Abstract:
HFreq EA treatment (80–120Hz) resulted in a marginally significant difference (SC) in HRV indicators (increased HF, decreased LF norm, increased HF norm and decreased LF/HF) when compared to LFreq EA treatment (20–40Hz), as measured in the 0–5 min post-treatment period. There was an overall higher PNS cardiac control. The BI showed an increase towards lowering of the head and neck in a calm posture during the 15–20 min period of EA application (more during HFreq EA treatment) compared to the period 5 min after completion of the clinical stressor (SC), with no significant changes in licking and chewing. More specifically, it is important to note that minimal BI lowering of head and neck, and licking and chewing were observed during the clinical stressor.
