Performance on motor tasks

Descriptive statistics for performance on the PANESS and the finger-sequencing task completed inside and outside of the scanner. Children with ADHD displayed increased hand-related overflow on the PANESS and greater total overflow during the finger sequencing tasks completed outside of the scanner. Typically developing controls demonstrated faster tap speed during the finger-sequencing task completed inside of the scanner as indicated by a greater number of finger taps during the 45-s blocks.

	Controls	ADHD	p-value
PANESS total score	19.8(6.8)	30.6(11.2)	0.002
PANESS total hand-related overflow	3.1(2.2)	6.7(4.1)	0.003
Finger sequencing task (out of scanner) total overflow	390 (243)	726 (500)	0.016
Finger sequencing task (in scanner)
Total fingertaps RHFS	514 (99)	441 (76)	0.028
Total fingertaps LHFS	504 (98)	422 (77)	0.019

Note: Values represent mean (SD). PANESS = Physiological and Neurological Examination for Subtle Signs; RHFS = right-hand finger sequencing; LHFS = left-hand finger sequencing.
