Changes in gait speed of 0.10 to 0.20 m s(-1 ) may be important across multiple patient groups
RATIONALE , AIMS AND OBJECTIVES Walking speed is an important performance variable , but information on the minimal clinical ly important difference ( MCID ) for the measure has not been consoli date d. In this review , we aim ed to summarize information on the MCID for change in comfortable gait speed measurements for patients with pathology .
Meaningful improvement in gait speed in hip fracture recovery.
OBJECTIVES To estimate meaningful improvements in gait speed observed during recovery from hip fracture and to evaluate the sensitivity and specificity of gait speed changes in detecting change in self-reported mobility . DESIGN Secondary longitudinal data analysis from two r and omized controlled trials SETTING Twelve hospitals in the Baltimore , Maryl and , area . PARTICIPANTS Two hundred seventeen women admitted with hip fracture . MEASUREMENTS  Usual gait speed and self-reported mobility ( ability to walk 1 block and climb 1 flight of stairs ) measured 2 and 12 months after fracture . RESULTS Effect size-based estimates of meaningful differences were 0.03 for small differences and 0.09 for substantial differences . Depending on the anchor ( stairs vs walking ) and method ( mean difference vs regression ) , anchor-based estimates ranged from 0.10 to 0.17 m/s for small meaningful improvements and 0.17 to 0.26 m/s for substantial meaningful improvement . Optimal gait speed cutpoints yielded low sensitivity ( 0.39 - 0.62 ) and specificity ( 0.57 - 0.76 ) for improvements in self-reported mobility . CONCLUSION Results from this sample of women recovering from hip fracture provide only limited support for the 0.10-m/s cut point for substantial meaningful change previously identified in community-dwelling older adults experiencing declines in walking abilities . Anchor-based estimates and cut points derived from receiver operating characteristic curve analysis suggest that greater improvements in gait speed may be required for substantial perceived mobility improvement in female hip fracture patients . Furthermore , gait speed change performed poorly in discriminating change in self-reported mobility . Estimates of meaningful change in gait speed may differ based on the direction of change ( improvement vs decline ) or between patient population
