From the beginning of my studies, I was sure that I could contribute to the field of paediatrics, which has always fascinated me. We can say that nowadays, we are discovering more and more children affected by Autism Spectrum Disorder (ASD) and parents who are looking for effective treatments that show satisfactory results. With this in mind, we decided to carry out a literature review so that we could observe the relationship between Hug Therapy and Sensory Integration in this audience of children, and point to data that would provide us with positive results, or not, with a scientific basis, so that we could present them through this work. I hope you can improve your knowledge by reading this book, which was written with great dedication and affection.
