Pervasive Developmental Disorders（PDD）is a general term that includes Autistic Disorder, Asperger Syndrome, Rett Syndrome, Childhood Disintegrative Disorder, High Functioning Pervasive Developmental Disorder, and unspecified PDD. Among PDDs, those without Intellectual disabilities are called High Functioning Pervasive Developmental Disorder（HFPDD, generally Hight Functioning PDD）. It is a type of Neurodevelopmental disorder that is thought to be caused by microlesion abnormality in an innate brain disfunction. It has characteristics such as deterioration of sociality due to impaired communication ability and difficulty in social adaptation due to its own commitment. Although there are many books about Developmental disabilities themselves and how to interact with children with developmental disabilities, most of them only explain unique behavioral characteristic such as the aggressiveness of children with Developmental disabilities. On the other hand, as things stand, little is still known that children with Developmental disabilities themselves have a lot of physiological difficulties as a background to have to take such actions. It is said not clear why Developmental disabilities develop. Many of children receive drug therapy or psychological treatment, which must be said to be aimed at only alleviating behavior in question. The condition in which the autonomic nerves do not function properly is physically and mentally painful, and it often prevent them from performing daily activities. In this study, we focus on physiological difficulties that children with Developmental disabilities have and aim to reduce and alleviate secondary symptoms caused by stress, tension, physical stiffness, etc. caused by those difficulties. Aromatherapy treatments were performed for a client with High Functioning PDD, 8 times in total, with 1 course every 7 days, and changes in QOL were observed using the KK scale method.

Osteoarthritis of the hip is a disease in which deformation is caused by wear and destruction of the articular cartilage of the hip joint. Symptoms, such as inguinal pain, limitation of the range of motion, intermittent claudication (Trendelenburg’s gait, antalgic intermittent claudication), and joint deformation (leg length discrepancy), can manifest. The mean age of onset is 40-50 years old, and the male: female ratio of the prevalence is 1:1-4, demonstrating that the disease tends to develop more frequently in females. While the causative disease can be unclear, the disease is divided into 2 types: the primary type in which wear or degeneration of articular cartilage occurs, and the secondary type in which it is induced following the sequelae of a certain disease. In Japan, many cases are secondary, especially due to past medical history of acetabular dysplasia and developmental dysplasia of the hip. Frequent additional risk factors include occupations that involve the handling of heavy goods, traumatic disease, and a potential genetic influence. In western countries, occupations that involve standing for a long time, athlete-level sports, and obesity are included among the risk factors. In this investigation, subjects with complaints of severe swelling of the lower limb, inguinal pain and difficulty in walking due to the influence of osteoarthritis of the hip underwent body treatment with essential oils once weekly, for 8 weeks, and changes in QOL were observed from the holistic viewpoint using the KK scale.
