In point of fact, the most common presentation of diabetic neuropathy is small-fiber, as is the most common presentation of idiopathic neuropathies. These can be detected through specialized types of testing-sudomotor axon reflex testing, qualitative sensory testing, and (the current gold standard) skin biopsy to enumerate intraepidermal nerve fiber density and condition. But these tests will generally only show gross levels of damage, and not right away-it often takes weeks following an injury or disease process to damage the nerves enough for abnormal results to become apparent.Īnd, more importantly, EMG and nerve conduction studies cannot detect certain types of neuropathy-those that preferentially affect the small, non-myelinated nerves that subsume the sensations of pain and temperature and also control many autonomic functions. Abnormal results on these do point to some form of neuropathy-at least of those nerves. EMG and nerve conduction studies only measure larger, myelinated nerves.
