목적 : 뇌졸중 환자의 편측무시와 시각적 주의력에 대한 Dynavision의 훈련 효과를 알아보는 것이다. 연구방법 : 편측무시 증상을 나타내는 좌측 편마비 뇌졸중 환자를 대상으로 개별실험 연구 방법(single subject research design) 중 AB 설계를 사용하였다. 기초선 기간에서는 Dynavision을 이용한 치료를 하지 않고 시각적 주의력을 대변하는 Dynavision 불빛에 대한 반응 시간과 반응횟수를 4회기 동안 측정하였다. 치료 기간에는 Dynavision을 이용한 치료 후 반응시간과 반응횟수를 측정하였다. 치료 프로그램은 visual tracking, self-paced, digital flash 프로그램으로 구성하였고 3주 동안 12회기를 시행하였다. 치료 전 편측무시 증상의 변화를 알아보기 위해 선나누기 검사(line bisection test)를 실시하였다. 결과 : 대상자는 기초선 기간보다 치료 기간 동안에 시각 자극에 대한 반응횟수가 증가되었고 반응시간은 감소되었다. 또한 Dynavision 치료 후에 선나누기 검사의 오류 정도가 감소하였다. 결론 : Dynavision은 뇌졸중 환자의 편측무시 증상과 이와 관련된 시각적 주의력을 향상 시키는 치료에 유용하게 사용될 수 있는 도구이다.

The purpose of this experiment was to investigate the applicability of audio-visual modeling for improving the efficiency of rehabilitative programs by analyzing the effects of observing these various models on the capacity of stroke patients to perform upper limb activities. Twenty-one stroke patients participated in the experiment and were randomly assigned to either task modeling, sport modeling, or control group. During 2 weeks of intervention, subjects in all groups participated in the physical practice of experimental tasks. These tasks comprised of a Nine Hole Peg Test, the Jebsen-Taylor Hand Function tests, and locomotion. These tasks were performed 5 days a week, 30 min per day. In addition to the physical practice, the task modeling group observed a model performing experimental tasks and locomotive activities for 20 min, while the sport modeling group observed a model performing various sport activities for 20 min. Subjects' ability to perform the experimental tasks was measured 3 times, before, immediately after, and 1 week after the intervention. Analyses of the capacity to perform upper extremity activities displayed significant improvement from the pre-test to immediate and delayed post-tests in all groups. However, the amount of improvement was the highest in the task modeling group. The task modeling group was superior to the control group in the post-test of all experimental tasks, whereas the sport modeling group did not display significant differences from the control group. These results suggest that audio-visual modeling can be used as an effective cognitive intervention for facilitating the rehabilitation of stroke patients, and its rehabilitative effect can be maximized when the program is comprised of performance scenes directly related to the target task.

The purpose of this study was to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation on a visual analysis scale and functional visual analysis scale regarding functional capacity. A total of 7 consecutive patients with the complaint of patellofemoral pain syndrome who received this diagnosis from a sports medicine physician were recruited to assess the effect of rehabilitation exercise and neuromuscular electrical stimulation (NMES) on Visual Analog Scale (VAS) and Functional Visual Analog Scale (FVAS), functional capacity patients with patellofemoral pain syndrome. The exercise rehabilitation consisted of a complex training program requiring five treatments a week for eight weeks. The training program consisted of four phases, and each lasted for two weeks. Statistical analyses were one-way ANOVA with repeated measures. The results were as follows: (1) There were significant differences in the VAS and FVAS during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.01). (2) There were no significant differences in the functional capacity during 8-weeks of rehabilitation exercise and neuromuscular electrical stimulation (p<.05). In conclusion, at the end of the eight weeks of this rehabilitation program and neuromuscular electrical stimulation, a significant reduction was found in VAS and FVAS, but there was no significant difference in functional capacity at the end of the treatment.
