• Characteristics of Gait in Restricted Vertical Space Versus Unrestricted Walking
  9/1/2010 - Conference papers
  This 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.
• Mine Roof Bolting Machine Safety: Investigation of Roof Bolter Boom Swing Velocity
  2/1/2010 - Information Circulars
  This 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.
• Evaluation of Work Positions used by Continuous Miner Operators in Underground Coal Mines
  10/1/2009 - Conference papers
  By 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.
• Working in Unusual or Restricted Postures
  2/1/2006 - Book chapters
  Experience 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...
• Whole-Body Vibration and Postural Stress among Operators of Construction Equipment: A Literature Review
  7/1/2004 - Peer reviewed journal articles
  This review evaluates selected papers that have studied exposure to whole-body vibration and awkward posture among operators of mobile equipment.
• An Ergonomic Evaluation of Excavating Operations: A Pilot Study
  7/1/2001 - Peer reviewed journal articles
  The objective of this study was to systematically characterize the ergonomic hazards associated with excavating operations.
• 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 Lifting in Four Restricted Postures
  9/1/1997 - Conference papers
  The purpose of this study was to examine the lifting capacity of low-seam coal miners in four restricted postures (roof heights of 36", 40", 44", and 48"), investigate the associated metabolic costs, and to examine electromyographic (EMG) data from eigh...
• Lifting in Stooped and Kneeling Postures: Effects on Lifting Capacity, Metabolic Cost, and Electromyography of Eight Trunk Muscles
  11/1/1988 - Peer reviewed journal articles
  Results of this Bureau of Mines study indicate that it may be advisable to reduce the weight of materials that are handled repetitively in the kneeling posture.
