Movement Disorders - Childhood Rating Scale 4-18 revised in children with dyskinetic cerebral palsy.

BACKGROUND: Movement Disorders - Childhood Rating Scale for age 4-18 (MD-CRS 4-18) is a tool aimed to evaluate movement disorders in developmental age, validated since 2008 and applied in the literature. Psychometric properties, including inter- and intra-reliability and construct validity have been evaluated over time on children and adolescents with different types of movement disorders. AIM: The aim of the study is to revise the Movement Disorders - Childhood Rating Scale 4-18 (MD-CRS 4-18 R) and evaluate its psychometric properties, compared to previous version of the scale, in dyskinetic cerebral palsy. DESIGN: This is a measurement-focused study of video recorder sessions. SETTING: Video session carried out inpatient and outpatient. POPULATION: This measurement-focused study was carried out on a cohort of 57 participants with DCP (37 males; mean age 9 years and 6 months ±3 years and 8 months) evaluated through video-recorded sessions by experienced scorers using MD-CRS 4-18 and MR-CRS 4-18 R. METHODS: Inter-rater reliability, intra-rater reliability of MD-CRS 4-18 and MD-CRS 4-18 R were performed. RESULTS: This study supports the relevant contribution of MD-CRS 4-18 R to identify the severity of movement disorders in dyskinetic cerebral palsy, as indicated by the higher ICC values on Index II compared to previous MD-CRS 4-18 results. Standard Error Measurement (SEM) and Minimally Detectable Difference (MDD) of MD-CRS 4-18 R in DCP were all very low, with SEMs ranging from 0.01 to 0.02 and MDD from 0.03 to 0.06. CONCLUSIONS: Data obtained with MD-CRS 4-18 R are in accordance with previous scale on individuals with movement disorders due to different etiologies, tested with MD-CRS 4-18. CLINICAL REHABILITATION IMPACT: MD-CRS 4-18 R is able to verify natural history of the disease and represents a standardized clinical outcome measure in the evaluation and follow-up of children with DCP. Also MD-CRS 4-18 Revised form is a feasible tool, now easier to understand than the previous one, more available for incoming clinical trials.

Scale for evaluation of movement disorders in the first three years of life.

Most rating scales to assess movement disorders in children were mainly designed for adult patients, and are limited to a single type of disorder. A new scale for developmental age, the Movement Disorder-Childhood Rating Scale, was recently designed and validated for children and adolescents aged 4-18 years. We introduce a new version of this scale, the Movement Disorder-Childhood Rating Scale 0-3, suitable for application in children aged <4 years. The scale was tested for reliability and consistency in 40 children (aged 0.3-3.6 years) with different types of movement disorders. The results indicate high interrater agreement on each item, and a high degree of internal consistency on several proposed items. The scale can be used to assess and monitor young children with movement disorders during specific treatments.

Movement disorder-childhood rating scale: reliability and validity.

A new scale for children and adolescents aged 4-18 years, called the Movement Disorder Childhood Rating Scale, was designed to: (1) describe clinical features of different types of movement disorders; (2) evaluate the intensity of movement disorders in different body regions at rest and during specific tasks; and (3) assess the influence of movement disorders on motor function and daily living activities. The scale is divided into 2 parts: Part I for general assessment, and Part II for movement-disorder severity. It includes a 20-minute standardized video protocol of all items. The scale was applied to 61 patients with different types of movement disorder, and was independently scored by 3 observers. Reliability, construct validity, and consistency indexes are reported. High interrater agreement on each item, and a high degree of internal consistency on several proposed items, were evident.
