Outcome Measures

Primary Outcomes (4)

  • Change from baseline forced expiratory volume

    Spirometry

    at baseline and at 24-week postrandomization

  • Change from baseline area between vocal cords

    MRI and CT of larynx

    at baseline and at 24-week postrandomization

  • Change from basiline vocal fold vibration

    Laryngoscopy and stroboscopy

    at baseline and at 24-week postrandomization

  • Evaluate the motor system by recording action potential generated in muscle fibres like thyroarytenoid, lateral cricoarytenoid, posterior cricoarytenoid, interarytenoid, cricothyroid.

    Electromyography

    at baseline
