Stutterers exhibit subclinical tremors in extremity muscles at rest. These tremors, observed in non-speech muscles, suggest motor feedback system dysfunction, particularly in the extrapyramidal and cerebellar pathways.

Area of Science:

  • Neurology
  • Speech-Language Pathology
  • Motor Control

Background:

  • Stuttering is a speech disorder often associated with neurological factors.
  • Subclinical motor abnormalities may precede or accompany speech disfluencies.

Purpose of the Study:

  • To investigate the presence of subclinical tremors in the extremity muscles of individuals who stutter.
  • To explore the potential link between these tremors and motor control mechanisms.

Main Methods:

  • Electromyography (EMG) was used to record muscle activity.
  • Tremor analysis was performed on the musculus abductor digiti quinti during isometric contraction in stutterers at rest.

Main Results:

  • Subclinical tremor activity was detected in the abductor digiti quinti muscle of stutterers.

  • The tremor was present even when the individuals were at rest and not speaking.

    • Conclusions:

    • The observed tremor is unlikely to be an exaggeration of physiological tremor.
    • Findings suggest alterations in motor feedback structures, specifically within the extrapyramidal and cerebellar systems, may underlie stuttering.
