The presence of sensorimotor deficits in patients who have suffered ankle sprains or who have chronic ankle instability has been recognized for several decades; however, a body of research literature has developed that elucidates potential physiologic explanations for these deficits. Alterations in a spectrum of sensorimotor measures make it apparent that conscious perception of afferent somatosensory information, reflex responses, and efferent motor control deficits are present with ankle instability. The specific origin of these deficits local to the ankle ligaments or at the spinal or supraspinal levels of motor control have yet to be fully elucidated. It is clear, however, that both feedback and feedforward mechanisms of motor control are altered with ankle instability.
踝关节扭伤或患有慢性踝关节不稳的患者存在感觉运动功能障碍，这一情况已被认识数十年；然而，现在已形成了一批研究文献，阐明了这些功能障碍潜在的生理学解释。一系列感觉运动测量指标的改变表明，踝关节不稳时存在对传入躯体感觉信息的意识感知、反射反应以及传出运动控制功能障碍。这些功能障碍在踝关节韧带局部，或在运动控制的脊髓或脊髓上水平的具体起源尚未完全阐明。然而，很明显，运动控制的反馈和前馈机制在踝关节不稳时均发生了改变。
