We assessed the clinometric characteristics of rating scales used for the evaluation of motor impairment and disability of patients with Parkinson's disease (PD), conducting a systematic review of PD rating scales published from 1960 to the present. Thirty studies describing clinometrics of 11 rating scales used for PD were identified. Outcome measures included validity (including factor structure), reliability (internal consistency, inter‐rater, and intrarater) and responsiveness. We traced… 
Longitudinal metric properties of disability rating scales for Parkinson's disease.
TLDR
The three scales proved adequate for longitudinal assessment of PD disability; UPDRS-ADL was more precise and ISAPD more consistent, and the "minimal clinically important difference" proposed for these scales is: SES, -6; U PDRS- ADL, +2; ISAPD, +1.5 points.
A short scale for the assessment of motor impairments and disabilities in Parkinson’s disease: the SPES/SCOPA
TLDR
The SPES/SCOPA is a short, reliable, and valid scale that can adequately be used in both research and clinical practice.
Global versus factor‐related impression of severity in Parkinson's disease: A new clinimetric index (CISI‐PD)
TLDR
The CISI‐PD is a valid and reliable measure that expands the information obtained via the CGIS and displayed adequate psychometric properties, with satisfactory internal consistency and convergent and known‐groups validity.
Predicting outcomes in Parkinson's disease: comparison of simple motor performance measures and The Unified Parkinson's Disease Rating Scale-III.
TLDR
Four simple, motor performance measures that are easy to administer, objective, quantitative tests that are good indicators of PD progression could offer advantages in both clinical and research settings.
The Unified Parkinson's Disease Rating Scale (UPDRS): Status and recommendations
  • Psychology
    Movement disorders : official journal of the Movement Disorder Society
  • 2003
TLDR
A critique of the Unified Parkinson's Disease Rating Scale (UPDRS) is prepared, recommending that the MDS sponsor the development of a new version of the UPDRS and encourage efforts to establish its clinimetric properties, especially addressing the need to define aMinimal Clinically Relevant Difference and a Minimal Clinical Relevant Incremental Difference.
Psychometric properties of the Unified Parkinson’s Disease Rating Scale and of the Short Parkinson’s Evaluation Scale
TLDR
The results indicate that the SPES is easier and quicker than U PDRS and that it maintains many psychometric properties similar to those of the UPDRS, but with the reduction of a number of items and ordinal levels of each item studied here (producing more homogenous sections than the original versions).
Metric attributes of the unified Parkinson's disease rating scale 3.0 battery: Part II, construct and content validity
TLDR
While the modified H&Y, S&E, and U PDRS displayed satisfactory construct validity, the content validity of all scales except UPDRS Motor Examination failed to attain adequate standards.
Assessment of Parkinson Disease Manifestations
TLDR
The most common rating scales for Parkinson disease are the Unified Parkinson Disease Rating Scale (UPDRS), Hoehn and Yahr staging, and the Schwab and England rating of activities of daily living.
Should gait speed be included in the clinical evaluation of Parkinson’s disease?
TLDR
The findings demonstrate that only a fair to moderate relationship between objectively measured gait speed and physical function as measured subjectively by the clinical rating scale and as evaluated by the patients during self report is found.
The SCOPA-Motor Scale for assessment of Parkinson's disease is a consistent and valid measure.

Evaluation of Parkinson's disease: a new approach to disability.
TLDR
A more extensive employment of disability scales in clinical studies is suggested, which is more accurate in examining in a different way the physical incapacity and handicap of parkinsonian patients in their daily living.
Rating impairment and disability in Parkinson's disease: Evaluation of the unified Parkinson's disease rating scale
TLDR
Assessment of patients with idiopathic Parkinson's disease on the UPDRS and Hoehn and Yahr staging scales shows that the ADL (13 items) and ME (14 items) sections can be reduced to 8 items each without loss of reliability or validity.
Factor structure of the unified Parkinson's disease rating scale: Motor examination section

TLDR
Investigation of the factor structure and internal consistency of the Motor Examination section of the UPDRS in a sample of 294 consecutive patients with idiopathic PD who were assessed while in the “on” state suggests that it provides a useful measure of PD function as well as severity measures of six clinical disability domains.
Scales for rating motor impairment in Parkinson's disease: studies of reliability and convergent validity.
TLDR
The reliability of the ratings assigned to the performance of five sign-and-symptom items drawn from tests of motor impairment in Parkinson's disease was examined, showing that the internal cohesion of the tests was high, especially for the self-care scale.
Evaluation of the Short Parkinson's Evaluation Scale: a new friendly scale for the evaluation of Parkinson's disease in clinical drug trials.
TLDR
A new scale is structured that includes a zero-to three-point scale for each item in the evaluation of PD, and the results obtained strongly favor the introduction of SPES for clinical practice.
Interobserver reliability between neurologists in training of Parkinson's disease rating scales. A multicenter study
TLDR
Analysis of individual item scores within the scales suggests improvements that would offer greater interobserver consistency.
Value and appropriate use of rating scales and apparative measurements in quantification of disability in Parkinson's disease
TLDR
The data confirm the suitability of the investigated scales and give a rational base for their appropriate use in a sense of data reduction and economical evaluation.

TLDR
This study highlights the limitations of clinical rating scales in Parkinson's disease when more than one rater is used and suggests that in designing clinical trials, every effort should be made to ensure that the same patient is always assessed by the same rater.
Evaluation of Parkinson's disease: reliability of three rating scales.
TLDR
Analysis of the various items used has suggested that scales of disability could be a valid alternative to those examined, and reliability using the K index was moderate, although a slight superiority was found with the Columbia University Rating Scale.
Unified Parkinson's disease rating scale characteristics and structure
TLDR
The UPDRS is a multidimensional, reliable, and valid scale, with some inconveniences derived from its internal consistency, discriminant validity, and pragmatic application.
