    Area of Science:

    • Speech-language pathology
    • Neuroscience
    • Biofeedback technology

    Background:

    • Stuttering is a complex speech disorder affecting fluency.
    • Laryngeal muscle tension is often associated with stuttering.
    • Biofeedback offers potential therapeutic avenues for speech disorders.

    Observation:

    • A single patient with stuttering was studied.
    • Auditory feedback was provided related to laryngeal muscle tension.
    • Electromyography (EMG) signals measured muscle activity.

    Findings:

    • Auditory feedback dramatically reduced stuttering severity.
    • EMG signal amplitude, reflecting muscle tension, was significantly lowered.
    • The therapeutic benefits were not due to masking, distraction, or suggestion.

    Implications:

    • Auditory biofeedback may be an effective treatment for stuttering.
    • Targeting laryngeal muscle tension with biofeedback shows promise.
    • Further research is warranted to explore this intervention in larger populations.
