【摘要】：目的:超声下应用电针不同波形刺激外金津及外玉液,观察颏舌肌收缩的即刻效应。方法:应用序贯试验设计,将14例健康受试者随机分为A、B两组,A组为先给予电针连续波(频率为30Hz)刺激外金津、外玉液腧穴,经过3天的洗脱期后再给予电针断续波(断续比为1:1)刺激外金津、外玉液腧穴,在超声下检测颏舌肌的肌肉厚度,以评价颏舌肌收缩的强度。B组为先给予电针断续波(断续比为1:1)刺激,经过3天的洗脱期后,再给予电针连续波(频率为30Hz)刺激。选穴及检测方法同A组。综合两组数据,对比分析,应用开放型双侧序贯t检验进行14例受试者的数据分析,颏舌肌收缩的强度通过超声下测量受试者仰卧位颏舌肌的厚度来评价。结果:1.在超声下引导针灸针刺外金津、外玉液,均向对侧耳根方向进针,两针针尖方向夹角约为90°;对于针灸进针的深度,在沿外金津、外玉液针刺颏舌肌时,当针灸针刺入腧穴后有镂空感,再次感到阻力时,为刺中颏舌肌,在超声下得到证实。2.电针连续波与电针断续波针刺外金津、外玉液,超声下观察颏舌肌的肌肉厚度,均能引起颏舌肌的收缩;在纳入第14例受试者时,超声下测量颏舌肌的肌肉厚度,经分析后,zi=6.537Ui= 5.51,试验线触及上界U(即接受电针连续波疗效优于电针断续波或接受电针断续波疗效优于电针连续波),且∑di0,故接受电针断续波疗效优于电针连续波。结论:1.选穴外金津、外玉液进针针刺颏舌肌,可以明显引起颏舌肌收缩,扩张上气道。2.超声下能直观、灵敏、动态的观察并测量沿外金津、外玉液针刺颏舌肌,肌肉收缩的情况、肌肉的功能状态及活动状态。3.超声下沿外金津、外玉液引导进针针刺颏舌肌,针灸及接通电针均可引起颏舌肌的收缩,改善肌肉的功能状态和活动状态,其中,电针断续波疗效优于电针连续波。
[Abstract]:Objective: to observe the immediate effect of genioglossus contraction by electroacupuncture (EA) with different waveforms. Fourteen healthy subjects were randomly divided into two groups: group A was treated with electroacupuncture continuous wave (frequency of 30 Hz) to stimulate external Jinjin and external jade acupoints, after three days of elution period, they were given electroacupuncture intermittent wave (1: 1) to stimulate external Jin Jin. The muscle thickness of genioglossus muscle was measured under ultrasound. Group B was stimulated by electroacupuncture intermittent wave (intermittent ratio 1: 1). After 3 days of elution, the muscle thickness of genioglossus was measured. The data of 14 subjects were analyzed by using open bilateral sequential t test by comparing and analyzing the data of the two groups, which were given electroacupuncture continuous wave (frequency 30 Hz) stimulation and the method of acupoint selection and detection was the same as that of group A. The intensity of genioglossus contraction was evaluated by measuring the thickness of genioglossus in supine position under ultrasound. The angle between the two needles in the direction of the needle is about 90 掳. For the depth of acupuncture and moxibustion into the needle, when the genioglossus is pricked along the outer Jin Jin and the external jade solution, when the acupuncture needle has a sense of hollowed-out after being punctured into the acupoint and feels the resistance again, it is the middle genioglossus muscle. It was confirmed by ultrasound that electroacupuncture continuous wave and electroacupuncture intermittent wave can cause the contraction of genioglossus muscle, both of which can cause contraction of genioglossus muscle in the 14th case, and the thickness of genioglossus muscle can be induced by electroacupuncture continuous wave and electroacupuncture intermittent wave acupuncture on outer Jin Jin, external jade liquid and ultrasonic observation of genioglossus muscle. The muscle thickness of genioglossus was measured by ultrasound. After analysis, 6.537 Ui = 5.51, the test line reached the upper bound U (that is, the curative effect of receiving electroacupuncture continuous wave is better than that of electroacupuncture intermittent wave or receiving electroacupuncture continuous wave, and 鈭，
