The relationship between physical growth and a newborn reflex

Splet01. mar. 2015 · Although functional features of stepping at birth such as propulsion and forward translation have not been quantified in detail, infant steps often show “march‐like” characteristics (Thelen, ) with simultaneous and extensive hip and knee flexion and minimal step length (Forssberg, ). SpletWhat Fisher and I (Thelen & Fisher, 1982, 1983) also noted is that in the first two or three months, when stepping disappears, infants have a very rapid weight gain, most of which is subcutaneous fat rather than muscle tissue. Thus, their limbs get heavier but not necessarily stronger.
