ABSTRACT
INTRODUCTION:
Duration of training to reliably measure nerve cross-sectional area with ultrasound is unknown.METHODS:
A retrospective review was performed of ultrasound data, acquired and recorded by 2 examiners-an expert and either a trainee with 2 months (novice) or a trainee with 12 months (experienced) of experience. Data on median, ulnar, and radial nerves were reviewed for 42 patients.RESULTS:
Interrater reliability was good and varied most with nerve site but little with experience. Coefficient of variation (CoV) range was 9.33%-22.5%. Intraclass correlation coefficient (ICC) was good to excellent (0.65-95) except ulnar nerve-wrist/forearm and radial nerve-humerus (ICC = 0.39-0.59). Interrater differences did not vary with nerve size or body mass index. Expert-novice and expert-experienced interrater differences and CoV were similar. The ulnar nerve-wrist expert-novice interrater difference decreased with time (rs = -0.68, P = 0.001).DISCUSSION:
A trainee with at least 2 months of experience can reliably measure upper limb nerves. Reliability varies by nerve and location and slightly improves with time. Muscle Nerve 57 189-192, 2018.Palavras-chave
