What is carpal tunnel syndrome?

Carpal tunnel syndrome is a condition that can cause numbness, tingling and sometimes pain and weakness to the hand. These symptoms occur when there is pressure in the wrist on a nerve called the median nerve. The median nerve provides sensation on the palm side of the hand to the thumb, index, and middle fingers, and most of the time to half of the ring finger. The median nerve also supplies the muscles in the palm on the thumb side of the hand. In severe cases you may see muscle atrophy or wasting of these muscles.  

Signs of carpal tunnel syndrome

The hallmark symptom of carpal tunnel syndrome is numbness at night and tingling/loss of sensation in the thumb, index, and middle fingers. Common issues with carpal tunnel syndrome include difficulty manipulating small objects, difficulty with holding and gripping items and difficulty with writing and keyboard use.  

The carpal tunnel itself if made up of the carpal bones of the wrist and the transverse carpal ligament. The carpal bones form a semi-circle, and the transverse carpal ligament is a very strong ligament that crosses the top of that semi-circle. The medial nerve travels inside this tunnel along with many tendons that allow us to move the wrist and fingers.  

Causes of carpal tunnel pain

Carpal tunnel syndrome is associated with activities such as repetitive use, high force gripping, vibration, and continuous use of the hands in extreme wrist range of motion, so it is not necessarily limited to keyboarding/work. Genetic factors can also influence the incidence of carpal tunnel syndrome as can past medical issues such as a wrist fracture.

What if it’s not carpal tunnel syndrome?

Carpal tunnel is often time confused with several other types of upper extremity conditions including cubital tunnel syndrome, De Quervain’s tenosynovitis, cervical radiculopathy, and Reynaud’s disease 

Treatment for carpal tunnel syndrome

If you feel like you may have carpal tunnel syndrome one of the first treatment approaches to relieve symptoms is to wear neutral wrist splints at night. Many people sleep with their wrist flexed for long periods of time at night. This can increase compression at the carpal tunnel causing irritation to the medial nerve. Neutral wrist splints help reduce compression at the carpal tunnel.  

Physical therapy can help reduce symptoms of carpal tunnel. Physical therapy for carpal tunnel typically consists of education on ways to reduce stress to the median nerve and upper extremity. Stretching exercises and strengthening activities may be prescribed to restore balance to the wrist and upper extremity. Tendon gliding activities and nerve gliding/flossing may be prescribed to help tissue heal. A physical therapist may visit your workplace to help reduce and modify activities that may be contributing to your symptoms.  

If conservative care fails, there are surgical options available for carpal tunnel syndrome. Physical therapy is beneficial following surgery for carpal tunnel in helping the patient with a smooth transition back to full function. This usually entails helping to reduce symptoms, so surgery followed by stretching to regain full range of motion and graded functional strengthening to get you back to all your normal activities.
