Title: Creating Simulations with Real World Data - A Case Study of Obese Locomotion Biomechanics
Speaker: Zachery Lerner, Colorado State University
Time: Thursday, November 1, 2012 at 9:30 a.m. PST


This webinar will discuss the changes that can (and should) be made to a generic musculoskeletal model in order to more accurately represent the subject being studied and improve confidence in simulation results. Investigation of obese locomotion biomechanics will serve as a case study and motivating example demonstrating how to:
  • Transform your experimental data into the OpenSim coordinate system
  • Use digital markers to augment your experimental data
  • Update model parameters
  • Incorporate electromyography (EMG) data into your simulations as controls constraints to improve accuracy

Intended Audience

The intended audience for this webinar is anyone who:
  • Has a basic but limited understanding of OpenSim/Musculoskeletal modeling
  • May be unsure how to proceed after data collection
  • Is interested in modifying the generic models and setup files for their own research topic
  • Is stuck at a particular point along their simulation pipeline

Presenter Biography

Zachery Lerner is a doctoral student in the School of Biomedical Engineering at Colorado State University conducting research in Dr. Ray Browning's Physical Activity Lab. One element of his biomechanics-related research involves using musculoskeletal modeling as a predictive tool to analyze locomotion, to validate the benefits of proper exercise prescription, and to assist in the design of movement aiding/joint-unloading devices. He received a BSE in Mechanical Engineering from Northern Arizona University in 2010. Zach is also an avid rock climber and member of the US Climbing team.
