The latency of the knee tendon reflex (KTR) in the vastus medialis muscle was measured by eliciting the reflex manually with a metal hammer. Normal values were obtained in a reference group of 35 subjects. The difference in right and left KTR was used as the parameter in the investigation of 20 patients with a proven L3 or L4 monoradicular syndrome; it was abnormal in 65% of the cases. In 10 patients an asymmetrical KTR was the only relevant abnormality in the combined electromyography and reflex study. Measurement of the KTR seems to be useful in the assessment of patients suspected of a lumbar radicular syndrome.
通过用金属锤手动引出反射来测量股内侧肌的膝腱反射（KTR）潜伏期。在35名受试者的参照组中获得了正常值。将20例经证实为L3或L4单神经根综合征患者的左右KTR差异用作研究参数；65%的病例结果异常。在10例患者中，不对称KTR是肌电图和反射联合研究中唯一相关的异常情况。KTR测量似乎有助于评估疑似腰椎神经根综合征的患者。
