婴儿喂养是神经系统发育中的一个重要里程碑，其定义是肌肉、周围神经和脑干核团的协调。在婴儿中，乳汁流量通常仅限于改善喂养性能，而没有治疗吸奶和吞咽过程中的潜在缺陷。在奶瓶喂养过程中，通过乳头的感觉信息来调整神经运动反应是一种基于生理学干预的未知途径。在这项研究中，我们评估了乳头孔大小和乳头硬度的差异如何影响吸盘肌肉的激活和随后的运动。我们制作了四个不同孔大小和硬度的奶瓶乳头，以确定乳头特性的变化如何影响仔猪的吸吮行为。我们的结果表明，来自乳头的感觉信息影响吸吮运动输出。奶流率越大，乳头孔的大小和僵硬程度越大，肌肉活动和运动能力就越强。此外，我们的结果表明，感觉运动干预更适合于调节舌头功能，而不是下颌运动，因为对感觉信息的反应更大。了解感官信息如何影响婴儿喂养有助于促进有效的婴儿喂养。
Infant feeding is a critical neurological milestone in development defined by the coordination of muscles, peripheral nerves, and brainstem nuclei. In infants, milk flow rate is often limited to improve feeding performance without treating the underlying deficiencies in the sucking and swallowing processes. Modification of the neuromotor response via sensory information from the nipple during bottle feeding is an unexplored avenue for physiology‐based interventions. In this study, we assessed how differences in nipple hole size and nipple stiffness affect sucking muscle activation and subsequent movement. We fabricated four bottle nipples of varying hole size and stiffness to determine how variation in nipple properties affects the sucking behavior of infant pigs. Our results demonstrate that sensory information from the nipple affects sucking motor output. Nipple hole sizes and stiffnesses with a larger milk flow rate resulted in greater muscle activity and kinematic movement. Additionally, our results suggest that sensorimotor interventions are better directed toward modulating tongue function rather than the mandible movements due to a greater response to sensory information. Understanding how sensory information influences infant feeding is instrumental in promoting effective infant feeding.
