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.
-
9/1/2010 - Conference papersThis study assessed the difference between free cadence walking versus stoopwalking (under a 1.2-m ceiling), four-point crawling (hands and knees), and two-point crawling (knees only), both with and without kneepads.
-
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.
-
2/1/2010 - Information CircularsThis report describes a study of operator movement relative to the motion of a roof bolting machine boom arm. This work was aimed at reducing the risk of injury to underground coal mine workers from moving machinery.
-
1/1/2010 - Peer reviewed journal articlesThis study gathered data to support earlier NIOSH findings that specialized padded seats are improved designs for coal mine shuttle cars. Study results have potential application to vehicles used in surface mining, construction, and agriculture.
-
10/1/2009 - Conference papersBy surveying experienced equipment operators about visual cues, researchers developed a method to gather data on the needs and practices of machine operators while controlling the machine and the reasons for needing particular operational cues.
-
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.
-
9/1/2008 - Peer reviewed journal articlesThe objectives of this study by NIOSH were to assess driver whole-body vibration (WBV) exposures and recommend interventions to reduce the risk of back-related injuries, particularly relative to vehicle jarring/jolting.
