Do Industrial Back Belts Reduce Stress in Asymmetric Lifting?
نویسندگان
چکیده
The systemic effects of wearing an industrial back belt for a repetitive asymmetric lifting task between knee and waist height have been investigated. Belt wearing significantly reduced the average heart rate by 5.3 beats per minute, constituting 21% reduction of the metabolic cost due to the exercise. Back belt significantly reduced the average systolic blood pressures by 9 mm of Hg. For manual material handling activities that require mild torso flexion, back belt seem to produce a favorable effect.

Effectiveness and cost-effectiveness of employer-issued back belts in areas of high risk for back injury.
Back belts have gained popularity under the assumption that their use will reduce low back injuries and thereby decrease the costs. This study sought to examine that hypothesis. A retrospective survey instrument was administered to 1316 workers who perform lifting activities at Tinker Air Force Base, Midwest City, Oklahoma, to identify belt use, lifting requirements, injury, and treatment histo...
متن کاملEffect of Lifting Belts, Foot Movement, and Lift Asymmetry on Trunk Motions
Whether or not lifting belts protect workers from injury is a topic of considerable interest in industry. Not only is the protective effect uncertain, but the biomechanical basis for belt function is unclear. The objective of this study was to determine if lifting belts provide a means for controlling trunk motions during asymmetric material-handling tasks. We recruited 16 nursing personnel as ...
متن کاملStudy of low back pain intensity and disability index among manual material handling workers of a tile and ceramic industrial unit, Iran (2016)
Background: The revised National Institute for Occupational Safety and Health (NIOSH) lifting equation (RNLE) is commonly used for risk assessment of manual handling, and can estimate low back pain (LBP) biomechanical stressors of lifting and/or lowering of loads. The aim of this study was to evaluate manual material handling by using the RNLE, LBP, and LBP disability index (LBPDI) among worker...
متن کاملAn Evidence-Based Multidisciplinary Practice Guideline to Reduce the Workload due to Lifting for Preventing Work-Related Low Back Pain
We developed an evidence-based practice guideline to support occupational safety and health (OSH) professionals in assessing the risk due to lifting and in selecting effective preventive measures for low back pain (LBP) in the Netherlands. The guideline was developed at the request of the Dutch government by a project team of experts and OSH professionals in lifting and work-related LBP. The re...
متن کاملThe Effect of Back Belt on Maximum Displacement and Center of Pressure Velocity in Different Lifting Styles
Purpose: Mechanical loading is said to be an important factor in the development of low back pain (LBP). One of the main concerns in manual material handling (MMH) tasks is lifting loads, as this activity is present in most jobs. Despite the controversy about their effectiveness, belts are used in industry as either protective or assistive devices in manual load handling. The present inve...
