Utility of laryngeal electromyography in predicting recovery after vocal fold paralysis1 Michael C Munin, MD, Clark A Rosen, MD, Thomas Zullo, PhD Archives of Physical Medicine and Rehabilitation Volume 84, Issue 8, Pages 1150-1153 (August 2003) DOI: 10.1016/S0003-9993(03)00146-1
Fig 1 Relation between fibrillation potentials and vocal fold motion. By using data from all laryngeal electromyography studies, patients were analyzed based on permanent vocal fold paralysis (VFP) or resolved vocal fold motion. Chi-square analysis showed no significant (NS) relation between fibrillation potentials and vocal fold outcome. No fibrillations (No fibs) indicates that fibrillations were not detected and positive fibrillations (+ Fibs) indicates that fibrillations were observed.

Fig 2 Relation between motor unit recruitment and vocal fold motion. By using data from all laryngeal electromyography studies, patients were analyzed based on permanent vocal fold paralysis or resolved vocal fold motion. Chi-square analysis showed a significant relation between motor unit recruitment and vocal fold outcome (P<.05). Recruitment was dichotomized as absent or greatly decreased (GD) versus normal, slightly decreased (SD), or moderately decreased (MD), as defined in the Methods section.
