Figure 8

Interpreting the contributions of EMG features to estimate the knee OA severity, as demonstrated in the SHAP Summary plot, with a focus on (a) WOMAC total, (b) WOMAC pain, (c) WOMAC stiffness, (d) WOMAC physical function, and (e) VAS scores, ranked by importance. CCI: CCI: co-contraction index, RF: rectus femoris, MH: medial hamstring, TA: tibialis anterior, G: gastrocnemius, A: Average, MAX: maximum, MIN: minimum, ST: stance phase, SW: swing phase, T: time latency, AUC: area under the curve; VAS: visual analog scale; WOMAC: Western Ontario and McMaster Universities Osteoarthritis index; EMG: electromyography.
