Objective: To propose a new voice rehabilitation program for parkinsonian patients based on voice treatment and choral singing (VCST). Design: Pilot test-retest noncontrolled study. Setting: The voice and choral activity, directed by a speech therapist expert in Parkinson’s disease (PD) and choral singing, took place in a quiet room. Participants: 20 consecutive PD patients voluntarily participated in our VCST. All patients had a definite diagnosis of PD according to the clinical criteria of the United Kingdom Parkinson’s Disease Society Brain Bank. Interventions: From October 2003 to February 2004, patients underwent 20 hours of speech therapy, 2 sessions of 1 hour every week, and 26 hours of choral singing, 1 session of 2 hours every week. Main Outcome Measures: Forced vital capacity, forced expiratory volume in 1 second, functional residual capacity (FRC), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP); mean fundamental frequency, jitter percentage, fundamental frequency variation, shimmer percentage, peak amplitude variation, fundamental frequency tremor intensity index, amplitude tremor intensity index, maximum duration of sustained vowel phonation (MDPh); and prosodia reading a passage measured with a visual analog scale, presence of fatigue reading a passage, and prosodia and fatigue during conversational monologue. Results: Using paired t tests, we found a significant improvement of the following variables: percentage FRC (P=.033), MIP (P=.019), MEP (P=.006), MDPh (P=.000), and prosodia reading a passage (P=.046); using Wilcoxon signed-rank tests, we found a significant improvement of fatigue reading a passage (P=.05). No significant difference was found in the other variables taken into consideration. Conclusions: Our VCST for PD patients can improve specific abnormalities with an amusing, agreeable, collective approach. Our results are interesting, but, to find evidence of efficacy, we need to conduct a randomized clinical trial to compare VCST with another voice and speech therapy for PD (ie, the Lee Silverman voice treatment).
