Table 5 Inertial and reaction forces

From: A finite element model of the lower limb during stance phase of gait cycle including the muscle forces

  1. The soft spring forces and the inertial forces are considered negligible compared to the hip joint reaction forces. The relative difference was estimated by considering the magnitude of the hip joint reaction forces from the RB model as reference value
