The tests can typically be done in less than an hour. These tests are usually administered by a neurologist (a doctor who specializes in the study of the nerves) or a physiatrist (a physical medicine and rehabilitation, or PM&R, specialist). This process is called electrodiagnostic testing. If you have pain, weakness, or numbness in your back, neck, or limbs, measuring the speed and degree of electrical activity in your muscles and nerves can help your doctor make a proper diagnosis. Injuries or diseases that affect nerves and muscles can slow or halt the movement of these electrical signals. Motor nerves deliver signals from the brain to activate your muscles.Sensory nerves deliver information about your surroundings to the brain.120-124.Did you know that your body is an electrical generator? Nerves and muscles create electrical signals that deliver messages to and from your brain.

In later stages, patients may develop motor deficits of the median nerve with associated weakness of the thenar muscles leading to impaired pinch and grip of the hand.

Sensory symptoms tend to occur with repetitive hand movements, sustained hand/ wrist postures, and often worsen at night. Rarely, patients may also report pain radiating proximally from the wrist towards the elbow. Įarly in the disease course, clinical features revolve around sensory deficits of the median nerve, with associated paresthesia, pain, and/or numbness in the palmar surface of the thumb, index, middle, and radial half of the ring finger. The median nerve has both motor and sensory functions, which can be affected in carpal tunnel syndrome. The pathophysiology involves increased pressure on the median nerve as it traverses through the carpal tunnel leading to impaired blood flow, inflammation, and ischemic injury of the nerve. Carpal Tunnel Syndrome is the most common nerve entrapment syndrome, affecting approximately 3.8% of the general population.
