Correlation between co-activation and gait speed in stance phase. The trunk part CI revealed a significant positive partial correlation with gait speed (RA:ES, r = 0.454, p = 0.002; RA:MF, r = 0.663, p < 0.001). However, significant negative partial correlations were found between the thigh part CI and gait speed (RF:BF, r = -0.322, p = 0.032; VMO:BF, r = -0.446, p = 0.002; GMED:ADD, r = -0.615, p < 0.01). RA: Rectus abdominis, ES: Erector spinae, MF: Multifidus, RF: Rectus femoris, BF: Biceps femoris, VMO: Vastus medialis oblique, GMED: Gluteus medius, ADD: Adductor longus
