• Forces and Moments on the Knee During Kneeling and Squatting
  8/1/2011 - Peer reviewed journal articles
  For 10 subjects in four postures, euler angle decomposition and inverse dynamics were used to determine the knee angles, the net forces, and the moments applied to the tibia during kneeling and squatting with and without kneepads.

• Pressure Distribution on the Anatomic Landmarks of the Knee and the Effect of Kneepads
  12/1/2010 - Peer reviewed journal articles
  This study examines stress transmitted to anatomic landmarks of the knee (patella, combined patella tendon, and tibial tubercle) while in static kneeling postures without kneepads and while wearing two kneepads commonly used in the mining industry.
• External L5-S1 Joint Moments When Lifting Wire Mesh Screen Used to Prevent Rock Falls in Underground Mines
  9/1/2009 - Peer reviewed journal articles
  This study uses biomechanical modeling to estimate external moments about L5-S1 for sixteen lifting tasks, using two sizes of wire mesh screens, and presents recommendations to reduce spine loading.
