Motor assessment in Parkinson`s disease

Area of Science:

• Neurology
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Parkinson's disease (PD) is a major central nervous system disorder with complex motor symptoms like tremors, rigidity, and gait disturbances.
• Accurate measurement of motor impairment is crucial for tracking PD progression and treatment efficacy, yet remains challenging due to symptom variability and drug effects.
• Existing assessment methods for PD motor function encompass clinimetrics, balance/posture evaluation, upper limb function tests, and gait analysis.

Purpose of the Study:

• To provide a comprehensive overview of the current methodologies for assessing motor function in Parkinson's disease.
• To highlight the diverse range of tools and techniques available for evaluating different aspects of motor impairment in PD patients.
• To inform clinicians and researchers about the latest advancements in motor assessment for Parkinson's disease.

Main Methods:

• Review of existing literature and clinical practices for motor assessment in Parkinson's disease.
• Categorization of assessment methods into clinimetrics, balance and posture assessment, arm and hand function tests, and gait/walking analysis.
• Inclusion of both traditional clinimetric scales and advanced quantitative measurement techniques, such as 3D motion analysis.

Main Results:

• Numerous clinimetric scales (e.g., Hoehn and Yahr, Unified Parkinson's Disease Rating Scale) are widely used for PD progression.
• A variety of tests exist for balance (e.g., Berg Balance Scale, Timed Up and Go) and upper limb function (e.g., Purdue Pegboard, Nine-Hole Peg Test).
• Quantitative gait analysis, particularly 3D movement analysis, represents a recent and popular approach for objective walking assessment.

Conclusions:

• Motor assessment in Parkinson's disease is multifaceted, requiring a combination of approaches to capture the full spectrum of motor deficits.
• The selection of appropriate assessment tools depends on the specific motor domain being evaluated and the clinical context.
• Advancements in quantitative measurement techniques offer more objective and precise evaluations of motor function in Parkinson's disease, improving clinical utility.
