Carpal Tunnel Syndrome (CTS) is a repetitive-use injury that affects the carpal tunnel, a narrow passageway located in the wrist. This syndrome occurs when the median nerve, which runs through this tunnel, becomes compressed or irritated. Common symptoms include numbness, tingling, and weakness in the hand. Activities that can lead to CTS include prolonged keyboard use and repetitive wrist movements.
Causes of Carpal Tunnel Syndrome
Repetitive Motions
Continuous, repetitive movements of the wrist can cause inflammation, leading to increased pressure on the median nerve.
Medical Conditions
Conditions such as diabetes, rheumatoid arthritis, and thyroid disorders can contribute to the development of CTS.
Anatomical Factors
Certain anatomical differences, like a naturally narrower carpal tunnel, can predispose individuals to CTS.
Symptoms of Carpal Tunnel Syndrome
Initial Symptoms
- Numbness or tingling in the thumb, index, middle, and part of the ring fingers.
- Occasional discomfort in the wrist and hand.
Progressive Symptoms
- Increased frequency and intensity of numbness and tingling.
- Weakness in the hand, affecting the ability to grip objects.
- Chronic pain that may extend up the arm.
Diagnosis of Carpal Tunnel Syndrome
Diagnosis typically involves a physical examination, medical history review, and specific tests such as:
Nerve Conduction Studies
These studies measure the speed at which electrical impulses move through the median nerve.
Electromyography (EMG)
An EMG test assesses the electrical activity of muscles to detect nerve damage or nerve-muscle connectivity issues.
Treatment Options
Non-Surgical Treatments
Stretching and Strengthening Exercises
Regular exercises can help alleviate mild symptoms and prevent them from worsening.
Medications
Nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce inflammation and pain.
Wrist Splints
Wearing a wrist splint, particularly at night, can keep the wrist in a neutral position, reducing pressure on the median nerve.
Surgical Treatments
Carpal Tunnel Release Surgery
In severe cases, surgery may be necessary to alleviate pressure on the median nerve by cutting the ligament that forms the top of the carpal tunnel.
Prevention Strategies
Ergonomic Adjustments
Ensuring an ergonomically optimized workspace can prevent the onset of CTS. This includes adjusting the height of chairs, desks, and computer screens, and ensuring proper hand positioning while typing.
Regular Breaks and Exercises
Taking breaks to stretch and flex the hands and wrists can mitigate the risks of developing CTS.
Historical Context
Carpal Tunnel Syndrome has become increasingly prevalent with the rise of computer use, leading to greater awareness and improved ergonomic practices.

Summary
Carpal Tunnel Syndrome is a prevalent and often debilitating condition resulting from the compression of the median nerve within the carpal tunnel. Early diagnosis and treatment are crucial in managing symptoms and preventing long-term damage. With proper prevention strategies such as ergonomic adjustments and regular breaks, the risk of developing CTS can be significantly reduced.
