Biomechanical Modalities in Neonatal Postural Ergonomics and the Neurobiology of the Mammalian Transport Response: A Systematic Review

This review synthesizes current pediatric literature on the physiological, neurological, and anatomical adaptations activated during dynamic infant carrying and sleep-soothing practices. Utilizing clinical neurobiological data regarding the mammalian transport response, we analyze the vestibular-parasympathetic cascade that regulates neonatal cardiac intervals and reduces distress vocalizations during upright carrying. Furthermore, this paper audits structural ergonomic safety criteria, evaluating the biomechanical load distribution of diverse carrier textile structures (including TENCEL™ Modal, woven cotton, linen, and 3D polyester mesh) on the developing infant spine and hip joints. Specialized focus is directed toward maintaining the physiological C-curve (spinal kyphosis) and the orthopedic M-position to prevent developmental hip dysplasia and eliminate the risks of silent positional asphyxia induced by forward chin-to-chest neck flexion.
