Graphical Evaluation of Vocal Fold Vibratory Patterns by High-Speed Videolaryngoscopy
Journal of Voice (2014) Vol. 28, No. 1, pp. 106-111

Objective: To characterize the voice and vocal fold function of an individual, it is essential to evaluate vocal fold vibration. The most widely used method for this purpose has been videolaryngoscopy. This article proposes a digital image processing algorithm to ...

Surface-Evoked Laryngeal Sensory Action Potential Evaluation in Neurogenic Chronic Cough
Journal of Voice (2014) Vol. 28, No. 5, pp. 624-630

Neurogenic chronic cough is currently a diagnosis of exclusion. We hypothesized that surface-evoked laryngeal sensory action potential (SELSAP) testing could be used to help establish a diagnosis of laryngeal sensory neuropathy as a cause of chronic cough, based on altered ...

Singing Voice Handicap and Videostrobolaryngoscopy in Healthy Professional Singers
Journal of Voice (2014) Vol. 28, No. 5, pp. 608-613

This study correlates the Singing Voice Handicap Index (SVHI) scores with videostrobolaryngoscopy in healthy professional singers as a measure of self-perceived vocal health versus actual pathology seen on examination. The objective was to measure the strength of self-assessment among professional ...

Detection of Chronic Laryngitis due to Laryngopharyngeal Reflux Using Color and Texture Analysis of Laryngoscopic Images
Journal of Voice (2014) Vol. 28, No. 1, pp. 98-105

Objective: To determine if pattern recognition of hue and textural parameters can be used to identify laryngopharyngeal reflux (LPR). Laryngoscopic images from 20 subjects with LPR and 42 control subjects without LPR were obtained. LPR status was determined using the ...

The Diagnostic Role of High-Speed Vocal Fold Vibratory Imaging
Journal of Voice (2013) Vol. 27, No. 5, pp. 627-631

Although high-speed imaging (HSI) has been identified as a valuable tool in phonatory biomechanics research, to date, there have only been a selected number of reports investigating the clinical utility of HSI. We aim to elucidate the role of HSI ...
