Background: Dairy farming involves physically demanding activities, increasing WRMSD risk in low back, shoulders, and upper limbs. Limited data exists for Perambalur District farmers.

Methods: A cross-sectional survey of 200 dairy farmers used the Nordic Musculoskeletal Questionnaire (NMQ) to assess 12-month WRMSD prevalence. Data analyzed via descriptive statistics and chi-square tests (p<0.05).

Results: Overall WRMSD prevalence was 82%, highest in low back (58%), shoulders (45%), and knees (32%). Risk factors included milking (OR=2.8), heavy loads (OR=3.1), and >10 years experience (p=0.02). Females reported higher upper limb issues (52% vs. 38%).

Conclusion: High WRMSD burden demands ergonomic interventions and awareness programs for Perambalur dairy farmers.
