Abstract
Falls are the leading cause of injury and hospitalization for older adults in Canada and the second leading cause of unintentional injury deaths worldwide. For people living with dementia (PLWD), falls have an even greater impact, but the standard testing methods for fall risk screening and assessment are often not practical for this population. The purpose of this scoping review is to identify and summarize recent research, practice guidelines and gray literature which have considered fall risk screening and assessment for PLWD. Database search results revealed a dearth in the literature that can support researchers and healthcare providers when considering which option/s are the most suitable for PLWD. Further primary studies into the validity of using the various tests with PLWD are needed if researchers and healthcare providers are to be empowered via the literature and clinical practice guidelines to provide the best possible fall risk care for PLWD.

A secondary analysis of a randomised controlled trial to investigate the effect of Tai Chi on the instrumented timed up and go test in people with mild to moderate dementia. Aging Clin Exp Res 2021; 33:2175-2181. [PMID: 33141417 PMCID: PMC8302509 DOI: 10.1007/s40520-020-01741-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 10/13/2020] [Indexed: 02/05/2023]
Abstract
Background Previous research has identified that Tai Chi is effective for reducing risk of falls and improving timed up and go scores. However, our previous research identified no-significant difference in time to complete the timed up and go test following a Tai Chi intervention in people with dementia. Aim To conduct a secondary analysis to extend our understanding of the effect of Tai Chi on the instrumented Timed Up and Go test. Methods This is a secondary analysis of a randomised controlled trial set in the community. People with dementia, recruited from NHS databases, memory clinics, local charities and self-referral across the south of England, received either 20 weeks of Tai Chi plus normal care or normal care. Outcomes were assessed using the instrumented Timed Up and Go test, completed at baseline and after 6 months. Results From 83 people with dementia volunteering for the study, 67 complete datasets were available for analysis. Within-group pairwise comparison across time revealed no-significant gains for any of the instrumented Timed Up and Go variables, and no-significant difference for between-group pairwise comparisons. Discussion This suggests that Tai Chi had no effect on the instrumented Timed Up and Go in people with dementia. This lack of effect may be due to the lack of specificity of the training stimulus to the outcome measure. Conclusion Tai Chi had no effect on any instrumented Timed Up and Go variables, suggesting Tai Chi may not be best placed to enhance the sub-elements of the instrumented Timed Up and Go to reduce fall risk among community-dwelling people with dementia. Clinical trial registration number: NCT02864056.

Abstract
BACKGROUND AND PURPOSE The instrumented Timed Up and Go test (iTUG) affords quantification of the subelements of the Timed Up and Go test to assess fall risk and physical performance. A miniature sensor applied to the back is able to capture accelerations and velocities from which the subelements of the iTUG can be quantified. This study is the first to compare iTUG performance between people with dementia (PWD) and their age-matched caregivers. The aims of this study were to explore how age moderates the differences in performance on the iTUG between PWD and their informal caregivers. METHODS Eight-three community-dwelling older PWD and their informal caregivers were recruited for this cross-sectional, observational study. Participants were grouped by age: younger than 70 years, 70 to 79 years, and 80 years and older. Participants wore an inertial sensor while performing the iTUG in their home. The performance of the subelements sit-to-stand, walking, and turning were captured through an algorithm converting accelerations and velocities into performance metrics such as duration and peak velocity. Performance for PWD was compared with caregivers for each age-matched group, and multiple regression models incorporating age, gender, and presence or absence of dementia were computed. RESULTS People with dementia took longer to turn in the younger than 70-year group, suggesting this may be an early indicator of functional decline in this age group. People with dementia took longer to complete the whole iTUG compared with caregivers in the 70- to 79-year-old group. In the 80+-year-old group, PWD took longer to complete both walking phases, sit-to-stand, and the full iTUG along with displaying slower turning velocity. Multiple regression models illustrated that gender failed to contribute significantly to the model, but age and presence of dementia explained around 30% of the variance of time to complete walking phases, total iTUG, and turning velocity. CONCLUSIONS Differences were evident in performance of the iTUG between PWD and caregivers even after controlling for age. Age moderates the differences observed in performance.

J Clin Lipidol 2020; 14:507-514. [PMID: 32571729 DOI: 10.1016/j.jacl.2020.05.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 05/15/2020] [Accepted: 05/17/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Statins are associated with muscle-related adverse events, but few studies have investigated the association with fall-related hospitalizations among residents of long-term care facilities (LTCFs). OBJECTIVE The objective of the study is to investigate whether statin use is associated with fall-related hospitalizations from LTCFs. METHODS A case-control study was conducted among residents aged ≥65 years admitted to hospital from 2013 to 2015. Cases (n = 332) were residents admitted for falls and fall-related injuries. Controls (n = 332) were selected from patients admitted for reasons other than cardiovascular and diabetes. Cases and controls were matched 1:1 by age (±2 years), index date of admission (±6 months), and sex. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using conditional logistic regression, after considering for history of falls, hypertension, dementia, functional comorbidity index, polypharmacy (≥9 regular preadmission medications), and fall-risk medications. Subanalyses were performed for individual statins, dementia, and statin intensity. RESULTS Overall, 43.1% of cases and 27.1% of controls used statins. Statins were associated with fall-related hospitalizations (aOR = 2.24, 95% CI 1.56-3.23), in particular simvastatin (aOR = 2.26, 95% CI 1.22-4.20) and atorvastatin (aOR = 2.08, 95% CI 1.33-3.24). Statins were associated with fall-related hospitalizations in residents with (aOR = 2.34, 95% CI 1.33-4.11) and without dementia (aOR = 2.30, 95% CI 1.46-3.63). There was no association between statin intensity and fall-related hospitalizations (aOR = 0.78, 95% CI 0.43-1.40). CONCLUSION This study suggests a possible association between statin use and fall-related hospitalizations among residents living in LTCFs. However, there was minimal evidence for a relationship between statin intensity and fall-related hospitalizations. Further research is required to substantiate these hypothesis-generating findings.

Abstract
Abstract Objective: to investigate the frequency of falls and clinical and physical-functional factors associated with falls, and the accuracy of such factors to identify the risk of falling in cognitively impaired older adults. Method: a cross-sectional study with cognitively impaired older adults was carried out using the Mini-Mental State Examination. The dependent variable was a history of falls in the previous six months. The independent variables were self-reported mental confusion, hearing and visual impairment, physical fatigue, muscle weakness, dizziness, body imbalance, insecurity when walking, diagnosed depression, hospitalizations, continuous use medications (form from study used), muscle mass (calf circumference) and handgrip strength (dynamometry), functional capacity (Pfeffer) and mobility (SAM-Br). Descriptive statistics were applied. The groups were compared using the Mann Whitney U test, the risk factors were identified by univariate and multivariate logistic regression, and the area under the ROC curve (AUC) was calculated for the associated factors. Results: 216 cognitively impaired older adults were included in the analysis, 41.7% of whom were fallers. Multivariate regression analyzes indicated that complaints of visual impairment (OR=2.8; p=0.015) and body imbalance (OR=2.7; p=0.004), and greater medication use (OR=1.1; p=0.038) were associated with a history of falls. The AUC found poor accuracy for quantity of medications as a screening tool for fallers (AUC=0.6 [0.5; 0.7]; p=0.028). Conclusion: cognitively impaired older adults had a high frequency of falls. Complaints of visual impairment, body imbalance and polypharmacy were predictors of falls. The early assessment of these factors can contribute to the identification of cognitively-impaired older adults at risk of falling in clinical practice and research.

Abstract
Hip fracture and dementia rates increase with age, and both groups of patients suffer increased morbidity and mortality and functional impairment. The management of these patients is a challenge for the orthogeriatric and rehabilitation team process, as despite the evidence on the benefit, the results analysed are still worse than in patients without cognitive impairment. For this reason, and due to the limitation in health resources, many of them have problems in accessibility to them, or are limited to a less intense rehabilitation. There are insufficient studies on the best rehabilitation interventions in this group of patients, but it is suggested: 1) to use a multidisciplinary rehabilitation model adapted to the patient with dementia, and 2) to redefine results of the rehabilitation of these patients not only in terms of functional improvement, without highlighting other concepts, such as quality of life, decrease in complications or improved social support.

Abstract
Background Falls are a public health issue for the older adult population and more so for people with dementia (PWD). Compared with their cognitively intact peers, PWD are at higher risk of falls and injurious falls. This randomised controlled trial aims to test the clinical and cost effectiveness of Tai Chi to improve postural balance among community-dwelling PWD and to assess the feasibility of conducting a larger definitive trial to reduce the incidence of falls among PWD. Methods A 3-centre parallel group randomised controlled trial with embedded process evaluation. One hundred and fifty community-dwelling dyads of a person with dementia and their informal carer will be recruited and assessed at baseline and at six-month follow-up. Dyads will be randomised in a 1:1 ratio to either usual care or usual care plus a Tai Chi intervention for 20 weeks. The Tai Chi intervention will consist of weekly classes (45 min’ Tai Chi plus up to 45 min for informal discussion, with up to 10 dyads per class) and home-based exercises (20 min per day to be facilitated by the carer). Home practice of Tai Chi will be supported by the use of behaviour change techniques with the Tai Chi instructor at a home visit in week 3–4 of the intervention (action planning, coping planning, self-monitoring, and alarm clock reminder) and at the end of each class (feedback on home practice). The primary outcome is dynamic balance measured using the Timed Up and Go test, coinciding with the end of the 20-week intervention phase for participants in the Tai Chi arm. Secondary outcomes for PWD include functional balance, static balance, fear of falling, global cognitive functioning, visual-spatial cognitive functioning, quality of life, and falls. Secondary outcomes for carers include dynamic balance, static balance, quality of life, costs, and carer burden. Discussion This trial is the first in the UK to test the effectiveness of Tai Chi to improve balance among PWD. The trial will inform a future study that will be the first in the world to use Tai Chi in a trial to prevent falls among PWD. Trial registration NCT02864056.

Abstract
Background People diagnosed with dementia are at greater risk of falls. Given the increasing incidence of dementia globally, high quality and methodologically rigorous research is needed to inform evidence-based practice initiatives. Aims To describe the published literature related to describing, reducing or preventing fall incidences for people living with dementia including: (1) trends in the total number of intervention and non-intervention studies between 1997 and 2016; (2) the methodological quality of identified intervention studies; and (3) the effectiveness of interventions designed to reduce the incidence of falls among people living with dementia. Methods A systematic review of five databases was conducted to identify studies reporting any aspect of falls incidence for people with a diagnosis of dementia. Studies meeting the eligibility criteria were coded as intervention or non-intervention studies. Intervention studies were assessed using Cochrane’s Effective Practice and Organisation of Care tool. Data about the effectiveness of interventions meeting Effective Practice and Organisation of Care criteria were extracted. Results Seventy-two eligible studies were identified; 57 were non-intervention studies, and 15 were intervention studies. The number of published studies increased between 1997 and 2016, peaking in 2013 ( n = 10). Of the 15 intervention studies, seven studies met Effective Practice and Organisation of Care design criteria with one study rated low risk on all eight Effective Practice and Organisation of Care risk of bias domains. One high-risk exercise-based intervention study demonstrated a significant reduction in falls among people living with dementia. Conclusions There is currently insufficient evidence to endorse any intervention to reduce falls for people living with dementia in any setting. More high-quality intervention studies are needed.

Abstract
OBJECTIVE: To evaluate the feasibility and preliminary effects of a simplified 10-step Tai-chi programme to improve the motor performance of people with dementia. DESIGN: A two-arm, single-blinded cluster randomized controlled trial, registered with ClinicalTrials.gov (NCT03341091). SETTING: Community health centres. PARTICIPANTS: Twenty-six dyads of people with dementia and their family caregivers were recruited, with mean (SD) ages of 82.2 (7.43) and 51.3 (18.97), respectively. INTERVENTIONS: The experimental group underwent a 16 week 10-step simplified Tai-chi training programme, with additional measures to enhance engagement. The control group joined recreational activities organized by the centres. MAIN OUTCOME MEASURE(S): The feasibility assessment included recruitment, attrition, adherence to, and engagement in the Tai-chi programme. The preliminary effects were assessed by the participants' performance in mobility tests. RESULTS: Preliminary feasibility was established, with an acceptable recruitment rate of 58% (26 out of 45 assessed dyads) and a high attendance rate of 81% (25.88 out of 32 Tai-chi sessions). There was positive engagement in the training sessions, and no adverse incidents. However, five participants withdrew from the Tai-chi group, for a high attrition rate of 38%, and the mean home practice time decreased between weeks 8 and 16. In most of the motor performance tests, a slight but insignificant improvement was observed in the Tai-chi group compared to the control group. CONCLUSION: A tailored Tai-chi programme for people with dementia using a dyadic approach has been found to be feasible. However, stronger support must be provided to family caregivers to improve the participants' sustained participation.

Abstract
Falls are common among older inpatients and remain a great challenge for hospitals. Despite the relevance of physical impairments to falls, the prognostic value of performance-based functional measures for in-hospital falls and injurious falls remains unknown. This study aimed to determine the predictive ability and accuracy of various functional tests administered at or close to admission in a geriatric hospital to identify in-hospital fallers and injurious fallers. In this prospective study, conducted in a geriatric hospital in Geneva, Switzerland, 807 inpatients (mean age 85.0 years) were subjected to a battery of functional tests administered by physiotherapists within 3 days (interquartile range 1 to 6) of admission, including Short Physical Performance Battery (SPPB), simplified Tinetti, and Timed Up and Go tests. Patients were prospectively followed up for falls and injurious falls until discharge using mandatory standardized incident report forms and electronic patients' records. During a median length of hospital stay of 23 days (interquartile range 14 to 36), 329 falls occurred in 189 (23.4%) patients, including 161 injurious falls of which 24 were serious. In-hospital fallers displayed significantly poorer functional performances at admission on all tests compared with non-fallers (p < 0.001 for all). In multivariate analysis controlling for age, sex, previous falls, and fall as cause of admission, poorer functional performances on all functional tests predicted in-hospital falls and injurious falls (p < 0.001 for all). The SPPB only significantly predicted serious injurious falls (adjusted odds ratio [OR] = 0.76; 95% confidence interval [CI] 0.60-0.96) and fractures (adjusted OR = 0.76; 95% CI 0.59-0.98). In conclusion, poor functional performances, as assessed by SPPB, are independent predictors of in-hospital falls, injurious falls, and fractures in patients admitted to a geriatric hospital. These findings should help to design preventive strategies for in-hospital falls and support the adoption of objective performance-based functional measures into routine hospital practice. © 2018 American Society for Bone and Mineral Research.

Abstract
Purpose: People with dementia fall more often than cognitively healthy older adults, but their risk factors are not well understood. A review is needed to determine a fall risk profile for this population. The objective was to critically evaluate the literature and identify the factors associated with fall risk in older adults with dementia. Methods: Articles published between January 1988 and October 2014 in EMBASE, PubMed, PsycINFO, and CINAHL were searched. Inclusion criteria were participants aged 55 years or older with dementia or cognitive impairment, prospective cohort design, detailed fall definition, falls as the primary outcome, and multi-variable regression analysis. Two authors independently reviewed and extracted data on study characteristics, quality assessment, and outcomes. Adjusted risk estimates were extracted from the articles. Results: A total of 17 studies met the inclusion criteria. Risk factors were categorized into demographic, balance, gait, vision, functional status, medications, psychosocial, severity of dementia, and other. Risk factors varied with living setting and were not consistent across all studies within a setting. Conclusion: Falls in older adults with dementia are associated with multiple intrinsic and extrinsic risk factors, some shared with older adults in general and others unique to the disease. Risk factors vary between community- and institution-dwelling samples of adults with dementia or cognitive impairment.

Abstract
Ambulation with a mobility aid is a unique real-life situation of multi-tasking. These simultaneous motor tasks place increased demands on executive function in healthy young and older adults, but the demands have not been evaluated in people with Alzheimer's disease (AD). Mobility problems are common among adults with AD, leading to provision of a mobility aid to optimize independent activity. The study objectives were: (i) to determine the dual-task cost (DTC) associated with the use of a mobility aid in straight and complex path walking, and (ii) to evaluate the association between executive function and ambulation with a mobility aid in older adults with AD and age-sex matched cognitively normal controls. Fourteen people (mean age±SD, 72.6±9.9years) with a diagnosis of probable AD (MMSE range 12-25) and controls (mean age±SD, 72.9±9.5) walked at a self-selected pace and using a 4-wheeled walker in a 6m straight path and a Figure of 8 Test. Ambulation with the walker in a straight path produced a low DTC that was not different between the groups. Ambulation with the 4-wheeled walker in the complex path produced a significantly different DTC in the group with AD at -38.1±23.5% compared to -19.7±21.4% (p=0.041). Lower scores on executive function were associated with longer times across test conditions. Ambulation with a 4-wheeled walker, in particular maneuvering around obstacles, requires greater attentional costs in dementia. Future research should explore the timing for safely introducing mobility aids in AD and the role of improving executive function.

Abstract
This systematic review aims to report the effectiveness of interventions based on exercise and/or physical environment for reducing falls in cognitively impaired older adults living in long-term care facilities. In July 2014, a literature search was conducted using main databases and specialised sources. Randomised controlled trials assessing the effectiveness of fall prevention interventions, which used exercise or physical environment among elderly people with cognitive impairment living in long-term care facilities, were selected. Two independent reviewers checked the eligibility of the studies, and evaluated their methodological quality. If it was adequate, data were gathered. Fourteen studies with 3,539 participants using exercise and/or physical environment by a single or combined approach were included. The data gathered from studies that used both interventions showed a significant reduction in fall rate. Further research is needed to demonstrate the effectiveness of those interventions for preventing falls in the elderly with cognitive impairment living in long-term care establishments.

Abstract
With hip fracture and dementia increasing in incidence in the global ageing population, there is a need for the development of specific procedures targeting optimal treatment outcomes for these patients. This paper looks primarily at the factors that limit access to subacute rehabilitation services as a growing body of evidence suggests that access to timely inpatient rehabilitation increases functional outcomes for patients both with dementia and without. Information was gathered by searching electronic data bases (SCOPUS, Medline, CINAHL, Health Source Nursing/Academic Addition, Psychinfo and the Cochrane Library) for relevant articles using the search terms dementia OR Alzheimer* AND hip fracture AND subacute rehabilitation OR convalescence for the period 2005–2015. Abstracts were scanned to identify articles discussing eligibility and access. A total of nine papers were identified that directly addressed this topic. Other papers discussing success or failure of rehabilitation and improved models of care were also reviewed. Barriers to access discussed in the literature include information management, management of comorbidities, attitudes, resource availability, and the quality of evidence and education. By identifying these factors we can identify strategic points of intervention across the trajectory of prevention, treatment and rehabilitation that may improve outcomes for this growing group of vulnerable patients. Emerging best practice for these patients is also discussed.
