Square Drawing Tests (SDT) for detecting and evaluating ataxic disorders were designed by Sekitani (1974), a modification of Fukuda's vertical writing test.
The purpose of this paper is to describe the procedures of tests by each hand bimanual SDT; abbreviated to B-SDT and by both hands at one time (simultaneous bimanual SDT; abbreviated to SB-SDT); and to present the results obtained from the 100 healthy adults.
The basic parameters of these tests and their results are as follows :
1. Length of each line of square drawn with eyes open and with eyes closed is measured. In this group of healthy adults, there was a gradual shortening of length in each line of the square drawn after the first square.
2. Distance between the starting point and the end point of each square (Distance S-E), showed a gradual enlargement in the square aftar the first square; especially when the square was drawn with the left hand.
3. Distance between the starting point of No.1 square and the starting point of No.4 square in B-SDT (or between that of No.2 and of No.4 square in SB-SDT) (Distance 1-4, so-called “whole length”); showed in this group a shortening of the entire length with the eyes closed as compared to that seen with the eyes open. There was no marked difference in the entire length between the data obtained with drawing done with the right hand and with the left hand in SB-SDT.
4. Deviation angle of the square to the vertical line; showed some tendency to deviation rightward in both B-SDT and SB-SDT, but a deviation over 7 on the average, was not seen.5. Derangement of the drawn lines : Derangement of the drawn lines in the group of 100 healthy adults was evident in only one subject. There was no tendency toward increase in derangement with the eyes closed.
These results suggest no marked differences of each square between eyes open and closed, between right hand and left hand.
