Fig. 2From: Symmetry function in gait pattern analysis in patients after unilateral transfemoral amputation using a mechanical or microprocessor prosthetic kneeGraphs presenting variability of the axial symmetry function in relation to the duration of the gait cycle for the amputated limb (solid line) ± average standard deviation (dashed line) for MicPK group (on the top) and MechPK group (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
