P 159 Long-time course of idiopathic small fiber neuropathy

Small fiber neuropathy (SFN) represents a subtype of peripheral neuropathies. As only small A-delta and C-fibers are involved patients suffer from typical clinical symptoms such as hypesthesia, burning and prickling sensations, temperature disturbance perception or autonomic symptoms without any signs of large fiber involvement. Thus electrophysiological examinations (sensory and motor nerve conduction studies (NCS), electromyography (EMG) and evoked potentials (EP)) do not elicit pathological findings as they indicate large fiber involvement.
