This paper discusses the possible causes of musculoskeletal pain in VDT workers and
outlines strategies to minimize it. The paper reviews workstation, chair, and keyboard …

The ability of the spine to carry load depends on the structural capacity of the vertebrae and
on the loading conditions that arise from activities of daily living or trauma. The ratio of the …

We studied the validity of predictions of compressive loads on the lumbar spine and
contraction forces in lumbar trunk muscles based on a biomechanical model. The …

A model of the lumbar back muscles was constructed incorporating 49 fascicles of the
lumbar erector spinae and multifidus. The attachment sites and sizes of fascicles were …

This study deals primarily with the stability of the base of the spine. The sacroiliac joints are
vulnerable to shear loading on account of their predominantly flat surfaces. This raises the …

A combined finite element and optimization approach to study the effects of muscles on the
biomechanics of the lumbar spine was initiated. Briefly, a three-dimensional, nonlinear, finite …

A biomechanical evaluation of the job-related stresses imposed upon a worker is a potential
means of reducing the high incidence rates of manual material handling injuries in industry …

Assessment of the effects of lifting on the low back has most frequently been done with the
aid of static models. Many lifting movements appear to have substantial inertial components …

Nos dias atuais, problemas posturais têm sido considerados um sério problema de saúde
pública, pois atingem uma alta incidência na população economicamente ativa …

Interviews were conducted with 303 men to determine aspects of work history and working
environment that are related to low-back pain. Respondents included no pain, moderate …
