So this syndrome is often misdiagnosed by cervical syndrome and cervical spinal stenosis other diseases, resulted in delaying to therapy. Thus it is necessary to study changes of scalene anterior muscle in sclenus anticus syndrome by image, establish changes and create objective diagnosis criterion on image of this syndrome.

由此可见应用影像学对前斜角肌在前斜角肌综合征中的变化进行研究，确立其在影像学上的改变是有必要的，而且通过对患者的测定，建立该征临床客观诊断标准，将有助于该征的正确诊治。

Objective: 1 Measured and statisticsed areas of cross section and CT value of scalene anterior muscle on plan from superior border of C6 to C7, as a objective basement of this topic and other correspond research; 2 Compared and analysed changes between normal and patient, established diagnosis criterion on image and explored new research methods of soft tissues by image; 3 Confirmed maneuver and functional exercise are utility methods.

目的：1测定C_6上缘-C_7上缘水平前斜角肌模断面面积及CT值的正常值，作为本课题及相关研究的客观依据；2比较分析前斜角肌综合征患者与无症状者前斜角肌变化，确立该征的影像学诊断标准，初步探索软组织影像学的研究方法；3进一步确定手法配合功能锻炼是治疗该征的有效疗法。
