IFCN – President’s message

Dear Colleagues,

“Characterizing Vocal Tremor in Progressive Neurological Diseases via Automated Acoustic Analyses” is the CLIPNH Editor’s Choice for May 2020. This article focuses on the often-overlooked voice tremor. A quasi-rhythmic fluctuation in pitch and loudness of the voice secondary to involuntary oscillatory movements in speech-related muscles, voice tremor is frequently not thoroughly investigated. Professor Ziemann and I encourage the reading of what Professor Hlavnicka and colleagues found when they examined voice tremor in a large cohort of 240 patients with different neurological diseases, using automated amplitude and frequency analysis of speech recordings of the vowels /a/ and /i/.

This message contains links to resources of relevance to the CN community regarding the COVID-19 pandemic. Providing a forum to exchange knowledge in relation to Clinical Neurophysiology is what the IFCN is here to do; please continue to share your experiences via this OpenBlog.

In order to provide the best possible knowledge exchange in Clinical Neurophysiology we ask you to answer five new questions in this IFCN survey focused on the human toll that the COVID-19 virus has eventually taken within your workplace. You are welcome to provide “yes” or “no” answers, or you can share additional comments.

Non COVID-19 activities go on. Worth mentioning is an update of “Terminology in Neuromuscular Electrodiagnostic Medicine and Ultrasound.” This endeavor is a joint effort between the IFCN and the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM).

The CN community mourns the passing of Jasper Daube, MD, a neurology pioneer (hot link to obt.). Dr. Daube and François Mauguière were editors for the IFCN Handbook Series. The success of the first series has created a demand to a secondHandbook Series. Mark Hallett, Marc Nuwer, Margitta Seeck, and Ulf Ziemann are organizing this endeavor.

During these challenging time, nefarious activities tend to increase making use of Covid-19 concerns. Please be aware that the IFCN has not and does not solicit funding from individuals. Should you receive such requests apparently coming from IFCN, please do not respond to the sender, and instead notify the IFCN HQ office.
