By using "Acupuncture Manipulation Information Analyzing System"

the traditional reinforcing and reducing manipulations of acupuncture described in classical Chinese medical books were imitated and their parameters analyzed.It was found that in the oscillogram

the differences between the reinforcing and reducing manipulations(rapid-slow reinforcing-reducing skill

lifting-thrusting reinforcing-reducing skill) are the bigger duration of descending branch(t1) and smaller duration of ascending branch(t2) for the former

and shorter t1 and longer t2 for the later

due to slow insertion and rapid withdrawal of the acupuncture needle for the reinforcing

and rapid insertion and slow withdrawal of needle for the reducing.While for twirling reinforcing

t1t2 for predominantly-rightward twirling were found.In addition

it is supposed that those parameters as the amplitude(s)

frequency(f) and duration of one cycle(t) of the oscillogram may be related to acupuncture stimulating quantity

while t3(duration of the plateau segment)

t4(duration of the horizontal plane segment) and their variance may be associated with the stability of the acupuncture manipulation.Due to the limited literal recordation

some other traditional acupuncture manipulations can not simulate indeed

because we don't know how to perform those kinds of acupuncture manipulation.This just reflects the importance of objectivity of acupuncture manipulations.
