Upper trapezius myalgia represents a prevalent musculoskeletal disorder characterized by chronic cervicobrachial pain, frequently exacerbated by psychosocial stress, sustained postural loading, and occupational demands. In peri-urban communities such as Sarfabad, these physical stressors contribute significantly to functional disability and diminished psychological well-being. This community-based, quasi-experimental study aimed to implement and evaluate a low-cost, multi-modal physiotherapy intervention designed to mitigate pain and enhance functional capacity. Fifteen adults (n=15) presenting with upper trapezius pain (≥2/10 NPRS) were recruited for a one-week structured program comprising targeted education, Deep Cervical Flexor (DCF) training, scapular strengthening, and ergonomic modifications.

Results indicated a statistically significant reduction in mean pain intensity from 5.8 to 2.1 (-64%) and a marked decrease in severe functional disability cases from 53% to 13%. Furthermore, the intervention improved adherence to micro-breaks by 60%, suggesting positive behavioral adoption.
