摘要
This paper reports the preliminary results of an analysis of surface EMG signals obtained from rehabilitated patients with lower back problems using discrete wavelet transform techniques. In our study, 12 patients with lower back pain were tested before and after rehabilitation. The reaction time difference (before and after rehabilitation) from the erector spinae muscle caused by sudden loading was determined. The results indicated that the reaction time after rehabilitation was shorter than that before rehabilitation for about 45% of the tested cases. (C) 1998 Elsevier Science Ltd. All rights reserved.
