This study was aimed to establish the reference values of ankle kinematics and factors associated with ankle kinematics of healthy Thai adults.
A prospective cohort was conducted among healthy volunteers aged between 18 and 40 years and evaluated gait analysis between 2016 and 2020. After applying the modified Halen Hayes marker set, participants were assigned to walk 8-10 rounds with their preferred speed. Demographic data i.e., age, gender and body mass index (BMI) and ankle kinematics (varus-valgus, dorsiflexion-plantar flexion, foot progression, and ankle rotation) using motion analysis software were recorded and analyzed.
98 volunteers (60 females and 38 males) aged 28.6 ± 5.4 years with body mass index 21.2 ± 2.0 kg/m were included. The average ranges of ankle kinematics entire gait cycle were varus-valgus -1.62 to 3.17 degrees, dorsiflexion-plantar flexion 0.67 to 14.52 degrees, foot progression -21.73 to -8.47 degrees, and ankle rotation 5.22 to 9.74 degrees. The ankle kinematic data in this study population was significantly different from the normal values supplied by OrthoTrak software of the motion analysis program, especially more ankle internal rotation at mid-stance (5.22 vs. -12.10 degrees) and terminal stance (5.48 vs. -10.74 degrees) with < 0.001. Foot progression significantly exhibited more external rotation for 1.5 degrees on the right compared to the left side, and for 5 degrees more in males than females. One increment in age was significantly correlated with ankle internal rotation at mid-swing (coefficient 0.21 degrees, = 0.039). BMI had no statistical association with ankle kinematics. Statistical parametric mapping for full-time series of angle assessments showed significantly different foot progression at initial contact and terminal stance between sides, and our ankle kinematics significantly differed from the reference values of the motion analysis program in all planes ( < 0.05).
The reference of ankle kinematics of Thai adults was established and differences between sides and the normal values of the motion analysis program were identified. Advanced age was associated with ankle internal rotation, and male gender was related to external foot progression. Further studies are needed to define all-age group reference values.
本研究旨在建立健康泰国成年人踝关节运动学的参考值以及与踝关节运动学相关的因素。
对18至40岁的健康志愿者进行前瞻性队列研究，并在2016年至2020年期间评估步态分析。应用改良的哈伦·海斯标记集后，让参与者以他们喜欢的速度行走8至10圈。记录并分析人口统计学数据，即年龄、性别和体重指数（BMI），以及使用运动分析软件得出的踝关节运动学数据（内翻-外翻、背屈-跖屈、足前进角和踝关节旋转）。
纳入了98名志愿者（60名女性和38名男性），年龄为28.6±5.4岁，体重指数为21.2±2.0kg/m²。整个步态周期中踝关节运动学的平均范围为：内翻-外翻-1.62至3.17度，背屈-跖屈0.67至14.52度，足前进角-21.73至-8.47度，踝关节旋转5.22至9.74度。本研究人群的踝关节运动学数据与运动分析程序的OrthoTrak软件提供的正常值有显著差异，尤其是在站立中期（5.22对-12.10度）和站立末期（5.48对-10.74度）踝关节内旋更多，P<0.001。足前进角在右侧比左侧明显多外旋1.5度，男性比女性多5度。年龄每增加一岁与摆动中期踝关节内旋显著相关（系数0.21度，P=0.039）。BMI与踝关节运动学无统计学关联。全时角度评估系列的统计参数映射显示，两侧在初始接触和站立末期的足前进角有显著差异，并且我们的踝关节运动学在所有平面上与运动分析程序的参考值有显著差异（P<0.05）。
建立了泰国成年人踝关节运动学的参考值，并确定了两侧之间以及与运动分析程序正常值的差异。高龄与踝关节内旋有关，男性与足外旋有关。需要进一步研究来确定所有年龄组的参考值。
