Is the Tinetti Performance Oriented Mobility Assessment (POMA) a feasible and valid predictor of short-term fall risk in nursing home residents with dementia?

Abstract

Application of the POMA in populations with moderate to severe dementia is hampered by feasibility problems. Its implementation in clinical practice cannot therefore be recommended, despite an acceptable predictive validity. To refine our findings, large prospective studies on the predictive validity of the POMA in populations with mild, moderate and severe dementia are needed. In addition, the performance of mobility assessment methods that are less dependent on cognition should be evaluated.

Reliability of the Berg Balance Scale as a Clinical Measure of Balance in Community-Dwelling Older Adults with Mild to Moderate Alzheimer Disease: A Pilot Study

“…Previous research on the psychometric properties of these balance scales has been conducted in a mixed population of patients with mild to moderate AD or a sample with mixed dementia types. 5,12 The relative proportions of people with mild and moderate disease could affect overall test performance between samples, and therefore this information should be included in study sample descriptions because test performance may decrease with increasing disease severity. Previous evidence on the FRT's reliability has been contradictory and limits knowledge translation recommendations.…”

“…1 Some of the existing literature on the reliability of physical performance measures in people with dementia is limited by the use of a sample consisting of participants with a non-specific diagnosis of dementia and no quantification of disease severity or disease sub-type. [2][3][4][5][6] Falls are a major cause of disability and dependence in older adults, particularly in those with dementia: 7 People with dementia have an annual fall risk of 60%-80%, 8 twice that of community-dwelling older adults with normal cognition. People with dementia who fall are also 5 times more likely to be admitted to an institution than those who do not.…”

Measuring physical function in people with dementia: a psychometric investigation

“…The setting of the studies were split between community care (n = 7) and long term care (n = 5) (Blankevoort et al, 2013;B. Fox, T. Henwood, C. Neville, & J. Keogh, 2014a;McGough, Logsdon, Kelly, & Teri, 2013;Sterke et al, 2010;Tappen et al, 1997).…”

“…One study was a three month longitudinal, follow-up predictive validity study on falls (Sterke et al, 2010). The remaining eleven studies were cross sectional in nature (Alencar et al, 2012;Blankevoort et al, 2013;Bramell-Risberg et al, 2005;Fox, Henwood, et al, 2014a;McGough et al, 2013;Nordin, Rosendahl, & Lundin-Olsson, 2006;Ries et al, 2009;Suttanon et al, 2011;Tappen et al, 1997;V.…”

“…The final study measured construct validity, specifically hypothesis testing (Bramell-Risberg et al, 2005). Eight studies examined two psychometric properties (Blankevoort et al, 2013;Fox, Henwood, et al, 2014a;McGough et al, 2013;Nordin et al, 2006;Ries et al, 2009;Sterke et al, 2010;Suttanon et al, 2011;Wittwer et al, 2008). The most common combination was reliability and measurement error, examined by six studies (Blankevoort et al, 2013;Fox, Henwood, et al, 2014a;Nordin et al, 2006;Ries et al, 2009;Suttanon et al, 2011;Wittwer et al, 2008).…”
