The biomechanics of lower limb locomotion is a yet unknown mixture of neurological control and physical parameters. The current study explored attaching a rehabilitative anklebot to subjects walking on a treadmill and observed duration, kinematic, and electromyography data to determine the biomechanical response to the asymmetric loading. The present report identified various gait cycle parameters that changed as a response to the asymmetric loading. Notably, significant differences in the stride time of the legs occurred under loading, while contralateral stride times also adjusted to remain equal to those of the loaded legs. Symmetry index analysis led to the conclusion that, while the asymmetric loading of the lower limbs had some effects on temporal gait parameters, the body adjusted to minimize any temporal asymmetry. However, goniometer data demonstrated kinematic changes in response to loading as knee flexion peaked earlier in the gait cycle.

<Abstract>The biomechanics of lower limb locomotion is a yet unknown mixture of neurological control and physical parameters. The current study explored attaching a rehabilitative anklebot to subjects walking on a treadmill and observed duration, kinematic, and electromyography data to determine the biomechanical response to the asymmetric loading. The present report identified various gait cycle parameters that changed as a response to the asymmetric loading. Notably, significant differences in the stride time of the legs occurred under loading, while contralateral stride times also adjusted to remain equal to those of the loaded legs. Symmetry index analysis led to the conclusion that, while the asymmetric loading of the lower limbs had some effects on temporal gait parameters, the body adjusted to minimize any temporal asymmetry.
