Combined SOVT and Respiratory Exercises: Effects on MPT and Respiratory Function
2026年6月28日 更新者：Rukiye Gülcan ANDEROĞLU、Hasan Kalyoncu University
Effects of Combined Semi-Occluded Vocal Tract (SOVT) and Respiratory Exercises on Maximum Phonation Time (MPT) and Respiratory Function in Conservatory Students Across Different Academic Years
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).

详细说明
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.

干预/治疗 |
|---|---|
|
实验性的：SOVT-Breathing Group
The exercises, which included combined sovt and breathing exercises, were performed twice a week for 6 weeks.
The first measurement was taken in the first week, and the final measurement was taken after 6 weeks.
|
The intervention group underwent combined sovt and breathing exercises.
Sovt exercises consisted of phonation exercises using a pipette.
Breathing exercises consisted of pursed-lip breathing, segmental breathing, and diaphragmatic breathing exercises.

无干预：Control Group
The first measurement was taken in the first week, and the final measurement was taken after 6 weeks and no intervention was applied.

研究衡量的是什么？
主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Voice Handicap Index (VHI-10)
大体时间：6 weeks
|
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.

措施说明 |
大体时间 |
|---|---|---|
|
Maximum Phonation Time (MPT)
大体时间：6 weeks
|
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.

Forced Vital Capacity (FVC)
大体时间：6 weeks
|
Forced vital capacity (FVC, L) will be assessed using spirometry according to ATS/ERS recommendations.
Participants will perform at least three acceptable forced expiratory maneuvers, and the highest value in liters will be recorded for analysis.
|
6 weeks
|
|
Forced Expiratory Volume in 1 Second (FEV₁)
大体时间：6 weeks
|
Forced expiratory volume in one second (FEV₁, L) will be assessed using spirometry according to ATS/ERS recommendations.
The highest value obtained from at least three acceptable maneuvers will be used for analysis.
|
6 weeks
|
|
FEV₁/FVC Ratio
大体时间：6 weeks
|
The FEV₁/FVC ratio (%) will be calculated from spirometric measurements obtained according to ATS/ERS recommendations.
The highest acceptable values will be used for analysis.
|
6 weeks
|
|
Peak Expiratory Flow (PEF)
大体时间：6 weeks
|
Peak expiratory flow (PEF, L/min) will be assessed using spirometry according to ATS/ERS recommendations.
The highest value obtained from at least three acceptable maneuvers will be recorded for analysis.
|
6 weeks
