在跑步机上和地上条件下的步态分析用于研究神经元组织和运动的个体发育的科学方法以及各种临床应用。我们调查了12名成人和14名儿童（6-7岁）在地上和跑步机运动（相同的步态速度）之间的差异。在跑步机运动的步频增加了7%，在成人和10%的儿童相比，地上行走，而步长和站立阶段的步行周期减少。然而，摇摆阶段在成人中显著增加了5%，在儿童中保持不变。平衡相关的步态参数，如步宽和脚旋转角度增加在跑步机运动。在大多数受试者中，在跑步机行走10分钟后，步长的减少被发现是稳定的。关于在跑步机条件下的步行周期的移位阶段和改变的平衡相关步态参数，我们假设在跑步机步行中的中央模式发生器的不同调制，由于改变的传入输入。关于地上和跑步机行走的儿童之间的显着差异，它讨论了系统是否产生和整合不同的运动调制成一个稳定的运动模式已达到满负荷在6-7岁的儿童。(C)1997 Elsevier Science爱尔兰有限公司
Gait analysis on the treadmill and in the overground condition is used both in scientific approaches for investigating the neuronal organisation and ontogenetic development of locomotion and in a variety of clinical applications. We investigated the differences between overground and treadmill locomotion (at identical gait velocity) in 12 adults and 14 children (6-7 years old). During treadmill locomotion the step frequency increased by 7% in adults and 10% in children compared to overground walking, whereas the stride length and the stance phase of the walking cycle decreased. The swing phase, however, increased significantly by 5% in adults and remained unchanged in children. Balance-related gait parameters such as the step width and foot rotation angles increased during treadmill locomotion. The reduction of the step length was found to be stable after 10 min of treadmill walking in most subjects. With regard to the shifted phases of the walking cycle and the changed balance related gait parameters in the treadmill condition, we assume a different modulation of the central pattern generator in treadmill walking, due to a changed afferent input. Regarding the pronounced differences between overground and treadmill walking in children, it is discussed whether the systems generating and integrating different modulations of locomotion into a stable movement pattern have reached full capacity in 6-7 year old children.
