가성무시(pseudoneglect)란, 신경학적 손상이 없는 정상인들이 무시증후군(visuospatial neglect)을 탐지하는데에 가장 많이 사용하는 선 이등분(line bisection)검사에서 좌측으로 치우쳐서 중심점을 표시하는 현상으로써, 우반구 손상을 입은 환자들이 공간의 좌측을 무시하고 중심점 우측으로 선을 이등분하는 것과는 반대된다. 본 연구는 시각적 주의에 영향을 미치는 가성무시현상에 대해 선 이등분과 선 사등분 전략을 적용한 도로에서의 모의운전(driving simulation)과 지필검사를 이용하여 확인하였다. 지필검사에서 선 이등분점과 좌측 사등분점이 유의미하게 좌측으로 치우친 반면, 우측 사등분 점은 유의미한 좌측 치우침을 보이지 않았다. 모의운전에서는 차량의 우측 치우침이 도로 조건과 관계없이 나타났으나 각 도로에 대한 상대적 치우침을 분석한 결과, 선 이등분 조건의 도로 1이 가장 많은 좌측 치우침을, 우측 선 사등분 조건의 도로 2가 가장 적은 좌측 치우침을 나타내어 지필검사와 모의운전의 결과가 유사하며 모두 좌측 치우침 현상이 있음을 확인했다. 또한 우측 치우침에 대한 원인으로 중앙선 회피효과를 분석한 결과, 중앙선 우측에서 주행한 도로 2와 4에서 회피경향이 나타났다. 본 연구에서는 가성무시가 운전 중에 유의미하게 나타남으로써 일상생활에서도 이와 같은 현상이 존재함을 나타냈다.

Purpose: Aim of this study was to investigate whether there are ipsilateral motor deficits for visuospatial accuracy and fine movements by making a comparison between stroke patients and healthy subjects. We examined whether ipsilateral motor deficits are influenced by the level of functional movements and muscle strength of the upper and lower extremities of the affected side. Methods: Thirty post-stroke subjects and 20 normal aged matched subjects were recruited. Outcome measures for less-affected side were the tracking task and nine-hole pegboard test. Fugl-Meyer test and motricity index were applied for the measurement of functional movements and muscle strength of affected side. Results: Tracking task and nine-hole pegboard test was significantly different between control and experimental group. In terms of accuracy index according to tracking, the experimental group showed a lower accuracy index in the MCP joint than the control group. However, there were no significant difference relation between the level of motor function of the affected side and the motor deficit level of ipsilateral side. Conclusion: Ipsilateral motor deficits may have significant clinical implications. It needs to be noted that although many patients, families, and medical staff are focused only on motor deficits of the affected side, motor deficits of the sound side can cause difficulties in daily living movements requiring delicate movements. In addition, there was no significant correlation between the level of motor function of the affected side and motor deficits of the sound side.

Purpose: The purpose of this study was to examine the effects of a cognitive training program on neurocognitive task performance and activities of daily living (ADL) in patients who had a stroke. Methods: The research design for this study was a nonequivalent control group non-synchronized design. Patients were assigned to the experimental (n=21) or control group (n=21). The experimental group received a 4-week cognitive training program and usual care (i.e., rehabilitation service), while the control was received usual care only. Cognitive function was measured with a standardized neurocognitive test battery and ADL was assessed at baseline and one and two months after completion of the intervention. Repeated measures ANOVA was used to determine changes in cognitive function and ADL over 2 months. Results: The interaction of group and time was significant indicating that the experimental group showed improvement in attention, visuospatial function, verbal memory, and executive function compared to the control group which had a sustained or gradual decrease in test performance. A significant group by time interaction in instrumental ADL was also found between the experimental group with gradual improvement and the control group showing no noticeable change. Conclusion: Findings show that the cognitive training program developed in this study is beneficial in restoring cognitive function and improving ADL in patients following a stroke. Further study is needed to investigate the long-term relationship between cognitive training participation and cognitive improvement and effective functioning in daily living.
