Software, models, and data are provided below to help you generate and analyze simulations of landing. Various models are available to help meet your needs, including: 1. A generic landing model with muscles and ground contact geometry on each leg/foot 2. Models scaled to the subject used in this publication 3. Reduced models for exploring right-leg landing 4. Single-leg models with optimized stretch feedback controllers for landing 5. A library of models exploring varying levels of evertor/invertor co-activation or stretch reflexes. Simulation results for these each model variant are also provided.
