What Stretches Can I Do for Carpal Tunnel?

Introduction

Carpal tunnel syndrome (CTS) is a common nerve disorder that affects millions of people worldwide. It is characterized by pain, numbness, tingling, and weakness in the hand and wrist. CTS arises when the median nerve is compressed as it passes through the carpal tunnel, a narrow passageway in the wrist. Modern lifestyles, repetitive motions, and prolonged computer use are leading causes, making it increasingly prevalent. Incorporating specific stretches into your daily routine can help relieve carpal tunnel symptoms, improve mobility, and prevent further issues.

Understanding Carpal Tunnel Syndrome

Anatomy of the Carpal Tunnel

The carpal tunnel is a narrow, rigid passageway at the base of the hand, bounded by bones and ligaments. The median nerve, along with several tendons, passes through this tunnel. When the tunnel becomes swollen or narrowed, pressure on the median nerve increases, leading to CTS symptoms.

Common Symptoms

• Numbness and tingling: Frequently felt in the thumb, index, middle, and ring fingers.
• Weakness: Difficulty gripping or holding objects.
• Pain: Discomfort or aching in the wrist, hand, or forearm, sometimes radiating up the arm.

Risk Factors

• Repetitive hand movements (typing, assembly work)
• Pregnancy or hormonal changes
• Medical conditions (diabetes, arthritis, hypothyroidism)
• Obesity
• Family history of CTS

How Stretching Helps

• Role of flexibility and mobility: Stretching helps maintain flexibility in the wrist, hand, and forearm, reducing stiffness and discomfort.
• Reducing pressure on the median nerve: Gentle stretches relieve pressure by increasing the mobility of tissues surrounding the nerve.
• Enhancing blood flow and improving function: Stretches promote circulation, helping reduce inflammation and support healing of irritated tissues.

General Precautions Before Stretching

• When to consult a healthcare professional: Speak with your doctor before starting a stretching routine if your symptoms are severe or worsening.
• Signs to stop exercising: If you feel sharp pain, increased numbness, or weakness, stop immediately and seek medical advice.
• Importance of gentle movements: Perform each stretch slowly and gently. Avoid overstretching, which can further aggravate symptoms.

Wrist and Hand Stretches

Wrist Flexor Stretch

1. Extend your affected arm in front of you with palm facing up.
2. With your other hand, gently bend your wrist down, pointing fingers toward the floor.
3. Hold for 15-30 seconds. Feel a stretch along the inside of your forearm and wrist.
4. Repeat 2–3 times on each hand.

Benefits: Relieves tension in the wrist flexors and helps decrease pressure in the carpal tunnel.

Wrist Extensor Stretch

1. Extend arm with palm facing down.
2. Use your opposite hand to gently bend your wrist so fingers point down.
3. Hold for 15-30 seconds. Stretch should be felt on the top of your forearm and wrist.
4. Repeat 2–3 times on each hand.

Benefits: Increases flexibility in wrist extensors, countering repetitive flexion motions.

Prayer Stretch

1. Sit or stand with your palms pressed together in a praying position at chest level.
2. Lower your hands toward your waistline, keeping them pressed together.
3. Stop when you feel a gentle stretch in the wrists and forearms.
4. Hold for 15-30 seconds, repeat 2–3 times.

Benefits: Opens up the carpal tunnel space and stretches multiple forearm muscles.

Reverse Prayer Stretch

1. Place the backs of your hands together in front of your chest, fingers pointing down.
2. Gently press hands together, raising toward chest height as comfort allows.
3. Hold for 10-20 seconds, repeat 2–3 times.

Benefits: Stretches tendons on the backs of the hands and wrists, promoting balance.

Nerve Gliding Exercises

Median Nerve Glide Exercise

What is nerve gliding? Nerve gliding exercises gently mobilize the median nerve through the carpal tunnel, reducing adhesions and improving nerve health.

1. Start with your arm extended by your side and your palm facing up.
2. Slowly bend the elbow, bringing your palm toward your face like holding a tray.
3. Straighten your fingers, gently stretch your wrist backward and move your palm away from you.
4. Hold briefly and return to the starting position.
5. Repeat 5–10 times, moving gently.

Cautions: Avoid forcing your wrist or fingers. Stop if you feel tingling or pain.

Tendon Gliding Exercise

1. Start with your fingers and thumb straight.
2. Make a hook fist (bend knuckles but keep middle and end joints straight).
3. Form a full fist, then a straight fist (bend all knuckles).
4. Return to starting position each time.
5. Repeat each movement 5–10 times.

Cautions: Move slowly and stop if you experience increased pain or numbness.

Thumb and Finger Stretches

Thumb Stretch

1. Hold your hand out, palm up.
2. Use your other hand to gently pull your thumb away from your palm.
3. Hold for 15-30 seconds, feeling a stretch along your thumb and wrist.
4. Repeat 2–3 times on each hand.

Benefits: Alleviates stiffness in the thumb area, crucial for grip and pinching.

Finger Extension and Flexion

1. Straighten all your fingers, spreading them apart.
2. Squeeze your hand into a gentle fist and then release to straight extension.
3. Repeat 10–15 times.

Benefits: Improves flexibility and movement in the finger joints, reducing stiffness from CTS.

Additional Stretching Tips

• Perform each stretch 1-3 times a day for best results.
• Hold each stretch for 15–30 seconds, unless otherwise indicated.
• Integrate stretches into your daily routine: during work breaks, after using devices, or before bed.
• If needed, use wrist splints to support proper alignment, especially at night.

Complementary Approaches

• Ergonomic adjustments: Ensure your workspace supports proper wrist alignment to reduce CTS risk.
• Strengthening exercises: Gradual strengthening of hand, wrist, and forearm muscles can provide long-term support.
• Rest and activity modification: Take frequent breaks, avoid prolonged gripping, and rest your hands as needed.

When to Seek Professional Help

• If symptoms persist or worsen despite proper stretching and modifications.
• Experiencing more severe signs of nerve compression: significant weakness, muscle wasting, or persistent numbness.
• Physical therapy can provide targeted exercises and hands-on techniques for optimal recovery.

Conclusion

Consistently performing gentle stretches can relieve carpal tunnel symptoms, improve function, and prevent further complications. Making stretching a regular habit, alongside proper ergonomics, can significantly enhance hand and wrist comfort. Always consult a healthcare provider with concerns or if symptoms persist.
