Being unable to “get up from the floor” is a risk factor and predictor of serious fall-related injuries in older age; however, floor-rise training (FRT) is not widely used. The backward chaining method (BCM) is a success-oriented, step-by-step form of FRT. This systematic review aimed to evaluate the impact of BCM on physical and psychological outcome measures, and its clinical application. Studies were identified through systematic searching of five databases. Criteria for inclusion were: use of BCM as a treatment method, outcome measures related to falls, and participants aged 60 + years. Study quality was evaluated using the Mixed Methods Appraisal Tool and PEDro scale, if applicable. Seven studies with a total of 446 participants (mean age 82.4 ± 5.3 years) were identified. Emerging evidence shows that BCM significantly improves the ability to get up unassisted from the floor, as well as mobility with reduced fall incidence in older people. Furthermore, it can potentially reduce fear of falling. Reporting on feasibility and acceptance of BCM was limited. Study quality varied widely. BCM provides a promising intervention in fall-related recovery strategies for older adults and is most effective when offered to older adults at risk of falling. Considering the small number of included studies and the varying methodological quality, these findings should be evaluated accordingly. The growing evidence regarding the benefits of BCM, yet the lack of adoption into standard care, highlights the need for further research and clinical application of this intervention approach.

Half of the people with fear of falling (FoF) are non-fallers, and the reason why some people considered non-fallers are afraid of falling is unknown, but reduced mobility or cognition, or both concurrently must be considered as potential risk factors. The study aimed to determine if mobility and/or cognitive abilities could identify people with a history of falls in older adults with FoF. Twenty-six older adults with FoF participated in this study. Full cognitive and mobility assessments were performed assessing global cognitive impairments (MoCA score 13.5 s), gait, balance and physical capacity. Information about falls occurring during the year prior to the inclusion was collected. Logistic regression analyses were performed to explore the association between falls and cognitive and mobility abilities. No significant differences in age, sex, level of education or body mass index were detected between fallers and non-fallers. Cognitive impairments (MoCA score 13.5 s), gait, balance and physical capacity were not related to past falls. In older adults with FoF, global cognitive deficits detected by the MoCA are important factors related to falls and more particularly visuospatial skills seem to be among the most implicated functions. These functions could be targeted in multifactorial interventions.

This study was aimed to compare early-stage Alzheimer's disease (AD) and dementia with Lewy bodies (DLB), the two most common types of dementia in the elderly, in terms of the prevalence of geriatric syndromes. Patients with early-stage dementia with DLB and AD were included, and were questioned in terms of geriatric syndromes including polypharmacy, malnutrition, frailty, sarcopenia, dynapenia, orthostatic hypotension (OH), urinary and fecal incontinence, falls, fear of falling (FoF), depression, insomnia, excessive daytime sleepiness, pressure ulcers. Of the 82 patients, 31 had DLB and 51 had AD. The mean age was 80.99 +/- 7.01, and 69.5% was female. The presence of OH, FoF, depression, and insomnia were more common in the DLB than AD (p < 0.05). 90.3% of patients with DLB and 54.9% of patients with AD had >= 3 geriatric syndromes simultaneously. The presence and co-incidence of geriatric syndromes is common in patients with even early-stage DLB and AD.

BackgroundFear of falling is highly prevalent in older adults and associated with numerous negative health events. The main objective of this study was to validate a scale to assess fear of falling, based on performance in real situation (Perform-FES), in a hospitalized geriatric population.MethodsIn this cross-sectional study, 55 patients (mean age: 85.3 years; 58% women) hospitalized in a geriatric hospital in Geneva (Switzerland) were enrolled. The Perform-FES scale was administered to all patients in conjunction with four other fear of falling scales. We determined the floor and ceiling effects, internal consistency, reliability, construct validity, and discriminative power of the Perform-FES scale.ResultsThe Perform-FES scale did not demonstrate any significant floor or ceiling effect. It had a good internal consistency (Cronbach’s alpha = 0.78) and an excellent reliability (intraclass correlation coefficient = 0.94). Regarding convergent validity, good correlations were shown between the score obtained on the Perform-FES scale and those obtained on other fear of falling scales. Also, the Perform-FES scale was able to discriminate patients with severe functional impairments (area under the ROC curve = 0.81) and had significantly better discriminating performance than other fear of falling scales.ConclusionFindings suggest that the Perform-FES scale has good psychometric properties and may be a relevant tool to assess fear of falling in a geriatric hospitalized population. Future research should focus in particular on assessing the sensitivity to change and the predictive value of this scale in longitudinal studies, and its validity in other populations.

Fear of falling (FoF) is a common psychological problem in community-dwelling older adults. However, which mobility function relate to newly developed FoF and persistent FoF are unknown. We aimed to clarify which baseline mobility function is an independent predictor of one-year change in FoF. The study design was a one-year longitudinal predictive validity study. Participants were 581 independently community-dwelling older adults without neurological disorders. We measured FoF, history of falls, inactive lifestyle, and sociodemographic data were obtained via a self-administered questionnaire. Mobility functions were measured by community-based Short Physical Performance Battery (SPPB-com). Newly developed FoF group accounted for 20% among the non-FoF older adults at baseline. Persistent FoF group accounted for 57% among the older adults with FoF at baseline. Risk of newly developed FoF was significantly related to the SPPB-com total score, among the mobility functions, the low gait test score (OR [95% CI] = 2.34 [1.12–5.12]) and the low tandem balance test score (OR [95% CI] = 3.62 [1.46–8.90]) were significantly related. Risk of persistent FoF was also related to SPPB-com total score, among the mobility functions, the five chair stand test score (OR [95% CI] = 1.96 [1.19–3.24]) was significantly related. The risk of newly developed FoF related to lower ability of standing-balance and gait, the risk of persistent FoF related to lower sit-to-stand ability. Appropriate exercise interventions according to FoF subtype may effectively prevent the risk of developing FoF or experiencing persistent FoF.

The aim of this study was to determine the relationship between the fear of falling/the degree of fear of falling (FoF) and orthostatic hypotension (OH) in older adults. This cross-sectional study was conducted with 314 older outpatients. If the total score of the Falls Efficacy Scale-International scale was 16-19, 20-27 and >= 28, it was assumed that there was low FoF, moderate FoF and high FoF, respectively. OH was evaluated for the 1st (OH1) and 3rd (OH3) minutes, after transitioning from the supine position to standing. Participants were aged 65-93 years (mean age 74.2 +/- 8.5 years) and 193 (61.5%) were female. Among the FoF groups, significant differences were found for age, gender, education, marital status, who the patient lived with, the history of falling and hypertension, Timed Up-Go test score and hemoglobin levels (p < 0.005). The prevalence of OH1 and OH3 was found to be significantly higher in those with an FoF score of 20 and above than those below 20 (p < 0.005). After adjustment for potential confounders, participants who reported a high FoF had higher risk for OH1 and OH3 (OR 2.14, 95% CI 1.14-4.0, p = 0.017; and OR 2.72, 95% CI 1.46-5.09, p = 0.002, respectively), but those with moderate FoF had no increased risk of having OH compared to low FoF (p > 0.05). There is a close relationship between high FoF and OH in older adults. Therefore, when evaluating an older patient with OH, FoF should be evaluated, or FoF should also be questioned in older patients with OH.

Knee osteoarthritis (OA) and fear of falling (FoF) are important factors contributing to trunk oscillation during walking. It is of a clinical importance to clarify the association of FoF with trunk oscillation during walking in older adults with knee OA (knee OA adults). The purpose of this study was to investigate the association of FoF with trunk oscillation during walking in knee OA adults. Forty-one patients who met the criteria participated in the study and were classified into two groups based on their answer to a question on FoF. An accelerometer was attached at the level of the third lumbar vertebra (L3) and the seventh cervical vertebra (C7), and the accelerations at L3 and C7 were measured during a 10-m gait test. Using these data, the acceleration-derived gait indices, such as stride time variability (STV), root mean square (RMS), and autocorrelation at the trunk in the anteroposterior (AP) and mediolateral (ML) directions, were computed. FoF was associated with a higher STV value and a smaller RMS value in the ML direction at L3. The decreased trunk oscillation in the ML direction in knee OA adults with FoF may reflect a positive, compensatory adaptation for trunk control. Knee OA adults with FoF decreased trunk oscillation during walking than those without FoF.

BACKGROUND: Chronic pain is associated with poorer cognition and mobility, and fall risk in older adults. AIMS: To investigate the feasibility of a randomized trial of mind-body exercise (Tai Chi) versus light physical exercise in older adults with multisite pain. METHODS: Adults aged ≥ 65y with multisite pain who reported falling in the past year or current use of an assistive device were recruited from Boston area communities. Participants were randomized to either a Tai Chi or a light physical exercise program, offered twice weekly for 12 weeks. The primary outcomes were feasibility and acceptability. Secondary outcomes included pain characteristics, cognition, physical function, gait mobility, fear of falling, and fall frequency. RESULTS: Of 176 adults screened, 85 were eligible, and 54 consented and enrolled (average age 75±8y; 96.30% white; 75.93% female). The dropout rate was 18% for Tai Chi and 12% for light physical exercise. For those completing the study, exercise class attendance was 76% for Tai Chi and 82% for light physical exercise. There were no significant group differences in most secondary outcomes. Tai Chi significantly lowered pain severity (4.58±1.73 to 3.73±1.79, p

Background Fall-related concern strongly correlates to activity avoidance in older people. In this complex phenomenon, different terminology and instruments are often used interchangeably. Three main concepts make up fall-related concerns: fear of falling, consequence concern, and falls self-efficacy. It is suggested that fall-related concerns are mediated by psychological and physical factors. Aims Our aims were to describe the prevalence of fall-related concerns and find explanatory factors for its most studied concept—falls self-efficacy—in an older population. Methods We executed a cross-sectional study on a random sample of 153 community-dwelling older people (70 years or older). We used validated and reliable instruments as well as structured interviews to gather data on the three concepts of fall-related concerns and possible mediating factors. We then calculated descriptive statistics on prevalence and regression models for the total group, and men and women, separately. Results 70% of the total sample (80% of women and 53% of men) reported at least one of the three concepts of fall-related concern. For the total sample, fear of falling, morale, and physical performance were associated factors with falls self-efficacy. For women, the number of prescription medications was added. For men, physical performance and concerns for injury were associated. Conclusion Fall-related concern is prevalent in large proportions with higher prevalence for women than for men. Important factors are fear of falling, morale, and physical performance. Gender differences in the emergence and variance of fall-related concern and the relation between physical performance and fall-related concern should be targeted in future research endeavors.

The imperative action of the geriatric medicine is to prevent disability in older persons. Many epidemiological studies have been conducted in the last decades for improving knowledge of the aging process and their interactions with age-related diseases, especially for the identification of the relationship between sarcopenia and loss of mobility. Factors influencing muscle integrity can be classified into six main physiologic subsystems, but the central nervous system certainly plays a crucial role for maintaining muscle integrity in older persons. Recent data show that the reduced muscle strength and not muscle mass could be considered the core of the fragility in predicting changes of gait velocity and mobility and conferring a higher risk of mortality in older persons. Sarcopenia and cognitive decline could, therefore, produce slow gait velocity in older persons, with devastating effect and consequences. Perhaps the most notorious corollary is falling, which is often caused by an underlying gait problem. Injuries caused by accidental falls range from relatively innocent bruises to major fractures or head trauma. Another important consequence is reduced mobility, which leads to loss of independence. This immobility is often compounded by a fear of falling, which further immobilises patients and affects their quality of life and physical performance. When we search the association between brain pathology and muscle function in older persons, we amazingly find that established composite measure of physical frailty is associated with brain pathology. Sarcopenia, which produces muscle dysfunction, slow gait velocity and cognitive decline, could share a strong bidirectional relationship, and this suggests the coexistence of both cognitive and motor dysfunctions in older persons to characterize a new syndrome characterized by slow gait and cognitive complaints, the motoric-cognitive risk syndrome (MRC). In this review, we want to emphasize the relationship between memory complaints with muscle function integrating cognitive and physical evaluation, even with amyloid PET study, to identify older patients at high risk of cognitive and physical decline.

BackgroundDizziness is common among older people and falling is a feared complication.AimThe purpose of this study was to investigate the presence of dizziness and its association with falls, walking speed and fear of falling, including sex differences, among 79-year-olds. Secondary purposes were to describe the relationship between dizziness and falls to number of medications and diseases.MethodThe study consisted of the fifth cohort of Gothenburg’s H70 birth cohort studies. A sample of 662 79-year-olds (404 women, 258 men) were investigated with questions regarding dizziness, previous falls and falls efficacy [estimated according to the falls efficacy scale Swedish version (FES (S))]. Functional tests included self-selected and maximal walking speed over 20 m.ResultsDizziness was reported among 51% of the women and by 58% of the men (p = 0.12). Approximately, 40% had fallen during the past 12 months (41% women, 38% of the men,p = 0.48). Dizziness was related to a higher risk of falls among women (OR 2.63 (95% CI 1.67−4.14,p p = 0.8). Dizzy individuals had lower scores on FES (S) (p p p p ConclusionWomen with dizziness more often reported falls compared to women without dizziness—a trend that was not seen among men. Persons with dizziness walked slower. Many medications increased risk of falling; hence, number of medications alone might help pinpoint risk groups for falling.

Movement incoordination, freezing of gait, fear of falling, low self-efficacy, and multi-tasking can all contribute to falls in Parkinson’s disease. How these multi-factorial risks interact in individual patients remain poorly understood. Concurrent arm swing-stepping is a simple motor test in which subjects are first asked to swing their arms before being instructed to initiate the secondary task of leg stepping-in-place. We postulated that in patients with multiple fall risks, sensorimotor impairments in upper- and lower-limb movement control can render concurrent arm swing-stepping a demanding dual task, thereby triggering gait hesitation. A total of 31 subjects with Parkinson’s disease were enrolled in the study. It was found that concurrent arm swing-stepping induced hesitation primarily in Parkinson’s disease patients with low fall-related self-efficacy and a fear of falling. By contrast, concurrent arm swing-stepping led to limb incoordination in both patients and in healthy elderly controls. The calculated specificity and sensitivity of the concurrent arm swing-stepping test was 100 and 42 % for hesitation and 12 and 77 % for incoordination. These results suggest that the concurrent arm swing-stepping test can be used in conjunction with conventional psychometric assessments to facilitate multi-factorial assessment of potential fall risk.

Regression tree (RT) analyses are particularly adapted to explore the risk of recurrent falling according to various combinations of fall risk factors compared to logistic regression models. The aims of this study were (1) to determine which combinations of fall risk factors were associated with the occurrence of recurrent falls in older community-dwellers, and (2) to compare the efficacy of RT and multiple logistic regression model for the identification of recurrent falls. A total of 1,760 community-dwelling volunteers (mean age ± standard deviation, 71.0 ± 5.1 years; 49.4 % female) were recruited prospectively in this cross-sectional study. Age, gender, polypharmacy, use of psychoactive drugs, fear of falling (FOF), cognitive disorders and sad mood were recorded. In addition, the history of falls within the past year was recorded using a standardized questionnaire. Among 1,760 participants, 19.7 % (n = 346) were recurrent fallers. The RT identified 14 nodes groups and 8 end nodes with FOF as the first major split. Among participants with FOF, those who had sad mood and polypharmacy formed the end node with the greatest OR for recurrent falls (OR = 6.06 with p

Vision is an important prerequisite for balance control and mobility. The role of objectively measured visual functions has been previously studied but less is known about associations of functional vision, that refers to self-perceived vision-based ability to perform daily activities. The aim of the study was to investigate the relationship between functional vision and balance and mobility performance in a community-based sample of older adults. This study is part of a Geriatric Multidisciplinary Strategy for the Good Care of the Elderly project (GeMS). Participants (576) aged 76–100 years (mean age 81 years, 70 % women) were interviewed using a seven-item functional vision questionnaire (VF-7). Balance and mobility were measured by the Berg balance scale (BBS), timed up and go (TUG), chair stand test, and maximal walking speed. In addition, self-reported fear of falling, depressive symptoms (15-item Geriatric Depression Scale), cognition (Mini-Mental State Examination) and physical activity (Grimby) were assessed. In the analysis, participants were classified into poor, moderate, or good functional vision groups. The poor functional vision group (n = 95) had more comorbidities, depressed mood, cognition decline, fear of falling, and reduced physical activity compared to participants with moderate (n = 222) or good functional vision (n = 259). Participants with poor functional vision performed worse on all balance and mobility tests. After adjusting for gender, age, chronic conditions, and cognition, the linearity remained statistically significant between functional vision and BBS (p = 0.013), TUG (p = 0.010), and maximal walking speed (p = 0.008), but not between functional vision and chair stand (p = 0.069). Poor functional vision is related to weaker balance and mobility performance in community-dwelling older adults. This highlights the importance of widespread assessment of health, including functional vision, to prevent balance impairment and maintain independent mobility among older population.

Physical frailty has been regarded as a precursor state to disability and dependence on others for daily activities. Frail individuals are considered to be the group of patients that presents the most complex and challenging problems to health care professionals. The purpose of this study was to evaluate whether a 12-week functional circuit training program (FCT) could reduce self-reported fear of falling and improve health status in a group of physically frail community-dwelling older individuals. Fifty-one individuals (31 F, 20 M), mean age (SD) 84 (2.9) years old, were considered frail and tested at week 0 and randomly assigned into two groups (intervention group, FCT = 26; control group, CG = 25). FCT underwent a structured 12-week FCT program, which focused on a combination of functional balance and lower-body strength-based exercises. CG met once a week for health education meetings. Measures of self-reported fear of falling (Activities-specific Balance Confidence scale) and health status (SF-12) were assessed at week 0, 12 and 36. All longitudinal analyses for continuous variables that were measured at the three time points (week 0, 12 and 36) were performed using linear mixed modeling. FCT participants had greater improvements than those in the CG in fear of falling and self-reported physical function, physical composite score and mental composite score; these improvements were maintained in the week 36 follow-up, with significant group-by-time interactions by the end of the study. These data indicate that a FCT program is effective in improving self-reported measures of fear of falling and health status in a group of physically frail individuals.

Background and aims: Depression and fear of falling are common problems following proximal femoral fracture. The role of fear of falling in depressive symptoms after such a fracture has not yet been investigated. The aim of this study was to establish possible changes during recovery in fear of falling and depressive symptoms following rehabilitation in this population and to explore their association. Methods: Observational study with pre-post design at a single geriatric rehabilitation hospital in Germany. Data were collected during in-hospital rehabilitation and four months later at participants' home. The data of 51 participants living in the community at the time of fracture could be analysed. Main measures: Fear of falling, depressive symptoms, cognition, pain, ADL functioning, and physical performance. Results: Although physical and ADL performance improved between admission to rehabilitation and follow-up four months later, the prevalence of depressive symptoms increased, and levels of fear of falling remained at the same level. There was a significant correlation between fear of falling and depressive symptoms at follow-up, but the two were not significantly correlated at baseline. Fear of falling and depressive symptoms were not significantly associated in a path analysis model. Conclusions: Fear of falling and depressive symptoms are highly prevalent after proximal femoral fracture. Yet there seems to be no simple association between either psychological parameter in older persons recovering from fall-related fractures. Further research is warranted, in order to develop interventions targeting these psychological outcomes.

Background and aims: Falls among older people are associated with injury, functional decline, fear of falling, and depression. This study aims to evaluate the effect of multifactorial fall prevention on function, fear of falling, health-related qualify of life and psychological well-being. Methods: 392 older people ≥65 years sustaining a fall, leading to treatment in the emergency room or hospitalization, were included in a randomized, controlled intervention study on multifactorial fall prevention. The intervention consisted of systematic assessment and personalized treatment aimed at reducing risk factors for falls, and was performed at the geriatric outpatient department of a university hospital. The control group received usual care. Outcome measures were functional ability (Barthel Index and Frenchay Activity Index), fear of falling (Activities Balance Confidence Scale), health-related quality of life (SF-36), and psychological well-being (SCL-92), and were recorded at interviews 6 and 12 months after inclusion. Results: Only the physical function of SF-36 was slightly positively affected by the intervention (p=0.04). There were no effects on general health (p=0.49) or mental health (p=0.39) items, Barthel Index (p=0.10), Frenchay Activity Index (p=0.71), balance confidence (p=0.77), anxiety (p=0.92), depression (p=0.90) or somatization (p=0.13). Conclusions: This program of multifactorial fall prevention may have an effect on the physical function item of health-related quality of life in favor of the intervention group, but none on other measures of health-related quality of life, daily function, fear of falling or psychological well-being.

Background and aims: Feasible and low-cost exercise programmes targeting fall risk factors may decrease the risk of falling in older adults. The purpose of this study was to compare the effects of square-stepping exercise (SSE) training, which is a new and low-cost method designed to improve lower-extremity functional fitness, with strength and balance (SB) training. Methods: The study included 39 community-dwelling adults aged 65 to 74 years. The participants were randomized to either group SSE (n=20) or SB (n=19). They engaged in 70-min group exercise sessions twice a week for 12 weeks. The efficacy of the program was measured with both a 9-item test battery for assessment of physical performance and self-reported scales (fear of falling, pleasure in exercise, perceived health status). Fall incidence was followed up for 14 months. Results: The results of a 2-way ANOVA revealed that the time effect in 7 of the 9 performance tests was significant, although group-by-time interactions were not. No significant changes were observed in the self-reported scales. During the 14-month follow-up period, 7 falls in 6 participants in the SSE group and 12 falls in 11 participants in the SB group were reported. The incidence rate per person in the SSE group (30.0%) was not significantly different from that in the SB group (57.9%). The rate of falls per trip [falls/(falls + trips)] in the SSE group (17.1 %) was significantly lower than in the SB group (50.0%). Conclusions: SSE is as equally effective as SB training in improving lower-extremity functional fitness. SSE may also be recommended for older adults, due to its low cost and effectiveness.

Falls in older people commonly cause morbidity and mortality, loss of independence, and poor quality of life. Differences in residential environments might influence falls experienced by elderly people in urban and rural areas. The purpose of this study was to provide data through the comparative analysis of physical and environmental factors influencing falls in the frail elderly individuals in urban and rural areas, which might be used for developing the fall prevention program. A total of 534 frail elderly individuals living in regional communities were assessed over 2 months. Discomfort when walking, avoiding falls, awareness of falls, physical activity, fear of falling, depression, and a safety score for the home environment were measured. Frail elderly individuals in urban and rural areas had significant differences in terms of their prior experience of falls; the number of falls; the intake of hypertension medication, arthritis medication, and painkillers, respectively, discomfort when walking; physical activity; and the safety score of their home environments. There were significant differences between the frail elderly individuals living in urban and rural areas with the highest incidence of falls with regard to their education level, marital status, residential types, the intake of arthritis medication and painkillers, walking discomfort, physical activity, and the safety score of their home environments. In the factors influencing falls of frail elderly individuals in urban areas, stroke, visual impairment, and the fear of falling were significant explanatory variables. In the factors influencing falls of frail elderly individuals in rural areas, dizziness, walking discomfort and the fear of falling were significant explanatory variables. These results indicate that different factors influence falls among the elderly living in different residential areas. Based on these results, a multidimensional customized fall prevention program should be considered by various factors according to residential environments to effectively prevent falls among elderly adults.

Background and aims: Polio survivors are ageing, and reporting new complications including falls. The aims of this study were: 1) to determine the frequency of falls, circumstances surrounding them, and the consequences of falls in older people who have polio; and 2) to investigate the range of fall prevention interventions undertaken to reduce the individual’s risk of falling. Methods: A survey was conducted of members of the Eastern Polio Support Group of Victoria. Twentyeight respondents (70%; 7 male, 21 female) had a mean age of 66 years and an average duration of 57 years since the onset of polio. The survey addressed demographic data, mobility, frequency and description of falls over the last 12 months, their consequences, and community services utilized. The Modified Falls Efficacy Scale (MFES) and Human Activity Profile (HAP) were also completed. Comparative data on the MFES and HAP were obtained from age- and gender-matched healthy community-dwelling older people. Results: Fourteen respondents (50%) reported one or more falls over the past 12 months, half reporting multiple falls. Twothirds of falls occurred while walking. Of those who fell, 67% did not require medical attention. The highest percentage of injuries were bruises or grazes (44%), with one fracture reported. Sixty-one percent reported being fearful of falling, with an average MFES of 7.4 (±2.0), compared with the average of 9.7 (±0.5) for the age- and gender-matched controls (p

Background and aims: The Timed up and Go Test (TUG) is recommended as a screening tool for fall risk in older people. It is assumed that this general mobility test is underpinned by physiological factors such as strength, coordination and balance. However, no studies have examined the range of physiological and psychological factors which influence performance on this test. The aim of this study was to examine the relative contributions of a range of sensorimotor, balance and psychological factors to TUG performance in a large sample of older people. Methods: 280 community-dwelling people aged 65 plus years (mean age 74.9, SD=6.4) underwent the TUG test, as well as quantitative tests of vision, peripheral sensation, strength, reaction time, balance, fear of falling, pain and vitality. Results: The time required to complete the TUG was significantly related to limitations in instrumental activities of daily living and fear of falling. Many physiological and psychological factors were significantly associated with TUG performance in univariate analyses. Stepwise multiple regression analyses identified knee strength, postural sway, reaction time, edge contrast sensitivity, MMSE score, SF12 body pain and general health scores, number of medical conditions and age as significant and independent predictors of TUG performance. Of these measures, the lower limb strength measure explained most variance in TUG times. However, other sensorimotor, balance, psychological and health measures provided important independent information. The combined set of variables explained 43.5% of the variance in TUG times (multiple r=0.65). Conclusions: Findings indicate that, in community-dwelling older people, TUG performance is influenced by lower limb strength, balance, reaction time, vision and pain, in addition to cognitive function and health status.

Background and aims: Falls causing injuries among older people and the consequences of those injuries are of increasing concern to public health practitioners. The aims of this study were to determine the incidence, characteristics and risk factors of fall injuries among the community-dwelling elderly in Shihpai, Taiwan; the impact on quality of life and health service utilization was also comprehensively studied. Methods: 1361 community-dwelling elderly who had been enrolled in the Shihpai eye study (1999–2000) were included. Subjects were interviewed and examined by trained interviewers, and data such as demographics, medical conditions, blood pressure, ophthalmic examination, fall history and quality of life (SF-36) were collected. Chi-square tests, analyses of covariance and multiple logistic regressions were performed as the main statistical methods. Results: The mean age of the participants was 72.2 (range, 65–91) years old. 16.3% of the elderly persons interviewed had experienced at least one fall; among those, up to 50% had suffered mild injuries, and the incidence of remarkable injury was 27.6%. There were no significant differences in the location or time of falling, but there were different risk factors and consequences in injury severity. Fallers with remarkable injuries had a higher incidence of hospitalization and a greater fear of falling. No statistically significant decline in quality of life with increasing severity of falling injury was identified after a 12-month follow-up period. Conclusions: Gender, visual impairment and orthostatic hypotension were identified as the major risk factors of fall injuries in the elderly. These factors should be emphasized in order to reduce fall injuries in geriatrics.
