Masterclass by IFCN – Clinical Use of F-Wave Measures

Dear NVKNF Members,

It is now time to mark your calendar and register for our Masterclass by IFCN on Saturday 13 November 2021 at 8:00 AM EST / 2:00 PM CEST.

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.

The Masterclass by IFCN presentations were created in response to a call from IFCN member 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 is available complimentary to all registrants. Our previous lectures can be viewed on our website if you are not able to join us live.

Registration is now open. The Masterclass by IFCN series have been organized on Zoom.com, a very easy-to-use webinar application. Please allow yourself 5 – 10 minutes to get set up before the start of the webinar.

I look forward to seeing you on Saturday 13 November 2021 at 8:00 AM EDT / 2:00 PM CET.

Professor Walter Paulus
IFCN President
