    Spastic dysphonia, a voice disorder, can stem from abnormal muscle activity. Biofeedback therapy effectively treated hyperactivity in extrinsic laryngeal muscles, restoring normal vocal function.

    Area of Science:

    • Laryngology
    • Neurology
    • Speech-Language Pathology

    Background:

    • Spastic dysphonia is a functional voice disorder characterized by strained, choked phonation.
    • It can involve abnormal activity in intrinsic or extrinsic laryngeal muscles.
    • Adductor type may relate to intrinsic muscles, while other types involve extrinsic muscles.

    Observation:

    • Two patients presented with hyperactive extrinsic laryngeal muscles during phonation.
    • Lidocaine injections into these muscles provided temporary relaxation.
    • Electromyographic (EMG) biofeedback was initiated to monitor and retrain muscle activity.

    Findings:

    • Biofeedback therapy utilizing an EMG monitoring system successfully relaxed hyperactive extrinsic laryngeal muscles.
    • Patients recovered normal vocal abilities through this intervention.

  • This suggests a viable treatment pathway for spastic dysphonia linked to extrinsic muscle hyperactivity.

    • Implications:

    • Extrinsic laryngeal muscle hyperactivity is a treatable cause of spastic dysphonia.
    • EMG biofeedback offers a non-invasive therapeutic option.
    • Further research into laryngeal muscle function in voice disorders is warranted.
