Abstract


Purpose: To investigate the alteration of lower extremity movement during maintaining balance test with their eyes closed in chronic ankle instability (CAI) patients compared to healthy group with and without plantar cutaneous sensation.

Methods: Ten healthy volunteers (age, 23.40±2.22 years; height, 165.42±6.67 cm; weight, 60.93±13.42 kg) and 10 CAI patients (age, 23.90±2.56 years; height, 166.89±10.50 cm; weight, 67.43±12.96 kg), were recruited. Subjects immersed both feet in an ice water for 10 minutes and performed three trials of a single-leg stance balance test with their eyes closed while standing on a force plate for 10 seconds.

Results: CAI group showed increased knee flexion, reduced knee external rotation, and hip internal rotation compared to the healthy group from single-limb stance with eyes closed after diminished plantar cutaneous sensation. However, there was no significant interaction between group and time.

Conclusion: These findings indicate that the postural kinematic analyses revealed that individuals with CAI used different strategy of controlling their lower extremities, which alters transverse plane motion of hip and knee compared to the healthy group in order to compensate for their ankle deficits after freezing the plantar cutaneous.
