A study was undertaken, using methods of stabilometry to compare stability of stance in normal children (n = 37) and those with Duchenne muscular dystrophy (n = 61). The purpose of this study was to monitor changes in the locus of the center of gravity and the range and frequency of sway and to evaluate the effect of orthotic application in an attempt to obtain information that would assist further development of orthoses. In group 1, boys with Duchenne muscular dystrophy who were still walking without assistance (mean age 7.2 +/- 1.76 years), the analysis of sway showed that, between 5 and 6 years of age, the boys already had ranges of anteroposterior (A/P) and lateral (Lat) sway that were significantly greater than those found in normal children (A/P P less than 0.05, Lat P less than 0.01). In group 2, boys with Duchenne muscular dystrophy when orthoses had been introduced (n = 23, mean age 10.4 +/- 1.47 years), the center of gravity was returned to a more normal position. There was a reduction of the anteroposterior range of sway, but the lateral range of sway remained significantly greater (P less than 0.01) as did the frequency of sway in both the anteroposterior and lateral directions (A/P P less than 0.001, Lat P less than 0.001).
一项研究采用了姿势稳定测量法，比较正常儿童（n = 37）和杜氏肌营养不良症患儿（n = 61）的站立稳定性。本研究的目的是监测重心位置的变化、摆动范围和频率，并评估矫形器应用的效果，以获取有助于矫形器进一步研发的信息。在第1组中，仍能独立行走的杜氏肌营养不良症男孩（平均年龄7.2 +/- 1.76岁），摆动分析显示，在5至6岁时，这些男孩的前后（A/P）和侧向（Lat）摆动范围已显著大于正常儿童（A/P P < 0.05，Lat P < 0.01）。在第2组中，已使用矫形器的杜氏肌营养不良症男孩（n = 23，平均年龄10.4 +/- 1.47岁），重心恢复到更正常的位置。前后摆动范围减小，但侧向摆动范围仍显著更大（P < 0.01），前后和侧向方向的摆动频率也是如此（A/P P < 0.001，Lat P < 0.001）。
