Change in Assessment of Motor and Process Skills (AMPS) scores (logits) during the intervention period

AMPS Variable	Preintervention	Postintervention	Change from pre- to postintervention	Effect size	P value
Motor score	1.34 (0.68)	1.74 (0.43)	0.51 (0.54)	0.74	.0093
	1.39 (0.37; 2.60)	1.79 (1.11; 2.32)	0.69 (-0.73; 1.05)
	(0.93; 1.75)	(1.46; 2.01)	(0.16; 0.85)
	n=13	n=12	n=12
Process score	0.83 (0.51)	1.36 (0.36)	0.50 (0.37)	1.43	.0020
	0.66 (0.21; 1.87)	1.31 (0.86; 1.89)	0.54 (-0.23; 1.03)
	(0.53; 1.14)	(1.13; 1.59)	(0.27; 0.74)
	n=13	n=12	n=12

The evaluations immediately before and after the intervention period were used for both randomization groups. Variables are presented as Mean (SD) / Median (Min; Max) / (95% CI for mean). Effect size expressed as Standardized Response Mean.
