Fig. 2
Superposition of individual kinetics. The top panels show hippus kinetics in the supine position with (a) short-duration (1.21 ± 0.28 s), (b) intermediate-duration (1.80 ± 0.19 s), and (c) long-duration (2.74 ± 0.40 s). The bottom panels show hippus kinetics in the standing position with (d) short-duration (1.37 ± 0.20 s), (e) intermediate-duration (1.80 ± 0.19 s), and (f) long-duration (2.55 ± 0.33 s). All hippus kinetics were aligned relative to the start of the constriction phase and were normalized in terms of amplitude using the min-max function. Note the hippus good reproducibility, highlighting an individual signature. To avoid overloading the figure, participants with fewer than 3 usable hippus were not represented.
