title: Objective and subjective analysis of women's voice with idiopathic Parkinson's disease.
abstract: OBJECTIVE
  To compare the voice quality of women with idiopathic Parkinson's disease and those without it.
  
  
  METHODS
  An evaluation was performed including 19 female patients diagnosed with idiopathic Parkinson's disease, with an average age of 66 years, and 27 women with an average of 67 years-old in the Control Group. The assessment was performed by computed acoustic analysis and perceptual evaluation.
  
  
  RESULTS
  Parkinson's disease patients presented moderate rough and unstable voice quality. The parameters of grade, roughness, and instability had higher scores in Parkinson's disease patients with statistically significant differences. Acoustic measures of Jitter and period perturbation quotient (PPQ) significantly differ between groups.
  
  
  CONCLUSIONS
  Parkinson's disease female individuals showed more vocal alterations compared to the Control Group, when both perceptual and acoustic evaluations were analyzed.
