This paper reports the kinematic and kinetic changes in gait with bilateral double rocker sole shoe modifications. Three-dimensional motion analysis techniques were used to evaluate gait characteristics (temporal-spatial, kinematic, and kinetic measures) of forty (40) subjects while wearing baseline and double rocker sole shoes. Walking speed was unchanged by the double rocker modification. Sagittal plane motions showed significant change at the pelvis, hip, knee, and ankle. (p = 0.01). The toe-only rocker consistently resulted in increase in posterior pelvic tilt (p =0.01). Kinetic changes were observed at the hip in the sagittal and transverse planes, and at the knee and ankle in the sagittal planes. Changes in pelvic tilt and hip rotation were hypothesized to result from feelings of imbalance during ambulation with the double rocker sole shoe.
本文报告了双侧双摇椅鞋底改良后步态的运动学和动力学变化。采用三维运动分析技术评估了40名受试者在穿着基线鞋和双摇椅鞋底鞋时的步态特征（时空、运动学和动力学指标）。双摇椅改良并未改变步行速度。矢状面运动在骨盆、髋部、膝部和踝部显示出显著变化（p = 0.01）。仅趾部摇椅始终导致骨盆后倾增加（p = 0.01）。在矢状面和横断面的髋部以及矢状面的膝部和踝部观察到了动力学变化。骨盆倾斜和髋部旋转的变化被推测是由于穿着双摇椅鞋底鞋行走时的不平衡感所致。
