Neurology tests are conducted to diagnose peripheral neuropathy. Depending on patient’s symptoms, medical history and physical examination, various tests are recommended as diagnostic measure. Balaji Hospital also conducts the following tests:

• Electrodiagnostic tests- This measure the electrical activity of muscles and nerves. By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, non-invasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.

• Quantitative sensory testing (QST)- It is method for diagnosing peripheral nervous system disorders, including chronic pain and pain related to various diseases, such as Diabetes and CRPS. QST essentially determines the sensation and pain thresholds for cold and warm temperatures, and the vibration sensation threshold by stimulating the skin and comparing the results to normative values built in the software. When the stimulus activates stimuli-specific receptors; the nerve fibers that innervate the receptors communicate the stimuli’s message to the central nervous system, where feeling occurs.

• Autonomic testing- Autonomic tests measure how the systems in the body that are controlled by the autonomic nerves respond to stimulation. The data collected during testing will indicate if the autonomic nervous system is functioning as it should, or if nerve damage has occurred. This painless, non-invasive test helps to determine if a patient is suffering from certain diseases that attack the autonomic nervous system, or as a way to diagnose an illness, or source of pain.
