This is a systematic literature review to identify vocal and laryngeal symptoms and associated factors in adult wind instrumentalists. ⋯ The several vocal and laryngeal symptoms found in wind instrumentalists in the selected studies were associated with individual factors (prior vocal alteration, inappropriate vocal habits) and organizational factors (working time, intense use, and instrument type and technique). Although wind instrumentalists' vocal health is recognized in the literature, and vocal and laryngeal symptoms are identified and associated with playing a musical instrument, broadening studies with precise methodologies and analyses is necessary.

Paradoxical vocal fold motion disorder (PVFMD), or induced laryngeal obstruction (ILO), is a clinical phenomenon characterized by inappropriate adduction of the true vocal folds during inspiration. The resultant episodes of acute respiratory distress marked by exercise-induced cough, inspiratory stridor, throat tightness, and shortness of breath are often misattributed to asthma despite normal pulmonary function testing results. Although the pathogenesis of the disease remains unclear, the etiology is likely multifactorial with an inflammatory, neurological, and psychiatric basis. Our trigger reduction approach, consisting of a plant-based, Mediterranean-style diet to treat laryngopharyngeal reflux and sinus toilet, aims to dampen the peripheral neuronal hyperexcitability of the laryngopharyngeal tissues that is hypothesized to contribute to this disorder. The primary objective of the present study was to assess for therapeutic efficacy by analyzing pre- and post-treatment subjective scores using four validated indices: Voice Handicap Index (VHI), Reflux Symptom Index (RSI), Dyspnea Index (DI), and Cough Severity Index (CSI). ⋯ Paradoxical vocal fold motion disorder is a multifactorial disease that poses diagnostic and therapeutic challenges. Early diagnosis and treatment are critical to ensure patient safety, satisfaction, and reduction in health care costs, as mistreatment with asthma pharmacotherapy, intubation, or tracheostomy may exacerbate their dyspnea and lead to preventable hospitalizations. Our results demonstrate that a trigger reduction approach consisting of a plant-based, Mediterranean-style diet and sinus toilet alone may not achieve a clinically meaningful response in the majority of patients. However, given their favorable safety profile, our therapeutic regimen, along with respiratory retraining therapy, may provide symptom relief for selected patients who would otherwise continue to suffer.

Comparative Study
The Effects of Three Physical and Vocal Warm-up Procedures on Acoustic and Perceptual Measures of Choral Sound: Study Replication With Younger Populations.
The purpose of this study was to replicate a previous investigation to assess with two intact children's choirs and a high school choir the potential effects of three choral warm-up procedures (vocal-only, physical-only, physical/vocal combination) on acoustic and perceptual measures of choral sound. ⋯ This study replication indicates similar conclusions as the original investigation with university choruses: a combination choral warm-up that includes both physical and vocal aspects is preferred by singers of all ages, enables more resonant singing, and more in-tune singing. Findings from these investigations provide choral educators with compelling information concerning efficient and effective choral warm-up procedures.

To determine the social and stylistic correlates of vocal fry in a cappella performances. ⋯ Listeners are highly attuned to vocal fry in music but respond to it differently based upon their age, musical training, and the singer's sex. Vocal fry is evaluated more positively among younger, less musically trained listeners, and it is better received in women's voices, suggesting that the use of fry strategically targets a specific audience, i.e., younger and less trained listeners, who interpret fry as a marker of youth and emotional earnestness. These findings show that a single stylistic feature like vocal fry can be imbued with multiple meanings depending on the singer and audience, and its use can serve to include or exclude particular listener groups.
