Lumbar Flexion and Kinesiophobia | Task-Specific Fear Research

Goal of the Study? This study aims to assess whether someone is generally fearful of painful movement or is it related to a specific task. It is common for those with chronic low back pain to experience an avoidance and fear of movement, likely…

Tensile forces create spinal spurs | Biomechanical Evaluation of Spondylophyte Development

Goal of the Study? Bone spurs that project off vertebral bodies (spondylophytes) are common. However, the causes of their development are somewhat curious. Are these vertebral spurs due to tensile (stretching/lengthening) forces, or are they…

Vacuum Phenomenon – What is it and can it tell us anything about the dynamics of the spine?

Goal of the Study? Intradiscal vacuum phenomenon is a commonly observed radiological finding in the spine but not much is known about its pathophysiology. A recent paper was published in The European Spine Journal[1.Advanced disc degeneration,…

More Inclusive Framework Needed in Future Study of Spinal Stability

The authors of a clinical commentary [1. Are Stability and Instability Relevant Concepts for Back Pain?] stress the necessity of a unifying framework in which to explore issues of spinal stability—one that broadens the current definition to…

Motor Control Phenotyping May Help Target Treatment for Lower Back Pain Patients

Lower back pain (LBP) patients present with a wide variety of motor control adaptations in response to, and in anticipation of pain. Though these adaptations manifest across a spectrum of functionality, studies have indicated two common phenotypes…

Study Finds Strong Correlation Between LBP, Age-related Degeneration, and Spinal Instability

A study examined the relationship between lumbar disc degeneration and instability in spinal segments of three groups of volunteers and found that factors of spinal instability were closely related to disc height and the age of the study subjects…

Disc Height Loss and Preclinical Instability

Disc height loss is the common theme in back pain. And with early disc height loss, hypermobility is related. But how are they associated to one another? Barr in 1948 (1) was the first to describe instability. His description of low back pain…
