Abstract

IntroductionThe 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. ObjectivesThe 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 MethodsThe 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. ResultsOur 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. ConclusionWe 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.
