In this study, the directions of the force exerted by the arm during isometric muscle contraction were estimated by using the 24-channel functional near infrared spectroscopy (fNIRS) signal on cortical hemodynamics. In an experiment, subjects were required to perform isometric arm movements in four directions (Front: F, Right: R, Back: B and Left: L from the subjects) with the right arm while keeping a certain joint angle during the task period. Spatial and temporal feature selection were performed on the fNIRS signal to ascertain the representation of the force directions. The estimation results suggest that the FB-RL classification accuracy was approximately 70-90\%. Further, NIRS spatial parametric mapping (NIRS-SPM) analysis results suggest relation to the spatial features of the fNIRS signal which contributed for the estimation. These results indicate the possibility that statistically-significant areas give effective features for estimation the direction on the fNIRS signal. |
