The objective of this study is to identify and describe the altered work distribution of the lower extremity muscles while walking in high-heeled shoes (HHS). Amount of work was calculated by using the power values which were obtained by using a three dimensional computerized gait analysis system during walking of the 17 healthy female subjects in standardized high heeled shoes (HHS) and in standardized low heeled shoes (LHS). Results of this study revealed a statistically significant decrease in the A1 and A2 phases of the ankle plantar flexor work, however, a statistically significant increase was detected in the H3 phase of the concentric hip flexor work. In conclusion, the findings of this study indicate that the use of high heeled shoes alter lower extremity kinetic functions and work distribution. It should be emphasised that, the potential role of foot posture in contributing to musculoskeletal disorders needs to be considered when evaluating pain compalints or prescribing shoes, insoles, lifts and surgical treatments.
