8/1/2011 - Peer reviewed journal articlesFor 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.
-
12/1/2010 - Peer reviewed journal articlesThis 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.
-
3/1/2012 - Peer reviewed journal articlesThe objective of this study was to determine low-seam mine worker exposure to various postures as they pertain to job classifications and job tasks.
-
1/1/2011 - Peer reviewed journal articlesNine participants, six males and three females, participated in a study examining kinematic and electromyographic (EMG) responses to natural cadence stoopwalking, four-point crawling (all fours), and two-point crawling (knees only).
-
1/1/2011 - Peer reviewed journal articlesThis paper examines the EMG responses of knee extensors/flexors to lifting in kneeling or squatting postures and discusses the impact of posture and kneepads on muscle recruitment and explores the implications for work in such postures.
-
8/1/2010 - Conference papersNIOSH investigated muscle activity, forces, stresses, and moments at the knee (with and without kneepads) while subjects assumed various postures, including kneeling in full flexion, kneeling at 90° of flexion, kneeling on one knee, and squatting.
-
8/1/2009 - Conference papersThe pressure applied to the patella and combined PT and TT was determined for postures associated with low-seam mining.
-
8/1/2009 - Conference papersIn this study thigh-calf and heel-gluteus contact forces were quantified to on the externally applied flexion moment in high flexion.
-
2/1/2006 - Book chaptersExperience has shown that many ergonomic techniques used to analyze or design standing or sitting work stations often do not adapt well to situations where a restricted posture is adopted. However, recent years have seen an increase in research examinin...

3/1/2001 - Peer reviewed journal articlesCoal miners often handle heavy electrical power cables, weighing up to 10 kg per meter. These cables are manually lifted and attached to the mine roof to prevent damage from mobile underground equipment.
