[Purpose] This study compared the coordination patterns of the trunk and pelvis in the transverse plane between healthy subjects and patients with chronic low back pain during an anterior load carriage task at various walking speeds. [Subjects] Ten healthy subjects and 10 patients with chronic low back pain performed an anterior carriage task with a load of 10% body weight at walking speeds of 3.5, 4.5, or 5.5 km/h. [Methods] The trunk and pelvic kinematics were measured by using a motion analysis system. During the anterior carriage task, the continuous relative phase differed significantly between groups with respect to walking speed. [Results] The continuous relative phase was more anti-phase in the chronic low back pain group than the control group. The inter-group continuous relative phase pattern was affected by walking at 5.5 km/h. [Conclusion] Compared to controls, subjects with chronic low back pain are unable to establish an in-phase between the trunk and pelvis from walking at 3.5 to 5.5 km/h during an anterior carriage task.
[目的] 本研究比较了健康受试者和慢性下腰痛患者在不同步行速度下进行前向负载搬运任务时，躯干和骨盆在横断面的协调模式。[受试者] 10名健康受试者和10名慢性下腰痛患者以3.5、4.5或5.5 km/h的步行速度进行了一项负载为体重10%的前向搬运任务。[方法] 使用运动分析系统测量躯干和骨盆的运动学。在前向搬运任务期间，两组之间的连续相对相位在步行速度方面存在显著差异。[结果] 慢性下腰痛组的连续相对相位比对照组更呈反相位。组间连续相对相位模式受5.5 km/h步行速度的影响。[结论] 与对照组相比，慢性下腰痛受试者在进行前向搬运任务时，无法在3.5至5.5 km/h的步行速度下在躯干和骨盆之间建立同相位。
