Biomechanical analysis of peak and cumulative spinal loads during simulated patient-handling activities: a substudy of a randomized controlled trial to prevent lift and transfer injury of health care workers

An Examination of Shoulder Postures and Moments of Force Among Different Skill Levels in the Wool Harvesting Industry

“…It is well known in the industry how these skill levels differ from a quality and tally perspective, such that open class shearers and wool handlers produce higher quality fleeces and wool classifications, and have a higher daily tally; however, the current study was the first to examine the effect of skill on biomechanical variables. Previous work examining the biomechanical differences in trained versus untrained manual material handlers found that trained individuals were exposed to lower (spinal) loading [6,7,8], while the current study did not find consistent reductions in shoulder moment magnitude in the elite shearers and wool handlers. Rather, it found that certain shoulder moments were higher in the open class workers, while other moments were lower.…”

“…These occupational-based studies explored the effect of skill on low back loading, in particular during manual material handling [6,7,8]. These studies found that untrained, or lower skilled individuals, are exposed to higher spinal loading during lifting when compared to experienced workers.…”

Work-related musculoskeletal risks associated with nurses and nursing assistants handling overweight and obese patients: A literature review

“…Researchers [20][21][22][23] examined different aspects of patient handling and lifting including the loads and how they act on the lumbar spine. Biomechanists have established that compression and shear loads on the lumbar spine during patient handling are high [19].…”

Risk Assessment of Musculoskeletal Disorders Related to Patient Transfer Tasks Using the Direct Nurse Observation Instrument Method

“…Daynard was shown that nurses who were not compliant had higher peak spinal loading than those who were compliant (32). Therefore, using a safe work technique by nurses might lead to a reduced load to their musculoskeletal system.…”
