通过分析自由行走行为的录像记录，对完整的、腿部截肢的以及腿部受限制的一龄竹节虫的步序模式进行了研究。截肢导致了沿身体轴向和横跨身体轴向的前伸运动相对时间的改变。对单个前腿或后腿的限制产生了与截肢动物相似的行走行为，但对中腿的限制导致了前腿和后腿协调性的破坏。由断肢和腿部限制所产生的行为变化被用于检验一个用于生成这些昆虫步序模式的模型的某些假设，并研究本体感受输入的紧张性影响如何被纳入该模型。
The stepping patterns of intact, amputated and leg restrained 1st instar stick insects were examined by analyzing video tape records of their free walking behavior. Amputation produced changes in the relative timing of protraction movements both along and across the body axis. Restraint of individual front or rear legs produced walking behavior similar to that of the amputee animal but restraint of middle legs caused a breakdown in the coordination of front and rear legs. The changes in behavior produced by leg autotomy and restraint were used to test certain assumptions of a model for generating the step pattern of these insects and to investigate how the tonic influence of proprioceptive input might be incorporated into the model.
