If ankle proprioception can be determined to be impaired, then treatment can be more specifically directed toward correcting the proprioceptive deficit, thereby improving functional ability. The purpose of this study was to determine if collegiate level gymnasts with unilateral, multiple ankle sprains (ie., chronic ankle sprains) had decreased ability to detect passive plantar flexion of the ankle (ie., decreased ankle proprioception) and to determine if balance deficits existed during one-legged stance. Eleven gymnasts participated in 30 passive movement trials (15 movement and 15 nonmovement) presented randomly on both the injured and noninjured sides. The nonmovement trials consisted of either no movement of the ankle or passive movement of the ankle into 5 degrees of plantar flexion. Luce's choice theory determined that subjects were not biased in responding to a "yes" in perceiving movement or no movement during the movement/nonmovement trials of passive plantar flexion. Subjects were better able to detect movement during movement trials with their uninjured ankles than their injured ankles. Subjects also performed single 30-second trials of one-legged standing on each leg, with eyes open and with eyes closed. Subjects reported better balance when standing on the uninjured ankle during the one-legged stance conditions. Although our results cannot be extrapolated to balance abilities during complex gymnastic routines, they do suggest that physical therapy assessment includes passive detection of joint position as well as single-legged stance tests, and that perhaps rehabilitation programs incorporate sports-specific balance activities for such injuries.
如果能够确定踝关节本体感觉受损，那么治疗就可以更有针对性地纠正本体感觉缺陷，从而提高功能能力。本研究的目的是确定患有单侧、多次踝关节扭伤（即慢性踝关节扭伤）的大学水平体操运动员检测踝关节被动跖屈的能力是否下降（即踝关节本体感觉下降），并确定单腿站立时是否存在平衡缺陷。11名体操运动员参与了30次被动运动试验（15次运动试验和15次非运动试验），试验在受伤侧和未受伤侧随机进行。非运动试验包括踝关节不运动或踝关节被动跖屈5度。卢斯选择理论确定，在被动跖屈的运动/非运动试验中，受试者在感知运动或无运动时对“是”的反应没有偏差。与受伤的踝关节相比，受试者在使用未受伤的踝关节进行运动试验时，能更好地检测到运动。受试者还分别对每条腿进行了单腿站立30秒的试验，试验时眼睛睁开和眼睛闭上。受试者报告说，在单腿站立状态下，用未受伤的踝关节站立时平衡更好。虽然我们的结果不能外推到复杂体操动作中的平衡能力，但它们确实表明，物理治疗评估包括关节位置的被动检测以及单腿站立测试，并且康复计划可能需要纳入针对此类损伤的特定运动平衡活动。
