Subject Specific Concurrent Simulation of Movement and Natural Knee Contacts Mechanics

Funding for this project was provided by the National Institutes of Health, National Institute of Arthritis and Musculoskeletal and Skin Diseases (Award # RAR061698B, PI: Guess)

This project combines custom muscle driven musculoskeletal models with subject specific geometries and gait data to predict patient specific loading on knee structures and tissues during ambulation. These tools provide greater understanding of knee biomechanics and soft tissue function and enable personalized intervention strategies aimed at modifying gait to reduce stress on knee cartilage.

Validation of Musculsokeletal Models with Instrumented Prosthetic

The purpose of this project is to validate the knee contact force predictions of our custom muscle driven musculoskeletal models using experimental data provided by the Grand Challenge Competition to Predict In Vivo Knee Loads. The experimental data includes knee loading from an instrumented total knee replacement along with motion capture, EMG, and ground reaction forces.

Comparison of Marker Based and Markerless Motion Capture Systems

Markerless motion capture systems have benefits over traditional marker-based motion capture for measuring human movement. The markerless systems decrease preparation time and allow more natural movement. But, studies reporting the accuracy and repeatability of these systems are rare. The purpose of this study is to compare joint motion calculated through a marker based system (Vicon MX-T40S), a markerless system (Organic Motion BioStage), and a portable markerless system (Kinect).

Power Generation during Standing Long Jump and Vertical Jump of Division I Collegiate Soccer Players

The purpose of this project is to measure and analyze power generation during jumping for Div I athletes.

Validity of the Mad Maxx Power Reading for Firing out of the Positional Stance for American Football Players

The speed and power of offensive and defensive lineman is key for the success of a football team. The ability to measure the change in abilities for a sports specific movement like firing off of the ball is crucial to understanding the effectiveness of the strength and conditioning program. The MAD MAXX (Just Better Sports by Shoot-A-Way - Upper Sandusky, OH) is essentially an immovable tackling dummy which purportedly measures the power of the athlete when driving off of the ball as well as their reaction time. It is unknown, however, how the power is measured and if the power reading is actually accurate at all. The purpose of this project is to validate power readings of the MAD MAXX.

Patient-Specific Rehabilitation in Knee Osteoarthritis

The long-term goal of this project is to develop more effective knee osteoarthritis rehabilitation programs tailored to the individual patient based on a clinical assessment panel designed to categorize the patient’s disease status (i.e., clusters). The Mizzou MAC’s role in this project is to quantify biomechanical variables of human motion for subject involved in this study.
