A dynamic biomechanical evaluation of lifting maximum acceptable loads.
A biomechanical evaluation of the job-related stresses imposed upon a worker is a potential means of reducing the high incidence rates of manual material handling injuries in industry. A biomechanical model consisting of seven rigid links joined at six articulations has been developed for this purpose. Using data from cinematographic analysis of lifting motions the model calculates: (1) body po...
متن کاملEffect of background music on maximum acceptable weight of manual lifting tasks.
This study used the psychophysical approach to investigate the impact of tempo and volume of background music on the maximum acceptable weight of lift (MAWL), heart rate (HR) and rating of perceived exertion (RPE) of participants engaged in lifting. Ten male college students participated in this study. They lifted a box from the floor, walked 1-2 steps as required, placed the box on a table and...
متن کاملAssociation between spinal loads and the psychophysical determination of maximum acceptable force during pushing tasks.
The objective of this study was to investigate potential associations between an individual's psychophysical maximum acceptable force (MAF) during pushing tasks and biomechanical tissue loads within the lumbar spine. Ten subjects (eight males, two females) pushed a cart with an unknown weight at one push every two minute for a distance of 3.9 m. Two independent variables were investigated, cart...
متن کاملAssessment of the adecuacy of KIM-LHC method in assessing the risk level based on biomechanical loads for manual lifting tasks: A laboratory study
Introduction: Manual Material handling includes activities in which pushing, pulling, lifting, lowering, carrying, and holding the load, the most common of which is lifting. This study aimed to evaluate the reliability of the KIM-LHC method to identify high-risk manual load lifting tasks. Material and Methods: This cross-sectional study was performed on healthy male workers with a history of m...
