Risk Factors

Women and older adults are at greater risk for carpal tunnel syndrome.
Factors that may increase your risk of carpal tunnel syndrome include:
 

Diagnosis

You will be asked about your symptoms and medical history. A physical exam of your arms, wrists, and hands will be done. The exam will include tests of strength, sensation, and signs of nerve irritation or damage.
Other tests may include:
  • Electrodiagnostic exam —Measures and records the speed of electrical conduction in your median nerve to see if the nerve impulse in the hand is delayed
  • MRI scan —A test that uses magnetic waves to make pictures of structures inside your body, in this case the neck
  • X-ray —A test that uses radiation to take a picture of structures inside your body, especially bones
  • Ultrasound—A test that uses sound waves to measure the width of your median nerve (may be used as a screening test or to guide injections)
