摘要

本研究的目的是研究矢状面屈伸过程中躯干和骨盆运动学以及节段间协调的规范性和年龄相关性差异。当76名参与者在矢状面上进行最大运动范围的任务时,记录了躯干和骨盆的运动学。计算互相关以确定相邻分段运动之间的相位滞后,并使用矢量编码计算耦合角,并将其分类为4种协调模式之一:同相、反相、上相位和下相位。使用双向混合模型多变量方差分析来比较各组之间的腰椎和骨盆角度运动学、相位滞后和互相关系数。与中年参与者相比,年轻参与者的躯干活动范围更大。在两个年龄组的屈曲和伸展运动中,腰椎和骨盆主要以最小的相位滞后旋转,在过度伸展和恢复直立姿势时,两组之间的协调性存在差异。总之,中年人表现出较低的运动范围,但保持着与年轻人相似的运动模式,这可归因于保护机制。健康的腰椎和骨盆运动模式很重要,需要将其量化为基线,用于制定脊柱疾病患者的康复方案。

Effect of Age on Thoracic, Lumbar, and Pelvis Coordination During Trunk Flexion and Extension.
The purpose of this study was to investigate normative and age-related differences in trunk and pelvis kinematics and intersegmental coordination during sagittal plane flexion-extension. Trunk and pelvis kinematics were recorded while 76 participants performed a maximal range of motion task in the sagittal plane. Cross-correlation was calculated to determine the phase lag between adjacent segment motion, and coupling angles were calculated using vector coding and classified into one of 4 coordination patterns: in-phase, antiphase, superior, and inferior phase. A 2-way mixed-model multivariate analysis of variance was used to compare lumbar spine and pelvis angular kinematics, phase lags, and cross-correlation coefficients between groups. Young participants exhibited greater trunk range of motion compared with middle-aged participants. The lumbar spine and pelvis were predominantly rotating with minimum phase lag during flexion and extension movement for both age groups, and differences in coordination between the groups were seen during hyperextension and return to upright position. In conclusion, middle-aged adults displayed lower range of motion but maintained similar movement patterns to young adults, which could be attributed to protective mechanisms. Healthy lumbar and pelvis movement patterns are important to understand and need to be quantified as a baseline, which can be used to develop rehabilitation protocols for individuals with spinal ailments.

期刊介绍: The mission of the Journal of Applied Biomechanics (JAB) is to disseminate the highest quality peer-reviewed studies that utilize biomechanical strategies to advance the study of human movement. Areas of interest include clinical biomechanics, gait and posture mechanics, musculoskeletal and neuromuscular biomechanics, sport mechanics, and biomechanical modeling. Studies of sport performance that explicitly generalize to broader activities, contribute substantially to fundamental understanding of human motion, or are in a sport that enjoys wide participation, are welcome. Also within the scope of JAB are studies using biomechanical strategies to investigate the structure, control, function, and state (health and disease) of animals.
