Factors associated with dysphonia in high school cheerleaders.
Questionnaire responses that encompassed the severity of acute, cheering-related dysphonia, typical vocal use, vocal history, medical history, smoking and drinking behaviors, and A-Scale personality characteristics were obtained from 146 female high school cheerleaders. Multiple-regression analysis was chosen to examine the degree to which the dysphonia severity items could be associated with the remaining items. The results indicated that acute, cheering-related dysphonia may be preceded or accompanied by a compact set of clinical signs that could be incorporated easily into a screening protocol for prospective cheerleaders.
