摘要: Abstract The objective of this work was to develop a method simulate single-limb ground contact events, which may be applied study musculoskeletal injuries associated with such movements. To achieve objective, three-dimensional model developed consisting the equations motion for system, and models muscle force generation elements. An optimization framework weighted least-squares function were presented that generated stimulation patterns optimally reproduced subject-specific movement data. Experimental data collected from single subject provide initial conditions simulation tracking optimization. As an example application, stance phase running generated. results showed average difference between subject's reaction joint angle less than two inter-trial standard deviations. Fur...
