Relationship between stuttering severity and brainstem-evoked response testing.
Brainstem-evoked-response testing was performed on 8 adult stutterers and 8 non-stutterers. Stutterers demonstrated prolonged central conduction time as measured by the interpeak latency (IPL) differences between Waves I to V. Five of the stutterers manifested abnormalities unilaterally, while three of the subjects showed abnormal responses bilaterally. No relationship was found between brainstem-evoked-response testing and severity of stuttering.
