Abstract

<p>[Purpose] The purpose of this study was to examine the concurrent validity of the ventilation function measured by a spirometer, the Maximum Phonation Time (MPT), and the Maximum Expiratory Time. [Participants and Methods] The subjects were 23 healthy persons who did not have any respiratory-related abnormalities. The subjects were examined for basic attributes, the ventilation function test with a spirometer, MPT, and Maximum Expiratory Time. The relationships between MPT and Maximum Expiratory Time and each evaluation item were investigated. [Results] There were significant positive correlations between MPT and Maximum Expiratory Time, vital capacity, and %vital capacity. Maximum Expiratory Time did not correlate with any spirometer respiratory function test. [Conclusion] MPT may be a simple method for measuring vital capacity.</p>
