Carpal Tunnel Syndrome

To set up an ergonomic evaluation, please contact the Medical Department at x2281.

Carpal Tunnel Syndrome (CTS) is a frequent and painful disorder of the wrist, caused by bad posture, excessive force, or repeated hand movement without a break. The nerves and tendons that pass from the arm into the hand through the carpal tunnel can get pressed against the bone causing nerve entrapment. Nerve entrapment symptoms can also be caused by dislocated or fractured bones; diseases such as diabetes mellitus, arthritis, and hypothyroidism; or fluid retention (as in pregnancy ). People who are at increased risk of developing CTS include dentists, piano players, typists, and people who play racket sports.

Initial symptoms of CTS (burning, tingling, and numbness of the hand that can cause someone to awaken at night) can progress to a weakened grip and severe pain in the arm. If you encounter any of these symptoms, get medical advise before the disease progresses. Once diagnosed, doctors may perform nerve conduction tests to check for nerve damage or may recommend surgery if the muscle damage is severe. Surgery is usually successful in restoring hand function unless the condition has been present for several years.

If you do not yet show signs of CTS, you can reduce your chances of developing it by following some simple steps.

• Observe good posture at all times.
• Do warm-up exercises.
• Use an alarm clock to remind you to change tasks every hour.
• Keep your wrist straight or at a neutral position.
• Type with a soft touch -- don't pound the keys.
• Avoid working in the cold, when circulation to the hands may be decreased.
• Stop any activity that causes pain -- pain is a signal that you should ease up.

If you already have CTS, you may have to make adjustments in your job or lifestyle that will help to reduce the symptoms.

• Take rest periods or task breaks every hour.
• Avoid caffeinated drinks and cigarettes.
• Use anti-inflammatory medications (such as aspirin, ibuprofen, and cortisone injections) and cold compresses to relieve pain and reduce swelling in the affected area.
