Objectives
Narrative objectives1
The purpose of this study was to clarify the association between the reliability of CPF measurement for MG patients and respiratory function and comprehensive assessment of MG. if the reliability and validity of CPF measurement for MG patients are clarified, MG symptoms related to respiratory function can be easily understood. If the reliability and validity of CPF measurement in MG patients can be clarified, it will provide a simple way to assess MG symptoms related to respiratory function. This study is clinically meaningful because it will provide a convenient evaluation index that can be performed by patients themselves at the bedside or at home, and it may enable appropriate treatment at the right time even if acute exacerbation of MG symptoms occurs.

Assessment
Primary outcomes
Cough peak flow measurement
Assessment at the time of admission and at the time of discharge
Key secondary outcomes
1) Pulmonary function tests (FVC, FVE1.0, IC, PEFR)
2) MG comprehensive assessment (QMG score, MG composite, MG ADL)
3) Whether or not self expectoration is possible (judged by the necessity of endotracheal suctioning)

Results
The intraclass correlation coefficient was more than 0.95 for pre-and post-treatment. Positive correlations were found between CPF and almost all spirometric values as well as between the differences of pre-and post-treatment in CPF and quantitative myasthenia gravis.
