Walkers with the frame positioned behind the child have been advocated recently, mainly because they may allow a more upright and therefore more normal ambulation and perhaps encourage favourable neuromuscular development. The purpose of this study was to estimate and compare speed, energy cost, and perceived exertion during walking with an anterior walker and a posterior walker. Ten children with spastic diplegia, average age 11 years, who were familiar with both types of walker participated in the study. Spasticity was measured according to the modified Ashworth scale. Oxygen cost was determined by the argon-diluted method using a mixing box mounted on a backpack, and the perceived exertion was graded. The results of the study showed that there are no differences in the measured variables in walking between the anterior and the posterior walker in children familiar with both walkers and also that most of the children preferred the posterior walker.
最近有人提倡将框架置于儿童身后的助行器，主要是因为它们可能使行走姿势更直立，从而更接近正常行走，或许还能促进良好的神经肌肉发育。本研究的目的是评估和比较使用前置助行器和后置助行器行走时的速度、能量消耗和主观用力程度。十名平均年龄为11岁、熟悉两种助行器的痉挛型双侧瘫儿童参与了该研究。根据改良Ashworth量表测量痉挛程度。使用安装在背包上的混合箱，通过氩稀释法测定氧气消耗，并对主观用力程度进行分级。研究结果表明，对于熟悉两种助行器的儿童，使用前置助行器和后置助行器行走时，所测量的变量没有差异，而且大多数儿童更喜欢后置助行器。
