Abstract

Objective : This study aim is to identify whether smooth pursuit eye movement(SPEM) using portable device can alleviate chronic hemispatial neglect. Methods : We applied smooth pursuit eye movement to one chronic hemispatial neglect patient. Experimental duration was total 4weeks - 1week baseline, 2weeks SPEM intervention, 1week 2nd. baseline. The intervention was 10 SPEM sessions (30min each, 1session daily, from Monday to Friday) over a period of 2weeks. The neglect test carried out 5 times a week. The SPEM was provided on the screen when patient sat in front of the screen(8.4 inch tablet pc, distance 40cm). The SPEM video that the 24 yellow squares moving coherently from the right to the left side. Patients were instructed to perform smooth pursuit eye movement without head and neck movement. Results : As a result of the SPEM for 2weeks, the degree of neglect tended to decrease compared to baseline A. The degree of the LBT tended to increase the at the baseline A'. In contrast, the SCT showed that tendency which the degree of the neglect maintained at the baseline A'. Conclusion : We identified that SPEM using portable device is effective intervention method for chronic hemispatial neglect.

목적 : 본 연구의 목적은 만성 편측무시 환자에게 휴대용 디바이스를 이용한 완곡추적 안구운동을 30분간 적용하였을 때 편측무시에 미치는 효과를 알아보는 것이다. 연구방법 : 만성적으로 편측무시를 보이는 한 명의 환자를 대상으로 8.4인치 화면의 휴대용 디바이스를 이용하여 완곡추적 안구운동을 실시하였다. 실험기간은 총 4주로 1주간의 기초선 측정과 2주간의 완곡추적 안구운동 중재, 1주간의 기초선 측정으로 이루어졌으며, 중재는 2주 동안 1일 1회, 주 5회, 회기당 30분씩 적용하였다. 편측무시는 선이분검사와 별지우기검사를 통해 매 회기 측정하였다. 완곡추적 안구운동은 시각적으로 영향을 줄 수 있는 주변의 환경을 줄이고 바른 자세로 앉아 정면에 있는 8.4인치 태블릿pc의 영상을 바라보는 것이다. 영상은 완곡추적 안구운동을 유발하기 위한 영상으로 24개의 노란색 직사각형이 끊임없이 화면 오른쪽에서 왼쪽으로 움직이는 영상이며, 영상을 보는 동안 고개의 움직임 없이 도형을 따라 안구운동을 하도록 하였다. 결과 : 2주 동안의 시운동자극 적용 결과 기초선A와 비교하여 편측무시가 감소되는 경향을 보였지만, 중재기 이후 기초선A'에서 편측무시 양상이 다시 증가하는 결과를 보였다. 결론 : 본 연구를 통해 휴대용 디바이스를 이용한 30분간의 완곡 추적 안구운동이 만성편측무시를 감소시키는데 효과가 있는 것으로 확인되었다.
