Message from the IFCN President

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 Open Blog.

Clinical Neurophysiology Practice Journal

Volume 4 (2019) (Open access)

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.
