Prediction of fear of falling at 6 months after stroke based on 279 individuals from the Fall Study of Gothenburg

Experiencing Cerebrovascular Diseases like Stroke and Fear of Falling: Longitudinal Results from the Survey of Health, Ageing and Retirement in Europe

Objective: The aim of this study was to clarify the link between experiencing cerebrovascular diseases (strokes as an explicit example) and fear of falling (FOF) among middle-aged and older adults in Europe. Methods: Longitudinal data were used from wave 5 to wave 7 of the representative Survey of Health, Ageing and Retirement in Europe (SHARE). Self-reported tools were used to quantify the key variables. Fear of falling was similarly assessed using a dichotomous yes or no question, "For the past six months at least, have you been bothered by any of the health conditions on this card", with fear of falling being one of the options. It was adjusted for various sociodemographic and health-related factors. In particular, to account for unobserved heterogeneity, conditional fixed effect regressions (FE) were used. Accordingly, change in an individual's FOF status over the included waves was analysed and correlated with the reported change of all the included time-varying independent variables within the same individual, including experiencing stroke or other cerebrovascular diseases. The final analytical sample equalled n = 22.071 observations. Results: Conditional logistic FE regressions showed that the onset of a stroke or other forms of cerebrovascular disease was not associated with an increased likelihood of experiencing fear of falling (OR = 1.25, p = 0.095). However, stratified by sex, such an association was present in men (OR = 1.79, p = 0.006), though not in women (OR = 0.94, p = 0.732). Conclusions: The onset of a stroke or other cerebrovascular diseases was associated with an increased likelihood of experiencing FOF in men but not women. Efforts are required to assist older men in avoiding FOF after the onset of stroke or other cerebrovascular pathologies.

Contributing factors and interventions for fear of falling in stroke survivors: a systematic review

OBJECTIVES

The purpose of this study was to provide a comprehensive overview of the prevalence, measurement tools, influencing factors, and interventions for fear of falling (FOF) in stroke survivors.

METHODS

A PRISMA-guided systematic literature review was conducted. PubMed, EMBASE, Cochrane, and Web of Science were systematically searched. The search time was up to February 2023. All observational and experimental studies investigating FOF in stroke patients were included. The assessment tool of the Joanna Briggs Institute was used to assess the quality of the included studies and the risk of bias assessment. (PROSPERO: CRD42023412522).

RESULT

A total of 25 observational studies and 10 experimental studies were included. The overall quality of the included studies was "low" to "good." The most common tool used to measure the FOF was the Falls Efficacy Scale-International (FES-I). The prevalence of FOF was 42%- 93.8%. Stroke survivors with physical impairments have the highest prevalence of FOF. The main risk factors for the development of FOF in stroke survivors were female gender, use of assistive devices, balance, limb dysfunction, and functional mobility. The combination of cognitive behavioral and exercise interventions is the most effective strategy.

CONCLUSIONS

This review suggests that the prevalence of FOF in stroke survivors is high and that understanding the factors associated with FOF in stroke patients can help develop multifactorial prevention strategies to reduce FOF and improve quality of life. In addition, a uniform FOF measurement tool should be used to better assess the effectiveness of interventions for stroke survivors.

Fear of falling: Scoping review and topic analysis using natural language processing

Fear of falling (FoF) is a major concern among older adults and is associated with negative outcomes, such as decreased quality of life and increased risk of falls. Despite several systematic reviews conducted on various specific domains of FoF and its related interventions, the research area has only been minimally covered by scoping reviews, and a comprehensive scoping review mapping the range and scope of the research area is still lacking. This review aims to provide such a comprehensive investigation of the existing literature and identify main topics, gaps in the literature, and potential opportunities for bridging different strains of research. Using the PRISMA-ScR guidelines, we searched the Cochrane Database of Systematic Reviews, CINAHL, Embase, MEDLINE, PsycInfo, Scopus, and Web of Science databases. Following the screening process, 969 titles and abstracts were chosen for the review. Pre-processing steps included stop word removal, stemming, and term frequency-inverse document frequency vectorization. Using the Non-negative Matrix Factorization algorithm, we identified seven main topics and created a conceptual mapping of FoF research. The analysis also revealed that most studies focused on physical health-related factors, particularly balance and gait, with less attention paid to cognitive, psychological, social, and environmental factors. Moreover, more research could be done on demographic factors beyond gender and age with an interdisciplinary collaboration with social sciences. The review highlights the need for more nuanced and comprehensive understanding of FoF and calls for more research on less studied areas.

Relationship between fear of falling and fall risk among older patients with stroke: a structural equation modeling

BACKGROUND

With reduced balance and mobility, older patients with stroke are more susceptible to fear of falling (FOF). A maladaptive form of FOF can cause excessive activity restriction, poor balance, and recurrent falls, forming a self-reinforcing vicious cycle. This study applied and adapted the FOF model to investigate the interaction between FOF and fall risk in older stroke patients.

METHODS

A cross-sectional study was conducted among 302 older stroke patients aged 60 and over. All participants were invited to complete the FOF, fall risk, physical activity, and balance tests, which were measured by the Falls Efficacy Scale International (FES-I), Self-Rated Fall Risk Questionnaire (FRQ), the long-form International Physical Activity Questionnaire (IPAQ-LF) and the Four-Stage Balance Test (FSBT) respectively. Data were analyzed using structural equation modeling.

RESULTS

The mean age of the respondents was 68.62 ± 7.62 years; 8.94% reported a high level of FOF, and 18.21% reported a moderate level of FOF. The structural equation model showed that FOF was directly associated with fall risk (β=-0.38, p < 0.001), and was indirectly associated with fall risk via physical activity (β=-0.075, p < 0.05) and balance ability (β=-0.123, p < 0.05). Depression (β=-0.47, p < 0.001), fall history (β=-0.13, p < 0.05), and female sex (β=-0.16, p < 0.05) affected FOF, while anxiety was not associated with FOF.

CONCLUSIONS

The increased risk of falling in older stroke patients results from a maladaptive FOF affected by depression, fall history, poor balance ability, and limited physical activity. Our results suggest that greater attention should be paid to FOF during stroke recovery and fall prevention. A multifaced intervention program encompassing physiological and psychological factors should be designed to address FOF and prevent falls.

Fatigue in stroke survivors: a 5-year follow-up of the Fall study of Gothenburg

Longer term knowledge of post-stroke fatigue (PSF) is limited. Our aim was to describe the prevalence of, and to identify baseline predictors associated with, PSF 5 years after stroke. We undertook a follow-up of stroke survivors from the 504 consecutively recruited participants in the observational "The Fall Study of Gothenburg", conducted between 2014 and 2016. The dependent variable, PSF, was assessed using the Swedish version of the Fatigue Assessment Scale (S-FAS) and defined as having a S-FAS score ≥ 24. The S-FAS questionnaire was mailed to potential participants in August 2020. The independent variables, previously obtained from medical records, included age; sex; comorbidities; stroke severity; hospital length of stay; body mass index (BMI); number of medications and lifestyle factors at index stroke. To identify predictors of PSF, univariable and multivariable logistic regression analyses were performed. Of the 305 eligible participants, 119 (39%) responded with complete S-FAS. Mean age at index stroke was 71 (SD 10.4) years and 41% were female. After a mean of 4.9 years after stroke, the prevalence of PSF was 52%. Among those with PSF, almost two thirds were classified as having both physical and mental PSF. In the multivariable analysis, only high BMI predicted PSF with an odds ratio of 1.25 (95% CI 1.11-1.41, p < 0.01). In conclusion, half of the participants reported PSF 5 years after index stroke and higher body mass index was identified as a predictor. The findings from this study are important for healthcare professionals, for planning health-related efforts and rehabilitation of stroke survivors.ClinicalTrials.gov, Identifier NCT02264470.

Risk factors for fear of falling in stroke patients: a systematic review and meta-analysis

OBJECTIVE

Even though 32%-83% for fear of falling (FoF) in patients with stroke, very little is known about the predictors of the problems. Therefore, we systematically reviewed the literature on risk factors for FoF in patients with stroke.

DESIGN

A systematic review and meta-analysis DATA SOURCES: PubMed, Embase, Cochrane Library database, Web of Science, CINAHL, PsycINFO, Grey literature and other relevant databases for related publications were searched (from inception to 17 July 2021).

RESULTS

Eight studies involving 1597 participants were selected to analyse risk factors for patients with stroke with FoF. The quality of all included studies was assessed and categorised as medium or high quality. Review Manager V.5.3 merged the OR value and 95% CI of the potential risk factors. Meta-regression and Egger's test were performed by Stata V.15.1. The risk factors for FoF in patients with stroke were women (OR=2.13, 95% CI 1.47 to 3.09), impaired balance ability (OR=5.54; 95% CI 3.48 to 8.81), lower mobility (OR=1.12; 95% CI 1.05 to 1.19), history of falls (OR=2.33; 95% CI 1.54 to 3.53) and walking aid (OR=1.98; 95% CI 1.37 to 2.88), anxiety (OR=2.29; 95% CI 1.43 to 3.67), depression (OR=1.80; 95% CI 1.22 to 2.67), poor lower limb motor function (OR=1.14; 95% CI 1.00 to 1.29) and physically inactiveness (OR=2.04; 95% CI 1.01 to 4.12). Measurement of heterogeneity between studies was high for all outcomes (I² =0%-93%), indicating that the substantial interstudy heterogeneity in estimated proportions was not attributed to the sampling error. Sensitivity analysis (leave-one-out method) showed that the pooled estimate was stable.

CONCLUSION

This meta-analysis indicated that female population, impaired balance ability, lower mobility, history of falls and walking aid in patients with stroke might be at greater risk for FoF. Future studies are recommended to determine other risk factors specific to patients with stroke.
