Pelvic and hip motion are pivotal in maintaining postural control and energy efficient gait. An insight into influence of age and gender on the coupled motion of hip and pelvis in gait-cycle will guide clinical rehabilitation strategies and pertinent technology-design for specific age-groups. Therefore, present study evaluated pelvic and hip-joint gait kinematics in healthy females and males across adult-hood.
Following signed-informed consent, pelvic and hip kinematics in 3-planes during stance-phase of gait were measured using 12-camera motion system and 2 force-plates, in 200 healthy Indian female and male volunteers (19-60years) stratified into 4-groups (19-30 years; 31-40 years; 41-50years; 51-60 years).
With advancing age, males and females demonstrated a gradual rise in hip adduction (p < 0.01) in coronal plane. Sagittal plane pelvic and hip kinematics did not change with advancing age among males whereas females above 30 years Demonstrated greater pelvic drop (49%), pelvic tilt (35%) and hip adduction (69%) compared to females below 30 years (p < 0.01). In comparison to males, females demonstrated greater peak anterior pelvic tilt (32%), greater pelvic hike (28%) and protraction (28%) in 50-60 years age-group (p < 0.05). Females across all age-groups demonstrated greater hip adduction compared to males (p < 0.05).
Present findings add age and gender characterized gait-kinematics data of healthy adults from the most populous country to the existing 3-D data of gait from different populations. Clinicians and engineers, can leverage this knowledge of changing gait kinematics of healthy adults to design specific therapeutic strategies for aging men and women to optimize gait kinematics and advance design and development of locomotor technology suitable for people with rehabilitation needs across the globe.
骨盆和髋关节的运动对于维持姿势控制和高效节能的步态至关重要。深入了解年龄和性别对步态周期中髋关节和骨盆联合运动的影响，将为特定年龄组的临床康复策略和相关技术设计提供指导。因此，本研究评估了成年期健康女性和男性的骨盆和髋关节步态运动学。
在获得签署的知情同意书后，使用12台摄像机运动系统和2块测力板，对200名健康的印度女性和男性志愿者（19 - 60岁）在步态站立期的三个平面内的骨盆和髋关节运动学进行了测量，这些志愿者被分为4组（19 - 30岁；31 - 40岁；41 - 50岁；51 - 60岁）。
随着年龄的增长，男性和女性在冠状面的髋关节内收角度均逐渐增加（p < 0.01）。在矢状面，男性的骨盆和髋关节运动学并未随年龄增长而改变，而30岁以上的女性与30岁以下的女性相比，骨盆下降幅度更大（49%）、骨盆倾斜度更大（35%）以及髋关节内收角度更大（69%）（p < 0.01）。在50 - 60岁年龄组中，与男性相比，女性的骨盆前倾峰值更大（32%）、骨盆抬高幅度更大（28%）以及骨盆前伸幅度更大（28%）（p < 0.05）。所有年龄组的女性髋关节内收角度均大于男性（p < 0.05）。
本研究结果为来自人口最多国家的健康成年人增添了具有年龄和性别特征的步态运动学数据，补充到现有的不同人群的三维步态数据中。临床医生和工程师可以利用这些关于健康成年人步态运动学变化的知识，为老年男性和女性设计特定的治疗策略，以优化步态运动学，并推动适合全球有康复需求人群的运动技术的设计与开发。
