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
Study Arms (4)
functional findings
