TABLE 3.

The height of the pelvis ACS origin relative to the ground in each of the continuum motions at 50% of the stance phase. All heights were calculated using trigonometry

Motion	Distance from pelvis to ground (mm)
High walk	106.3 mm
Crouched walk	98.6 mm
Bended walk	104.1 mm
Sprawl v1	70.3 mm a
Sprawl v2	69.4 mm a

^a Whilst the sprawling behaviours indicated that the pelvis to ground distance was comparably similar between these trials (i.e. ~1 mm difference in pelvic height), inspection of the joint ROMs determined that femoral protraction slightly varied between these trials (i.e. femoral retraction was greater in sprawl v2 than sprawl v1—see Table 5 and text) and thus they were separated in this study to determine if any differences existed when femoral protraction differed.
