From the mid-1960s to the early 1970s, the focus of rehabilitation for disabledchildren was shifted from polio to cerebral palsy. In the mid-1970s,Hokkaido tookthe initiative in promoting early detection and rehabilitation as measures againstcerebral palsy. However,given Hokkaido’s geographical conditions,the treatmentof those with cerebral palsy who lived in sparsely populated areas was extremelydifficult. To reverse the situation, the Hokkaido government sought to develop amore effective rehabilitation system, and therefore commenced full-scale regionalsupport based on a tertiary bloc concept. In response to this scheme proposed bythe Hokkaido government, the Hokkaido Infant Rehabilitation Study Group wasestablished in 1987 with the aim of collaborating with representatives in charge ofregional rehabilitation. This year marks the 30th anniversary of the study group’sactivities. The following is a summary of the activities unprecedented in Japan inwhich the regional rehabilitation study group has been involved.
