单腿着地（SLL）稳定性缺陷是外侧踝关节扭伤（LAS）后常见的功能障碍，与再损伤有关，需要解决。SLL稳定性缺陷可能与冲击吸收能力有关。因此，我们评估了这些关系。我们招募了46例慢性踝关节不稳定（CAI）患者和64例对照患者，测量了他们的运动学、SLL稳定性和冲击吸收能力。通过计算前后稳定指数（APSI）和中外侧稳定指数（MLSI）来评估SLL的稳定性。通过计算能量吸收（EA）来评价其冲击吸收能力。EA的负值大，说明吸收了大量的能量。日本版功能性踝关节不稳定性鉴定（IdFAI-J）评分（P < 0.001）、MLSI值（P = 0.004）、矢状面踝关节EA值（踝关节EA少）（P < 0.001）在CAI组显著高于对照组，矢状面膝关节EA值（膝关节EA多）（P < 0.041）在CAI组显著低于对照组。多元回归分析显示APSI与矢状面踝关节EA相关（β = 0.275, P = 0.004）。MLSI与矢状面踝关节EA （β = 0.204, P = 0.034）和idFAI评分（β = 0.234, P = 0.015）相关。LAS术后SLL稳定性损害与踝关节冲击吸收能力下降有关。
Single-leg landing (SLL) stability deficits are common dysfunctions after lateral ankle sprain (LAS), and are associated with reinjury and needs to be addressed. SLL stability deficits could be associated with impact absorption ability. Thus, we evaluated these relationships. We recruited 46 patients with chronic ankle instability (CAI) and 64 control patients and measured their kinematics, SLL stability, and impact absorption ability. The SLL stability was evaluated by calculating the anterior-posterior stability index (APSI) and medial–lateral stability index (MLSI). The impact absorption ability was evaluated by calculating the energy absorption (EA). The large negative value of the EA indicated the absorption of a large amount of energy. The Japanese version of identification of functional ankle instability (IdFAI-J) score (P < 0.001), MLSI value (P = 0.004), and sagittal plane ankle EA value (less EA at ankle joint) (P < 0.001) were significantly high in CAI, and sagittal plane knee EA value (more EA at knee joint) (P < 0.041) was significantly low in CAI than in the control group. Multiple regression analysis showed that the APSI was associated with sagittal plane ankle EA (β = 0.275, P = 0.004). The MLSI was associated with sagittal plane ankle EA (β = 0.204, P = 0.034) and the idFAI score (β = 0.234, P = 0.015). The SLL stability impairment after LAS was related to decreased impact absorption ability at the ankle joint.
