Brief Description

How the central nervous system coordinates muscles during normal and abnormal movement to achieve a behavioral task is an open question and computer simulation is a vital tool for providing answers. We have been developing and applying a computational framework, in combination with experiments, to begin uncovering unrecognized mechanisms of neuromuscular control, dynamics, and function for behavioral tasks. The framework provides an interface between MATLAB/Simulink and the open-source neuromusculoskeletal simulation software OpenSim, enabling rapid model-based design of control algorithms for the neuromusculoskeletal system. In this webinar, we will cover key concepts of this framework and highlight our research investigating coordinated and uncoordinated movements. This framework may be used to discover new movements as treatments and predict outcomes using pre-treatment data on an individual basis.

Who Should Attend?

This webinar would benefit the following types of participants:

  • Computational biomechanists making the transition from inverse dynamics analyses to forward dynamic simulations
  • Anyone interested in developing software elements for neuromuscular control
  • MATLAB/Simulink users that would like an OpenSim model block as their biomechanics system
  • OpenSim users that would like to create muscle excitations and/or task-level inputs for closed-loop control using MATLAB/Simulink

Specific Benefits to Participants

  • A better understanding of why OpenSim and MATLAB/Simulink are both important for controlling your simulations
  • A conceptual overview of interfacing OpenSim with MATLAB/Simulink for closed-loop control
  • Explanation of key concepts, including the MATLAB S-function, Simulink block specifics, forward dynamics, and feedback control
  • Interactive discussion of research using musculoskeletal modeling, biologically inspired control systems, and forward dynamic simulation to advance the study of human movement control and treatment outcome prediction
