background: manual material handling is one of the major health and safety hazards in industry. this study aims to assess the lifting tasks, before and after intervention using niosh lifting equation and manual handling assessment charts (mac). methods: this interventional study was performed in 2011 in a tile manufacturing industry in hamadan, located in the west of iran. the prevalence of mus...

background: low back pain caused by work, ranked the second after cardiovascular diseases, are among the most common reasons of patients’ referral to the physicians in iran. this study aimed to determine the changes in back compressive force when measuring maximum acceptable weight of lift in iranian male students. methods: this experimental study was conducted in 2015 on 15 young male students...

BACKGROUND AND AIMS  Non-lifting large laterally spreading colorectal lesions (LSLs) are challenging to resect endoscopically and often necessitate surgery. A safe, simple technique to treat non-lifting LSLs endoscopically with robust long-term outcomes has not been described. METHODS  In this single-center prospective observational study of consecutive patients referred for endoscopic mucosa...

Explanations for the ineffectiveness of lifting training often focus on the nature of the workplace. However, the process through which workers select a lifting method may contain priorities based on energy expenditure, unique anthropometry, lifting experience, personality profile or other characteristics of the individual worker. This empirical investigation studied the lifting technique selec...

We explore the lifting question in the context of cut-generating functions. Most of the prior literature on lifting for cut-generating functions focuses on which cut-generating functions have the unique lifting property. Here we develop a general theory for understanding how to do lifting for cut-generating functions which do not have the unique lifting property.

The study documented three-dimensional spinal loading during lifting from an industrial bin. Two lifting styles and two bin design factors were examined in Phase I. The lifting style measures in Phase I were one hand versus two hand and standing on one foot versus two feet. The bin design variables were region of load in the bin and bin height. The Phase II study examined one-handed lifting sty...

Two-person or team lifting is a popular method for handling materials under awkward or heavy lifting conditions. While many guidelines and standards address safe lifting limits for individual lifting, there are no such limits for team lifting, and these lifts are poorly understood. The literature associated with team lifting offers some interesting paradoxes. Many studies have indicated that pe...
