Manuscript Feedback

Dr. Francesca Burgio of Hospital San Camillo and the Villa Salus Foundation has coordinated a Delphi procedure on relevant items that need to be recorded and reported in transcranial magnetic stimulation (TMS) procedures. The document is now in draft form and we welcome public comment that will help in finalizing the document. Please send your comments to by November 6, and feel free to share this opportunity with your colleagues. The final manuscript will be published in Clinical Neurophysiology.

Message from the IFCN President

Dear Colleagues,

The Japanese Society of Clinical Neurophysiology celebrates its 50th anniversary this year. Congratulations to a very active and continuously successful society. Documents from 50 years with many illustrations can be downloaded from our history page.

There are still a few more weeks before the September 30 application deadline for IFCN’s 2021 Education and Research Fellowships. You can find the application requirements on our website.

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

Date: Saturday, November 13, 2021 at 8:00 AM EST (2:00 PM CEST)

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.

IFCN Publications

The IFCN has two official journals Clinical Neurophysiology and Clinical Neurophysiology Practice.
Clinical Neurophysiology Journal Cover

Clinical Neurophysiology Journal

Volume 132, Issue 10 (October 2021)

Clinical Neurophysiology is the official journal of IFCN and its member Societies. It has been adopted as the official journal of the Italian Society of Clinical Neurophysiology, the Czech Society of Clinical Neurophysiology, the Brazilian Society of Clinical Neurophysiology and the International Society of Intraoperative Neurophysiology.

Clinical Neurophysiology is dedicated to publishing scholarly reports on the pathophysiology underlying diseases of the peripheral and central nervous system of humans.

Clinical Neurophysiology Practice Journal

Clinical Neurophysiology Practice (CNP) is a new Open Access journal that focuses on clinical practice issues in clinical neurophysiology including relevant new research, case reports or clinical series, normal values and didactic reviews. It complements Clinical Neurophysiology which focuses on innovative research in the specialty. It has a role in supporting established clinical practice, and an educational role for trainees, technicians and practitioners.
