Biosynthesis of Human Inner Annulus Fibrosus and Nucleus Pulposus Cells May Be Related to Compressive Stress, Study Finds

Researchers observed how different magnitudes of compressive stress affected human intervertebral disc cell biosynthesis. The findings of this study [1. An in vitro study of dynamic cyclic compressive stress on human inner annulus fibrosus and nucleus pulposus cells] indicate that biosynthetic characteristics of human inner annulus fibrosus and nucleus pulposus cells may depend on the [...]

Hypermobility and Back Pain – Stability Exercises to Wind Down Pain

Hypermobility is common in the generation of back pain. Research has been revealing this for many years and recently I developed a model to help the patient see what it means to have excessive motion within the spine. Stuart McGill endorses the models I craft because it brings the research to the patients. It helps [...]

Forward Bending is the Biggest Culprit in Disc Damage

Though people usually blame lower back pain and disc damage on heavy lifting, a new study [1. Numerical Prediction of the Mechanical Failure of the Intervertebral Disc under Complex Loading Conditions]  determined that the true cause of damage is bending—specifically, in a forward direction.   While studying the effects of complex loading conditions on sheep [...]

Professor Stuart McGill uses ddd model to get his point across

Stuart McGill is a Professor of biomechanics. He has written several texbooks over his career with his latest Back Mechanic which is focused on the individual with back pain. Compared to previous books, this text is written more to the lay person while previous texts have been more to the academic audiences. As many of you know, [...]

Vibration and Back Pain – New Research Showing Damage to Discs

Vibration Research It is common to find people with back pain when exposed to vibration, especially when the spine is flexed forward in combination. In a recent prize winning vibration research paper titled: "Vibration Really Does Disrupt the Disc" [1. Kelly R. Wade, PhD, Meredith L. Schollum, PhD, Peter A. Robertson, MD, Ashvin Thambyah, PhD,and Neil [...]
