Abstract
This study aimed to quantify the differences in the control strategies of ankle muscles between symptomatic pronators (SP) and asymptomatic pronators (AP) during running. Thirty participants were measured by a motion capture system and a surface electromyography device. Results showed that the SP and AP had different muscle-tendon unit length changes during the swing phase, with the SP having less shortening of the soleus and peroneus longus (up to 3.6 mm and 4.0 mm, respectively), faster lengthening of the plantar flexors (up to 80.4 mm/s) but larger (up to 5.7 mm) and faster (up to 46.2 mm/s) shortening of the tibialis anterior. The SP also showed a lower median frequency of the soleus than the AP. These results indicated the different ankle muscle control between them, which might provide new insights into the understanding of pathology of the SP.
