TABLE 1.
Characteristics and classification of the most cited measurement tools.
| Instrument | Types of assessment | Type of ADL | Developed for use in PD | Scale has been applied to PD populations | Used by other groups beyond the original developing group | Clinimetric properties studied for PD population | Recommendation level |
| MDS-UPDRS | ClinRO | Basic and instrumental ADL | Yes | Yes | Yes | Internal consistency, concurrent validity, face validity. Correlation of Part II with disability measures and quality of life scales. |
Recommended |
| S&E ADL | ClinRO | PRO | Not specify | Yes | Yes | Yes | Test-retest reliability, inter-rater/intra-rater reliability, minimal detectable changes, and minimal clinical important difference | Recommended |
| Barthel ADL | ClinRO | PRO | Basic ADL | No | Yes | Yes | Test-retest reliability, inter-rater/intra-rater reliability, internal consistency, convergent validity | Suggested |
| Lawton-Brody | ClinRO | PRO | Instrumental ADL | No | Yes | Yes | No | Listed |
| FIM | ClinRO | ObsRO | Basic ADL | No | Yes | Yes | No | Listed |
| ADCS-ADL | ClinRO | Basic and instrumental ADL | No | Yes | Yes | No | Listed |
| UPDRS | ClinRO | Basic and instrumental ADL | Yes | Yes | Yes | Test–retest reliability (all and ADL section), inter-rater reliability, internal consistency, criterion and convergent validity. Regarding Part II, floor and ceiling effects, convergent validity, reliability, and standard error of measurement were found to be adequate. |
Recommended, but replaced by the MDS-UPDRS |
