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 (⁣2^o≤RCSP≤2^o), rear foot valgus (RCSP＜⁣2^o) and rear foot varus (RCSP＞2^o) 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. (J Korean Acad Rehab Med 2002; 26: 591-597)
