| Objective: To explore the correlation between hip and ankle muscle strength, ankle dorsiflexion and dynamic and static balance of both lower limbs in patients with unilateral chronic ankle instability (CAI), as well as the differences between unaffected and affected sides. Methods: Totally, 36 patients with CAI were collected for hip and ankle muscle strength evaluation, static and dynamic balance test and ankle dorsiflexion measurement. Results: Static balance was mainly related to the strength of ankle muscle group (P<0.05), and dynamic balance was related to strength and ankle dorsiflexion of hip and ankle muscle group (P<0.05). There was no significant difference in strength of static balance and hip muscle group on the unaffected side (P>0.05), but there was significant difference in dynamic balance, ankle muscle group strength and ankle dorsiflexion (P<0.05). Conclusion: There are differences in the correlation between static balance and dynamic balance, which provides different guidance directions for the improvement of dynamic and static balance. At the same time, the function of the unaffected side of CAI patients is similar to that of the affected side, suggesting that the unaffected side may be damaged and can’t be ignored in rehabilitation. |
