Prevalence of Work-Related Upper Extremity Symptoms and Functional Impairment in Heavy Vehicle Drivers

Abstract

Background: Heavy vehicle drivers are exposed to occupational hazards like prolonged static postures, poor ergonomics,

repetitive upper limb uses. These factors contribute to a high prevalence of upper extremity musculoskeletal disorders. Such

conditions can cause pain, dysfunction, and decreased work efficiency, especially with increasing age and prolonged driving

hours, significantly impacting upper limb function and daily activities.

Objective: This study aimed to determine the prevalence of work-related upper extremity symptoms and assess their impact on

functional impairment among heavy vehicle drivers using the DASH (Disabilities of the Arm, Shoulder, and Hand) questionnaire.

Methodology: A cross-sectional study was conducted among 51 heavy vehicle drivers aged 28–54 years in Greater Noida.

Inclusion criteria included age (25–55 years), driving experience (5–15 years), and daily driving duration (6–7 hours). Drivers

with recent injuries, surgeries, or irregular work schedules were excluded. Statistical analysis explore the relationship between

age and upper extremity function.

Result: The mean age of participants was 39.37±7.77 years, and the mean DASH score was 17.63±7.55, indicating mild to

moderate upper extremity disability. A strong, statistically significant positive correlation (r = 0.8675, p < 0.0001) was found

between age and DASH scores, suggesting that older drivers reported more significant upper extremity functional impairment.

Conclusion: The study revealed a high prevalence of upper extremity musculoskeletal symptoms among heavy vehicle drivers,

with age being a significant factor in increasing functional impairment. Regular screening, ergonomic interventions, preventive

strategies and promoting occupational health.
