The Relationship of Height-Length Ratio of Foot and Resting Calcaneal Stance Position

ABSTRACT

OBJECTIVE: The purpose of this study was to know the correlation between resting calcaneal stance position (RCSP) and height-length (H/L) ratio of foot. METHOD: Both feet of 173 persons who visited the Department of Rehabilitation Medicine, Chungnam National University Hospital were included in the study. Their mean age was 23.6 years old. H/L ratio, RCSP and navicular angle of 346 feet were measured. All people were divided into 3 groups, such as, normal foot (-2degrees2degrees) according to the angle of RCSP. And the relationship between RCSP and H/L ratio were evaluated. Independent T-test, ANOVA and Pearson correlation of SPSS was used for statistical data processing. RESULTS: The mean H/L ratio of rear foot valgus was 0.2206, noraml foot 0.2440 and rearfoot varus 0.2625. H/L ratio and navicular angle showed significant increase in each RCSP groups in order of rear foot angle. CONCLUSION: H/L ratio and RCSP showed strong positive correlation and the value of H/L ratio in normal group was 0.2440+/-0.0114 (Mean+/-S.D.). H/L ratio is easily acceptable parameter in human mechanics or orthotic field of rehabilitation.
