Abstract

The purpose of this study is to simulate and identify the muscle activation patterns in hip joints during a normal level walking and sit-to-stand task, before and after an implant. The muscle activation patterns for a task are computationally calculated using LifeMOD® software with inverse-forward dynamics method. Previous literature suggests that implants with trapezoidal crosssection area of proximal region in the femoral stem (TCSA) perform better than stand designs. Therefore, we simulated the effects of these two implants on the five muscles in the hip. A comparison between the results of the operated (right leg) and non-operated (left leg) suggests that the shape and mass of femoral stem influences the activation of these muscles. These findings may help in predicting muscle activation patterns for a given hip prosthesis, which may be helpful in designing future implants and for post surgical rehabilitation. © 2014 Society for Biomaterials and Artificial Organs - India.
