In the parametric analysis of electromyographic (EMG) signals, we have to deal with the complicated behavior of a lot of parameters in the time domain. We have employed the less-biased time varying AR model parameters estimated by locally quasi-stationary processing. Hence, we propose the time-suppressed representation of the behavior, projecting the time series of less-biased time-varying vectors onto three standard planes. The vector is composed of the k parameters, K^(i) for i= 1, 2, 3.Therefore, the mutually perpendicular coordinates are K^(1), K^(2) and K^(3). Significant changes which appear to result from the muscle dynamics are observed in the K^(2), K^(3) plane, as the masticatory function is recovered.Frontiers of medical and biological engineering = Frontiers of medical and biological engineering332112141991Japanese Society for Medical and Biological Engineering09213775AA10728091publisherhttps://niigata-u.repo.nii.ac.jp/?action=repository_action_common_download&item_id=1680&item_no=1&attribute_id=20&file_no=12019-07-29
