A framework to standardize gait study protocols in Parkinson's disease.

Area of Science:

• Neurology
• Biomedical Engineering
• Clinical Trials

Background:

• Gait outcomes are highly sensitive for Parkinson's disease (PD) diagnosis, intervention effects, and progression monitoring.
• Lack of standardized protocols and gait measures hinders data aggregation and limits clinical trial adoption.
• Heterogeneity in results impedes the reliable use of gait analysis in research.

Purpose of the Study:

• To establish recommendations for a minimum set of gait measures for Parkinson's disease research.
• To enhance standardization across studies evaluating individuals with PD.
• To facilitate data aggregation and improve the consistency of gait outcome reporting.

Main Methods:

• The Gait Advisors Leading Outcomes for Parkinson's (GALOP) committee developed recommendations.
• A five-step approach informed by expert consensus on best practices was employed.
• Recommendations focus on standardizing protocols for quantitative gait measures.

Main Results:

• A minimum set of meta-data for gait protocols is recommended.
• A standardized minimum gait assessment protocol at a comfortable speed is proposed.
• Suggestions for challenging gait testing scenarios are included.

Conclusions:

• Standardized gait protocols and outcomes can accelerate PD research and clinical trials.
• Harmonizing protocols across sites will foster collaboration and improve data reliability.
• Open data sharing and standardized methods aim to enhance patient care and quality of life for individuals with PD.
