Cross-Cultural Adaptation and Validation of the Persian Version of the Children's Voice Handicap Index-10 for Parents.

Objectives: This study aimed to translate and evaluate the psychometric properties of the Children's Voice Handicap Index-10 for Parents (CVHI-10-P) in Persian for assessing voice-related quality of life in Persian-speaking children.

Methods: The CVHI-10-P was translated into Persian and assessed for face and content validity by a panel of speech-language pathologists. The questionnaire was administered to 141 children aged 6-11 years, including 35 with voice disorders and 106 without.

The Immediate Effect of Straw Phonation in Children With Repaired Cleft Palate.

Objective: This study aims to investigate the immediate effect of straw phonation on the phonation of Persian-speaking children with repaired cleft palate.

Study Design: Quasi-experimental preintervention and postintervention.

Methods: Seventeen children with repaired cleft palate and velopharyngeal dysfunction were investigated.

Effectiveness of Oral-Motor Stimulation on Oral Feeding in Premature Infants: A Protocol for Systematic Review and Meta-Analysis of Controlled Randomized Trials.

Objectives: Premature infants (born before 37 weeks of gestational age) frequently experience feeding difficulties due to underdeveloped oral motor skills and poor chewing, swallowing, and breathing coordination. In order to improve oral feeding efficiency in these infants, Oral-Motor Stimulation (OMS) has been used in various studies. This systematic review study will aim to assess the effectiveness of OMS for oral feeding in preterm infants.

The Vocal Hygiene Treatment Programs for Singers: A Systematic Review.

Objectives: This systematic review aims to explore the effectiveness of voice health education interventions among singers, particularly focusing on vocal hygiene treatment programs tailored for professional voice users.

Study Design: Systematic review.

Methods: Preferred Reporting Items on Systematic Reviews and Meta-Analysis guidelines were followed to conduct this systematic review.

The quantitative ultrasound study of tongue shape and movement in normal Persian speaking children.

Objectives: Ultrasound research on speech production in normal speakers has long used quantitative measurements in different languages. However, no studies in this area have been conducted in the Persian language. This study investigated Persian speaking children scores on two single curve measures of tongue shape, based on midsagittal tongue shape data from ultrasound imaging.

Validity and Reliability of the Persian Version of the Dysphagia Handicap Index (DHI).

Introduction: The Dysphagia Handicap Index (DHI) is one of the instruments used for measuring a dysphagic patient's self-assessment. In some ways, it reflects the patient's quality of life. Although it has been recognized and widely applied in English speaking populations, it has not been used in its present forms in Persian speaking countries.

Temporal characteristics of nasalization in Persian speaker children with and without cleft palate.

Objectives: The purpose of this study was to measure and compare temporal patterns of nasalization in Persian children with and without cleft palate in three vowel contexts.

Methods: A Sample of 14 children with repaired cleft palates with or without cleft lip with moderate to severe hyper nasality and 14 children without cleft palate was chosen as subjects. The subjects were chosen from the ages of 4 to 12 years.

Assessment of hypernasality for children with cleft palate based on cepstrum analysis.

Hypernasality is a frequently occurring resonance disorder in children with cleft palate. In general, an operation is necessary to reduce the hypernasality and therefore an assessment of hypernasality is imperative to quantify the effect of the surgery and design the speech therapy sessions, which are crucial after surgery. In this paper, a new quantitative method is proposed to estimate hypernasality.
