| Popis: | Motor unit number index (MUNIX) of the upper trapezius is a candidate biomarker for lower motor neuron function of the bulbar region; however, only a few studies have explored this measure in neuromuscular diseases and reliability data is incomplete. We conducted a systematic review and meta-analysis of this measure in control participants and assessed its reliability in twenty healthy volunteers. Four studies were included with heterogeneous mean-MUNIX estimates, moderated by variability in the population’s age and MUNIX sampling technique. We demonstrated an inter- and intra-rater intraclass correlation of 0.86 and 0.94, respectively. Upper trapezius MUNIX is a reliable measure with in-between study variability moderated by age and MUNIX technique. |
