Gait on slippery floors.

You seem to see a glossy wetness to the tile floor ahead of you in the supermarket. Is that just a really polished floor or is that water? Hey, it might be slippery, lets make some adaptive changes up there in the brain.
Postural and temporal gait adaptations, which affected ground reaction forces occur.
This study found that “statistically significant gait adaptations included reductions in stance duration (SD) and loading speed on the supporting foot, shorter normalized stride length (NSL), reduced foot-ramp angle and slower angular foot velocity at heel contact. As a result of these adaptations, anticipation of slippery surfaces led to significant changes in lower extremity joint moments, a reflection of overall muscle reactions.”
Significant gait changes occur when there is percieved risk of slipping, and in this study, “even though subjects were asked to walk as naturally as possible”.
