• Reducing Low Back Pain and Disability in Mining
  9/1/2008 - Information Circulars
  This report provides managers, supervisors, and safety and health professionals with information on low back pain (LBP) and low back disability. It also provides the latest LBP research and describes methods to address the problem.
• The Effects of Operator Position, Pallet Orientation, and Palletizing Condition on Low Back Loads in Manual Bag Palletizing Operations
  5/1/2015 - Peer reviewed journal articles
  An article describing the biomechanical demands of different work layouts when performing manual palletizing of small bags, and evaluates the biomechanical stresses associated with different stacking techniques.
• Analysis of Applied Forces and Electromyography of Back and Shoulders Muscles When Performing A Simulated Hand Scaling Task
  5/1/2010 - Peer reviewed journal articles
  This article describes experiments simulating rib scaling from an elevated bucket to examine force generation and electromyographic responses using two types of scaling bars at five target heights ranging from floor level to 176 cm.
• A Comparison of Fatigue Failure Responses of Old Versus Middle-Aged Lumbar Motion Segments in Simulated Flexed Lifting
  8/1/2007 - Peer reviewed journal articles
  In this study, survival analysis techniques were used to compare fatigue failure responses of elderly motion segments to a middle-aged sample. This study also evaluates the influence of bone mineral content on cycles to failure.
• The Effects of Scaling Height and Scaling Bar Design on Applied Forces and Bilateral Muscle Activity of the Back and Shoulders
  10/1/2006 - Conference papers
  Hand scaling is a physically demanding job responsible for overexertion injuries in mining. This experiment studied rib scaling from an elevated bucket to examine force generation capabilities and electromyographic responses to a prying subtask.
• An Exploratory Study of Loading and Morphometric Factors Associated with Specific Failure Modes in Fatigue Testing of Lumbar Motion Segments
  3/1/2006 - Peer reviewed journal articles
  Thirty-six human lumbar motion segments were fatigue tested using spinal compressive and shear loads that simulated lifting a 9 kg weight in three torso flexion angles. Results indicated that stellate endplate fractures were associated with increased po...
• Effects of Posture on Dynamic Back Loading During a Cable Lifting Task
  4/1/2002 - Peer reviewed journal articles
  This study evaluated spinal loads associated with lifting and hanging heavy mining cable in a variety of postures.
• Biomechanical Modeling of Asymmetric Lifting Tasks in Constrained Lifting Postures
  10/1/1997 - Conference papers
  Twelve subjects participated in an investigation of the biomechanical stresses of asymmetric lifting in stooped and kneeling postures. Three factors were manipulated in this study: posture (stooped or kneeling), height of lift (35 or 70 cm), and weight ...
• Effects of Posture on Back Strength and Lifting Capacity
  9/1/1997 - Book chapters
  The Bureau of Mines performed a pilot study examining the effects of posture on back strength and Maximum Acceptable Weight of Lift on six healthy male subjects (M = 32 years + 4 SD).
• Trunk Extension Strength and Muscle Activity in Standing and Kneeling Postures
  8/1/1997 - Peer reviewed journal articles
  The study was conducted to determine whether the kneeling posture alters extension torque capabilities in isometric and isokinetic exercises as compared with standing. A split-pilot experimental design was used to evaluate the influence of posture, tru...
