Keywords: Static Stability | Dynamic Stability | Shoe Heel | Young Women | Repeated Measures

Background and Aim: Wearing high-heeled shoes increases the height of the center of gravity and takes the line of gravity away from the center of the base of support. This may result in the loss of body balance. In this study the effect of 3 heel heights on the static and dynamic postural stability in healthy young women was investigated.Materials and Methods: In this cross-over quasi-experimental study with repeated measures, three dynamic indices of anteroposterior, mediolateral, and overall stability were determined using Biodex stabilometer and static stability using a modified CTSIB test. The measurements were made at 4 conditions of the feet, i. e., barefoot, and wearing shoes with a heel height of 3, 5, or 7 centimeters.Results: The mean static stability index in the barefoot condition was significantly different from that in any the 3 conditions of wearing heels. With the eyes closed, the most unstable condition was in the case of the 7-cm heel, which caused also the most unstable dynamic condition; the differences were all statistically significant.Conclusion: The findings indicate that postural instability increases with increases in the height of shoe heels. On the whole, considering both the static and dynamic stability, the 3-cm heel can be recommended as the optimum-height heel.
