(1)Kinesia score (KS): the number of keystrokes in 60  seconds
(2)Akinesia time (AT): the cumulative time that the keys are  depressed for longer than 17 ms
(3)Inco-ordination score (IS): a measure of rhythmicity, which   corresponds to the variance of the time interval between keystrokes
(4)Dysmetria score (DS): a weighted index calculated using  the number of incorrectly hit keys corrected for speed
