Key to improving outcomes for patients with multimorbidity is increasing mobility through prescription of a physical activity programme, but this can be difficult to achieve in acute hospital settings. One approach that would assist physiotherapists to increase levels of physical activity is delegation of rehabilitation to allied health assistants. We aim to conduct a randomised controlled trial to determine the feasibility of an allied health assistant providing daily inpatient mobility rehabilitation for patients with multimorbidity. METHODS AND ANALYSIS: Using a parallel group randomised controlled design, participants will be allocated to allied health assistant mobility rehabilitation or physiotherapist mobility rehabilitation. Adult inpatients (n=60) in an acute hospital with a diagnosis of multimorbidity who walked independently preadmission will be included. The experimental group will receive routine mobility rehabilitation, including daily mobilisation, from an allied health assistant under the supervision of a physiotherapist. The comparison group will receive routine rehabilitation from a physiotherapist. Feasibility will be determined using the following areas of focus in Bowen's feasibility framework: Acceptability (patient satisfaction); demand (proportion of patients who participate); implementation (time allied health assistant/physiotherapist spends with participant, occasions of service); and practicality (cost, adverse events). Staff involved in the implementation of allied health assistant rehabilitation will be interviewed to explore their perspectives on feasibility. Secondary outcomes include: Physical activity (daily time spent walking); daily mobilisation (Y/N); discharge destination; hospital readmission; falls; functional activity (Modified Iowa Level of Assistance Scale); and length of stay. Descriptive statistics will be used to describe feasibility. Secondary outcomes will be compared between groups using Poisson or negative binomial regression, Cox proportional hazards regression, survival analysis, linear regression or logistic regression. ETHICS AND DISSEMINATION: Ethics approval was obtained from Peninsula Health (HREC/97 431/PH-2023). Findings will be disseminated in peer-reviewed journals and conference presentations.

Multi-omics and pathway analyses of genome-wide associations implicate regulation and immunity in verbal declarative memory performance.

BACKGROUND: Uncovering the functional relevance underlying verbal declarative memory (VDM) genome-wide association study (GWAS) results may facilitate the development of interventions to reduce age-related memory decline and dementia. METHODS: We performed multi-omics and pathway enrichment analyses of paragraph (PAR-dr) and word list (WL-dr) delayed recall GWAS from 29,076 older non-demented individuals of European descent. We assessed the relationship between single-variant associations and expression quantitative trait loci (eQTLs) in 44 tissues and methylation quantitative trait loci (meQTLs) in the hippocampus. We determined the relationship between gene associations and transcript levels in 53 tissues, annotation as immune genes, and regulation by transcription factors (TFs) and microRNAs. To identify significant pathways, gene set enrichment was tested in each cohort and meta-analyzed across cohorts. Analyses of differential expression in brain tissues were conducted for pathway component genes. RESULTS: The single-variant associations of VDM showed significant linkage disequilibrium (LD) with eQTLs across all tissues and meQTLs within the hippocampus. Stronger WL-dr gene associations correlated with reduced expression in four brain tissues, including the hippocampus. More robust PAR-dr and/or WL-dr gene associations were intricately linked with immunity and were influenced by 31 TFs and 2 microRNAs. Six pathways, including type I diabetes, exhibited significant associations with both PAR-dr and WL-dr. These pathways included fifteen MHC genes intricately linked to VDM performance, showing diverse expression patterns based on cognitive status in brain tissues. CONCLUSIONS: VDM genetic associations influence expression regulation via eQTLs and meQTLs. The involvement of TFs, microRNAs, MHC genes, and immune-related pathways contributes to VDM performance in older individuals.

Physiotherapy students are underprepared to work with people living with dementia: a qualitative study.

OBJECTIVES: To 1) explore physiotherapy students' experience in caring for people with dementia; 2) develop a rich understanding of their perceived preparedness to work with people with dementia upon graduation; and 3) identify opportunities to improve dementia education from the perspectives of students. DESIGN: A qualitative study comprised of semi-structured interviews via web conferencing software. Thematic analysis was undertaken, with themes/subthemes derived and a qualitative framework generated. SETTING: Three Victorian Universities in Australia. PARTICIPANTS: Physiotherapy students of entry-to-professional practice education programs (n = 17; mean age 23.7 years, 65% female), having completed at least 15 weeks of clinical placements. RESULTS: The overarching theme was that students' experience of providing care for people with dementia was variable. The three sub-themes were: 1) students experience significant challenges when working with people with dementia, 2) students experience a range of emotions when working with people with dementia, and 3) the quality of dementia learning experiences during entry-to-professional practice training is mostly inadequate. Students described the importance of the supervisor during clinical placements, and suggested incorporating 'real-life' scenario training in the classroom to assist them learn to manage the challenging symptoms of dementia. CONCLUSION: Physiotherapy students believe that entry-to-practice dementia education is insufficient. These findings have important implications for the future planning and delivery of physiotherapy dementia education. CONTRIBUTION OF THE PAPER.

Virtual emergency care in Victoria: Stakeholder perspectives of strengths, weaknesses, and barriers and facilitators of service scale-up.

BACKGROUND: Virtual emergency services have been proposed as an alternative service model to conventional in-person emergency department attendance. METHODS: Twenty participants were interviewed: 10 emergency medicine physicians, 4 health care consumers, and 6 other health care professionals. Conventional content analysis was performed on the interview transcriptions to identify perceived strengths and weaknesses of the VED, and barriers and facilitators to scaling-up the VED. RESULTS: VEDs are perceived as a convenient approach to provide and receive emergency care while ensuring safety and quality of care, however some patients may still need to attend the ED in person for physical assessments. There is currently a lack of evidence, guidelines, and resources to support their implementation. Most of the potential and existing barriers and facilitators for scaling-up the VED were related to their effectiveness, reach and adoption. Broader public health contextual factors were viewed as barriers, while potential actions to address resources and costs could be facilitators. CONCLUSIONS: VEDs were viewed as a convenient service model to provide care, can not replace all in-person visits. Current policies and guidelines are insufficient for wider implementation. Most of the barriers and facilitators for its scaling-up were related to VED effectiveness and delivery.

Health Literacy predicts incident foot ulcers after 4 years - the SHELLED cohort study.

AIMS/HYPOTHESIS: To determine whether health literacy is associated with an index diabetes-related foot ulcer (DFU). METHODS: The SHELLED Study is a 4-year prospective study of people with diabetes aged over 40 with no history of DFU. The primary outcome was development of a first foot ulcer. Health Literacy was measured using the short form Test of Functional Health Literacy in Adults (s-TOFHLA) and nine domains of the Health Literacy Questionnaire (HLQ). RESULTS: Of 222 participants, 191 (86.0%) completed the study, of whom 13 (5.9%) developed an incident ulcer. In multivariable models, every unit increase in S-TOFHLA was associated with a reduced odds of foot ulcer development by 6% (OR 0.94, 95% CI 0.88 to 0.99). Better scores on two HLQ domains reduced the odds of foot ulcer (actively managing my health (OR 0.23, 95% CI 0.08 to 0.65) and understanding health information well enough to know what to do (OR 0.39, 95% CI 0.19 to 0.78). This was independent of baseline risk for foot disease. CONCLUSIONS/INTERPRETATION: These data provide novel evidence that health literacy is an important clinical risk factor for index foot ulceration. This is an area of potential focus for research and development of educational programs or policy aimed at reducing development of incident foot ulceration.

Investigating the associations between upper limb motor function and cognitive impairment: a scoping review.

Upper limb motor function is a potential new biomarker of cognitive impairment and may aid discrimination from healthy ageing. However, it remains unclear which assessments to use. This study aimed to explore what methods have been used and to describe associations between upper limb function and cognitive impairment. A scoping review was conducted using PubMed, CINAHL and Web of Science. A systematic search was undertaken, including synonyms for key concepts 'upper limb', 'motor function' and 'cognitive impairment'. Selection criteria included tests of upper limb motor function and impaired cognition in adults. Analysis was by narrative synthesis. Sixty papers published between 1998 and 2022, comprising 41,800 participants, were included. The most common assessment tasks were finger tapping, Purdue Pegboard Test and functional tasks such as writing. Protocols were diverse in terms of equipment used and recording duration. Most participants were recruited from clinical settings. Alzheimer's Disease was the most common cause of cognitive impairment. Results were mixed but, generally, slower speed, more errors, and greater variability in upper limb movement variables was associated with cognitive impairment. This review maps the upper limb motor function assessments used and summarises the available evidence on how these associate with cognitive impairment. It identifies research gaps and may help guide protocols for future research. There is potential for upper limb motor function to be used in assessments of cognitive impairment.

Longitudinal associations of objectively measured physical activity and sedentary time with leg muscle strength, balance and falls in middle-aged women.

We examined the longitudinal associations of accelerometer-measured physical activity and sedentary time with leg muscle strength (LMS), balance, and falls in middle-aged women. This was a 5-year cohort study among 308 women aged 36-56 years. We used linear mixed-effects models to examine associations of baseline and change in accelerometer-measured sedentary time, light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) with baseline and 5-year change in LMS and balance (timed up and go test [TUG], functional reach test [FRT], lateral reach test [LRT], and step test [ST]), and negative binomial/Poisson and log-binomial regression as appropriate to assess associations with falls after 5-year follow-up. Greater baseline MVPA was associated with better baseline LMS (ß = 4.65 kg/SD, 95% CI: 1.37, 7.93) and TUG (ß = -0.09 s/SD, 95% CI: -0.18, -0.01) but not with change in them over 5 years. Baseline MVPA was not associated with FRT at baseline but associated with a greater decrease in FRT (ß = -0.87 cm/SD, 95% CI: -1.57, -0.17). Increased MVPA over 5 years was associated with less deterioration in FRT (ß = 0.88 cm/SD, 95% CI: 0.14, 1.61). Increased sedentary time over 5 years was associated with a larger decrease in FRT (ß = -0.82 cm/SD, 95% CI: -1.58, -0.07). Higher baseline LPA was associated with higher falls risk (IRR = 1.27, 95% CI: 1.02, 1.57). Higher baseline MVPA may benefit LMS and balance, while increasing MVPA in the medium term has little effect on change in these outcomes in mid-life. Detrimental association of LPA with falls may be due to greater exposures to environmental hazards.HighlightsOur study for the first time examined the longitudinal associations of objectively measured physical activity and sedentary time with leg muscle strength, balance and falls in middle-aged women.Higher baseline moderate-to-vigorous physical activity (MVPA) may be beneficial for muscle strength and balance at baseline but increasing MVPA in the medium term has little effect on change in LMS or balance outcomes in middle-aged women.Higher baseline light physical activity (LPA) was associated with an increased risk of falls.The detrimental association of LPA with falls may be due to a greater exposure to environmental hazards in midlife, which needs to be clarified in future research.

Using Digital Technology to Quantify Habitual Physical Activity in Community Dwellers With Cognitive Impairment: Systematic Review.

BACKGROUND: Participating in habitual physical activity (HPA) can support people with dementia and mild cognitive impairment (MCI) to maintain functional independence. Digital technology can continuously measure HPA objectively, capturing nuanced measures relating to its volume, intensity, pattern, and variability. OBJECTIVE: To understand HPA participation in people with cognitive impairment, this systematic review aims to (1) identify digital methods and protocols; (2) identify metrics used to assess HPA; (3) describe differences in HPA between people with dementia, MCI, and controls; and (4) make recommendations for measuring and reporting HPA in people with cognitive impairment. METHODS: Key search terms were input into 6 databases: Scopus, Web of Science, Psych Articles, PsychInfo, MEDLINE, and Embase. Articles were included if they included community dwellers with dementia or MCI, reported HPA metrics derived from digital technology, were published in English, and were peer reviewed. Articles were excluded if they considered populations without dementia or MCI diagnoses, were based in aged care settings, did not concern digitally derived HPA metrics, or were only concerned with physical activity interventions. Key outcomes extracted included the methods and metrics used to assess HPA and differences in HPA outcomes across the cognitive spectrum. Data were synthesized narratively. An adapted version of the National Institute of Health Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was used to assess the quality of articles. Due to significant heterogeneity, a meta-analysis was not feasible. RESULTS: A total of 3394 titles were identified, with 33 articles included following the systematic review. The quality assessment suggested that studies were moderate-to-good quality. Accelerometers worn on the wrist or lower back were the most prevalent methods, while metrics relating to volume (eg, daily steps) were most common for measuring HPA. People with dementia had lower volumes, intensities, and variability with different daytime patterns of HPA than controls. Findings in people with MCI varied, but they demonstrated different patterns of HPA compared to controls. CONCLUSIONS: This review highlights limitations in the current literature, including lack of standardization in methods, protocols, and metrics; limited information on validity and acceptability of methods; lack of longitudinal research; and limited associations between HPA metrics and clinically meaningful outcomes. Limitations of this review include the exclusion of functional physical activity metrics (eg, sitting/standing) and non-English articles. Recommendations from this review include suggestions for measuring and reporting HPA in people with cognitive impairment and for future research including validation of methods, development of a core set of clinically meaningful HPA outcomes, and further investigation of socioecological factors that may influence HPA participation.

Identifying Public Healthcare Priorities in Virtual Care for Older Adults: A Participatory Research Study.

There has been increasing adoption and implementation of virtual healthcare in recent years, especially with COVID-19 impacting the world. As a result, virtual care initiatives may not undergo stringent quality control processes to ensure that they are appropriate to their context and meet sector needs. The two objectives of this study were to identify virtual care initiatives for older adults currently in use in Victoria and virtual care challenges that could be prioritised for further investigation and scale-up and to understand why certain virtual care initiatives and challenges are prioritised over others for investigation and scale-up. METHODS: This project used an Emerging Design approach. A survey of public health services in the state of Victoria in Australia was first carried out, followed by the co-production of research and healthcare priorities with key stakeholders in the areas of primary care, hospital care, consumer representation, research, and government. The survey was used to gather existing virtual care initiatives for older adults and any associated challenges. Co-production processes consisted of individual ratings of initiatives and group-based discussions to identify priority virtual care initiatives and challenges to be addressed for future scale-up. Stakeholders nominated their top three virtual initiatives following discussions. RESULTS: Telehealth was nominated as the highest priority initiative type for scaling up, with virtual emergency department models of care nominated as the highest priority within this category. Remote monitoring was voted as a top priority for further investigations. The top virtual care challenge was data sharing across services and settings, and the user-friendliness of virtual care platforms was nominated as the top priority for further investigation. CONCLUSIONS: Stakeholders prioritised public health virtual care initiatives that are easy to adopt and address needs that are perceived to be more immediate (acute more so than chronic care). Virtual care initiatives that incorporate more technology and integrated elements are valued, but more information is needed to inform their potential scale-up.
