To observe the influence of different acupuncture manipulations at Zusanli (ST 36) on blood perfusion of skin microcirculation in healthy volunteer subjects.
A total of 10 healthy volunteers were recruited in the present study. Acupuncture manipulations of lifting-thrusting reinforcing and reducing, uniform reinforcing-reducing, and simple needle insertion were applied to right Zusanli (ST 36) for 2 min. Changes of blood perfusion in the right Zusanli (ST 36) area were detected 1 min, 5 min, 10 min, 15 min, 20 min, 25 min and 30 min after acupuncture stimulation, respectively by using a Pericam Perfusion Speckle Imager. The interval between two detections for different needling manipulations was 2 days at least.
In comparison with pre-acupuncture stimulation, the blood perfusion levels of the skin microcirculation around the right Zusanli (ST 36) region were significantly increased from 1 min to 10 min following simple needle insertion, from 5 min to 30 min after uniform reinforcing-reducing manipulation, from 1 min to 30 min after reinforcing manipulation, and from 1 min to 25 min following reducing manipulation, respectively (P < 0.05, P < 0.01), and the effects of reinforcing manipulation were apparently superior to those of the reducing, uniform reinforcing-reducing manipulations and simple needle insertion in upregulating blood perfusion level (P < 0.05, P < 0.01).
Lifting-thrusting reinforcing, reducing, uniform reinforcing-reducing manipulations of acupuncture needle, and simple needle insertion at Zusanli (ST 36) can obviously increase blood perfusion level in normal volunteer subjects, and the effect of reinforcing manipulation is apparently better.
