摘要 目的：进一步拓展F波检测的临床应用范围。方法：对42例确诊为L5/S1腰椎间盘脱出症的患者进行胫神经F波时限、波幅、相位、出现率和传导速度的检查，并对其中38例患者进行住院综合物理治疗2个月后，复查F波传导速度并作CT。结果：患侧与健侧胫神经F波的时限、波幅差异无显著意义(P＞0.05)；患侧F波的相位明显增多，传导速度减慢与健侧对比差异显著(P＜0.001)；患侧F波的出现率降低，与健侧对比差异有显著意义(P＜ 0.05)；治疗有效的病例F波传导速度比治疗前明显改善(P＜0.01)。而全部病例治疗前后CT检查椎间盘无形态学改变。结论：F波的相位、出现率和传导速度均能反映神经根的功能状态，但波幅、时限变化意义不大。认为F波传导速度是腰椎间盘突出症理想的定量评定指标。

The value of determination of F wave in the diagnosis of compression sign of lumbosacral nerve root and its value in rehabilitation/LIANG Zhenhong,XIAO Xue//Chinese Journal of Rehabilitation Medicine, 1998,13(1):11～13
Abstract Objective:To further develop the clinical significance of F wave test.Methods:42 patients diagnosed to be lumbar intervetebral disc herniation of L5/S1 were tested on time limit, amplitude, phase number, emerging rate and conduction velocity of nervi tibial F wave, and 38 patients were submitted to a control check of F wave conduction velocity and CT after they received a multiple physical treatment for two months in the hospital.Results:No significant difference was found between the difference of F wave time limit and amplitude the nervi tibial of the diseased side and healthy side (P＞0.05). The F wave phase number of diseased side incressed obviously and conduction velocity decreased (P＜0.001).The appearence rate of F wave of diseased side decreased (P＜0.05).The cases whose symptoms and body signs were improved,their F wave conduction velocity also were improved obviously after treatment (P＜0.01).But after treatment, no form change of intervetebral disc was found among all cases in comparision with that of treatment before by CT sean. Conclusion:The phase number, the appearence rate and the condution velocity of F wave could reflect the function state of nerve roots.
