This study aimed to investigate the effects of wearing extensible and non-extensible lumbar belt (LB) on biomechanical factors of the sit-to-stand (STD) movement and pain-related psychological factors affecting office workers with low back pain. Among 30 office workers, 15 with low back pain (LBP) were assigned to the experimental group and 15 healthy adults were assigned to the control group. The participants performed STD movement in random order of three different conditions: without LB (Condition 1), with extensible LB (Condition 2), and with non-extensible LB (Condition 3). Biomechanical variables of STD movement in each condition were measured using a three-dimensional motion analysis system and force plate. Pain-related psychological factors were measured only in the experimental group. Among the biomechanical factors of STD movement, an interaction effect was found in the maximum anterior pelvic tilt angle and total-phase range of motion of the trunk ( < 0.05). Pain intensity, pain-related anxiety, and pain catastrophizing were decreased in the conditions with lumbar belts (Conditions 2 and 3) compared to the condition without LB (Condition 1) ( < 0.05). Extensible and non-extensible lumbar belts engender biomechanically beneficial effects during STD movement in both office workers with LBP and healthy office workers. Further, pain intensity, pain-related anxiety, and pain catastrophizing were decreased in office workers with LBP. Therefore, both types of extensible lumbar belts may be helpful in the daily life of patients with LBP and office workers.
本研究旨在探讨佩戴可伸展和不可伸展的腰带（LB）对从坐到站（STD）动作的生物力学因素以及影响患有下背痛的上班族的疼痛相关心理因素的影响。在30名上班族中，15名患有下背痛（LBP）的被分配到实验组，15名健康成年人被分配到对照组。参与者按照三种不同条件的随机顺序进行STD动作：不佩戴腰带（条件1）、佩戴可伸展腰带（条件2）和佩戴不可伸展腰带（条件3）。使用三维运动分析系统和测力板测量每种条件下STD动作的生物力学变量。仅在实验组中测量疼痛相关的心理因素。在STD动作的生物力学因素中，在前倾骨盆最大角度和躯干全阶段运动范围方面发现了交互作用（<0.05）。与不佩戴腰带的条件（条件1）相比，佩戴腰带的条件（条件2和3）下疼痛强度、疼痛相关焦虑和疼痛灾难化程度降低（<0.05）。可伸展和不可伸展的腰带在患有LBP的上班族和健康上班族的STD动作过程中都产生了生物力学上的有益效果。此外，患有LBP的上班族的疼痛强度、疼痛相关焦虑和疼痛灾难化程度降低。因此，这两种类型的可伸展腰带可能对患有LBP的患者和上班族的日常生活有所帮助。
