The A. investigates the development of asymmetries in the upper extremity in relation to age and sex, to differentiate fluctuating and directional asymmetry and to define the borderlines of physiological and non-physiological asymmetries in different traits. Asymmetries of the upper extremities were analyzed in 1,002 children from Prague, Czech Republic, aged 6-18 years. The length of the upper extremity upper arm, forearm and hand, circumference of the arm, forearm and wrist and width of the epiphysis of the humerus, wrist and hand were assessed. Left-handed subjects were excluded from the study. The results revealed that the degree of asymmetries of the upper extremity is equal in both sexes and does not change substantially with age (absolute asymmetry increases in direct relation to the growth of the trait).
