Abstract
- <bold>Objective: </bold>To assess whether loss of consistency or systematic measurement error is introduced by allowing older individuals to use a cane during measurement of self-selected walking speed (SSWS).<bold>Study Design and Setting: </bold>Observational study of women aged 65+ (Women's Health and Aging Study I, n=1,002).<bold>Results: </bold>Of individuals who use a cane in daily life, 201 (50.76%) did not use an aid during testing. The Coefficient of Variation was low in individuals who reported cane use in daily life but did not use one in testing (10.72%), and did not vary substantially if a cane was used (12.04%). The Intra-Class Correlation Coefficient was high: 0.958 for those who reported cane use in daily life but did not use one during testing and 0.962 for those who used a cane. In both groups, Bland-Altman plots revealed a small systematic difference between the first and second trials. There was no evidence of effect modification of the association between SSWS and mobility disability by cane use during testing.<bold>Conclusion: </bold>This observational study found neither evidence of poorer consistency nor increased measurement bias in SSWS recorded while using a cane compared to using no assistive device.
