Concern details
Truck drivers spend extended periods of time sitting in their trucks. Occupational drivers have also been shown to increase risk for developing musculoskeletal disorders, particularly, for low back pain (LBP). Truck drivers are exposure to the following concerns:
- Prolonged static postures while driving.
- Some trucks have poor adjustability of seats, steering wheels and pedals which do not accommodate all potential drivers and results in awkward postures for others.
- Exposure to whole body vibration.
- Cab design where gauges maybe difficult to see and controls which are hard to reach.
- Seats do not always line up with steering wheel.
- Repetitive gear shifting with manual transmissions.
