Effects of high heeled shoes on limits of stability in young women
Vaniessa Dewi Hapsari,Shuping Xiong 대한인간공학회 2013 대한인간공학회 학술대회논문집 Vol.2013 No.5
High heeled shoes have been associated with the increase of the risk of falls. An experimental study on examining the effects of wearing high heeled shoes on stability limits was conducted. Seven young females participated in the Limit of stability (LOS) test in the NeuroCom PRO Balance Master System. Reaction time, movement velocity, endpoint excursions, maximum excursions and directional control obtained from the LOS test were used to determine the maximum distance a person can lean in a given direction without stepping or losing balance. The experimental results showed that endpoint excursions and maximum excursions, expressed as percentages of the limits of stability, decreased significantly while participants were standing in high heeled shoes. The results suggested that standing in high heeled shoes will lessen an individual’s ability to retain a postural control when their balance is destabilized outside area of control, thus decreasing dynamic balance ability.

<P>This study aimed to examine the effects of high heeled shoes (HHS) wearing experience and heel height on human standing balance and functional mobility. Thirty young and healthy females (ten experienced and twenty inexperienced HHS wearers) participated in a series of balance tests when they wore shoes of four different heel heights: 1cm (flat), 4cm (low), 7cm (medium) and 10cm (high). Experimental results show that regardless of the wearing experience, the heel elevation induces more effort from lower limb muscles (particularly calf muscles) and results in worse functional mobility starting at 7cm heel height. While the heel height increased to 10cm, the standing balance also becomes worse. Experienced HHS wearers do not show significantly better overall performance on standing balance and functional mobility than inexperienced controls, even though they have better directional control (76.8% vs. 74.4%) and larger maximum excursion (93.3% vs. 89.7%). To maintain standing balance, experienced wearers exert less effort on tibialis anterior, vastus lateralis and erector spinae muscles at the cost of more intensive effort from gastrocnemius medialis muscle. Practitioner summary: Many women wear high heeled shoes (HHS) to increase female attractiveness. This study shows that HHS induce more muscular effort and worse human standing balance and functional mobility, especially when heel height reaches 10cm. HHS wearing experience only provides certain advantages to wearers on limits of stability in terms of larger maximum excursion and better directional control.</P>
