What is Ground Reaction Force (GRF)? SCIENCE

WebGround reaction force (GRF) data were collected on twenty adult males during running stance to establish normative standards to aid in assessment of the gait of atypical runners. Subjects ran between 30 and 40 trials across a Kistler 0.6 X 0.9 m force platform at self-selected speeds ranging from 2. … WebThe ground reaction force (GRF) is initially located posterior to the ankle at initial contact, creating a plantarflexion moment. During the loading response, the plantarflexion moment continues at the ankle, and ankle dorsiflexors must resist this torque to prevent foot drop. During midstance, the GRF moves anteriorly, so a strong dorsiflexion ...
