Quality Control of Motor Unit Number Index (MUNIX) Measurements in 6 Muscles in a Single-Subject Round-Robin Setup

摘要

BackgroundMotor Unit Number Index (MUNIX) is a neurophysiological measure that provides an index of the number of lower motor neurons in a muscle. Its performance across centres in healthy subjects and patients with Amyotrophic Lateral Sclerosis (ALS) has been established, but inter-rater variability between multiple raters in one single subject has not been investigated.
