Figure 2. Prediction for a random limb (knee flexion) and contribution of each surgical model. Green dotted line corresponds to the preoperative curve, blue dash-dotted line is the prediction and red dashed line is the postoperative curve. The black line with the grey band corresponds to the standard gait signal (mean ± 2 standard deviations). Lines with markers correspond to contributions surgical procedures (5 procedures in this example).
