Fig. 4From: Symmetry function in gait pattern analysis in patients after unilateral transfemoral amputation using a mechanical or microprocessor prosthetic kneeGraphs presenting variability of the symmetry function (relative to the norm) in relation to the duration of the gait cycle for the intact limb (solid line) ± average standard deviation (dashed line) for the MicPK group (on the top) and MechPK (on the bottom) characterizing pelvic movements in frontal (POBLI), sagittal (PTILT), and transverse (PROT) plane as well as hip joint movements in frontal (HPAA), sagittal (HPFE), and transverse (HPROT) planeBack to article page
