摘要
The objective of this study was to determine the within-and between-day reliability of spatio-temporal plantar pressure kinematic and kinetic measurements based on a novel seven segment foot model applied in patients with Psoriatic Arthritis (PsA) Nine PsA patients and matched healthy adult controls underwent three-dimensional gait analysis on two occasions one week apart using a seven segment foot model A core-set of functional variables including inter-segment kinematics kinetics spatio-temporal and plantar pressure distribution were analysed using the coefficient of multiple correlation (CMC) Bland-Altman plots intraclass correlation coefficients (ICC) and the standard error of measurement (SEM) Results showed excellent within- and between-day reliability for intersegment kinematic and kinetic data patterns with CMC values typically greater than 0 950 in a clinically stable cohort of PsA patients Between-day reliability ranged from poor to excellent for absolute CMC values Corrected CMC values were consistently higher across all variables ranging from fair to-good to excellent ICC values indicated excellent reliability for discrete spatio-temporal plantar pressure and ankle moment and power variables for both groups Reliability for ground reaction forces and kinematic discrete variables ranged from fair-to-good to excellent Standard error of measurement values ranged from 07 to 3 0 for discrete kinematic variables across both groups with greater variability in the PsA patients In conclusion intersegment kinematics and kinetics as well as spatio-temporal and plantar pressure can be reliably measured in PsA patients using
