background: musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. poor posture is the most important risk factor for work-related musculoskeletal symptoms. this study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...

UNLABELLED This study investigated the effectiveness of a workstation ergonomic intervention for work-related posture and low back pain (LBP) in Video Display Terminal (VDT) workers. 100 VDT workers were selected to receive the ergonomic intervention, whereas 100 were assigned to a control group. The two groups were then crossed-over after 30 months from baseline. Follow-ups were repeated at 5,...

With the increasing of computer capabilities, Computer aided ergonomics (CAE) offers new possibilities to integrate conventional ergonomic knowledge and to develop new methods into the work design process. As mentioned in [1], different approaches have been developed to enhance the efficiency of the ergonomic evaluation. Ergonomic expert systems, ergonomic oriented information systems, numerica...

This paper evaluates the effect of ergonomic factors on task performance and trainee posture during laparoscopic surgery training. Twenty subjects without laparoscopic experience were allotted into 2 groups. Group 1 was trained under the optimal ergonomic simulation setting according to current ergonomic guidelines (Condition A). Group 2 was trained under non-optimal ergonomic simulation settin...

Tracheal intubation is an important procedure in anesthesia and emergency medicine. The standard intubation technique is direct laryngoscopy using a Macintosh blade; however, video laryngoscopy has become common and research has shown several advantages of video laryngoscopy over direct laryngoscopy. In the present study we investigated whether video laryngoscopy resulted in the intubating pers...

Introduction Dental practitioners are exposed to different occupational hazards during the course of their professional activity, such as physical, chemical, biological, ergonomic factors. The ergonomic hazards, caused by strained posture and prolonged repetitive movements, can induce musculoskeletal disorders. It occurs in 54-93% of dental professionals and involve the spine, shoulder and hand...

Test subjects are samples, field experiments at three percentiles namely 5th, 50th 90th percentile range Singapore. demographic parameters tes...

Since the ergonomic intervention process is currently a highly individual, knowledge-based process, the development of a methodical procedure for this process has a great potential in ergonomics of working postures. Thus, in this paper a concept to support the ergonomic intervention process aiming to improve awkward working postures is described. A comprehensive analysis of working postures was...
