Combined SOVT and Respiratory Exercises: Effects on MPT and Respiratory Function

Hasan Kalyoncu University91 enrolled

Overview

This study aims to investigate the effects of combined SOVT and breathing exercises, administered twice weekly for six weeks to conservatory students, through a randomized controlled trial. The study has two hypotheses: H1: Combined SOVT and breathing exercises increase the maximum phonation duration. H2: Combined SOVT and breathing exercises improve spirometric parameters (FEV₁, FVC, FEV₁/FVC, and PEF).

This study aims to investigate the effects of combined SOVT and breathing exercises, applied twice a week for 6 weeks, on conservatory students at Gaziantep University through a randomized controlled trial. The study has two hypotheses: H1: Combined SOVT and breathing exercises increase maximum phonation duration. H2: Combined SOVT and breathing exercises improve spirometric parameters (FEV₁, FVC, FEV₁/FVC, and PEF). In the intervention group, phonation exercises using a pipette were taught and practiced as part of the SOVT exercise. Simultaneously, pursed-lip breathing, segmental breathing, and diaphragmatic breathing exercises were taught and practiced as breathing exercises. At the end of 6 weeks, the maximum phonation duration of all participants was measured with a stopwatch. Additionally, spirometric parameters were measured using a spirometer.

Outcomes

Primary Outcomes

Voice Handicap Index (VHI-10)

The Voice Handicap Index (VHI) will be used to assess participants' self-perceived voice-related handicap. The questionnaire consists of items evaluating the functional, physical, and emotional impact of voice problems. Total scores range from 0 to 40, with higher scores indicating greater perceived voice handicap.

Time frame: 6 weeks

Secondary Outcomes

Maximum Phonation Time (MPT)

Maximum Phonation Time (MPT) will be assessed by asking participants to sustain the vowel /a/ after a maximal inhalation at a comfortable pitch and loudness. Three trials will be performed with adequate rest between trials, and the longest duration recorded in seconds will be used for analysis.

Time frame: 6 weeks
