The minimum amount of change which represents clinical improvement following ankle sprains is unknown. This study considers the usefulness of physiological and behavioral measures commonly employed for this purpose in sports rehabilitation settings. Thirteen collegiate athletes of both genders were measured at approximately 3 and 10 days post-grade I or II ankle sprain. Volumetric displacement and sagittal plane ankle range of motion measures were used as impairment indicators. Motor ability scores (activity count) and a perceived athletic ability measure (visual analog scale) were used to indicate functional limitations. Volumetric displacement and both functional limitation measures demonstrated responsiveness to change between two occasions of measurement separated by 1 week. Observed changes in range of motion deficits could not be distinguished from measurement error. The results of this study suggest that behavioral measures of motor activity and perceived athletic ability may be at least as useful as physical measures of organic dysfunction for assessing clinical improvement following acute ankle sprains among athletes.
踝关节扭伤后代表临床改善的最小变化量尚不清楚。本研究探讨了体育康复环境中常用于此目的的生理和行为测量方法的实用性。对13名男女大学生运动员在I级或II级踝关节扭伤后约3天和10天进行了测量。体积位移和矢状面踝关节活动度测量用作损伤指标。运动能力得分（活动计数）和感知运动能力测量（视觉模拟量表）用于指示功能限制。体积位移和两种功能限制测量均显示出对相隔1周的两次测量之间变化的反应性。观察到的活动度缺陷变化与测量误差无法区分。本研究结果表明，对于评估运动员急性踝关节扭伤后的临床改善，运动活动和感知运动能力的行为测量可能至少与器质性功能障碍的物理测量同样有用。
