The values in italics are statistically significant.

a

RMSDs in ankle, knee and hip joints, and the sum of these, are expressed as the percentage of mean force from the subject-specific model.

b

Difference in gender is defined as 1 or 0.

c

Difference in anthropometry measurements is expressed as a percentage difference from the underlying dataset to the subject; pelvis width is defined as the distance between right and left anterior superior iliac spine; the limb length to pelvis width ratio (ratio) is defined as limb length divided by pelvis width.
