AB  - We studied the EMG response to loud noise in eight patients with stiff-man syndrome (SMS). Audiogenic muscle jerks originated in the acoustic startle reflex. Patients demonstrated excessive, poorly habituating motor activity predominately in axial and leg muscles. Exaggerated startle in SMS probably reflects segmental hyperexcitability of axial and lumbar spinal motor neurons.
