Averaged psychophysical response (N = 16). (A) The percentage of subjects who reported having experienced the given sensation (at least one subject experienced the seven sensations listed). The occurrence frequency of numbness, fullness, and soreness was found greater for the ACUP under Fisher's exact test (*P < 0.01, **P < 0.005). (B) The intensity of reported sensations measured by an average score (with standard error bars) on a scale from 0 denoting no sensation to 10 denoting an unbearable sensation. The average stimulus intensities (mean ± SE) were approximately similar during acupuncture at the ST36 (2.4 ± 1.7) and NMP (2.2 ± 1.9).
