Study on acupuncture at acupoints using tissue Doppler imaging / 中华超声影像学杂志

ABSTRACT

Objective To observe the tissue displacements between the acupoints and non-acupoints using tissue Doppler imaging.Methods Acupuncture bilaterally were performed at Zusanli,Qvchi and corresponding control points 1 cm lateral to them in 30 healthy human subjects.Monitored by the dynamic system for detecting the force of acupuncture needle during the acupuncture process,tissue Doppler imaging was recorded on the condition of keeping the depth of needle insertion and the rotational torque at the same level approximately.Tissue Doppler imaging was also recorded before and after the acupuncture.Results The mean tissue displacements of the aforementioned 2 acupoints were all significantly greater than those of the corresponding non acupoints(P＜0.05).The mean tissue displacements after the acupuncture were all significantly greater than those before the acupuncture(P＜0.001).Conclusions Tissue Doppler imaging provides a new thought and method for the research of the acupoints.
