[Purpose] This study aimed to explore the current use of developmental rehabilitation services in 17 major cities in South Korea. [Methods] To this end, data was collected and analyzed from 2,160 service providers as of August 2021. [Results] First, it was found that rehabilitation services in Speech rehabilitation, art-based psychology, and sensory development are the most frequently used across most disability types. Second, services are used most frequently by children under the age of 6(29.1%), and service users are generally distributed in the lower age group. Third, the total average price per session is 41,610 South Korean won and is generally higher in metropolitan areas, such as Seoul and Gyeonggi. Regarding service types, the price of sensory development, play-based psychological rehabilitation, and physical exercise development were found to be highest, in that order. Fourth, the most rehabilitation institutions are in Gyeonggi, Seoul, Gyeongnam, Busan, and Gyeongbuk, in that order, while the number of practitioners is higher in Gyeonggi, Seoul,Busan, and Incheon. Lastly, the waiting lists are longest in Seoul, Gyeonggi, Incheon, and Jeonnam, and the average waiting period is longer in Seoul, Incheon, Gyeonggi, and Gangwon. [Conclusion] Based on these results, suggestions for the efficient operation of developmental rehabilitation services are presented.
