The masses and inertial properties of the mouse torso and hindlimb segments used to simulate trotting in the hindlimb.

Segment	Mass (g)	Center of mass (mm; x, y, z)	Moments of inertia (kgm2; xx, yy, zz)
Torso	19.5	29.4	1.07 × 10−6
		−4.1	9.43 × 10−6
		−1.5	9.12 × 10−6
Pelvis	0.38	2.9	2.35 × 10−9
		−1.2	6.43 × 10−9
		2.4	6.70 × 10−9
Thigh	0.44	−2.8	6.83 × 10−9
		−7.2	4.23 × 10−9
		0.20	9.10 × 10−9
Lower Leg	0.21	−0.8	3.73 × 10−9
		−7.2	6.80 × 10−10
		0.0	4.10 × 10−9
Foot	0.063	4.5	6.10 × 10−11
		−0.20	1.26 × 10−9
		0.10	1.26 × 10−9

Center of mass values are shown with respect to the coordinate system origins (i.e., proximally) of each segment (see Charles et al., 2016b for more details). + x, cranial; + y, proximal (dorsal); + z, lateral. See Figure 4 for how the segments were partitioned.
