Validity of an Index of Self-reported Walking for Balance and Falls in Elderly Women

Abstract
We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0.32-0.62) with a number of clinical tests of bal ance. With force plate measures of balance, the highest correlations were with the length of the path of centre of pressure (COP) in the frontal ( r = 0.26, 95% confidence interval (CI) = 0.19-0.33) and in the sagittal plane ( r = 0.24, 95% CI = 0.14-0.34). The COP measures, which were taken under... (More)

With force plate measures of balance, the highest correlations were with the length of the path of centre of pressure (COP) in the frontal ( r = 0.26, 95% confidence interval (CI) = 0.19-0.33) and in the sagittal plane ( r = 0.24, 95% CI = 0.14-0.34). The COP measures, which were taken under dual task conditions, also had rather low correlations with the clinical tests of balance and walking, the highest one being 0.27, between tandem stance and the length of the COP path in the frontal plane. To have a poorer score on the RW-index predicted more falls (odds ratio (OR) = 1.83, p = 0.03), and fall-related fractures (OR = 1.83, p = 0.03) during a 1-year follow-up. The results show that easily collected clinical information provided by older people regarding walking and balance contributes in identifying subjects at increased risk of falling and fall-related fractures.
