Abstract

In this study, the definition of "digital therapeutics" was clarified by examining related studies, and the development trend of digital therapeutics at the domestic level was investigated. Further, research data and technologies applied to various communication disorders since 2015 were analyzed. From all these, digital therapeutics can be defined as software that can support evidence-based treatment when used on patients to prevent, manage, and treat disorders With huge investments and research efforts increasingly made in the field of digital therapeutics, 17 of the 22 studies examined were on digital therapeutics applied in the treatment of language disorders. In the research papers examined, the technologies applied were virtual reality and augmented reality, with augmented reality used in most cases. The effects of applying digital treatment were positive, and most studies focused on content development in relation to the development of digital treatment, although one study was conducted for app development. Future studies could examine the application of digital therapeutics to more diverse communication disorder subjects. Active government support is expected in developing more sophisticated software that can be applied using a wider range of technologies in the field of digital therapeutics to treat more communication disorders.

본 연구는 '디지털 치료제'의 정의를 확인하기 위해 이와 관련된 연구들을 통해 확인해보고, 디지털 치료제의 개발 동향을 국내 수준에서 조사해 보았다. 그리고 2015년 이후 연구 자료를 대상으로 디지털 치료제가 의사소통장애 분야에서 언어장애와 말장애 대상자들 중 어떤 장애 분야에 적용된 연구가 진행되어 왔는지 그리고 어떠한 기술이 적용된 연구가 이루어 왔는가 역시 분석해 보았다. 그 결과 디지털 치료제는 소프트웨어라는 점, 예방·관리·치료하기 위해 환자에게 적용되는 소프트웨어적인 치료제이며 근거 기반 치료를 제공하는 소프트웨어로 정의할 수 있다. 디지털 치료제와 관련해서 엄청난 투자를 진행하고 있고 이와 더불어 관련된 연구도 지속적으로 증가하고 있음을 확인할 수 있었다. 다음으로 의사소통장애 대상자에게 디지털 치료제를 적용한 2015년 연구 사례를 분석한 결과 언어장애에 해당하는 연구가 전체 22편 중에서 17편으로 주를 이루었고, 말장애 분야 연구, 일반아동을 대상으로 한 연구, 전문가를 대상으로 한 연구가 있었다. 디지털 치료제에 적용될 수 있는 다양한 기술 중 가장 많이 적용된 기술은 가상현실과 증강현실이었다. 가상현실보다는 증강현실을 적용한 연구가 대부분이었음을 확인할 수 있었고 AI를 적용한 연구도 있었다. 그리고 디지털 치료제의 적용 후 효과는 대부분 긍정적으로 나타났고, 디지털 치료제 개발과 관련해서 대부분은 콘텐츠 개발에 중점을 두고 있으나 한 편의 연구는 앱 개발을 위해 진행된 연구다. 향후 연구에서는 보다 다양한 의사소통장애 대상자에게 적용 가능한 소프트웨어를 개발하고 보다 광범위한 기술을 적용한 연구들이 꾸준히 이루어지고 이러한 분야에 대한 정부의 적극적인 지원도 이루어지기를 기대해 본다.
