Background: Movement Disorder‐Childhood Rating Scales (MD‐CRS) have been designed in two forms (0–3 and 4–18y) to evaluate various movement disorders in children by Battini et al. The ability of MD‐CRS to capture changes during treatment was tested for both scales with various longitudinal studies and case report studies. Aim: Evaluate psychometric properties of MD‐CRS reliability when used by clinicians without a complete knowledge of this tool. Methods: After brief training in scoring MD‐CRS, three clinicians (a resident doctor, a child neurologist and a physical therapist) independently scored 20 patient videotapes, of children with movement disorders. In addition, the resident doctor scored 40 videos of 20 patients evaluated twice for test‐retest. Reliability was assessed by Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM) and Minimal Detectable Difference (MDD) and was calculated separately for the two forms of the scale and for each score (Index I, Index II and Global Index). Results: for both forms, inter‐rater reliability of Global Index and Index I were good with an ICC ranged between 0.72 and 0.95 and a SEM ranged between 0.04 and 0.06. Instead, results of Index II were substantially moderate for both forms, with an ICC of 0.60 and 0.50, respectively and SEM values were 0.16.. Test‐retest reliability values for all Indexes in both forms showed excellent values with ICCs ranging from 0.95 to 0.99. MDD values were between 0.04 and 0.12. Conclusion: MD‐CRS 0–3 and MD‐CRS 4–18 remain reliable clinical measurement tools for evaluation of MD in developmental age when used by clinicians without a specific knowledge after specialized training.

Abstract
Background: Movement Disorder‐Childhood Rating Scales (MD‐CRS) have been designed in two forms (0–3 and 4–18y) to evaluate various movement disorders in children by Battini et al. The ability of MD‐CRS to capture changes during treatment was tested for both scales with various longitudinal studies and case report studies. Aim: Evaluate psychometric properties of MD‐CRS reliability when used by clinicians without a complete knowledge of this tool. Methods: After brief training in scoring MD‐CRS, three clinicians (a resident doctor, a child neurologist and a physical therapist) independently scored 20 patient videotapes, of children with movement disorders. In addition, the resident doctor scored 40 videos of 20 patients evaluated twice for test‐retest. Reliability was assessed by Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM) and Minimal Detectable Difference (MDD) and was calculated separately for the two forms of the scale and for each score (Index I, Index II and Global Index). Results: for both forms, inter‐rater reliability of Global Index and Index I were good with an ICC ranged between 0.72 and 0.95 and a SEM ranged between 0.04 and 0.06. Instead, results of Index II were substantially moderate for both forms, with an ICC of 0.60 and 0.50, respectively and SEM values were 0.16.. Test‐retest reliability values for all Indexes in both forms showed excellent values with ICCs ranging from 0.95 to 0.99. MDD values were between 0.04 and 0.12. Conclusion: MD‐CRS 0–3 and MD‐CRS 4–18 remain reliable clinical measurement tools for evaluation of MD in developmental age when used by clinicians without a specific knowledge after specialized training.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
