Joint kinematics recombined from the PCSs of PCV 2 The definitions of the abbreviations in the central tendency graph are as follows: Post.: Posterior. Tilt, Ant.: Anterior Tilt, Flex.: Flexion, Ext.: Extension, D.F.: Dorsi-flexion, P.F.: Plantar flexion, L.U.: Left Side Up, R.U.: Right Side Up, Add.: Adduction, Abd.: Abduction, I.R.: Internal Rotation, E.R.: External Rotation, Ever.: Eversion, Inv.: Inversion. Gray high-lighted area indicates the instance of the toe off (transition of stance phase and swing phase). It has certain width because present study did not separate stance phase from swing phase at the time-normalization procedure. Because there is a significant negative correlation between the PCVs and the Two-Step test scores, +3SD waveform can be interpreted as representing an exaggerated gait pattern consistent with older people with low scores on the Two-Step test, whereas -3SD waveform can be interpreted as representing an exaggerated gait pattern consistent with older people with high scores on the Two-Step test. a sattigal pelvis angle, b frontal pelvis angle, c horizontal pelvis angle, d sagittal hip angle, e frontal hip angle, f horizontal hip angle, g sagittal knee angle, h frontal knee angle, i horizontal knee angle, j sagittal ankle angle, k frontal ankle angle, l horizontal ankle angle
