introduction: ovako working posture analyzing system (owas) is a method for evaluating postural load during work. the owas method is based on a simple and systematic classification of work postures combined with observations of work tasks. the aim of this study was the assessment of various postures during the work in iron and steel industry, navard ahwas, using owas method. materials and metho...

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,...

BACKGROUND The evaluation of foot posture in a clinical setting is useful to screen for potential injury, however disagreement remains as to which method has the greatest clinical utility. An inexpensive and widely available imaging system, the Microsoft Kinect™, may possess the characteristics to objectively evaluate static foot posture in a clinical setting with high accuracy. The aim of this...

This paper describes ongoing work within the Light Water Reactor Sustainability pathway at Idaho National Laboratory (INL) to optimize security and cost of nuclear power plants. It introduces dynamic risk assessment tool developed INL, Event Modeling Risk Assessment using Linked Diagrams (EMRALD). EMRALD is leveraged posture a plant by integrating force-on-force (FOF) simulations operator mitig...

This paper presents our work on relationship of evaluation results between virtual environment (VE) and realistic environment (RE) for assembling tasks. Evaluation results consist of subjective results (BPD and RPE) and objective results (posture and physical performance). Same tasks were performed with same experimental configurations and evaluation results were measured in RE and VE respectiv...

This paper presents the preliminary results of a novel rehabilitation therapy for cervical and trunk control of children with cerebral palsy (CP). The therapy is based on the use of an inertial sensor that will be used to control a set of serious videogames with movements of the head. Ten users with CP participated in the study, in the experimental and control groups. Ten sessions of therapy pr...

The postures of wheelchair users can reveal their sitting habit, mood, and even predict health risks such as pressure ulcers or lower back pain. Mining the hidden information of the postures can reveal their wellness and general health conditions. In this paper, a cushion-based posture recognition system is used to process pressure sensor signals for the detection of user's posture in the wheel...

Background & Aims of the Study: Musculoskeletal disorders (MSDs) are part of the main occupational diseases in the workplace. Occupations such as hairdressers are exposed to multiple risk factors of these problems. The study was conducted to assess MSDs and posture analysis among female hairdressers in Tehran, 2015. Materials and Methods: I...

Validated injury criteria are essential when developing restraints for AIS 1 neck injuries that should protect occupants in different crash situations. Such criteria have been proposed and attempts have been made to validate/falsify these. However, no criterion has to date been fully validated. The objective of this study was to evaluate the influence of seat geometry and seating posture on NIC...
