Some factors contributing in graphomotor performance

Abstract

The aim of this paper is to explore the influence of neuromuscular maturity on the performance quality of graphomotor activity. The sample of 163 children (Mean=7,3 years, SD= 1,25), took tests to assess the quality of graphomotor performance. Tests required good and coordinated activity of a number of the muscles of the hand and of the fingers, visual motor control ad spatial orientation. Within the observed sample more than half (N=90, 55%) of the examinees manifested the muscle hypotonia and therefore, we can assert that at this age it represents a result of a process of maturation neuromuscular structure. Decreased muscle tonus was mostly manifested through numerous movements and interaction of the muscles indicating poor muscle differentiation, especially in case of the children with a muscule hypotonia (N=90). The quality of performed graphomotor activities was as expected at this age; children with a normal muscle tonus had a higher mean and proved to be more successful on tasks then children with a muscule hypotonia. The results point out the necessity for developing and practicing fine motor movements of a hand and fingers even at a preschool age. Through guided activities which will encourage fine motor coordination, it will be possible to achieve better differentiation and to create preconditions for easier mastering of the writing techniques.
