Ground reaction force in gait
WebDec 23, 2016 · Major forces involved in human locomotion are the ground reaction force (GRF) , joint reaction force (JRF), and muscle force (MF) . Force provided by a supporting horizontal surface is known as the … WebThe GRF profile during the gait cycle was obtained. Using the Davis protocol, the hip, knee, and ankle joint centers were calculated based on markers’ coordinates, regression equations, and anthropometric measurements. Similarly, spatial–temporal parameters, joint kinematics, and kinetics were obtained.
