 The presence of this reflex beyond the newborn stage is also referred to as abnormal extension pattern or extensor tone.The presence of the TLR as well as other primitive reflexes such as the asymmetrical tonic neck reflex (ATNR) beyond the first six months of life may indicate that the child has developmental delays and/or neurological abnormalities.For example, in people with cerebral palsy, the reflexes may persist and even be more pronounced.
