The present study aimed to identify changes during the gait stance and swing phases in some lower limb muscles. In addition, abdominal muscle was included due to its importance in dynamic trunk stability, and lack of studies on the subject. Here, we found that the use of high-heeled shoes elicited not only the increasing of the electrical activity from the muscles involved in the gait cycle, but also altered the temporal sequence of their recruitment. As practical applications, these changes may be strategies to maintain stability and minimize risks of falling, but they are often associated to diseases. Women that use high-heeled shoes for prolonged time must apply specific muscle exercises to minimize its long-term effects.展开更多

Substantial reductions in workplace high heel wear were found, whereby increasingly those who wear high heels regularly at work have freely chosen to do so, although certain issues of social expectations remain in certain sectors. Largely, freedom of choice has greatly increased in workplaces in line with increased public and employer awareness.? However, high heel wear has not substantially reduced in social settings, and progress has not been made with social expectation and explicit requirement to wear high heels at social events.展开更多
