Locomotion in restricted space: kinematic and electromyographic analysis of stoopwalking and crawlingSean Gallagher
National Institute for Occupational Safety and Health, Office of Mine Safety and Health Research, Pittsburgh, PA 15236 0070, USA
Gait Posture 33:71-6. 2011..05); however, subjects complained of discomfort without kneepads (especially in two-point crawling). Results of this study have implications for work performed in underground coal mines, as well as emergency or evacuation considerations...- Electromyography of the thigh muscles during lifting tasks in kneeling and squatting posturesSean Gallagher
National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, Pittsburgh, PA, USA
Ergonomics 54:91-102. 2011..This paper examines the EMG responses of knee extensors/flexors to lifting in these postures, discusses the impact of posture and kneepads on muscle recruitment and explores the implications for work in such postures... 
A comparison of fatigue failure responses of old versus middle-aged lumbar motion segments in simulated flexed liftingSean Gallagher
NIOSH Pittsburgh Research Laboratory, Pittsburgh, PA 15236 0070, USA
Spine (Phila Pa 1976) 32:1832-9. 2007..Survival analysis techniques were used to compare the fatigue failure responses of elderly motion segments to a middle-aged sample...- An exploratory study of loading and morphometric factors associated with specific failure modes in fatigue testing of lumbar motion segmentsSean Gallagher
National Institute for Occupational Safety and Health, Mining Injury Prevention Branch, P O Box 18070, Pittsburgh, PA 15236 0070, USA
Clin Biomech (Bristol, Avon) 21:228-34. 2006..There is currently little information regarding factors associated with specific modes of motion segment failure using a fatigue failure model... - Torso flexion loads and the fatigue failure of human lumbosacral motion segmentsSean Gallagher
National Institute for Occupational Safety and Health, Pittsburgh, PA 15236 0070, USA
Spine (Phila Pa 1976) 30:2265-73. 2005..5 degrees, and 45 degrees), and lumbosacral motion segments were cyclically loaded using these loads until failure or to a maximum of 10,020 cycles... - Effects of posture on dynamic back loading during a cable lifting taskSean Gallagher
National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, PA 15236 0070, USA
Ergonomics 45:380-98. 2002..05). Despite the more selective nature of trunk EMG changes due to posture, the magnitude of changes in spinal loading was often quite dramatic. However, average compression values exceeded 3400 N for all cable lifting tasks... - Physical limitations and musculoskeletal complaints associated with work in unusual or restricted postures: a literature reviewSean Gallagher

J Safety Res 36:51-61. 2005..g., underground miners, aircraft baggage handlers, plumbers, agricultural workers, mechanics, and others) are often required to adopt postures such as kneeling, stooping, squatting, or lying down for significant periods of the workday... - An analysis of injury claims from low-seam coal minesSean Gallagher
National Institute for Occupational Safety and Health, Mining Injury Prevention Branch, Pittsburgh, PA 15236 0070, USA
J Safety Res 40:233-7. 2009..The restricted workspace present in low-seam coal mines forces workers to adopt awkward working postures (kneeling and stooping), which place high physical demands on the knee and lower back... - Analysis of applied forces and electromyography of back and shoulders muscles when performing a simulated hand scaling taskWilliam Porter
Pittsburgh Research Laboratory, National Institute for Occupational Safety and Health, 626 Cochrans Mill Road, Pittsburgh, PA 15236, USA
Appl Ergon 41:411-6. 2010..Results of these studies suggest that miners scale points on the rock face that are below their knees, and reposition the bucket as often as necessary to do so... - Visual performance for trip hazard detection when using incandescent and led miner cap lampsJohn J Sammarco
