INPP

The Institute for Neuro-Physiological Psychology (INPP) is a UK-based private clinical and research organisation founded in 1975 in Chester, initially by Dr Peter Blythe and subsequently led by Sally Goddard Blythe . INPP specialises in identifying and addressing neuromotor immaturity - particularly persistent, retained primitive reflexes - in both children and adults .

Primitive reflexes are automatic movements present at birth, normally integrated or inhibited by the brain early in life. If these reflexes persist, they can interfere with development, affecting motor coordination, visual processing, hand-eye coordination, and perceptual and learning skills .

The INPP method employs a non-invasive, drug-free program consisting of tailored physical exercises—based on natural infant movements—to help integrate these reflexes. The typical program involves an initial developmental assessment to identify retained reflexes, followed by a personalised continuous home exercise routine of around 5–10 minutes daily. Progress is monitored through reviews every 6 to 8 weeks, and the entire program often spans 12 to 18 months .

INPP has been applied across diverse populations to support individuals facing learning difficulties—such as dyslexia, ADHD, dyspraxia—as well as emotional and behavioural challenges including anxiety and poor concentration .
