Fig. 2.

Mean hip, knee, and ankle joint moment of force time series across all participants in each of the three clusters detected from the clustering analysis of the first DVJ trial. Each waveform represents the mean external joint moment of force for the specified DOF, and the arrows indicate the interpretation convention for each moment. For DOF with an active joint torque mechanism (e.g., the hip in all three planes, the knee in the sagittal plane, and ankle in the sagittal plane), they are interpreted as internal moments of force, which correspond with the absolute magnitude of the moment. For example, external knee flexor moment is negative, so a higher internal knee extensor moment is interpreted as a more negative moment. Shaded regions indicate standard error regions between the groups.
