目的检验运动障碍损害量表（DIS）的信度和效度。DIS包括两个分量表：肌张力障碍和舞蹈徐动症。它的措施，这两种现象在运动障碍性脑瘫（CP）。方法25名参与者与运动障碍性脑瘫（17名男性，8名女性，年龄范围5- 22岁，平均年龄13岁6个月，SD 5岁4个月），从特殊学校招募的儿童运动障碍，包括在内。排除标准为前3个月内肌松药的变化、前一年内骨科或神经外科干预以及脊柱融合。评价者间的信度由两个独立的评价者进行验证。对于评定者间的可靠性，评估了组内相关系数。测量的标准误差，最小可检测的差异，和Cronbach的内部一致性的α进行了测定。同时效度的DIS肌张力障碍分量表，Barry-Albright肌张力障碍Scaleadminister.Results的组内相关系数为总DIS评分和两个分量表之间的0.91和0.98之间的评分者间的信度。舞蹈手足徐动症分量表的可靠性高于肌张力障碍分量表。测量的标准误差和最小可检测差值是足够的。Cronbach α值范围为0.89 - 0.93。肌张力障碍分量表与Barry-Albright肌张力障碍量表的Pearson相关系数为0.84（p< 0.001）。未来的研究，对反应的DIS是必要的。
Aim The aim of this study was to examine the reliability and validity of the Dyskinesia Impairment Scale (DIS). The DIS consists of two subscales: dystonia and choreoathetosis. It measures both phenomena in dyskinetic cerebral palsy (CP).METHOD Twenty-five participants with dyskinetic CP (17 males; eight females; age range 5-22y; mean age 13y 6mo; SD 5y 4mo), recruited from special schools for children with motor disorders, were included. Exclusion criteria were changes inmuscle relaxant medication within the previous 3 months, orthopaedic or neurosurgical interventions within the previous year, and spinal fusion. Interrater reliability was verified by two independent raters. For interrater reliability, intraclass correlation coefficients were assessed. Standard error ofmeasurement, theminimal detectable difference, and Cronbach's alpha for internal consistency were determined. For concurrent validity of the DIS dystonia subscale, the Barry-Albright Dystonia Scale was administered.RESULTS The intraclass correlation coefficient for the total DIS score and the two subscales ranged between 0.91 and 0.98 for interrater reliability. The reliability of the choreoathetosis subscale was found to be higher than that of the dystonia subscale. The standard error of the measurement and minimal detectable difference values were adequate. Cronbach's alpha values ranged from0.89 to 0.93. Pearson's correlation between the dystonia subscale and Barry-Albright Dystonia Scale was 0.84 (p< 0.001).INTERPRETATION Good to excellent reliability and validity were found for the DIS. The DIS may be promising for increasing insights into the natural history of dyskinetic CP and evaluating interventions. Future research on the responsiveness of the DIS is warranted.
