Praewa silk weavers are subject to numerous occupational risk factors that contribute to musculoskeletal disorders (MSDs), primarily due to inadequate occupational safety measures, limited access to health services, and substandard working conditions. The aim of this study was to assess the prevalence rate and determinants of MSDs among Praewa silk weavers. A cross-sectional study employing a convenience sampling method was conducted, involving 198 Praewa silk weavers from four provinces in the Northeast region of Thailand. Data collection was facilitated through a two-part research tool. The first part included a questionnaire assessment using demographic information, workplace conditions, and self-reported MSDs. The second part involved an ergonomic risk assessment using rapid upper limb assessment (RULA) and hand activity level (HAL). Descriptive statistics and multiple logistic regression analyses were conducted to determine the prevalence and associated factors of MSDs among participants. The findings revealed that the prevalence rates of MSDs in the past 7 days and 12 months were 68.68% and 96.46%, respectively. The highest prevalence rates of MSDs (over 60.00%) were observed in the wrists, fingers, and neck, with similar trends reported in both the past 7 days and 12 months. Key factors associated with MSDs over the past 12 months included low hand strength test results (adjusted odds ratio (AOR) = 2.09; 95%CI: 0.44-11.05), quite low hand strength test results (AOR=2.49; 95%CI: 0.29-21.15), weaving experience of 21-30 years (AOR=1.07; 95%CI: 0.20-5.64), age between 31-40 years (AOR=2.63; 95%CI: 0.49-13.91), age above 41 years (AOR=1.13; 95%CI: 1.08-1.19), RULA level 4 (AOR=3.62; 95%CI: 0.66-19.96), and HAL score exceeding 0.78 (AOR=0.63; 95%CI: 0.80-0.98) were significantly associated with MSDs during the past 12 months. This study highlights the high prevalence of MSDs among Praewa silk weavers, attributed to occupational risk factors such as low hand strength, high hand activity level, extensive weaving experience, and poor working posture. The weaving process itself is a significant contributor to these disorders. In conclusion, ergonomics interventions aimed at preventing MSDs, including postural training, injury prevention programs, and re-designed pull-cloth devices, are recommended to mitigate these risks.

普拉瓦丝绸编织工人面临多种职业风险因素，这些因素导致了肌肉骨骼疾病（MSDs）的高发率。主要原因在于缺乏适当的职业安全措施、有限的医疗服务获取途径以及较差的工作条件。本研究旨在评估泰国东北部四个省份198名普拉瓦丝绸编织工人的MSDs患病率及影响因素。采用方便抽样法进行横断面调查，数据收集使用了两部分的研究工具：第一部分包括问卷调查（人口统计信息、工作场所条件和自报告的MSDs），第二部分则是利用快速上肢评估（RULA）和手活动水平（HAL）来进行人因风险评估。通过描述性统计分析和多因素逻辑回归分析，研究确定了参与者中MSDs的发生率及相关的因素。结果显示，在过去7天内和12个月内MSDs的患病率分别为68.68%和96.46%。手、手指和颈部是最常见的疼痛部位，且在调查的两个时间段内均表现出类似的趋势。在过去一年中与MSDs显著相关的关键因素包括较低的手部力量测试结果（校正后的比值比(AOR) = 2.09；95%置信区间：0.44-11.05）、相当低的手部力量测试结果（AOR=2.49；95%CI: 0.29-21.15），拥有21至30年编织经验（AOR=1.07；95%置信区间：0.20-5.64），年龄在31至40岁之间（AOR=2.63；95%CI: 0.49-13.91），以及年龄超过41岁的工人（AOR=1.13；95%置信区间：1.08-1.19）、RULA等级为4级（AOR=3.62；95%CI: 0.66-19.96）和HAL评分超过0.78 (AOR=0.63; 95%CI: 0.80-0.98)。该研究强调了普拉瓦丝绸编织工人中MSDs的高发率，这些疾病主要与职业风险因素如较低的手部力量、较高的手活动水平、丰富的编织经验和不良的工作姿势相关。编织过程本身也是导致这些问题的重要原因之一。总之，建议采取包括姿态训练、伤害预防计划和重新设计拔布装置在内的人因干预措施来减轻这些风险。
