Physical therapy, occupational therapy, and cognitive therapy of the same intensity and time were applied to all patients. In addition, two occupational therapists conducted treatment for unilateral spatial neglect. One therapist conducted conventional rehabilitation programs for the control group, such as visual tracking, reading and writing, drawing and copying, and puzzles, while the other conducted the virtual reality treatment on the VR group. Such treatments were applied for thirty minutes a day, once a day and five days a week for three weeks. The VR system (IREX system®, Vivid group, Toronto, Canada) consists of a monitor, a video camera, computer-recognizing gloves, and virtual objects (Fig. 1-A). The video camera recognizes movements or position of a patient and transfers him or her to the virtual space. The computer gloves read responses of a patient to the virtual reality. All patients sat in a wheelchair because they could not be trained while standing. The VR training is composed of three programs at a time. "Bird and Ball" is a program in which a patient touches a flying ball with his or her hand and turns it into a bird (Fig. 1-B). The second program, "Coconut," is a program in which a patient catches a coconut falling from a tree while moving around (Fig. 1-C). In the third program, "Container," a patient moves a box carried in a container to the opposite side (Fig. 1-D). In the three programs, patients were told to use non-paretic right hands against the left stimulation. When patients were not able to respond to the stimuli, the therapist encouraged them to respond. Calibration was made for three minutes before the start of the training. There were 150 seconds of resting between programs and 30 seconds between treatments. Each session was repeated three times.
