The results of studies performed by the authors show that time measurements of proprioceptive muscular reflexes (triceps surae and tibialis posterior reflexes) may be considered a valuable addition to methods of topical diagnosis of radicular disturbances in the lumbosacral region. The reflexes were tested in twenty normal subjects. There were found an intraindividual constancy of the respective reflex time with a maximum deviation of 2 ms as well as a lateral variability up to 1.3 ms. Radicular compressions resulted in an increase in reflex time by 2 to 66 ms or failure of the reflex potential to be recorded. The pathological cases were compared with clinical and neurological studies, positive myelographies using radiopaque substances, and results of surgical operations. Compared with the results of surgical operations, changes in reflex time indicated damage to the reflex arc in ninety percent of the cases.
作者进行的研究结果表明，本体感受性肌肉反射（腓肠肌和胫后肌反射）的时间测量可被视为对腰骶部神经根紊乱局部诊断方法的有价值补充。在20名正常受试者身上测试了这些反射。发现各自反射时间存在个体内稳定性，最大偏差为2毫秒，以及高达1.3毫秒的侧向变异性。神经根受压导致反射时间增加2至66毫秒或无法记录到反射电位。将病理病例与临床和神经学研究、使用不透射线物质的阳性脊髓造影以及手术结果进行了比较。与手术结果相比，反射时间的变化在90%的病例中表明反射弧受损。
