Abstract

Aims

The study was aimed to investigate the difference between boys with Duchenne muscular dystrophy (DMD) and healthy peers in terms of gross and fine motor proficiency, and determine the relationship between motor proficiency and ambulation.

Methods

A total of 24 boys with DMD and 22 healthy peers were evaluated. Demographics and physical characteristics were recorded. The Bruininks Oseretsky Test of Motor Proficiency-Short Form (BOTMP-SF) was administered to evaluate gross and fine motor proficiency in both groups. The 6-minute walk test (6MWT) was performed to evaluate functional walking capacity and North Star Ambulatory Assessment (NSAA) was used to determine ambulatory status of boys with DMD.

Results

The gross motor proficiency score was significantly lower in boys with DMD (p = 0.001). No difference was found between the groups in terms of fine motor proficiency (p = 0.962). The gross motor function of BOTMP-SF was significantly related to 6MWT distance (r = 0.696, p = 0.001) and NSAA (r = 0.738, p = 0.001). No relationship was found between BOTMP-SF fine motor proficiency and 6MWT distance (r = 0.210, p = 0.361), and NSAA (r = –0.020, p = 0.928). There were significant correlations between running speed and agility with 6MWT distance (r = 0.585, p = 0.005) and NSAA (r = 0.650, p = 0.056).

Conclusions

Boys with DMD were more affected in aspects of gross motor proficiency than healthy peers, while fine motor proficiency were found same. The gross motor proficiency was found more related to the level of ambulation.

Duchenne 型肌营养不良症的运动能力和功能性行走与健康同龄人的比较。

摘要

宗旨

该研究旨在调查杜氏肌营养不良症 (DMD) 男孩与健康同龄人在粗大和精细运动能力方面的差异，并确定运动能力与行走能力之间的关系。

方法

共评估了 24 名患有 DMD 的男孩和 22 名健康的同龄人。记录人口统计学和身体特征。Bruininks Oseretsky 运动熟练程度测试 - 简短形式 (BOTMP-SF) 用于评估两组的粗略和精细运动熟练程度。6 分钟步行测试 (6MWT) 用于评估功能步行能力，北极星动态评估 (NSAA) 用于确定 DMD 男孩的动态状态。

结果

患有 DMD 的男孩的粗大运动能力评分显着较低（p  = 0.001）。在精细运动能力方面，两组之间没有发现差异（p  = 0.962）。BOTMP-SF的粗大运动功能与6MWT距离（r  =0.696，p  =0.001）和NSAA（r  =0.738，p  =0.001）显着相关。未发现 BOTMP-SF 精细运动能力与 6MWT 距离（r  = 0.210，p  = 0.361）和 NSAA（r = –0.020 ，p  = 0.928）之间存在关系。跑步速度和敏捷性与6MWT距离之间存在显着相关性（r  = 0.585，p  = 0.005）和 NSAA（r  = 0.650，p  = 0.056）。

结论

与健康同龄人相比，患有 DMD 的男孩在粗大运动能力方面受到的影响更大，而精细运动能力则相同。发现粗大运动能力与行走水平更相关。
