Based on the research of Peter Blythe and Sally Goddard Blythe at the Institute for Neuro-Physiological Psychology (INPP) in the UK, Primitive Reflex Therapy assesses the client for any retained primitive reflexes or undeveloped postural reflexes which may be the underlying cause of difficulties with reading, writing, balance, coordination and movement, as well as sensory hypersensitivity, concentration issues and bedwetting.

Once the reflexes have been identified, appropriate treatment is given to assist the primitive reflexes to integrate and the appropriate postural reflexes to emerge, allowing proper maturation of the child's central nervous system.
