How is carpal tunnel syndrome diagnosed?
-
First, a doctor will usually evaluate your reported symptoms and examine your hand and wrist. One clue to diagnosis is that the median nerve-the nerve that causes carpal tunnel syndrome-does not affect the little finger, so pain or numbness in that finger can indicate another condition. If your doctor suspects carpal tunnel syndrome based on your symptoms, a nerve test may be recommended. Usually, tests for carpal tunnel syndrome will include measuring the electrical activity in your hand muscles.

Debra Fulghum Bruce PhD answered:Your doctor can diagnose carpal tunnel syndrome after a complete physical examination and review of your medical history. Your doctor will notice the type of pain you have and the specific places on your hand. Tests including an electrical nerve conduction test may be helpful in obtaining an accurate diagnosis. With carpal tunnel syndrome, x‑rays and blood tests are usually normal. Depending on the exact cause, treatment may include nonsteroidal anti-inflammatory drugs (NSAIDs), along with a splint for your wrist, a local injection of cortisone to reduce the swelling around the nerve or possibly a minor outpatient surgical procedure.

Dr. Michael E. Raemisch of Intermountain Healthcare answered:Most often, carpal tunnel syndrome can be diagnosed by history (the description of the pains the patient is experiencing), and physical exam (what the doctor finds looking at your hand during your visit). Stereotypical symptoms include numbness and tingling in the thumb, index and middle fingers, and occasionally the ring finger. This numbness is usually associated with a "pain" in the hand that can be very difficult for patients to describe. While carpal tunnel syndrome is a nerve problem, some patients describe it as their hand "doesn't get enough blood flow". Many people with carpal tunnel will shake their hand to "get the blood flow back". At times, the pain may be severe enough to keep a person up at night.

Dr. Vonda Wright answered:Carpal tunnel syndrome involves compression of a nerve, called the median nerve, as it travels through the wrist. Diagnosis is based on a combination of patient history, physical exam and nerve testing. Typical symptoms include numbness and tingling in the thumb, index and middle fingers. More severe forms include weakness in certain hand muscles. Your physician can do certain special physical exam tests that may reproduce some of your symptoms. Your physician may also send you to get nerve conduction testing which can calculate the severity of nerve injury.Carpal tunnel syndrome involves compression of a nerve, called the median nerve, as it travels through the wrist.

Dr. Rachel Rohde answered:Diagnosis is made by history and examination by your doctor. If there is a history of injury, X-rays can determine if there are any bony reasons for the symptoms. A nerve conduction study (NCV) and/or electromyogram (EMG) is not always needed might be performed to confirm the diagnosis and to check for other nerve problems.

Durkan carpal tunnel compression test: A doctor will press down on the median nerve in the wrist to determine whether the pressure causes the patient to experience any numbness or tingling in the wrists.
Electrophysiological tests: Nerve function is tested with electrical stimulation when symptoms persist. Additionally, this test can help to confirm the diagnosis and determine the best treatment option.
Phalen maneuver: This test is also known as wrist-flexion and requires patients to hold their forearms upright by pointing the fingers down and pressing the backs of the hands together. Carpal tunnel syndrome may be present if one or more symptoms (i.e. tingling or increasing numbness) occur(s) within one minute.
Thumb abduction strength test: The doctor may straighten the thumb while it is being held to reveal signs of weakness in the median nerve.
Tinel Sign: The doctor may tap on the patient's wrist with a reflex hammer. A positive test means that the patient experiences a tingling in the fingers or a shock-like sensation.You should read product labels, and discuss all therapies with a qualified healthcare provider.

Healthwise answered:Carpal tunnel syndrome is usually diagnosed using:
- Medical history. The doctor will ask about any medical problems or illnesses, prior injuries, current symptoms or daily activities that may be causing your symptoms.
- Hand diagram. You may be asked to help fill in a diagram of your hand to show where you have numbness, tingling or pain.
- Physical exam, including comparing the strength of both hands.
If your symptoms are severe, if nonsurgical treatment has not improved symptoms or if your symptoms aren't clearly caused by carpal tunnel syndrome, your doctor may recommend:
- Nerve testing, which checks the median nerve.
- X-rays. These can check for bone problems caused by past injury, arthritis, recently broken or dislocated bones or tumors. X-rays aren't used to diagnose carpal tunnel syndrome. But they can be helpful for finding signs of arthritis or an old or new wrist or neck injury that may be adding to your symptoms.
- Ultrasound, to look at the size of the median nerve. It is inexpensive, comfortable and quick. But its use for carpal tunnel syndrome diagnosis is still unproven and fairly uncommon.
- MRI. This imaging test can find swelling of the median nerve, narrowing of the carpal tunnel or problems with circulation of blood through the carpal tunnel.
- Blood tests. These are sometimes done to check for a thyroid problem, rheumatoid arthritis, or another medical problem.

Riverside Center for Neurosciences answered:Early diagnosis and treatment are important to avoid permanent damage to the median nerve. A physical examination of the hands, arms, shoulders, and neck can help determine if the patient's complaints are related to daily activities or to an underlying disorder and can rule out other painful conditions that mimic carpal tunnel syndrome. The wrist is examined for tenderness, swelling, warmth, and discoloration. Each finger should be tested for sensation, and the muscles at the base of the hand should be examined for strength and signs of atrophy. Routine laboratory tests and X-rays can reveal diabetes, arthritis, and fractures.
Physicians can use specific tests to try to produce the symptoms of carpal tunnel syndrome. In the Tinel test, the doctor taps on or presses on the median nerve in the patient's wrist. The test is positive when tingling in the fingers or a resultant shock-like sensation occurs. The Phalen, or wrist-flexion, test involves having the patient hold his or her forearms upright by pointing the fingers down and pressing the backs of the hands together. The presence of carpal tunnel syndrome is suggested if one or more symptoms, such as tingling or increasing numbness, is felt in the fingers within one minute. Doctors may also ask patients to try to make a movement that brings on the symptoms.
Often, it is necessary to confirm the diagnosis by using electrodiagnostic tests. In a nerve conduction study, electrodes are placed on the hand and wrist. Small electric shocks are applied and the speed with which the nerves transmit impulses is measured. In electromyography, a fine needle is inserted into a muscle; the viewing of electrical activity on a screen can determine the severity of damage to the median nerve. Ultrasound imaging can show impaired movement of the median nerve. Magnetic resonance imaging (MRI) can show the anatomy of the wrist but to date has not been especially useful in diagnosing carpal tunnel syndrome.
