A method for analyzing gait is provided for a system including multiple accelerometers. The method includes: for each time point and each accelerometer, calculating a root mean square (RMS) value according to the accelerations sensed on sensing axes of the corresponding accelerometer; calculating a cross correlation coefficient according to the RMS values of a first accelerometer and a second accelerometer; calculating a first auto-correlation coefficient of the RMS values of the first accelerometer; calculating a second auto-correlation coefficient of the RMS values of the second accelerometer; and calculating a first gait index according to the cross correlation coefficient, the first auto-correlation coefficient, and the second auto-correlation coefficient.
