PURPOSE We aimed at verifying an association between voice disorders/stress and loss of work ability among female teachers who work in São Paulo's public school system. METHODS This is a paired case- control study. The case group was composed offiteachers with alterations in speech and larynges assessments, and the control group was formed by teachers without alterations in these evaluations ...

OBJECTIVE To evaluate the effectiveness of interventions for treating functional dysphonia or preventing voice disorders in adults. DATA SOURCES We searched MEDLINE (1950 to 2006), EMBASE (1974 to 2006), CENTRAL (Issue 2 2006), CINAHL (1983 to 2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006), and the Occupational Health databases OSH-ROM (February 2006).

OBJECTIVES To elucidate the phenotypes and pathophysiology of speech and voice disorders in Parkinson's disease (PD) with subthalamic nucleus deep brain stimulation (STN-DBS). METHODS We conducted a cross-sectional study on 76 PD patients treated with bilateral STN-DBS (PD-DBS) and 33 medically treated PD patients (PD-Med). Speech and voice functions, electrode positions, motor function and c...

Purpose The vocal auditory-motor control of individuals with hyperfunctional voice disorders was examined using a sensorimotor adaptation paradigm. Method Nine individuals with hyperfunctional voice disorders and 9 individuals with typical voices produced sustained vowels over 160 trials in 2 separate conditions: (a) while experiencing gradual upward perturbations in the fundamental frequency...

The sample of this research were seven children with neuro-motoric disorders (of both sexes3 girls and 4 boys). Acoustic analysis of voice parameters, representing variables in this research (fundamental frequency, jitter, shimmer, harmonic to noise ratio as well as maximum duration of the vowel /a/) has been made by using EZ Voice Plus program for voice analysis. The results of correlation mat...

Background: To investigate the value of standard deviation fundamental frequency (F0 SD), jitter, and shimmer for evaluation voice quality description vocal characteristics in patients with disorders.
