Acupuncture-Evoked Response in Somatosensory and Prefrontal Cortices Predicts Immediate Pain Reduction in Carpal Tunnel Syndrome

Figure 2

Symptom rating before and after acupuncture. A significant main effect of Time (pre versus post) was found for pain and paresthesia VAS score (𝐹_1,56=19.3, 𝑃<0.0001; 𝐹_1,56=5.2, 𝑃<0.03, resp.), indicating reduced pain and paresthesia after acupuncture. Post hoc testing found that local EA reduced pain and paresthesia (^∗𝑃<0.01) while distal EA reduced pain (⁺𝑃<0.05). Error bars indicate standard error of the mean.
