Exploring Demographic and Cognitive Predictors of Self-Management in Quasi-Randomized Fall Prevention Intervention for Older Adults With and Without Traumatic Brain Injury.

Changes in health behavior are key to maintaining health, safety, and independence of older adults. The purpose of this study was to explore factors impacting training in self-management and behavior change in older adults with and without traumatic brain injury (TBI), informing efforts to improve safety and independent function. Forty-one older adults, 19 with TBI, completed a self-regulation intervention (mental contrasting with implementation intentions; MCII) to promote fall prevention behavior change. Participant outcomes were related to single and recurring behavior changes; implementation outcomes were measured as modifications to treatment. Although participants with TBI performed more poorly on tests of neurocognitive function, there were no differences in behavior change rates following MCII, suggesting the treatment worked similarly for participants with and without TBI. Across both groups, those with higher executive function scores were more likely to complete recurring behavior changes. Participants with higher stress, higher Fall Risk Scores, or history of TBI were more likely to need modifications to treatment. This quasi-experimental pilot study describes cognitive and psychosocial predictors that may be critical for participation and success in health behavior change and self-management of fall prevention for older adults with and without TBI.

Exercise for fall prevention in older adults

Background: Global population aging has significantly increased fall-related incidents among older adults, which is associated with major health risks and challenges for healthcare systems. Falls are a leading cause of injury, disability, and mortality in South Korea, which has shown rapid expansion of the elderly population. Development of effective fall-prevention strategies, including exercise-based interventions is important to address this issue.Current Concepts: Exercise-based fall prevention programs include several key types such as strength and functional movement training and balance exercises. Strength training includes resistance exercises and weightbearing activities to enhance muscle strength, which is essential for stability and fall prevention. Balance exercises improve stability and coordination, including standing on one leg and heel-to-toe walking. Functional movement training includes exercises that simulate daily activities and help individuals to improve their ability to safely perform routine tasks. Programs such as the Otago Exercise Program integrate these elements and offer a comprehensive approach to fall prevention. Such regimens combined with training in safe falling techniques are important to reduce fall risk and improve outcomes. Assessment tools, including the timed up-and-go and senior fitness tests, are useful to identify at-risk individuals and tailor interventions accordingly.Discussion and Conclusion: An effective fall prevention exercise program requires a multifaceted approach that combines various exercise types and focuses on improving muscle strength, balance, flexibility, and functional skills, as well as safe falling and floor recovery techniques. Tailoring these interventions to individual needs and regular risk assessments can enhance their usefulness.

Integrating Fall Prevention Strategies into EMS Services to Reduce Falls and Associated Healthcare Costs for Older Adults.

The purpose of this study is to detail the implementation of fall prevention initiatives through emergency medical services (EMS) and associated outcomes. Paramedics with MedStar Mobile Healthcare utilized the Stopping Elderly Accidents, Deaths, and Injuries (STEADI) fall prevention model to screen and direct intervention through 9-1-1 emergency response, High Utilization Group (HUG), and 30-day Hospital Readmission Avoidance (HRA) programs. Outcomes from 9-1-1 calls measured the number of older adults screened for falls and identified risk factors. The HUG and HRA programs measured change in quality of life with EuroQol-5D, referral service utilization, falls, emergent healthcare utilization, and hospital readmission data. Analysis included costs associated with reduced healthcare usage. Emergency paramedics provided fall risk screening for 50.5% (n=45,090) of adults aged 65 and older and 59.3% were at risk of falls, with 48.1% taking medications known to increase the risk of falls. Services provided through the HUG and HRA programs, along with additional needed referral services, resulted in a 37.2% reduction in fall-related 9-1-1 calls and a 29.5% increase in overall health status related to quality of life. Analysis of the HUG program revealed potential savings of over $1 million with a per-patient enrolled savings of $19,053. The HRA program demonstrated a 16.4% hospital readmission rate, in comparison to a regional average of 30.2%, and a cost-savings of $4.95 million or $15,618 per enrolled patient. Implementation of the STEADI model into EMS services provides an effective and cost-saving model for addressing fall prevention for older adults, provides meaningful and impactful improvement for older adults, and could serve as a model for other EMS programs.

Enhancing Footwear Safety for Fall Prevention in Older Adults: A Comprehensive Review of Design Features.

Falls are a global concern affecting people of all ages; however, older adults are particularly vulnerable to age-related factors and foot-related issues. Footwear is critical for preventing falls, as it provides stability and protection against slips, trips, and falls (STFs). However, a significant gap exists in the systematic exploration of the safety aspects of footwear design for fall prevention in older adults. This comprehensive review applied a meticulous search strategy encompassing prominent databases, including Google Scholar, ScienceDirect, SCOPUS, MEDLINE, ResearchGate, and PubMed. This review synthesized and analyzed existing research to bridge knowledge gaps and provide insights into optimal footwear choices for older adults in terms of design features such as fit, fixation, heel height, collar height, slip resistance, and sole/insole hardness. The results underscore the importance of specific design features for preventing falls among older adults. A proper fit, secure fixation, appropriate heel and collar heights, slip resistance, and sole/insole hardness significantly contributed to fall prevention. These findings offer valuable guidance for optimizing footwear designs to enhance comfort, stability, and safety in the daily lives of older individuals. This comprehensive review fills a critical knowledge gap regarding the safety of footwear designs for fall prevention in older adults. The identified design features play a vital role in reducing the risk of falls and offer practical recommendations for the development of safer footwear. Ultimately, this study contributes to the existing knowledge base and supports efforts to prevent STFs in older adults through improved footwear design.

Factors affecting home environmental safety management for fall prevention for older adults in northern Thailand

BackgroundFalls among older adults affect physical and mental health, disability, death, and quality of life. Home environmental safety management helps to reduce the risk of falls among older adults. This analytical cross-sectional study aimed to determine factors affecting home environmental safety management for fall prevention for older adults in northern Thailand.MethodsThe study sample included 328 relatives who looked after older adults in their families in Phitsanulok Province, northern Thailand. They were randomly selected by a multistage sampling technique. Data were collected by a self-administered questionnaire consisting of 7 parts: (1) sociodemographic characteristics, (2) knowledge about home environmental safety management, (3) perceived susceptibility of falls, (4) perceived severity of falls among older adults, (5) perceived self-efficacy of home environmental safety management, (6) perceived outcome of home environmental safety management, and (7) home environmental safety management. Frequencies, percentages, means, standard deviations, and multiple regression analysis were employed for data analysis.ResultsThe majority of participants (60.4%) had high scores for home environmental safety management for fall prevention for older adults (scores of 14–20). Factors that significantly affected home environmental safety management included perceived severity of falls among older adults (β = 0.323), perceived self-efficacy of home environmental safety management (β = 0.311), the elderly family member having fallen in the past year (β = 0.217), being a grandchild of an older adult (β = -0.143), perceived outcome of home environmental safety management (β = 0.142), and being widowed, divorced or separated (β = -0.096). These 6 factors explained 35.1% of home environmental safety management for fall prevention for older adults.ConclusionRelatives who look after older adults should be educated about the perceived severity of falls among older adults, perceived self-efficacy, and perceived outcome of home environmental safety management. The focus should be on grandchildren of older adults and those who are widowed, divorced or separated to understand how home environmental safety management is important to prevent falls and their consequences among older adults.

Postural adaptations within normalized stability between older adults with and without chronic low back pain.

Adaptations of dynamic balance performance are related to sway excursions in older adults with chronic low back pain (LBP). However, there is a lack of understanding on postural control within different thresholds of radius from the center of pressure (COP). This study was conducted to compare the normalized stability based on the time-in-boundary (TIB) during repeated unilateral limb standing trials between subjects with and without chronic LBP. There were 26 older adults with LBP and 39 control subjects who completed three trials of repeated unilateral limb standing on a force plat. The TIB based on the seven thresholds was analyzed, and the groups demonstrated a significant interaction on thresholds for TIB (F = 8.76, p = 0.01). The TIB was significantly different in the 10 mm (F = 4.01, p = 0.04), 15 mm (F = 5.21, p = 0.03), and 20 mm (F = 4.48, p = 0.04) radius of thresholds only in the second trial. However, there was no group difference on TIB at the first and third trials due to potential compensatory and/or adaptive reactions to avoid fall risks. The LBP group lacked postural stability within the thresholds less than a 20 mm radius at the second trial of unilateral standing. The significant group interaction with the thresholds indicates an adaptation strategy on sway thresholds. This postural reaction from repeated trials should be considered with sway excursion adjustments and fall prevention in older adults with LB.

Feasibility, effectiveness and acceptability of two perturbation-based treadmill training protocols to improve reactive balance in fall-prone older adults (FEATURE): protocol for a pilot randomised controlled trial

IntroductionPerturbation-based balance training (PBT) targets the mechanism of falls (eg, slipping, tripping) to specifically train the recovery actions needed to avoid a fall. This task-specific training has shown great promise...

Perspectives: How to Apply Motivational Interviewing for Older Adult Fall Prevention

More than one in three adults age ≥65 fall each year, and fall-related deaths are increasing in the United States. Falls risks can be reduced when older adults are able to engage in series of behavior changes to reduce their high fall risk factors. However, older adults perceive their fall risks to be lower than clinically indicated and adherence rates for fall prevention recommendations are suboptimal. Motivational interviewing (MI), a validated patient-centered behavior change communication approach, is ideal for addressing these gaps and facilitating older adults’ engagement in fall prevention. The goal of this paper is to present practical tips to apply MI for fall prevention for clinicians who may not be familiar with MI. We draw on our experience from providing MI sessions to high fall risk older adults within a randomized controlled trial. We describe how we delivered MI sessions and practical lessons learned from this experience. We present how basic MI skills can be used for fall prevention using a case study, how an older adult may move through Stages of Change for fall prevention, and how to address strongly held beliefs about fall prevention.

Evaluation of a novel technology-supported fall prevention intervention – study protocol of a multi-centre randomised controlled trial in older adults at increased risk of falls

BackgroundIncreasing number of falls and fall-related injuries in an aging society give rise to the need for effective fall prevention and rehabilitation strategies. Besides traditional exercise approaches, new technologies show promising options for fall prevention in older adults. As a new technology-based approach, the hunova robot can support fall prevention in older adults.The objective of this study is to implement and evaluate a novel technology-supported fall prevention intervention using the hunova robot compared to an inactive control group. The presented protocol aims at introducing a two-armed, multi-centre (four sites) randomised controlled trial, evaluating the effects of this new approach on the number of falls and number of fallers as primary outcomes.MethodsThe full clinical trial incorporates community-dwelling older adults at risk of falls with a minimum age of 65 years. Including a one-year follow-up measurement, all participants are tested four times. The training programme for the intervention group comprises 24-32 weeks in which training sessions are scheduled mostly twice a week; the first 24 training sessions use the hunova robot, these are followed by a home-based programme of 24 training sessions. Fall-related risk factors as secondary endpoints are measured using the hunova robot. For this purpose, the hunova robot measures the participants’ performance in several dimensions. The test outcomes are input for the calculation of an overall score which indicates the fall risk. The hunova-based measurements are accompanied by the timed-up-and-go test as a standard test within fall prevention studies.DiscussionThis study is expected to lead to new insights which may help establish a new approach to fall prevention training for older adults at risk of falls. First positive results on risk factors can be expected after the first 24 training sessions using the hunova robot. As primary outcomes, the number of falls and fallers within the study (including the one-year follow-up period) are the most relevant parameters that should be positively influenced by our new approach to fall prevention. After the study completion, approaches to examine the cost-effectiveness and develop an implementation plan are relevant aspects for further steps.Trial registrationGerman Clinical Trial Register (DRKS), ID: DRKS00025897.

Compensatory stepping responses during real-life falls in older adults

BackgroundLaboratory studies of postural responses suggest that stepping is a common strategy for balance recovery. Yet little is known about the frequency and characteristics of stepping responses during real-life falls in older adults. Research questions(1) Among falls experienced by older adults in long-term care (LTC), what is the prevalence of attempts to recover balance by stepping? (2) How often are steps aligned to the direction of the fall? (3) Do the prevalence and characteristics of steps associate with intrinsic and situational factors? MethodsWe collected and analyzed video footage of 1516 falls experienced by 515 residents of LTC (of mean age 82.7 years). Using generalized estimating equations, we tested whether the prevalence, direction and size of steps associated with sex, age, fall direction, activity at the time of falling, cause of imbalance, and holding or grasping objects. ResultsStepping after imbalance was observed in 76% of falls, and 80% of these cases involved multiple steps. The direction of steps aligned with the initial fall direction in 81% of cases. The size of the first step was less than one-half foot length in 64% of cases. Secondary steps tended to be similar in size to the first step. Steps were more common for falls during walking than standing, and for sideways falls. Steps were less common in falls involving held objects, and steps were less likely to be aligned with the fall direction when reach-to-grasp responses were observed. SignificanceOlder adults in LTC tended to respond to falls with multiple compensatory steps. Steps were tailored to the direction of the fall, but small in size (less than one-half foot length in size). Exercise programs for fall prevention in older adults should focus on increasing step size to enhance the effectiveness of step recovery responses.

Best-Practice Exercise Interventions to Prevent Falls in Older Adults

Globally, falls are a major public health problem that can cause morbidity, including fracture and disability, and mortality in older people. Exercise therapy is widely recommended, and it is frequently regarded as the gold-standard strategy for preventing falls in both community-dwelling and institutionalized older people. This review synthesizes published findings on feasible, low-technology, low-cost equipment, and easy-to-follow effective fall prevention interventions in healthy older adults. According to the evidence presented in this review, home-based balance and strengthening training programs utilizing low-cost equipment such as foam balance pads, steps, dumbbells, and elastic bands are more cost-effective and feasible exercises for fall prevention in older adults who do not have cognitive impairments. The Otago program, Lifestyle Approach to reducing Falls through Exercise (LiFE) program, and Ossébo exercise program are some of the best-known examples. Physiotherapists will benefit from this updated review, which rates different simple fall prevention programs used worldwide for both community-dwelling and institutionalized older adults.

The role of motivation factors in exergame interventions for fall prevention in older adults: A systematic review and meta-analysis

Balance disorders and falls are common in the elderly population. Regular balance exercises are an evidence-based physical intervention to prevent falls in older adults, while patient motivation and adherence are important factors for intervention outcome. Exergames are a relatively new, alternative intervention for physical rehabilitation as they improve balance and strength in older adults. The aims of this systematic review and meta-analysis were to assess the (1) effect of motivation factors as per the Capability, Opportunity and Motivation model of Behavior change (COM-B) on the effectiveness of exergame interventions in healthy older adults, (2) effectiveness of exergames to improve balance in older healthy adults and, (3) impact of exergames on cognitive outcomes. Results show that motivation and capability components influence the general outcome of the exergame training. Motivational factors should thus be considered when setting-up an exergame intervention. Furthermore, exergame intervention appears to be a promising training method in comparison to traditional exercise training. However, exergame training in itself might not be sufficient to improve fall risk and cognitive performance.

Combined Use of Transcutaneous Electrical Nerve Stimulation and Short Foot Exercise Improves Navicular Height, Muscle Size, Function Mobility, and Risk of Falls in Healthy Older Adults.

Electrical stimulation is an established method that is used to improve muscle strength. The present study compared changes in the navicular drop test (NDT), muscle size, the five times sit to stand (5TSTS) test, the timed up and go (TUG) test, and the risk of falls in response to transcutaneous electrical nerve stimulation (TENS) plus short foot exercise (SFE) and SFE alone in 68 healthy elderly participants aged 65–75 years. Participants were randomly assigned to two groups: TENS plus SFE and SFE alone (with sham TENS). Measurements of NDT, muscle size, 5TSTS, TUG, and risk of falls were made before and after 4 weeks of training. The NDT was significantly improved by a median of 0.31 mm in the TENS plus SFE group and 0.64 mm in the SFE alone group (p < 0.001). Similarly, there was a significant improvement in Falls Efficacy Scale International (FES-I), 5TSTS, and TUG for both groups (p < 0.001). The abductor hallucis muscle size increased by 0.23 cm2 in the TENS plus SFE group and 0.26 cm2 in the SFE alone group (p < 0.001). There were no significant differences between the two groups for any variables (p > 0.05) except TUG, which showed a greater improvement in the TENS plus SFE group (p = 0.008). Our findings demonstrated that TENS plus SFE and SFE alone improved intrinsic foot muscle size. However, TENS plus SFE tended to improve NDT more than SFE alone, particularly in cases of severe muscle weakness. Thus, the combined use of TENS plus SFE could be recommended for muscle strengthening and balance programs for fall prevention in older adults.

Balance Exercise Circuit for fall prevention in older adults: a randomized controlled crossover trial.

Objectives:This study aimed to assess the immediate and short-term effects of the Balance Exercise Circuit (BEC) on muscle strength, postural balance, and quality of life, with the aim of preventing falls in older adults.Methods:Twenty-two volunteers participated in this randomized controlled crossover study. Group A performed BEC training in the initial 3 months and received no intervention in the following 3 months. Group B received no intervention during the first 3 months and then participated in BEC training for the next 3 months. In addition, participants were followed for an additional 3 months. Muscle strength, postural balance, functional mobility, and quality of life were assessed, respectively, using an isokinetic dynamometer, force platform, TUG test, and the WHOQOL.Results:After 3 months of training, Group A presented improved balance and rate of force development (RFD), while Group B presented improvements in RFD, TUG performance, and WHOQOL physical and psychological domains. Regarding the short-term effects, the participants maintained the training effects in WHOQOL balance, RFD, and the social domain. In addition, the number of falls decreased during follow-up.Conclusion:The BEC intervention improved muscle strength, postural balance, and quality of life in older adults, in addition to reducing the risk of falls.Trial registration:Brazilian Registry of Clinical Trials (ReBEC) - RBR-5nvrwm.

Accidental Fall Death in McLean County: Examining Variables in Community-Dwelling Older Adults.

Fall risk assessment is a complex phenomenon involving several risk factors, including an individual's balance and mobility status, chronic health conditions, visual impairment, hearing deficits, environmental hazards (e.g., loose rugs, clutter), and being homebound or semi-homebound. Comprehensive fall risk assessment is the cornerstone of fall prevention in older adults throughout the community. The current study was based on secondary data and sought to examine variables associated with death due to accidental fall in a rural, midwestern county in Illinois, and to heighten awareness for consistent screening and risk assessment in older adults residing in the community. Results illustrated that among community-dwelling older adults with accidental falls, blunt injury or subdural hematoma had significantly fewer days until death than a fracture. [Journal of Gerontological Nursing, 48(6), 26-32.].

Mobility screening for fall prediction in the Canadian Longitudinal Study on Aging (CLSA): implications for fall prevention in the decade of healthy ageing.

BackgroundGuidelines for fall prevention in older adults recommend mobility screening for fall risk assessment; however, there is no consensus on which test to use and at what cutoff. This study aimed to determine the accuracy and optimal cut-off values of commonly used mobility tests for predicting falls in the Canadian Longitudinal Study on Aging (CLSA).MethodsMobility tests at baseline included the Timed Up and Go (TUG), Single Leg Stance (SLS), chair-rise and gait speed. Inclusion criteria were: age ≥ 65 years and meeting first-level fall screening criteria (i.e. history of a fall or mobility problem) at baseline. Accuracy of fall prediction at 18-months for each test was measured by the area under the receiver operating curve (AUC).ResultsOf 1,121 participants that met inclusion criteria (mean age 75.2 ± 5.9 years; 66.6% women), 218 (19.4%) reported ≥one fall at 18 months. None of the tests achieved acceptable accuracy for identifying individuals with ≥one fall at follow-up. Among women 65–74 and 75–85 years, the TUG identified recurrent fallers (≥two falls) with optimal cut-off scores of 14.1 and 12.9 s (both AUCs 0.70), respectively. Among men 65–74 years, only the SLS showed acceptable accuracy (AUC 0.85) for identifying recurrent fallers with an optimal cutoff of 3.6 s.ConclusionsOur findings indicate that commonly used mobility tests do not have sufficient discriminability to identify fallers in a population-based sample of community-dwelling older adults. The TUG and SLS can identify recurrent fallers; however, their accuracy and cut-off values vary by age and sex.

Does the time of day differently impact the effects of an exercise program on postural control in older subjects? A pilot study

BackgroundThe time of day that people exercise can potentially influence the efficiency of exercises for fall prevention in older adults. The present pilot study was conducted to explore the feasibility and effects of morning versus afternoon exercising on postural control in institutionalized older adults.MethodsNine older adults completed a 3-month multimodal exercise program in its entirety (14 participants were recruited at the beginning and were initially randomly separated into two groups). One group exercised in the morning (ME; n = 4) and the other in the afternoon (AE; n = 5). Postural control was assessed with a force platform at pre and post-intervention at the following times: 8 a.m., 11 a.m., 2 p.m. and 5 p.m.ResultsPostural control significantly improved only in the AE group post-intervention. Improvements in postural control in the AE group were mainly observed in the morning.ConclusionsThe afternoon would be the best period to implement exercise sessions dedicated to improve postural control in older subjects with benefits mainly observed in the morning. Further studies are needed with a larger sample in order to confirm these results.

Fall prevention in hospitals and nursing homes: Clinical practice guideline.

BackgroundFalls and their consequences are particularly common in older adults in hospitals and long‐term care (LTC) facilities.AimTo avoid falls and their consequences, and provide nurses with an overview of all relevant research literature on fall prevention, and a practice guideline on fall prevention in older adults was developed.MethodsThe development process included a systematic literature review to identify systematic reviews and primary studies on the topic of fall prevention, an assessment of the study quality, the preparation of meta‐analyses to summarize the results, and the application of the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to grade the scientific literature. The guideline panel and an external multidisciplinary team graded the recommendations using the Delphi method. In addition, the panel and team formulated expert opinions.ResultsA total of 79 randomized controlled trials on fall prevention were identified, which formed the basis of the recommendations. Strongly recommended measures for both settings included multifactorial interventions, professionally supported body exercise interventions, and education and counselling interventions. The panel and team did not recommend the use of a specific assessment tool for fall risk assessment, low‐floor beds in hospitals, or body exercise interventions in frail residents.Linking Evidence to ActionDuring the development of this guideline, particular attention was paid to collecting evidence‐based knowledge relevant to practice. By applying the recommendations, the outlined nursing care is justified, enabling healthcare personnel to achieve the overriding goal of providing optimal care to persons at risk of falling. Evidence for several fall prevention interventions was graded as very low. Sound intervention studies are necessary to strengthen the confidence in the evidence for low‐floor beds, alarm sensor systems, medication review, and staff education in hospitals.
