Title: F-wave Latency Conduction Velocity of the Ulnar Nerve among Normal Sudanese Adults
Author: Hussein, Wafaa Abdel Raouf; Eltahir, Ammar
Abstract: F-waves, one of the late responses produced by antidromic activation of Motoneurons by supramaximal stimulation, are one of the most frequently used studies in clinical neurophysiology. They are particularly useful for the diagnosis of proximal nerve lesions and have been found of use in diagnosis of certain types of peripheral neuropathy such as Guillian Barre Syndrome GBS, when other nerve conduction studies have been normal, as well in diabetic neuropathy. They are variable in latency, amplitude, and configuration, and are recorded over a muscle innervated by the stimulated nerve. This is the first study to date that evaluates F-wave Latency in normal Sudanese adults to determine the mean value for the F-latency conduction velocity, sex and age related changes in the F-latency conduction velocity, and the relationship between body height, span and F-wave latency. Values of F-latency conduction velocity obtained in this study reveals normal Sudanese figures similar to universal findings, with sex but no age related changes in F-latency conduction velocity, females showing faster conduction in females, and F-wave distal latency directly proportional to body height and span.
