研究设计：回顾性研究。目的：评估恢复无限制活动的运动员的踝关节扭伤后的活动范围、距骨后滑移和残留关节松弛。背景：踝关节外侧扭伤是运动人群中的常见病，其再损伤率可高达80%。为了更好地了解再损伤的危险因素，对一组大学生运动员的损伤后遗症进行了评估。方法和措施：对12名在过去6个月内有踝关节外侧扭伤病史并重新参加运动的运动员进行测试。只有报告从未损伤过对侧脚踝的运动员才包括在内。对受试者受伤和未受伤的踝关节进行关节松弛、踝关节背屈活动范围和距骨后滑度的比较。用Friedman等级顺序检验分析关节松弛程度，用Manova评估背屈和距骨后滑脱测量。结果：损伤踝关节距小腿关节和距下关节松弛程度明显增加。在损伤和未损伤的踝关节之间的任何踝关节背屈测量没有显著差异，但损伤的踝关节与未损伤的踝关节相比，距骨后滑度显著减少。结论：在我们的样本中，踝关节外侧扭伤后普遍存在残留的韧带松弛。尽管有证据表明距小腿关节后方滑行受限，但研究人群的背屈活动范围已恢复。虽然恢复了生理活动范围，但残留的关节功能障碍仍然存在。需要进一步的研究来阐明踝关节外侧扭伤后关节运动学改变的作用。
Study Design: Retrospective study.Objective: Assess range of motion, posterior talar glide, and residual joint laxity following ankle sprain in a population of athletes who have returned to unrestricted activity. Background: Lateral ankle sprains occur frequently in athletic populations and the reinjury rate may be as high as 80%. In an effort to better understand risk factors for reinjury, the sequelae to injury in a sample of college athletes were assessed.Methods and Measures: Twelve athletes with a history of lateral ankle sprain within the last 6 months and who had returned to sport participation were tested. Only athletes who reported never injuring the contralateral ankle were included. The injured and uninjured ankles of subjects were compared for measures of joint laxity, ankle dorsiflexion range of motion, and posterior talar glide. Friedman's test of rank order was used to analyze the laxity measures and a MANOVA was used to assess the dorsiflexion and posterior talar glide measures.Results: Laxity was significantly greater at the talocrural and subtalar joints of the injured ankles. There were no significant differences in any of the ankle dorsiflexion measurements between injured and uninjured ankles, but posterior talar glide was significantly reduced in injured ankles as compared to uninjured ankles.Conclusion: In our sample of subjects, residual ligamentous laxity was commonly found following lateral ankle sprain. Dorsiflexion range of motion was restored in the population studied despite evidence of restricted posterior glide of the talocrural joint. Although restoration of physiological range of motion was achieved, residual joint dysfunction persisted. Further research is warranted to elucidate the role of altered arthrokinematics after lateral ankle sprain.
