Beyond protocol standardization: The importance of data curation and software transparency.

Mancini et al.'s framework for gait assessment in Parkinson's disease (PD) is a valuable contribution, enabling a harmonization of study protocols in this research field and, consequently, a substantial improvement of data interpretation across different cohorts. However, we believe that recommendations concerning data curation and software use should be provided in more detail. To ensure data interoperability and facilitate robust data aggregation from such protocols, appropriate and harmonized data formatting and metadata standards are necessary. We further advocate for the open sharing of gait analysis algorithms, to enhance reproducibility and foster collaborative development.
