Sensory conduction velocity of median and sural nerves was examined in 6 patients with spinal muscular atrophy (SMA) of Kennedy type. In all patients, except the youngest one, slight slowing of sensory conduction velocity and marked decrease of potential amplitude was observed. These changes might suggest that the Kennedy type of SMA differs from another types of SMA and, may be, does not fit into "pure" motoneuron disease.
