ABSTRACT
OBJECTIVE:
To investigate the effects of a stimulus response task using virtual reality (VR) for unilateral spatial neglect (USN).DESIGN:
Double-blind randomized controlled trial.SETTING:
Acute phase hospital where stroke patients are hospitalized.PARTICIPANTS:
The participants were 42 patients (N=42) with right-hemisphere cerebral damage who had been experiencing USN in their daily lives. They were randomly assigned to 3 groups a stimulus response task with a background shift (SR+BS group), a stimulus response task without a background shift (SR group), and an object gazing task (control group).INTERVENTIONS:
The stimulus response task was to search for balloons that suddenly appeared on the VR screen. A background shift was added to highlight the search in the neglected space. The control task was to maintain a controlled gaze on a balloon that appeared on the VR screen. The intervention period was 5 days. MAIN OUTCOMEMEASURES:
The primary outcome was the participants' scores on a stimulus-driven attention test (SAT) using the reaction time. The stimuli of the SAT were divided into 6 blocks of 3 lines on each side (-3 to +3). The secondary outcomes were their scores on the Behavioral Intention Test conventional, Catherine Bergego Scale, and straight ahead pointing tests.RESULTS:
In the SAT, there were significant interaction effects of reaction time between time and group factors in left-2, right+2, and right+3. The SR+BS and SR groups showed significant improvements in the reaction time of left-2 and right+3 compared with the control group. Moreover, the SR+BS group showed a significant improvement in the reaction time of left-2, which was the neglected space, compared with the SR group. However, there were no significant interaction effects of Behavioral Intention Test conventional, Catherine Bergego Scale, and straight ahead pointing.CONCLUSIONS:
Our results suggest that the use of stimulus response tasks using VR combined with background shifts may improve left-sided USN.Palabras clave
