Fall History (fall + history)
Selected AbstractsPostural instability during reaching tasks in Parkinson's diseasePHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 3 2005Dr Emma Stack Abstract Background and Purpose. Reaching, like turning and rising from sitting, is an activity commonly associated with falls by people with Parkinson's disease. We set out to: (a) identify how people with moderate and severe Parkinson's disease performed high and low reaches and (b) to explore in detail the standard functional reach (functional reach) test and the fall histories of those who appeared unstable when reaching. Method. In this cross-sectional study, people with moderate or severe Parkinson's disease (Hoehn and Yahr Grade III or IV) were video-recorded at home, reaching above shoulder height and below knee level. Blinded observers rated stability, alignment, foot position, floor contact, use of support and reach type. Functional reach was also measured and participants were interviewed about falls. Results. Of 51 participants, 33 (65%) had moderate Parkinson's disease and 18 (35%) severe. A greater proportion of the latter used support when reaching high (p = 0.029) and aligned forward when reaching low (p = 0.015); otherwise, strategies were similar across groups. Six people (all with severe Parkinson's disease) appeared unstable when reaching: they had a shorter functional reach than the others (median 10 cm versus 18 cm; p = 0.042) and had fallen frequently (median five falls in a year), although rarely when reaching. Conclusions. Reaching tasks challenge postural stability in severe Parkinson's disease. People who appear unstable when reaching are likely to be repeat-fallers and at risk of further falls during more demanding activities. Research should address whether discouraging potentially destabilizing manoeuvres (such as squatting and toe-standing) and promoting safety-enhancing strategies (such as using support and facing forward), with or without balance retraining, reduces the risk of falling among people with severe Parkinson's disease.

Aim., This paper is a report of a review conducted to identify and summarize specific risk factors for falls in older people with dementia or cognitive impairments as documented by prospective or case,control studies. Background., People with dementia have a doubled to threefold risk for falls, but the reasons for this have not yet been fully explained. Several integrative literature reviews discuss possible specific fall risk factors. However, there is lack of a systematic evaluation of studies. Data sources., The CINAHL, PubMed, EMBASE and PsychInfo databases were searched for the period between 1980 and May 2007. Review methods., A systematic review was conducted. Cohort or case,control studies published in English or German were included if they investigated risk factors for falls or fall-related injuries in a sample consisting of participants with dementia or cognitive impairment. Two reviewers independently assessed study quality. Results., Six prospective studies were included in the review. These differed concerning samples, settings, follow-up periods and examined variables. Therefore, meta-analysis was not possible. Eight categories of risk factors emerged: disease-specific motor impairments, impaired vision, type and severity of dementia, behavioural disturbances, functional impairments, fall history, neuroleptics and low bone mineral density. Conclusion., There is lack of sound studies examining fall risk factors in cognitively impaired elders. Well-known risk factors such as motor impairment show particular characteristics in people with dementia. In addition, behavioural disturbances contribute to their high risk for falls. Further prospective studies are needed. [source] Multitasking: Association Between Poorer Performance and a History of Recurrent FallsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2007Kimberly A. Faulkner PhD OBJECTIVES: To examine the association between poorer performance on concurrent walking and reaction time and recurrent falls. DESIGN: Cross-sectional analysis. SETTING: Community. PARTICIPANTS: Three hundred seventy-seven older community-dwelling adults (mean age±standard deviation 78±3). MEASUREMENTS: Reaction times on push-button and visual-spatial decision tasks were assessed while seated and while walking a 20-m course (straight walk) and a 20-m course with a turn at 10 m (turn walk). Walking times were recorded while walking only and while performing a reaction-time response. Dual-task performance was calculated as the percentage change in task times when done in dual-task versus single-task conditions. A history of recurrent falls (,2 vs ,1 falls) in the prior 12 months was self-reported. Multivariate logistic regression models were used to predict the standardized odds ratios (ORs) of recurrent falls history. The standardized unit for dual-task performance ORs was interquartile range/2. RESULTS: On the push-button task during the turn walk, poorer reaction time response (slower) was associated with 28% lower (P=.04) odds of recurrent fall history. On the visual-spatial task, poorer walking-time response (slower) was associated with 34% (P=.02) and 42% (P=.01) higher odds of recurrent falls history on the straight and turn walks, respectively. CONCLUSION: These findings suggest that walking more slowly in response to a visual-spatial decision task may identify individuals at risk for multiple falls. Prospective studies are needed to confirm the prognostic value of poor walking responses in a dual-task setting for multiple falls. [source] Description of an advanced practice nursing consultative model to reduce restrictive siderail use in nursing homes,,RESEARCH IN NURSING & HEALTH, Issue 2 2007Laura M. Wagner Abstract Researchers have demonstrated that the use of physical restraints in nursing homes can be reduced, particularly where advanced practice nurses (APNs) are utilized. We examined the link between APN practice, siderail reduction, and the costs of siderail alternatives in 273 residents in four Philadelphia nursing homes. The majority of participants were cognitively and physically impaired with multiple co-morbidities. APNs recommended a total of 1,275 siderail-alternative interventions aimed at reducing fall risk. The median cost of siderail alternatives to prevent falls per resident was $135. Residents with a fall history experienced a significantly higher cost of recommendation compared to non-fallers. Findings suggest that an APN consultation model can effectively be implemented through comprehensive, individualized assessment without incurring substantial costs to the nursing home. © 2007 Wiley Periodicals, Inc.

Carpenter MD Abstract Objectives:, Falls represent an increasingly frequent source of injury among older adults. Identification of fall risk factors in geriatric patients may permit the effective utilization of scarce preventative resources. The objective of this study was to identify independent risk factors associated with an increased 6-month fall risk in community-dwelling older adults discharged from the emergency department (ED). Methods:, This was a prospective observational study with a convenience sampling of noninstitutionalized elders presenting to an urban teaching hospital ED who did not require hospital admission. Interviews were conducted to determine the presence of fall risk factors previously described in non-ED populations. Subjects were followed monthly for 6 months through postcard or telephone contact to identify subsequent falls. Univariate and Cox regression analysis were used to determine the association of risk factors with 6-month fall incidence. Results:, A total of 263 patients completed the survey, and 161 (61%) completed the entire 6 months of follow-up. Among the 263 enrolled, 39% reported a fall in the preceding year, including 15% with more than one fall and 22% with injurious falls. Among those completing the 6 months of follow-up, 14% reported at least one fall. Cox regression analysis identified four factors associated with falls during the 6-month follow-up: nonhealing foot sores (hazard ratio [HR] = 3.71, 95% confidence interval [CI] = 1.73 to 7.95), a prior fall history (HR = 2.62, 95% CI = 1.32 to 5.18), inability to cut one's own toenails (HR = 2.04, 95% CI = 1.04 to 4.01), and self-reported depression (HR = 1.72, 95% CI = 0.83 to 3.55). Conclusions:, Falls, recurrent falls, and injurious falls in community-dwelling elder ED patients being evaluated for non,fall-related complaints occur at least as frequently as in previously described outpatient cohorts. Nonhealing foot sores, self-reported depression, not clipping one's own toenails, and previous falls are all associated with falls after ED discharge.
