Test-Retest Scores for Dual-Task Gait Parametersa

  • a Mean and standard deviation are given for normally distributed data. ICC=intraclass correlation coefficient, CI=confidence interval, SEM=standard error of measurement, MDC=minimal detectable change. Median and interquartile range (IQR) are given for abnormally distributed data. In case of non-normally distributed data, the Wilcoxon signed rank test value is presented instead of the t-test value to indicate differences between both tests, and Spearman correlation coefficients are presented instead of ICC values. * Significant at α<.05. ** Significant at α<.01.
