Carpal Tunnel Syndrome (CTS) is a condition where the median nerve becomes compressed as it passes through the wrist, primarily due to swelling of the tendons in the area. The median nerve controls muscles that move the thumb and sends sensory information to the brain. When compressed, this nerve can lead to:
- Pain in the wrist, hand, or fingers
- Aching, tingling, or numbness, especially in the thumb, index, and middle fingers
- Worsening symptoms at night, often disrupting sleep
Many individuals find that shaking the hand or letting it dangle out of bed can temporarily relieve the discomfort. If symptoms persist, a nerve conduction test can help confirm the diagnosis.
Common Causes and Risk Factors:
CTS is most often associated with repetitive wrist movements, particularly work-related activities such as typing or using vibrating tools. Other risk factors include:
- Arthritis affecting the wrist joint
- Thyroid disease or pregnancy, which can contribute to swelling and increased pressure on the median nerve
- High physical demands on the wrist due to frequent or forceful wrist motions
The risk is higher for individuals whose jobs involve prolonged repetitive motion, forceful tasks, or the use of vibrating tools.
How Physiotherapy Helps Manage Carpal Tunnel Syndrome
Physiotherapy is highly beneficial for managing mild to moderate CTS and can help alleviate pain, improve mobility, and prevent the condition from worsening. Treatment typically includes:
- Manual mobilization of the carpal bones: Techniques to gently move and realign the wrist bones to create more space for the median nerve.
- Stretching the flexor retinaculum: This ligament, which can tighten in CTS, is stretched to relieve pressure on the nerve.
- Wrist and hand exercises: These exercises aim to improve nerve motion and restore full range of movement.
- Muscle and soft tissue extensibility: Enhances flexibility to reduce tension and promote healing.
- Forearm and thumb strengthening: Focuses on strengthening the muscles around the wrist, improving grip and pinch strength.
- Education on hand dexterity and posture: Physiotherapists provide guidance on correct hand movements, posture, and fine motor exercises to reduce strain and prevent future flare-ups.
