PURPOSE: to check the phonatory function of Parkinson's disease patients before and after therapy with wind instrument emphasizing laryngeal, acoustic, respiratory and vocal intensity modifications. METHODS: this research is a collective and prospective case study. Two subjects were submitted to larynx videoendoscopy, respiratory function valuation, recording of samples voice, vocal intensity measurement and therapy. The acoustic analysis were made through Multidimensional Voice Program advanced. Data analysis were weighed, once that the research is a collective case study. RESULTS: the results showed that respiratory, acoustic and vocal intensity modifications were similar and positive in two subjects. CONCLUSION: the therapy carried through with wind instrument may provide higher efficiency in glottal adduction, movement and respiratory control, providing effective phonation breath use, vocal quality improvement with noise measures decrease, higher phonatory stability and vocal intensity increase.
