Table 1.
Median and interquartile range for autonomic indices during the REST runs and the PAIN runs. Significantly different values (Wilcoxon signed-rank test, p<0.05) between REST and PAIN are reported in italics. bpm, beats per minute; HR, heart rate; HRvar, HR variance; LF-HRV, low-frequency component of heart rate variability; HF-HRV, high-frequency component of heart rate variability.
