Scales in Parkinson's disease.

Area of Science:

• Neurology
• Clinical Assessment
• Health Measurement

Background:

• The Unified Parkinson's Disease Rating Scale (UPDRS), established in 1987, is the primary tool for Parkinson's disease (PD) assessment but requires revision.
• Existing instruments for non-motor PD symptoms often lack specific validation for the disease.
• Quality of life measurements are increasingly vital for a holistic understanding of PD's impact and treatment effectiveness.

Purpose of the Study:

• To evaluate the current state of clinimetric instruments used in Parkinson's disease assessment.
• To discuss the limitations of existing tools and the need for validated measures.
• To explore future perspectives in PD health status assessment, including the application of the WHO's International Classification of Functioning, Disability and Health (ICF).

Main Methods:

• Review of existing literature and instruments for Parkinson's disease assessment.
• Discussion of the validity and applicability of various clinimetric tools.
• Analysis of the role of quality of life and ICF frameworks in PD evaluation.

Main Results:

• The UPDRS is widely used but outdated, necessitating updates.
• Limited validation exists for many instruments measuring non-motor PD symptoms.
• Quality of life and ICF models offer comprehensive approaches to PD assessment.

Conclusions:

• There is a critical need for validated and updated instruments for comprehensive Parkinson's disease assessment.
• Integrating quality of life and ICF frameworks can provide a more holistic view of patient functioning and disability.
• Future research should focus on developing and validating new tools for PD clinimetry.
