摘要
目的探讨单侧功能性踝关节不稳(functional ankle instability,FAI)人群在连续纵跳(continuous vertical jump,CVJ)落地过程中的下肢生物力学特征以及下肢偏侧性,并与健康人群进行对比。方法选取14名单侧FAI男性作为实验组,匹配14名无踝关节损伤男性为对照组,两组均执行30次CVJ落地任务。运用Vicon和Kistler设备分别对两组受试者在第1、15、30次CVJ落地过程中的下肢运动学、动力学特征进行同步采集,对数据采用2×3混合方差分析。结果FAI患者在执行CVJ落地任务时,患侧肢体与健康人群的运动学、动力学特征无明显差异,但在vGRF峰值SI上表现出更高的偏侧性。尽管随着跳落任务次数的增加和疲劳程度的上升,人体会调整下肢动作模式,但这种调整似乎并未对FAI患者患侧下肢的生物力学特征和下肢偏侧性产生明显影响。结论研究结果为预防FAI人群踝关节反复扭伤或者伤后重返赛场前的康复训练提供理论依据。在FAI患者的康复训练中应重视纠正下肢偏侧性,以减少潜在的长期损伤风险,并考虑生物力学适应性以实现全面康复。
Objective This study investigated lower limb biomechanics and lateral asymmetry during the continuous vertical jump(CVJ)landing process in individuals with unilateral functional ankle instability(FAI)and compared these characteristics with those of healthy individuals.Methods Fourteen males with unilateral FAI were selected as the experimental group,and 14 males without ankle joint injury were matched to the control group.Both the groups performed 30 CVJ landing tasks.Lower limb kinematic and kinetic characteristics during the 1st,15th,and 30th CVJ landings were synchronously collected using Vicon and Kistler equipment,and a 2×3 mixed analysis of variance was adopted for the data.Results In the execution of CVJ landing tasks,patientswith FAI demonstrated no significant differences in the kinematic and kinetic characteristics of the affected limbscompared with healthy controls.However,a greater degree of lateral asymmetry was observed in the FAI group,particularly in the symmetry index(SI)of the vGRF peak.Despite the increase in the number of jump landingsand consequent increase in fatigue levels,which led to adjustments in lower limb movement patterns,theseadjustments did not appear to have a significant impact on the biomechanical characteristics and asymmetry of theaffected limb in patients with FAI.Conclusions This study provides a theoretical basis for the prevention ofrecurrent ankle sprains in patients with FAI,as well as rehabilitation training prior to their return to sports.Thesefindings underscore the importance of addressing lower limb asymmetry in the rehabilitation training of patientswith FAI to reduce the risk of potential long-term injuries.When formulating rehabilitation plans for patients withFAI,particular attention should be paid to the correction of lower limb asymmetry with consideration ofbiomechanical adaptability under different states to achieve a more comprehensive rehabilitation outcome.
