Measuring quality of life changes in Parkinson's patients

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

Observational Karadeniz Technical University · NCT06487364

This study is testing how much a 30-session physiotherapy program can improve the quality of life for people with Parkinson's disease by using a questionnaire to track changes.

What this trial studies

This observational study aims to determine the minimal detectable change in the Parkinson's Disease Questionnaire-8 (PDQ-8), which assesses the quality of life in patients with Parkinson's disease. Participants undergoing a 30-session physiotherapy program will report their quality of life changes before and after treatment using the PDQ-8 and Global Rating of Patient-Perceived Changes (GRP-PC) forms. The study will help establish how much improvement in PDQ-8 scores is considered significant for patients.

Who should consider this trial

Good fit: Ideal candidates include Parkinson's patients in stages 1-3 of the Hoehn and Yahr Scale who are receiving regular neurological follow-up and medication.

Not a fit: Patients with secondary neurological diseases, recent surgeries affecting the upper extremities, or significant psychological issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a clearer understanding of meaningful quality of life improvements for Parkinson's patients undergoing rehabilitation.

How similar studies have performed: While similar studies have explored quality of life measures in Parkinson's disease, this specific approach to determining minimal detectable change is relatively novel.
