Document Summary

Adapted to walking: phylogenetic adaptations of lower limbs, trunk and neck are designed to optimize walking, adaptation evidence: Bipedalism: bipedalism: walking on 2 rear limbs (legs, common trait of hominids, thought to have come before the development of the big brain in human evolution, allowed by several evolutionary adaptations. Evolution of hip: hip joints are larger. Ilium is shorter, broader and face laterally: broader ilium helps to abduct. Optimal walking vs. optimal movement control: there are 4 features of walking that help promote the 5 features of optimal movement control, progression (successful, purpose of walking is to progress forward. Control of walking via nervous system: consider nervous system involvement in: Individual muscle activation: sensory feedback from the environment and body, locomotor pattern generation, changes in hr & breathing, coordination, timing, precision of complex muscle activation, avoiding obstacles, safe foot placement, navigating and wayfinding, adjusting speed.
