Stuttering children and the probability of remission--the role of cerebral dominance and speech production.
OBJECTIVE
The identification of critical characteristics which might predict whether childhood stuttering will become chronic. Part of the study investigates the relationship between hearing and central processing of acoustic stimuli, cerebral dominance and the clinical course of the stuttering.


METHODS
A prospective study of 79 stuttering children aged 3-9 years. The subjects were examined with regard to their cerebral dominance in various tests of laterality, their peripheral hearing and their ability to discriminate sound using the dichotic discrimination test according to Uttenweiler (V. Uttenweiler, Dichotischer Diskriminationstest für Kinder, Sprache Stimme Gehör 4 (1980) 107-111). Results were correlated with the probability of remission of stuttering. Comparisons were made with a control group of 18 children of kindergarten age with normal speech. The period of investigation was 18 months.


RESULTS
Seventy-two children underwent follow-up examinations. Of these, 36 achieved fluency of speech. The results of the dichotic discrimination test showed no relation to the rate of remission. When the relationship between handedness and stuttering was investigated, it was found that left-handed children had a significantly poorer chance of attaining speech fluency.


CONCLUSIONS
The Uttenweiler test allowed no prognostic evaluation of the future course of stuttering in the age group studied, though auditory dominance was not completely developed in a majority of the 3-6 year-old children. Handedness, however, appears to be related to the probability that stuttering will become chronic.
