The aim of this study was to establish the presence of postural deficits in subjects with chronic ankle instability (CAI) and to assess the effect of an 8-week balance training program on dynamic postural control. A total of 43 subjects with CAI and 31 controls participated in this case-control study. Participants with CAI performed an 8-week home-based balance training, including 3 sessions a week. As main outcome measure, postural control was quantified after a vertical drop by means of the dynamic postural stability index (DPSI). Perceptual outcomes were documented using the FADI, FADI-Sport and VAS scales. At baseline, subjects with CAI displayed higher anterior/posterior and vertical postural instability, a poorer DPSI, and lower subjective stability scores compared to the control group. After balance training, all subjective stability scores improved significantly, although no changes were noted for the stability indices. In conclusion, subjects with CAI have an impaired postural control. As a treatment modality, balance training exhibits the capability of improving the subjective feeling of instability in subjects with CAI. However, there was no effect on dynamic postural control. Further research on the explanatory mechanisms of balance training is warranted, and other training modalities should be considered.
本研究的目的是确定慢性踝关节不稳（CAI）患者是否存在姿势缺陷，并评估为期8周的平衡训练计划对动态姿势控制的影响。共有43名CAI患者和31名对照者参与了这项病例对照研究。CAI患者进行了为期8周的家庭平衡训练，每周3次。作为主要结局指标，通过动态姿势稳定性指数（DPSI）对垂直下落后的姿势控制进行量化。使用FADI、FADI-Sport和VAS量表记录感知结果。在基线时，与对照组相比，CAI患者表现出更高的前后向和垂直姿势不稳、更差的DPSI以及更低的主观稳定性评分。平衡训练后，所有主观稳定性评分均显著改善，尽管稳定性指标未发现变化。总之，CAI患者存在姿势控制受损。作为一种治疗方式，平衡训练具有改善CAI患者主观不稳感的能力。然而，对动态姿势控制没有影响。有必要对平衡训练的解释机制进行进一步研究，并应考虑其他训练方式。
