Electromyography activity during primary torque and secondary torque generation. An asterisk denotes statistical significance between conditions (**; p < 0.01, *; p < 0.05). A, In the control group, the gastrocnemius and soleus activities during PTo were higher than those during STo. B, In subjects after stroke, the tibialis anterior activity during STo was higher than that during PTo.
