Evaluating Acupuncture Point and Nonacupuncture Point Stimulation with EEG: A High-Frequency Power Spectrum Analysis

Table 2

Depth of acupuncture needle insertion in the 1st and 2nd experiments; APS and NAPS (the depth of needle insertion was greater with APS than with NAPS in both the 1st and 2nd experiments).

Experiment	Stimulation	Depth in right hand (cm)	Depth in left hand (cm)
1st	APS	1.86 ± 0.16	1.88 ± 0.20
	NAPS	1.25 ± 0.13	1.26 ± 0.16
2nd	APS	1.81 ± 0.18	1.71 ± 0.15
	NAPS	1.44 ± 0.32	1.40 ± 0.40
