MasterClass Ifcn


The Masterclass by IFCN presentations were created in response to a call from IFCN members societies for more high quality, complimentary, online educational content. The series will provide a new presentation every month from top clinical neurophysiologists around the world, and each will include time for discussion with the lecturer following the presentation.

Providing the best in contemporary clinical neurophysiology education delivered in the most optimal format is the primary educational goal of the IFCN. As such, Masterclass by IFCN will be available complimentary to all registrants.


The Masterclass by IFCN presentation:

The Clinical Use of F-Wave Measures on Saturday, November 13, 2021 at 8:00 AM EST (2:00 PM CEST)


Prof Kimura

Professor Jun Kimura will present The Clinical Use of F-Wave Measures

F wave results from the backfiring of antidromically activated anterior horn cells. Its latency represents motor conduction along the entire peripheral axons including the most proximal segment. Clinical assessment calls for determination of a surface distance to adjust for differing nerve lengths or the patient’s height with the use of a nomogram. Studies of F wave provide a most sensitive measure of abnormality for a variety of neuropathies, but not for a focal nerve lesion such as radiculopathies. F wave also serves as a means of testing the excitability of the anterior horn cells, showing a progressive suppression after a few hours of volitional muscle relaxation. Thus, its absence, usually taken as a sign of conduction block of the peripheral motor axons, may also result from suppression of spinal motor neurons.
