![]() ![]() Pronator teres syndrome (PTS) differs from carpal tunnel syndrome as it occurs when the median nerve is compressed in the upper forearm rather than in the wrist and hand. A small shock to your median nerve is passed through two electrodes taped to your skin to see if electrical impulses are slowed within the carpal tunnel. ![]() The other test is a nerve conduction study, a variation on electromyography. This test reveals damage to the muscles controlled by the median nerve. A thin needle electrode is inserted to observe electrical activity when the muscles are contracting and when they’re at rest. One test is electromyography, which measures small electrical discharges produced by your muscles. Two other diagnostic tests are the main ones used. X-rays are sometimes ordered, but only to rule out other causes. The doctor will manually bend your wrist, tap on the area of your median nerve, or just press on it, as it’s likely to trigger your symptoms. Your doctor will test the feeling in your fingers and the strength of the muscles in your hand. Your doctor will go over a history of your symptoms, look for patterns, and perform a physical exam. It can also lead to dropping things because your hand goes numb or your thumb’s pinching muscle becomes weak, as the median nerve controls both. Carpal tunnel syndrome can lead to weakness when picking up, holding, or grasping objects. Sufferers of carpal tunnel syndrome may attempt to stop the numbness and tingling or shock-like sensations by shaking out their hands, but in time the numbness can become constant as the syndrome progresses. They’re most likely to occur while sleeping, holding a phone, a steering wheel, typing, using a mouse or touchpad, and writing. Sensations can also travel from your wrist up to your arm. You may feel a sense of electric shock through your thumb and the affected fingers. Symptoms usually begin gradually, with the most tingling and numbness affecting the thumb, index, middle and ring finger and occasionally the little finger. The symptoms of carpal tunnel syndrome can include numbness, tingling, and weakness in the hand and arm. What are the Symptoms of Carpal Tunnel Syndrome? ![]() This compression affects the sensation and function of your wrist, hand, and fingers. Carpal tunnel syndrome arises when your median nerve becomes compressed, meaning there’s pressure on your median nerve. The median nerve originates in your spinal cord, then goes down the front of your arm and forearm, and into your hands and fingers. Carpal tunnel is also referred to as median nerve compression. Your carpal tunnel is a narrow pathway on the palm side of your hand that your ligaments and bones surround. ![]()
