中指同身寸取穴定位與性別及身體質量指數之相關研究

Study of the Relationship between the Acupuncture Point Acquisition by the Method of Middle Finger-Tongshencun in Different Groups of Gender and Body Mass Index

為釐清「針灸」取穴時常用的「中指同身寸」度量法是否一體適用於男性與女性、各類型體 格，本研究經由實際測量48位健康醫學生的中指同身寸長度與身高、體重、腕寬、腕厚、臂長及尺膚長，以單變數與多變數統計方法進行分析。依據研究結果建議，當醫師與病人不同性別時，可以 醫師的右手中指同身寸長度依比例原則來替代患者的右手中指同身寸長度；根據中指同身寸長度等比例取前臂穴位時，女性患者宜依等比例「放大」，男性患者則宜依等比例「縮小」；同時觀察到肥胖組女性的雙手與正常組女性的左手是為最適宜根據中指同身寸等比例取穴的族群。最後依據多變項線性迴歸結果，可得出中指同身寸長度的預測因子及預測公式，以供臨床與後續研究之用。

We measured the middle finger-tongshencun, body height, body weight, body mass index, the width of wrist, the thickness of wrist, the length of forearm, and the length of chi-fu of 48 healthy medical students to clarify that if the acupuncture point acquisition through middle finger-tongshencun were suitable for all type of BMI and gender. And we use the univariate and multivariate analysis as the statistics. Based on the result, we recommended four suggestions. The first, when the physician and the patient had different gender, the physician could use his or her own middle finger-tongshencun to estimated the patient's middle finger-tongshencun according to the principle of proportionality. The second, when we orientate one acupuncture point according to the principle of proportionality by one's middle finger-tongshencun, we should large it on the female patient body but lessen it on the male patient body. The third, the female population within the group of BMI > 25 and 18.25 <23.5, both hands and left hand respectively, are the most two suitable groups for the application of middle finger-tongshencun. The last, according to the multivariable-linear regression, we got the predictor and its formula of the middle finger-tongshencun, thus, the tongshencun point acquisition through the method of middle finger-tongshencun could be applied to clinical areas and the further relative study.
