下背痛（LBP）的特点是活动受限，特别是涉及弯曲的任务。背部运动服技术减少了下背部不适，提高了LBP患者在弯曲和提升任务中的自我效能。然而，这些器械在LBP患者中的生物力学有效性尚不清楚。本研究旨在确定旨在帮助LBP矢状面弯曲个体的软主动背部外装护具的生物力学和感知效果。了解患者报告的该器械的可用性和用例。15名患有LBP的人在有和没有外装服的情况下进行了两次实验性提升。躯干生物力学测量肌肉激活幅度，和全身运动学和动力学。为了评估设备感知，参与者对任务努力、腰部不适和完成日常活动的关注程度进行了评级。背部运动服减少了背伸肌的峰值：提升时，力矩减少了9%，肌肉振幅减少了16%。与不使用机器护甲的提升相比，腹部共同激活和最大躯干屈曲的小幅减少没有变化。参与者报告说，与没有外装服相比，使用外装服的任务努力、背部不适以及对弯曲和提升的担忧较低。这项研究表明，背部运动服不仅赋予减少任务努力，不适和增加LBP个体的信心的感知益处，而且它通过可测量的生物力学减少背部伸肌努力来实现这些益处。这些好处的综合效果意味着背部外装可能是一种潜在的治疗辅助手段，可以增强物理治疗、锻炼或日常活动。
Low back pain (LBP) is hallmarked by activity limitations, especially for tasks involving bending. Back exosuit technology reduces low back discomfort and improves self-efficacy of individuals with LBP during bending and lifting tasks. However, the biomechanical efficacy of these devices in individuals with LBP is unknown. This study sought to determine biomechanical and perceptual effects of a soft active back exosuit designed to assist individuals with LBP sagittal plane bending. To understand patient-reported usability and use cases for this device. Fifteen individuals with LBP performed two experimental lifting blocks once with and without an exosuit. Trunk biomechanics were measured by muscle activation amplitudes, and whole-body kinematics and kinetics. To evaluate device perception, participants rated task effort, low back discomfort, and their level of concern completing daily activities. The back exosuit reduced peak back extensor: moments by 9%, and muscle amplitudes by 16% when lifting. There were no changes in abdominal co-activation and small reductions maximum trunk flexion compared to lifting without an exosuit. Participants reported lower task effort, back discomfort, and concern about bending and lifting with an exosuit compared to without. This study demonstrates a back exosuit not only imparts perceptual benefits of reduced task effort, discomfort, and increased confidence in individuals with LBP but that it achieves these benefits through measurable biomechanical reductions in back extensor effort. The combined effect of these benefits implies back exosuits might be a potential therapeutic aid to augment physical therapy, exercises, or daily activities.
