Table 1 P-value of repeated measures analysis of variance (ANOVA) (n = 1280 steps) estimating the effects of a decrease in self-selected walking speed on mean value, standard deviation and coefficient of variation of stride time, adjusted for subject's effect (n = 29), number of trials per walking condition and left-right step asymmetry

From: Walking speed-related changes in stride time variability: effects of decreased speed

  Effect  
Stride time Decrease in preferred walking speed Subject Trials* Left-right step asymmetry† R-squared
Mean value <0.001 <0.001 0.534 0.971 0.612
SD <0.001 <0.001 0.177 0.150 0.481
CoV <0.001 <0.001 0.691 0.288 0.293
  1. SD: standard deviation,
  2. CoV: Coefficient of variation expressed in percentage and calculated from the formula: [(Standard deviation/Mean value) × 100],
  3. *: Number of trials per walking condition coded in three level (0 = first trial, 1 = second trial, 2 = third trial)
  4. †: Right and left step coded as a binary variable (0 = Right, 1 = Left)
