Abstract

Background

Duchenne muscular dystrophy (DMD) is one of the most common and disabling childhood genetic diseases. The course of DMD involves progressive muscular degeneration and weakness, leading to functional decline. The Performance of the Upper Limb scale (PUL) is a specific instrument designed to assess the upper limb function of patients with DMD.

Objective

To adapt the PUL cross-culturally to Brazilian Portuguese (PUL-Br) and assess the convergent validity, structural validity, inter-rater reliability, and internal consistency for Brazilian patients with DMD

Methods

The cross-cultural adaptation involved six steps: translation to Brazilian Portuguese, Brazilian Portuguese translation synthesis, back-translation to English, back-translation synthesis, an expert committee review, and a pre-final version test (n = 12). The convergent validity of the PUL-Br was evaluated by examining its correlation to the Motor Function Measure scale (MFM) using 30 patients with DMD. Confirmatory factor analysis was conducted to assess structural validity. Intraclass correlation coefficient (ICC) verified the PUL-Br interrater reliability. Cronbach's alpha was calculated to verify internal consistency.

Results

The PUL was cross-culturally adapted to Brazilian Portuguese. A strong and positive correlation was found between the PUL-Br total score and the total score on the MFM (r = 0.83; 95% CI: 0.67, 0.91). The PUL-Br showed a satisfactory fit of the data to the three-factor model, excellent inter-rater reliability (ICC: 0.94), and good internal consistency (Cronbach's: 0.91).

Conclusion

The PUL-Br is valid and reliable for assessing the upper limb function of Brazilian patients with DMD.

为患有杜兴氏肌肉萎缩症的儿童和青少年编制巴西版上肢表现量表

背景杜氏肌营养不良症（DMD）是最常见的致残性儿童遗传病之一。DMD 的病程包括进行性肌肉退化和无力，从而导致功能衰退。上肢功能量表（PUL）是一种专门用于评估 DMD 患者上肢功能的工具。目标将 PUL 跨文化改编为巴西葡萄牙语（PUL-Br），并评估其对巴西 DM 患者的收敛效度、结构效度、评分者间信度和内部一致性方法跨文化改编包括六个步骤：翻译成巴西葡萄牙语、巴西葡萄牙语翻译合成、反译成英语、反译合成、专家委员会审查和最终版本前测试（n = 12）。通过对 30 名 DMD 患者进行运动功能测量量表 (MFM) 与 PUL-Br 的相关性研究，评估了 PUL-Br 的收敛有效性。为评估结构有效性，还进行了确认性因子分析。类内相关系数 (ICC) 验证了 PUL-Br 的施测者间可靠性。计算了 Cronbach's alpha 以验证内部一致性。PUL-Br总分与MFM总分之间存在很强的正相关（r = 0.83; 95% CI: 0.67, 0.91）。PUL-Br 的数据与三因素模型的拟合度令人满意，评分者之间的可靠性极佳（ICC：0.94），内部一致性良好（Cronbach's：0.91）。
