To assess the reliability and to evaluate the responsiveness of both the Jebsen-Taylor Test of Hand Function (JTTHF) and the Box and Block Test (BBT) in children with cerebral palsy (CP).
In this retrospective study, the reliability analyses were conducted with paired t-tests considering a short (mean 14d) and a long (mean 120d) time in between two assessment periods. In addition, an intraclass correlation coefficient (ICC) was used to assess the level of congruency. The responsiveness to therapy was conducted with a paired t-test in the whole sample regarding the age, the manual ability level as classified with the Manual Ability Classification System (MACS), and the topography.
Our main results confirmed the tests' reliability in a short time period for the JTTHF in both hands and for the BBT on the less affected hand. These results were consistent with the ICC. The responsiveness was confirmed, except on the less affected hand for the JTTHF, with similar results for age, MACS, and topography approach.
This study supports the use of the JTTHF and the BBT to examine changes after short-term interventions for children with CP. These results should be interpreted with association to normative values or with a control group when used over long assessment periods.
The Box and Block Test (BBT) is reliable in a brief period of assessment in children with cerebral palsy (CP). The Jebsen-Taylor Test of Hand Function (JTTHF) is reliable in a brief period of assessment in children with CP. The JTTHF and BBT are responsive to changes in a brief period of intensive therapy in children with CP. The reliability and responsiveness of the JTTHF and BBT are weak over long assessment periods.
评估 Jebsen-Taylor 手功能测试（JTTHF）和箱块测试（BBT）在脑瘫儿童中的可靠性，并评价其反应度。
在这项回顾性研究中，通过配对 t 检验对短期（平均 14 天）和长期（平均 120 天）两次评估之间的可靠性进行分析。此外，还使用组内相关系数（ICC）评估一致性水平。在整个样本中，根据年龄、手动能力分类系统（MACS）分类的手动能力水平以及病变部位，使用配对 t 检验评估治疗反应。
我们的主要结果证实，在较短的时间内，JTTHF 双手和 BBT 非优势手的测试具有可靠性。这些结果与 ICC 一致。反应性得到了确认，除了 JTTHF 非优势手之外，年龄、MACS 和病变部位方法的结果相似。
这项研究支持在脑瘫儿童进行短期干预后使用 JTTHF 和 BBT 来检查变化。在使用较长评估期时，这些结果应与正常值或对照组关联起来进行解释。
箱块测试（BBT）在脑瘫儿童的短暂评估期内具有可靠性。Jebsen-Taylor 手功能测试（JTTHF）在脑瘫儿童的短暂评估期内具有可靠性。JTTHF 和 BBT 对脑瘫儿童短期强化治疗后的变化具有反应性。在长期评估期内，JTTHF 和 BBT 的可靠性和反应性较弱。
