Abstract:
Objective:To explore the effects of whole-body fatigue on the balance and ankle proprioception during drop landing of individuals with functional ankle instability(FAI)by comparing the differences in balance and pro-prioception between the FAI group and the control group before and after fatigue. Method:A total of 31 participants with unilateral FAI and 31 healthy participants were included in this study.A static balance test,dynamic balance test,and ankle proprioception test were conducted before and after fa-tigue.Sway distance(D)of the center of pressure(COP),root mean square of the COP(RMS),95％confi-dence ellipse area of the COP movements(95％AREA),normalized reach distance,and the area under the curve(AUC)were calculated and analyzed. Result:Before whole-body fatigue,the static balance,dynamic balance,and ankle proprioception during drop landing in FAI group were significantly lower than those in control group.After whole-body fatigue,the static balance,dynamic balance,and ankle proprioception during drop landing in the FAI group and control group decreased significantly(P＜0.05),and the increase of D,RMS and 95％AREA in FAI group were significant-ly larger than those in control group(P＜0.05),and the decrease of normalized reach distance in the postero-medial and posterolateral directions and AUC were significantly larger than those in control group(P＜0.05). Conclusion:Whole-body fatigue reduced the static balance,dynamic balance,and ankle proprioception,and the reduction was larger in FAI individuals than in healthy individuals.Therefore,whole-body fatigue may in-crease the risk of recurrent ankle sprain by reducing posture control and proprioception in FAI individuals.
