2-3-10. Development of cerebral activity examination that is simple and robust against repetition by using wearable NIRS

Abstract

Monitoring of cerebral activity during long-term therapy such as occupational therapy is useful for the development of new protocols and assessments of the therapy. For clinical use, the authors tried to develop an examination by using a wearable Near infra-red Spectroscopy (NIRS) device with a neurocognitive task that is robust against repetition (habituation). The study was approved by the Ethics Committee of Gunma University Graduate School. Participants were fourteen healthy university students. We used a WOT-100, ten channel wearable NIRS device. Each participant underwent three tasks (deceitful reverse rock paper scissors, Stroop test, animal Stroop test) on a zero day, one week after, two weeks after, and three weeks after. Then the integral values of the oxyhemoglobin during the task were calculated. Stroop task was the only task with minimum habituation especially in the right frontal lobes. We concluded that the Stroop task was the most favorable of the three at this time.
