 In gait analysis, comparing knee joint angles across three walking speeds (SLOW, MEDIUM, FAST) might use three separate groups (one per speed condition). Each group would contain two conditions: left knee angle time-normalized from left heel strike (LHS)-LHS and right knee angle from right heel strike (RHS)-RHS, both refined by the appropriate speed tag. This structure enables direct comparison across speed conditions while properly handling bilateral symmetry within each condition. In gait analysis, comparing knee joint angles across three walking speeds (SLOW, MEDIUM, FAST) might use three separate groups (one per speed condition).
