Structural similarity index between the goniometer data and the corresponding synthetic gait patterns. The first and second rows show the goniometer data and synthetic data, respectively. The vertical load, thigh, knee, and ankle angles are represented by black, green, red, and blue lines. The third row shows the dissimilarity between the data, with darker colors indicating lower similarity. Most of the differences were observed during phase transitions (e.g., from stance phase to swing phase). The overall similarities for LGW, ascending stairs, and descending stairs were 0.91, 0.97, and 0.96, respectively
