This study investigated age-related differences in trunk kinematics during walking in healthy men. Secondary aims were to investigate the covarying effects of physical activity (PA) and lumbar paravertebral muscle (LPM) morphology on trunk kinematics, and the effect of age on interplanar coupling between the trunk and pelvis. Three-dimensional (3D) trunk and pelvis motion data were obtained for 12 older (67.3 ± 6.0 years) and 12 younger (24.7 ± 3.1 years) healthy men during walking at a self-selected speed along a 10 m walkway. Phase-specific differences were observed in the coronal and transverse planes, with midstance and swing phases highlighted as instances when trunk and pelvic kinematics differed significantly ( < 0.05) between the younger group and older group. Controlling for age, fewer significant positive correlations were revealed between trunk and pelvic ranges and planes of motion. LPM morphology and PA were not significant covariates of age-related differences in trunk kinematics. Age-related differences in trunk kinematics were most apparent in the coronal and transverse planes. The results further indicate ageing causes an uncoupling of interplanar upper body movements during gait. These findings provide important information for rehabilitation programmes in older adults designed to improve trunk motion, as well as enable identification of higher-risk movement patterns related to falling.
本研究调查了健康男性行走过程中躯干运动学的年龄相关差异。次要目的是研究身体活动（PA）和腰段椎旁肌（LPM）形态对躯干运动学的协变影响，以及年龄对躯干与骨盆间平面耦合的影响。在12名老年（67.3±6.0岁）和12名年轻（24.7±3.1岁）健康男性以自定速度沿10米步道行走期间，获取了三维（3D）躯干和骨盆运动数据。在冠状面和横断面观察到了特定阶段差异，其中支撑中期和摆动期被突出显示为年轻组和老年组之间躯干和骨盆运动学存在显著差异（<0.05）的情况。在控制年龄后，躯干和骨盆运动范围及平面之间的显著正相关较少。LPM形态和PA不是躯干运动学年龄相关差异的显著协变量。躯干运动学的年龄相关差异在冠状面和横断面最为明显。结果进一步表明，衰老会导致步态期间上半身平面间运动的解耦。这些发现为旨在改善躯干运动的老年人康复计划提供了重要信息，同时也有助于识别与跌倒相关的高风险运动模式。
