The role of the facet capsular ligament in providing spinal stability.

Comput Methods Biomech Biomed Engin 2018 Oct;21(13):712-721

b Department of Rehabilitation Medicine , University of Minnesota , Minneapolis , MN , USA.

Low back pain (LBP) is the most common type of pain in America, and spinal instability is a primary cause. The facet capsular ligament (FCL) encloses the articulating joints of the spine and is of particular interest due to its high innervation - as instability ensues, high stretch values likely are a cause of this pain. Therefore, this work investigated the FCL's role in providing stability to the lumbar spine. Read More

Prevalence of back pain in a group of elite athletes exposed to repetitive overhead activity.

PLoS One 2019 24;14(1):e0210429. Epub 2019 Jan 24.

Department of Sports Medicine and Sports Nutrition, Ruhr-University Bochum, Bochum, Germany.

Background: The prevalence of back pain in athletes has been investigated in several studies, but there are still under- or uninvestigated sports discipline like sports exposed to repetitive overhead activity. Elite athletes spend much time in training and competition and, because of the nature of their disciplines, subject their bodies to a great deal of mechanical strain, which puts a high level of stress on their musculoskeletal systems. From this it is hypothesized that elite athletes who engage in repetitive overhead motions experience a higher strain on their spine and thus possibly a higher prevalence of back pain compared with an active control group.

Materials (Basel) 2019 Jan 14;12(2). Epub 2019 Jan 14.

Department of Materials Science and Engineering, Macromolecules Innovation Institute, Virginia Tech, Blacksburg, VA 24061, USA.

Disc degeneration affects 12% to 35% of a given population, based on genetics, age, gender, and other environmental factors, and usually occurs in the lumbar spine due to heavier loads and more strenuous motions. Degeneration of the extracellular matrix (ECM) within reduces mechanical integrity, shock absorption, and swelling capabilities of the intervertebral disc. When severe enough, the disc can bulge and eventually herniate, leading to pressure build up on the spinal cord. Read More

IVD progenitor cells: a new horizon for understanding disc homeostasis and repair.

Nat Rev Rheumatol 2019 Feb;15(2):102-112

Department of Orthopaedics and Traumatology, Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong SAR, China.

Intervertebral disc (IVD) degeneration is associated with low back pain. In IVDs, a high mechanical load, high osmotic pressure and hypoxic conditions create a hostile microenvironment for resident cells. How IVD homeostasis and function are maintained under stress remains to be understood; however, several research groups have reported isolating native endogenous progenitor-like or otherwise proliferative cells from the IVD.

The relationship between catastrophizing and altered pain sensitivity in patients with chronic low-back pain.

Pain 2018 Dec 7. Epub 2018 Dec 7.

Department of Anesthesiology and Pain Medicine, Brigham and Women's Hospital, Harvard Medical School, Chestnut Hill, MA, United States.

Changes in central pain processing have been shown in patients with chronic low-back pain (cLBP). We used quantitative sensory testing methods to identify differences in pain sensitization between patients with cLBP (N = 167) and healthy controls (N = 33). Results indicated that, compared with healthy pain-free controls, cLBP patients showed increased sensitivity and greater painful aftersensations for mechanical pressure and pin-prick stimuli and lower tactile spatial acuity in the 2-point discrimination task (ps < 0.

What do you expect? Catastrophizing mediates associations between expectancies and pain-facilitatory processes.

Eur J Pain 2018 Dec 3. Epub 2018 Dec 3.

Department of Anesthesiology, Brigham and Women's Hospital Pain Management Center, Harvard Medical School, Chestnut Hill, Massachusetts.

Background: Pain expectancies are associated with altered pain sensitivity in individuals with chronic pain. However, little is known about the processes by which pain expectancies impact pain processing. This study assessed the association between pain expectancies and temporal summation (TS) of pain, and examined whether pain catastrophizing mediated this association. Read More

Influence of Motion Therapy in the Prevention of Lumbar Pain Syndrome Relapse.

Med Arch 2018 Oct;72(4):267-271

University of Sarajevo, Faculty of Health Studies, Bolnička 25, Sarajevo, Bosnia and Herzegovina.

Introduction: Lumbar pain syndrome is one of the most common conditions in clinical practice, more common than 290 other pathological conditions, which affect up to 84% of adults in a certain period of their life. The origin of the lower back pain can be classified as mechanical, neuropathic and secondary due to another illness. Patient education and information, muscle strengthening exercises, maintenance of routine daily physical activity and pain therapy are the basis of acute non-specific pain syndrome therapy.

Effects of a passive exoskeleton on the mechanical loading of the low back in static holding tasks.

J Biomech 2019 Jan 26;83:97-103. Epub 2018 Nov 26.

Department of Human Movement Sciences, Faculty of Behavioural and Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam Movement Sciences, The Netherlands.

With mechanical loading as the main risk factor for LBP in mind, exoskeletons are designed to reduce the load on the back by taking over a part of the required moment. The present study assessed the effect of a passive exoskeleton on back and abdominal muscle activation, hip and lumbar flexion and on the contribution of both the human and the exoskeleton to the L5/S1 net moment, during static bending at five different hand heights. Two configurations of the exoskeleton (LOW & HIGH) differing in angle-torque characteristics were tested. Read More

Dietary advanced glycation end-product consumption leads to mechanical stiffening of murine intervertebral discs.

Dis Model Mech 2018 12 18;11(12). Epub 2018 Dec 18.

Leni & Peter W. May Department of Orthopaedics, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA

Back pain is a leading cause of disability and is strongly associated with intervertebral disc (IVD) degeneration. Reducing structural disruption and catabolism in IVD degeneration remains an important clinical challenge. Pro-oxidant and structure-modifying advanced glycation end-products (AGEs) contribute to obesity and diabetes, which are associated with increased back pain, and accumulate in tissues due to hyperglycemia or ingestion of foods processed at high heat.

Interventions for preventing intensive care unit delirium in adults.

Cochrane Database Syst Rev 2018 11 23;11:CD009783. Epub 2018 Nov 23.

The Neuroscience Centre, Rigshospitalet, University of Copenhagen, Blegdamsvej 9, Copenhagen, Denmark, 2100.

Background: Delirium is defined as a disturbance in attention, awareness and cognition with reduced ability to direct, focus, sustain and shift attention, and reduced orientation to the environment. Critically ill patients in the intensive care unit (ICU) frequently develop ICU delirium. It can profoundly affect both them and their families because it is associated with increased mortality, longer duration of mechanical ventilation, longer hospital and ICU stay and long-term cognitive impairment.

Are improvements in symptoms associated with changes in lumbopelvic posture in patients with posterior derangement using Mechanical Diagnosis and Therapy?

J Back Musculoskelet Rehabil 2018 Nov 9. Epub 2018 Nov 9.

Faculty of Health and Wellbeing, Sheffield Hallam University, Sheffield, UK.

Background: Mechanical Diagnosis and Therapy (MDT) manages low back pain (LBP) with subgroup classifications. For a subgroup of the posterior derangement syndrome, postural education limiting lumbar flexion is included. However, it is not known if habitual posture in this subgroup actually changes through MDT management because of technical difficulties in monitoring habitual lumbopelvic posture. Read More

Directional preference constructs for patients' low back pain in the absence of centralization.

J Man Manip Ther 2018 Dec 6;26(5):281-291. Epub 2018 Aug 6.

Department of Statistics, Florida State University, Tallahassee, FL, USA.

A detailed description of how Directional Preference (DP) constructs are measured could accelerate research to practice translation and improve research findings for Mechanical Diagnosis and Therapy (MDT) stakeholders. A secondary analysis of a prospective, observational cohort study was conducted to understand (1) the type and prevalence of DP constructs at first examination and (2) the relationships between DP constructs and clinical outcomes at follow-up. Data were collected and analyzed from 1485 consecutive patients who presented to outpatient, private practice clinics with primary complaints of non-specific low back pain (LBP); 400 patients met the inclusion criteria and completed first examination and follow-up data.

Image-based multi-scale mechanical analysis of strain amplification in neurons embedded in collagen gel.

Comput Methods Biomech Biomed Engin 2018 Nov 17:1-16. Epub 2018 Nov 17.

a Scientific Computational Research Center , Rensselaer Polytechnic Institute, Low Center for Industrial Innocation , Troy , NY , USA.

A general multi-scale strategy is presented for modeling the mechanical environment of a group of neurons that were embedded within a collagenous matrix. The results of the multi-scale simulation are used to estimate the local strains that arise in neurons when the extracellular matrix is deformed. The distribution of local strains was found to depend strongly on the configuration of the embedded neurons relative to the loading direction, reflecting the anisotropic mechanical behavior of the neurons.

Charcot spinal arthropathy presenting as adjacent segment disease after lumbar spinal fusion surgery in Parkinson's disease: A case report.

J Clin Neurosci 2018 Nov 13. Epub 2018 Nov 13.

Department of Orthopaedic Surgery, Faculty of Medicine, University of Tsukuba, 1-1-1 Tennodai, Tsukuba, Ibaraki 305-8575, Japan.

Charcot spinal arthropathy (CSA) is a rare spinal disorder presenting neuropathic osteoarthropathy of facet joints leading to progressive destruction. After L4-5 PLIF, a 63-year-old woman with Parkinson's disease (PD) underwent L3-4 and L5-S1 PLIF for primary adjacent segment disease caused by degenerative change, which was found as facet joint osteophytes and a vacuum disc phenomenon with endplate sclerosis. However, her postural disorder from PD deteriorated, and strong opioid analgesics were administered for severe recurring low back pain. Read More

Design and Pilot Evaluation of a Reconfigurable Spinal Exoskeleton.

Conf Proc IEEE Eng Med Biol Soc 2018 Jul;2018:1731-1734

Low back pain is a leading cause of disability, and there is a tremendous need for nonsurgical, nonpharmaceutical interventions to manage it. Versatile spinal exoskeletons have been proposed as a method of supporting or augmenting the wearer, but experimental data from human subjects are limited, and the effects of such exoskeletons remain poorly understood. We thus present a prototype of a reconfigurable spinal exoskeleton that features easily adjustable resistance and compression at multiple spinal levels, allowing us to study the effect of different exoskeleton configurations on the body.

Multiscale modelling of the human lumbar facet capsular ligament: analysing spinal motion from the joint to the neurons.

J R Soc Interface 2018 Nov 14;15(148). Epub 2018 Nov 14.

Department of Biomedical Engineering, University of Minnesota, Minneapolis, MN 55455, USA

Due to its high level of innervation, the lumbar facet capsular ligament (FCL) is suspected to play a role in low back pain (LBP). The nociceptors in the lumbar FCL may experience excessive deformation and generate pain signals. As such, understanding the mechanical behaviour of the FCL, as well as that of its underlying nerves, is critical if one hopes to understand its role in LBP. Read More
