To improve ergonomic recommendations and decrease work-related musculoskeletal disorders, thorough documentation of full-body, joint loading topography during occupational tasks is needed. Therefore, the purpose this study was to document full-body internal in terms estimated contact forces tasks. In addition, also compared proxies (e.g., external moments) commonly used assess injury risk 3D mo...

Most current applications of digital human figure models for ergonomic assessments of manual tasks focus on the analysis of a static posture. Tools available for static analysis include joint-specific strength, calculation of joint moments, balance maintenance capability, and lowback compression or shear force estimates. Yet, for many tasks, the inertial loads due to acceleration of body segmen...

Previous research proposed a method using interpolation of the joint angles in key frames extracted from a field-survey video to estimate the dynamic L5/S1 joint loading for symmetric lifting tasks. The advantage of this method is that there is no need to use unwieldy equipment for capturing full body movement for the lifting tasks. The current research extends this method to asymmetric lifting...

The Ergonomic tridimensional analysis (ETdA) was developed to be used as an auxiliary tool on the ergonomic intervention. It was specially designed for commercial areas with free circulation of people. Due to that, the client, the third ETdA dimension, becomes an important element and their opinions relevant in the ergonomic analysis. The remains two ETdA dimensions, professionals and analyst, ...

The paper describes the application of a simulation based ergonomic evaluation. Within a pilot project, the algorithms of the screening method of the European Assembly Worksheet were transferred into an existing digital human model. Movement data was recorded with an especially developed hybrid Motion Capturing system. A prototype of the system was built and is currently being tested at the Vol...

In this paper we present the idea of ergonomic instruments: musical devices that focus on minimising the learning curve of musicians by mapping inherent musical actions to the creation of music. We situate ergonomic instruments in the context of existing relevant work, and then discuss a new methodology towards the development of musical instruments including exploration of a musical goal which...

Objectives: The purpose of this study was for evaluation of relationship between hand function and age, sex by Jebson Taylor Test.This study determined whether age might be a factor when associated with sex. Methods: In this study Jebson Taylor was evaluated on hand in 180 normal males and females (0.50% male, 0.50% female) in each of the following 7 subtest in 3 age groups: (15-25), (35-45)...

AIMS To evaluate the effectiveness of an intensive educational and low-tech ergonomic intervention programme aimed at reducing low back pain (LBP) among home care nurses and nurses' aids. METHODS In 1999, 345 home care nurses and nurses' aids in four Danish municipalities were studied. Participants in two municipalities constituted the intervention group and participants in the other two serv...
