Ultrasound of median and ulnar nerves in the distal arm of healthy volunteers- inter- and intra rater reliability

Objective: The aim of this study was to investigate the intra-and inter-rater test-retest reliability of the cross sectional areas of the median and ulnar nerves measured by high frequency ultrasound in the distal arm of healthy volunteers. Materials and methods: Intra-rater reliability study: 19 healthy volunteers, mean age 33 (range 21 – 68) (15 females) were recruited and ultrasound measurements of median and ulnar nerves were performed twice bilaterally by one examiner (EQ) with an interval of one week apart and at the same time of the day in a blinded fashion. Inter-rater reliability study: 10 healthy volun…
