To further investigate the construct of Manual Ability Classification System (MACS) by evaluating the relationship between children's designated MACS levels and their outcomes on two different tests of hand function, measuring capacity and performance, respectively. Another aim was to use the International Classification of Functioning, Disability and Health-Child and Youth version (ICF-CY) as a framework to explore the uniqueness of the assessments.
Ninety-one children with cerebral palsy in MACS levels I-V, aged 5-17 years (mean 9.8, SD 3.0) participated. Data were collected using MACS, ABILHAND-Kids and Box and Block Test.
A strong association between MACS and ABILHAND-Kids (rs = -0.88, p < 0.05) and MACS and Box and Block Test (rs = -0.81, p < 0.05) was demonstrated. Children's performance differed significantly between the different MACS levels (ABILHAND-Kids F (4:86) = 103.86, p < 0.001, Box and Block Test F (4:86) = 59.18, p < 0.001). The content comparison with ICF-CY, as a frame of reference, showed that these instruments capture fine hand use in the activity and participation component. The linking of the instruments to various ICF-CY categories demonstrated conceptual differences between the instruments. MACS had the broadest representation of ICF-CY domains.
This study strengthens the construct, and thereby the validity, of MACS as a classification of children's hand function, expressed by the handling of objects in everyday activities in their daily environments.
• This study has strengthened the evidence of Manual Ability Classification System (MACS) as being a valid and useful classification of children's hand function. • The various MACS levels describe different degrees of hand-function impairment. • MACS give a broad description of children's manual ability in a variety of daily life domains.
通过评估儿童指定的 MACS 水平与两种不同手部功能测试结果之间的关系，进一步研究手动能力分类系统（MACS）的结构，这两种测试分别测量能力和表现。另一个目的是使用国际功能、残疾和健康分类-儿童和青少年版（ICF-CY）作为框架，探索评估的独特性。
91 名 MACS 水平 I-V 的脑瘫儿童（年龄 5-17 岁，平均 9.8 岁，标准差 3.0 岁）参与了该研究。使用 MACS、ABILHAND-Kids 和方块和木块测试收集数据。
MACS 与 ABILHAND-Kids（rs=-0.88，p<0.05）和 MACS 与方块和木块测试（rs=-0.81，p<0.05）之间存在很强的关联。儿童在不同 MACS 水平之间的表现差异显著（ABILHAND-Kids F（4:86）=103.86，p<0.001，方块和木块测试 F（4:86）=59.18，p<0.001）。与 ICF-CY 进行内容比较，作为参考框架，表明这些工具在活动和参与成分中捕捉到精细的手部使用。将这些工具与各种 ICF-CY 类别联系起来，表明了这些工具之间存在概念差异。MACS 对 ICF-CY 领域的代表性最广泛。
本研究加强了 MACS 作为儿童手部功能分类的结构，即通过日常环境中日常活动中的物体处理来表达，从而提高了其有效性。
本研究加强了手动能力分类系统（MACS）作为儿童手部功能分类的有效性和实用性的证据。
不同的 MACS 水平描述了不同程度的手部功能障碍。
MACS 广泛描述了儿童在各种日常生活领域的手动能力。
