Impaired proprioception has been suggested as one cause of chronic lateral instability of the ankle. We subjected 15 ankles in 13 patients with symptoms of chronic lateral instability to sudden angular displacement. The reaction times in the peroneus longus and the tibialis anterior muscles were recorded and compared with those from 15 control ankles. Significantly longer ipsilateral reaction time was recorded in the patients (65 ms) compared with the controls (49 ms). We concluded that delayed proprioceptive response to sudden angular displacement of the ankle may predispose an individual to or be a cause of chronic lateral instability of the ankle.
本体感觉受损被认为是踝关节慢性外侧不稳定的一个原因。我们对13例有慢性外侧不稳定症状患者的15个踝关节进行了突然角位移测试。记录了腓骨长肌和胫骨前肌的反应时间，并与15个对照踝关节的反应时间进行比较。与对照组（49毫秒）相比，患者患侧的反应时间明显更长（65毫秒）。我们得出结论，踝关节突然角位移时本体感觉反应延迟可能使个体易患踝关节慢性外侧不稳定或成为其病因。
