Determination of the Minimal Detectable Change of the Parkinson's Disease Questionnaire-8

Determination of the Minimal Detectable Change and Minimum Clinically Important Change Score of the Parkinson's Disease Questionnaire-8

This study is conducted to determine how many units of improvement the Parkinson's Disease Questionnaire-8 (PDQ-8), used to evaluate the quality of life of Parkinson's patients, should have to express a significant change in the quality of life. Patients for whom a 30-session physiotherapy program is recommended will be included in the study. Patients will be asked to express the change in their quality of life at the end of treatment. The PDQ-8 survey and Global Rating of Patient-Perceived Changes (GRP-PC) forms will be used to determine these changes. Evaluations will be repeated at the beginning of the treatment program and at the end of the 30th session.
