[Physiopathology of the Holmes-Adie syndrome. Neurophysiological examinations of the autoreflex disorder].

Areflexia of 8 patients with Holmes-Adie-syndrome was investigated. The voluntary movements, electromyograms, motor and sensory nerve conduction velocities and the nerve action potentials were normal. The mechanically elicited afferents of mechanoreceptors of the soleus muscle (recorded with semimicro-electrodes) were not different in Holmes-Adie-patients with areflexia and normals.
