Background and purpose: Falling among older adults is common and can cause chronic health complications. Fear of falling, a lasting concern about falling that can lead an individual to avoid activities he or she can perform, is strongly associated with falling and fall risk. Although White older adults fall more often, Black older adults have more fall risk factors. The purpose of this study was to investigate factors that explain fear of falling and differences between White and Black community-dwelling older adults in fear of falling, balance confidence, and fall risk factors.

Methods: Using a cross-sectional, retrospective design, 84 community-dwelling older adults (mean age [SD] = 69.0 [5.2], range: 55-80; White, n = 37, 44%; Black, n = 47, 56%, M/F = 20/64) were assessed. Assessments were conducted in a laboratory for human studies. Fall history and risk factors, and subjective fear of falling, were collected. The Montreal Cognitive Assessment (MoCA), Activities-Specific Balance Confidence (ABC) score, preferred, backward, and fast Gait Speed, Short Form-12 Physical and Mental Component Scores, fear of falling rating scale, and demographics questionnaires were administered. Analyses included a proportional odds logistic regression model to examine which factors predicted ABC score and which factors were associated with subjective fear of falling, 1-way analysis of variance for continuous variables, the Fisher exact test for categorical variables, and the Mann-Whitney-Wilcoxon test for ordinal variables.

Results: Black participants had significantly fewer years of education ( P = .007), lower MoCA scores ( P = .002), and slower fast gait speed ( P = .032) than White participants. Black participants reported less subjective fear of falling ( P = .043). In the final ABC model (Akaike information criterion 208.26), lower ABC scores were predicted by White race, slower preferred and fast gait speeds, and worse Short Form-12 Mental Composite Scores.

Discussion: Despite Black participants demonstrating typical characteristics of higher fall risk including lower cognitive scores, slower gait speed, and lower ABC scores, Black participants reported fewer falls. Understanding racial differences is an important factor in fear of falling and balance confidence.

Conclusion: Reasons for racial differences should be examined further in fear of falling and balance confidence to facilitate the development of patient-centered falls prevention physical therapy programs.

Background and purpose: The First-time Injurious Fall (FIF) screening tool was created to identify fall risk in community-living older men and women, who may be targets for primary preventive interventions. The FIF tool consists of 3 self-reported questions and 1 physical test (1-leg standing balance). The purpose of this study was to examine the predictive ability of the FIF tool and a modified FIF tool (in which 1-leg standing is replaced by self-reported balance) for first-time injurious falls.

Methods: A cohort of 1194 community-living people 60 years and older from the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), Sweden, was followed longitudinally for 5 years. Data on injurious falls were collected from registered data and were defined as receipt of care after a fall. The predictive ability of the FIF tool and the m-FIF tool was explored using Harrell's C statistic, stratified by sex.

Results and discussion: The injurious fall rate per 1000 person-years was 54.9 (95% CI: 47.22-63.78) for women and 36.3 (95% CI: 28.84-45.78) for men. The predictive ability for women and men according to Harrell's C statistic was 0.70 and 0.71 for the FIF tool and the m-FIF tool. The predictive ability was 0.70 and 0.69 for 1-leg standing, and 0.65 and 0.60 for self-reported balance problems.

Conclusions: The m-FIF tool presented similar predictive ability as the FIF tool regarding first-time injurious falls. This finding could extend the usefulness of the tool to other settings, such as to electronic health (eHealth). A quickly and easily administered screening tool can help physical therapists to identify people with a high risk of falling who may need to undergo a more comprehensive fall risk assessment.

Background and purpose: With an aging population, falls have become an increasing public health concern. While face-to-face exercise programs have demonstrated efficacy in reducing falls, their effectiveness is hampered by low participation and adherence. Digital technologies are a novel and potentially effective method for delivering tailored fall prevention exercise programs to older adults. In addition, they may increase the reach, uptake, and sustainability of fall prevention programs. Therefore, understanding older adults' experiences of using technology-driven methods is essential. This study explored the user experience of StandingTall , a home-based fall prevention program delivered through a tablet computer.

Methods: Fifty participants were recruited using purposive sampling, from a larger randomized controlled trial. Participants were selected to ensure maximum variability with respect to age, gender, experience with technology, and adherence to the program. Participants undertook a one-on-one structured interview. We followed an iterative approach to develop themes.

Results and discussion: Eight themes were identified. These fall under 2 categories: user experience and program design. Participants found StandingTall enjoyable, and while its flexible delivery facilitated exercise, some participants found the technology challenging. Some participants expressed frustration with technological literacy, but most demonstrated an ability to overcome these challenges, and learn a new skill. Older adults who engaged in a technology-driven fall prevention program found it enjoyable, with the flexibility provided by the online delivery central to this experience. While the overall experience was positive, participants expressed mixed feelings about key design features. The embedded behavior change strategies were not considered motivating by most participants. Furthermore, some older adults associated the illustrated characters with gender-based stereotypes and negative views of aging, which can impact on motivation and preventive behavior.

Conclusion: This study found digital technologies are an effective and enjoyable method for delivering a fall prevention program. This study highlights that older adults are interested in learning how to engage successfully with novel technologies.

Background and purpose: Because of its high prevalence and association with negative health-related outcomes, frailty is considered one of the most important issues associated with human aging and its mitigation is among the essential public health goals for the 21st century. However, very few studies have focused on institutionalized older adults, despite the knowledge that frailty can be reversible when identified and treated from its earliest stages. Therefore, the objective of this study was to evaluate the effects of a supervised group-based multicomponent exercise program intervention with or without oral nutritional supplementation on functional performance in frail institutionalized older adults.

Methods: This was a multicenter randomized controlled trial study with a 6-month intervention period. A total of 111 frail institutionalized older adults (75 years or older) who met at least 3 of the 5 Fried frailty criteria were randomly allocated to the control group (CG; n = 34, mean age = 87.3 ± 5.3 years), a supervised group-based multicomponent Otago Exercise Program group (OEP; n = 39, mean age = 86 ± 5.9 years), or a supervised group-based multicomponent exercise program intervention with oral nutritional supplementation (OEP+N; n = 38, mean age = 84.9 ± 6 years). Measurements included the Timed Up and Go test (TUG), Berg Balance Scale (BBS), Short Physical Performance Battery, repeated chair stand test (STS-5), handgrip strength (HGS), 10-m walking test, and 6-minute walking test, both at baseline and after the 6-month intervention period.

Results and discussion: The between-group analysis by 2-way analysis of covariance showed significant improvement in the TUG [{OEP vs CG: -8.2 seconds, 95% CI [-13.3 to -2.9]; P < .001}; {OEP vs OEP+N: -7.3 seconds, 95% CI [-12.4 to -2.2]; P = .002}], BBS [{OEP vs CG; 8.2 points, 95% CI [5.2 to 11.2]; P < .001}; [{OEP+N vs CG: 4.6 points, 95% CI [1.6 to 7.6]; P < .001}; {OEP vs OEP+N: 3.5 points, 95% CI [0.6 to 6.5]; P = .011}], and HGS [{OEP vs CG: 3.4 kg, 95% CI [1.5 to 5.3]; P < .001}; {OEP+N vs CG: 3.6 kg, 95% CI [1.7 to 5.5]; P < .001}]. Additionally, the within-group analysis showed a significant improvement in the TUG (-6.9 seconds, 95% CI [-9.8 to -4.0]; P < .001) and BBS (4.3 points, 95% CI [2.6 to 5.9]; P < .001) in the OEP group. A significant decrease in the BBS and HGS was shown in the CG.

Conclusions: A 6-month supervised group-based multicomponent exercise intervention improved the levels of mobility, functional balance, and HGS in frail institutionalized older adults. Further research will be required to evaluate the nutritional supplementation effects on functional performance to better determine its clinical applicability for tackling frailty.

Background and purpose: Falls are a common and persistent concern among people with neurological disorders (PwND), as they frequently result in mobility deficits and may lead to loss of functional independence. This study investigated the ceiling and floor effects, internal consistency, and convergent validity of 2 patient-reported fall prevention strategy scales in PwND.

Methods: This is a prospective cohort study. Two-hundred and ninety-nine PwND (111 people with multiple sclerosis, 94 people with Parkinson's disease, and 94 people with stroke) were seen for rehabilitation and assessed. The number of retrospective and prospective falls, use of walking assistive devices, scores on the Fall Prevention Strategy Survey (FPSS), Falls Behavioural Scale (FaB), and balance and mobility scales (Berg Balance Scale, Dynamic Gait Index, Timed Up and Go, 10-m walking test, and Activities-specific Balance Confidence) were analyzed.

Results: Total score distributions showed negligible ceiling and floor effects for both the FPSS (ceiling: 0.3%, floor: 0.3%) and the FaB (ceiling: 0%, floor: 0%). The Cronbach α (CI) was of 0.87 (0.85-0.89) for the FPSS and 0.86 (0.84-0.88) for the FaB. In terms of convergent validity, the FPSS and FaB were moderately correlated (Spearman correlation coefficient = 0.65). Moreover, the correlations between the FPSS and FaB and balance and mobility scales ranged from 0.25 to 0.49 ( P < .01). Both scales are slightly better able to distinguish between retrospective fallers/nonfallers [area under the curve, AUC (95% CI): FPSS: 0.61 (0.5-0.7); FaB: 0.60 (0.5-0.6)] compared with prospective fallers/nonfallers [AUC (95% CI): FPSS: 0.56 (0.4-0.6); FaB: 0.57 (0.4-0.6)]. Both scales accurately identified individuals who typically required the use of a walking assistive device for daily ambulation [AUC (95% CI): FPSS: 0.74 (0.7-0.8); FaB: 0.69 (0.6-0.7)]. Multiple regression analysis showed that previous falls, use of an assistive device, and balance confidence significantly predicted participants' prevention strategies (FPSS: R2 = 0.31, F(8,159) = 10.5, P < .01; FaB: R2 = 0.31, F(8,164) = 10.89, P < .01).

Conclusion: The FPSS and the FaB appear to be valid tools to assess fall prevention strategies in people with neurological disorders. Both scales provide unique and added value in providing information on individual behavior for fall prevention.

Background and purpose: Diminished pulmonary function is associated with negative health outcomes and pulmonary impairment, and can be associated with frailty. The objectives of this study were to compare pulmonary function between frail, prefrail, and nonfrail older adults; to verify the association between pulmonary function and frailty syndrome; and to establish cut-off points for pulmonary function variables for predicting frailty.

Methods: A cross-sectional study was conducted with 379 community-dwelling older adults of both sexes. Spirometry was used to measure pulmonary function criteria (forced vital capacity, FVC; forced expiratory volume in 1 second, FEV 1 ; and FEV 1 /FVC ratio). The presence of frailty was evaluated with Fried's frailty phenotype. Statistical analysis included a multinomial logistic regression model. Pulmonary function cut-off points for discriminating frailty syndrome were established through analysis of the receiver operating characteristic curves.

Results and discussion: The study participants were a median of 69.0 (64.0-74.0) years old, and 12.4% presented frailty while 58% presented prefrailty. Frail and prefrail older adults presented significantly lower median FVC and FEV 1 values-FVC = 1.89 L (1.45-2.31) and FEV 1 = 1.60 L (1.24-1.91); FVC = 2.07 L (1.62-2.67) and FEV 1 = 1.66 L (1.32-2.09), respectively-than nonfrail participants-FVC = 2.53 L (1.96-3.16) and FEV 1 = 2.01 L (1.54-2.43). The adjusted analysis indicated that FEV 1 (odds ratio [OR] = 0.63; 95% confidence interval [CI], 0.39-0.99) and the FVC (OR = 0.68; 95% CI, 0.48-0.96) were inversely associated with prefrailty and that FVC (OR = 0.52; 95% CI, 0.29-0.94) was associated with frailty. Cut-off points for prefrailty (FVC ≤2.3 L and FEV 1 ≤1.86 L) and frailty (FVC ≤2.07 L and FEV 1 ≤1.76 L) were established.

Conclusions: Pulmonary function was lower in frail and prefrail older adults than in their nonfrail peers. Frailty and prefrailty were inversely associated with pulmonary function. Cut-off points for FEV 1 and FVC for discriminating frailty were established and may allow pulmonary function to serve as an indicator of frailty in older adults.

Background and purpose: The present study aimed to assess the concurrent validity of the International Classification of Functioning, Disability and Health (ICF) core set to classify physical health of older adults in relation to self-rated health.

Methods: This is a methodological study conducted in Santa Cruz, Rio Grande do Norte (RN) state, in Northeastern Brazil, with 101 community-dwelling older adults. The participants rated their health status, which was classified into 3 groups: very good, fair, and poor/very poor. An interview was then conducted using self-reported and objective measurements to classify physical health according to the ICF core set. It consists of 30 categories, 14 of which belong to the body function (b) component, 4 to body structures (s), 9 to activities and participation (d), and 3 related to environmental factors (e). To analyze the compromised and problematic categories in the ICF, an impairment index was created for each component. The relationship between self-rated health and the impairment indexes was assessed using the multinomial logistic regression test adjusted for age, sex, schooling, and perception of income sufficiency.

Results: A greater likelihood of poor or very poor self-rated health was found in older individuals with the highest impairment index in (b) (odds ratio [OR] = 1.18; P < .001); (s) (OR = 1.11; P ≤ .001); (d) capacity (OR = 1.09; P = .02); and (d) performance (OR = 1.08; p = 0.01).

Conclusion: The results suggest that the ICF core set is a valid instrument to assess the physical health of older adults, since it is associated with self-rated health and shows potential for use in clinical practice and scientific research, with universal language regarding functionality and physical health in older adults.

Background and purpose: Older adults with chronic obstructive pulmonary disease (COPD) are at risk for physical and cognitive impairment. Cognitive function is associated with falls in older adults. However, it is unknown whether a relationship exists between cognitive function and falls in patients with COPD. The aim of this study was to examine the relationships between cognitive function, balance, and gait speed in older adults with COPD.

Patients and methods: A secondary analysis was performed using data from the 2010 wave of the Health and Retirement Study (HRS). Cognitive (immediate and delayed recall, executive function) and physical (gait speed, tandem balance time) measure data were extracted for older adults with COPD (n = 382) and an age-matched control group without COPD (n = 382) who met inclusion/exclusion criteria. Multivariate linear regression modeling was performed to examine associations between cognitive function and mobility or balance while controlling for age, gender, body mass index, grip strength, and education.

Results: In older adults with COPD, delayed recall was significantly associated with tandem balance performance (β= 1.42, P < .05). Other cognitive measures were not associated with gait speed or balance.

Conclusion: In older adults with COPD, one of four cognitive functions was associated with a static standing balance task. Screening of cognitive function, specifically delayed recall, should be a part of the management of falls in this population.
