Walking ability in Duchenne Muscular Dystrophy (DMD) deteriorates progressively until complete loss of the function. Interventions aimed at maintaining ambulatory ability relies on accurate clinical-based scores and evaluations of walking. This kind of assessment has intrinsic limitations. A 3D optoelectronic system could provide elements useful for the functional evaluation of patients with DMD. Nineteen boys with DMD were evaluated using the 6-Minutes Walking Test, North Star Ambulatory Assessment and 3D gait analysis. Participants' gait parameters were compared to those of an age-matched control group and correlated with standard clinical scores. Seventeen kinematic variables differed between DMD and control groups. Strong correlations with North Star Ambulatory Assessment were found for stride width, gait velocity and ankle angles on the sagittal plane. The 6-Minutes Walking test did not correlate with investigated kinematic variables but showed a correlation with North Star Ambulatory Assessment. Our data support the reported DMD gait pattern characterized by increased anterior pelvic tilt and ankle plantar flexion. The stride width and ankle kinematics emerged as the main representative gait parameters of DMD global ambulatory status. Although preliminary, our findings suggest that 3D gait analysis may provide useful objective and accurate parameters reflecting the functional ability of individuals with DMD.

Duchenne 型肌营养不良症的步态评估:3D 步态分析与临床评估的关系

杜氏肌营养不良症 (DMD) 的行走能力逐渐恶化,直至完全丧失功能。旨在维持行走能力的干预措施依赖于准确的临床评分和步行评估。这种评估具有内在的局限性。3D 光电系统可以为 DMD 患者的功能评估提供有用的元素。使用 6 分钟步行测试、北极星动态评估和 3D 步态分析对 19 名患有 DMD 的男孩进行了评估。参与者的步态参数与年龄匹配的对照组进行比较,并与标准临床评分相关。DMD 组和对照组之间有 17 个运动学变量不同。发现步幅与北极星动态评估有很强的相关性,矢状面上的步态速度和踝关节角度。6 分钟步行测试与研究的运动学变量不相关,但显示与北极星动态评估相关。我们的数据支持报告的 DMD 步态模式,其特征是骨盆前倾和踝关节跖屈增加。步幅宽度和脚踝运动学成为 DMD 全球动态状态的主要代表性步态参数。虽然是初步的,但我们的研究结果表明 3D 步态分析可能提供有用的客观和准确的参数,反映 DMD 患者的功能能力。我们的数据支持报告的 DMD 步态模式,其特征是骨盆前倾和踝关节跖屈增加。步幅宽度和脚踝运动学成为 DMD 全球动态状态的主要代表性步态参数。虽然是初步的,但我们的研究结果表明 3D 步态分析可能提供有用的客观和准确的参数,反映 DMD 患者的功能能力。我们的数据支持报告的 DMD 步态模式,其特征是骨盆前倾和踝关节跖屈增加。步幅宽度和脚踝运动学成为 DMD 全球动态状态的主要代表性步态参数。虽然是初步的,但我们的研究结果表明 3D 步态分析可能提供有用的客观和准确的参数,反映 DMD 患者的功能能力。
