Rehabilitation of Developmental Disorders

Associate Professor
Toshihiro Kato, OTR, Ph.D.
Recent advancement of medical technologies has enabled human beings to save lives of many children. This fact also indicates that some children have to grow up and develop with physical disabilities, mental disabilities, or higher brain dysfunctions, caused by brain disorders. The prevalence of developmental disabilities (DD) has been increasing, and the government has started support projects.
We conduct research on assessment and intervention for individuals who need support through developmental process. We are also committed to educating therapists working in this field.

Research and Education

Our laboratory focuses on two research projects. The first project aims to develop occupational therapy assessment and intervention methods for DD, mainly autism. Currently, the number of children with DD, who take occupational therapy, is increasing rapidly. However, researches regarding effectiveness of occupational therapy through sensory integration approaches are limited and inconclusive. We are focusing on 1) development of objective assessment tools, 2) therapeutic effectiveness of interaction between therapists and children, 3) effectiveness of school-based occupational therapy.
The second project is on occupational therapy for individuals with cancer. The five-year survival rate of Leukemia, which is the highest in incidence rate among various pediatric cancers, is reported to be 90% at present. However, many of the surviving children have difficulties adapting in schools and at home. Thus, we attempt to investigate assessment and intervention for them.
There are many research fields: hospitals, child development support centers, preschools, regular schools, and special schools.
