Figure 2

(a) There is no significant difference among the baseline weight of all three groups (n = 36) (). (b) No significant difference of the baseline pain threshold among all three groups (n = 36) (). (c) Pain threshold at different time points of different groups (n = 6); there is a rhythm pattern and CFA injection and acupuncture can affect the rhythm pattern. (d) Change of pain threshold after acupuncture compared with the model group was calculated at different time points; acupuncture is most effective at ZT12, while least effective at ZT0 and ZT16 (n = 6).
