Fig 6. Peak joint angles at maximal platform displacement for young and older models, and all cases of strength loss.

The top of the bars indicate peak ankle plantar flexion/hip flexion angle, and the bottom of the bars indicate peak dorsiflexion/hip extension angle. The total height of the bars indicate the range of ankle and hip joints used. Note the difference in range between the ankle (left) and hip (right) y-axes. The percentages at the bottom represent the percent reduction in maximal platform displacement compared to the young model.
