中枢神经活动的基本方式是反射,跟腱反射是神经系统常用的检查方法,但一般都是定性观察,如:反射亢进、减弱等。而该反射的定量研究报导较少,国外1958年Lawson首次用电磁感应方法测定了跟腱反射时,国内1961年张蕙芬,迟家敏等人开始应用此法检查甲状腺的机能。我们从1981年开始,采用这种方法测定了139例正常人 Central nervous activity is the basic way of reflection, Achilles tendon reflex is a common method of inspection of the nervous system, but are generally qualitative observations, such as: hyperreflexia, decreased and so on. However, there are few reports about the quantification of this reflection. When Lawson first measured the Achilles tendon reflex in 1958 by using the electromagnetic induction method, the domestic application of the method of thyroid function was started by Zhang Huifen and Chi Jiamin in 1961 in China. We started in 1981, using this method measured 139 normal people
