Lower back pain, a common issue among pregnant women, often complicates daily activities like standing up from a chair. Therefore, research into the standing motion of pregnant women is important, and many research studies have already been conducted. However, many of these studies were conducted in highly controlled environments, overlooking everyday scenarios such as using a desk for support when standing up, and their effects have not been adequately tested. To address this gap, we measured multimodal signals for a sit-to-stand (STS) movement with hand assistance and verified the changes using a -test. To avoid imposing strain on pregnant women, we used 10 non-diseased young adults who wore jackets designed to simulate pregnancy conditions, thus allowing for more comprehensive and rigorous experimentation. We attached surface electromyography (sEMG) sensors to the erector spinae muscles of participants and measured changes in muscle activity, skeletal positioning, and center of pressure both before and after wearing a Maternity-Simulation Jacket. Our analysis showed that the jacket successfully mimicked key aspects of the movement patterns typical in pregnant women. These results highlight the possibility of developing practical strategies that more accurately mirror the real-life scenarios met by pregnant women, enriching the current research on their STS movement.
下背部疼痛是孕妇常见的问题，常常使诸如从椅子上站起来等日常活动变得复杂。因此，对孕妇站立动作的研究很重要，并且已经进行了许多研究。然而，这些研究大多是在高度受控的环境中进行的，忽略了诸如站立时借助桌子支撑等日常场景，其效果尚未得到充分测试。为了填补这一空白，我们测量了借助手部辅助从坐姿到站姿（STS）动作的多模态信号，并使用t检验验证了变化情况。为避免给孕妇造成压力，我们使用了10名未患病的年轻成年人，他们穿着旨在模拟怀孕状况的夹克，从而能够进行更全面、更严谨的实验。我们将表面肌电图（sEMG）传感器附着在参与者的竖脊肌上，测量穿着孕妇模拟夹克前后肌肉活动、骨骼位置和压力中心的变化。我们的分析表明，该夹克成功模拟了孕妇典型运动模式的关键方面。这些结果凸显了制定更准确反映孕妇实际生活场景的实用策略的可能性，丰富了当前对其STS动作的研究。
