Influence of Age, Gender, and Sidedness on Ulnar Nerve Conduction

Anatomic variation and susceptibility for injuries depending on gender were described for the ulnar nerve. The aim of this study was to investigate the association between gender and ulnar never motor conductance and the influence of sidedness for this association. Study was conducted as a retrospective study using nerve conduction study data of ulnar nerve of 2,526 patients. Influences of age, gender, and sidedness on ulnar never motor conduction velocity (UMV) were investigated. Regression analysis was conducted to compare the relationship between UMV and age. Regression was significantly higher in males (-0.253 vs. -0.113), suggesting higher influence of age on UMV in males than in females. When analyzing right and left sides separately, influence of age on UMV is higher in males (-0.286 vs. -0.109) only in right side. Multiple regression analysis was done comparing the influence of age, gender, and sidedness on UMV, and it found that the order of influence is gender, age, and sidedness (Beta values 0.153, -0.140, and 0.029). Ulnar nerve motor conductance depends on gender, age, and sidedness. Males are having lower UMV than females. Age-dependant change of UMV is more prominent in males than in females and is more prominent in right hand than in left hand in males.
