How walking speed influences muscle contributions to forward progression: implications for functional mobility in the elderly

Funding Agency: The Whitaker Foundation
Project Description: The goal of this project is to investigate how walking speed influences muscle contributions to forward progression, with a special emphasis on how deficits in various musculoskeletal properties impair walking performance in the elderly.
Collaborators: Dr. Ton van den Bogert, Cleveland Clinic Foundation; Dr. Steve Kautz, University of Florida and the Malcom Randall VA Medical Center

Induced acceleration analysis for rehabilitation

Funding Agency: The National Institutes of Health (SBIR grant to C-Motion, Inc)
Project Description: The purpose of this project was to develop models and analysis techniques for Visual3D to analyze human movement.
Collaborators: Dr. Scott Selbie at C-Motion; Tom Kepple at NIH; Dr. Kotaro Sasaki at UT Austin.

Biomechanical implant wear mechanisms during human locomotion

Funding Agency: The Whitaker Foundation and the Charles W. Tate & Judy Spence Tate Charitable Foundation
Project Description: The goal of this project is to integrate forward dynamic simulations with a detailed contact model to help identify orthopedic implant wear mechanisms during human locomotion.
Collaborators: Dr. Mike Bryant at UT Austin, Dr. Catherine Ambrose at the UT Health Science Center-Houston and Dr. Charles Layne at the University of Houston.

A theoretical analysis of chainring shape to improve cycling performance

Project Description: This project integrated a detailed musculoskeletal model and forward dynamics pedaling simulation and design optimization to determine the optimal chainring shape that improves maximal power output relative to a conventional circular chainring at different pedaling rates.
