The aim of this study was to evaluate the changes in electromyographic (EMG)
activity of the lower limb muscles, and hip, knee and ankle kinematics during
gait while wearing low- (4-cm) and high-heeled (10-cm) shoes in 31 young and 15
middle-aged adult women. We observed an increase in knee flexion and decrease in
ankle eversion associated with elevated heel heights suggesting that compensatory
mechanisms attenuating ground reaction forces may be compromised during gait with
higher-heeled shoes. Additionally, we observed increased muscle activity during
high-heeled gait that may exacerbate muscle fatigue. Collectively, these findings
suggest that permanent wearing of heeled footwear could contribute to muscle
overuse and repetitive strain injuries.
