This paper presents an automatic acquisition and analytic procedure of acupuncture manipulation based on optical navigation

aiming at solving the shortcomings of existing acquisition methods of acupuncture manipulation. An acquisition holder installed at the handle tail of filiform needle was designed to display the movement trajectory of the needle during acupuncture delivery by collecting the movement trajectory of holder. The 3-month old male Bama miniature pig was selected as the experimental subject

and 6 points

"Bojian" "Qiangfeng" "Housanli" "Xiaokua" "Huiyang" (BL35) and "Baihui" (GV20)

were selected during acupuncture manipulation. The optical navigation system was used to collect the real-time data

and these data were per-processed and analyzed using mean filtering and Fourier transform. The acupuncture procedure was divided into 3 stages

inserting

lifting-thrusting

and twisting. The results showed that the accuracy was 96.3% at lifting-thrusting stage

and that was 100.0% at twisting stage. The decomposition effect of the entire procedure was satisfactory. This study provides a new approach to the quantitative analysis of acupuncture manipulation. In the future

it needs to further optimize the algorithm and expand the sample size so as to improve the accuracy of this analytic technique.
