Shoulder injuries: Common problems for truck drivers
Throughout Georgia, many hard-working truck drivers are reaching their intended destinations. With that said, these people do much more than drive. One part of being a truck driver is raising and lowering trailers. To do this, they must crank landing gears. While this might sound like a simple task, a new study found that it’s a frequent contributor to shoulder injuries among truck drivers.
A new study links truck drivers and shoulder injuries
In 2019, North Carolina State University and the Washington State Department of Labor & Industries wanted to research a group of 12 truck drivers. The purpose of this research was to study their shoulder muscle activity and range of motion while cranking landing gears.
This study looked at frontal cranking, which occurs when drivers perpendicularly crank gear handles and face their trailer. They also looked at sagittal cranking, which involves a driver standing parallel to the crank they’re using.
Sagittal cranking vs frontal cranking: which is worse?
Sagittal cranking uses the driver’s whole body. Frontal cranking primarily uses the shoulder muscles. In the previously mentioned study, the researchers found that frontal cranking leads to far more injured shoulders than sagittal cranking.
Frontal cranking causes more injuries because this method requires more use of the shoulder muscles than sagittal cranking. This study also found that frontal cranking caused significantly more grinding of the shoulder’s ligaments. Frontal cranking also wore down the driver’s shoulders faster than sagittal cranking. Over time, it’s possible for lots of long-term cranking to lead to workplace injuries.
As you can see, truck drivers are often at risk for shoulder injuries. These injuries often occur whenever drivers are lowering or raising their truck’s trailer, and they can qualify for workers’ compensation.
