What is Development and validation of a novel rating system for scoring standing foot posture: The Foot Posture Index about?

## Introduction: The limitations of clinical methods for appraising foot posture are well documented. a new measure, the foot posture index is proposed, and its development and validation described. ## Methods: A four-phase development process was used: (i) to derive a series of candidate measures, (ii) to define an appropriate scoring system, (iii) to evaluate the validity of components and modify the instrument as appropriate, and (iv) to investigate the predictive validity of the finalised instrument relative to static and dynamic kinematic models. methods included initial concurrent validation using rose's valgus index, determination of inter-item reliability, factor analysis, and benchmarking against three dimensional kinematic models derived from electromagnetic motion tracking of the lower limb. ## Results: Thirty-six candidate components were reduced to six in the final instrument. the draft version of the instrument predicted 59% of the variance in concurrent valgus index scores and demonstrated good inter item reliability (cronbach's alpha = 0.83). the relevant variables from the motion tracking lower limb model predicted 58-80% of the variance in the six components retai
