Purpose: The purpose of this collaborative study with Ohio State University, Wright State University, and the Naval Medical Research Unit-Dayton was to determine biological and biomechanical biomarkers to predict susceptibility to motion
sickness and low back disorders in naval aircrew. Low back function, spinal loading, postural stability, gait function, and gene expressions were measured before and after motion sickness exposure.
Comparison of postural stability results before and after exposure to motion sickness

Purpose: This investigation addressed acute JP 8 jet fuel exposure in a healthy workforce to determine if an effect is evident in their postural balance measurements. Postural balance of Air Force mechanics was measured with
a force platform before and after acute exposure to JP-8.
Effect of chronic exposure to JP-8 on ability to maintain a safe postural balance on uneven (foam) surface.

Purpose: This study was designed to quantify postural instability of low seam miners while carrying out mine-related tasks under exposure to individual and combined risk factors of environmental lighting, surface condition, and footwear
Hammer-Walk in Simulated Low Seam MineLow seam miner walking with 20 lb bag on his back in steel-toed and in rubber boots with a hammer for balance support.

Purpose: This study was designed to investigate the impact of workplace-related risk factors on postural balance of 95 industrial workers in three age groups, i.e. 45-54 years, 55-64 years, and 65-75 years.
Risk factors investigated were task-type performed (static & dynamic), environmental lighting, standing/walking surface slipperiness, inclinations, and footwear hardness.
Measuring dynamic balance while walking up and down a slippery ramp.
