The purpose of this investigation was to determine the effect of different types of ankle sprains on the response latency of the peroneus longus and peroneus brevis to an inversion perturbation, as well as the time to complete the perturbation (time to maximum inversion). To create a forced inversion moment of the ankle, an outer sole with fulcrum was used to cause 25 degrees of inversion at the ankle upon landing from a 27 cm step-down task. Forty participants completed the study: 15 participants had no history of any ankle sprain, 15 participants had a history of a lateral ankle sprain, and 10 participants had a history of a high ankle sprain. There was not a significant difference between the injury groups for the latency measurements or the time to maximum inversion. These findings indicate that a previous lateral ankle sprain or high ankle sprain does not affect the latency of the peroneal muscles or the time to complete the inversion range of motion.
本研究的目的是确定不同类型的踝关节扭伤对腓骨长肌和腓骨短肌对内翻扰动的反应潜伏期以及完成扰动的时间（达到最大内翻的时间）的影响。为了产生踝关节的强迫内翻力矩，使用带有支点的外底，使参与者在从27厘米的下台阶任务落地时踝关节产生25度的内翻。40名参与者完成了该研究：15名参与者没有任何踝关节扭伤史，15名参与者有外侧踝关节扭伤史，10名参与者有高位踝关节扭伤史。在损伤组之间，潜伏期测量或达到最大内翻的时间没有显著差异。这些发现表明，先前的外侧踝关节扭伤或高位踝关节扭伤不会影响腓骨肌的潜伏期或完成内翻运动范围的时间。
