Cross sectional area measurement of tendon and ligament in vitro: a simple, rapid, non-destructive technique.

abstract：:Walking appears to be passively unstable in the lateral direction, requiring active feedback control for stability. The central nervous system may control stability by adjusting medio-lateral foot placement, but potentially with a metabolic cost. This cost increases with narrow steps and may affect the preferred step ...
