[Purpose] The purpose of this study was to investigate the differences in respiratory function, physical function, and Activities of Daily Living (ADL) between respiratory and non-respiratory patients using community-based home rehabilitation. [Participations and Methods] Maximum Phonation Time (MPT), upper and lower limb muscle strength, and ADL were compared in two groups: a respiratory disease group including respiratory patients and those with respiratory comorbidities, and a non-respiratory disease group. Cutoff values were determined for items that showed significant differences between groups. [Results] There were no significant differences between the two groups in assessments other than MPT. MPT was significantly lower in the respiratory disease group, with an MPT cutoff value of 10.1 sec and an area under the curve of 0.74. [Conclusion] Use of the MPT cutoff value may help to determine whether respiratory function is impaired in patients with respiratory disease.
