Relationship among fear of falling, physical performance, and physical characteristics of the rural elderly

Are history of falls and fear of falling associated with mobility in community-dwelling older adults?

Evidence has suggested that a history of falls and fear of falling (FOF) are associated with reduced mobility among older adults. Although many studies have explored the association between the history of falls and FOF in the context of decreased mobility, most have had small sample sizes, limiting the generalizability of the results. Therefore, this study sought to contribute to the body of knowledge around these constructs to further support the previous findings. To investigate the association between a history of falls and FOF with low mobility in community-dwelling older adults. This cross-sectional study included 308 older adults (69.9 ± 7.1 years, 57.8% female). The Timed Up and Go (TUG) test was used to classify mobility limitations in participants and the Falls Efficacy Scale-International - Brazil was used to quantify FOF. Participants were also asked if they had fallen in the previous 12 months. Multivariable logistic regression was used. The prevalence rates of a history of falls and FOF were 32.7 and 48.4%, respectively. Older adults with a history of falls and FOF had 2.20 (95%CI: 1.20; 4.02) and 3.80 (95%CI: 1.90; 7.58) greater odds of presenting low mobility than older adults without these health problems, respectively. History of falls and FOF are associated with higher odds of low mobility in community-dwelling older adults. Therefore, it is of the utmost importance to introduce public health programs aimed at preventing falls in older adults to reduce possible adverse health outcomes, including low mobility.

The relationship between fear of falling and functional ability following a multi-component fall prevention program: an analysis of clinical data

OBJECTIVES

The first objective was to evaluate clinical data from a multi-component fall prevention program. The second objective was to explore the relationship between physical function and fear of falling (FoF).

METHODS

Adults (N = 287, mean age = 76 years) who participated in the Building Balance Program between 2011-2020 were assessed with five physical function measures and two FoF measures. Repeated measures ANOVA controlling for age and sex were performed to assess change from baseline. Linear regressions were conducted to evaluate how physical function explained variations in FoF.

RESULTS

There were significant improvements between pre and post-program Berg Balance Scale (BBS) scores (p < .001), Timed-Up and Go (TUG) times (p < .001), 30 second Chair-Stand (30 CST repetitions) (p < .001), Functional Reach (FR) distance (p < .001), gait speed (p < .001), single item-FoF score (p < .001), and short Falls Efficacy Scale-International (FES-I score) (p < .001). After controlling for sex on all regression analyses, age, and pre-program gait speed explained variations in pre-program short FES-I scores (Adjusted R2 = 0.19). Age, pre-program BBS and 30 CST repetitions explained variations in pre-program level of FoF (Adjusted R2 = 0.25). Variations in post-program short FES-I scores (Adjusted R2 = 0.17) were explained by age, post-program TUG times and FR distance after controlling for age and sex. Robust regressions indicated variations in post-program level of FoF explained by age, post-program TUG and FR distance with a two-way interaction between age and FR.

CONCLUSION

A multi-component fall prevention program improved physical function and decreased FoF. A small association between physical function and FoF similar between pre- and post-program conditions was identified.

The global prevalence of and risk factors for fear of falling among older adults: a systematic review and meta-analysis

BACKGROUND

As a common psychological problem among older adults, fear of falling was found to have a wide range prevalence in different studies. However, the global prevalence of it was unknown and a lack of the large sample confirmed its risk factors.

OBJECTIVES

To report the global prevalence of fear of falling and to explore its risk factors among older adults for further developing precise interventions to systematically manage FOF.

DESIGN

A systematic review and meta-analysis was conducted by PRISMA guidelines.

METHODS

Searches were conducted in PubMed, Web of Science, EMBASE, the Cochrane Library and the manual search in August 20, 2022, updated to September 2, 2023. Observational studies published in English were included and two researchers independently screened and extracted the data. Fixed or random effects mode was used to estimate the pooled prevalence of and risk factors for fear of falling. Heterogeneity resources were analyzed by subgroup and sensitivity analysis. Publication bias was assessed through funnel plots, Egger's test and Begg's test.

RESULTS

A total of the 153 studies with 200,033 participants from 38 countries worldwide were identified. The global prevalence of fear of falling was 49.60%, ranging from 6.96-90.34%. Subgroup analysis found the estimates pooled prevalence of it was higher in developing countries (53.40%) than in developed countries (46.7%), and higher in patients (52.20%) than in community residents (48.40%). In addition, twenty-eight risk factors were found a significant associations with fear of falling, mainly including demographic characteristics, physical function, chronic diseases and mental problems.

CONCLUSION

The global prevalence of FOF was high, especially in developing countries and in patients. Demographic characteristics, Physical function, chronic diseases and mental problems were a significant association with FOF. Policy-makers, health care providers and government officials should comprehensively evaluate these risk factors and formulate precise intervention measures to reduce FOF.

TRIAL REGISTRATION

The study was registered in the International Database of Prospectively Registered Systematic Reviews (PROSPERO): CRD42022358031.

Fear of Falling in Older Adults Living in a Community-Dwelling Facility: Prevalence and Its Impact on Activity Behavior and Physical Function

This study examined the prevalence and the impact of fear of falling (FOF) on physical activity (PA), sedentary behavior (PA), and physical function in older adults living in a continuing care retirement community (CCRC). Ninety-three older adults were included and self-reported assessed on PA and SB. Further, participants' physical function was assessed using a collection of measures of valid objective tests. Independent t test was used to compare the dependent variables between FOF groups, and analysis of covariance (ANCOVA) was used to control for assistive device usage. FOF was prevalent in 47.3% of the sample and PA and SB did not differ between FOF groups (p > .05). ANCOVA revealed that performance on several physical function tests remained significantly better (p < .05) for the no FOF group compared to the yes group. Our findings demonstrated similar levels of PA and SB between FOF groups, but worse physical function for older adults reporting FOF.

Spinopelvic Alignment as a Risk Factor for Poor Balance Function in Low Back Pain Patients

STUDY DESIGN

Retrospective, observational study.

OBJECTIVES

This study aimed to examine the association between spinopelvic parameters and balance function in low back pain (LBP).

METHODS

Among patients in the rehabilitation medicine department, the data of 182 patients (mean age, 47.8 years; M/F = 64/118) was obtained retrospectively. Spinopelvic parameters were measured through a whole-body low-dose biplanar radiography using the EOS imaging system, and balance function was evaluated by the center of pressure (COP) movement using the Zebris treadmill system. Pearson correlations were used to determine the relationship between radiographic and balance function. Stepwise multiple linear regression analyses were conducted with the balance function as a dependent variable and age and spinopelvic parameters as independent variables.

RESULTS

Increased age, knee flexion (KF), pelvic tilt (PT), C7-central sacral line (C7-CSL) and C7 sagittal vertical axis (SVA), and decreased spino-sacral angle (SSA) were associated with both poor static and dynamic balance. Moreover, increased Cobb's angle and decreased thoracic kyphosis (TK) and lumbar lordosis (LL) was associated with poor static balance. Increased pelvic incidence (PI) was related to poor dynamic balance. Increased age, Cobb's angle, SVA, and decreased TK were risk factors for poor static balance. For dynamic balance, increased age, C7-CSL, and PT were risk factors for poor sagittal balance, whereas increased CAM-plumb line and PT were risk factors for poor coronal balance.

CONCLUSIONS

Balance function was associated with spinopelvic parameters in patients with LBP. Increased SVA, followed by increased PT, was the strongest independent factor associated with poor static and dynamic balance.

Adding Weight Shift Training to Weight Reduction Decreases the Risk of Falling in Obese Women: A Prospective Randomized Controlled Trial

OBJECTIVE

The aim of this study was to examine the effect of adding weight shift training to a weight loss program on the risk of falling, fear of falling, overall stability, anteroposterior stability, mediolateral stability, and isometric knee torque in young obese women.

DESIGN

A single-blinded, randomized controlled study was performed. Sixty women, 18 to 46 yrs old, were randomly assigned either to the study or the control group. The participants in the study group were given weight-shifting training plus a weight reduction program; the control group received only a weight-reduction program. The interventions were performed for 12 wks. At baseline and after 12 wks of training, the risk of falling, fear of falling, overall stability, anteroposterior stability, mediolateral stability, and isometric knee torque were all examined.

RESULTS

There were statistically significant differences in risk of falling, fear of falling, isometric knee torque, and overall, anteroposterior, and mediolateral stability indices, in favor of the study group, after 3 mos of training ( P < 0.001).

CONCLUSIONS

Weight shift training combined with weight reduction was more beneficial than weight reduction alone in decreasing the risk of falling and fear of falling and improving isometric knee torque and overall, anteroposterior, and mediolateral stability indices. It could be used for treating balance problems and weakness around the knee joint in obese women.

Bidirectional relationship between fear of falling and frailty among community-dwelling older adults: A longitudinal study

This study aims to examine the bidirectional association between fear of falling (FOF) and frailty among community-dwelling older adults. Longitudinal analyses were conducted over a representative sample of 5,829 community-dwelling individuals ≥65 years from the National Health and Aging Trends Study. FOF was ascertained by asking participants whether they worried about falling and if this worry ever limited their activities. Frailty status was assessed based on frailty phenotype. At baseline, 71.4% of participants reported no FOF, 16.7% reported FOF without fear-related activity restriction (FAR), and 11.9% reported FOF with FAR. The proportion of robust, pre-frail and frail respondents at baseline was 36.1%, 48.7% and 15.2%, respectively. Multinomial logistic regression models indicated FOF with and without FAR predicted pre-frailty and frailty. Pre-frailty predicted FOF with and without FAR, while frailty only predicted FOF with FAR. Tailored intervention strategies are needed for preventing adverse outcomes of FOF and frailty among the older population.

Accounting for Diversity in Robot Design, Testbeds, and Safety Standardization

Science has started highlighting the importance of integrating diversity considerations in medicine and healthcare. However, there is little research into how these considerations apply, affect, and should be integrated into concrete healthcare innovations such as rehabilitation robotics. Robot policy ecosystems are also oblivious to the vast landscape of gender identity understanding, often ignoring these considerations and failing to guide developers in integrating them to ensure they meet user needs. While this ignorance may be for the traditional heteronormative configuration of the medical, technical, and legal world, the ending result is the failure of roboticists to consider them in robot development. However, missing diversity, equity, and inclusion considerations can result in robotic systems that can compromise user safety, be discriminatory, and not respect their fundamental rights. This paper explores the impact of overlooking gender and sex considerations in robot design on users. We focus on the safety standard for personal care robots ISO 13482:2014 and zoom in on lower-limb exoskeletons. Our findings signal that ISO 13482:2014 has significant gaps concerning intersectional aspects like sex, gender, age, or health conditions and, because of that, developers are creating robot systems that, despite adherence to the standard, can still cause harm to users. In short, our observations show that robotic exoskeletons operate intimately with users’ bodies, thus exemplifying how gender and medical conditions might introduce dissimilarities in human–robot interaction that, as long as they remain ignored in regulations, may compromise user safety. We conclude the article by putting forward particular recommendations to update ISO 13482:2014 to reflect better the broad diversity of users of personal care robots.

Effectiveness of the non-face-to-face comprehensive elderly care application "smart silver care" for community-dwelling elderly: A randomized controlled trial

Background

Quality of life for the elderly has become an important issue, and services aimed at improving it have typically been provided face-to-face. However, coronavirus disease 2019 has limited the use of face-to-face services, and the need to convert such systems to online interfaces has emerged.

Objective

This study evaluates the effectiveness of a non-face-to-face comprehensive elderly care application called "Smart Silver Care."

Methods

This study was designed as a randomized controlled trial. Sixty community-dwelling elderly individuals were randomly assigned to experimental and control groups in a 1:1 ratio. The participants participated in the "Smart Silver Care" intervention using a tablet and smartwatch based on the programs we provided. The participants performed five tasks, five days a week, consisting of physical, emotional, and cognitive programs. Participants could communicate with the researchers in real-time from their homes, and the researchers could remotely supervise their performance.

Results

We found positive effects on the relevant scales testing fall risk (Activities-Specific Balance Confidence [ABC] Scale, p = 0.028; Timed Up and Go [TUG] test, p = 0.001). However, there was no time × group interaction between the experimental and control groups on the relevant scales for depression and quality of life (Short Form-Geriatric Depression Scale [SGDS]-K: p = 0.225; EuroQol five-dimension five-level [EQ-5D-5L], p = 0.172). While the SGDS-K and EQ-5D-5L did not show statistical significance, we found improvement trends in the experimental group.

Conclusions

The findings of this study show that Smart Silver Care significantly improved the participants' TUG and ABC scores in community-dwelling elderly, and a qualitative evaluation confirmed that it could be conveniently used by the elderly. Thus, Smart Silver Care offers a feasible intervention to improve the quality of life of the elderly, including physical aspects.

The Prevalence of Sarcopenia among Hunan Province Community-Dwelling Adults Aged 60 Years and Older and Its Relationship with Lifestyle: Diagnostic Criteria from the Asian Working Group for Sarcopenia 2019 Update

Background and Objectives: This study aims to detect the prevalence of sarcopenia in community-dwelling older adults in Hunan Province, discuss factors related to lifestyle, and provide a reliable basis for the prevention and treatment of sarcopenia. Materials and Methods: In this study, a total of 1040 community-dwelling adults ≥ 60 years were examined for sarcopenia using a cluster stratified random sampling method, which was defined using the diagnostic criteria recommended by the Asian Working Group for Sarcopenia (AWGS) from September 2019 to March 2020. Multivariate logistic regression analysis was applied to determine the correlation between sarcopenia and smoking, drinking, nutritional status, physical activity, and sleep quality. Results: A total of 27.1% of the older adults were diagnosed with sarcopenia, with rates of 26.2% in men and 25.2% in women. Multiple logistic regression showed that advanced age (OR = 2.480, 95% CI: 1.730, 3.553), the risk of malnutrition (OR = 2.085, 95% CI: 1.440, 3.019), and malnutrition (OR = 1.212, 95% CI: 0.304, 4.834) were risk factors for sarcopenia. No falls in the previous year (OR = 0.616, 95% CI: 1.885, 1.209), normal weight (OR = 0.228, 95% CI: 0.109, 0.475), overweight (OR = 0.030, 95% CI: 0.013, 0.069), moderate physical activity (OR = 0.593, 95% CI: 0.377, 0.933), or high physical activity (OR = 0.417, 95% CI: 0.230, 0.755) were identified as protective factors for sarcopenia. Conclusions: The prevalence of sarcopenia was high among older adults in the community in Hunan Province. In addition, we found that lifestyle is an important factor in sarcopenia.

The Impact of "Fear of Falling" on Physical Performance, Balance, and Ambulation in Duchenne Muscular Dystrophy

OBJECTIVE

The aim of this study was to investigate falls and the fear of falling (FOF) in children with Duchenne muscular dystrophy (DMD) and to determine the relationships between the FOF and physical performance, balance, and ambulation.

METHODS

Thirty-eight ambulatory children with DMD were included in the study. The functional level, falling history, FOF, physical performance, balance, and ambulation were assessed by using Brooke Lower Extremity Functional Classification, History of Falls Questionnaire, Pediatric Fear of Falling Questionnaire (Ped-FOF), timed performance tests, Timed "Up and Go" (TUG) test, and North Star Ambulatory Assessment (NSAA), respectively.

RESULTS

Of the 38 children (mean age: 9.00 ± 2.03 years) 97.4% had a history of serious fall last year and 62.2% were injured due to this fall. The Ped-FOF score was 13.79 ± 7.20. Weak to moderate relations were determined between Ped-FOF and functional level (r = 0.33), frequency of falls (r = 0.41), duration of climbing 4-steps (r = 0.38), TUG (r = 0.36), and NSAA (r = -0.32) (p < 0.05).

CONCLUSION

Ambulatory children with better performance scores had lower levels of FOF despite their history of serious falls and injuries. FOF tends to increase as the symptoms of the disease progresses. Investigating the history of falls and FOF from the earliest period will guide to take precautions and make necessary interventions on time in treatment programs.

Impaired ankle inversion proprioception during walking is associated with fear of falling in older adults

Background

Ankle proprioception plays a critical role in lower limb movement control. However, the relationship between ankle proprioception and fear of falling (FOF) in older people is still unclear.

Objective

(1) This study aims to develop a new device for measuring ankle inversion proprioceptive discrimination sensitivity during walking, i.e., the Ankle Inversion Discrimination Apparatus–Walking (AIDAW), and assess the test–retest reliability of the AIDAW in both young and older adults; (2) to evaluate the discriminant validity of the measure by comparing ankle proprioception during walking between the two groups; and (3) to explore convergent validity by determining to what extent the AIDAW proprioceptive scores correlate with Fall Efficacy Scale-International (FES-I) scores.

Materials and methods

The AIDAW was purpose-built to test ankle inversion proprioceptive discrimination sensitivity during walking. The area under the receiver operating curve (AUC) was calculated as the proprioceptive discrimination score. In total, 54 adults volunteered. Test–retest reliability was evaluated in 12 young and 12 older adults, and another 15 young and 15 older adults completed the comparison study. FOF was assessed by using the FES-I.

Results

The test–retest reliability intraclass correlation coefficient ICC _(3,1) value for the whole group was 0.76 (95% CI: 0.52–0.89). The ICC values of the young and older groups were 0.81 (95% CI: 0.46–0.94) and 0.71 (95% CI: 0.26–0.91), respectively. The Minimal Detectable Change with 90% confidence (MDC₉₀) values for the young and older groups were 0.03 and 0.11, respectively. There was a significant difference between the AIDAW proprioceptive sensitivity scores for the young and older groups (0.78 ± 0.04 vs. 0.72 ± 0.08, F = 5.06, p = 0.033). Spearman’s correlation analysis showed that the FES-I scores were significantly and negatively correlated with the AIDAW scores (rho = −0.61, p = 0.015), with higher FOF associated with worse ankle proprioception.

Conclusion

The AIDAW is a reliable and valid device for measuring ankle proprioception during walking in both young and older adults. Ankle inversion proprioceptive discrimination sensitivity during walking was found to be impaired in the elderly compared to young adults. This impairment was found to be strongly associated with FOF, suggesting that assessment and intervention for ankle proprioception in this population are needed to reduce the risk of falls.

Cognitive, psychological and social factors associated with older adults' mobility: a scoping review of self-report and performance-based measures

Although many factors have been associated with mobility among older adults, there is paucity of research that explores the complexity of factors that influence mobility. This review aims to synthesise the available evidence for factors comprising the cognitive, psychological, and social mobility determinants and their associations with mobility self-reported and performance-based outcomes in older adults (60 years). We followed Arksey and O'Malley's five stages of a scoping review and searched PubMed, EMBASE, PsychINFO, Web of Science, AgeLine, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature and Sociological Abstract databases. Reviewers in pairs independently conducted title, abstract, full-text screening and data extraction. We reported associations by analyses rather than articles because articles reported multiple associations for factors and several mobility outcomes. Associations were categorised as significantly positive, negative, or not significant. We included 183 peer-reviewed articles published in 27 countries, most of which were cross-sectional studies and conducted among community-dwelling older adults. The 183 articles reported 630 analyses, of which 381 (60.5%) were significantly associated with mobility outcomes in the expected direction. For example, older adults with higher cognitive functioning such as better executive functioning had better mobility outcomes (e.g., faster gait speed), and those with poor psychological outcomes, such as depressive symptoms, or social outcomes such as reduced social network, had poorer mobility outcomes (e.g., slower gait speed) compared to their counterparts. Studies exploring the association between cognitive factors, personality (a psychological factor) and self-reported mobility outcomes (e.g., walking for transportation or driving), and social factors and performance-based mobility outcomes in older adults are limited. Understanding the additive relationships between cognitive, psychological, and social factors highlights the complexity of older adults' mobility across different forms of mobility, including independence, use of assistive devices, transportation, and driving.

Static Balance and Chair-Rise Performance in Neurogeriatric Patients: Promising Short Physical Performance Battery-Derived Predictors of Fear of Falling

Background

Fear of falling (FOF) negatively affects health-related quality of life and is common in neurogeriatric patients, however, related parameters are not well understood. This study investigated the relationship between FOF, physical performance (as assessed with the Short Physical Performance Battery and its subscores) and other aspects of sarcopenia in a sample of hospitalized neurogeriatric patients.

Methods

In 124 neurogeriatric patients, FOF was assessed with the Falls Efficacy Scale International (FES-I). Physical performance was measured using the Short Physical Performance Battery (SPPB) including walking duration, balance and five times sit-to-stand task (5xSST) subscores. Appendicular skeletal muscle mass (ASMM) was estimated with the cross-validated Sergi equation using Bioelectrical impedance analysis measures. The Depression im Alter-Skala (DIA-S) was used to assess depressive symptoms. Multiple regression models with FES-I score as outcome variable were computed using backward selection with AICc as selection criterion, including: (i) SPPB total score, ASMM/height2, grip strength, age, gender, positive fall history, number of medications, use of a walking aid, DIA-S score and Montreal Cognitive Assessment (MoCA) score; and (ii) SPPB subscores, ASMM/height2, grip strength, age, gender, positive fall history, number of medications, DIA-S score and MoCA score, once with and once without including use of a walking aid as independent variable.

Results

Lower SPPB total score, as well as lower SPPB balance and 5xSST subscores were associated with higher FES-I scores, but SPPB walking duration subscore was not. Moreover, DIA-S, number of medications and use of a walking aid were significantly associated with FOF.

Conclusion

Our preliminary results suggest that -if confirmed by subsequent studies- it may be worthwhile to screen patients with low SPPB balance and 5xSST subscores for FOF, and to treat especially these mobility deficits in neurogeriatric patients with FOF. Moreover, training neurogeriatric patients to use their walking aids correctly, critical evaluation of medication and treating depressive symptoms may further help reduce FOF in this highly vulnerable cohort.

Association between Fear of Falling and Seven Performance-Based Physical Function Measures in Older Adults: A Cross-Sectional Study

Fear of falling (FOF), a common phenomenon among older adults, may result in adverse health consequences. The strength of the association between FOF and physical function among older adults has not been well compared in previous studies. Therefore, a cross-sectional study was performed on 105 older adults to determine and compare the strength of the association between FOF and seven common physical function measures. After controlling for age, logistic regression models were fitted for each physical function measure. According to odds ratios, the Berg Balance Scale (BBS), Short Physical Performance Battery, gait speed, and Timed Up & Go Test were associated with the identification of FOF. Based on a c-statistic value of 0.76, the BBS, a common and quick assessment of functional balance tasks, was found to be able to distinguish between fearful and non-fearful older adults. Interventions targeted to improve lower-extremity physical functions, especially functional balance ability, may help prevent or delay the adverse consequences of FOF.

Relationships between the Perception of Footwear Comfort and the Fear of Falls in People at the Early Period of Old Age

Objective: The present study aimed to analyze the relationships between the perceptions of footwear comfort with fear of falls in younger-old women and men. Participants: the population sample involved 100 free-living community dwellers aged 65−74. Design: the Falls Efficacy Scale-International and a visual analogue scale to assess perception of footwear comfort were used as research tools. Results: there were statistically significant differences in the FES-I results in people who suffered a fall in the last year compared to those who did not experience a fall (p < 0.001), as well as in the subjective assessment of mediolateral control in people who have suffered and have not suffered a fall in the last year (p = 0.033). In women, statistically significant relationships were found in the subjective assessment of shoe comfort in terms of arch height (p = 0.025) and material properties of the footwear (p = 0.036) with the results of FES-I. Conclusions: People who have fallen show a higher level of fear of falling. The assessment of footwear comfort in terms of mediolateral control was lower in the younger-old who had experienced a fall in the last year. In women, a worse assessment of arch height and material properties of the footwear is accompanied by greater fear of falling.

The angiotensin-converting enzyme gene insertion/deletion polymorphism interacts with fear of falling in relation to stepping speed in community-dwelling older adults

BACKGROUND

Despite the association of genetic factors with falls, balance, and lower extremity functioning, interaction of the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with fear of falling (FOF) in relation to stepping performance has, to the best of our knowledge, not been investigated in older adults.

OBJECTIVE

The purpose of this study was to examine the interaction effects of the ACE I/D polymorphism with FOF in relation to stepping performance in older adults.

METHODS

Eighty-eight community-dwelling adults 60 years or older participated in a cross-sectional observational study. Participants completed tests of rapid and distance stepping, and self-reported FOF (yes/no). Participants provided saliva for ACE genotyping. General linear models evaluated ACE genotype × FOF interaction effects in relation to stepping performance. The α level was set at 0.05.

RESULTS

The ACE I/D polymorphism exhibited significant interaction effects (p for interactions 0.002 ≤ p ≤ .04) with FOF in relation to stepping speed. Relationships between FOF and stepping speed varied among ACE genotypes. The insertion/insertion (II) genotype was significantly associated (p = .01) with slow stepping in individuals with, but not without FOF (p > .05).

CONCLUSION

Variation in relationships between FOF and stepping speed among ACE genotypes suggests a role for the ACE I/D polymorphism in modifying relationships between FOF and stepping speed in older adults. The association of the ACE II genotype with slow stepping performance in individuals with, but not without FOF, suggests that older adults with the ACE II genotype and FOF may be at increased risk for poor stepping performance and associated functional declines.

The Effect of Convergence Gamification Training in Community-Dwelling Older People: A Multicenter, Randomized Controlled Trial

OBJECTIVES

It is necessary to improve the health of older adults through exercise, but there is no concrete way to implement it or an environment in which they can exercise continuously. Our objective was to confirm the safety and efficacy of information technology (IT) convergence gamification exercise equipment for older adults. We tried to demonstrate equivalence to conventional exercise by comparing the functional improvement.

DESIGN

Randomized controlled trial, with 8-week-long IT convergence exercises 3 times a week vs conventional exercise.

SETTING AND PARTICIPANTS

40 community-dwelling participants aged 60-85 years.

METHOD

Participants were randomly divided into a conventional exercise group (group 1) and an IT convergence exercise group (group 2). Both groups were trained for 8 weeks, and functional assessment was performed before training (pre-evaluation), after training, and after 4 weeks of rest.

RESULTS

There were functional improvements in both groups. A comparison of the differences in the functional assessment between pre-evaluation and after 8 weeks of training yielded the following results. In group 1, the mean Five Times Sit to Stand Test-30 seconds was scored as 3.60 ± 2.56 (P < .015); Five Times Sit to Stand Test-5 times, -1.75 ± 2.04 s (P < .015); Berg Balance Scale, 1.05 ± 1.39 (P < .015); Timed Up-and-Go test, -0.64 ± 0.64 s (P < .015); and 10-m Walking Test, -0.35 ± 0.47 s (P < .015). And in group 2, the mean Five Times Sit to Stand Test-30 seconds (s) was scored as 3.70 ± 2.62 (P < .015), Five Times Sit to Stand Test-5 times, -1.65 ± 1.59 s (P < .015); Berg Balance Scale, 1.05 ± 1.00 (P < .015); Timed Up-and-Go test, -0.93 ± 0.68 s (P < .015); 10-m Walking Test, -0.41 ± 0.489 s (P < .015); Chair Sit and Reach test, 2.23 ± 3.19 cm (P < .015); and Korean version of the Falls Efficacy Scale-International, -1.05 ± 1.43 (P < .015).

CONCLUSION AND IMPLICATIONS

The results of this study suggest that the IT convergence gamification exercise equipment such as balpro110 has exercise effects similar to conventional exercise and also has advantages as an alternative to exercise for older adults in the next generation.

Prevalence of Fear of Falling and Its Association With Physical Function and Fall History Among Senior Citizens Living in Rural Areas of China

Background: Fear of falling (FOF) is as significant as a fall, leading to limited physical activity and poor quality of life among senior citizens. This study aimed to investigate the prevalence of FOF and its association with physical function and fall history among the senior citizens (≥75 years old) living in rural areas of China. Methods: This was a cross-sectional study conducted in eastern China from June to October 2019. All elderly participants were recruited during their attendance for the free health examinations in villages and towns organized by the local healthcare authorities. Data on sociodemographics, fall history, FOF conditions, self-reported comorbidity and regular medications were collected by face-to-face interview, and the physical function status was evaluated through a field test. Univariate and multivariate analyses were performed to compare the differences in physical function and fall history of senior citizens with/without FOF. Results: A total of 753 senior citizens (mean age = 79.04) participated in this study. Of these, 63.5% were aged 75-80. FOF was reported in 22.8% of the participants, while 18.5% had a fall in the past year. Among the senior citizens with and without a fall history, the prevalences of FOF were 38.8 and 19.2%, respectively. On multivariate analyses, FOF was independently associated with the Time Up and Go Test (TUG) duration (OR = 1.080; 95% CI: 1.034-1.128), 4-Stage Balance Test score (OR = 0.746; 95% CI: 0.597-0.931), fall history (OR = 2.633; 95% CI: 1.742-3.980), cerebral apoplexy (OR = 2.478; 95% CI: 1.276-4.813) and comorbidities (≥2) (OR = 1.637; 95% CI: 1.066-2.514), while the correlation between FOF and the 30-s chair stand test was only statistically significant in univariate analysis (Z = -3.528, p < 0.001). Conclusion: High prevalence of FOF is observed among the senior citizens living in rural areas of China. FOF is strongly correlated with physical function performance and fall history. Therefore, the implementation of targeted FOF prevention measures is key to improve the physical activity of the senior citizens, which would ultimately lead to fall prevention and improved quality of life.

Physical Fitness among Community-Dwelling Older Women with and without Risk of Falling-The Taipei Study, Taiwan

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.

The Effects of Exercise Interventions on Balance Capacity in Patients with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

The effect of exercise intervention on balance capacity among type 2 diabetes mellitus (T2DM) patients has not been evaluated. The objective of this systematic review and meta-analysis is to investigate the effect of exercise intervention on balance capacity among T2DM patients compared to the control group (usual care, waitlist, no-treatment, education). We conducted a comprehensive literature search through PubMed, EMBASE, Physiotherapy Evidence Database (PEDro), Cochrane library, Web of Science (WOS) from inception to August 2020. The literature language was limited to English. Randomized controlled trials (RCTs) or quasi-experimental (Q-E) trials that examined the effect of exercise intervention on balance capacity among T2DM patients were included. We used the standard methods of meta-analysis to evaluate the outcomes of exercise intervention for balance capacity of T2DM patients. A total of 14 trials (11 RCTs and 3 Q-E trials) involving 883 participants were eligible. The meta-analysis of some studies demonstrated that exercise intervention could significantly improve Berg Balance Scale (BBS) (MD = 2.56; 95%CI [0.35, 4.77]; P = .02), SLST (Single Leg Stance Test) under the eyes-open (EO) condition (MD = 3.63; 95%CI [1.79, 5.47]; P = .0001) and eyes-close (EC) condition (MD = 0.41; 95%CI [0.10, 0.72]; P = .01) compared to control group. There was no significant difference in Time Up and Go Test (TUGT) (MD = -0.75; 95%CI [-1.69, 0.19]; P = .12) and fall efficacy (SMD = -0.44; 95%CI [-0.86, -0.01]; P = .05). Narrative review of some studies indicated that exercise intervention could improve postural stability measured by Sensory Organization Test (SOT) and Center of Pressure (COP) variables, etc. This systematic review and meta-analysis summarized that exercise intervention could improve balance capacity in T2DM patients. However, further studies with high quality are required to evaluate its effect.

Fall-related measures in elderly individuals and Parkinson's disease subjects

Falls pose a serious problem in elderly and clinical populations. Most often, they lead to a loss of mobility and independence. They might also be an indirect cause of death. The aim of this study was to determine an objective predictor of the fear of falling and falls in elderly subjects (ESs) and Parkinson's disease (PD) subjects. Thirty-two ESs were examined in this study, of whom sixteen were diagnosed with PD. The testing procedures comprised force plate measurements (limit of stability test-LOS test) and clinical tests (Berg Balance Scale, Functional Reach Test, Timed Up and Go test, Tinetti test). The Falls Efficacy Scale International (FES-I) was used to evaluate the fear of falling. The range of the maximum forward lean was normalized to the length from the ankle joint to the head of the first metatarsal bone and was named the functional forward stability indicator (FFSI). The FFSI, derived from the LOS test, allowed us to demonstrate the real deficit in functional stability and individual safety margins. Moreover, the FFSI was highly correlated with the FES-I score and almost all clinical test results in elderly subjects (r>0,6; p<0.05). In PD subjects, the FFSI was poorly correlated with the fear of falling, the BBS score and the FR distance; however, a high correlation with the Tinetii test (r>0,6, p<0.05) was noted. The PD subjects presented a different balance strategy when close to their stability limits, which was also reflected in the lower values of sample entropy (t = (-2.40); p<0.05; d = 0.87). The FFSI might be a good predictor of the fear of falling in the group of elderly people. Additionally, the FFSI allows us to show real balance deficits both in PD subjects and in their healthy peers without the need for a reference group and norms. In conclusion, it is postulated that the popular clinical assessments of postural balance in PD subjects should be accompanied by reliable posturography measurements.

Modified Timed Up and Go Test for Tendency to Fall and Balance Assessment in Elderly Patients With Gait Instability

Objective: To compare the results from the modified Timed Up and Go Test (TUG) with posturographic variables, the subjective perception of disability due to gait instability, and the number of falls in a sample of the elderly population with imbalance, to confirm that the TUG Test is a useful clinical instrument to assess the tendency to fall in individuals of this age group.

Materials and Methods: Cross-sectional study conducted in a tertiary university hospital, in 174 people aged 65 years or older with gait instability. Modified TUG Test was performed; time, step count and the need for support during the test were the analyzed variables. They were compared with the number of falls, Computerized Dynamic Posturography scores, and questionnaires scores (Dizziness Handicap Inventory and a shortened version of the Falls Efficacy Scale-International).

Results: The average time to complete the TUG Test was 21.24 ± 8.18 s, and the average step count was 27.36 ± 7.93. One hundred two patients (58.6%) required no support to complete the test, whereas the other 72 (41.4%) used supports. The time taken to complete the Test was significantly related with having or not having fallen in the previous year, with the scores of the questionnaires, and with various parameters of dynamic posturography. A higher percentage of patients who took more than 15 s had fallen in the previous year than those who took up to 15 s to complete the test [P = 0.012; OR = 2.378; 95% CI (1.183, 4.780)]. No significant correlation was found between the step count and the number of falls in the previous year, with falling during the test or not, or with being a single or a frequent faller. No relation was found between the need for supports and the number of falls, with having or not having fallen in the previous year, or with being a single or frequent faller.

Conclusion: The modified TUG Test is in relation with the presence or absence of falls. Time is the essential parameter for analyzing the risk of falling and the 15-s threshold is a good value to differentiate elderly patients at high risk of falling.

Combined Depression and Malnutrition As an Effective Predictor of First Fall Onset in a Chinese Community-Dwelling Population: A 2-Year Prospective Cohort Study

This study aims to explore the single and joint effects of depression and malnutrition on the incidence of first fall onset in a Chinese community-dwelling elderly population. This cohort study consisted of 739 residents without a history of falls who were aged 60 years and older (mean age: 67.08 ± 5.79 years, female: 58.2%). Depression was defined with the Geriatric Depression Scale (GDS)-30; a score of ≥11 was considered to be depressed, while malnutrition was defined with the Mini Nutritional Assessment where a score <17 was defined as malnourished. Over a 2-year follow-up period, older adults who experienced at least one fall were allocated to the first fall onset group. The prevalence of baseline falls was 21.36%. During the 2-year follow-up, incidence of first fall onset was 13.13%. After adjusting for all confounders, depression alone (adjusted odds ratio [OR] = 3.545, 95% confidence interval [CI] = 1.318-9.535) and malnutrition alone (adjusted OR = 2.204, 95% CI = 1.183-4.108) were observed to be independent risk factors for first fall onset, while comorbidity of depression and malnutrition showed progressively increased risk of promoting first fall (adjusted OR = 8.161, 95% CI = 3.591-18.545) than those with only depression or malnutrition or without both depression and malnutrition. Malnutrition mediated 56% effects in the association between depression and first fall onset, while depression mediated 76% effects in the promoting role of malnutrition in first fall. Depression and malnutrition were found to be independent causes for promoting first fall, while mental health and nutrition should be treated as commonly prior interventions to delay first fall onset. Meanwhile, for malnourished Chinese community-dwelling older adults, avoidance or treatment of depression should be addressed at first.

Predictors of Functional Change in a Skilled Nursing Facility Population

BACKGROUND AND PURPOSE

Inability to obtain sufficient gains in function during a skilled nursing facility (SNF) stay impacts patients' functional trajectories and susceptibility to adverse events. The purpose of this study was to identify predictors of functional change in patients temporarily residing in an SNF following hospitalization.

METHODS

One hundred forty patients admitted to a single SNF from the hospital who had both evaluation and discharge measures of physical function documented were included. Data from the Minimum Data Set 3.0 and electronic medical record were extracted to record clinical and demographic characteristics. The Short Physical Performance Battery (SPPB) was administered by rehabilitation therapists at evaluation and discharge. The SPPB consists of balance tests, gait speed, and a timed 5-time sit-to-stand test.

RESULTS AND DISCUSSION

The Patient Health Questionnaire (PHQ-9) Screening Tool for Depression was the only significant predictor of change in gait speed over an SNF stay. Eighty-seven percent of patients achieved a clinically meaningful change in the SPPB of 1 point or greater from evaluation to discharge, with 78% demonstrating a clinically meaningful change of 0.1 m/s or greater on gait speed. However, 69% of patients demonstrated SPPB scores of 6 points or less and 57% ambulated less than 0.65 m/s at the time of discharge from the SNF, which indicates severe disability.

CONCLUSIONS

Poor physical function following an SNF stay places older adult at significant risk for adverse events including rehospitalization, future disability, and institutionalization. Understanding the predictors of functional change from evaluation to discharge may direct efforts toward developing innovative and effective interventions to improve function trajectories for older adults following an acute hospitalization.

Medo de quedas e força muscular do quadril em idosos independentes da comunidade

RESUMO O medo de quedas pode fazer com que o idoso desenvolva estratégias que alteram o equilíbrio semiestático e dinâmico, predispondo-o a um risco aumentado de cair. A função muscular dos abdutores e adutores de quadril tem importante papel na manutenção da estabilidade postural. Entretanto, não se sabe se idosos com medo de cair apresentam maior comprometimento na função muscular do quadril. Assim, o objetivo foi comparar o pico de torque (PT) isométrico dos músculos abdutores e adutores de quadril entre idosos com e sem medo de quedas. Os participantes foram divididos em dois grupos: com (n=81) e sem (n=81) medo de quedas. O PT dos abdutores e adutores de quadril foi obtido com dinamômetro isocinético (System 4 Pro, Biodex, Nova York, EUA). A comparação do PT dos grupos foi realizada por meio de modelo linear geral univariado, ajustado pelas covariáveis idade, sexo, índice de massa corporal, nível de atividade física e histórico de quedas, utilizando o software SPSS 17.0, com nível de significância de 5%. Não houve diferença do PT abdutor e adutor do quadril entre os grupos após análise univariada com ajustamento. Observou-se que idosos com medo de quedas não apresentam prejuízos na função muscular dos estabilizadores de quadril quando comparados a idosos sem medo de quedas.

Decreased Appetite is Associated with Sarcopenia-Related Outcomes in Acute Hospitalized Older Adults

Decreased appetite is one of the main risk factors of malnutrition. Little is known on how appetite changes during hospitalization and after discharge and how it relates with sarcopenia-related outcomes. We analyzed data of the Hospital-ADL study, a multicenter prospective cohort study that followed 400 acutely hospitalized older adults (≥70 year). Appetite (SNAQ), handgrip strength (Jamar), muscle mass (BIA), mobility (DEMMI), and physical performance (SPPB) were assessed within 48 h of admission, at discharge, and at one and three months post-discharge. The course of decreased appetite was analysed by Generalised Estimating Equations. Linear Mixed Model was used to analyse the associations between decreased appetite and the sarcopenia-related outcomes. Decreased appetite was reported by 51% at hospital admission, 34% at discharge, 28% one month post-discharge, and 17% three months post-discharge. Overall, decreased appetite was associated with lower muscle strength (β = -1.089, p = 0.001), lower mobility skills (β = -3.893, p < 0.001), and lower physical performance (β = -0.706, p < 0.001) but not with muscle mass (β = -0.023, p = 0.920). In conclusion, decreased appetite was highly prevalent among acute hospitalized older adults and remained prevalent, although less, after discharge. Decreased appetite was significantly associated with negative sarcopenia-related outcomes, which underlines the need for assessment and monitoring of decreased appetite during and post hospitalization.

FACTORS ASSOCIATED WITH LOW CONCERN ABOUT FALLING IN PHYSICALLY ACTIVE OLDER PEOPLE

ABSTRACT Introduction: Fear of falling is one of the main consequences of falls in the elderly; therefore, it is important to investigate the factors associated with the reduction of this fear. Objective: The objective of this study consisted of verifying the associated factors that best explain the low concern about falling in physically active older people. Methods: A total of 162 elderly people with a mean age of 69.95 (SD = 6.69) participated in the study. The diagnostic data sheet, the Falls Efficacy Scale-International, the Senior Fitness Test and anthropometric measurements were used to obtain data. Binary Logistic Regression was used in the data analysis to estimate the Odds Ratio (OR) and 95% confidence intervals (95% CI). The p <0.05 Omnibus Test was used to assess the quality of the adjusted model, and the Hosmer-Lemeshow test was applied to verify the explanatory power of the model. Results: In the crude analysis, normal weight elderly subjects (OR = 2.86, 95% CI = 1.32-6.20) with good levels of lower limb strength (OR = 2.64, 95% CI = 1.38-5.06), are more likely to have low fear of falling. In the adjusted analysis, the model was able to explain 75% of endpoint occurrence. Conclusion: It is concluded that among the variables analyzed, age, BMI and lower limb strength best explain the low concern about falling in the elderly. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference “gold” standard.

Mental Well-Being of Older People in Finland during the First Year in Senior Housing and Its Association with Physical Performance

Growing numbers of older people relocate to senior housing, when their physical or mental performance declines. The relocation is known to be one of the most stressful events in the life of older people and affect their mental and physical well-being. More information about the relationships between mental and physical parameters is required. We examined self-reported mental well-being of 81 older people (aged 59⁻93, living in northern Finland), and changes in it 3 and 12 months after relocation to senior housing. The first measurement was 3 months and the second measurement 12 months after relocation. Most participants were female (70%). Their physical performance was also measured, and associations between these two were analyzed. After 12 months, mental capability was very good or quite good in 38% of participants, however 22% of participants felt depressive symptoms daily or weekly. Moreover, 39% of participants reported daily or weekly loneliness. After 12 months participants reported a significant increase in forgetting appointments, losing items and difficulties in learn new things. They felt that opportunities to make decisions concerning their own life significantly decreased. Furthermore, their instrumental activities of daily living (IADL), dominant hand’s grip strength and walking speed decreased significantly. Opportunities to make decisions concerning their life, feeling safe, loneliness, sleeping problems, negative thoughts as well as fear of falling or having an accident outdoors were associated with these physical parameters. In addition to assessing physical performance and regular exercise, the various components of mental well-being and their interactions with physical performance should be considered during adjustment to senior housing.

Multi-directional reach test in South Asian children: Normative reference scores from 5 year to 12 years old

Multi-directional reach test (MRT) emerged as a valid and reliable assessment tool for balance evaluation among elderly. The normative reference scores have been established in adults and elderly people, but they were not yet established for children. Hence, we aimed at establishing the normative reference scores of MRT among the school going children aged between 5 and 12 years. Children (N = 194; 124 males, 70 females) were recruited by the stratified random sampling for the normative study. MRT was performed by the custom made, multi-directional reach estimator. MRE device consists of three adjustable wooden frames with two metallic rulers each of 600 mm. Children were asked to reach maximum distance in forward reach (FR), backward reach (BR), right lateral reach (RLR) and left lateral reach (LLR) directions to obtain their maximum reaching ability. The mean of three readings were used to report the normative reference scores of MRT. Median age, height, weight and body mass index (BMI) were 8.5 years, 1240 mm, 27 kg and 17.24 kg/m² respectively. The normative reference scores [median (95% confidence Interval, CI)] of MRT among the children aged 5-12 years old were FR [169.7 mm (CI, 166.1-183.3 mm)], BR [77.7 mm (CI, 78.0-85.5 mm)], RLR [122.0 mm (119.6-130.9 mm)] and LLR [107.0 (105.8-119.3 mm)] respectively.

Reliability and Validity of the Short Falls Efficacy Scale International in English, Mandarin, and Bahasa Malaysia in Malaysia

While the prevalence of falls among Malaysian older adults is comparable to other older populations around the world, little is currently known about fear of falling in Malaysia. The Falls Efficacy Scale International (FES-I) and short FES-I scales to measure fear of falling have not yet been validated for use within the Malaysian population, and are currently not available in Bahasa Malaysia (BM). A total of 402 participants aged ≥63 years were recruited. The questionnaire was readministered to 149 participants, 4 to 8 weeks after the first administration to determine test–retest reliability. The original version of the 7-item short FES-I is available in English, while the Mandarin was adapted from the 16-item Mandarin FES-I. The BM version was translated according to protocol by four experts. The internal structure of the FES-I was examined by factor analysis. The 7-item short FES-I showed good internal reliability and test–retest reliability for English, Mandarin, and BM versions for Malaysia.

Wii Fit is effective in women with bone loss condition associated with balance disorders: a randomized controlled trial

The use of exergame for balance competencies was recently explored in women affected by balance ability reduction with non-conclusive results. The aim of the study was to evaluate the efficacy of a supervised exergame performed with the Wii Fit^® compared to conventional exercises on balance function, quality of life, fear of fall and well-being in women with bone loss. Thirty-eight female participants aged over 65 years, with a bone loss condition, were enrolled and random allocated in the Wii group or control group. Subject enrolled in Wii group performed a balance training with a Wii Fit supervised by a physiotherapist (1 h, 2 days per week, during 8 weeks) while in control subjects performed the same amount of conventional balance exercises. Subject enrolled in experimental group showed significantly higher scores in terms of Berg Balance Scale (p = 0.027). In SF-36 scores, a significant difference was reported for physical activity score after treatment (p = 0.031). Fear of falling and the psychological scales were not significantly different between the two groups. In women with bone loss condition, a supervised Wii Fit training has shown better efficacy in improving balance performance with respect to conventional balance exercises.

Effects of short-term Nordic walking training on sarcopenia-related parameters in women with low bone mass: a preliminary study

Background

Several studies have demonstrated the positive effects of physical activity on skeletal muscle mass and muscle strength in women with osteoporosis. However, the impact of Nordic walking training on sarcopenia-related parameters in women with low bone mass remains unknown. Therefore, the purpose of this study was to evaluate the impact of 12 weeks of Nordic walking training on skeletal muscle index, muscle strength, functional mobility, and functional performance in women with low bone mass.

Materials and methods

The participants were 45 women, aged 63–79 years, with osteopenia or osteoporosis. The subjects were randomly assigned either to an experimental group (12 weeks of Nordic walking training, three times a week) or to a control group. Skeletal muscle mass and other body composition factors were measured with octapolar bioimpedance InBody 720 analyser. Knee extensor and flexor isometric muscle strength were measured using Biodex System 4 Pro™ dynamometers. This study also used a SAEHAN Digital Hand Dynamometer to measure handgrip muscle strength. The timed up-and-go test was used to measure functional mobility, and the 6-minute walk test was used to measure functional performance.

Results

Short-term Nordic walking training induced a significant increase in skeletal muscle mass (P=0.007), skeletal muscle index (P=0.007), strength index of the knee extensor (P=0.016), flexor (P<0.001), functional mobility (P<0.001), and functional performance (P<0.001) and a significant decrease in body mass (P=0<006), body mass index (P<0.001), and percent body fat (P<0.001) in participants. Regarding handgrip muscle strength, no improvement was registered (P=0.315). No significant changes in any of the analyzed parameters were observed in the control group.

Conclusion

Overall, short-term Nordic walking training induces positive changes in knee muscle strength and functional performance in women with low bone mass. This finding could be applied in clinical practice for intervention programs in women with osteopenia and osteoporosis.

The effects of objectively measured physical activity and fitness on fear of falling among Korean older women

We examined the effects of objectively measured physical activity (PA) and physical fitness (PF) on fear of falling (FOF) among older adults. The subjects were 94 Korean females aged 65–79. PA was measured with accelerometers, PF with the senior fitness test and FOF with the Korean Survey of Activities and Fear of Falling in the Elderly. With the subjects’ age, number of chronic conditions, and history of falls included as correction factors, a multiple regression analysis showed that PA (P=0.016) and agility/dynamic balance measured by the 8-foot up-and-go test (UNG) (P=0.001) significantly influenced FOF. The FOF of the slowest UNG quartile was significantly higher than those of other groups (P=0.002). This study concludes that among female older adults agility/dynamic balance as measured by UNG is the main factor impacting FOF and individuals with markedly low UNG tend to have high FOF.

Fear of falling associated with sociodemographic and lifestyle variables and clinical conditions in elderly people registered with the Family Health Strategy in Campo Grande, Mato Grosso do Sul

Abstract Objective: To investigate the prevalence of fear of falling among the elderly and its association with sociodemographic and lifestyle variables, morbidities, balance, mobility and a history of falls (HF). Method: A cross-sectional study was performed in nine family health units in the southern district of Campo Grande, Mato Grosso do Sul. An interview was conducted to obtain data relating to the sociodemographic and clinical variables and the history of falls. The Falls Efficacy Scale-International-Brazil (FES-I-Brazil) and the Timed Up and Go (TUG) test were also applied. Statistical analysis was performed using the Pearson linear correlation test (FES-I-Brazil related to TUG score), the Student's t-test (FES-I-Brazil related to lifestyle, comorbidities and HF) and ANOVA one way, followed by Tukey post-hoc (FES-I-Brazil related to HF and TUG score). Results: Two hundred and one elderly persons with an average age of 70.85 (±7.72) years were included. On the FES-I-Brazil scale, the overall score was 28.80 (±0.82) points. The average TUG time was 12.00 (±0.57) seconds. There was a significant positive linear correlation between the FES-I-Brazil score and the TUG time (p<0.001) and the variables of gender (p=0.008), hypertension (p=0.002), FH (p=0.005) and frequency of falls (p=0.011). Conclusion: There is a high frequency of fear of falling among the studied population, as the majority reported fear of falling in at least one of the sixteen FES-I-Brazil tasks. Such fear was significantly associated with hypertension, diabetes mellitus, history of falls, perception of always suffering falls and low scores for mobility and balance.

The geriatric depression scale and the timed up and go test predict fear of falling in community-dwelling elderly women with type 2 diabetes mellitus: a cross-sectional study

Background

Fear of falling is a common and potentially disabling problem among older adults. However, little is known about this condition in older adults with diabetes mellitus. The aims of this study were to investigate the impact of the fear of falling on clinical, functional and gait variables in older women with type 2 diabetes and to identify which variables could predict the fear of falling in this population.

Methods

Ninety-nine community-dwelling older women with type 2 diabetes (aged 65 to 89 years) were stratified in two groups based on their Falls Efficacy Scale-International score. Participants with a score < 23 were assigned to the group without the fear of falling (n = 50) and those with a score ≥ 23 were assigned to the group with the fear of falling (n = 49). Clinical data included demographics, anthropometrics, number of diseases and medications, physical activity level, fall history, frailty level, cognition, depressive symptoms, fasting glucose level and disease duration. Functional measures included the Timed Up and Go test (TUG), the five times sit-to-stand test (5-STS) and handgrip strength. Gait parameters were obtained using the GAITRite® system.

Results

Participants with a fear of falling were frailer and presented more depressive symptoms and worse performance on the TUG and 5-STS tests compared with those without a fear of falling. The group with the fear of falling also walked with a lower velocity, cadence and step length and increased step time and swing time variability. The multivariate regression analysis showed that the likelihood of having a fear of falling increased 1.34 times (OR 1.34, 95 % CI 1.11–1.61) for a one-point increase in the Geriatric Depression Scale (GDS-15) score and 1.36 times (OR 1.36, 95 % CI 1.07–1.73) for each second of increase in the TUG performance.

Conclusions

The fear of falling in community-dwelling older women with type 2 diabetes mellitus is associated with frailty, depressive symptoms and dynamic balance, functional mobility and gait deficits. Furthermore, both the GDS-15 and the TUG test predict a fear of falling in this population. Therefore, these instruments should be considered during the assessment of diabetic older women with fear of falling.

Age-associated declines in muscle mass, strength, power, and physical performance: impact on fear of falling and quality of life

This 3-year longitudinal study among older adults showed that declining muscle mass, strength, power, and physical performance are independent contributing factors to increased fear of falling, while declines of muscle mass and physical performance contribute to deterioration of quality of life. Our findings reinforce the importance of preserving muscle health with advancing age.

INTRODUCTION

The age-associated loss of skeletal muscle quantity and function are critical determinants of independent physical functioning in later life. Longitudinal studies investigating how decrements in muscle components of sarcopenia impact fear of falling (FoF) and quality of life (QoL) in older adults are lacking.

METHODS

Twenty-six healthy older subjects (age, 74.1 ± 3.7; Short Physical Performance Battery (SPPB) score ≥10) and 22 mobility-limited older subjects (age, 77.2 ± 4.4; SPPB score ≤9) underwent evaluations of lower extremity muscle size and composition by computed tomography, strength and power, and physical performance at baseline and after 3-year follow-up. The Falls Efficacy Scale (FES) and Short Form-36 questionnaire (SF-36) were also administered at both timepoints to assess FoF and QoL, respectively.

RESULTS

At 3-year follow-up, muscle cross-sectional area (CSA) (p < 0.013) and power decreased (p < 0.001), while intermuscular fat infiltration increased (p < 0.001). These decrements were accompanied with a longer time to complete 400 m by 22 ± 46 s (p < 0.002). Using linear mixed-effects regression models, declines of muscle CSA, strength and power, and SPPB score were associated with increased FES score (p < 0.05 for each model). Reduced physical component summary score of SF-36 over follow-up was independently associated with decreased SPPB score (p < 0.020), muscle CSA (p < 0.046), and increased 400 m walk time (p < 0.003).

CONCLUSIONS

In older adults with and without mobility limitations, declining muscle mass, strength, power, and physical performance contribute independently to increase FoF, while declines of muscle mass and physical performance contribute to deterioration of QoL. These findings provide further rationale for developing interventions to improve aging muscle health.

Association of Physical Performance and Pain With Fear of Falling Among Community-Dwelling Japanese Women Aged 65 Years and Older

Our aim was to explore the association of physical performance and pain with fear of falling among community-dwelling Japanese women.The subjects were 278 women aged 65 years and over. We collected information on fear of falling, painful joints, comorbidities, falls in the previous year, and cataracts. Walking time (distance of 6 m), chair stand time (5 times), grip strength, the timed up and go test (TUG), and functional reach were measured.The prevalence of fear of falling was 36.3%, and it increased with age, but it was not significant (P = 0.081). Multivariate logistic regression analysis showed that poor physical performance (longer walking time, longer chair stand time, weaker grip strength, and longer TUG) and pain (low back, and upper and lower extremity pain) were significantly associated with fear of falling after adjusting for age, body mass index, comorbidities, falls in the previous year, and cataracts.Maintaining physical functioning and managing pain may be important for elderly women with fear of falling.

Fear of falling in people with chronic obstructive pulmonary disease

BACKGROUND

Increased fear of falling (FOF) has been associated with impaired physical function, reduced physical activity and increased fall risk in older adults. Preliminary evidence suggests that individuals with chronic obstructive pulmonary disease (COPD) may have an increased FOF. This study aims to compare the level of FOF in people with COPD with healthy controls, and to determine the associations between FOF and measures of physical function, physical activity and fall risk in COPD.

METHODS

FOF was assessed in 40 participants with COPD and 25 age- and gender-matched controls using the Falls Efficacy Scale-International (FES-I). Physical function was evaluated using quadriceps hand-held dynamometry, the Berg Balance Scale and the Six-minute Walk Test. Associations between FOF, physical activity and fall risk were evaluated using the Physical Activity Scale for the Elderly and the Falls Risk in Older People - Community Setting. Pearson's correlation coefficient and stepwise multivariate linear regression were used.

RESULTS

Individuals with COPD (mean ± SD; age: 71 ± 8 years, FEV1: 45 ± 16 %pred) had higher FOF compared to controls (FES-I: 25.0 ± 7.9 vs 20.2 ± 5.2, p=0.01). Higher FOF was associated with lower quadriceps strength (p=0.02) and an impaired balance (p < 0.01); these explained 26% of the FOF variance. Reduced levels of physical activity (p=0.01) and a higher fall risk (p < 0.01) were associated with an increased FOF in COPD.

CONCLUSION

People with COPD have a higher FOF compared to the healthy peers, which is related to lower quadriceps muscle strength, impaired balance, lower levels of physical activity and an increased fall risk.
