Abstract: Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.
