Eleven young women (Age: 22.14 ± 2.93yrs, Height: 1.63 ± 0.04 m, Weight: 52.44 ± 6.94 kg, BMI: 19.85 ± 2.99 kg/m 2 ) participated in the study. The age of the young women was within the age range (20 to 29 years old) that the highest rate of injuries due to the use of high heel shoes is reported ( 34.2% of cases from 2002 to 2012 [15], and 33.4% of cases from 2006 to 2010 [16]). Their anthropometric characteristics Abstract Objectives: The studies examining the high-heeled shoes effect use the

This study aimed to examine the effect of high-heeled shoes in the upright and the leaning stance. Methods: The trajectory of the center of pressure (COP) was recorded (forceplate Kistler-9286AA, sampling at 100 Hz, software Kistler BioWare ® -2812A1, v.3.2.6) in 11 young women (22.14 ± 2.93 years, moderate users of high-heeled shoes) in the quiet upright and the leaning stance (forward, backward, rightward, leftward rigid body leaning). The participants were tested barefoot (BF) and with two high-heeled shoes (heel height-HH: 6.5 cm and 11 cm). In the upright stance, the anterior-posterior and the medial-lateral COP path (cm) and COP range (cm), respectively, were determined. In the leaning stance, the COP displacement (cm) and the COP range of stability (% of BS length and % of BS width) were determined. In each stance, a repeated measures ANOVA followed by HH pairwise comparisons were used for statistics (p ≤ 0.05, SPSS 22.0). Main outcomes and results: In the upright stance, the COP path was significantly increased (p ≤ 0.05) in the high-heeled shoes compared to BF, as well as when the HH was increased. The COP range was not significantly altered (p > 0.05). In the leaning stance, both the COP displacement and the COP range of stability were significantly altered (p ≤ 0.05), with a directional sensitivity of the significant alterations in the COP range of stability. Conclusions: The high-heeled shoes induce COP alterations which indicate a worsening of postural control in both the upright and the leaning stance, with a directional sensitivity in the leaning stance. Thus, the body positions that challenge postural control more than the typical upright stance should be also included in relevant studies.
