A comparative cross-sectional design study with a nonprobabilistic sampling with 50 women and 50 men in good health were submitted for measuring MNCSA at the level of the CT. Other variables like sex; side and degree of daily hand activity were also studied. The analysis was made by descriptive statistics, and Mann-Whitney U or Kruskal-Wallis tests. The mean MNCSA was 0.063 +/- 0.015 cm(2), in women; in men it was 0.072 +/- 0.018 cm(2); the difference was significant (p < 0.004). The median MNCSA among women was 0.062 cm(2) in the right side and 0.060 cm(2) in the left (90th percentile for both hands of 0.084 cm(2)); in men, it was of 0.070 cm(2) in the right hand and of 0.069 cm(2) in the left (90th percentile for both hands of 0.097 cm(2)). The difference between women and men was significant in each side, but not between right and left hands (p = ...
