Muscle morphology of the gastrocnemius medialis in children with cerebral palsy and typically developing children

	CP	TD	Effect size
Fascicle length (cm)	3.4 (1.0)*	4.4 (0.8)	1.12
Fascicle length (normalized to MTU)	0.09 (0.02)**	0.11 (0.02)	1.31
Fascicle length (normalized to muscle belly length)	0.19 (0.04)	0.20 (0.03)	0.29
Pennation angle (°)	21.9 (2.9)**	18.1 (2.7)	−1.36
Muscle thickness (cm)	1.3 (0.4)	1.3 (0.2)	0.00

Values are reported in mean (standard deviation). CP cerebral palsy; TD typically developing; MTU muscle-tendon unit
