Abstract

Background: Work-related musculoskeletal disorders are a significant cause of ill health among working populations. Vehicle repair mechanics are at high risk due to their work nature.

Objectives: To investigate the prevalence, pattern, and severity of musculoskeletal disorders among automotive repair mechanics in Mumbai, India, and to analyze associated postural risks.

Methodology: A cross-sectional study was conducted on 423 garage mechanics in Mumbai. Data were collected using a self-administered questionnaire. Postural risks were analyzed using the Rapid Entire Body Assessment (REBA) scale. Joint angles were measured using Kinovea software. Descriptive statistics and correlation analyses were performed.

Results: Among 423 mechanics, 23 (5.4%) reported pain, primarily in the lower back (26.1%) and knees (34.8%). The median age was 29 years (IQR: 9). Most mechanics worked 10-12 h daily (51.1%), 7 days a week (70.4%). REBA scores were significantly correlated with trunk posture (r = 0.645, P = 0.001) and Score A (r = 0.85, P < 0.001). Lower back pain showed a positive correlation with REBA scores (r = 0.050, P = 0.819).

Conclusions: The prevalence of musculoskeletal pain among vehicle repair mechanics in this sample was relatively low. However, those who reported pain primarily experienced lower back and knee pain. Postural risks, particularly trunk posture, were significantly associated with overall ergonomic risk.

在引擎盖下-解码孟买市区车辆机械师的肌肉骨骼健康：一项横断面研究。

背景：与工作相关的肌肉骨骼疾病是导致工作人群健康状况不佳的重要原因。汽车维修技工的工作性质决定了他们的工作风险很高。目的：调查印度孟买汽车维修技工中肌肉骨骼疾病的患病率、模式和严重程度，并分析相关的姿势风险。方法：对孟买423名车库技工进行了横断面研究。数据是通过自我管理的问卷收集的。采用快速全身评估（REBA）量表分析体位风险。关节角测量采用Kinovea软件。进行描述性统计和相关分析。结果：在423名机械师中，23名（5.4%）报告疼痛，主要在下背部（26.1%）和膝盖（34.8%）。中位年龄为29岁（IQR: 9）。大多数机械师每天工作10-12小时（51.1%），每周工作7天（70.4%）。REBA评分与躯干姿势（r = 0.645, P = 0.001）和A评分（r = 0.85, P < 0.001）显著相关。腰痛与REBA评分呈正相关（r = 0.050, P = 0.819）。结论：该样本中汽车维修技工的肌肉骨骼疼痛患病率相对较低。然而，那些报告疼痛的人主要是腰背部和膝盖疼痛。姿势风险，尤其是躯干姿势，与整体人体工程学风险显著相关。
