OBJECTIVE To evaluate if chronic low back pain patients perform manual material handling tasks differently from control subjects. DESIGN Comparative study using a repeated measures design. BACKGROUND No study evaluated the lifting technique of back pain patients relative to control subjects during free style lifting and lowering tasks. Previous findings suggest that lowering would be more h...
This article presents the results of evaluations mechanical stresses associated with performance manual lifting tasks loads and those operators must endure in their workplaces, considering these most recurrent cases positions. study is based on a static analysis certainspecific positions human body, transmission forces through musculoskeletal structure, generation efforts at critical points bod...
Adopting appropriate postures during manual materialhandling tasks is the key to reducing human joint injuries. Although much experimentation has been conducted in an effort to model lifting, such an approach is not general enough to consider all potential scenarios in material handling. Thus, in this paper an optimization-based motion prediction method is used to simulate realistic lifting pos...
In such an aged society, various health issues occur in caregivers in nursing homes. Particularly in female caregivers, high blood pressure (Hosono et al., 2009) and coronary heart disease (Lee et al., 2003) have been reported to be at high risk. Additionally, caregivers have high prevalence rates of low back pain (LBP) and a high incidence of worker’s compensation claims for back injuries (Deh...
Background and Aim: Casting workers are facing with ergonomics hazards such as overload in Manual Material Handling (MMH) tasks which expose them to risk of work-related musculoskeletal disorders (WMSDs). There are several methods to determine acceptable weight among which, Snook table is one of the oldest one. The aim of the study was to assess prevalence of WMSDs and to investigate MMH task...
Ensuring glenohumeral stability during repetitive lifting tasks is a key factor to reduce the risk of shoulder injuries. Nevertheless, the literature reveals some lack concerning the assessment of the muscles that ensure glenohumeral stability during specific lifting tasks. Therefore, the purpose of this study was to assess the stabilization function of shoulder muscles during a lifting task. K...
