What is NMI?

Neuromotor Immaturity is a cluster of subtle signs indicating the relative maturity of the Central Nervous System plus the below optimal functioning of:

  • the vestibular system (gives us balance and information about our position in space)
  • the proprioceptive system (nerves that give an inner sense of the location and position of the body)
  • patterns of muscular control which give our posture

People with Neuromotor Immaturity can experience difficulties with related skills such as balance, coordination, and visual perception.  These can affect behaviour and educational performance in children.  They manifest as chronic anxiety and emotional sensibility in adults.


Children are remarkable adaptable, and children’s brains doubly so.   Children with NMI often find a way to get round any immaturity, for instance by using their brain’s higher cognitive functions.   NMI may only appear as a sense that a child is not ‘doing as well as they should’ at particular tasks, given their other abilities, or that they are exhausted after certain tasks, for example in tears after the school day.

The INPP approach can accurately detect NMI, then tailor a movement programme to fundamentally overcome this NMI.
