The time evolution of the postural behavior of 23 lateral ankle sprain patients (degrees I and II) were evaluated 14 h and 10 and 30 days on average after their injury and compared with those of 30 age-matched healthy individuals. The patients were tested with separate measurements of the reaction forces under each limb to highlight the possible compensatory mechanisms between the sound and the injured legs. Their postural behavior in bipedal stance was characterised by a weight-bearing asymmetry with more weight on the sound leg and an asymmetry of the postural stabilisation mechanisms, which are limited and perturbed under the injured leg. Pain appears to be the main factor for explaining these postural asymmetries. Despite these asymmetries, the patients were nonetheless more unstable than the individuals constituting the group control. Ten days later, only the weight-bearing asymmetry was still observed whereas 30 days later, the postural behavior was totally normal once again. Lateral ankle sprain perturbs the contribution of the injured leg in postural stabilisation, inducing a larger involvement of the sound leg in the postural stability process. These characteristics are largely reduced 10 days after the injury.
23 例Ⅰ级和Ⅱ级外侧踝关节扭伤患者（平均分别为损伤后 14 小时和 10 天及 30 天）的姿势行为时间演变情况进行了评估，并与 30 名年龄匹配的健康个体进行了比较。患者的每条肢体的反应力分别进行了单独测量，以突出健康和受伤腿之间可能存在的代偿机制。他们的双足站立姿势行为表现为承重不对称，即健康腿承重更多，姿势稳定机制的不对称性受到限制和干扰。疼痛似乎是解释这些姿势不对称的主要因素。尽管存在这些不对称性，但与对照组个体相比，患者的不稳定性更大。10 天后，仅观察到承重不对称性，而 30 天后，再次完全恢复正常的姿势行为。外侧踝关节扭伤会干扰受伤腿在姿势稳定中的贡献，导致健康腿在姿势稳定性过程中更大程度地参与。这些特征在受伤后 10 天内大大减少。
