“…Due to the low activation of lumbar muscles while sitting, load is absorbed by viscoelastic structures and transmitted directly to the spine, causing muscle contractions and/ or structural damage and consequent severe back pain (43). Nevertheless, controversy still exists regarding the impact of occupational sitting posture on back pain (17), since extremely high doses of exposure are supposedly needed to affect spinal structures (44).…”

“…71 Sitting results in reduced muscle activation that correlates with lumbar spine flexion. 136 Slouched, seated postures resulted in extensor muscles shutting off almost completely, a phenomenon called flexion relaxation. 41,48,136 It is likely that preserved spinal posture is achieved through finding an optimum balance of strength and flexibility of the joints.…”

The goal of this review is to discuss the mechanisms of postural degeneration, particularly the loss of lumbar lordosis commonly observed in the elderly in the context of evolution, mechanical, and biological studies of the human spine and to synthesize recent research findings to clinical management of postural malalignment. Lumbar lordosis is unique to the human spine and is necessary to facilitate our upright posture. However, decreased lumbar lordosis and increased thoracic kyphosis are hallmarks of an aging human spinal column. The unique upright posture and lordotic lumbar curvature of the human spine suggest that an understanding of the evolution of the human spinal column, and the unique anatomical features that support lumbar lordosis may provide insight into spine health and degeneration. Considering evolution of the skeleton in isolation from other scientific studies provides a limited picture for clinicians. The evolution and development of human lumbar lordosis highlight the interdependence of pelvic structure and lumbar lordosis. Studies of fossils of human lineage demonstrate a convergence on the degree of lumbar lordosis and the number of lumbar vertebrae in modern Homo sapiens. Evolution and spine mechanics research show that lumbar lordosis is dictated by pelvic incidence, spinal musculature, vertebral wedging, and disc health. The evolution, mechanics, and biology research all point to the importance of spinal posture and flexibility in supporting optimal health. However, surgical management of postural deformity has focused on restoring posture at the expense of flexibility. It is possible that the need for complex and costly spinal fixation can be eliminated by developing tools for early identification of patients at risk for postural deformities through patient history (genetics, mechanics, and environmental exposure) and tracking postural changes over time.

“…However, to reduce the high prevalence of musculoskeletal diseases in the sedentary work of engineers, these professionals should be instructed by the rehabilitation doctors on how to activate their lumbar muscles through breaks for walking and alternating office work with activities in standing position, since ergonomic chairs are not effective as long as the sitting position itself causes the atrophy of lumbar muscles [3].…”

Abstract. The present study analyzes the use of bioethical expertise of Romanian rehabilitation doctors working in a hospital for engineering professionals, the Romanian Railways Clinical Hospital Iasi. The knowledge of the specific legislation by the medical personnel, proper communication, shared decision making and the use of informed consent are essential for effective healthcare provided to engineers, a group of professionals with a great contribution to the development of rehabilitation robotics and medical technology.
