Magnetic stimulation was utilised to diagnose lumbosacral motor radiculopathy non-invasively. Magnetic coil stimulation estimated peripheral motor nerve conduction time (MNCT) which, used in combination with F response, allowed calculation of "motor root conduction time (MRCT)," response being recorded from abductor hallucis. Twenty-five normal controls and 26 patients with lumbar spondylosis were studied. The mean interside difference (left minus right) of MRCT in the control was +0.06 msec (range: -0.88 to +0.74 msec). On clinical and radiological grounds, patients with spondylosis were grouped into those with: (I) no lumbosacral root compression, (II) root compression without motor sign, and (III) root compression with motor deficit. All patients in group III and 36% of cases of group II had MRCT significantly prolonged on the affected side.
磁刺激被用于非侵入性诊断腰骶部运动神经根病。磁线圈刺激可估计周围运动神经传导时间（MNCT），将其与F波相结合，可计算“运动神经根传导时间（MRCT）”，记录的反应来自拇展肌。研究了25名正常对照者和26名腰椎病患者。对照组MRCT的平均双侧差异（左侧减去右侧）为+0.06毫秒（范围：-0.88至+0.74毫秒）。根据临床和影像学依据，将腰椎病患者分为：（I）无腰骶神经根受压，（II）神经根受压但无运动体征，以及（III）神经根受压伴有运动功能障碍。III组的所有患者和II组36%的病例患侧的MRCT明显延长。
