Carpal tunnel syndrome (CTS) is a common condition that affects the hand and wrist, leading to symptoms such as numbness, tingling, and weakness in the affected area. Understanding what causes carpal tunnel syndrome is crucial for both prevention and treatment.
What is Carpal Tunnel?
Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm, becomes pressed or squeezed at the wrist. The carpal tunnel—a narrow, rigid passageway of ligaments and bones at the base of the hand—houses the median nerve and tendons. Sometimes, thickening from irritated tendons, or other swelling, narrows the tunnel and can cause the median nerve to be compressed. The result may be pain, weakness, or numbness in the hand and wrist, radiating up the arm.
Common Causes of Carpal Tunnel
Several factors can contribute to the development of CTS. The condition is often the result of a combination of factors, rather than a single problem.
1. Repetitive Hand and Wrist Movements
Repeatedly performing the same hand and wrist movements can lead to swelling of the tendons in the carpal tunnel. Activities that involve extensive typing, writing, or use of power tools can worsen this condition.
2. Awkward Wrist Positions
Holding your wrist in an awkward or unnatural position for prolonged periods, such as when typing on a keyboard that’s not ergonomically positioned, can increase the risk of CTS. Such positions can put additional pressure on the median nerve.
3. Anatomical and Hereditary Factors
Some people are born with a smaller carpal tunnel or may have anatomical differences that change the amount of space for the nerve—and these traits can be genetic. This inherent predisposition can increase the chances of developing CTS.
Other Causes of Carpal Tunnel
Medical Conditions
Certain medical conditions can contribute to the development of CTS. These include:
- Rheumatoid arthritis
- Diabetes
- Thyroid gland imbalances
These can affect the body’s nerves and lead to swelling within the carpal tunnel.
Pregnancy
Hormonal changes during pregnancy can cause swelling in the body, including the carpal tunnel, leading to CTS. This type of CTS is often temporary and resolves after pregnancy.
Lifestyle Factors
Increased weight, smoking, and even your nutrition may all increase the risk of developing CTS. Similarly, workplaces that have poor ergonomics or require repetitive hand movements can increase the likelihood of developing symptoms.
How to Make Desk Work More Comfortable
Unfortunately, CTS can affect anyone, but it is commonly seen in desk workers due to constant, repetitive typing. Fortunately, there are ways to help reduce your risk of developing or worsening carpal tunnel syndrome. Try these three tips that can help bring a little more comfort and reduce tension at your desk!
Understanding the many causes of carpal tunnel syndrome is the first step toward prevention and effective treatment. Whether it’s making lifestyle adjustments, changing your work setup, or seeking medical advice for underlying conditions, intervention is key.
If you’re experiencing symptoms of carpal tunnel syndrome or any other wrist-related conditions, schedule an appointment with an Airrosti Provider! You’ll be given a thorough examination and diagnosis, in addition to hands-on manual therapy, to help fix your pain fast.
