Fig. 1 One-way MANOVA on the data in the figure during stance phase of stair descent. The χ2 trajectory exceeded the threshold for significance over approximately 0–10% of the stance phase, implying differences amongst the three groups. The p value indicates the probability with which Gaussian random fields, with the identical smoothness as the model residuals, would produce a supra-threshold cluster of the same temporal extent.

Fig. 3 Post hoc analyses of the results in the figure, comparing the ACLPT group to the controls for (a) flexion/extension, (b) adduction/abduction, and (c) internal/external rotation during the stance phase of stair descent.

Fig. 4 Mean planar trajectories and standard deviation clouds for the Control and ACLPT (Non-surgery) groups during the stance phase of stair descent, as an exploration of the figure results. Positive values indicate (a) flexion, (b) adduction and (c) internal rotation respectively.
