Measuring fear of falling among high-risk, urban, community-dwelling older adults

Assessment tools of the fear of falling: A scoping review

AIM

To comprehensively evaluate and synthesize fear of falling assessment tools and their psychometric properties.

METHODS

The literature in PubMed, Web of Science Core Collection, Cochrane Library, Embase, Google Scholar, CNKI, Wanfang, VIP, and CBM was systematically searched, and the search period was from the establishment of the database to September 1, 2023, and updated on September 1, 2024.

RESULTS

A total of 104 documents covering 19 assessment tools were included. Of the 19 instruments, the Falls Efficacy Scale-International was the most widely used and had been tested for reliability and validity in different countries and populations. A total of 18 studies focused on tool development and validation, and the remaining 86 were related to tool validation.

CONCLUSION

Scientific and reliable assessment instruments for FOF are an important part of future targeted intervention research. The future research direction of tools should be based on local demographic characteristics and qualitative interview results, combined with objective quantitative indicators measured by professional instruments.

Cognitive functions explain discrete parameters of normal walking and dual-task walking, but not postural sway in quiet stance among physically active older people

BACKGROUND

Postural control is dependent on the central nervous system's accurate interpretation of sensory information to formulate and execute adequate motor actions. Research has shown that cognitive functions are associated with both postural control and fall risk, but specific associations are not established. The aim of this study was to explore how specific components of everyday postural control tasks are associated with both general and specific cognitive functions.

METHODS

Forty-six community-dwelling older adults reported their age, sex, physical activity level, falls and fall-related concerns. The following cognitive aspects were assessed: global cognition, executive functions, processing speed and intraindividual variability. Postural control was quantified by measuring postural sway in quiet stance, walking at a self-selected pace, and walking while performing a concurrent arithmetical task. Separate orthogonal projections of latent structures models were generated for each postural control outcome using descriptive and cognitive variables as explanatory variables.

RESULTS

Longer step length and faster gait speed were related to faster processing speed and less intraindividual variability in the choice reaction test. Moreover, longer step length was also related to less fall-related concerns and less severe fall-related injuries, while faster gait speed was also related to female sex and poorer global cognition. Lower dual-task cost for gait speed was explained by the executive function inhibition and faster processing speed. Postural sway in quiet stance was not explained by cognitive functions.

CONCLUSIONS

Cognitive functions explained gait speed and step length during normal walking, as well as the decrease of gait speed while performing a concurrent cognitive task. The results suggest that different cognitive processes are important for different postural control aspects. Postural sway in quiet stance, step time and gait variability seem to depend more on physical and automatic processes rather than higher cognitive functions among physically active older people. The relationships between cognitive functions and postural control likely vary depending on the specific tasks and the characteristics of different populations.

A pilot study to identify factors associated with frailty within the World Trade Center general responder cohort

BACKGROUND

Given the significant exposures experienced by the World Trade Center (WTC) general responders, there is increasing interest in understanding the effect of these exposures on aging in this population. We aim to identify factors that may be associated with frailty, a clinical syndrome characterized by a decrease in one's reserve that has been linked to poor health outcomes.

METHODS

WTC general responders enrolled in the WTC Health Program aged 50 and older provided informed consent. Validated frailty assessments, the Frailty Phenotype (with the Johns Hopkins Frailty Assessment Calculator) along with the FRAIL scale, categorized nonfrail from prefrail/frail. Fall risk, functional status, and cognition were also assessed. WTC variables, including an identified WTC-certified condition, were utilized. The risk of frailty was estimated using log binomial regression analysis. A 95% confidence interval (CI) was used to estimate the prevalence ratio (PR).

RESULTS

One hundred and six participants were included; 38 (35.8%) were classified as pre-frail or frail. More of the pre-frail/frail group were obese (57.9% vs. 25%; p = 0.004) and had a WTC-certified condition (78.9% vs. 58.8%; p = 0.036). Obesity (PR = 2.43, 95% CI = 1.31, 4.53), a WTC-certified condition (PR = 1.77, 95% CI = 1.09, 2.89), and risk of falling (PR = 1.97, 95% CI = 1.01, 3.84) were independently associated with frailty.

CONCLUSIONS

Obesity and having a WTC-certified condition were found to be risk factors for frailty in our pilot study. Future work may focus on further identifying risk factors for frailty in the larger WTC general responder population.

Motivational Interviewing for Fall Prevention (MI-FP) pilot study: Older Adults' readiness to participate in fall prevention

Older adults' readiness to participate in fall prevention behaviors is largely unknown. We evaluated the feasibility of recruitment for a fall prevention intervention and participants' readiness to participate in fall prevention activities. Patients ≥ 65 years at high fall risk were recruited. Feasibility of recruitment was assessed by reaching the goal sample size (200), and recruitment rate (50%). Surveys assessed participants' readiness to participate in fall prevention activities (confidence to manage fall risks [0-10 scale; 10 most confident] and adherence to fall prevention recommendations). We recruited 200 patients (46.3% of eligible patients), and 185 completed surveys. Participants reported high confidence (range 7.48 to 8.23) in addressing their risks. Their adherence to clinician recommendations was mixed (36.4% to 90.5%). We nearly met our recruitment goals, and found that older adults are confident to address their fall risks, but do not consistently engage in fall prevention recommendations.

A systematic review and meta-analysis of the measurement properties of concerns-about-falling instruments in older people and people at increased risk of falls

BACKGROUND

The 16-item Falls Efficacy Scale International (FES-I) is widely used to assess concerns-about-falling. Variants include 7-item Short FES-I, 30-item Iconographical Falls Efficacy Scale (Icon FES) and 10-item short Icon FES. No comprehensive systematic review and meta-analysis has been conducted to synthesise evidence regarding the measurement properties of these tools.

OBJECTIVES

To conduct a systematic review and meta-analysis of the measurement properties of four FES-I variants.

METHODS

MEDLINE, Embase, CINAHL Plus, PsycINFO and Web of Science were searched systematically and articles were assessed for eligibility independently. The methodological quality of eligible studies was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. The quality of measurement properties was assessed using COSMIN criteria for good measurement properties. Where possible, meta-analysis was conducted; otherwise, narrative synthesis was performed. Overall certainty of evidence was rated using a modified Grading of Recommendations, Assessment, Development and Evaluation system approach.

RESULTS

The review included 58 studies investigating measurement properties of the four instruments. There was high-quality evidence to support internal consistency, reliability and construct validity of all instruments. Moderate- to high-certainty evidence suggests one-factor structure of FES-I with two underlying dimensions, one-factor structure of Short FES-I and two-factor structure of Icon FES. There was high-certainty evidence to support the responsiveness of FES-I, with further research needed for the other instruments.

CONCLUSION

There is evidence for excellent measurement properties of all four instruments. We recommend the use of these tools with healthy older people and people at a greater risk of falls due to conditions that might affect mobility and balance.

Evaluation of race as a predictor of fear of falling in Black older adults

OBJECTIVE

Determine whether race predicts fear of falling (FOF) in older adults with a history of previous fall(s) while controlling for mobility performance, activity of daily living (ADL) independence, age, gender, and education.

METHODS

We examined predictors of FOF among community-dwelling older adults using data from two longitudinal randomized controlled trials that implemented fall prevention programs for community-dwelling older adults.

RESULTS

Two hundred fifty-nine participants were included in the analysis; 145 reported low FOF, while 59 reported high FOF. After controlling for mobility performance, ADL independence, and sociodemographic factors, Black older adults were more likely to report FOF (OR = 2.17) compared to White older adults. Overall, older adults with lower mobility performance/functioning scores were more likely to have FOF (OR = 0.08).

CONCLUSIONS

Older adults (aged ≥65 years) who are at higher risk, based on a prior history of fall(s), are more susceptible to developing FOF, as evidenced by the older adults within this study, due to limited mobility performance and functioning.

CLINICAL IMPLICATIONS

Black older adults may be at greater risk of FOF than their White counterparts based on previous fall history and level of functional mobility. Incorporating measures of objective performance-based function along with measures of psychological factors are viable methods to identify and address FOF within Black older adult populations.

What Explains Successful or Unsuccessful Postural Adaptations to Repeated Surface Perturbations among Older Adults?

As we age there are natural physiological deteriorations that decrease the accuracy and flexibility of the postural control system, which increases the risk of falling. Studies have found that there are individual differences in the ability to learn to manage repeated postural threats. The aim of this study was to investigate which factors explain why some individuals are less proficient at adapting to recurrent postural perturbations. Thirty-five community dwelling older adults performed substantial sensory and motor testing and answered surveys regarding fall-related concerns and cognitive function. They were also subjected to three identical surface perturbations where both kinematics and electromyography was captured. Those that were able to adapt to the third perturbation were assigned to the group “Non-fallers” whereas those that fell during all perturbations were assigned to the group “Fallers”. The group designation dichotomized the sample in a hierarchical orthogonal projection of latent structures— the discriminant analysis model. We found that those who fell were older, had poorer physical performance, poorer strength and longer reaction times. The Fallers’ postural control strategies were more reliant on the stiffening strategy along with a more extended posture and they were less skillful at making appropriate feedforward adaptations prior to the third perturbation.

Fear of Falling Among Community-Dwelling Older Adults with Heart Disease: Findings from an International Mobility in Aging Study (IMIAS)

Background: Older adults with heart disease (HD) are more likely to report a higher prevalence of falls compared to those without HD. A knowledge gap currently exists regarding the factors associated with fear of falling (FOF) among older adults with HD. Therefore, this study aimed to estimate FOF and identify factors associated with FOF among older adults with HD. Methods: Data came from a secondary analysis of the International Mobility in Aging Study (IMIAS) baseline (2012) data. FOF was measured using the Falls Efficacy Scale-International (FES-I). Stepwise linear regression was used to identify factors associated with FOF. Results: A total of 429 participants identified themselves as having heart disease diagnosed by their physician (mean age 69.5 ± 2.9). Older adults with HD reported on average (25.6) higher FOF than those without HD. For older adults with HD, FES-I increased significantly by 1.3, 1.0, and 0.6 points, when the Short Physical Performance Battery, the Leganes Cognitive Test, and QOL total scores decreased by one point. FES-I also significantly increased by 3.2 when income was insufficient compared to sufficient or very sufficient income. Discussion: FOF is multifactorial, and our findings provide a base for developing future management rehabilitation intervention programs aimed at decreasing FOF among older adults with HD.

Balance confidence and physical activity participation of independently ambulatory youth with cerebral palsy: an exploration of youths' and parents' perspectives

AIM

Youth with cerebral palsy generally participate in less physical activity than typically developing peers. In adults with physical disabilities, balance confidence is a strong predictor of participation and community re-integration. However, balance confidence has not been studied in youth with cerebral palsy.

METHOD

Qualitative descriptive methodology with interviews of eight youth with cerebral palsy (9-17 years old, three girls) in Gross Motor Function Classification System Levels I-III, and eight parents (five mothers) of youth with cerebral palsy (9-17 years old, two girls) in Levels I-III.

RESULTS

Three themes arose: (1) youth in Gross Motor Function Classification System Levels I-II are more concerned about losing their balance during physical activities than those in Level III; (2) when balance is lost, embarrassment and frustration are more common than fear, especially for those in Levels I-II; and (3) social factors can create a favorable participation environment when balance confidence is low, especially for youth in Levels I-II.

CONCLUSION

Balance confidence may have greater influence on physical activity participation for youth in Gross Motor Function Classification System Levels I-II than those in Level III. Youth in Levels I-II may draw greater benefit from interventions targeting balance confidence when addressing physical activity goals.IMPLICATIONS FOR REHABILITATIONBalance confidence may have a greater influence on activity avoidance for youth with cerebral palsy in Gross Motor Function Classification System Levels I and II (who are independently ambulatory without walkers or cane(s)) than for those in Level II (who use walkers or cane(s) to ambulate).Youth who are independently ambulatory without walkers or cane(s) may benefit more from interventions directed at balance confidence (e.g., enactive mastery and verbal persuasion) to address their physical activity participation goals.For youth who are independently ambulatory without walkers or cane(s), addressing factors that could reduce the influence of balance confidence on physical activity participation, such as providing a positive and supportive social environment in which to participate, may be beneficial.

A Qualitative Study of Nursing Students' Experiences in Fall Prevention for Older Home Care Clients

The aim of this study was to describe the experiences of nursing students in fall prevention during clinical practice in the context of older home care clients. This was a qualitative focus group study of nursing students (n = 9) who had completed clinical practice in older clients' home care. The data were analysed using inductive content analysis. The nursing students described their experiences regarding falls and fall prevention in older clients' home care from two perspectives: evaluation of falls at older people's homes and fall prevention during home visits. Systematic evaluation of falls was based on physical examination and is the basis of fall prevention. However, evaluation of nutrition and adverse drug effects seemed to be ignored. In addition, fall prevention during home visits included concrete fall prevention in authentic client situations, confidential relationships with older clients, and evidence-based knowledge. From the perspective of fall prevention, there was a lack of comprehensive evaluation and understanding of the meaning of psychological factors, such as fear of falling. In order to be able to prevent falls in the older client population, students need more guidance regarding a comprehensive approach based on evaluation of falls. In addition, there is a need for continuous collaboration between education and home care services to develop educational approaches that interlink knowledge and skills in fall prevention.

Fear of Falling Assessment and Interventions in Community-Dwelling Older Adults: A Mixed Methods Case-Series

OBJECTIVES

(1) assess fear of falling (FOF) in community-dwelling older adults using subjective and objective measures and, (2) explore older adults' perceptions of FOF assessments and interventions.

METHODS

A mixed methods case-series was utilized. It consisted of quantitative data collection by objective measures including the BTrackS^TM Balance Test (BBT) and a dynamometer to assess physiological fall risk, and in-depth interviews from four older adults in Orlando, Florida. A single Fear of Falling Scale and Falls Efficacy Scale-International (FES-I) were used to assess FOF. To combine quantitative and qualitative data, a case-specific analysis was used and followed by a cross-case analysis to gain a more comprehensive understanding of FOF.

RESULTS

We found an incongruent fear of falling with physiological fall risk. Four themes emerged: (1) Fluctuating definitions of "fear" contribute to difficulty in assessments and interventions, (2) Fundamental assessments for fear of falling are missing, (3) Feedback from an objective measure is valuable, and (4) Family experiences with fear of falling drive personal interventions.

CONCLUSIONS

The integrated viewpoints from quantitative and qualitative data suggest a need for FOF assessment based on older adults' perceptive and physiological measures.

CLINICAL IMPLICATIONS

Healthcare providers should assess FOF using subjective and objective measures.

Factors included in adult fall risk assessment tools (FRATs): a systematic review

Falls often have severe financial and environmental consequences, not only for those who fall, but also for their families and society at large. Identifying fall risk in older adults can be of great use in preventing or reducing falls and fall risk, and preventative measures that are then introduced can help reduce the incidence and severity of falls in older adults. The overall aim of our systematic review was to provide an analysis of existing mechanisms and measures for evaluating fall risk in older adults. The 43 included FRATs produced a total of 493 FRAT items which, when linked to the ICF, resulted in a total of 952 ICF codes. The ICF domain with the most used codes was body function, with 381 of the 952 codes used (40%), followed by activities and participation with 273 codes (28%), body structure with 238 codes (25%) and, lastly, environmental and personal factors with only 60 codes (7%). This review highlights the fact that current FRATs focus on the body, neglecting environmental and personal factors and, to a lesser extent, activities and participation. This over-reliance on the body as the point of failure in fall risk assessment clearly highlights the need for gathering qualitative data, such as from focus group discussions with older adults, to capture the perspectives and views of the older adults themselves about the factors that increase their risk of falling and comparing these perspectives to the data gathered from published FRATs as described in this review.

Factors associated with the risk for falls in PACE participants

OBJECTIVE

The purpose was to determine the relationship between frailty, fear of falling, and depression with falls risk in vulnerable community-dwelling older adults.

METHODS

A cross-sectional correlational design and chart review were completed. Nursing home eligible older adults ≥55 who live in the community were surveyed on frailty, fear of falling, depression, and the risk for falls. Pearson's correlation, multiple regression and hierarchical regression were used to analyze the data.

RESULTS

Increased frailty, fear of falling, and depression were significantly associated with an increased risk for falls. Frailty and fear of falling were significant predictors of the risk for falls while depression did not contribute to the regression model. When controlling for sociodemographics, frailty, fear of falling, and incontinence were significant predictors for the risk for falls.

DISCUSSION

The results of this study will assist in assessment and interventions to decrease the risk for falls in high risk older adults.

Locomotive function and quality of life among older people in Liaoning, China: Falls efficacy as mediator or moderator?

OBJECTIVES

This study aimed to examine the role of falls efficacy in the relationship between the locomotive function and quality of life.

METHODS

From March to May in 2016, we conducted a cross-sectional survey among 830 community residents aged ≥60 years from Jinzhou,China.GLFS-25 (25-question Geriatric Locomotive Function Scale), FES-I(International edition of Falls Efficacy Scale),and SF-12 (12-item Short Form Health Survey) were used to estimate locomotive function, falls efficacy and quality of life, respectively. The higher score of GLFS-25, the worse the locomotive function.

RESULTS

Median age was 68.69 years (ranges 60-88). Locomotive function, falls efficacy and quality of life all presented a linear relationship within each other, locomotive function score was negatively correlated with falls efficacy score (-0.461, P < 0.01). locomotive function score was negatively correlated with quality of life score (-0.523, P < 0.01).Falls efficacy score was positively correlated with quality of life score (0.415, P < 0.01).Falls efficacy exerted both a mediating and moderating role between locomotive function and quality of life, and the mediation effect accounted for 45.5% of the total effect.

CONCLUSIONS

Poorer locomotive function was associated with poorer quality of life, and greater falls efficacy was associated with better quality of life. In addition, falls efficacy was demonstrated to be both a mediator and moderator variable in the linkage between locomotive function and quality of life. Aged care professional practitioners and our policy makers should strengthen the awareness of the psychological role of the elderly falls efficacy.
