Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) is the most common peripheral nerve compression disorder, affecting an estimated 3–6% of the general adult population. It occurs when the median nerve is compressed within the carpal tunnel of the wrist, causing pain, numbness, and weakness in the hand and fingers. With early intervention — including wrist splinting — most patients can manage symptoms and avoid surgery.

Common Causes of Carpal Tunnel Syndrome

• Repetitive hand and wrist motions (typing, assembly work, tool use)
• Wrist flexion during sleep, putting pressure on the median nerve
• Inflammatory conditions such as rheumatoid arthritis
• Pregnancy-related fluid retention
• Diabetes, hypothyroidism, and other metabolic disorders
• Direct trauma or fractures to the wrist

Common Symptoms:

• Numbness and tingling in the thumb, index, middle, and ring fingers
• Nighttime pain and “electric shock” sensations in the hand
• Weakness in grip strength and difficulty pinching
• Burning or aching sensation traveling up the forearm
• Dropping objects due to loss of fine motor control
• Swelling sensation in the fingers (even when none is visible)

How Is Carpal Tunnel Syndrome Treated?

• Neutral-position wrist splinting (especially at night)
• Corticosteroid injections to reduce inflammation
• Ergonomic modifications to workstation and tools
• Occupational therapy and stretching exercises
• Non-steroidal anti-inflammatory drugs (NSAIDs)
• Carpal tunnel release surgery (severe or refractory cases)
• Yoga and nerve-gliding exercises
• Activity modification and rest

How a Wrist Splint Helps Carpal Tunnel Syndrome:

Keeping the wrist in a neutral or slightly extended position reduces pressure on the median nerve, relieving nighttime symptoms and preventing further nerve damage during daily activities. RCAI’s wrist splints are constructed with a rigid palmar stay that maintains proper alignment while allowing full finger freedom. Many patients experience significant symptom relief within weeks of consistent splint use, making bracing a first-line conservative treatment recommended by the American Academy of Orthopaedic Surgeons.
