Abstract
OBJECTIVES This study aimed at devising an objective method for quantifying pain in the low back region using pressure pain threshold (PPT) and demographic factors as predictive variables. METHODS The research was conducted in two phases. Phase I was a longitudinal exploratory study conducted on 49 men aged 18-50 years with chronic low back pain (CLBP) recruited using non-probability purposive sampling. We used Visual Analogue Scale to record pain intensity and pain affect, and Disability Rating Index to record associated disability. PPT was measured on 12 different locations on the lower back using a manual algometer. These measurements were taken from each participant in 1 to 6-follow-up visits, depending on improvement in the individual's symptoms. In phase II additional 33 subjects, both men and women with varying durations of low back pain were recruited using non-probability convenience sampling. Repeated measures ordinal regression and receiver's operating characteristic curve analyses were performed to develop predictive models using STATA V.16.0 and R V.3.5.2 software. These models were given an interface using Microsoft Excel. A p value of <0.05 was considered statistically significant. RESULTS Higher PPT scores, increased lean body mass, lean physique and a longer duration of CLBP were associated with a reduction in CLBP intensity, affect and disability. Advancing age was associated with an increase in these outcomes. Collectively, these factors were found to predict pain intensity, affect, and disability with 63%-65% diagnostic accuracy in phase I, however, this diagnostic accuracy increased to 65%-78% in phase II. CONCLUSION We developed a new outcome tool 'Pain Calculator' that can objectively measure low back pain with sufficient statistical accuracy. With further refinement, this tool in the future can be configured to measure somatic pain in different regions as well, affording clinicians and researchers much-needed objectivity while recording pain levels. TRIAL REGISTRATION NUMBER NCT04482075.

Armitage AJ, Miller JM, Sparks TH, Georgiou AE, Reid J. Efficacy of autologous mesenchymal stromal cell treatment for chronic degenerative musculoskeletal conditions in dogs: A retrospective study. Front Vet Sci 2023; 9:1014687. [PMID: 36713862 PMCID: PMC9880336 DOI: 10.3389/fvets.2022.1014687] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 12/27/2022] [Indexed: 01/15/2023] Open
Abstract
Introduction The objective of this study was to retrospectively analyze clinical data from a referral regenerative medicine practice, to investigate the efficacy of autologous mesenchymal stromal cells (MSC) in 245 dogs deemed unresponsive to conventional treatment by their referring vet. Methods Diagnostic imaging [radiology and musculoskeletal ultrasound (MSK-US)] identified musculoskeletal pathology holistically. MSCs, produced according to current guidelines, were initially administered with PRP by targeted injection to joints and/or tendons, with a second MSC monotherapy administered 12 weeks later to dogs with severe pathology and/or previous elbow arthroscopic interventions. Dogs with lumbosacral disease received epidural MSCs with additional intravenous MSCs administered to dogs with spondylosis of the cervical, thoracic and lumbar spine. All dogs received laser therapy at 10 J/cm2 at the time of treatment and for 5 sessions thereafter. Objective outcome measures (stance analysis, range of joint motion, pressure algometry) and validated subjective outcome measures (owner reported VetMetrica HRQL™ and veterinary pain and quality of life impact scores) were used to investigate short and long-term (6-104 weeks) efficacy. Outcome data were collected at predetermined time windows (0-6, 7-12, 13-18, 19-24, 25-48, 49-78, 79-104) weeks after initial treatment. Results There were statistically significant improvements in post compared with pre-treatment measures at all time windows in stance analysis, shoulder and hip range of motion, lumbosacral pressure algometry, and to 49-78 weeks in carpus and elbow range of motion. Improvements in 4 domains of quality of life as measured by VetMetricaTM were statistically significant, as were scores in vet-assessed pain and quality of life impact. In dogs receiving one initial treatment the mean time before a second treatment was required to maintain improvements in objective measures was 451 days. Diagnostic imaging confirmed the regenerative effects of MSCs in tendinopathies by demonstrating resolution of abnormal mineralization and restoration of normal fiber patterns. Discussion This represents the first study using "real-world" data to show that cell-based therapies, injected into multiple areas of musculoskeletal pathology in a targeted holistic approach, resulted in rapid and profound positive effects on the patient's pain state and quality of life which was maintained with repeat treatment for up to 2 years.

The Effects of an Acute Maximal Seated Lumbar Spine Flexion Exposure on Low Back Mechanical Pain Sensitivity. J Appl Biomech 2022; 38:12-19. [PMID: 34969008 DOI: 10.1123/jab.2021-0238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 10/01/2021] [Accepted: 10/27/2021] [Indexed: 11/18/2022]
Abstract
Viscoelastic creep generated in the lumbar spine following sustained spine flexion may affect the relationship between tissue damage and perceived pain. Two processes supporting this altered relationship include altered neural feedback and inflammatory processes. Our purpose was to determine how low back mechanical pain sensitivity changes following seated lumbar spine flexion using pressure algometry in a repeated-measures, cross-sectional laboratory design. Thirty-eight participants underwent a 10-minute sustained seated maximal flexion exposure with a 40-minute standing recovery period. Pressure algometry assessed pressure pain thresholds and the perceived intensity and unpleasantness of fixed pressures. Accelerometers measured spine flexion angles, and electromyography measured muscular activity during flexion. The flexion exposure produced 4.4° (2.7°) of creep that persisted throughout the entire recovery period. The perception of low back stimulus unpleasantness was elevated immediately following the exposure, 20 minutes before a delayed increase in lumbar erector spinae muscle activity. Women reported the fixed pressures to be more intense than men. Sustained flexion had immediate consequences to the quality of mechanical stimulus perceived but did not alter pressure pain thresholds. Neural feedback and inflammation seemed unlikely mechanisms for this given the time and direction of pain sensitivity changes, leaving a postulated cortical influence.

Pressure pain threshold map of thoracolumbar paraspinal muscles after lengthening contractions in young male asymptomatic volunteers. Sci Rep 2022; 12:15825. [PMID: 36138196 PMCID: PMC9499944 DOI: 10.1038/s41598-022-20071-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 09/08/2022] [Indexed: 11/30/2022] Open
Abstract
This study aimed to characterise topographic distribution of pressure pain thresholds (PPTs) of thoracolumbar paraspinal muscles and its change after lengthening contractions (LCs) of the back muscles. Using young male asymptomatic participants in Experiment 1, we systematically examined the distribution of PPTs bilaterally in the range of Th1–L5 at measurement points 2 and 4 cm from the midline. PPTs were found to be higher in the lumbar segments of the paraspinal muscles than in the thoracic segments, and in muscles closer to the vertebrae (2 vs. 4 cm from the midline). The PPTs did not differ between the left and right sides in each segment. In Experiment 2, LC was applied by asking a part of participants recruited in Experiment 1 to fall their trunk from a starting position (parallel to the floor) to 40° flexed position, and then made it back as quickly as possible to the starting position. This cycle was repeated until participants could not keep contractions (30 times/set, 25.4 ± 10.6 sets). PPTs of the LC group decreased prominently in the lower thoracic and lumbar segments, and the decrease was more evident 24 h after LC compared to that 48 h after. In contrast, PPTs in the control group without LC remained unchanged. These results provided broad topographic images of PPTs in the thoracolumbar paraspinal muscles of young male participants with and without LC, and the obtained PPT maps could be a useful guide for better treatment of exercise-induced myofascial pain in the lower back.

Current Concept of Quantitative Sensory Testing and Pressure Pain Threshold in Neck/Shoulder and Low Back Pain. Healthcare (Basel) 2022; 10:healthcare10081485. [PMID: 36011141 PMCID: PMC9408781 DOI: 10.3390/healthcare10081485] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 08/02/2022] [Accepted: 08/03/2022] [Indexed: 11/18/2022] Open
Abstract
In recent years, several published articles have shown that quantitative sensory testing (QST) and pressure pain threshold (PPT) are useful in the analysis of neck/shoulder and low back pain. A valid reference for normal PPT values might be helpful for the clinical diagnosis of abnormal tenderness or muscle pain. However, there have been no reliable references for PPT values of neck/shoulder and back pain because the data vary depending on the devices used, the measurement units, and the area examined. In this article, we review previously published PPT articles on neck/shoulder and low back pain, discuss the measurement properties of PPT, and summarize the current data on PPT values in patients with chronic pain and healthy volunteers. We also reveal previous issues related to PPT evaluation and discuss the future of PPT assessment for widespread use in general clinics. We outline QST and PPT measurements and what kinds of perceptions can be quantified with the PPT. Ninety-seven articles were selected in the present review, in which we focused on the normative values and abnormal values in volunteers/patients with neck/shoulder and low back pain. We conducted our search of articles using PubMed and Medline, a medical database. We used a combination of “Pressure pain threshold” and “Neck shoulder pain” or “Back pain” as search terms and searched articles from 1 January 2000 to 1 June 2022. From the data extracted, we revealed the PPT values in healthy control subjects and patients with neck/shoulder and low back pain. This database could serve as a benchmark for future research with pressure algometers for the wide use of PPT assessment in clinics.

Serum apolipoprotein B/apolipoprotein A1 ratio in relation to intervertebral disk herniation: a cross-sectional frequency-matched case-control study. Lipids Health Dis 2021; 20:79. [PMID: 34325707 PMCID: PMC8320064 DOI: 10.1186/s12944-021-01502-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 07/12/2021] [Indexed: 12/04/2022] Open
Abstract
Study design This was a cross-sectional frequency-matched case–control study. Background and aim The serum lipid profile of lipoprotein(a) [Lp(a)] level and apolipoprotein B/apolipoprotein A1 ratio (Apo B/Apo A1) ratio were found to be more representative for serum lipid level and were recognized as the independent risk factors for various diseases. Although the blood levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were found to be associated with symptomatic intervertebral disk herniation (IDH), no studies to date have evaluated the association of Apo AI, Apo B, Lp(a), and Apo B/Apo AI levels with symptomatic IDH. This study aimed to assess the link between blood lipid levels and symptomatic IDH. Method The study included 1839 Chinese patients. Of these, 918 patients were diagnosed with IDH and enrolled in the experimental group. A control group of 921 patients underwent a physical examination during the same period. The serum lipid levels of TC, TG, LDL-C, HDL-C, Lp(a), Apo B, and Apo B/Apo AI were examined and analyzed. The control group comprised randomly selected patients who met the baseline levels of the aforementioned lipid molecules. Results Patients with IDH exhibited significantly higher TC, TG, LDL, Apo B, and Lp(a) levels than controls. The percentage of high TC, high TG, high LDL, high Apo B, and high Lp(a) were obviously higher in the IDH group than in the control group. However, hyperlipidemia had no relationship with the degenerated segment of the IDH (P = 0.201). The odds ratio (OR) for the incidence of IDH with elevated levels of LDL-C, TC, TG, Lp(a), Apo B, and Apo B/Apo AI was 1.583, 1.74, 1.62, 1.58, 1.49, and 1.39, respectively. The correlation analysis revealed the correlation between elevated LDL-C, TC, TG, Apo B, Lp(a), and incidence of IDH was significant (R2LDL = 0.017; R2TC = 0.004; R2TG = 0.015; R2Apo B = 0.004; R2Lp(a) = 0.021) (P < 0.05). Conclusion This study suggested that elevated levels of serum TC, TG, LDL, Apo B, Lp(a), and Apo B/Apo AI were associated with a higher risk of IDH. This study provided useful information to identify a population that might be at risk of developing IDH based on elevated lipid levels.

Curve Characteristics and Response of Sciatic and Olisthesis Scoliosis Following L5/S1 Transforaminal Lumbar Interbody Fusion in Adolescent Lumbar Spondylolisthesis. Neurosurgery 2021; 88:322-331. [PMID: 33017018 DOI: 10.1093/neuros/nyaa429] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Accepted: 07/02/2020] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Lumbosacral spondylolisthesis-induced scoliosis is a rare clinical entity. Sagittal reconstruction and the coronal curve evolution after surgery for spondylolisthesis have not been investigated in depth. OBJECTIVE To compare the curve characteristics between sciatic scoliosis and olisthetic scoliosis and to further investigate the effects of lumbosacral transforaminal lumbar interbody fusion (TLIF) on scoliosis evolution. METHODS Adolescents with sciatic scoliosis group (SS group) or olisthetic scoliosis group (OS group) who underwent L5/S1 TLIF from 2010 to 2017 and were followed up for at least 2 yr were retrospectively reviewed. Radiographic parameters and patient-reported outcomes were evaluated. RESULTS There were 20 patients in the SS group (M/F: 8/12; age: 15.6 ± 2.2 yr) and 16 in the OS group (M/F: 6/10; age: 16.8 ± 2.5 yr). Both groups had similar preoperative Cobb angles, but more patients with coronal imbalance were observed in the SS group. Moreover, the OS group showed significantly larger L5 tilt and rotation. After surgery, the slip reduction rate of the SS group and OS group were 76.1% ± 12.4% and 79.4% ± 9.6%, respectively. Scoliosis resolution was observed in all patients in the SS group but only in 9 patients (56.2%) in the OS group. Patients with failed scoliosis resolution in the OS group were older and had a larger Cobb angle and L5 rotation compared with those with successful scoliosis resolution. CONCLUSION Lumbosacral TLIF can achieve satisfactory slip reduction and scoliosis resolution. Sciatic scoliosis often presents with coronal imbalance but also a preferable curve prognosis. A large Cobb angle and L5 rotation may hinder the resolution of olisthetic scoliosis.

Abstract
BACKGROUND Changes in trunk and hip muscles are believed to be important in subjects with nonspecific chronic low back pain (NSCLBP), but little is known about specific changes, or how they might be affected by core stabilization exercises. The aim of this study was to compare six key muscles before and after these exercises. METHODS Thirty two NSCLBP patients were assigned randomly into two groups: exercise (n = 17) and control (n = 15). On 5 days per week for 4 weeks, the Exercise group performed 16 core stabilization exercises and the Control group received transcutaneous electrical nerve stimulation and a 'hot-pack'. Surface electromyography (EMG) was used to assess maximum bilateral activity of transversus abdominis (TrA), multifidus (MF) and gluteus maximus (Gmax) muscles. Ultrasound imaging was used to measure the rest and contracted thickness of these muscles. Pain and disability were assessed using a visual analogue scale (VAS) and the Oswestry Disability Index. RESULTS When left and right-side muscle data were combined, two-way ANOVAs showed a nonsignificant interaction effect for all dependent variables (P > 0.05), significant time effects on resting muscle thickness for TrA (P = 0.01), MF (P = 0.041) and Gmax (P = 0.003), EMG signals of TrA (P = 0.038), pain and disability (P = 0.000). There were a significant group effect on contracted thickness for TrA (P = 0.032) and Gmax (P = 0.026) and disability (P = 0.017). CONCLUSIONS Core stabilization exercises increased contracted thickness of TrA and Gmax muscles and decreased disability in subjects with NSCLBP.

Abstract
Background Low back pain (LBP) is common in the elderly and an appropriate intervention for LBP management should be investigated. The aim of this study is to investigate the potential of mud-heat intervention combined with core exercise as an alternative intervention for relieving pain and improving motor function in individuals with nonspecific chronic LBP. Methods Thirty-one individuals with chronic nonspecific LBP were randomly allocated to either the intervention group (n = 16) or the control group (n = 15). The intervention group used a mud pack for 30 min and performed a core-exercise program for 50 min twice a day for 4 days (8 sessions). The control group performed the core-exercise program only, at the same time point as the intervention group. Pain intensity was assessed using a 100 mm visual analog scale and a pain pressure threshold (PPT) as the primary outcomes. The secondary outcome measures included functional disability by LBP (Oswestry Disability Index), muscle properties, and static/dynamic balance. Results There was a significant group difference in pain intensity at rest (p=0.048) and in the PPT at the two sites assessed (2 cm lateral to L3 spinous process, p=0.045; 2 cm lateral to L5 spinous process, p=0.015). No group differences were found in terms of muscle properties. Compared to core exercise only, moor-heat therapy and core exercise showed a significant improvement in static balance (p=0.026) and dynamic balance (p=0.019). Conclusion Mud therapy combined with core exercise is effective in relieving pain and improving motor function in patients with chronic nonspecific LBP. Further research is needed to underpin these preliminary results.

Abstract
Context: Kinesio taping® (KT) is a therapeutic modality frequently used in the clinical practice for the treatment of various musculoskeletal disorders. It is often applied in patients with chronic low back pain to decrease pain and improve functional capacity. However, it is not known, whether thoracolumbar fascia KT technique can decrease back pain, restore normal activity of paraspinal muscles, and improve functional capacity in patients with lumbar disk herniation (LDH). Objective: To evaluate the impact of 7-day new KT stabilizing application on lumbar paraspinal muscles function, pain perception, and disability in patients with LDH. Design: A randomized controlled trial. Setting: Human Performance Laboratory. Patients: A number of 38 patients with LDH were randomized into KT (n = 19) and placebo taping (n = 19) groups. Interventions: Both groups received the same "x" type application running over the back along fibers of superficial lamina of the posterior layer of thoracolumbar fascia. Main Outcome Measures: The primary outcome measures were flexion-relaxation and extension-relaxation ratios calculated from electromyographic activity of lumbar multifidus and longissimus thoracic muscles. Pain intensity rating (Quadruple Visual Analogue Scale), pressure pain thresholds of the lower back, Roland-Morris Disability Questionnaire score, back extension force, and flexion range of motion (ROM) were among secondary outcomes. Results: KT application did not affect the lumbar multifidus and longissimus thoracic muscles flexion-relaxation and extension-relaxation ratios, lower back pressure pain thresholds, back flexion ROM, and back extension force (no group × time interaction [GTI]). KT and placebo taping comparably decreased disability level (time effect: F1,36 = 22.817, P < .001; GTI: F1,36 = 0.189, P = .67), average pain (time effect: F1,36 =39.648, P < .001; GTI: F1,36 = 2.553, P = .12), and the worst pain (time effect: F1,36 = 36.039, P < .001; GTI: F1,36 = 0.003, P = .96) intensity. Conclusion: Seven-day KT does not normalize lumbar paraspinal muscle function and is not superior to placebo in reducing disability and pain intensity in patients with LDH.

Abstract
This study aimed to explore whether the genetic variant of COL11A1 is functionally associated with the development of lumbar disc herniation (LDH) in Chinese population. SNP rs1676486 of COL11A1 was genotyped in 647 patients and 532 healthy controls. The differences of genotype and allele distributions between LDH patients and healthy controls were evaluated using the χ² test. One-way ANOVA test was used to compare the relationship between genotypes and clinical features including tissue expression of COL11A1 and the degree of disc degeneration. Patients were found to have a significantly higher frequency of TT than the controls (10.2% versus 7.3%, P = 0.004). Besides, the frequency of allele T was found to be remarkably higher in the patients than the controls (34.8% versus 28.1%, P < 0.001) with an odds ratio of 1.36 (95% confidential interval=1.14-1.63). Patients with genotype TT were found to have remarkably more severe disc degeneration (P = 0.02). Besides, the expression of COL11A1 in the lumbar disc was significantly lower in the patients with genotype TT than in those with genotype CT or CC (P < 0.001). Moreover, the expression level was inversely correlated with the severity of disc degeneration (P < 0.001). We confirmed that the rs1676486 of COL11A may be functionally associated with LDH in the Chinese population. Extracellular matrix related proteins may play an important role in the pathogenesis of LDH. Our findings shed light on a better understanding of the pathogenesis of LDH, which could be a promising target for a novel treatment modality of LDH.

Abstract
Blebbistatin is a widely used inhibitor of myosin 2 that enables the study of a broad range of cytoskeleton-related processes. However, blebbistatin has several limitations hindering its applicability: it is fluorescent, poorly water soluble, cytotoxic, and prone to (photo)degradation. Despite these adverse effects, being the only available myosin 2-specific inhibitor, blebbistatin is rather a choice of necessity. Blebbistatin has been modified to improve its properties and some of the new compounds have proven to be useful replacements of the original molecule. This review summarizes recent results on blebbistatin development. We also discuss the pharmacological perspectives of these efforts, as myosins are becoming promising drug target candidates for a variety of conditions ranging from neurodegeneration to muscle disease, wound healing, and cancer metastasis.

Abstract
BACKGROUND Lumbar intervertebral disc herniation affects a large number of patients annually and are the most common cause of sciatica. OBJECTIVES This study was aimed at measuring the spino-pelvic alignment and its relation to the functional limitations in subjects with acutely herniated lumbar disc. METHODS Sixteen patients with acute Lumbar Disc Herniation (LDH group) and 16 healthy matched volunteers (healthy group) represented the sample of the study. The patients were recently diagnosed as lumbar disc herniation (L4-5 or L5-S1) with acute sciatica and antalgic posture using magnetic resonance imaging. Spino-pelvic alignment was measured via Rasterstereography. Functional disability among patients was assessed using Oswestry Disability Index Arabic version. RESULTS Trunk inclination, trunk imbalance, pelvic obliquity, pelvic torsion, lordotic and scoliotic angles were significantly different between groups (P ≤ 0.05). A non-significant difference in kyphotic angle was found between the patients and healthy controls. There was no association between the measured postural changes and functional disabilities in patients with lumbar disc herniation (P ≤ 0.05). CONCLUSION There are significant postural changes in patients with acutely herniated lumbar disc which has no relation to functional disability. These results support the concept of staying active during acute stage.

Abstract
[Purpose] The objective of this study was to investigate the effects of spinal support device (SSD) on pain and hamstring extensibility in patients with non-specific low back pain (NSLBP). [Subjects and Methods] 20 patients with NSLBP were recruited and randomly assigned to either the SSD group or the control group. In the SSD group, SSD was applied; in the control group, bed rest in supine position was performed. Both groups underwent treatment 20 min/day, 3 times a week, for a duration of 4 weeks. To assess the hamstring extensibility, sit and reach test (SRT) was performed. To assess pain pressure threshold (PPT) of the sacroiliac joint, a pressure algometer was used. Visual analog scale (VAS) was used to quantify pain. [Results] The SSD group showed a significant improvement in sacroiliac joint pain with increased VAS, and the control group showed a significantly increased VAS after intervention. In the SSD group, VAS was significantly increased, but SRT was not changed compared with the control group. [Conclusion] These results demonstrated that an application of SSD effectively attenuates low back pain. Therefore, SSD may be a suitable intervention for pain control in patients with NSLBP.

Possible involvement of the oxLDL/LOX-1 system in the pathogenesis and progression of human intervertebral disc degeneration or herniation. Sci Rep 2017; 7:7403.

Abstract
Epidemiological studies have concluded that hyperlipidemia and atherosclerosis were related to intervertebral disc degeneration (IVDD). The presence of oxidized low density lipoprotein (ox-LDL) and the expression of lectin-like oxidized low density lipoprotein receptor 1 (LOX-1) have not been explored in this tissue. In this study, we investigated the presence of ox-LDL and the expression of its receptor LOX-1 in non-degenerated, degenerated or herniated human intervertebral discs (IVDs). The expression of LOX-1 and matrix metalloproteinase 3 (MMP3) were studied after incubating nucleus pulposus cells (NPCs) with ox-LDL. The presence of ox-LDL and LOX-1 was positively related with the extent of IVDD in nucleus pulposus (NP), end-plate cartilage and outer annulus fibrous, but not with the extent of degeneration of inter annulus fibrous. Ox-LDL significantly reduced the viability of human NPCs in a dose and time-dependent manner, and increased the expression of MMP3 induced by LOX-1. Pretreatment with anti-human LOX-1 monoclonal antibody reversed these effects. Ox-LDL, principally mediated by LOX-1, enhanced MMP3 production in NPCs through the NF-κB signaling pathway. In conclusion, increased accumulation of ox-LDL and LOX-1 in IVDs indicates a specific role of the receptor-ligand interaction in degeneration or herniation of IVDs.

Abstract
Background Abnormal serum lipid levels have been shown to be associated with the occurrence of atherosclerosis, but little is known about the relationships of them with the risk of developing intervertebral disc degeneration (IVDD) in Chinese population. Methods We performed a case–control study to assess the relationship between serum lipid levels and lumbar disc degeneration. A total of 790 Chinese patients were recruited for this study at the time of hospitalization. We examined fasting serum lipid levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). 396 patients (235 men and 161 women; mean age: 41.07 years) underwent surgery for single-level lumbar disc herniation. A control group of 394 patients (225 men and 169 women; mean age: 42.1 years) underwent surgery for wounded lower limbs during the same period. Patients in the control group were collected randomly from among patients who were age- and sex-matched patients with the case group. Results Patients with lumbar disc herniation had significantly higher TC and LDL-C serum concentrations (P < 0.001 for both) than controls. Percentage of High-TC, High-TG, High-LDL-C, borderline High-TC and borderline High-LDL-C were significantly higher in the disc herniation group (P = 0.017, P = 0.002, P = 0.039, P =0.002 and P < 0.001, respectively). Ratios of TC/HDL-C and LDL-C/HDL-C were significantly associated with disc herniation (P < 0.001 for both). Logistic regression revealed that patients with higher serum LDL-C levels had a higher risk of disc herniation, in which odds ratio (OR) was 1.462 and confidence interval (CI) was 1.179 ~ 1.813. Moreover, patients with High-TG and borderline High-LDL-C had a higher probability of disc herniation (OR: 2.974, CI: 1.488 ~ 5.945, statistical power: 100 %; OR: 1.626, CI: 1.012 ~ 2.612, statistical power: 61.4 %, respectively). However, hyperlipidaemia did not seem to be associated with the herniated segment of the lumbar intervertebral disc (p = 0.374). Conclusions The present study suggests that dyslipidaemia may be associated with a higher risk of developing lumbar disc herniation. Serum lipid levels could be a useful predictor for intervertebral disc degeneration in Chinese population.

Abstract
Introduction Pregnancy is characterized by several changes in her body. These changes contribute to the emergence of low back pain, which may influence the quality of sleep during pregnancy. Objective To compare the quality of sleep among pregnant women with and without low back pain during pregnancy, examining the relationship between two variables. Materials methods Thirty volunteers aged between 19 and 36 years, divided into control group (CG – n = 16) and Study Group (SG – n = 14), residents in the cities of Natal, were evaluated in the second trimester of pregnancy. To sleep evaluation were used to index the Pittsburgh Sleep Quality and the Epworth Sleepiness Scale. Low back pain was evaluated using the pressure algometer, Visual Analogue Scale (VAS) and Oswestry Disability Index. Statistical analysis used the Shapiro Wilk test, Student’s T test for independent samples and Pearson correlation test. Results The mean gestational and chronological ages were 28.2 ± 3.4 years and 19.9 ± 3.7 weeks, respectively. Sleep quality was lower in SG (8.21 ± 4.8) when compared to CG (5.94 ± 1.7) and was statistically significant (P = 0.021). Analyzing the relationship between sleep quality and pain intensity, it was observed that the variables have a positive correlation between them (r = 0.372, P = 0.043). Conclusion Our findings indicate that sleep quality is decreased in women with low back pain compared to those without pain.

Abstract
ABSTRACT
Objective:
We compared pain severity and time to resumption of activities in patients with cervical strains treated with a nonsteroidal anti-inflammatory drug (NSAID), a centrally acting muscle relaxant or both.
Methods:
We performed a double-blinded, randomized controlled trial of adults with cervical strains from motor vehicle collisions or from falls who presented to a suburban academic emergency department (ED). Patients were randomly assigned to receive ibuprofen 800 mg, cyclobenzaprine 5 mg or both, 3 times daily as needed for up to 7 days. Outcome measures included a pain score on a 100-mm visual analog scale, pain relief scores, the time to resumption of normal activities, the use of rescue medications, and adverse outcomes. We used repeated-measures analysis of variance to compare pain relief over time. Our sample size of 20 patients in each group had a power of 80% to detect a difference of 15 mm in pain relief scores between the highest and lowest groups.
Results:
We randomly assigned 61 patients to receive ibuprofen (n = 20), cyclobenzaprine (n = 21) or both (n = 20). Mean (standard deviation) age was 34 (11) years; 58% were women and 72% were white. Although pain scores improved over time in all groups, there were no significant differences between the groups in any of the outcome measures. The rate of adverse events was also similar between groups.
Conclusion:
Our study suggests that there is little benefit to routinely using or adding cyclobenzaprine to NSAIDs for ED patients with acute cervical strain.

Abstract
BACKGROUND Fibromyalgia is a common chronic pain condition that has a significant impact on quality of life and often leads to disability. To date, there have been few well-controlled trials assessing the utility of nonpharmacological treatment modalities such as transcutaneous electrical nerve stimulation (TENS) in the management of pain and improvement in function in individuals with fibromyalgia. OBJECTIVES The purpose of this study will be to complete a long-term, multicenter study to assess the effects of TENS in women with fibromyalgia. DESIGN This will be a phase II randomized, double-blind, placebo-controlled, multicenter clinical trial. PARTICIPANTS Three hundred forty-three participants with fibromyalgia will be recruited for this study. INTERVENTION Participants will be randomly assigned to 1 of 3 groups: the intervention (TENS), placebo, or no treatment. After completing the randomized period, all participants will receive the intervention for 1 month. The participants will be asked to use TENS at the highest tolerable level for at least 2 hours daily during physical activity. MEASUREMENTS The primary outcome will be pain with movement, with secondary outcomes assessing functional abilities, patient-reported outcomes, and quantitative sensory testing. LIMITATIONS Because having participants refrain from their typical medications is not practical, their usage and any change in medication use will be recorded. CONCLUSIONS The results of this study will provide some of the first evidence from a large-scale, double-blind, placebo-controlled trial on the effectiveness of TENS on pain control and quality-of-life changes in patients with fibromyalgia.

Abstract
OBJECTIVE To investigate the effects of the CORE programme on pain at rest, movement-induced pain, secondary pain, active range of motion, and proprioception deficits in female office workers with chronic low back pain. DESIGN Randomized controlled trial. SETTING Rehabilitation clinics. SUBJECTS A total of 53 participants with chronic low back pain were randomized into the CORE group and the control group. INTERVENTION CORE group participants underwent the 30-minute CORE programme, five times per week, for eight weeks, with additional use of hot-packs and transcutaneous electrical nerve stimulation, while the control group used only hot-packs and transcutaneous electrical nerve stimulation. MAIN MEASURES Participants were evaluated pretest, posttest, and two months after the intervention period to measure resting and movement-induced pain, pressure pain as secondary pain, active range of pain-free motion, and trunk proprioception. RESULTS Pain intensity at rest (35.6 ±5.9 mm) and during movement (39.4 ±9.1 mm) was significantly decreased in the CORE group following intervention compared with the control group. There were significant improvements in pressure pain thresholds (quadratus lumborum: 2.2 ±0.7 kg/cm(2); sacroiliac joint: 2.0 ±0.7 kg/cm(2)), active range of motion (flexion: 30.8 ±14.3°; extension: 6.6 ±2.5°), and proprioception (20° flexion: 4.3 ±2.4°; 10° extension: 3.1 ±2.0°) in the CORE group following intervention (all p < 0.05). These improvements were maintained at the two-month follow-up. The control group did not show significant improvements in any measured parameter. CONCLUSION The CORE programme is an effective intervention for reducing pain at rest and movement-induced pain, and for improving the active range of motion and trunk proprioception in female office workers with chronic low back pain.

Abstract
[Purpose] This study aimed to identify the effects of the CORE exercise program on pain
and active range of motion (AROM) in patients with chronic low back pain. [Subjects and
Methods] Thirty subjects with chronic low back pain were randomly allocated to two groups:
the CORE group (n = 15) and the control group (n = 15). The CORE group performed the CORE
exercise program for 30 minutes a day, 3 times a week, for 4 weeks, while the control
group did not perform any exercise. The visual analog scale (VAS) and an algometer were
used to measure pain, and pain-free AROM in the trunk was measured before and after the
intervention. [Results] The CORE group showed significantly decreased VAS scores at rest
and during movement and had a significantly increased pressure pain threshold in the
quadratus lumborum and AROM in the trunk compared with those in the control group.
[Conclusion] This study demonstrated that the CORE exercise program is effective in
decreasing pain and increasing AROM in patients with chronic low back pain. Thus, the CORE
exercise program can be used to manage pain and AROM in patients with chronic low back
pain.

Abstract
OBJECTIVE The purpose of this study was to construct a computerized deformation-controlled indentation system and compare its test-retest reliability, repeatability, and sensitivity with a manual algometer for pressure pain threshold (PPT) measurements. METHODS Pressure pain threshold measurements were made on 16 healthy subjects for 2 sessions on bilateral erector spinae muscles at L1, L3, and L5 spinal levels, consisting of 5 repeated trials each using computerized algometry on one side and manual algometry on the other side. Mean, SD, coefficient of variation, standard error of measurement, minimal detectable change, and intraclass correlation coefficient were calculated for both manual and computerized PPT measurements. Effects of session, level, method, and side on PPT measurements were evaluated using analysis of variance. RESULTS Manual PPT measurements were significantly larger than computerized PPT measurements (P = .017), and session 2 was significantly larger than session 1 (P = .021). Coefficient of variation, intraclass correlation coefficient, standard error of measurement, and minimal detectable change of the manual and computerized PPT measurements were 10.3%, 0.91, 0.19 kg/cm(2), and 0.54 kg/cm(2) and 15.6%, 0.87, 0.26 kg/cm(2), and 0.73 kg/cm(2), respectively. CONCLUSIONS Although computerized algometry offers the benefits of eliminating the effects of operator reaction time, operator anticipation, alignment error, and variation in indentation rate on PPT measurements, these results indicate that manual algometry using load-controlled strategy may be better than computerized deformation-controlled algometry in terms of test-retest reliability, repeatability, and sensitivity. Constant load-controlled indentation protocol may be more favorable for PPT measurements. Future computerized instrumentation for PPT measurements should adopt a load-controlled mechanism.

Abstract
OBJECTIVE To determine the correlation between the degree of radiculalgia and counts of T lymphocyte subsets in the peripheral blood of patients with lumbar disc herniation. METHODS Forty-nine patients with lumbar disc herniation (group A) were divided into three subgroups according to Visual Analogue Scale (VAS) pain scores (group A(1): n= 12, VAS 0-4.0; A(2): n= 24, VAS 4.1-7.0; A(3): n= 13, VAS 7.1-10.0. Twenty health blood donors who volunteered to be involved in the study comprised the control group (group B). Peripheral blood counts of various T lymphocyte subsets were measured in each group. RESULTS (i) The counts of CD4+ T and CD4+/CD8+ lymphocytes were higher in group A than in group B, and the difference between the two groups was statistically significant (P < 0.05). There were also statistically significant differences between group A and group B in the counts of CD3+ and CD8+ T lymphocytes (P < 0.05); (ii) There was no correlation between the VAS scores and the counts of CD3+ T lymphocytes (r= 0.194, P > 0.05). A strong significant correlation was observed between the VAS scores and counts of CD4+ T lymphocytes (r= 0.542, P < 0.05), CD4+/CD8+ (r= 0.468, P < 0.05), which increased with increasing VAS scores in the three subgroups of group A (P < 0.05). However there was a significant negative linear correlation between CD8+ T lymphocyte counts and pain scores (r=-0.462, P < 0.05). CONCLUSION Our results suggest that changes in T lymphocyte subsets in peripheral blood take place after prolapse of lumbar intervertebral discs. The current results may provide support for involvement of immunologic mechanisms in low back pain secondary to herniation of the lumbar disc. T lymphocytes may play an important role in the development of symptoms in patients with lumbar intervertebral disc herniation.

Abstract
Pain is a common complaint among clients seeking physical therapy services, yet interpretation of associated sensory changes can be difficult for the clinician. Musculoskeletal injury typically results in nociceptive pain due to noxious stimuli of the damaged muscle or joint tissues. However, with progression from acute to chronic stages, altered nociceptive processing can give rise to an array of sensory findings. Specifically, patients with chronic joint injury may present with signs and symptoms typically associated with neuropathic injury, due to changes in nociceptive processing. Clinical presentation may include expansion of hyperalgesia into adjacent and remote areas, allodynia, dysesthesias, and perceptual deficits. Quantitative sensory testing (QST) may provide an objective method of examining sensation and, thereby, of recognizing potential changes in the nociceptive pathways. The purpose of this paper is to provide an overview of altered nociceptive processing and somatosensory changes that may occur following a musculoskeletal injury without associated neural injury. Recommendations are made on clinical uses of quantitative sensory testing in orthopaedic physical therapy practice, and supporting clinical and laboratory evidence are presented. Examples related to joint injury are discussed, specifically, osteoarthritis of the knee and low back pain. Quantitative sensory testing may be a useful clinical tool to aid clinical decision making and for determination of prognosis.

Abstract
Background Musculoskeletal pain in the low back and neck-shoulder regions is a major problem among the working population all over the world. The prevalence of musculoskeletal pain is found to be higher among women. Women also have lower pressure pain thresholds (PPTs) than men. Pressure pain topography aims at mapping the spatial distribution of PPT within a muscle in an attempt to track changes in mechanical sensitivity. In order to assess gender differences in the pain topography, it is necessary to map the distribution in both healthy men and women. The aim of this study was to assess PPT maps from the cervico-thoracic and lumbar regions in men and women. Methods Eleven men and eleven women without any known musculoskeletal disorders participated in the study. PPT was measured twice at 36 points over the trapezius muscle of the dominant arm, at 36 points over the trapezius muscle on the contralateral side and at 12 points over the spine between the left and right trapezius. Further, 11 points were measured over the erector spinae muscle on the left side of the spine between the first and the fifth lumbar vertebrae, 11 on the right side and 5 points on the spine itself. The measurements on each trapezius muscle were divided according to anatomical subdivisions. Three-way and two-way ANOVAs were used to analyse the differences in PPTs with the following factors: gender, locations and sub-divisions (only for cervico-thoracic region). Results There were no differences between left and right side in neither the cervico-thoracic nor the lumbar region, but there were (large effect) differences between the subdivisions in the trapezius with the lowest values in the upper part (P < 0.001; partial η2 = 0.19). Women had (small effect) lower PPT in both cervico-thoracic and lumbar regions (P ≤ 0.001; partial η2 = 0.02 for both regions), but gender had no effect on neither location nor subdivisions. Conclusions The pain topography was not found to be different between genders in the cervico-thoracic and lumbar regions. This study can be used as basis for further clinical studies on musculoskeletal disorders.

Abstract
BACKGROUND AND PURPOSE The lumbar zygapophyseal joints (LZJs) are thought to be a source of low back pain (LBP); however, no valid or reliable indicators exist. The purpose of this study was to obtain a consensus from an expert panel on the indicators of LZJ pain. SUBJECTS A multidisciplinary panel of 20 experts in the field of LBP participated in this study. METHODS A 3-round Delphi survey designed to obtain a consensus on the indicators of LZJ pain was completed by use of accepted protocols. Subjects also were asked to justify their selection of each indicator. RESULTS Following the 3 rounds, consensus was achieved, and 12 indicators were identified. Those that reached the highest levels of consensus were a positive response to facet joint injection, localized unilateral LBP, positive medial branch block, pain upon unilateral palpation of the LZJ or transverse process, lack of radicular features, pain eased by flexion, and pain, if referred, located above the knee. Justifications for the experts' selection of the indicators, predominantly based on pathoanatomical mechanisms, also were described. DISCUSSION AND CONCLUSION This Delphi survey identified 12 indicators of LZJ pain, each with an associated pathoanatomical mechanism justifying selection. This survey provides preliminary validation for these indicators, which will be of value in further research into the classification and treatment of LZJ pain.

Abstract
Recurrent disc herniation is frequently observed due to leakage of nucleus pulposus through injured anulus fibrosus. There is no effective treatment to prevent recurrent disc herniation yet. In this study, we proposed to implant non-cell-based materials into the porcine disc to stimulate the growth of fibrous tissue and thereby increase the disc functional integrity. The disc herniation was simulated by anular punctures using the spinal needles. Four clinically used implantation materials, i.e., gelfoam, platinum coil, bone cement and tissue glue, were delivered into the discs via percutaneous spinal needles. Two months after the surgery, the swine were killed. The degree of disc integrity of intact, naturally healed and implanted discs, was examined by quantitative discomanometry apparatus. We found the disc injury could not recover after 2 months of healing, and the disc implantation affected the degree of disc integrity. The disc integrity of gelfoam-implanted discs was better than that of coil-, bone cement-, and glue-implanted discs. The implantation of non-cell-based material was proved to be a potentially clinically applicable method to recover the integrity of injured discs and to prevent recurrent disc herniation.
