Patients with chronic kidney disease (CKD) are more likely to experience falls and fractures due to renal osteodystrophy and the high prevalence of risk factors for falls. However, it is not well established how great the risk is for falls and fractures for the different stages of CKD compared to the general population. The objective of this systematic review and meta-analysis was to assess whether, and in which degree, CKD was associated with falls and fractures in adults. A systematic search in PubMed, Embase, CINAHL, and The Cochrane Library was performed on 7 September 2018. All retrospective, cross-sectional, and longitudinal studies of adults (18 years of older) that studied the association between CKD, fractures, and falls were included. Additional studies were identified by cross-referencing. A total of 39 publications were included, of which two publications assessed three types of outcome and four publications assessed two types of outcome. Ten studies focused on accidental falling; seventeen studies focused on hip, femur, and pelvis fractures; seven studies focused on vertebral fractures; and thirteen studies focused on any type of fracture without further specification. Generally, the risk of fractures increased when kidney function worsened, with the highest risks in the patients with stage 5 CKD or dialysis. This effect was most pronounced for hip fractures and any type of fractures. Furthermore, results on the association between CKD and accidental falling were contradictory. Compared to the general population, fractures are highly prevalent in patients with CKD. Besides more awareness of timely fracture risk assessment, there also should be more focus on fall prevention.

BACKGROUND: Falls risk is elevated in chronic obstructive pulmonary disease (COPD). However, there is a lack of evidence regarding the contributing factors. Here, we examined the feasibility of, and initial responses to, large walking perturbations in COPD, as well as the adaptation potential of people with COPD to repeated walking perturbations that might indicate potential for perturbation-based balance training in COPD. METHODS: 12 participants with COPD undergoing inpatient pulmonary rehabilitation and 12 age-gender-matched healthy control participants walked on an instrumented treadmill and experienced repeated treadmill-belt acceleration perturbations (leading to a forward balance loss). Three-dimensional motion capture was used to quantify the stability of participants body position during perturbed walking. Feasibility, stability following the initial perturbations and adaptation to repeated perturbations were assessed. FINDINGS: Using perturbations in this manner was feasible in this population (no harness assists and participants completed the minimum number of perturbations). No clear, specific deficit in reactive walking stability in COPD was found (no significant effects of participant group on stability or recovery step outcomes). There were mixed results for the adaptability outcomes which overall indicated some adaptability to repeated perturbations, but not to the same extent as the healthy control participants. INTERPRETATION: Treadmill-based perturbations during walking are feasible in COPD. COPD does not appear to result in significant deficits in stability following sudden perturbations and patients do demonstrate some adaptability to repeated perturbations. Perturbation-based balance training may be considered for fall prevention in research and practice in people with COPD. ispartof: CLINICAL BIOMECHANICS vol:91 ispartof: location:England status: published

The kyphosis angle of the thoracic spine tends to increase with aging. Hyperkyphosis is a kyphosis angle, exceeding the normal range. This narrative literature review aims to provide an overview of the current literature concerning kyphosis measurement methods, the etiology and adverse health effects of hyperkyphosis. As of yet, a well-defined threshold for hyperkyphosis is lacking. To attain more generalizability and to be able to compare study results in older adults, we propose to define age-related hyperkyphosis as a Cobb angle of 50° or more in standing position. Hyperkyphosis may be a potentially modifiable risk factor for adverse health outcomes, like fall risk and fractures. Additionally, hyperkyphosis may indicate the presence of osteoporosis, which is treatable. Prospective and intervention studies, using a Cobb angle of 50° as a clear and uniform definition of hyperkyphosis, are warranted to investigate the clinical relevance of hyperkyphosis.

In an increasingly economically oriented healthcare system the analysis of disease-specific costs is becoming more and more relevant, especially in chronic diseases with long duration of hospitalization. As a frequent neurodegenerative disease idiopathic Parkinson's disease (IPD) causes high healthcare costs. The pathognomonic affection of mobility and equilibrium often leads to fall-related fractures in the course of the disease, which cause further costs through hospitalization and possibly surgical treatment.The aim of the study was the calculation of inpatient treatment costs of fall-related fractures in IPD as well as the analysis of relevant cost-causing factors. In addition, an alternative calculation of the treatment costs was carried out with the question of potential remuneration problems in the current diagnosis-related groups (DRG) system.The basis of this retrospective, single center analysis was the actual revenue of 95 patients treated between January 2011 and January 2018 at the University Hospital Frankfurt am Main. The proceeds were systematically reviewed for relevant demographic, healthcare and disease-related aspects and statistically analyzed for cost-related factors using univariate analysis. The alternative calculation of the treatment costs was carried out according to commonly used health economics methods.The median revenue per patient and injury was 9295 € (±8038 €, median 7148 €) with a mean length of stay of 13.5 days (±7.2 days, median 13 days). The alternative calculation of treatment costs per patient was an average of 9789 € (±6423 €, median 8906 €). High treatment costs were associated with age75 years (p = 0.028), surgical treatment (p = 0.004), intensive care unit (ICU) stay (p = 0.004), limb fractures (p = 0.028) and an advanced stage of IPD (p = 0.028). Significant differences between actual revenue and calculated costs were found for hospital stays ≥14 days (p = 0.009) and advanced stages of disease (p = 0.036).The costs of care in patients with IPD and fall-related fractures are high and relevant to health economics. In general, remuneration based on the DRG system seems to largely cover the costs; however, compensation problems arise especially for patients with a long duration of hospitalization or advanced IPD.

Purpose: The aim of the current study was to evaluate the association between a decreased estimated glomerular filtration rate (eGFR) and accidental falling in elderly patients who visited the day clinic of the department of geriatric medicine of the University of Medical Center Utrecht (UMCU). Study design: A cross-sectional analysis with people aged ≥ 65 years of the Utrecht Cardiovascular Cohort was performed. Patients were stratified into different stages of kidney disease (< 45, 45–59, and ≥ 60 ml/min per 1.73 m2). Logistic regression models were used to evaluate the association between chronic kidney disease and falling. Results: Our analysis included 1000 participants with a mean age 79.4 (± 6.6) years, of whom 38% had an eGFR of < 60 ml/min per 1.73 m2 and 17% < 45 ml/min per 1.73 m2. Univariate analysis showed a significant higher prevalence [odds ratio 1.75 (95% confidence interval 1.21–2.53; p ≤ 0.01)] of falling in the population with an eGFR < 45 ml/min per 1.73 m2 compared to patients with an eGFR ≥ 60 ml/min per 1.73 m2. After correcting for multiple potential confounders in the multivariate analysis, this association was no longer present. Conclusions: In geriatric patients ≥ 65 years, patients with a decreased eGFR fall more often than patients with a preserved kidney function. This seems to be related with the risk profile of patients with CKD and not with a decreased eGFR itself, as after correcting for potential confounders no association remained. Nevertheless, accidental falling is a highly prevalent problem in the elderly CKD population. Therefore, nephrologists should actively ask about accidental falling, and thereby screen for high-risk patients.

A flexed posture (FP) is characterized by protrusion of the head and an increased thoracic kyphosis (TK), which may be caused by osteoporotic vertebral fractures (VFs). These impairments may affect motor function, and consequently increase the risk of falling and fractures. The aim of the current study was therefore to examine postural control during walking in elderly patients with FP, and to investigate the relationship with geriatric phenomena that may cause FP, such as increased TK, VFs, frailty, polypharmacy and cognitive impairments. Fifty-six elderly patients (aged 80 ± 5.2 years; 70% female) walked 160 m at self-selected speed while trunk accelerations were recorded. Walking speed, mean stride time and coefficient of variation (CV) of stride time were recorded. In addition, postural control during walking was quantified by time-dependent variability measures derived from the theory of stochastic dynamics, indicating smoothness, degree of predictability, and local stability of trunk acceleration patterns. Twenty-five patients (45%) had FP and demonstrated a more variable and less structured gait pattern, and a more irregular trunk acceleration pattern than patients with normal posture. FP was significantly associated with an increased TK, but not with other geriatric phenomena. An increased TK may bring the body's centre of mass forward, which requires correcting responses, and reduces the ability to respond on perturbation, which was reflected by higher variation in the gait pattern in FP-patients. Impairments in postural control during walking are a major risk factor for falling: the results indicate that patients with FP have impaired postural control during walking and might therefore be at increased risk of falling.

Background: Vertebral fractures, an increased thoracic kyphosis and a flexed posture are associated with falls. However, this was not confirmed in prospective studies. We performed a prospective cohort study to investigate the association between vertebral fractures, increased thoracic kyphosis and/or flexed posture with future fall incidents in older adults within the next year.Methods: Patients were recruited at a geriatric outpatient clinic. Vertebral fractures were evaluated on lateral radiographs of the spine with the semi-quantitative method of Genant; the degree of thoracic kyphosis was assessed with the Cobb angle. The occiput-to-wall distance was used to determine a flexed posture. Self-reported falls were prospectively registered by monthly phone contact for the duration of 12 months.Results: Fifty-one older adults were included; mean age was 79 years (SD = 4.8). An increased thoracic kyphosis was independently associated with future falls (OR 2.13; 95% CI 1.10-4.51). Prevalent vertebral fractures had a trend towards significancy (OR 3.67; 95% CI 0.85-15.9). A flexed posture was not significantly associated with future falls.Conclusion: Older adults with an increased thoracic kyphosis are more likely to fall within the next year. We suggest clinical attention for underlying causes. Because patients with increased thoracic curvature of the spine might have underlying osteoporotic vertebral fractures, clinicians should be aware of the risk of a new fracture.

Background: We analysed whether a combination of bone-and fall-related risk factors (RFs) in addition to a recent non-vertebral fracture (NVF) contributed to subsequent NVF risk and mortality during 2-years in patients who were offered fall and fracture prevention according to Dutch fracture-and fall-prevention guidelines.Methods: 834 consecutive patients aged >= 50 years with a recent NVF who were included. We compared subgroups of patients according to the presence of bone RFs and/or fall RFs (group 1: only bone RFs; group 2: combination of bone and fall RFs; group 3: only fall RFs; group 4: no additional RFs). Univariable and multivariable Cox regression analyses were performed adjusted for age, sex and baseline fracture location (major or minor).Results: 57 (6.8%) had a subsequent NVF and 29 (3.5%) died within 2-years. Univariable Cox regression analysis showed that patients with the combination of bone and fall RFs had a 99% higher risk in subsequent fracture risk compared to all others (Hazard Ratio (HR) 1.99; 95% Confidence Interval (CI) 1.18-3.36) Multivariable analyses this was borderline not significant (HR 1.70; 95% CI: 0.99-2.93). No significant differences in mortality were found between the groups.Conclusion: Evaluation of fall RFs contributes to identifying patients with bone RFs at highest immediate risk of subsequent NVF in spite of guideline-based treatment. It should be further studied whether earlier and immediate prevention following a NVF can decrease fracture risk in patients with a combination of bone and fall RFs.

The objective of this work is to determine risk factors for falling in patients with Parkinson's disease (PD) using home-based assessments and develop a prediction model. Data on falls, balance, gait-related activities, and nonmotor symptoms were obtained from 153 PD patients (Hoehn-Yahr 2-4) in their home. Fifty-one candidate determinants for falling were independently tested using bivariate logistic regression analysis. A multivariate logistic regression model was developed to identify patients susceptible to falls. Sixty-six subjects (43%) were classified as fallers. Eighteen determinants for falling were selected. The final multivariate model showed an accuracy of 74% and included: (1) Freezing of Gait Questionnaire, (2) Timed Get Up and Go (TGUG) score, (3) disease duration, (4) item 15 of the Unified Parkinson's Disease Rating Scale. Based on disease duration, freezing symptoms, walking problems, and a prolonged TGUG duration, assessed in the home situation, it was possible to accurately identify 74% of PD patients as fallers. © 2008 Movement Disorder Society.

Background Patients with a history of a fracture have an increased risk for future fractures, even in short term. The aim of this study was to assess the number of patients with falls and to identify fall risk factors that predict the risk of falling in the first three months after a clinical fracture. Methods Prospective observational study with 3 months of follow-up in a large European academic and regional hospital. In 277 consenting women and men aged ≥ 50 years and with no dementia and not receiving treatment for osteoporosis who presented to hospital with a clinical fracture, fall risk factors were assessed according to the guidelines on fall prevention in the Netherlands. Follow-up information on falls and fractures was collected by monthly telephone interview. Incidence of falls and odds ratio's (OR, with 95% confidence intervals) were calculated. Results 512 consecutive patients with a fracture were regarded for analysis, 87 were not eligible for inclusion and 137 patients were excluded. No follow-up data were available for 11 patients. Therefore full analysis was possible in 277 patients. A new fall incident was reported by 42 patients (15%), of whom five had a fracture. Of the 42 fallers, 32 had one new fall and 10 had two or more. Multivariate analysis in the total group with sex, age, ADL difficulties, urine incontinence and polypharmacy showed that sex and ADL were significant fall risk factors. Women had an OR of 3.02 (95% CI 1.13–8.06) and patients with ADL-difficulties had an OR of 2.50 (95% CI 1.27–4.93). Multivariate analysis in the female group with age, ADL difficulties, polypharmacy and presence of orthostatic hypotension indicated that polypharmacy was the predominant risk factor (OR 2.51; 95% CI: 1.19 – 5.28). The incidence of falls was 35% in women with low ADL score and polypharmacy compared to 15% in women without these risk factors (OR 3.56: CI 1.47 – 8.67). Conclusion 15% of patients reported a new fall and 5 patients suffered a new fracture within 3 months. Female sex and low ADL score were the major risk factors and, in addition, polypharmacy in women.

To investigate the risk of being fearful or fearless of falls in older people.Using a force plate, postural control in different sensory and rhythmic conditions was measured in 263 community-dwelling older people. Other assessments included fear of falling, and handgrip strength. Fall incidence was assessed at baseline and during a one-year follow-up period.Logistic regression analysis revealed that increased lateral sway in near-tandem stance with eyes open (OR = 5.33; p0.01) and a worse performance on anteroposterior rhythmic weight shifts (OR = 0.65; p0.05) were related to falls. Univariate analyses revealed that older people with inappropriate high fear of falling according to their fall incidence had worse balance capacities on the rhythmic weight shifts (p0.05) but had similar static balance and physical capacities. Older people with inappropriate low fear of falling had a better hand grip (p0.05) but equally worse balance capacities than the comparison group.The results indicate the importance of lateral stability in relation to falls. They also suggest a substantial impact of inappropriate fear of falling on physical performance. Inappropriate high fear of falling may result in worse performance during dynamic balance tests, whereas older people with inappropriate low fear seem to overrate their capacities because of higher strength.

Objective: To construct a risk model in order to identify elderly individuals at risk of frequent falling. Design: Prospective community-based cohort study over 12 months. Setting: Baseline measures were performed at a local community centre. Subjects: Two hundred and sixty-three community-dwelling elderly people (mean age 72 years). Measurements: A variety of variables were evaluated, including medical, psychological, sensory, physical and postural control measurements. Fall incidence was monitored retrospectively and during one-year follow-up. Results: Logistic regression analysis showed that polypharmacia was the most prominent medical fall predictor with an odds ratio (OR) of 1.29 (P =0.005), poor visual acuity the best sensory predictor (OR=0.84; P =0.009) and general fear of falling the most crucial psychological predictor (OR=3.25; P B=0.001). Increased postural sway in near-tandem stance with eyes open was selected as the best balance predictor for falls (OR=5.60; P =0.010), followed by delayed anteroposterior movement velocity during rhythmic weight shifts (OR=0.42; P =0.004). The best physical predictor was a low score on the Physical Performance Test (OR=4.16; P Conclusion: This study confirms the multicausality of falls, since medical, psychological, sensory, postural control as well as physical variables provides a predictive value. The composed fall risk model was mainly physically oriented.

Objective: to investigate the relationship between fear-related avoidance of activities and physical frailty. Subjects and methods: fear-related avoidance of activities, physical performance, maximal isometric muscle strength and postural control were assessed in 225 community-living elderly (94 men and 131 women), aged between 61 and 92 years of age. Results: bivariate analyses revealed significant correlations between avoidance of activities on the one hand, and physical performance, muscle strength, forward endpoint excursion of the centre of gravity, and previous falls on the other hand. Logistic regression analysis revealed that fear of falling and avoidance of activities in daily life were predictive of falls within a 1-year follow-up, together with general fear of falling, old age and being female. Conclusions: fear-related avoidance of activities may have negative effects on physical abilities and may also be predictive for future falls. Avoidance of activities is therefore an important additional psychological variable in the development of physical frailty and falling in community-living elderly.

Fifty female subjects, aged 72-92 (mean 82) years, were enrolled in a 12-week (36 classes) exercise program aimed at increasing postural stability. Subjects were residents of sheltered apartments, rest homes or nursing homes, well enough and mobile enough to participate in the classes. The subjects were randomized into an exercise or a control group. Their postural sway, standing at rest on a force platform, was measured with eyes open and eyes closed. The groups were well matched in all respects. The results showed no improvement in the postural sway as a result of the exercise program. We hypothesize that increasing postural sway in the elderly represents a deterioration in, for the most part, the nervous system and may at this extreme of life indicate an irreversible loss of function. For this reason no improvement in postural sway may be possible.

To investigate the efficacy of a guided and graded home-based exercise program for improving a range of physical outcomes in older people.Controlled clinical trial of 16 weeks.Two geographical areas in Gent, Belgium.66 independent-living older people (age: 71-98) with a history of falls and moderate physical impairment.Twenty-four 30-minute training sessions were given by a trained physiotherapist over a period of 16 weeks in the participant's home. Different types of exercises on balance, aerobic performance, flexibility, and muscle strength were provided.Muscle strength, static and dynamic balance, aerobic performance, activities in daily living, fear of falling and avoidance of daily activities were assessed at baseline and after 16 weeks intervention.At baseline, there were no significant differences in the measured variables between exercise and control groups. After 16 weeks, the exercise group showed significantly improved ankle muscle strength, balance performance and aerobic capacity, and decreased fear of falling, dependency in daily activities and avoidance of daily activities compared to the control group. The improvements in knee muscle strength, timed chair stands, and functional reach were not significant.The home-based, individualized exercise program was effective in reducing several physical factors associated with falls in community-dwelling older people with moderate physical impairment. The decrease in fear of falling and other behavioural variables needs to be considered with care and needs further investigation.
