The first objective of this study was to identify the deformation of the median nerve cross-sectional area (MNCSA) at different wrist active and passive holding positions. The second objective was to compare the wrist circumference, wrist width, and wrist depth between dominant and non-dominant hands. A total of eight right-handed healthy male adults (age 27.0 ± 3.5 years) participated in this study. Ultrasound examination was performed at the proximal carpal tunnel to examine the median nerve on the transverse plane. A total of three wrist positions were examined, namely, wrist neutral, wrist flexion 30°, and wrist extension 30°, in active and passive holding positions for both dominant and non-dominant hands. Paired t-test showed significant differences between dominant (D) and non-dominant (ND) hands in wrist circumference (D = 15.9 ± 0.6 cm, ND = 15.7 ± 0.6 cm, p<0.05), wrist width (D = 56.3 ± 3.6 mm, ND = 54.0 ± 2.1 mm, p<0.05), and wrist depth (D = 39.6 ± 2.8 mm, ND = 38.3 ± 2.7 mm, p<0.01). The differences of MNCSA between dominant and non-dominant hands were significant (p<0.001) at both active (D = 7.93 ± 0.63 mm<SUP>2</SUP>, ND = 6.98 ± 0.42 mm<SUP>2</SUP>) and passive holding positions (D = 8.22 ± 0.72 mm<SUP>2</SUP>, ND = 7.06 ± 0.44 mm<SUP>2</SUP>). Two-way repeated-measures ANOVA showed that wrist flexion 30° and wrist extension 30° caused significant reductions in MNCSA when compared with wrist neutral (p<0.001) in both active and passive holding positions. However, wrist active and passive holding did not have a significant effect on MNCSA changes. In conclusion, our findings showed that significant reduction of MNCSA was associated with wrist flexion-extension motion and there was significant bilateral asymmetry in physical characteristics of the wrist.
