Abstract
The authors continuously measured maximum blood pressure of 28 adult stutterers and 10 adult non-stutterers. Results obtained were as follows: 1. Maximum blood pressure of the non-stutterers, even if they imitated to stutter, showed no excessive change and remained to the stable state. The pressure was not influenced by speaking and reading. 2. When the stutterers were subjected to psychological stress in speaking and reading, three patterns of changes occurred in their maximum blood pressure. 3. There was high correlation between the stuttering type and the pattern of maximum blood pressure changes. Maximum blood pressure of the hesitating type person and the spastic type person showed excessive changes. In the blocking type person, changes of the pressure was not so excessive. 4. As the stuttering therapy proceeds and the stutterers become to be able to tolerate the psychological stress, changes in maximum blood pressure diminish. 5. From the clinical point of view in stuttering, it is meaningful to measure continuously the blood pressure of the stutterers. 6. By measuring continuously the blood pressure, we could screen the stutterers and further classify them to several types objectively.
