Table 3 Mean values of autonomic nervous system indices derived from APG

From: Evaluation of mental stress by physiological indices derived from finger plethysmography

 

HF (ms2)

LF/HF

Pre-task

5.97 ± 0.70

1.03 ± 0.15

CWT-1

5.25 ± 0.91

1.06 ± 0.20

CWT-2

5.11 ± 0.82

1.12 ± 0.20

CWT-3

4.95 ± 0.98

1.12 ± 0.30

Post-task

5.88 ± 0.59

1.07 ± 0.13

  1. Values are given as mean ± standard deviation (n = 31). APG, acceleration plethysmography; CWT, Stroop color-word conflict test; HF, High-frequency component; LF, low-frequency component; post-task, rest period after CWT; pre-task, rest period before CWT. Significant differences were seen in all stages of HF (P < 0.001) and between Pre-task and Post-task of LF/HF (P < 0.05). (Wilcoxon signed-ranks test).
