Temporal patterns of planar angles. Where, from top to bottom: F2G is the sagittal-plane angle of the 1^st metatarsal bone to the ground; S2G is the sagittal-plane angle of the 2^nd metatarsal bone to the ground; S2F is the transverse-plane angle between 1^st and 2^nd metatarsal bones; V2G is the sagittal-plane angle of the 5^th metatarsal bone to the ground; S2V is the transverse-plane angle between 5^th and 2^nd metatarsal bones; F2Ps is the sagittal-plane angle between 1^st metatarsal bone and proximal phalanx; F2Pt is the transverse-plane angle between 1^st metatarsal bone and proximal phalanx, and MLA is the angle between CAp-ST and ST-FMH projected into the sagittal plane of the foot. Mean (solid line), plus and minus a standard deviation (grey band), were calculated across 30 walking trials, 3 repetitions for each of the 10 participants. The corresponding mean value obtained in the static up-right posture is superimposed to the temporal profile (dash-dot line segment) and reported numerically within each plot.
