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.

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.

Fear of falling and related factors during everyday activities in patients with chronic stroke

The aim of this study was to examine the impact of physical function, anxiety, and depression on the fear of falling associated with everyday activities in patients with stroke. This was a cross-sectional descriptive survey. Convenience sampling was used to select 127 patients with stroke who were undergoing rehabilitative therapy at a single rehabilitation hospital in South Korea. Fear of falling, anxiety, and depression were assessed using structured questionnaires. Physical parameters, including lower extremity function, functional mobility, balance ability, and lower extremity muscle strength, were measured using objective methods. A multiple regression analysis was used to identify the predictors of fear of falling. Female patients had a higher fear of falling associated with walking outdoors compared to male patients. Lower extremity strength was the only significant predictor of fear of falling when adjusting for age, sex, Mini Mental State Examination scores, and fall experience. Lower extremity strength was identified as the most important factor affecting the fear of falling associated with everyday activities in patients with stroke. Preventing muscle weakness in the lower extremities and providing education and support to improve patients' self-efficacy in outdoor activities are strategies that can be used to reduce the fear of falling in patients with stroke.

Fear of Falling and Related Factors in Older Adults With Spinal Diseases

Fear of falling is common among older adults with spinal diseases. The purpose of the current study was to examine fear of falling and related factors in this population. A total of 138 participants were recruited and completed survey questionnaires along with the Timed Up & Go Test. Participants were 73.7 years old on average, 52% had fall experience, and 56% were taking more than four medications. Multivariate regression analyses revealed that the use of sleeping pills, residence type, pain, activities of daily living, gait ability, and gait efficacy were significant predictors of fear of falling. Findings suggest that a fall prevention intervention for older adults with spinal diseases should include pain management, functional improvement, and gait rehabilitation with a focus on gait performance and gait efficacy. In addition, it is important to improve living environment and sleep hygiene, which are conducive to falls. [Journal of Gerontological Nursing, 47(8), 29-35.].

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

The early identification of individuals at risk of fear of falling after stroke is crucial in order to individualise preventive actions and interventions. The aim of this study was to identify the incidence of, and baseline factors in acute stroke that are associated with fear of falling at 6 months after stroke. Fear of falling was assessed by one question, which was answered by 279 of 452 eligible individuals. Univariable and multivariable logistic regression analyses were performed to determine the factors that were associated with fear of falling. The dependent variable was fear of falling at 6 months after stroke. The independent variables were related to function, activity and participation, including personal and environmental factors. Fear of falling was reported by 117 (41.9%) individuals. Poor postural control in acute stroke, measured using the modified version of the Postural Assessment Scale for Stroke Patients (odds ratio [OR]: 2.60, 95% confidence interval [CI]: 1.26–5.36), and being physically inactive prior to the stroke, measured using the Saltin-Grimby Physical Activity Scale (OR: 2.04, 95% CI: 1.01–4.12), were found to be associated with fear of falling at 6 months after stroke. The findings in this study are useful in clinical practice to optimise rehabilitation after stroke.

Health anxiety and illness-related fears across diverse chronic illnesses: A systematic review on conceptualization, measurement, prevalence, course, and correlates

BACKGROUND

Patients with chronic diseases commonly report fears of illness or symptoms recurring or worsening. These fears have been addressed from an illness-specific perspective (e.g., fear of cancer recurrence), a generic illness perspective (e.g., fear of progression), and a psychiatric perspective (DSM-5 illness anxiety disorder and somatic symptom disorder). The broader concept of health anxiety (HA) can also be applied to patients with a chronic disease. This review was conducted to investigate the conceptual, theoretical, measurement-overlap, and differences between these distinct perspectives. We also aimed to summarize prevalence, course, and correlates of these fears in different chronic illnesses.

METHODS

We used PsycINFO, PubMED, CINAHL, Web of Science, SCOPUS, and PSYNDEX to conduct a systematic review of studies pertaining to these fears in chronic illness published from January 1996 to October 2017. A total of 401 articles were retained.

RESULTS

There were commonalities across different conceptualizations and diseases: a high prevalence of clinical levels of fears (>20%), a stable course over time, and a deleterious impact on quality of life. Reviewed studies used definitions, models, and measures that were illness-specific, with only a minority employing a psychiatric perspective, limiting cross-disease generalizability. There appears to be some applicability of DSM-5 disorders to the experience of fear of illness/symptoms in patients with a chronic illness. While conceptualizing HA on a continuum ranging from mild and transient to severe may be appropriate, there is a lack of agreement about when the level of fear becomes 'excessive.' The definitions, models, and measures of HA across chronic illnesses involve affective, cognitive, behavioral, and perceptual features.

CONCLUSIONS

The concept of HA may offer a unifying conceptual perspective on the fears of illness/symptoms worsening or returning commonly experienced by those with chronic disease.

Factors affecting fear of falls in patients with chronic stroke

Objective: The aim of this study was to find the factors associated with fear of falls in patients having chronic stroke.Methods: Inclusion criterion was subjects with cerebral stroke for more than 3 months. A structured interview of 82 subjects was conducted with a questionnaire with questions regarding personal factors such as gender, side affected, number of comorbidities, and setting of physical therapy sessions. Depression was assessed using Patient Health Questionnaire-9, lower extremity motor function was assessed using Fugl-Meyer scale, and functional mobility was assessed using Timed Up and Go. Chi-square analysis was done on the above factors to find significant factors followed by logistic regression of the factors found significant in Chi square.Results: Lower extremity Fugl-Meyer score was significantly associated with fear of falls (p value 0.047 with Odds ratio of 1.136, 95% CI 1.002-1.287) in patients having chronic stroke while treatment factors, such as setting of physical therapy sessions, and personal factors, such as gender, side affected, number of comorbidities, depression, functional mobility, or use of walking aid, were not found to have significant association.Conclusion: The lower extremity Fugl-Meyer score is associated with fear of falls in patients having chronic stroke.

The Crucial Changes of Sit-to-Stand Phases in Subacute Stroke Survivors Identified by Movement Decomposition Analysis

Objective

The aim of this study was to detect the key changes during sit-to-stand (STS) movement cycle in hemiparetic stroke survivors using a five-phase kinematic and kinetic analysis.

Methods

Twenty-five subacute stroke survivors and 17 age-matched healthy adults participated in this study. The kinematic and kinetic parameters during STS cycle were measured using three-dimensional motion analysis system with force plates. The five standard phases of STS cycle were identified by six timing transitional points.

Results

Longer total time as well as larger changes were observed at the initial phase (phase I, 0.76 ± 0.62 VS 0.43 ± 0.09 s; p = 0.049) and at the end of hip and knee extension phase (phase IV, 0.93 ± 0.41 VS 0.63 ± 0.14 s; p = 0.008) in the stroke group than healthy group. Time to maximal knee joint moment was significantly delayed in the stroke group than in the control group (1.14 ± 1.06 VS 0.60 ± 0.09 s, p < 0.001). The maximal hip flexion was lower during the rising phase from seated position on the affected side in the stroke group than in the control group (84.22° ± 11.64°VS 94.11° ± 9.40°; p = 0.022). Ground reaction force was lower (4.61 ± 0.73 VS 5.85 ± 0.53 N, p < 0.001) in the affected side of the stroke group than in the control group. In addition, knee joint flexion was significantly lower at just-standing phase (T₄) and at end point (T₅) (5.12° ± 5.25° VS 8.21° ± 7.28°, p = 0.039; 0.03° ± 5.41° VS 3.07° ± 6.71°, p = 0.042) on the affected side than the unaffected side. Crucial decrease of knee joint moment at abrupt transitory (T₂) and the maximal moment was also observed on the affected side in comparison with the unaffected side (0.39 ± 0.29 VS 0.77 ± 0.25 Nm/kg, p < 0.001; 0.42 ± 0.38 VS 0.82 ± 0.24 Nm/kg, p < 0.001).

Conclusion

The findings of movement decomposition analysis provided useful information to clinical evaluation of STS performance, and may potentially contribute to the design of rehabilitation intervention program for optimum functional recovery of STS after stroke.
