What is the Psychomotor Development Index?
The Psychomotor Development Index or PDI is a scientifically mainstream accepted rating or score designed to measure the progressive acquisition of skills involving both mental as well as motor activities in humans. It evaluates several types of abilities including body control, large muscle group coordination, manipulation skills of the hands and fingers, and the ability to recognize objects by touch. It is used with infants to assess overall physical and motor skill ability and confirm whether the infant’s development in these areas is on track with their age.
