Fear of Falling and postural reactivity in patients with glaucoma
PLOS ONE, 2017Co-Authors: Fabio B Daga, Alberto Dinizfilho, Erwin R Boer, Carolina P B Gracitelli, Felipe A MedeirosAbstract:Purpose To investigate the relationship between postural metrics obtained by dynamic visual stimulation in a virtual reality environment and the presence of Fear of Falling in glaucoma patients. Methods This cross-sectional study included 35 glaucoma patients and 26 controls that underwent evaluation of postural balance by a force platform during presentation of static and dynamic visual stimuli with head-mounted goggles (Oculus Rift). In dynamic condition, a peripheral translational stimulus was used to induce vection and assess postural reactivity. Standard deviations of torque moments (SDTM) were calculated as indicative of postural stability. Fear of Falling was assessed by a standardized questionnaire. The relationship between a summary score of Fear of Falling and postural metrics was investigated using linear regression models, adjusting for potentially confounding factors. Results Subjects with glaucoma reported greater Fear of Falling compared to controls (-0.21 vs. 0.27; P = 0.039). In glaucoma patients, postural metrics during dynamic visual stimulus were more associated with Fear of Falling (R2 = 18.8%; P = 0.001) than static (R2 = 3.0%; P = 0.005) and dark field (R2 = 5.7%; P = 0.007) conditions. In the univariable model, Fear of Falling was not significantly associated with binocular standard perimetry mean sensitivity (P = 0.855). In the multivariable model, each 1 Nm larger SDTM in anteroposterior direction during dynamic stimulus was associated with a worsening of 0.42 units in the Fear of Falling questionnaire score (P = 0.001). Conclusion In glaucoma patients, postural reactivity to a dynamic visual stimulus using a virtual reality environment was more strongly associated with Fear of Falling than visual field testing and traditional balance assessment.

Cost-effectiveness of an intervention to reduce Fear of Falling
International Journal of Technology Assessment in Health Care, 2013Co-Authors: Jolanda C M Van Haastregt, G. A. Rixt Zijlstra, Marike R. C. Hendriks, Mariëlle E. J. B. Goossens, Jacques Th. M. Van Eijk, Gertrudis I J M KempenAbstract:Objectives: The aim of this study was to assess whether a multicomponent cognitive behavioral group intervention is preferable to usual care in terms of (healthcare) costs and effects on Fear of Falling and activity avoidance. Methods: This economic evaluation was embedded in a randomized controlled trial among 540 community-living adults in the Netherlands, aged 70 years and older who reported Fear of Falling and Fear-induced activity avoidance. The participants allocated to the intervention group received a multicomponent cognitive behavioral group intervention consisting of eight weekly sessions and a booster session. The sessions were aimed at instilling realistic views of falls, reducing fall risk, and increasing activity and safe behavior. Participants in the control group received usual care. Cost outcome measures were healthcare costs, and patient and family costs. Clinical outcomes were Fear of Falling and activity avoidance. All outcomes were assessed at baseline and at 2, 8, and 14 months by means of registration forms, self-administered questionnaires, and interviews by telephone. Results: Participants were randomly allocated to intervention (n = 280) and control groups (n = 260). Costs for the intervention program were on average €276 per person. Total costs per person were comparable (€4,925 in intervention group and €4,828 in control group). Furthermore, favorable effects of the program were observed for Fear of Falling and activity avoidance. Conclusions: This study showed that the intervention program is preferable to usual care in terms of costs and effects. The program had comparable costs and significantly reduced Fear of Falling and associated activity avoidance among older community-living persons. Language: en

socio demographic health related and psychosocial correlates of Fear of Falling and avoidance of activity in community living older persons who avoid activity due to Fear of Falling
BMC Public Health, 2009Co-Authors: Gertrudis I J M Kempen, Kim Delbaere, Jolanda C M Van Haastregt, Kevin Mckee, G Rixt A ZijlstraAbstract:Background Fear of Falling and avoidance of activity are common in old age and are suggested to be (public) health problems of equal importance to falls. Earlier studies of correlates of Fear of Falling and avoidance of activity did hardly differentiate between severe and mild levels of Fear of Falling and avoidance of activity which may be relevant from clinical point of view. Furthermore, most studies focused only on socio-demographics and/or health-related variables and hardly incorporated an extensive range of potential correlates of Fear of Falling including psychosocial variables. This study analyzes the univariate and multivariate associations between five socio-demographic, seven health-related and six psychosocial variables and levels of Fear of Falling and avoidance of activity in older persons who avoid activity due to Fear of Falling.

interventions to reduce Fear of Falling in community living older people a systematic review
Journal of the American Geriatrics Society, 2007Co-Authors: G Rixt A Zijlstra, Jolanda C M Van Haastregt, Jacques Th. M. Van Eijk, Erik Van Rossum, Lucy Yardley, Gertrudis I J M KempenAbstract:The objective was to assess which interventions effectively reduce Fear of Falling in community-living older people. An extensive search for relevant literature comprised a database search of PubMed, EMBASE, PsycINFO, and the Cochrane Central Register of Controlled Trials; expert consultation; and manually searching reference lists from potentially relevant papers. Randomized, controlled trials that assessed Fear of Falling in community-living older people were included. Two independent reviewers extracted data from full papers on study characteristics, methodological quality, outcomes, and process characteristics of the intervention. The search identified 599 abstracts, and 19 papers met the inclusion criteria. Seven of those papers were identified using expert consultation. Fifty-five percent of all validity items and 39% of process characteristic items were fulfilled across the 19 trials. Twelve of the 19 papers were of higher methodological quality. In 11 of these trials, Fear of Falling was lower in the intervention group than in the control group. Interventions that showed effectiveness were fall-related multifactorial programs (n=5), tai chi interventions (n=3), exercise interventions (n=2), and a hip protector intervention (n=1). Three of these interventions explicitly aimed to reduce Fear of Falling. Several interventions, including interventions not explicitly aimed at Fear of Falling, resulted in a reduction of Fear of Falling in community-living older people. Limited but fairly consistent findings in trials of higher methodological quality showed that home-based exercise and fall-related multifactorial programs and community-based tai chi delivered in group format have been effective in reducing Fear of Falling in community-living older people.

prevalence and correlates of Fear of Falling and associated avoidance of activity in the general population of community living older people
Age and Ageing, 2007Co-Authors: Jolanda C M Van Haastregt, G Rixt A Zijlstra, Th J M Van Eijk, E Van Rossum, Paul A StalenhoefAbstract:Background: little is known about the prevalence rates and correlates of Fear of Falling and avoidance of activity due to Fear of Falling in the general population of community-living older people. Objective: to assess prevalence rates and study correlates of Fear of Falling and avoidance of activity due to Fear of Falling in this population. Study design and setting: cross-sectional study in 4,031 community-living people aged ≥70 years. Results: Fear of Falling was reported by 54.3% and associated avoidance of activity by 37.9% of our population. Variables independently associated with Fear of Falling were: higher age (≥80 years: odds ratio (OR) = 1.79; 95% confidence interval (CI) = 1.49‐2.16), female gender (OR = 3.23; 95% CI = 2.76‐3.79), poor perceived general health (OR = 6.93; 95% CI = 4.70‐10.21) and multiple falls (OR = 5.72; 95% CI = 4.40‐7.43). Higher age (≥80 years: OR = 1.92; 95% CI = 1.59‐2.32), poor perceived general health (OR = 11.91; 95% CI = 8.38‐16.95) and multiple falls (OR = 4.64; 95% CI = 3.73‐5.76) were also independently associated with avoidance of activity. Conclusions: Fear of Falling and avoidance of activities due to Fear of Falling, were highly prevalent in our sample of community-living older people. Particularly, poor perceived general health showed a strong, independent association with both, Fear of Falling, and related avoidance of activity. Findings of our study may help health care professionals to identify people eligible for interventions aimed at reducing Fear of Falling and activity restriction.
