A good work environment is important for the individual, for industry and for society. The work environment research has, predominantly, targeted identification of problems and the measurement of the size of these problems. Innovations to reduce the incidence of musculoskeletal disorder, MSD, have been introduced in different branches of industry, but with limited success. Few of the ergonomic ...

It has been suggested that interjoint coordination may serve to reduce joint stress and muscular demand and to maintain balance during dynamic lifting tasks, thus having implications for safe lifting practices. Before recommending the use of an on-body ergonomic aid, the Personal Lift-Assist Device (PLAD), it is important to determine any effects this device may have on interjoint coordination....

OBJECTIVES To quantify the variability in lifting motions, trunk moments, and spinal loads associated with repeated lifting exertions and to identify workplace factors that influence the biomechanical variability. DESIGN Measurement of trunk dynamics, moments and muscle activities were used as inputs into EMG assisted model of spinal loading. BACKGROUND Traditional biomechanical models assu...

OBJECTIVE To determine trunk muscle activity when lifting an object of greater weight than expected, which may contribute to the development of low back pain. DESIGN Electromyographic evaluation of trunk muscle activity. SETTING University of Tsukuba, Spine laboratory. PARTICIPANTS Eleven healthy men with a mean age of 24 (SD 2) years. INTERVENTIONS Trunk muscle activity was measured wh...

background and objectives: painting workshops are part of the woodwork (carpentry) industry in which despite advances in technology, the work force fulfills most of the roles in the production process. since such manual activities are often performed with awkward postures due to lack of workers’ awareness and inappropriate design of tools and working conditions, ergonomic assessment of work env...
