Abstract
We explored the tibiofemoral contact forces and the relative contributions of muscles and external loads to those contact forces during various gait tasks. Second, we assessed the relationships between external gait measures and contact forces. A calibrated electromyography-driven neuromusculoskeletal model estimated the tibiofemoral contact forces during walking (1.44 ± 0.22 m s-1), running (4.38 ± 0.42 m s-1) and sidestepping (3.58 ± 0.50 m s-1) in healthy adults (n = 60, 27.3 ± 5.4 years, 1.75 ± 0.11 m, and 69.8 ± 14.0 kg). Contact forces increased from walking (~1-2.8 BW) to running (~3-8 BW), sidestepping had largest maximum total (8.47 ± 1.57 BW) and lateral contact forces (4.3 ± 1.05 ..
