Short hamstring muscles can cause several problems for children with cerebral palsy. The results of the clinical measurement of hamstring length are often used in decision-making about treatment of children with cerebral palsy. There are different ways of performing this measurement. The aim of this study was to evaluate the interrater reliability of the unilateral and bilateral measurement of the popliteal angle in children and youth with cerebral palsy.
Two methods for estimating hamstring length using unilateral and bilateral measurements of the popliteal angle were applied in children with cerebral palsy. Both tests were applied bilaterally by two independent examiners on the same day for each child. The intraclass correlation coefficient (ICC) was calculated to evaluate the interrater reliability of both measurements. Seventy young people with cerebral palsy (32 females, 38 males, mean age 10 years 8 months, range 5-22 years) at Gross Motor Function Classification System levels I (n = 17), II (n = 31), III (n = 12) and IV (n = 10) were included.
The interrater reliability was good for both measurements. The ICC values were 0.80 on the right and 0.86 on the left for the unilateral popliteal angle, and 0.82 on the right and 0.83 on the left for the bilateral popliteal angle.
Both unilateral and bilateral measurement of the popliteal angle is a reliable method for estimating hamstring length in children and youth with cerebral palsy.
腘绳肌过短会给脑瘫患儿带来诸多问题。临床测量腘绳肌长度的结果常被用于脑瘫患儿治疗决策。该测量有不同的方法。本研究旨在评估脑瘫儿童和青少年单侧及双侧腘窝角测量的评分者间信度。
对脑瘫患儿应用两种通过单侧和双侧测量腘窝角来估计腘绳肌长度的方法。两位独立检查者在同一天对每个患儿双侧进行这两项测试。计算组内相关系数（ICC）以评估两种测量的评分者间信度。纳入了70名脑瘫青少年（32名女性，38名男性，平均年龄10岁8个月，范围5 - 22岁），其粗大运动功能分类系统水平为I级（n = 17）、II级（n = 31）、III级（n = 12）和IV级（n = 10）。
两种测量的评分者间信度均良好。单侧腘窝角的ICC值右侧为0.80，左侧为0.86；双侧腘窝角的ICC值右侧为0.82，左侧为0.83。
单侧和双侧测量腘窝角都是估计脑瘫儿童和青少年腘绳肌长度的可靠方法。
