F波的紳經傳導出現機率在下肢神經根疾病的診斷價值：初步研究結果

Abstract

The purpose of this paper was to find F wave frequency in normal subjects and patients with sciatica, in order to know if there any significant difference in appearance between them, whether this kind of examination could provid a noninvasive methoid in the diagnosis of lumbar radiculopathy.Among the 22 volunteered normal subjects, there was no significiant difference between bilateral lower extremities for the mininal, mean and maximal values of tibial and deep peroneal F-wave latency and their F-frequencies. Of the 16 patients who have sciatica symptoms, 14 of them have received spinal computerized tomography examination. It was showed that herniated intervertebral disc occurred at L4-5 level in 10 of them and L5-S1 in 5 of them (one with two level leison). In these patient, F-wave study for the 6 patient who have right sciatica symptoms, there was significant difference (p＜0.05) between the two sides in the frequency rate of the deep peroneal nerve. Similar difference was also noted when it was compared with the control group. Wheras for the 10 patients with left sciatica symptoms, there was no significant between the two sides in the frequency rate of the same nerve, but when it was compared to the control group, the frequency rate of F-wave on the symptomatic side was significantly lower (p＜0.05). Disregarding whether the sciatica symptoms were on the left side or right side; if the frequency rate of the deep peroneal F-wave on the painful leg was compared to the healthy side, the F-wave frequency rate was significantly higher in the later (p＜0.05). When tibial F-wave study were performed in the patients and normal control, there was no significant difference between the two sides in the frequency rate of F-wave; including those patients who showed prolongation or absence of H-reflex on the symptomatic side. Moreover, when the minimal, mean and maximal values of tibial and deep peoneal F-wave la tency of the two lower extremities of the patients were compared to the control group, there was no significant difference.
