The maximum phonation time (MPT) is used to assess simple respiratory functions and can be performed anywhere without special instruments. We investigated the association between MPT and respiration, considering the future utilization of simple respiratory assessments during home-based physical therapy.
This cross-sectional study included 140 older adults enrolled in Japanese long-term care insurance (77 men, 63 women; mean age, 77.9±8.0 years). The participants performed the MPT, followed by spirometry. We analyzed the MPT of the three age groups, relative reliability of the MPT values, and the association between MPT and respiratory function.
We found that the MPT of older men requiring long-term care or support was related to age. The intraclass correlation coefficient of MPT was >0.8 for all groups. Only forced vital capacity was associated with MPT in the partial correlation and multiple regression analyses.
MPT could be an alternative assessment of respiratory function in home-based physical therapy for older adults requiring long-term care or support.
最大发声时间（MPT）用于评估简单的呼吸功能，且无需特殊仪器即可在任何地方进行。考虑到未来在家中进行物理治疗时简单呼吸评估的应用，我们研究了MPT与呼吸之间的关联。
这项横断面研究纳入了140名参加日本长期护理保险的老年人（77名男性，63名女性；平均年龄77.9±8.0岁）。参与者先进行MPT测试，然后进行肺活量测定。我们分析了三个年龄组的MPT、MPT值的相对可靠性以及MPT与呼吸功能之间的关联。
我们发现，需要长期护理或支持的老年男性的MPT与年龄有关。所有组的MPT组内相关系数均>0.8。在偏相关和多元回归分析中，只有用力肺活量与MPT相关。
对于需要长期护理或支持的老年人，MPT可作为在家中进行物理治疗时呼吸功能的替代评估方法。
