Measured data of deceleration perturbation for Impulse method

Measured data of the expriment with intermittent deceleration perturbation. Data contain the speed of treadmill and the leg motion of human subjects

Estimated phase response curve (PRC) using the impulse method.

<p>The gray points are the phase variation for each impulse perturbation. Data from all trials of all subjects are displayed. The black curve is an average of the points within (A) 10% and (B) 1% of the walking cycle. The gray area around the curve is the standard deviation. The gray lines and gray cross-hatched areas are touch-down/lift-off timings and their standard deviations.</p

Measured data of acceleration perturbation for Impulse method

Measured data of the expriment with intermittent acceleration perturbations. Data contain the speed of treadmill and the leg motion of human subjects

Phase transition curve with a stronger perturbation than in the actual experiment (3<i>μ</i>_<i>I</i>).

<p>The black curves are the average phase transition curves of each subject. The gray dotted line is <i>ϕ</i>_<i>n</i>+1 = <i>ϕ</i>_<i>n</i>. The gray lines and gray areas are timings of the touch-down and lift-off and their standard deviations.</p

The relationship between cycle length and stance/swing phase.

<p>(A) Results of acceleration and deceleration perturbation are displayed as points. Linear regression results for each subject are displayed as lines. (B) Regression coefficient of linear regression. Results are the average and standard deviation for each subject.</p

Histogram of the walking phase after transition by the perturbation.

<p>The distribution of post-transition phases for 500 points uniformly selected before the transition are displayed using a histogram with 50 bars. The results are shown using the average and standard deviation of all subjects. The gray lines and gray areas are timings of touch-down/lift-off and their standard deviations.</p

The deviation (seconds) between the peak timing of phase response curve and the nearest touch-down or lift-off timings.

<p>The different color bars show the results for each subject. Each bar represents the average and standard deviation of 5 PRCs obtained for each subject.</p

Estimated phase response curve (PRC) using the WSTA method.

<p>The black curve is the average PRC for all the trials of all the subjects and gray area around the average represents the standard deviation. The gray lines and gray cross-hatched areas are the touch-down/lift-off timings and their standard deviations.</p

Average (standard deviation) of peak phase around touch-down and lift-off phase.

<p>Values are in seconds.</p
