Abstract

Introduction: The Myasthenia Gravis-Activities of Daily Living scale (MG-ADL) is a short, and easy to use disease-specific quality of life during daily routine tool in myasthenia gravis.

Objectives: The purpose of our work was to evaluate neurological condition patients with myasthenia gravis using the form MG-ADL in order to enable the introduction in common use of an instrument which allows for the assessment of patients with myasthenia gravis.

Patients and methods: The total number of 50 patients with MG were qualified for the examination. Each patient underwent neurological examination and completed the quality of life evaluation questionnaire MQ-ADL. Additionally, each patient was asked to evaluate the quality of his/her life by means of questionnaire MG-QOL 15 and MG Composite in Polish language version.

Results: Our analysis showed a positive correlation with other scales used - MG-QOL 15, MGFA, MG Composite. The intensification of neurological symptoms showed significant relation with obtained higher number of points in MG-ADL questionnaire. The MG-ADL was found to have high internal consistency, test-retest reliability, and concurrent validity.

Conclusion: We confirmed reliability and dependability of the questionnaire in the the test-retest assessment. The MG-ADL is accepted to be a reliable and valuable tool for measuring disease-specific QOL in Polish patients with MG.
