Studying the effect of parkinsonism on handwriting

ABSTRACT

Handwriting is an acquired skill. It is one of the most important parameters of the personal identification. It involves muscular actions and reflexes. There must be canstant coordination between the wrist and the arm muscles. Diseases of the CNS such as Parkinsonism can exhibit some interventions, which interfere with the process of writing. This work aimed at studyingg the effect of Parkinsonism on the handwriting via comparing the handwriting of the same person both before and after the disease from different technical points of view. The statistical results were found to be highly significant, also there was found to assume that the severer the disease, the more marked is the effect on the handwriting and the more the statistical significance. This is due to the effect of Parkinsonism on CNS, and on the musculoskeletal system involved in the process of handwriting
