摘要:

[目的]以骨度分寸定位法为金标准,比较指寸定位法量取腧穴的准确性。[方法]选择形体健全的学生或患者63人,以厘米(cm)为单位测量3种手指同身寸的长度与6种骨度分寸的长度;再用每一种指寸的长度(单位:cm)分别测量每一骨度分寸的长度,所得出的寸数再与该骨度规定的寸数比较,即得出差异寸数。[结果]1)绝大多数人手指同身寸与骨度规定的分寸有差异。2)3种指寸测量脐至耻骨联合上缘,所得寸数均多于规定的5寸(同身寸,下同)。3)测量胸剑联合至脐、两乳头间距、肩胛骨内缘至后中线、肘横纹至腕横纹、腘横纹至外踝尖时,所得寸数与规定寸数比较,有多有少,双向波动。[结论]1)指寸法存在取穴误差。2)尽管指寸法存在取穴误差,但绝大多数的差异均数较小,离散度也较小,所以在取靠近骨度两端的腧穴(如靠近肘、腕、膝、踝部位的腧穴:内关、足三里、悬钟、三阴交等)时,仍可使用。3)若用指寸法量取骨度中部腧穴(如上下巨虚、条口、丰隆),须从骨度一端量起,量至中部则误差会积累到明显的程度,所以,此时指寸法要在骨度分寸的矫正下使用。4)取穴应以骨度分寸定位法、体表标志定位法、简便取穴法为主。

Abstract:

[Objective] Taking bone-length measurement as the golden standard,the accuracy of taking middle finger as an identical init on acupoint localization was compared. [Methods] Sixty more of sound student or patients were chosen. Taking cm as the unit the length of 3 kinds of fingers as an identical unit and the length of bone-length measurement were measured. The length of bone-length measurement was measured with the length of each finger as an identical unit again respectively. The obtained length was compared with the length established with bone-length measurement again. Then the difference of inch was harvested. [Results] 1)There was a difference between both methods. 2)The distance from navel to upper border of pubis junction measured with 3 kinds of finger methods was all more than the fixed 5 inches. 3)The distance from mucro sterni junction to navel,between two papillae,from interior border of omoplata to post-middle line,from elbow striated streak to wrist striated streak,from poples striated streak to external malleolus fastigium was measured and compared with the fixed inch number. Sometimes it was longer and sometimes shorter with a two-dimensional fluctuation. [Conclusion] 1)There were some errors in acupoint location with finger method but the average difference was small mostly and the vari-able degree was small also. 2)It can still be used when location of the acupoint at the two sides of bone-length measurement.(such as lo-calizing acupoint near the elbow,wrist,knee,the ankle part:Neiguan,Zusanli,Xuanzhong,Sanyinjiao etc. 3)When using finger method to localize the middle acupoint of bone-length measurement (upper and lower Juxu,Tiaokou and Sanyinjiao),the measurement should be started from one side of bone-length measurement. The errors will be accumulated when the measurement achieved at the middle position. At this time the finger method should be used under correction with bone-length measurement. 4)The acupoint localization should be mainly performed with bone-length measurement,localization method with the index of body surface,and the simple localization method.
