Knokkel

Knokkel, also known as the carpal tunnel, is a narrow passageway in the wrist that contains the median nerve and tendons. The median nerve runs from the forearm into the hand, and the carpal tunnel is the point where it passes through the wrist bones. The tendons in the carpal tunnel are responsible for the movement of the thumb and the first two fingers. The carpal tunnel syndrome (CTS) is a condition that occurs when the median nerve is compressed or irritated, leading to symptoms such as pain, numbness, tingling, and weakness in the hand and fingers. The most common cause of CTS is repetitive hand movements, such as those involved in typing, writing, or using tools. Other causes include pregnancy, arthritis, diabetes, and certain medications. Symptoms of CTS typically begin gradually and worsen over time. They may include pain or discomfort in the wrist and hand, particularly at night or when using the affected hand. Numbness, tingling, or weakness in the thumb, index finger, and middle finger may also occur. In severe cases, the hand may feel "asleep" or "fall asleep" during use. Diagnosis of CTS is usually based on a physical examination and medical history. Imaging tests, such as an MRI or ultrasound, may be used to confirm the diagnosis. Treatment options for CTS include rest, splinting, physical therapy, medications, and in some cases, surgery. Rest and splinting can help reduce pressure on the median nerve. Physical therapy can help strengthen the hand and improve function. Medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may help reduce inflammation and pain. In severe cases, surgery may be recommended to relieve pressure on the median nerve. Prevention of CTS involves avoiding repetitive hand movements, using ergonomic tools and equipment, and maintaining a healthy lifestyle.
