摘要：

背景：对杜氏进行性肌营养不良患儿异常步态的生物力学研究目前尚不多见，且缺乏步态的足底压力特征结果报道。
目的：分析杜氏进行性肌营养不良患儿常速行走的步态运动学及足底压力分布特征。 
方法：利用VICON红外光点捕获系统，采集10名杜氏进行性肌营养不良患儿及10名正常儿童裸足常速行走的三维运动学数据，并利用Medilogic足底压力测试系统记录支撑足的足底压力分布数据。 
结果与结论：杜氏型肌营养不良组行走时的步长明显小于正常对照组，而步宽和重心摇晃幅度则大于正常对照组；杜氏型肌营养不良组步态的双支撑期所占的周期比例大于正常对照组，摆动末期所占的周期比例则小于正常对照组；杜氏型肌营养不良组髋关节最大伸角小于正常对照组，髋关节最大屈角大于正常对照组，摆动相最大膝屈角小于正常对照组，着地时踝关节跖屈角大于正常对照组；杜氏型肌营养不良组在行走过程中最大足底压力小于正常对照组，最大压力的分布向足前区外侧偏移。结果表明，步态周期时间百分比可作为杜氏型肌营养不良患儿行走能力的评价指标，杜氏型肌营养不良患儿在常速行走过程中所表现出的各种非正常的步态特征可能归因于下肢各关节伸肌群力量不足，部分患儿踝关节呈明显的马蹄足内翻也是造成步态异常的重要原因之一。

Abstract:

BACKGROUND: Few studies have been conducted on abnormal gaits in Duchenne muscular dystrophy children, and planar pressure distribution characteristics during walking have not been reported for Duchenne muscular dystrophy children.
OBJECTIVE: To investigate the abnormal gait characteristics in Duchenne muscular dystrophy children.
METHODS: Ten Duchenne muscular dystrophy children and ten age-matched normal children were recruited to participate in this study. The participants performed five trials of walking at self-selected speed, gait kinematics and foot pressure data were collected with VICON motion capture system and Medilogic system simultaneously.
RESULTS AND CONCLUSION: The results showed Duchenne muscular dystrophy children had significantly shorter step length, greater step width and maximum coronal center-of-gravity displacement compared to normal children. Duchenne muscular dystrophy children took longer double support phases and shorter terminal swing phase, and demonstrated less hip maximum extension and greater hip maximum flexion, greater knee flexion in swing phase and great ankle plantar flexion at initial contact compared to normal children. Duchenne muscular dystrophy children had less maximum foot pressure and more anterior and lateral deviation of maximum pressure location. The gait phase proportions were effective on gait assessment for Duchenne muscular dystrophy children. The pathological gait in Duchenne muscular dystrophy children may result from the weakness of extremity extensor and the secondary clubfoot in some Duchenne muscular dystrophy individuals.
