Carpal Tunnel Syndrome

Carpal Tunnel Syndrome (CTS) is a repetitive-use injury of the carpal tunnel, a nerve pathway in the wrist, frequently seen in individuals who spend extended periods keyboarding and using a mouse. It can cause numbness, tingling, and pain in the hand. Preventive measures such as stretching and taking regular breaks can help mitigate the risk of CTS.

Definition

Carpal Tunnel Syndrome (CTS) is a condition caused by pressure on the median nerve as it travels through the carpal tunnel in the wrist. This compression leads to symptoms such as numbness, tingling, weakness, or pain in the hand and fingers. CTS is commonly associated with repetitive movements or prolonged use of the wrist, particularly during activities like typing and using a mouse.


Symptoms and Causes

Common Symptoms

  • Numbness or tingling in the thumb, index, middle, and ring fingers.
  • Pain or discomfort in the hand and wrist.
  • Weakness in the hand, making it difficult to hold objects or perform fine motor tasks.
  • A sensation of swelling in the fingers, even if no visible swelling is present.

Common Causes

  • Repetitive hand movements (e.g., typing, mouse use).
  • Prolonged wrist positioning in flexion or extension.
  • Inflammatory conditions such as rheumatoid arthritis.
  • Medical conditions such as diabetes or hypothyroidism.
  • Pregnancy-related fluid retention.

Examples

Office Workers

Employees whose jobs involve prolonged computer use, particularly intense keyboarding and mouse usage, are at a high risk of developing CTS.

Assembly Line Workers

Workers engaged in repetitive assembly line tasks involving hand movements may also be prone to CTS due to repetitive strain on the wrist.

Musicians

Musicians, especially those who play instruments that require frequent and repetitive hand movements like guitarists or pianists, may experience symptoms of CTS.


Frequently Asked Questions (FAQs)

What are the early signs of Carpal Tunnel Syndrome?

Early signs include numbness or tingling in the hand, especially in the thumb, index, and middle fingers, and sometimes weakness in holding objects.

How can I prevent Carpal Tunnel Syndrome?

Take frequent breaks to stretch your hands and wrists, maintain proper wrist posture, use ergonomic keyboard and mouse setups, and perform hand and wrist exercises regularly.

When should I see a doctor?

If you experience persistent numbness, tingling, or pain in your hand that does not improve with rest and over-the-counter treatments, you should consult a medical professional.

Is surgery the only option for treating Carpal Tunnel Syndrome?

Surgery is usually considered when symptoms are severe or have not improved with other treatments such as wrist splinting, medication, and physical therapy.

Can Carpal Tunnel Syndrome be cured?

Many people find relief through conservative treatments and lifestyle changes. However, some cases may require surgical intervention for symptom relief.


Ergonomic Keyboard

A keyboard designed to minimize strain on the hands and wrists and reduce the risk of repetitive stress injuries like CTS.

Median Nerve

The nerve that runs down the arm and forearm to the hand, which becomes compressed in CTS.

Repetitive Strain Injury (RSI)

A condition resulting from repetitive motion and overuse, which can affect various parts of the body, including the wrists and hands.

Wrist Splint

A brace used to keep the wrist in a neutral position to reduce pressure on the median nerve and alleviate CTS symptoms.
