RESUMO
BACKGROUND: The focus of this study was to determine if the Voice Handicap Index (VHI) is a valid tool for evaluating an inpatient voice rehabilitation program. PATIENTS AND METHODS: A total of 39 German-speaking patients were asked to complete a German version of the VHI questionnaire at the beginning and 3 months after attending a voice rehabilitation program on an inpatient basis at the Bad Gögging voice center. The data collected were documented and assessed using Microsoft Excel and MATLAB. RESULTS: A significant reduction of the VHI summary score was achieved by 10 of 39 patients. An increased number of voice therapy sessions before the program diminished (!) the VHI score 3 months after the program. Work disability because of the dysphonia before the beginning of the voice rehabilitation program showed no significant correlation with the VHI score. CONCLUSIONS: At present, the VHI cannot be regarded as a reliable measure to evaluate benefit derived from completing a voice rehabilitation program on an inpatient basis. Apparently, numerous prior treatment regimens constitute a negative prognostic criterion for rehabilitation success as measured subjectively by the VHI.
