Abstract

Background: An unstable ankle along with plantar flexor muscle fatigue may exacerbate landing performance. External support may be an option to control the ankle motion and protect joints from injuries. Research goal: To investigate the immediate changes in the joint motion of a lower extremity under ankle plantar flexors fatigue conditions in athletes with unstable ankles using different external supports. Methods: A total of 44 participants were allocated to a control (Cn) group, an ankle brace (AB) group, and a kinesio tape (KT) group, and were asked to perform a lateral drop landing before and after a fatigue protocol. The outcome measures were fatigue-induced changes in the maximal joint angle and changes in the angle ranges of the hip, knee, and ankle. Results: Smaller changes in the maximal hip abduction were found in the AB group ( p = 0.025), and the KT group exhibited smaller changes in the maximal ankle dorsiflexion ( p = 0.009). The AB group landed with a smaller change in the range of hip flexion and knee flexion ( p = 0.008 and 0.006). The Cn group had greater fatigue-induced changes in the COM range than AB and KT group ( p = 0.002 and 0.028). Significance: Despite the beneficial effect in the postural control in the frontal plane, the use of AB might constrain the distal joint motion which might lead to an extended knee landing posture resulting in secondary injuries to the knee joint. Therefore, the use of AB in conjunction with an additional training of landing strategy might be recommended from the injury prevention perspective.
