Figure 4. The mean knee abduction moment curves for a) the varus group without a toe clip, b) the varus group with a toe clip, c) the neutral group without a toe clip, d) the neutral group with a toe clip, e) the valgus group without a toe clip and f) the valgus group with a toe clip. The dotted line is for 0.5 kg workload, the solid line is for 1.0 kg workload, and the bold line is for 1.5 kg workload. Abduction moment is negative.
