In order to evaluate age-related hand coordination, quantitative analysis of ability to track moving targets by the use of ECG machine was carried out on healthy aged subjects containing 36 males and 34 females, whose age ranged from 66 to 91 with the mean of 78.2 years. Then, the above data were compared with simultaneously obtained aging score (by AMAKO), one leg standing time with eyes closed (standing time), dementia rating (D. R.) score and ability to keep short term memory (memory score) obtained from HASEGAWA's D. R. scale. The results were as follows, 1) Ablity to track the moving targets was significantly decreased with aging. 2) With aging, aging score increased and standing time shortened significantly, while D. R. score tended to decline. 3) There was no significant correlation between ability to track moving targets and D. R. score. 4) Ability to track moving targets was significantly correlated with not only memory score but standing time.
