Fig. 5

Boxplot graphics shows mean lateral deviation calculated as the root mean square while walking A and surface rotation B in subjects with LLI < 2 cm (blue) and LLI ≥ 2 cm (red). Stance phases of one gait cycle are listed on the x-axes: initial contact of the foot touching the ground (t0), mid-stance when the whole foot has contact (t1) and the terminal contact phase before the foot lifts off the ground (t2). Lateral deviation and surface rotation show orientation to the longer leg, which is indicated by positive values
