What is Tonic Neck Reflex?
When we are babies, right after we areborn, we are supposed to react to different stimuli with differentreflex actions. Thus, every baby, if she/he is healthy, should havethese reflexes present, performing them involuntarily. Of course,doctors, as soon as a baby is born, check for the presence of thesereflexes since their absence is not the best scenario, leading tosuspicions that something may be wrong with the infant's brain andnervous system. Tonic neck reflex is one of these crucial reflexeswhich develop with the development of a healthy baby.
Namely, a baby, during the first 6 or 7months of his/her life should react in a specific way when its neck isturned on one side. Once this is done, the baby should have the armon this side stretched while the other hand should bend at the elbow,leaving the rest of the limbs flexed. If this reflex remains presentfor longer than noted above, this could be interpreted as a problemin the infant's development.
