INTRODUCTION
The purpose of this study was to analyze the correlationship between COP(X)pathway & GRF(Fz) according to shoe's heel heights & bag weights during the gait of obese women.
METHOD
Participants selected as subject consist of young women(n=5) in 20's age(height: 167.64±1.69cm, age: 22.20±1.78yrs, body mass: 63.30±16.24kg, foot length: 23.73±0.96cm, foot width: 8.80±0.69cm), divided into 4 bag weights(0kg, 1.5kg, 3kg, 5kg) and walked with 2 types of shoe's high- heel(0cm, 9cm). A force-plate was used to collect GRF(AMTI OR6-7) data at a sampling rate of 1000Hz, and analyzed variables during gait were GRF(Y, Z) and COP(X) during gait.
RESULT
The horizontal shear of GRF were not statistically significant during gait(p>.05). But the vertical GRF showed the relative higher according to increase of bag weights and in particularly 9cm shoe's heel(p<.05). The correlationship between COP(X) and GRF(Fz), 0cm walking was showed significant difference in pathway of COP(X) in normal walking and 9cm shoe‘s heel showed linear relationship in pathway during gait.
CONCLUSION
Considering the results, obesity can particularly affect musculoskeletal function of the lower extremity to accelerate or decelerate gait motion and kept gait balancing. |
