Clinical study on diagnostic evaluation of conduction velocity using F-wave.
The F-wave produced from discharged impulses via the spinal cord can be used to measure the conduction velocity in the proximal area of the peripheral nerve. The F-wave conduction velocities (FWCV) of the sciatic nerve, the L5 nerve root, and the ulnar nerve were measured in patients with lesions near the spinal cord. The diagnostic value of the FWCV was then investigated by comparing the FWCV obtained values with findings in individuals without neuropathy. This study suggests that when a single nerve root is involved, there is no slowing of the FWCV of the peripheral nerve. Thus, FWCV measurement of the nerve root is one means of detecting the root lesion and of assessing the pathology.
