Group	Age (years)	Gender (female/male)	LQ	Sports/week (hours)	Fine-motor training/week (hours)
MVFDH n = 16	26.56 ± 0.91	9/7	87.75 ± 4.17	2.84 ± 0.45	0.22 ± 0.19
MVFNDH n = 16	27 ± 1.30	10/6	88.63 ± 4.32	3.09 ± 0.48	0.06 ± 0.06

LQ, Laterality Quotient as assessed with the Edinburgh Handedness Scale [range: −100 (full left-handed) to + 100 (full right-handed)]. Hours of sports per week and hours of fine-motor training per week (e.g., playing a musical instrument, knitting, doing handcrafts, playing videogames with keypad or joystick) were assessed with a questionnaire. All values are depicted as mean ± standard error (SE) of the mean. Statistical analysis revealed no differences in age, gender, LQ, sports/week, fine-motor training/week between groups.
