Tactile defensiveness is a common feature in neurodevelopmental disorders (NDDs). Since the first studies, tactile defensiveness has been described as the result of an abnormal response to sensory stimulation. Moreover, it has been studied how the tactile system is closely linked to socio-communicative development and how the interoceptive sensory system supports both a discriminating touch and an affective touch. Therefore, several neurophysiological studies have been conducted to investigate the neurobiological basis of the development and functioning of the tactile system for a better understanding of the tactile defensiveness behavior and the social touch of NDDs. Given the lack of recent literature on tactile defensiveness, the current study provides a brief overview of the original contributions on this research topic in children with NDDs focusing attention on how this behavior has been considered over the years in the clinical setting.
触觉防御是神经发育障碍（NDDs）的一个常见特征。自最初的研究以来，触觉防御一直被描述为对感觉刺激的异常反应的结果。此外，人们还研究了触觉系统如何与社会交往发展密切相关，以及内感受觉系统如何支持辨别性触摸和情感性触摸。因此，已经进行了几项神经生理学研究，以调查触觉系统发育和功能的神经生物学基础，以便更好地理解NDDs的触觉防御行为和社交触摸。鉴于最近缺乏关于触觉防御的文献，本研究简要概述了关于这一研究主题对患有NDDs的儿童的原始贡献，重点关注多年来在临床环境中如何看待这种行为。
