Full Step Cycle Kinematic and Kinetic Comparison of Barefoot Walking and a Traditional Shoe Walking in Healthy Youth: Insights for Barefoot Technology

Figure 1

Joint moment (a, b, c), joint power (d, e, f), and joint angle (g, h, i) at the hip (a, d, g), knee (b, e, h), and ankle (c, f, i) in the sagittal plane during the gait cycle. On the curve of joint moment, the extension moment is graphed as a positive value above the horizontal axis, while the flexion moment is graphed as negative values below the horizontal axis. On the curve of joint power, generated power was graphed as a positive value above the horizontal axis, while absorbed power was graphed as a negative value below the horizontal axis. Curves show the mean value and one standard deviation for walking barefoot (blue dashed line) and neutral shoe (pink solid line), the value that is of significant difference was highlighted in red (for the duration from initial contact phase (IC) to loading response phase (LR)) and in green (for the duration from preswing phase (PSW) to initial swing phase (ISW)). Points of significant differences and ^#points of very significant differences are marked on the curve.
