The purpose of this study was firstly to compare lower limb joints angular displacement between land and water-walking by dynamic time warping. Six subjects (age 30.0±5.3 yr) performed 10 m land and water-walking at self-selected speed. Ankle, knee and hip joint angular displacements were calculated from video (25Hz) and compared to the two wave forms from the dynamic time warping procedure. Results showed the ankle and knee joints demonstrated warping periods in water-walking, when compared with land-walking. However, the warping periods around toe-off was seen at the hip joint in land-walking, compared with water-walking. Overall the ankle and knee joints motion in water walking were comparable to land-walking motion. However, the hip joint kinematics during water walking were not always comparable with land walking kinematics.
