Abstract :
In this study, a multi-segment foot motion analysis on hallux valgus patients were performed using the 9-segment foot model and then compared with the results from normal subjects. Results showed that there were no significant differences in hindfoot motions between normal subjects and HV patients. However, noted in HV patients were hyper-external rotation in the talocrural joint, an excessive eversion of the subtalar joint during early stance and lack of dynamic motion in hallux MP and medial MP joints especially during terminal stance. In spite of limitation in this study due to the small number of HV patients, the current multi-segment foot model would be feasible to diagnose and treat patients with various foot diseases, combined with further studies in the future
