Key result
Stress assessment using mobile NIRS showed a higher correlation with salivary amylase levels when using variability and time-series data compared to single time point measurements.
Why the study?
Previous studies reported a relationship between stress and brain activity via NIRS, but whether salivary amylase levels relate to brain activity during the trail-making test using mobile NIRS required evaluation.
Does time-series analysis of hemoglobin concentration using mobile NIRS improve the accuracy of stress assessment compared to single time point measurements?

Hypothesis-generating for mobile NIRS in stress assessment; leaves open validation before any clinical use.
Previous studies have reported a relationship between stress and brain activity, and stress has been quantitatively evaluated using near-infrared spectroscopy (NIRS). In the present study, we examined whether a relationship exists between salivary amylase levels and brain activity during the trail-making test (TMT) using mobile NIRS. This study aimed to assess stress levels by using mobile NIRS. Salivary amylase was measured with a salivary amylase monitor, and hemoglobin concentration was measured using Neu's HOT-2000. Measurements were taken four times for each subject, and the values at each measurement were evaluated. Changes in the values at the first-second, second-third, and third-fourth measurements were also analyzed. Results showed that the value of the fluctuations has a higher correlation than the comparison of point values. These results suggest that the accuracy of stress assessment by NIRS can be improved by using variability and time-series data compared with stress assessment using NIRS at a single time point.
