Fig. 8: Plantar pressure.
From: The SoftFoot Pro: an anthropomorphic and adaptive soft articulated prosthetic foot
Plantar pressure distribution (kPa) during (a–f) level walking (averaged over 8 strides, n = 8) and (g–n) rectangular obstacle negotiation (right foot stepping on the obstacle, one single stride). a–c, g–i Peak pressure values. d–f, l–n Average peak values. a, d, g, i Able-bodied footprints are from an unimpaired subject, while those (b, e, h, m) of the SoftFoot and (c, f, i, n) of the carbon foot VariFlex (by Ӧssur) are from the same subject walking on the prosthetic feet through customised walking boots. The centre of pressure trajectory is shown in fuchsia.
