跟腱反射时间与体内甲状腺素水平密切相关。为进一步开展这方面的研究,我们用电话耳机改装成传感器,用心电图机(或生理记录仪)记录跟腱反射波,获得满意效果。现将组装及使用过程简述如下: 取阻抗为500Ω(200～1000Ω均可)的电话耳机一只,除去膜片,固定在一可自由升降的支架上,耳机引线与心电图机红、黄导联线连接。另取一2×5cm之软铁片,用心电图肢导联绑带绑在受检者足跟底部。受检者跪于软椅,手扶椅背,小腿自然放松。这时,铁片朝外并与地面垂直,将耳机靠近软铁片(二者相距以1cm为宜)。敲击跟腱,小腿三头肌的收缩与舒张即带动软铁片运动,
Achilles tendon reflex time and the level of thyroid hormone are closely related. In order to carry on the research in this respect further, we use the telephone earphone to transform into the sensor, use the electrocardiograph (or physiology recorder) to record the Achilles tendon reflex wave, obtains the satisfactory result. Now the assembly and use of the process is as follows: Take the impedance of 500Ω (200 ~ 1000Ω can be) a telephone headset, remove the diaphragm, fixed on a free-standing stent, earphone lead and electrocardiograph red, yellow guide Connection. Another take a 2 × 5cm of soft iron sheet, ECG lead strap tie tied to the bottom of the heel of the subjects. Subjects kneeling on a soft chair, arm chair back, legs naturally relaxed. At this moment, the iron piece is facing outward and perpendicular to the ground, and the earphone is near the soft iron piece (the distance between them is 1cm). Percussion Achilles tendon, triceps triceps contraction and relaxation that lead to soft iron movement,
