comparison of The effect of speech therapy , music-therapy and combined speech and music therapy on the vocal characteristics of people with Parkinson's disease by using telerehabilitation

the effect of a combined speech and music therapy on speech function in Parkinson's disease through telerehabilitation. Our hypothesis is that patients in the combined therapy group will have more improvement in the outcome measure than speech therapy group and music therapy group after treatment and 1-month follow-up .

A clinical trial with three groups, with parallel groups, one-way blind, randomized, on 33 patients, used the Rand function of Excel software for randomization.

Individuals selected from Parkinson's patients patients referred to speech therapy clinics, hospitals and clinics in Tehran. The method of study will be explained to them in face to face session . If they were willing to cooperate, The consent form is signed by them and the biography is taken from the people. These people are then evaluated.

idiopathic Parkinson's patients

The present study includes three groups of therapy: speech therapy,music therapy and combined speech and music therapy .The Speech Therapy Group will receive common and routine speech exercises, including breathing exercises, loudness, pitch, and intelligibility. The music exercises will be designed based on the music therapy protocols of previous studies, which consists of five parts: Section 1: Motor exercises; Section 2: Breathing Exercises; Section 3: vocal Exercises; Section 4: Singing Exercises; Section 5: Final Conversation and Homework.The combination therapy group also receives both speech therapy and music therapy at the same time.

voice parameters ( loudness, f0 , The highest and lowest frequency they can produce, jitter and shimmer),

First, using SPSS software for numbers from 1 to 33, we produce three groups with 11 numbers from zero, one or two. By balloting, the speech therapy group was assigned number zero, the combination therapy group number one and the music therapy group number two.To hide the created list, all the mentioned steps are done by someone who does not do the research. Then, each of the groups of zero, one and two are placed inside the closed envelopes and the envelopes are numbered on them so as not to disturb them. After the patients are admitted to the study according to the inclusion and exclusion criteria, the envelopes are opened in order to determine which group each patient will be in.

In this study, the person performing the assessments did not know which group each patient was in. Finally, the data obtained from the study are provided for analysis to a person who is unaware of the therapy groups .
