manual material handling is identified as one of the musculoskeletal disorders risk factors. the aims of this study were to evaluate lifting activities by niosh equation and mac method and the correlation of these two methods. this cross-sectional study was conducted in a rubber industry. studied subjects were 136 male workers selected from various sections by proportional-to size sampling meth...

The most frequent and expensive cause category of compensable loss is manual material handling (MMH). Casting workers who handle oxygen (O2) cylinders manually are at risk for work-related musculoskeletal disorders (WMSDs). The aim of this study was to assess manual handling of O2 cylinders by casting workers and to implement ergonomic intervention to reduce the risk of musculoskeletal disorder...

The main objective of the study was to model the electromyographic (EMG) responses for 10 trunk muscles in manual-lifting tasks using the fuzzy relational rule network (FRRN). The FRRN utilized trunk-related variables, including sagittal and lateral trunk moments, pelvic tilt and pelvic rotation angles, and sagittal, lateral, and twist trunk angles as model inputs. The EMG data for model traini...

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by tw...

OBJECTIVE Most surgeons prefer to perform anterior abdominal wall lifting during abdominal entry to avoid damage to intestines or main vessels. Anterior abdominal wall lifting is assumed to prevent vital organ injuries by creating an adequate distance prior to entry into the peritoneal cavity. In this study, we compared the distance created for trocar entry into the peritoneal cavity with towel...
