Abstract
OBJECTIVE We determined whether an exercise regime comprising high-intensity training, multiplanar trunk movements, and dual-task practice could improve trunk control, balance, functional mobility, and reduce fall risk in patients with hemiplegic stroke. METHODS In this randomized controlled trial, 74 patients (mean age 61.71 years) were randomly assigned to the experimental and comparison groups. Primary outcome was trunk impairment scale (TIS) scores. Secondary outcomes were scores on the Berg balance scale, 10-meter walk test, Timed-up-and-go test, timed-Up-Go-cognitive, and Stroke Impact Scale-16 to measure between-group changes from baseline. We used linear mixed modeling to identify changes over time within and between groups on each scale and whether changes persisted at 6- and 12-month follow-ups. RESULTS We observed significantly increased mean TIS scores from baseline to 3 months post-treatment (7.74); the increased scores were maintained at 6- and 12-month follow-ups (8.60 and 8.43, respectively). In the experimental group, all secondary outcomes showed significant and clinically meaningful results. Fall risk between groups was significantly reduced at 6 and 12 months. CONCLUSIONS Intensive multiplanar trunk movements coupled with dual-task practice promoted trunk control, balance, and functional recovery in patients with stroke, reduced fall risk, and improved independent mobility.Trial registration: #IRCT20200127046275N1.

Ong MF, Soh KL, Saimon R, Wai MW, Mortell M, Soh KG. Fall prevention education to reduce fall risk among community-dwelling older persons: A systematic review. J Nurs Manag 2021; 29:2674-2688. [PMID: 34331491 PMCID: PMC9291009 DOI: 10.1111/jonm.13434] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Accepted: 07/27/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES This review aims to identify types of the existing fall prevention education (FPE) and their effectiveness in promoting fall risk awareness, knowledge and preventive fall behaviour change among community-dwelling older people. BACKGROUND FPE is a cost-effective and helpful tool for reducing fall occurrences. EVALUATION This is a systematic review study using electronic searches via EBSCOHost® platform, ScienceDirect, Scopus and Google Scholar in March 2021. The review protocol was registered with PROSPERO (CRD42021232102). The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement flow chart guided the search strategy. Articles published from January 2010 to March 2021 were included for quality appraisal using the 'Transparent Reporting of Evaluations with Non-randomised Designs' (TREND) and the 'Consolidated Standards of Reporting Trials' (CONSORT) statement for randomised controlled trial studies. KEY ISSUES Six FPE studies selected emphasised on personal health status, exercise and environmental risk factors. These studies reported an increase in fall risk awareness or knowledge and a positive change in fall preventive behaviours. Two studies included nurses as educators in FPE. CONCLUSION FPE evidently improved awareness or knowledge and preventive fall behaviour change among older adults. Nurses are in great potential in planning and providing FPE for older adults in community settings. IMPLICATIONS FOR NURSING MANAGEMENT Expand nurses' roles in fall prevention programmes in community settings by using high-quality and evidence-based educational tools. Highlight the nurse's role and collaborative management in FPE.

Abstract
Background and Objectives: Anticholinergic drug use in the pharmacotherapy of elderly persons is common despite the increased risk of side effects. We examined the prevalence of anticholinergic drug use and total anticholinergic drug burden among patients admitted to an acute care geriatric ward in Poland. Materials and Methods: Cross-sectional study of 329 subjects hospitalized at the geriatric ward. Patient condition was assessed with a comprehensive geriatric assessment. The Anticholinergic Cognitive Burden (ACB) scale was used to estimate the total anticholinergic load. Results: Mean patient age was 79.61 ± 6.82 years. 40.73% of them were burdened with at least one anticholinergic drug. The clinically significant anticholinergic burden was observed in 13.98% of subjects. Patients with dementia, risk of falls, and severe disability had significantly higher total ACB scores compared to other groups. The receiver operating characteristics (ROC) curve revealed that the total ACB score ≥ 1 was significantly associated with dementia and the risk of falls. Total ACB score ≥ 2 was significantly associated with severe disability. Conclusions: Patients admitted to an acute care geriatric ward had an anticholinergic cognitive burden score comparable to other patient populations. We found associations at both low and elevated levels of anticholinergic burden with dementia and risk of falls. At elevated anticholinergic burden levels, we found associations with severe disability. Despite recommendations against the use of anticholinergics in older adults these medications are still commonly prescribed. Further study is necessary to define the characteristics of anticholinergic medication most closely associated with negative outcomes in elderly populations.

Abstract
BACKGROUND Recent falls prevention guidelines recommend early routine fall risk assessment among older persons. OBJECTIVE The purpose of this study was to develop a Falls Screening Mobile App (FallSA), determine its acceptance, concurrent validity, test-retest reliability, discriminative ability, and predictive validity as a self-screening tool to identify fall risk among Malaysian older persons. METHODS FallSA acceptance was tested among 15 participants (mean age 65.93 [SD 7.42] years); its validity and reliability among 91 participants (mean age 67.34 [SD 5.97] years); discriminative ability and predictive validity among 610 participants (mean age 71.78 [SD 4.70] years). Acceptance of FallSA was assessed using a questionnaire, and it was validated against a comprehensive fall risk assessment tool, the Physiological Profile Assessment (PPA). Participants used FallSA to test their fall risk repeatedly twice within an hour. Its discriminative ability and predictive validity were determined by comparing participant fall risk scores between fallers and nonfallers and prospectively through a 6-month follow-up, respectively. RESULTS The findings of our study showed that FallSA had a high acceptance level with 80% (12/15) of older persons agreeing on its suitability as a falls self-screening tool. Concurrent validity test demonstrated a significant moderate correlation (r=.518, P<.001) and agreement (k=.516, P<.001) with acceptable sensitivity (80.4%) and specificity (71.1%). FallSA also had good reliability (intraclass correlation .948; 95% CI .921-.966) and an internal consistency (α=.948, P<.001). FallSA score demonstrated a moderate to strong discriminative ability in classifying fallers and nonfallers. FallSA had a predictive validity of falls with positive likelihood ratio of 2.27, pooled sensitivity of 82% and specificity of 64%, and area under the curve of 0.802. CONCLUSIONS These results suggest that FallSA is a valid and reliable fall risk self-screening tool. Further studies are required to empower and engage older persons or care givers in the use of FallSA to self-screen for falls and thereafter to seek early prevention intervention.

Abstract
Globally, falls are a serious economic and public health concern. While all age groups are impacted by falls, the threats to morbidity and mortality are most severe in older adults. Recent literature has linked hearing loss, and related issues such as an increase in sedentary behaviour, to a greater risk of falls. Therefore, this opinion article aims to raise audiologists’ awareness of falls in ageing patients or clients, and calls for change in terms of having these rehabilitation professionals embrace identification and management of fall risk.

Abstract
Falling is a common incident that affects the health of elder adults worldwide. Postural instability is one of the major contributors to this problem. In this study, we propose a supplementary method for measuring postural stability that reduces doctor intervention. We used simple clinical tests, including the timed-up and go test (TUG), short form berg balance scale (SFBBS), and short portable mental status questionnaire (SPMSQ) to measure different factors related to postural stability that have been found to increase the risk of falling. We attached an inertial sensor to the lower back of a group of elderly subjects while they performed the TUG test, providing us with a tri-axial acceleration signal, which we used to extract a set of features, including multi-scale entropy (MSE), permutation entropy (PE), and statistical features. Using the score for each clinical test, we classified our participants into fallers or non-fallers in order to (1) compare the features calculated from the inertial sensor data, and (2) compare the screening capabilities of the multifactor clinical test against each individual test. We use random forest to select features and classify subjects across all scenarios. The results show that the combination of MSE and statistic features overall provide the best classification results. Meanwhile, PE is not an important feature in any scenario in our study. In addition, a t-test shows that the multifactor test of TUG and BBS is a better classifier of subjects in this study.

Performance and Characteristics of Wearable Sensor Systems Discriminating and Classifying Older Adults According to Fall Risk: A Systematic Review. SENSORS 2021; 21:s21175863.

Abstract
Sensor-based fall risk assessment (SFRA) utilizes wearable sensors for monitoring individuals’ motions in fall risk assessment tasks. Previous SFRA reviews recommend methodological improvements to better support the use of SFRA in clinical practice. This systematic review aimed to investigate the existing evidence of SFRA (discriminative capability, classification performance) and methodological factors (study design, samples, sensor features, and model validation) contributing to the risk of bias. The review was conducted according to recommended guidelines and 33 of 389 screened records were eligible for inclusion. Evidence of SFRA was identified: several sensor features and three classification models differed significantly between groups with different fall risk (mostly fallers/non-fallers). Moreover, classification performance corresponding the AUCs of at least 0.74 and/or accuracies of at least 84% were obtained from sensor features in six studies and from classification models in seven studies. Specificity was at least as high as sensitivity among studies reporting both values. Insufficient use of prospective design, small sample size, low in-sample inclusion of participants with elevated fall risk, high amounts and low degree of consensus in used features, and limited use of recommended model validation methods were identified in the included studies. Hence, future SFRA research should further reduce risk of bias by continuously improving methodology.

Abstract
Background: Falling is a major public health concern of elderly people. We aimed to determine if lean mass and spatiotemporal gait parameters could predict the risk of falling in elderly women and also study the relationships between lean mass and gait characteristics. Methods: Twenty-four community women were prospectively recruited (mean age, 72.30 ± 5.31 years). Lean mass was measured using dual-energy fan-beam X-ray absorptiometry. Gait characteristics were assessed using spatiotemporal analysis. Fall risks were assessed using the Berg Balance Scale (BBS) and the Falls Efficacy Scale-International. Fall histories were recorded. Appropriate statistical analyses were applied to determine lean mass and gait characteristics in predicting the risk of fall and the associations between lean mass and gait characteristics. Results: There were 14 participants (58.33%) with fall histories. Patients with fall histories had a significantly narrower base of support and lower BBS score. However, only the base of support was significantly associated with fall risk (odds ratio, 0.415; p = 0.022). Lean mass was significantly negatively associated with proportion of swing phase and positively associated with proportions of stance and double-support phases. Conclusion: Fall risk among elderly women can be predicted using base of support, where a narrower base predicts a greater fall risk. Although the lean mass was not related to risk of fall, lean mass is still related to some gait characteristics.

Abstract
For humans, the ability to effectively adapt footfall rhythm to perturbations is critical for stable locomotion. However, only limited information exists regarding how dynamic stability changes when individuals modify their footfall rhythm. In this study, we recorded 3D kinematic activity from 20 participants (13 males, 18–30 years old) during walking on a treadmill while synchronizing with an auditory metronome sequence individualized to their baseline walking characteristics. The sequence then included unexpected temporal perturbations in the beat intervals with the subjects required to adapt their footfall rhythm accordingly. Building on a novel approach to quantify resilience of locomotor behavior, this study found that, in response to auditory perturbation, the mean center of mass (COM) recovery time across all participants who showed deviation from steady state (N = 15) was 7.4 (8.9) s. Importantly, recovery of footfall synchronization with the metronome beats after perturbation was achieved prior (+3.4 [95.0% CI +0.1, +9.5] s) to the recovery of COM kinematics. These results highlight the scale of temporal adaptation to perturbations and provide implications for understanding regulation of rhythm and balance. Thus, our study extends the sensorimotor synchronization paradigm to include analysis of COM recovery time toward improving our understanding of an individual’s resilience to perturbations and potentially also their fall risk.

Abstract
In the prospective, randomized, controlled multicenter study, 100 patients who were clinically diagnosed with sarcopenia were assigned to either a home-based exercise group or a control group. The home-based training program included exercises with gradually increasing intensity comprising posture, stretching and upper- and lower-extremity muscle-strengthening exercises, balance and coordination exercises, and gait training. Before and 3 months after the exercise program, all the patients were evaluated. The 6-min walking test and Berg Balance Scale scores increased significantly after 3 months in the home-based exercise group compared with the controls. There was also a significant decrease in timed up and go test scores and a significant improvement in quality of life in the exercise group compared with the control group. Our findings indicated that a home-based exercise program can have a positive effect on physical function, balance, and quality of life in patients with sarcopenia.

Abstract
The purposes of this study were to compare the differences in physical fitness between community-dwelling older women fallers and non-fallers, with and without a risk of falling, and to investigate the relation between physical fitness and falling risk factors. This study was a secondary data analysis from a community- and exercise-based fall-prevention program. Baseline assessments pertaining to body weight and height, self-reported chronic diseases, the 12-item fall risk questionnaire (FRQ), senior fitness test, single-leg stand test, and handgrip strength test were extracted. Participants (n = 264) were classified into fallers and non-fallers, and sub-classified according to the risk of falling (FRQ ≥4 and <4). While controlling for the effect of age, body mass index (BMI), and multimorbidity, one-way analysis of covariance indicated that older women with a risk of falling showed poorer performances of the 8-foot up-and-go, 2-min step and 30-s chair stand compared with those without a risk of falling, regardless of the history of falls. Additionally, weaker grip strength was found in non-fallers with falling risk. Some significant, but low-to-moderate, correlations were found between physical fitness tests and fall risk factors in the FRQ, particularly in gait/balance problem and leg muscle weakness. Proactive efforts are encouraged to screen and manage deterioration in the identified physical fitness.

Abstract
Evidence on effective fall prevention strategies for community-dwelling elders with dementia is limited, although these elders are at high risk of falling. Informal caregivers may play an essential role in managing fall risk for elders with dementia. Thus, understanding caregiver's experiences is critically important. This systematic review aims to (a) identify caregivers' perceptual, emotional and behavioural responses to fall risk in elders with dementia and (b) examine the outcomes and effects of caregiver behavioural responses. A mixed methods systematic review of 10 databases (PubMed, PsycINFO, CINAHL, Social Service Abstracts, Social Work Abstracts, EMBASE, Web of Science, Scopus, Cochrane Library and TRIP Medical Database) was conducted. We searched English language, peer-review articles (January 1, 1985-March 20, 2020) that met the predefined inclusion/exclusion criteria. Study quality was assessed using the Mixed Methods Appraisal Tool. Data were analysed using thematic synthesis techniques. Twenty-nine studies were included. Six analytic themes were generated concerning caregivers' perceptual, emotional and behavioural responses: (a) fear of the negative health consequences of falls; (b) limited insights into factors contributing to falls; (c) varying expectations of managing fall risk; (d) multi-level efforts; (e) struggling with responsibilities; and (f) inaction and withdrawal. The findings about the outcomes and effects of caregivers' behaviours were synthesised into three analytic themes: (a) multi-faceted outcomes; (b) uncertain and inconsistent evidence; and (c) unclear associations. The study generated new insights in understanding caregivers' responses of fall risk among community-dwelling elders with dementia and identified significant gaps in examining the impact of caregivers' responses and what shapes these responses. Investment in understanding caregivers' perspectives will inform future interventions and policies to reduce negative outcomes for elders, caregivers and care systems.

Abstract
INTRODUCTION Fall risk is an acknowledged but relatively understudied concern for older patients undergoing shoulder surgery. The cause is multifactorial, and it includes advanced age, impaired upper extremity function, use of shoulder abduction braces, and postoperative use of opioid medications. No previous study has examined preoperative fall risk in patients undergoing elective shoulder surgery. Previous literature looking at fall risk in elective orthopedic procedures has predominantly focused on falls occurring in the hospital setting, although falls have also been shown to occur in the outpatient setting. Gait speed and Timed Up and Go (TUG) are well-researched functional measures in the aging population with established cutoff scores indicating increased fall risk. The purpose of this study was to quantify gait speed and TUG scores in a series of patients who were scheduled to undergo either rotator cuff repair (RCR) or total shoulder arthroplasty (TSA) in order to assess overall risk of fall in these populations. METHODS A total of 198 patients scheduled for TSA or RCR surgery were evaluated preoperatively from multiple outpatient physical therapy clinics within Greenville, South Carolina. The TUG score (>14 seconds considered high fall risk) and 10 Meter Walk test (<0.7 m/s considered high risk for falls) were recorded for each patient. Patient-reported outcomes were also collected, including Veteran's Rand 12 Physical Component and Mental Component Scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, and the Single Assessment Numeric Evaluation. RESULTS Patients undergoing TSA (n = 80; 65.4 ± 11.4 years) were older than those undergoing RCR (n = 118; 59.0 ± 14.2 years). Fifty-nine percent of all patients were classified as being a high risk for falls based on gait speed <0.7 m/s. Patients in the TSA group were more likely to display preoperative fall risk compared to patients in the RCR group (62% vs. 38%; χ2 = 8.9, P = .03). There were no significant differences in ambulatory status, Veteran's Rand 12 Physical Component and Mental Component Scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, or Single Assessment Numeric Evaluation scores between groups (P = .11). DISCUSSION Both patient groups demonstrated a high rate of fall risk in preoperative evaluation. Patients undergoing TSA more often displayed fall risk compared with patients undergoing RCR. Although patients in the TSA group were older, there was no association between age or ambulatory status and fall risk. CONCLUSION Our results suggest that fall risk screening may be important for patients undergoing TSA and RCR surgeries. The higher fall risk in the TSA group may be an important consideration as this procedure shifts toward outpatient status.

Abstract
Background: Peripheral neuropathy (PN) can result in either partial or complete loss of distal sensation resulting in an increased fall risk. Walkasins® uses a shoe insert to detect the magnitude and direction of sway and sends signals to a leg unit that provides sensory balance cues. The objective of this case report is to describe the long-term influence of the Walkasins® lower limb sensory neuroprosthesis on balance and gait for an individual with diabetic PN. Case Description: A 51-year-old male with a 3-year history of PN and a 10-year history of type II diabetes mellitus was fitted bilaterally with Walkasins® and utilized them 8-10 hours/day for more than 2 years. Although, vibration and tactile sensation thresholds were severely impaired at his 1st metatarsophalangeal joint and the lateral malleolus bilaterally he could perceive tactile stimuli from the Walkasins® above the ankles. Outcomes: Following Walkasins® use, his Activities-specific Balance Confidence Scale (ABC) scores improved from 33 to 80%. His mean Vestibular Activities of Daily Living (VADL) scores decreased from 3.54 to 1. His Functional Gait Assessment (FGA) scores increased from 13/30 to 28/30 and his miniBESTest scores improved from 15/28 to 26/28. Gait speed increased from 0.23 to 1.5 m/s. The patient described a decrease in pain and cramping throughout his lower extremities and an increase in function. Discussion: Gait and balance improved with the use of the Walkasins® and participation in a wellness program. This improvement suggests that the use of sensory substitution devices, such as the Walkasins®, may replace sensory deficits related to gait and balance dysfunction experienced by patients with PN. Further research is needed to determine if other patients will have a similar response and what the necessary threshold of sensory function is to benefit from use of the Walkasins®.

Abstract
BACKGROUND Falls are a major health problem in older persons but are still under-diagnosed and challenging to prevent. Current guidelines do not target high-risk populations, especially people living with dementia. In France, people with neurocognitive disorders are mainly referred to memory clinics (MCs). OBJECTIVE We aimed to survey the routine practice of physicians working in MCs regarding fall risk assessment. METHODS We conducted a cross-sectional survey in France from January to May 2019 among physicians working in MCs, through an anonymous online questionnaire: twenty-seven questions about the physician's background and their practice of fall risk assessment, especially use of clinical and paraclinical tools. We compared the results according to the age and the specialty of the physician. RESULTS We obtained 171 responses with a majority of women (60%) and geriatricians (78%). All age classes and all French regions were represented. Most of respondents (98.8%) stated that they address gait and/or falls in outpatient clinic and 95.9%in day hospitals. When asked about how they assess fall risk, fall history (83%) and gait examination (68.4%) were the most widely used, while orthostatic hypotension (24%) and clinical standardized tests (25.7%) were less common. Among standardized tests, One-leg Balance, Timed Up and Go Test, and gait speed measurements were the most used. Geriatricians had more complete fall risk assessment than neurologists (e.g., 56%versus 13%for use of standardized tests, p < 0.0001). CONCLUSION Almost all physicians addressed the question of fall in MC, but practices are widely heterogeneous. Further investigations are needed to standardize fall risk assessment in MCs.

Empirical Mode Decomposition-Derived Entropy Features Are Beneficial to Distinguish Elderly People with a Falling History on a Force Plate Signal. ENTROPY 2021; 23:e23040472. [PMID: 33923557 PMCID: PMC8072535 DOI: 10.3390/e23040472] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Revised: 04/01/2021] [Accepted: 04/12/2021] [Indexed: 11/19/2022]
Abstract
Fall risk prediction is an important issue for the elderly. A center of pressure signal, derived from a force plate, is useful for the estimation of body calibration. However, it is still difficult to distinguish elderly people’s fall history by using a force plate signal. In this study, older adults with and without a history of falls were recruited to stand still for 60 s on a force plate. Forces in the x, y and z directions (Fx, Fy, and Fz) and center of pressure in the anteroposterior (COPx) and mediolateral directions (COPy) were derived. There were 49 subjects in the non-fall group, with an average age of 71.67 (standard derivation: 6.56). There were also 27 subjects in the fall group, with an average age of 70.66 (standard derivation: 6.38). Five signal series—forces in x, y, z (Fx, Fy, Fz), COPX, and COPy directions—were used. These five signals were further decomposed with empirical mode decomposition (EMD) with seven intrinsic mode functions. Time domain features (mean, standard derivation and coefficient of variations) and entropy features (approximate entropy and sample entropy) of the original signals and EMD-derived signals were extracted. Results showed that features extracted from the raw COP data did not differ significantly between the fall and non-fall groups. There were 10 features extracted using EMD, with significant differences observed among fall and non-fall groups. These included four features from COPx and two features from COPy, Fx and Fz.

Abstract
BACKGROUND All healthcare institutions prioritize falls as a major safety issue. Falls are of particular concern on inpatient oncology units where patients are substantially at risk for injury related to falls. OBJECTIVES This article describes a multifaceted fall-prevention initiative that can be implemented on oncology units using evidence-based interventions in the key areas of communication, toileting, and hourly rounding. The Visual Rounding Tool for communication around hourly rounding and proactive toileting is also introduced. METHODS Based on a root cause analysis and literature review, the inpatient oncology unit-based committee launched a three-intervention initiative, carried out during three consecutive months, to address patient falls. FINDINGS Fall rates decreased using the three- intervention initiative. Systematic improvement in processes enabled an increased occurrence of communication between nurses and assistive personnel, increased use of the Visual Rounding Tool for proactive toileting and hourly rounding, and a significant but short-lived decrease in call light use.

Abstract
Slowed gait is one of the strongest predictors of fall risk in older adults. The present study investigated whether gait speed mediated the relationship between depression and fall history in 147 older adults presenting to a memory clinic for cognitive complaints. Depression, cognitive status, gait speed, and number of falls within the last year were the primary measures. Results revealed fallers, relative to non-fallers, had slower gait speed and higher depression scores. As hypothesized, analyses using the PROCESS macro found that gait mediated the relationship between depression and fall history. Additionally, the combination of depression and mild cognitive impairments (MCI) associated with a significantly greater likelihood of falling. Our findings indicate that combined depression and MCI have additive effects on fall risk, likely through the destabilizing effect of slowed gait on balance. Better understanding the underlying pathophysiology involved in MCI and depression-related gait disturbances may lead to improved intervention targets for fall risk prevention.

Abstract
BACKGROUND/OBJECTIVE Falls cause significant problems for older adults. Sedentary time is associated with lower physical function and could increase the risk for falls. DESIGN Prospective study. SETTING Sites across the United States. PARTICIPANTS Older women (N = 5,545, mean age 79 years) from the Women's Health Initiative Objective Physical Activity and Cardiovascular Health study. MEASUREMENTS Accelerometers worn at the hip for up to 1 week collected measures of daily sedentary time and the mean sedentary bout duration, a commonly used metric for sedentary accumulation patterns. For up to 13 months after accelerometer wear, women reported daily whether they had fallen on monthly calendars. RESULTS In fully adjusted models, the incident rate ratios (95% confidence interval) for quartiles 1 (lowest), 2, 3, and 4 of sedentary time respectively were 1.0 (ref.), 1.07 (0.93-1.24), 1.07 (0.91-1.25), and 1.14 (0.96-1.35; P-trend = .65) and for mean sedentary bout duration was 1.0 (ref.), 1.05 (0.92-1.21), 1.02 (0.88-1.17), and 1.17 (1.01-1.37; P-trend = .01), respectively. Women with a history of two or more falls had stronger associations between sedentary time and falls incidence compared with women with a history of no or one fall (P for interaction = .046). CONCLUSIONS Older women in the highest quartile of mean sedentary bout duration had a significantly increased risk of falling. Women with a history of frequent falling may be at higher risk for falling if they have high sedentary time. Interventions testing whether shortening total sedentary time and/or sedentary bouts lowers fall risk are needed to confirm these observational findings.

Abstract
The Centers for Disease Control and Prevention (CDC) Stopping Elderly Accidents, Deaths & Injuries (STEADI) toolkit is a national effort to prevent falls among older adults. Studies have been conducted on implementation of the STEADI, but no studies have investigated older adults' adherence to or perceptions of fall prevention recommendations delineated within the STEADI algorithm. Semistructured interviews were conducted with a purposive sample of older adults 6 months after attending a falls risk assessment. Seventy-nine percent accurately recalled their fall risk, 57% followed one or more recommendations, and 32% did not recall at least one recommendation correctly. The most common recommendation recalled and adhered to was exercise. No participants recalled or adhered to recommendations including medication review, taking time changing positions, vision check, podiatrist visit, or physical therapy. Thirty-two percent fell. Of these, 55.6% did not follow any recommendations. Interview transcripts were analyzed using comparative methodology following the tenets of thematic analysis. Three themes emerged: participating in fall prevention, barriers to following recommendations, and providers can encourage people to prevent falls. An unexpected facilitator to participation in fall prevention efforts emerged-older adults' perception that they were positively influencing society by participating in research and working with students and the university. This finding provides an opportunity for providers of health education to address the growing public health issue of falls among older adults while also creating opportunities for students to engage in community service and interdisciplinary service learning.

Abstract
BACKGROUND The prevalence of falls affects the wellbeing of aging adults and places an economic burden on the healthcare system. Integration of wearable sensors into existing fall risk assessment tools enables objective data collection that describes the functional ability of patients. In this study, supervised machine learning was applied to sensor-derived metrics to predict the fall risk of patients following total hip arthroplasty. METHODS At preoperative, 2-week, and 6-week postoperative appointments, patients (n = 72) were instrumented with sensors while they performed the timed-up-and-go walking test. Preoperative and 2-week postoperative data were used to form the feature sets and 6-week total times were used as labels. Support vector machine and linear discriminant analysis classifier models were developed and tested on various combinations of feature sets and feature reduction schemes. Using a 10-fold leave-some-subjects-out testing scheme, the accuracy, sensitivity, specificity, and area under the receiver-operator curve (AUC) were evaluated for all models. RESULTS A high performance model (accuracy = 0.87, sensitivity = 0.97, specificity = 0.46, AUC = 0.82) was obtained with a support vector machine classifier using sensor-derived metrics from only the preoperative appointment. An overall improved performance (accuracy = 0.90, sensitivity = 0.93, specificity = 0.59, AUC = 0.88) was achieved with a linear discriminant analysis classifier when 2-week postoperative data were added to the preoperative data. CONCLUSION The high accuracy of the fall risk prediction models is valuable for patients, clinicians, and the healthcare system. High-risk patients can implement preventative measures and low-risk patients can be directed to enhanced recovery care programs.

Abstract
Background: While physical therapy may help improve function and quality of life in patients with neurofibromatosis (NF), a standard of care remains to be established. This case report describes the physical therapy management of an individual with NF who was at high fall risk.Case Description: A 61-year-old male with NF and multiple comorbidities was determined to be at high fall risk by the Dynamic Gait Index, Berg Balance Scale, and Modified Falls Efficacy Scale. Deficits included coordination and strength which limited his ability to ascend and descend stairs or walk on uneven terrain. This reduced his independence at home and in his rural community. Interventions incorporated components of hip and trunk coordination, and addressed balance, strength, and functional mobility.Outcomes: The patient scored above the cutoff for high fall risk on all outcome assessments.Discussion: This case report describes physical therapy management to reduce fall risk for an individual with NF. Due to the limited research on NF, the treatment plan was developed using evidence-based practice for fall-risk reduction in other neurological disorders.

Abstract
Cannabis is one of the most common drugs in the United States and is the third most prevalent substance consumed by adults aged 50 years and older. Normal aging is associated with physiological changes that make older adults vulnerable to impaired function and geriatric conditions (e.g., falls, cognitive impairment). However, the impact of medical cannabis use on fall risk in older adults remains unexplored. The purpose of this study was to investigate if cannabis use in older adults influences fall risk, cognitive function, and motor function. It was hypothesized that older chronic cannabis users would perform worse than non-users on gait, balance, and cognitive tests. Sixteen older adults, split into cannabis Users and age- and sex-matched Non-Users groups (n = 8/group), participated in the study. The results indicate a higher fall risk, worse one leg standing balance performance, and slower gait speed in Users vs. Non-Users. No significant differences in cognitive function were found. Thus, chronic cannabis use was purported to exacerbate the poorer balance control and slower gait velocity associated with normal aging. Future mechanistic (e.g., neuroimaging) investigations of the short- and long-term effects of using a variety of cannabis products (e.g., THC/CBD ratios, routes of administration) on cognitive function, motor function, and fall incidence in older adults are suggested.

Abstract
BACKGROUND Emerging evidence suggests that multicomponent exercise provides greater benefits for physical and cognitive function than single component exercise. However, few studies have been conducted to determine these effects in older adults with mild cognitive impairment (MCI) and findings have been less conclusive. It has been reported that older women have a greater risk of falls and a higher incidence of dementia than men. OBJECTIVES To examine the effects of multicomponent exercise on cognitive performance and fall risk in older women with MCI. DESIGN An experimental design comparing the exercise and control groups. SETTING AND PARTICIPANTS Forty community-dwelling older women with MCI were allocated to the exercise (n = 20) and control (n = 20) groups. INTERVENTION Twelve weeks of multicomponent exercise program (aerobic, resistance, and balance exercise) 60 mins/day, 3 days/week. MEASUREMENT Cognitive performance including the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Trail Making Test (TMT) and fall risk including the Timed Up and Go (TUG) single-, dual-task, and Physiological Profile Assessment (PPA) were administered before and after the 12-week exercise program. RESULTS At the end of the 12-week training, participants in the exercise group had a significantly greater improvement in TMT part A (p < 0.05), TUG dual-task (p < 0.05), and PPA composite score (p < 0.05) when compared to the control group. The exercise group also demonstrated significant improvement in TUG dual-task, PPA composite score, PPA subcomponents including postural sway and reaction time when compared to baseline (p < 0.05). In contrast, at 12-week, the control group showed a decline in TUG dual-task performance as compared to baseline (p < 0.05). CONCLUSION The 12-week multicomponent exercise improved attention, dual-task ability, and reduced risk of falling in older women with mild cognitive impairment.

Abstract
Background Dynamic balance is associated with fall risk. The aim of this study is to explore the effects of galvanic vestibular stimulation with very low intensity direct current (dcGVS) on dynamic balance. Methodology We used a rocker force platform for assessing the dynamic balance performance. Center-of-pressure (COP) coordinates were acquired and decomposed to rambling (RA) and trembling (TR). We measured sway parameters, including length, average speed, and average range, affected by dcGVS at 0.01 mA with eyes open (EO) and eyes closed (EC). Results We assessed 33 young healthy subjects and found that all sway parameters were shorter in the EO condition, indicating a better dynamic balance performance. dcGVS significantly improved the dynamic balance performance both in EO and EC conditions. All the sway parameters in COP in EO were significantly shorter than those in EC, indicating a better dynamic balance performance in EO. In EO, RA had greater improvement rates than TR. In EC, only average speed had a greater improvement rate in RA, whereas length and average range had greater improvement rates in TR. These results indicate a different modulation model between EO and EC. Conclusion These findings indicate that very low intensity dcGVS improved the sway parameters of dynamic balance in young healthy subjects. Moreover, our results suggest different dynamic balance control models between having EO and EC. The mechanisms of these phenomena caused by very low intensity dcGVS require further investigation.
