Fig. 8. (A) Pitch angle and chord angle (the angle between the chord line and the
body axis, a measure of active adjustment of limb positions relative to the
body) for one glide sequence. Values for pitch angle are positive when the
sternum marker is higher than the pelvis marker and negative when the sternum
marker is lower than the pelvis marker. The chord angle is positive when the
wrist marker is higher than the ankle marker with respect to the body axis and
negative when the ankle marker is higher than the wrist marker with respect to
the body axis. Note that as the pitch angle increases, the chord angle
decreases and vice versa. (B) Cross-correlogram for the same trial as
in A, showing maximum negative correlation between changes in pitch angle and
limb position at zero time lag. Lines represent 95% confidence interval.
