A study examining the purported link between lower back pain (LBP) and lumbar disc degeneration (LDD) determined evidence of an association between LBP and hip or knee osteoarthritis. A review of several published observational studies was unable to establish an association between LBP and osteophytes, though a moderate association between LBP (particularly neuropathic pain) and […]
A review of published research on the implications of patient Healthcare Literacy (HL) in patients with lower back pain (LBP) found that evidence-based studies were minimal and that further research could be beneficial in determining future treatment costs and outcomes. The ability of chronic pain sufferers to access, understand, and apply health information defines HL […]
Follow-Up Study Finds Lumbar Transforaminal Epidural Steroid Injections Offer Only Temporary Pain Relief
A post-five-year physician follow-up of a predetermined study group of patients who had received lumbar transforaminal epidural steroid injections (TFESI’s) to treat acute unilateral lumbar pain from their single level herniated nucleus found that, although the procedure offered temporary relief, most patients reported needed some type of additional pain intervention (medicinal, another TFESI, or back […]
An investigation of degenerative joint disease (DJD) studied data from chimpanzees, lowland gorillas, bonobos, and human samples to ascertain the relative rate of osteoarthritis and peripheral joint osteoarthritis in each species and found that all types of apes were significantly less prone to DJD than humans. The Study Museum skeletal samples of adult chimpanzees, […]

A radiographic study of the effect of hypo- and hyper-lordosis in the lumbar spine concluded that a lordosis angle of between 65-68 degrees can be considered ‘optimal’ in the reduction of degenerative joint disease (DJD) of the lumbar spine. The results of the study should be helpful in the treatment of spinal pain and rehabilitation. […]

A study 1 on the impact of different office chair features on spinal posture while sitting found that seat pan tilt and some types of lumbar supports may offer negligible improvement in sitting postures, but overall, sitting for extended periods of time puts stress on the spine and may generate spinal injury. Perhaps something new […]

A microstructural analysis of how healthy discs respond to compression and complex loading postures—specifically those incorporating flexion and facet-constrained shear—found evidence that the required load contributing to disc failure was reduced when complex postures, rather than simple flexion, were utilized in load-bearing situations. In addition, when asymmetric postures were used during lifting, rather than simple […]

A new study 1 to determine which mechanical conditions were unsafe for the intervertebral disc (IVD) culminated with the presentation of a numerical model that can be used to predict disc failure under all loading conditions. Using a series of complex loading conditions on ovine lumbar IVD segments, researchers were able to examine the state […]

Increasing Gradients of Compressive Stress Can Lead to Annular Delamination, Collapse, and IVD Degeneration
A ISSLS Prize-winning study 1 examined how increasing gradients of compressive stress within the intervertebral disc (IVD) contributed to the progress of dis degeneration. The research findings suggest that an increased grade of disc degeneration created decreased nucleus pressure and compressive annulus stress, but anterior annular stress gradients increased by approximately 75 percent, and by […]
Kinematics Study of Lumbar Disc Herniation Impact on Activities Involving Lower Extremities, Pelvis, and Multi-segmental Spine
A study of 26 healthy and seven male patients with lower back disc herniation (LDH) investigated the kinematic effects of LDH on the multi-segmental spine, pelvis, and lower extremities during activities of daily living (ADL). The intent of the study was to help establish a clearer understanding of how LDH affects the movement of the […]
A study 1. [Beliefs in the population about cracking sounds produced during spinal manipulation] of 100 individuals indicates most spinal patients have false beliefs regarding cavitation sounds during spinal manipulation and that those incorrect beliefs can inhibit patient wellness when the patient either refuses potentially beneficial spinal manipulation or develops the nocebo effect when no […]

The spine undergoes an accordion-like cycle of compression and decompression. This variation occurs not exclusively with the sleep-wake cycle but with the gravity. Researchers have long known that the spine undergoes a diurnal variation with compression changes of water exchange in and out of the intervertebral discs. Much of the attention has been on the discs of […]
Connecting with patients is the future of healthcare. With low back pain and neck pain as the leading cause of disability and lost work days on this planet, getting to the roots of helping people with these conditions is imperative. These origins are mostly biomechanical in nature. But how a practitioner connects the curious patient […]

Lumbar disc herniation is a very common condition which often generates pain and disability. It is a physiological process that starts from the inside out as the nucleus pushes radially into the annulus fibrosus. But not all disc herniations cause pain and many of them don’t cause long term disability. The literature has been quite […]

Aging and Degenerative Disc Changes of the IVD’s Impact on Spinal Flexibility A publication reviewed several studies involving the biomechanics of the intervertebral discs (IVD) with macroscopic changes associated with degenerative disc disease with the aim of finding out how spinal flexibility was affected by dehydration, tears, fissures, osteophytes, and the inevitable collapse of the […]
