Original description

Intervention: Intervention group: LSVT treatment: Treatment consists of 4 sessions in 4 consecutive weeks (16 sessions) over a period of one month. The duration of each treatment session is 50-60 minutes and the therapist must have received a certificate of treatment from the LSVT Global Center. Each treatment session consists of two parts. The first part of the daily homework: - The first half of the session (25 minutes) The first task: Maximum stretched movements that are done 15 times to express the vowel / a / with good quality and the highest possible height level. The second task: directional movements, which include 15 times of expressing the vowel / a / with good loudness quality with high pitch and 15 times expressing the vowel / a / with good loudness quality with low pitch. The third task: practical movements, in this section, The patient identifies 10 sentences or phrases that he uses daily (such as good morning), 10 phrases or sentences are repeated 5 times. - The second part of the session (25 minutes) The items worked in the exercises with the same scope and effort, are generalized from daily activities to different and specific speech activities and textures. Sentences or phrases are repeated with a focus on hard work (ie, a list of 20 sentences or phrases that are repeated 10 times). The complexity of the assignments increases over the weeks according to the patient's interests (words> phrases> sentences> reading> conversation). Assignments become more difficult by increasing the length of time (continuity of height for a longer period of time), amplitude (height within normal range), and complexity of tasks (dual processing, background noise, and distractions).. Primary outcome: Perception score of Music emotional bursts (MEB), In the present study, the ability to recognize emotional states of sadness, happiness, fear and neutrality will be done by using the music emotional bursts (MEB) test score. Research has shown that these three emotional states are easier to understand through music. Of course, in this study, only pieces that were played with a violin (including 40 pieces of music), and expressed emotional states of sadness, joy, fear, and neutrality, will be used for evaluation. People listen to the sounds of music and determine which emotional state (out of the 4 emotional states mentioned) they hear. The test score will be calculated as 1 for correct diagnosis and 0 as non-correct diagnosis of emotional state, both in general and separately for emotions (sadness, happiness, fear and neutrality). Timepoint: a day before the intervention, a day after the intervention. Method of measurement: Music emotional bursts test.;Perception Score of Persian affective voices (PAV), in this study, the perception score of non-verbal emotional bursts will be reported based on the score of the Persian version of the Montreal affective voices (MAV). The emotions examined in this test including: anger, disgust, fear, pain, sadness, surprise, happiness, pleasure, and neutrality. The test score will be calculated according to the correct diagnosis and non-correct diagnosis of emotional state (one and zero), both in general and separately for emotions (happiness, sadness, anger, fear, hatred, pain, pleasure, surprise and neutrality). Timepoint: a day before the intervention, a day after the intervention. Method of measurement: Persian affective voices test.;Perception score of speech prosody comprehension(SPC),in this study, the perception score of speech prosody will be taken based on the score of the speech prosody comprehension test(SPC). The emotions examined in this test including: happiness, sadness, anger,fear,disgust, surprise, and neutrality. The test score will be calculated both in general and separately for emotions (happiness, sadness, anger,fear,disgust, surprise, and neutrality). Timepoint: a day before the intervention, a day after the intervention. Method of measurement: speech prosody comprehension test.

Conditions reported: Parkinson disease.
