Musculoskeletal disorders are the most common among farmers and farming constitutes the highest industrial accident rate. To prevent these, we developed a smart auxiliary workwear and investigated its effectiveness through human impact assessment experiments. In our method, the actuator of the waist elastic band was released when there was no need to directly adjust the length with the strength support of the waist, and the elastic band was held once the motion using the waist strength disappeared. To examine the performance, 15 workers were recruited; before the experiment, they were subjected to a basic fitness evaluation to examine their general characteristics. The lumbar peak torques before and after wearing the designed work clothes were measured using the Biodex System III to determine their lumbar assistance power, which was confirmed to have increased by approximately 17%. In addition, electromyographic comparison of the amount of muscle used before and after the wearing revealed that the muscle use was reduced by 26.41% and 19.38% after wearing the work clothes when the weight was lifted in the stooping and squatting postures, respectively. Based on these results, it can be stated that the proposed smart assistive work clothes could contribute to reduced muscle usage required for work and lessen related weariness by supporting the waist, and thus, would greatly help farmers in preventing musculoskeletal disorders.

重复性农业任务穿戴式辅助服的生理信号分析

肌肉骨骼疾病是农民中最常见的疾病，农业是最高的工业事故率。为了防止这些，我们开发了一种智能辅助工作服，并通过人体影响评估实验研究了它的有效性。在我们的方法中，腰部松紧带的致动器在不需要直接调节长度时，通过腰部的力量支撑释放，一旦使用腰部力量的运动消失，松紧带被握住。为了检查绩效，招募了 15 名工人；在实验之前，他们接受了基本的健康评估，以检查他们的一般特征。使用Biodex System III测量穿着设计工作服前后的腰椎峰值扭矩，以确定其腰椎辅助力量，经证实增加了约 17%。此外，对穿着前后肌肉使用量的肌电图比较显示，在弯腰和蹲姿举重时，穿着工作服后肌肉使用量分别减少了26.41%和19.38%。基于这些结果，可以说，所提出的智能辅助工作服有助于减少工作所需的肌肉使用，并通过支撑腰部减少相关的疲劳，因此将极大地帮助农民预防肌肉骨骼疾病。38%的人在穿着工作服后，分别以弯腰和蹲姿举重。基于这些结果，可以说，所提出的智能辅助工作服有助于减少工作所需的肌肉使用，并通过支撑腰部减少相关的疲劳，因此将极大地帮助农民预防肌肉骨骼疾病。38%的人在穿着工作服后，分别以弯腰和蹲姿举重。基于这些结果，可以说，所提出的智能辅助工作服有助于减少工作所需的肌肉使用，并通过支撑腰部减少相关的疲劳，因此将极大地帮助农民预防肌肉骨骼疾病。
