SC and HR response to EA stimulation in the active and passive coping condition groups. A: SC response amplitude showed a greater increase in the AC group compared to the PC group, suggesting increased sympathetic activation under AC. B: HR response was similarly biphasic (early decrease followed by later increase) was similar for both groups. n.b. *< 0.05, **< 0.01, ***< 0.001, ***< 0.0001. The error bars indicate the standard deviation.
