In order to acquire normal values, patellar and ankle tendon reflexes were measured bilateral in 51 healthy subjects. The reflexes were mechanically evoked with a hand-held hammer which was connected to the trigger input of a two-channel EMG system. For each reflex simultaneous registration took place from surface electrodes on two different locations. The dependence of the latency on body length and age is described as well as the left-right difference and the intra-individual variability. Using similar measurement conditions significantly longer latencies were found than those published earlier. The importance of well defined placement of the electrodes when comparing acquired latencies with normal values is shown.
为了获得正常值，对51名健康受试者双侧测量了髌腱和跟腱反射。使用连接到双通道肌电图系统触发输入的手持锤子机械诱发反射。对于每个反射，同时从两个不同位置的表面电极进行记录。描述了潜伏期与身体长度和年龄的关系，以及左右差异和个体内变异性。在相似的测量条件下，发现潜伏期比早期公布的明显更长。显示了在将获得的潜伏期与正常值进行比较时，电极精确定位的重要性。
