| Research Abstract |
In order to analyze cerebellar ataxia of the upper limbs writing of the letters and/or figures was evaluated by the use of a digitizer. In 1997 the digitizer to be designed to check the specificity of the pen pressure written by the graphic pen could be utilized to demonstrate the fundamental characteristics to be visualized on the display to reveal the graphic pressure computerized through the digitizer. In reference to the relationship of input to output of the graphic pen, the pen touch could be adjusted to be set step by step so as to keep the record of the description. However the continuous record of the description written by the graphic pen was impossible and the pressure of the pen stroke was unable to be consistently recorded with the calligraphy. The computer is expected to be programmed to memorize the absolute value of the graphic pressure along with the calligraphy.
In 1998 the projects to visualize the calligraphy skillfully written by healthy people and to prove the loss f the skills in the ataxic patients on the computer display was undertaken. The development to realize the program is still in progress.
Another research project to be performed by Doctor Shinichi Yanagimoto et al on evaluation of ataxia of the upper limbs in 1998 is to let the ataxic patients trace the depicted lines and circles and to memorize the deviated areas on the computer. The test to trace the depicted line demonstrated remarkable increase of deviation at the terminal of the line.
