摘　　要：For diagnosiug lumbosacral radicuiopathy precisely, electromyogram(EMG),nerve conduction velocity(NCV),conventional H reflex and H reflex by nerve root stimulation were done in 79 patients with clinical symptoms and signs of lumbosacral radiculopathy.The rate or appearance fibrillation voltage and/or positive sharp wave in the paraspinal muscles was the highest among them.In the comparison of the affected and the healthy sides in patients with S1 radlculopathy,and of affected side and control group,H-M wave interval of H reflex by nerve root stimulation were significantly prolonged(P<0.01,P<0.05);compared with control group,the dirference or H-M wave interval between the two sides was also significantly prolonged (P<0. 05).But the differences were not so significant in patients with L5 radlculopathy.The results suggest that the abnormal changes or EMG or the paraspinal muscles and H reflex by nerve root stimulation are reliable methods of diagnosing lumbosacral radiculopathy, H reflex by nerve root stimulation can be used to differentiate L5 and S1 nerve root lesions,and measure motor conduction velocity(MCV)and sensory conduction velocity(SCV) or the proximal sciatic nerve.For diagnosiug lumbosacral radicuiopathy precisely, electromyogram(EMG),nerve conduction velocity(NCV),conventional H reflex and H reflex by nerve root stimulation were done in 79 patients with clinical symptoms and signs of lumbosacral radiculopathy.The rate or appearance fibrillation voltage and/or positive sharp wave in the paraspinal muscles was the highest among them.In the comparison of the affected and the healthy sides in patients with S1 radlculopathy,and of affected side and control group,H-M wave interval of H reflex by nerve root stimulation were significantly prolonged(P<0.01,P<0.05);compared with control group,the dirference or H-M wave interval between the two sides was also significantly prolonged (P<0. 05).But the differences were not so significant in patients with L5 radlculopathy.The results suggest that the abnormal changes or EMG or the paraspinal muscles and H reflex by nerve root stimulation are reliable methods of diagnosing lumbosacral radiculopathy, H reflex by nerve root stimulation can be used to differentiate L5 and S1 nerve root lesions,and measure motor conduction velocity(MCV)and sensory conduction velocity(SCV) or the proximal sciatic nerve.
