Maximal Inspiratory Pressure, Maximal Expiratory Pressure, and Maximum Phonation Time in Singers, Untrained Normal Person, and Patients with Vocal Cord Diseases

ABSTRACT

MIP was significantly increased in singers, compared to the untrained group. MIP in patients showed decreasing tendency compared to the untrained group, but were significantly lower than that in singers. MEP in singers was higher than that in the untrained group. MPT increased significantly in singers, but diminished in patients compared to the untrained group. MIP, MEP, and MPT in male singers were 50.8%, 61.0%, and 28.7 % higher than those in female singers. MIP, MEP, and MPT in the untrained male were more increased 32.3%, 25.0%, and 28.7%, respectively than those in the untrained female. There was no correlation between MPT and MIP or MEP. Regression analysis of the data set showed that weight and vocal cord dysfunction was a positive predictor of MPT. Factors affecting MIP were male, singers and weight. Factors affecting MEP were male, singers, vocal cord dysfunction and weight.
