Summary
Professional drivers experience high rates of spinal disorders, particularly neck and back pain. This study found that specific driving postures significantly increase neck and trunk loading, correlating with reported discomfort.
Area of Science:
- Occupational Health
- Ergonomics
- Biomechanics
Background:
- Professional drivers frequently suffer from spinal disorders, leading to significant morbidity and early retirement.
- Work-related upper-limb disorders are common in this population due to prolonged and often awkward postures.
Purpose of the Study:
- To evaluate the exposure to risk factors associated with work-related upper-limb disorders in professional drivers using the RULA method.
- To investigate the association between specific driving postures and self-reported trunk and neck pain.
Main Methods:
- The study utilized the Rapid Upper Limb Assessment (RULA) method to assess the working postures of 77 professional drivers.
- Drivers of rubbish-collection and road-washing vehicles were analyzed, comparing standard postures with those involving neck and trunk flexion, bending, and twisting.
Main Results:
- A significant association was found between trunk and neck RULA scores and self-reported pain in these regions for all drivers.
- High neck loading was evident in both driving postures studied.
- Posture scores differed significantly between drivers using adjustable versus non-adjustable seats.
Conclusions:
- The RULA method is a suitable tool for rapidly evaluating neck and trunk loading in professional truck drivers.
- Findings highlight the ergonomic risks associated with specific driver postures and seat adjustability, contributing to spinal disorders.
