Commercial Motor Vehicle drivers can be at a higher risk for developing Carpal Tunnel Syndrome. Carpal Tunnel Syndrome occurs from prolonged gripping of the steering wheel which can compress the median nerve in the wrist.
The median nerve runs from the neck down to the arm and hand. Because the carpal tunnel is a narrow passageway, the ligaments and bones which the nerve passes through can become inflamed, swollen, and irritated, potentially causing symptoms such as pain, tingling, and numbness.
Symptoms may include:
- Tingling or numbness in the fingers
- Difficulty making a fist or gripping small objects
- Hand weakness
- Hand or finger pain
- A burning sensation that moves up to the elbow or neck
One of the main causes of Carpal Tunnel Syndrome is caused by extreme flexion or extension of the hand and wrist. Changing how you hold your wrists on the steering wheel can prevent carpal tunnel.
In some cases, a wrist brace is helpful by taking pressure off the carpal tunnel.
Other suggestions include:
- Taking breaks when scheduled
- When driving, keep a safe, but looser grip on the steering wheel
- Keep your hands warm; cold is thought to contribute to, or aggravate symptoms
- Perform wrist stretches
Wrist Stretches
Performing wrist stretches to reduce tension and inflammation is another way to prevent carpal tunnel. The following are directions for exercises:
- Hand Squeeze
Use a stress ball and squeeze in the palm of your hand for a few seconds, and release. Repeat for each hand, five to ten times. - Wrist Extension
Extend your right arm forward and with your left hand, gently pull your right fingers pointed upwards towards you. Repeat for each arm, three to five times. - Wrist Flexion
Similar to the wrist extension stretch, but this time, point your fingers downward. Gently pull the fingers towards you. Repeat for each arm, three to five times. - Wrist Lift
Place your right hand, palm-side down, on a table or flat surface. Secondly, place the fingers of your left hand perpendicular over the top of your right hand. Make the motion to lift the palm of your right hand, but suppress the lift by pushing down with your left hand. Repeat for each hand, three to five times. - View Video Links
There are several video links available that also demonstrate these stretches.
