A model for selecting alternate foot placement during human locomotion

The selection of alternate foot placement is based on visual inputs and the prediction of future foot placement combined with a set of internal rules that are guided by three determinants: minimum foot displacement, stability, and maintenance of forward progression. These three determinants are weighted differently, depending on different constraints. The first purpose of this review is to define and provide evidence to support this model. Alternate foot placement response latency appears to vary according to methodological and/or task constraints. The paradigms and latency measurement methods...
