Persistent developmental stuttering as a cortical-subcortical dysfunction: evidence from muscle activation.
BACKGROUND One contemporary view of stuttering posits that speech disfluencies arise from anomalous speech motor control. PURPOSE To verify the rest muscle tension and speech reaction time of fluent and stuttering adults. METHOD 22 adults, divided in two groups: G1--11 fluent individuals; G2--11 stutterers. Electromyography recordings (inferior orbicularis oris) were collected in two differ...

متن کاملNormal interhemispheric inhibition in persistent developmental stuttering.
Imaging studies suggest a right hemispheric (pre)motor overactivity in patients with persistent developmental stuttering (PDS). The interhemispheric inhibition (IHI) studied with transcranial magnetic stimulation is an established measure of the interplay between right and left motor areas. We assessed IHI in 15 young male adults with PDS and 15 age-matched fluent-speaking subjects. We addition...
متن کاملAltered functional connectivity in persistent developmental stuttering
Persistent developmental stuttering (PDS) is a speech disorder that impairs communication skills. Despite extensive research, the core causes of PDS are elusive. Converging evidence from task-induced neuroimaging methods has demonstrated the contributions of the basal ganglia and the cerebellum to PDS, but such task-state neuroimaging findings are often confounded by behavioral performance diff...
متن کاملQuality of life of individuals with persistent developmental stuttering.
BACKGROUND quality of life. AIM to verify the influence of the readiness of speech--regarding affective, behavioral and cognitive reactions--over the life quality of fluent individuals and those with persistent developmental stuttering (PDS). METHOD 40 adults divided in two groups, paired by gender and age. The research group (GI) consisted of 20 individuals with PDS, with no other associat...
