Figure 2From: Recommended number of strides for automatic assessment of gait symmetry and regularity in above-knee amputees by means of accelerometry and autocorrelation analysisBlock diagram of the algorithm for automatic computation of Ad1 and Ad2. Mv and Mt are the value and the time shift, respectively, of one maximum in the autocorrelation sequence. Maxima A and B are the first candidates to become Ad1 and Ad2. A1 and B1 are (possible) second candidates.Back to article page
