Abstract

|
|
Purpose: The purpose of this study is to determine the effects of high heeled shoes on the static balance and
EMG activity of lower extremity muscles.
Methods: Twenty subjects were composed of control group(wearing low-heeled shoes) and experimental
group(wearing high-heeled shoes). Two groups participated in bearfoot standing and measured static balance and EMG activity of lower extremity muscles. Balance Performance Monitor(BPM) was used to measure the static balance and FlexComp InfinitiTM was used to measure the EMG activity of lower extremity muscles.
Results: In static balance, sway area and path of experimental group was significantly larger than control
group(p<0.05). And sway velocity of experimental group was significantly faster than control group(p<0.05). They means static balance of experimental group was significantly lower than control group(p<0.05). In EMG activity, L5 paraspinalis and biceps femoris of experimental group was significantly more increased than that of control group(p<0.05).
Conclusion: The long-time experience in wearing high heeled shoes may have caused change in static balance
and EMG activity of lower extremity muscles.
