Statistical analysis
The 20-s average values for Number of waves (Minimum temperature (Maximum temperature (Onset time (Peak time (Average temperature (Temperature amplitude (ΔA Shapiro–Wilks test was used to test the normality assumption in continuous variables, demonstrating that they were distributed normally. Chi-square tests were used to compare the frequency of CIVDs across the three different environments, the fingers/toes, as well as between the hand and the foot. Since the aim of the study was to identify differences between matched groups the mean data for each phase were used to perform paired sample
