评估腕外骨骼适配的工效，降低鞍具厂工人上肢损伤风险
Ergonomic Assessment of Work Activities for an Industrial-oriented Wrist Exoskeleton
- 通过问卷和表面肌电测量评估5名工人作业时的肌肉负荷
- 发现上肢劳损率超40%，尤其集中在手腕与手臂部位
- 为无法自动化的手工工序设计可穿戴外骨骼提供依据
肌肉骨骼疾病（MSD）是全球约17亿人工作中受伤和生产损失的主要原因，主要影响腰背（超过50%）和上肢（超过40%）。本文针对一家马鞍制造企业中的不同工作活动进行工效学评估，涉及5名工人。该研究旨在指导腕部外骨骼的设计，以在无法实现自动化生产流程的情况下降低肌肉骨骼疾病风险。评估采用主观（问卷）和客观（表面肌电，sEMG）两种方式，分别测量工人感知负担与实际肌肉激活水平。
原文摘要 · Abstract (English)
Musculoskeletal disorders (MSD) are the most common cause of work-related injuries and lost production involving approximately 1.7 billion people worldwide and mainly affect low back (more than 50%) and upper limbs (more than 40%). It has a profound effect on both the workers affected and the company. This paper provides an ergonomic assessment of different work activities in a horse saddle-making company, involving 5 workers. This aim guides the design of a wrist exoskeleton to reduce the risk of musculoskeletal diseases wherever it is impossible to automate the production process. This evaluation is done either through subjective and objective measurement, respectively using questionnaires and by measurement of muscle activation with sEMG sensors.
