[A dexterity test in school-age children].

: In a group of 50 children of school age a dexterity test was performed. The group comprised children who, when born, were mature, immature or hypotrophic. The authors describe the method of the test, its physiological background and value. From the results of the test ensues that there is no difference between boys and girls, no difference in practice and gnosis, no difference between the right and left hand, the result of the test does not depend on age. Maturity, prematurity or hypotrophy caused significant differences in the results of the test. As according to statistical criteria the group is sufficiently numerous, the submitted results of the test can be used as standards in school children who were born mature, premature or hypotrophic. The submitted battery of tests is a suitable method for testing of dexterity. In the conclusion the authors give output data for paediatric and teaching practice.
