There are several methods of acupuncture for stiff shoulders such as pecking stimulation, LFEA, and (SSP). These three types of stimulation were given to the suprascapular region and variation of blood flow Silver Spike Point in the skin and the muscle was observed. In our study, we made it a rule to take the skin temperature and the deep temperature of 1cm deep under the skin for the index. As a result, concerning the muscle blood stream at the stimulus point, it was found that LFEA and SSP caused a significant increase in the muscle blood flow and pecking stimulation also showed a 43% increase in the muscle blood flow. The skin blood flow showed the same effect as the muscle blood flow. Furthermore, about the influence of stimulation on the remote region from the suprascapular region we observed variation of the skin temperature on the back of hand and the index finger, it showed a transient decrease in blood flow with pecking stimulation and LFEA, whereas there is little variation with SSP. From this observation, it was indicated that pecking stimulation without any muscle contraction improved an amount of the blood stream at the stimulated region and about the peripheral circulation to the remote region the inserting technique such as pecking stimulation and LFEA will unfluence it.
Studies have been made by Tsukuba University on the sympathomimetic reaction by various stimulus such as heat, acupuncture, moxibustion and pressure. We performed stimulus with acupuncture anesthesia method on 10 healthy adult men to determine the effect of acupuncture stimulus. They were given 3 types of stimulus to evaluate the effect of acupuncture stimulus on blood pressure and post stimulus and given a T-test among these stimulus. We made use of 8 points as stimulus points: right and left LI-4, HC-6, SP-6 and ST-6. 1; In the electro-acupuncture stimulus for 30 minutes with 1Hz, systolic pressure decreased significantly, whereas diastolic pressure increased. 2; In the situ stimulus for 30 minutes, it was found that, in average, systolic pressure was decreased and diastolic pressure was increased but they showed no significant difference. Pulse pressure was significantly decreased. 3; In the spotted skin electro stimulus for 30 minutes with 1Hz, systolic pressure decreased significantly, whereas diastolic pressure showed no variation as well as the control group. It is supposed that acupuncture stimulus and electro stimulus made for peripheral vessel contraction as well as palmus restrain, whereas the spotted skin electro stimulus made for palmus restrain.
