Carpal Tunnel Syndrome is a common condition that causes pain, numbness, and muscle weakness in the hand and arm due to compression of the median nerve as it passes through the carpal tunnel. It is the most common peripheral nerve disorder, especially in individuals who frequently perform repetitive hand movements.

1. Definition
Carpal Tunnel Syndrome occurs when the median nerve, which passes through the narrow carpal tunnel in the wrist, becomes compressed, leading to uncomfortable symptoms such as pain and numbness.
2. Causes
- Injury or inflammation: Inflammation or swelling in the wrist area due to injury, rheumatoid arthritis, or tendonitis.
- Overuse of the wrist: Repetitive hand movements such as typing, using a mouse, or lifting heavy objects.
- Hormonal disorders: Conditions like diabetes, pregnancy, and hypothyroidism can increase the risk of tissue swelling around the carpal tunnel.
- Genetics: Some people are born with narrower carpal tunnels, which increases the risk of developing the condition.
3. Symptoms and Signs
- Numbness and tingling: Usually felt in the thumb, index, middle finger, and part of the ring finger. These symptoms may worsen at night.
- Pain: Pain can radiate from the wrist up the forearm or down to the palm, sometimes extending to the shoulder.
- Muscle weakness: Difficulty gripping objects, with a noticeable loss of strength in the hand.
- Swelling sensation: Some people feel their fingers are swollen even when no actual swelling is present.
4. Complications
- Reduced hand function: If left untreated, carpal tunnel syndrome can lead to permanent nerve damage, resulting in impaired hand movement and sensation.
- Muscle atrophy: Muscle wasting at the base of the thumb due to prolonged loss of motor control and sensation.
- Decreased work capacity: Patients may experience difficulty performing daily tasks that require hand flexibility.
5. At-Risk Groups
- Office workers: Those who frequently use computers, keyboards, and mice.
- Factory workers: Individuals performing repetitive hand movements such as assembly, lifting, or operating machinery.
- Pregnant women: Due to hormonal changes and increased water retention in the body.
- Chronic illness patients: Those with a history of diabetes, obesity, or hypothyroidism.
- Elderly people: Aging increases the risk of musculoskeletal disorders.
Early detection and timely treatment of carpal tunnel syndrome can prevent serious complications and help maintain effective hand function in daily life.
