Abstract：
OBJECTIVE: To determine if estimates of functional muscle strength from a novel progressive lateral-step-up test (LSUT) are feasible, reliable, and related to physical activity in children with cerebral palsy (CP).
METHODS: Cross-sectional; test-retest reliability Subjects/Patients: Children with CP and typically developing control children (n = 45/group).
METHODS: An LSUT with 10, 15, and 20 cm step heights was completed. It was repeated 4 weeks later in 20 children with CP. A composite score of LSUT was calculated based on the step height and number of repetitions completed. Physical activity was assessed using monitors worn on the ankle and hip.
RESULTS: Only 4 (13%) of the children with CP were unable to complete a lateral step-up repetition without assistance. All children were able to complete at least 1 repetition with assistance, though more than twice as many children with CP required assistance at 15 and 20 cm step heights than at the 10 cm step height (p < 0.01). Children with CP had 59 to 63% lower LSUT performance, 37% lower physical activity assessed at the ankle, and 22% lower physical activity assessed at the hip than controls (all p < 0.01). The intra-class correlation coefficient ranged from 0.91 to 0.96 for LSUT performance at the different step heights and was 0.97 for the composite score. All LSUT performance measures were positively related to ankle physical activity in children with CP (r range = 0.43 to 0.47, all p < 0.01). Only performance at 20 cm and the composite score were positively related to hip physical activity (r = 0.33 and 0.31, respectively, both p < 0.05). The relationship between the LSUT performance and physical activity at both the ankle and hip increased when age and sex were statistically controlled (model r range = 0.55 to 0.60, all p < 0.001).
CONCLUSIONS: Estimates of functional muscle strength from a novel progressive LSUT are feasible, reliable, and positively related to physical activity in children with CP.

摘要：
目的：为了确定从一种新型的渐进式外侧步升试验（LSUT）估计功能肌肉力量是否可行，可靠,与脑瘫（CP）儿童的体育锻炼有关。
方法：横断面；重测信度受试者/患者：患有CP的儿童和通常发展中的对照儿童（n=45/组）。
方法：完成了具有10、15和20cm台阶高度的LSUT。4周后，在20名CP儿童中重复了这种情况。基于台阶高度和完成的重复次数计算LSUT的综合得分。使用戴在脚踝和臀部的监视器评估身体活动。
结果：只有4名（13%）CP患儿在没有帮助的情况下无法完成横向递升重复。所有儿童都能在协助下完成至少1次重复，尽管在15和20厘米的步高比10厘米的步高需要帮助的CP儿童多两倍（p<0.01）。CP儿童的LSUT表现降低了59％至63％，脚踝评估的体力活动降低37%，髋关节的体力活动比对照组低22％（所有p<0.01）。对于不同台阶高度的LSUT表现，类别内相关系数为0.91至0.96，而对于综合评分为0.97。所有LSUT表现指标均与CP患儿的踝关节体力活动呈正相关（r范围=0.43至0.47，均p<0.01）。仅20cm处的表现和综合评分与髋关节体力活动呈正相关（r分别为0.33和0.31，两者p<0.05)。当年龄和性别得到统计学控制时，踝关节和髋关节的LSUT表现与体力活动之间的关系增加（模型r范围=0.55至0.60，所有p<0.001）。
结论：从一种新型的渐进性LSUT评估功能性肌肉力量是可行的，可靠,与CP患儿的体力活动呈正相关。
