Exampled calibration and prediction performance on Participant Sub01 by using five HNM categories. The blue, red, orange, purple, and green bars represent the results by using the sEMG-, US imaging-, sEMG-US imaging-, random signal (RS)-, and sEMG-RS-driven HNMs under both single-speed modes and inter-speed mode. (a) Calibration RMSE and prediction RMSE values under different speed modes. (b) Calibration R-square and prediction R-square values under different speed modes. Figure S19. Exampled results of the ankle joint net moment and processed sEMG signals from LGS, MGS, SOL, and TA muscles throughout the recorded walking duration. Data are collected during the treadmill walking experiments on Sub01, where muscle activation levels from LGS and MGS muscles are comparable, and the activation level of the TA muscle is relatively small during the walking stance phase. (a) Walking speed at 0.5 m/s. (b) Walking speed at 0.75 m/s.
