Abstract:
jective To study the clinical and electrophysiological characteristics of sensory axonal neuropathy (SAN). Methods Clinical data in 24 patients with SAN and 88 age-matched normal controls were examined. Sensory and motor nerve conduction were evaluated with supramaximal stimulation and surface electrodes in 180 nerves at different nerve segments of normal subjects, and compared with that of 90 nerves with sensory axonal neuropathy. Results Sensory symptoms of numbness and sensory ataxia were seen in 91. 6% of the patients, 70. 8% of them were mainly involved in the lower extremities. No weakness and fasciculation were found in our patients. Nerve conduction studies showed a normal MCV and CMAP amplitude, but the decreased amplitude of SNAP and slowed SCV in our patients had significant differences as compared with that of the normal subjects (P
