• Locomotion in Restricted space: Kinematic and Electromyographic Analysis of Stoopwalking and Crawling
  1/1/2011 - Peer reviewed journal articles
  Nine 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).
• Electromyography of the Thigh Muscles during Lifting Tasks in Kneeling and Squatting Postures
  1/1/2011 - Peer reviewed journal articles
  This 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.
• 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.
• 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...
• 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...
• 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.
