Evaluation of the Effect of Age on Median Nerve Cross-sectional Area: A Cross-sectional Study

doi:10.37015/AUDT.2023.220047

Abstract

Abstract:

Objective This cross-sectional study was designed considering disagreements on the normal range of Median Nerve Cross-Sectional Area (MNCSA) and its association with age.

Methods In this cross-sectional descriptive study, the upper limbs of 98 healthy subjects (46 men and 52 women) were assessed bilaterally by sonography, and MNCSA was measured at the distal wrist crease.

Results Mean MNCSA values for subjects older and younger than 40 were 11.25 mm² and 10.21 mm², respectively. The results showed that the MNCSA significantly increased after 40 years of age.

Conclusion According to the present study's findings, advances in age can increase the MNCSA and affect the diagnostic accuracy of MNCSA measurement in CTS diagnosis.

Key words: Median nerve cross-sectional area; Sonography; Age
