ABSTRACT:
A mastication monitoring device1is provided with a probe2which is attached to a cheek in order to detect the concentration of reduced hemoglobin in the masticatory muscles. A photodetector22of the probe2detects light scattered in the masticatory muscles and delivers a signal of the amount of light received to a signal processing unit3. The signal processing unit3computes the reduced hemoglobin concentrations (time-series changes) from the signals of the amount of light received, and further computes outputs S (time-series changes) corresponding to the time-series changes in the reduced hemoglobin concentrations. A mastication iteration counting unit41detects peaks in periodical changes of Sd which is the difference between the output S and the moving average value Sma of the output S and counts the peaks in periodical changes of Sd as the mastication iterations.
