Psychometric properties mapped in this review.

Property	Maps generated in this review
Known-groups validity	Number and proportion of analyses per DMO and medical condition, which found a statistically significant difference (1) between pathological and healthy gait, or (2) between disease severity strata
Convergent validity	Number and proportion of analyses per DMO and medical condition, which found a statistically significant, cross-sectional association between a DMO and validated measures of relevant constructs (e.g., disease severity, physical function, health-related quality of life, etc.)
Predictive validity	Number and proportion of analyses per DMO and medical condition, which found a statistically significant association between a DMO measured at baseline and a clinically relevant outcome at follow-up (i.e., mortality, physical function, healthcare utilization, etc.)
Responsiveness to intervention	Number and proportion of analyses per DMO and medical condition, which found a significant difference between experimental and control groups in an interventional study
Ecological validity	DMOs measured in clinical and real-world settings were mapped separately and trends were compared qualitatively
