Understanding Carpal Tunnel Syndrome Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through the carpal tunnel in the wrist. The carpal tunnel is a narrow passage formed by wrist bones and a ligament. When this space narrows or contents swell, the median nerve becomes compressed, causing characteristic symptoms. Symptoms include numbness and tingling in the thumb, index, middle, and half of the ring finger. Symptoms often worsen at night. As the condition progresses, weakness develops, particularly in thumb opposition. Dropping objects and difficulty with fine motor tasks occur in advanced cases. Research from the Journal of Orthopaedic and Sports Physical Therapy shows that exercise and splinting are effective for mild to moderate carpal tunnel syndrome. A randomized trial found that physical therapy produced equivalent outcomes to surgery at one year for moderate cases. Early intervention produces better results. (PubMed) Contributing Factors Wrist position: Sustained wrist flexion or extension increases carpal tunnel pressure. Typing with wrists bent is a common contributor. Repetitive hand use: Assembly work, typing, and other repetitive hand activities increase risk. Systemic conditions: Diabetes, thyroid disorders, and rheumatoid arthritis increase carpal tunnel risk. Pregnancy: Fluid retention during pregnancy can cause temporary carpal tunnel symptoms. Start your 14-day free trial to access hand and wrist programs. Nerve Gliding Exercises These exercises help the median nerve move freely through the carpal tunnel. Wrist Flexion/Extension JME 200 Rotate your wrist both up and down while maintaining the same position of your forearm. Finger Spread JME 217 Starting with your hand in a relaxed position, extend all your fingers out to create as much space as possible. Wrist Circles JME 211 Holding onto both hands in front of your body, create circles with your wrists. Hand Opening JME 204 Open and close your hand. Wrist and Hand Strengthening These exercises build the strength to maintain proper wrist position. Wrist Rotation JME 208 With your arms out in front of you, rotate your palms both up and down. Finger Exercises JME 215 Keeping your fingertips in the same position, touch your thumb to each finger. Thumb Movement JME 214 Make a circle with your thumb by keeping your wrist and other fingers steady. Palm Press JME 202 Put your hands in a prayer position either in front of your face or chest - find a position that works for you. Splinting Night splints that hold the wrist in neutral position are effective for carpal tunnel. Wrist flexion increases carpal tunnel pressure. A splint prevents this during sleep when symptoms are often worst. Wear nightly for at least 3-4 weeks to assess benefit. Ergonomic Modifications Keyboard position: Type with wrists in neutral position, not bent up or down. Use a keyboard tray or adjust desk height as needed. Mouse use: Keep wrist neutral while using the mouse. Consider a vertical mouse or trackball. Breaks: Take regular breaks from repetitive hand activities. Stretch and move the hands every 20-30 minutes. Tool handles: Use padded handles that fit comfortably. Avoid gripping tightly. Common Mistakes Ignoring early symptoms: Early intervention produces better outcomes. Address symptoms when they first appear. Wrist rests misuse: Wrist rests should support during pauses, not during typing. Typing while resting on them can increase pressure. Aggressive stretching: Forcing wrist extension stretches can worsen nerve irritation. Gentle movement is better. Waiting too long: Severe carpal tunnel with significant weakness and muscle wasting may not fully recover with conservative treatment. When to Seek Help If symptoms do not improve with 4-6 weeks of conservative treatment, if muscle wasting is visible at the base of the thumb, or if symptoms are severe and constant, consult a healthcare provider. Nerve conduction studies can assess severity. Severe cases may benefit from surgical release. Progress Expectations Mild cases often improve within 2-4 weeks of splinting and exercise. Moderate cases take 6-12 weeks. Night symptoms typically improve first, followed by daytime symptoms. Continue exercises and ergonomic modifications to prevent recurrence.
