This study applied dynamic time warping (DTW) to lower-limb gait motion in water with a slow to fast pace compared with those on land at a comfortable pace; this was done for 15 participants to examine if the result obtained would be similar to previous study irrespective of gait pace in water. The correlation between the DTW results and the joint angle difference in the two environments was also investigated to clear the reason for the result of DTW. Consequently, DTW detected incomplete motion in the water at any pace in the hip joint just before the toe-off, which moderately correlated (r = 0.59) with the peak extension angle difference of the hip joint between the two environments. Therefore, an increasing extension motion in the hip joint just before the toe-off during gait in the water would be suggested for simulating gait motion on land.
