Using self-report and speed to screen for gait limitations

The purpose of this study was to describe the point prevalence of gait limitations among elderly women participating in community health screenings. Ninety-six community-dwelling women (mean age = 75.2 years) participated. Individuals were considered to have limitations if: (1) they self-reported their health limiting them when walking "a block," "several blocks," or "more than one mile," or (2) their speed over 7.62 meters was below 1.22 meters/second. More elders were identified with limitations by self-report (n = 54) than by gait speed (n = 36). Using both methods, 66 elders (68.8%) were noted to have gait limitations. Interestingly, there was poor agreement (kappa = .152) between self-report and gait speed as indicators of gait limitations. Thirty women who reported walking limitations did not appear limited by virtue of the speed test and 12 women who reported no limitations did not surpass the speed criterion. If nonobvious limitations are to be identified in women attending health screenings, both self-report and measured speed may be better than either indicator alone.
