The Homeostasis-Enrichment-Plasticity (HEP®) Approach for Premature Infants with Developmental Risks: A Pre-Post Feasibility Study

: The environmental enrichment (EE) framework has inspired several early intervention (EI) approaches. This study evaluated the feasibility, safety, caregiver acceptance, and satisfaction of implementing the HEP Approach intervention, a novel EI model based on the EE paradigm. Outcome measures for motor development, individual functional goals, sensory functions, caregiver-provided environmental affordances, and motivation for movement were examined.
