Anterior thoracic posture increases thoracolumbar disc loading

Abstract: In the absence of external forces, the largest contributor to intervertebral disc (IVD) loads and stresses is trunk muscular activity. The relationship between trunk posture, spine geometry, extensor muscle activity, and the loads and stresses acting on the IVD is not well understood. The objective of this study was to characterize changes in thoracolumbar disc loads and extensor muscle forces following anterior translation of the thoracic spine in the upright posture. Vertebral body geometries (C2 to S1) and … Show more

“…Since the barycentremetric study by Duval-Beaupere et al, 6 researchers have attempted to further study the impact of sagittal plane alignment on biomechanical loads and degenerative changes of the spine. 5,8,12,[17][18][19] Several methods have been developed to identify the location the center of gravity in the context of spine-related research. In 1992, Duval-Beaupere et al described a method 6 based on a gamma-ray scanner prototype that was combined with lateral radiography.…”

“…Prior musculoskeletal models have incorporated the thorax as a single rigid segment [2], have neglected the mechanical contribution of the ribs and sternum [2][3][4][5], or have lacked an anatomically realistic model of the rib cage [6], making them unsuitable for predicting thoracic skeletal and muscular loading. A few prior models included an articulated thoracic spine, but not the rib cage or the detailed thoracic musculature [3,5,[7][8][9]. In addition, these prior models were not validated against in vivo measures of spine and trunk muscle loading, and were only used to assess vertebral loading during a neutral standing posture.…”

“…Inappropriate or excessive lumbar extension by ICL produces pain due to greater disk loading, compressive force, and shearing force caused by an increased spinal curve in the sagittal plane. 5,9 For safe and effective TES exercise, it is necessary to minimize lumbar extensor muscle (ICL) activity to decrease the stress on the lumbar spine during exercise. Second, the synergistic activity of the erector spinae pars thoracis (ICL and LT) and lumborum (ICL) muscle is assumed to be the main mechanism of trunk extension; these muscles do not form a homogeneous muscle mass, but rather have anatomical and functional differences.…”
