It is important to note that while a specific reflex carries out a particular function, the chain reaction of one reflex not inhibiting at the right time can have a very broad and deep impact on the subsequent developmental process. There are hundreds of reflexes identified but the majority of children assessed have one or a cluster of the following.
This reflex is stimulated when sudden and rapid changes are experienced in the visual, auditory or positional sense. Responding like a rudimentary version of an older child's flight/flight response, the Moro reflex should be inhibited when the infant is approximately 4 months old.
Signs of a retained Moro reflex in the older child include:
This grasp reflex is stimulated when a tactile sensation is experienced on the palm of the hands. Responding as a rudimentary version of an older child's pincer grip, the Palmar reflex should be inhibited when the infant is approximately 2 - 3 months old.
Signs of a retained Palmar Reflex in the older child include:
This grasp reflex is stimulated when a slight pressure sensation around the ball of the foot. Responding as a rudimentary receptor for the adult plantar reflex, processing sensory information for the vestibular and balance mechanisms, the Plantar reflex should be inhibited when the infant is approximately 2 - 3 months old.
Signs of a retained Plantar reflex in the older child may include:
The Asymmetrical Tonic Reflex (ATNR) is stimulated as the head turns to one side. Responding in part to aid in the birthing process, the ATNR plays an important role in developing cross lateral, visual processing and co-ordination in the older child. The ATNR should be inhibited when the infant is approximately 6 months old.
Signs of a retained ATNR in the older child may include:
The Tonic Labyrinthine Reflex (TLR) is stimulated as the head moves forward or backwards, above or below the level of the spine. Responding to changes in body position the TLR helps to develop balance, visual and spatial awareness in the older child.
The TLR should be fully inhibited when the infant is approximately 3 and a half years of age.
Signs of a retained TLR in the older child may include:
The Symmetrical Tonic Reflex (STNR) is stimulated as the neck muscles alter during movements of the head forwards and backwards. Responding to changes in the body position across the horizontal plane, the STNR helps to develop co-ordination, muscle tone and postural stability in the older child. The STNR should be inhibited when the infant is approximately 11 months old.
Signs of a retained STNR in the older child may include:
The Spinal Galant Reflex is stimulated when a tactile sensation is applied along the left and right sides of the spine. Responding as a primitive low frequency sound conductor in utero and as an aid to the birthing process, the Spinal Galant Reflex helps to develop postural stability, auditory processing and co-ordination in the older child. Spinal Galant Reflex should be inhibited when the infant is approximately 9 months old.
Signs of a retained STNR in the older child may include:
