Abstract:
Objective: To analysis the finding of never conduction velocity(NCV) in patients with ALS and investigate the clinical significance of NCV. Methods: Keypoint was applied to estimate the NCV of median,ulnar,tibial,peroneal in 106patients with ALS and 123healthy volunteers,in which sunface electrodes was used for both stimulating and recording. Results: SCV of median and MCV of median,ulnar,peroneal in patient group was a significant difference as compared with the normal subjects;A significant difference was noted in all latency except sensory fiber of median.A significant differencence of compound muscle action potential amplitude of medial,ulnar,tibial was noted in two groups. Conclusion: NCV in patients with ALS could show abnormal slowing,so the valuation for differentiation of NCV is not so good as the clinical signs and the distribution of electromyographic abnormalities.
