Abstract

Objective : This study aimed to develop prototypes of "smart stacking cones" by combining ICT to evaluate and train the upper extremity function and dual task performance in patients with central nervous system impairment, and to identify the complementary point to the completion of the device through a usability test. Methods : This prototype comprised of a hardware and software system that enabled the evaluation and training of patients and the management of data obtained from patients' performance. Specific measurement variables were established so that patient performance could be measured correctly. Based on the measurement variables, a the prototype included a 'single task evaluation modes', 'dual task evaluation mode', 'single task training mode', and 'dual task training modes'. Additionally, a usability test was conducted to assess clinical applicability and overall satisfaction for the prototype. Results : The results of the usability test were generally found to be appropriate. The 'content adequacy' in the usability test was the area with the highest level of adequacy and the lowest level of inadequacy. Additionally, overall 'satisfaction' in the usability test was the area with the highest appropriate and inappropriate levels. Hence, the overall satisfaction results were unstable. Conclusion : Future studies should be conducted to identify the clinical effectiveness of the device by applying an upgraded smart stacking cone to an actual patient group.

목적 : 본 연구는 중추신경계 손상 환자의 상지기능과 이중과제 수행능력의 평가 및 훈련을 위해 개발 중인 스마트 스태킹 콘을 시제품 단계까지 개발하여, 사용성을 파악하고 수정 및 보완점을 점검하여 향후 연구 방향을 제시하고자 하였다. 연구방법 : 본 연구는 ICT 기술을 기반으로 '스마트 스태킹 콘'의 시제품을 개발하였으며, 평가 및 훈련으로부터 생성되는 피험자의 데이터를 관리할 수 있도록 하드웨어 회로 및 소프트웨어 기능을 설계하였다. 또한, 피험자의 수행을 올바르게 측정할 수 있도록 구체화된 측정변수를 설정하였으며, 이를 바탕으로 '단일과제 평가모드', '이중과제 평가모드', '단일과제 훈련모드', '이중과제 훈련모드'로 콘텐츠를 구성하였다. 또한, 개발된 시제품의 임상적 적용 가능성과 전반적인 만족도를 평가하고자 사용성 평가를 실시하였다. 결과 : 사용성 평가 결과 개발된 시제품에 대해 전반적으로 보통 이상의 수준으로 긍정적인 응답이 나타났다. 특히, '콘텐츠 적절성' 영역은 적절 수준이 가장 높게 응답된 영역이자 부적절 수준이 가장 저조하게 나타난 영역으로 확인되었고, '전반적 만족도' 영역은 매우 적절 수준이 가장 높게 나타난 영역임과 동시에 부적절 수준 또한 가장 높게 나타난 영역으로, 기기에 대한 전반적 만족도는 안정적이지 못한 것으로 나타났다. 결론 : 본 연구 결과를 바탕으로 기기를 수정하여 완성한 후 실제 환자군에게 적용해봄으로써, 기기의 임상적 효과성을 파악하기 위한 연구가 진행되어야 할 것이다.
