RESUMEN
BACKGROUND: Lumbar herniated nucleus pulposus (L-HNP) is a condition in which fibroblasts escape due to degenerative changes or external forces in the intervertebral disc, causing neurological symptoms by compressing the dura mater or nerve root. OBJECTIVES: The purpose of this study is to analyze and compare the effectiveness, economic feasibility, and safety of using an integrated medical service critical pathway (CP) in L-HNP patients. METHODS: This single-center prospective observational study will be performed at Kyung Hee University Medicine Hospital and Kyung Hee University Korean Medicine Hospital. The inclusion criteria are a diagnosis of L-HNP on magnetic resonance imaging or computed tomography scans, age under 80 years, a visual analog scale score of 7 or higher for either lower back pain or lower extremity pain. The included 102 participants will be classified into 6 groups (nâ =â 17 in each group): CP application with conservative treatment; CP application with open discectomy; CP application with intrabody fusion; conservative treatment without CP application; open discectomy without CP application; and interbody fusion without CP application. We will collect data on the visual analog scale, ODI, SF-36, and EQ-5D-3L scores; number of admission days; medical staff satisfaction; patients health service satisfaction; waiting time for consultations; use of pain relievers; and CP application and completion rates. CONCLUSION: In future, this study is expected to serve as a basis for follow-up studies on the development and application of CPs in integrated medical services for various diseases, including lumbar herniated nucleus pulposus.

BACKGROUND Intervertebral disc (IVD) degeneration is a common cause of lower back pain, which carries substantial morbidity and economic cost. Omega-3 fatty acids (n-3 FA) are known to reduce inflammatory processes with a relatively benign side effect profile. This study aimed to investigate the effect of n-3 FA supplementation on IVD degeneration. MATERIAL AND METHODS Two non-contiguous lumbar discs of 12 Sprague Dawley rats were needle-punctured to induce disc degeneration. Post-surgery, rats were randomly assigned to either a daily n-3 FA diet (530 mg/kg/day of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in a 2: 1 ratio, administered in sucrose solution) or control diet (sucrose solution only), which was given for the duration of the study. After 1 month, blood serum arachidonic acid/eicosapentaenoic acid (AA/EPA) ratios were analyzed. After 2 months, micro-MRI (magnetic resonance imaging) analysis and histological staining of disc explants were performed to analyze the IVD. RESULTS A reduction of blood AA/EPA ratios from 40 to 20 was demonstrated after 1 month of daily supplementation with n-3 FA. Micro-MRI analysis showed an injury-induced reduction of IVD hydration, which was attenuated in rats receiving n-3 FA. Histological evaluation demonstrated the destruction of nucleus pulposus tissue in response to needle puncture injury, which was less severe in the n-3 FA diet group. CONCLUSIONS The results of this study suggest that n-3 FA dietary supplementation reduces systemic inflammation by lowering AA/EPA ratios in blood serum and has potential protective effects on the progression of spinal disc degeneration, as demonstrated by reduced needle injury-induced dehydration of intervertebral discs and reduced histological signs of IVD degeneration.

The rationale behind intradiscal O2-O3 therapy is the pain elicited by the mechanical compression of the nerve root, which is associated with periganglionic and periradicular inflammation. This study aimed to determine the effect of intradiscal ozone injection on pain score and satisfaction of patients with low back pain (LBP) secondary to disc herniation. Patients with LBP diagnosed with disc herniation were enrolled in this clinical trial. After prepping and draping the area, intradiscal injection of ozone/oxygen mixture (10 ml, 25µg/ml) was performed under fluoroscopy guide (c-arm). Pain score and patient satisfaction were assessed prior to the injection (baseline) and 1, 3, 6, 12 and 24 months after the injection. Sixty three patients (24 males, 39 females) with mean age of 53.3 ±2.0 y enrolled in the study. The mean±standard deviation (SD) of pain score before intervention was 6.968 ±0.11. Pain score was reduced to 4.25±0.19 at 1 month, 4.33±0.20 at 3 months, 4.87 ±0.21 at 6 months and 5.22 ±0.20 at 24 months. According to the modified MacNab scale success of pain relief was as follows: excellent: 4 (6.3%), good: 17 (26.98 %), sufficient: 13 (20.63 %), poor: 13 (20.63 %), no result: 11 (17.46%), negative: 4 (6.3 %). Intradiscal ozone therapy was determined to provide improved outcomes in patients with single level of bulging and protrusion.

Lower back pain (LBP) is the most common disease in orthopedic clinics world-wide. A classic Fangji of traditional Chinese medicine, Duhuo Jisheng Decoction (DHJSD), has been proven clinically effective for LBP but its therapeutic mechanisms remain unclear. We hypothesized that DHJSD might relieve LBP through inhibiting the exaggerated proinflammatory cytokines and extracellular matrix (ECM) degradation. Thus, we studied the effects of DHJSD on stromal cell-derived factor-1 (SDF-1)-induced inflammation and ECM degradation in human nucleus pulposus cells (hNPCs). The primary hNPCs were isolated from either degenerated human intervertebral disc (HID) of LBP patients or normal HID of lumbar vertebral fracture patients, and cultured in vitro. The cells were treated with SDF-1 (10 ng/mL) and subsequently with different concentrations (100-500 µg/mL) of DHJSD for 24 h, respectively. We found that application of DHJSD significantly antagonized the SDF-1-induced production of proinflammatory cytokines and reduction of aggrecan and type II collagen in the hNPCs. DHJSD also markedly reduced the SDF-1-induced increase of CXCR4 and p-p65 and inhibited the nuclear translocation of p65 in the hNPCs. DHJSD, CXCR4-siRNA, and NF-κB inhibitor (BAY11-7082) caused the same inhibition of exaggerated proinflammatory cytokines in the SDF-1-treated hNPCs. These results provided compelling evidence that DHJSD may inhibit the generation of proinflammatory mediators and ECM degradation of HID through an orchestrated targeting at multiple molecules in the SDF-1/CXCR4/NF-κB pathway, thus offered novel mechanistic insights into the clinical effectiveness of DHJSD on LBP.

Prolotherapy has focused on entheses as a key source of chronic low back pain, even without clear diagnosis of enthesopathy. Treatment has traditionally been guided by anatomic knowledge and careful palpation. This article integrates ultrasonographic diagnosis of fascial injury with examination findings taught in traditional prolotherapy technique. Thoracolumbar fascial anatomy and biotensegrity theory are used to explain patient presentation and response to treatment at these pathologic findings. Detailed case reports provide proof of concept for the 60-year history of prolotherapy in the treatment of chronic low back pain.

BACKGROUND: Adipose tissue-derived mesenchymal stem cells (AT-MSCs) offer potential as a therapeutic option for chronic discogenic low back pain (LBP) because of their immunomodulatory functions and capacity for cartilage differentiation. The goal of this study was to assess the safety and tolerability of a single intradiscal implantation of combined AT-MSCs and hyaluronic acid (HA) derivative in patients with chronic discogenic LBP. METHODS: We performed a single-arm phase I clinical trial with a 12-month follow-up and enrolled 10 eligible chronic LBP patients. Chronic LBP had lasted for more than 3 months with a minimum intensity of 4/10 on a visual analogue scale (VAS) and disability level ≥ 30% on the Oswestry Disability Index (ODI). The 10 patients underwent a single intradiscal injection of combined HA derivative and AT-MSCs at a dose of 2 × 107 cells/disc (n = 5) or 4 × 107 cells/disc (n = 5). Safety and treatment outcomes were evaluated by assessing VAS, ODI, Short Form-36 (SF-36), and imaging (lumbar spine X-ray imaging and MRI) at regular intervals over 1 year. RESULTS: No patients were lost at any point during the 1-year clinical study. We observed no procedure or stem cell-related adverse events or serious adverse events during the 1-year follow-up period. VAS, ODI, and SF-36 scores significantly improved in both groups receiving both low (cases 2, 4, and 5) and high (cases 7, 8, and 9) cell doses, and did not differ significantly between the two groups. Among six patients who achieved significant improvement in VAS, ODI, and SF-36, three patients (cases 4, 8, and 9) were determined to have increased water content based on an increased apparent diffusion coefficient on diffusion MRI. CONCLUSIONS: Combined implantation of AT-MSCs and HA derivative in chronic discogenic LBP is safe and tolerable. However, the efficacy of combined AT-MSCs and HA should be investigated in a randomized controlled trial in a larger population. TRIAL REGISTRATION: ClinicalTrials.gov NCT02338271 .

Hamstring tightness has been documented not to be related to the pelvic tilt position during static standing posture, but there is limited data on the relationship between hamstring muscle length (HML) and pelvic tilt range (PTR) during the dynamic movement of forward bending. This ex-post facto study was designed to compare each of HML and PTR in individuals with low back pain (LBP) and counterparts without LBP, and the relationship between HML and PTR in individuals with and without LBP. The study involved 30 purposively recruited individuals with LBP and 30 height and weight-matched individuals without LBP. Participants' PTR and HML were assessed using digital inclinometer and active knee extension test respectively. Data were analyzed using t-test and Pearson Correlation (r) at α = 0.05. Participants without LBP had significantly longer (p = 0.01) HML than those with LBP but the PTR of both groups were not significantly different. HML and PTR had indirect but not significant correlations in participants with and without LBP. Hamstring muscle length is significantly reduced in individuals with LBP but it has no significant correlation with pelvic tilt range. Pelvic tilt range reduces as hamstring muscle length increases.

BACKGROUND The present study aimed at determining whether 12 weeks of yoga practice in patients with chronic LBP and MRI-based degenerative changes would result in differences in: (i) self-reported pain, anxiety, and spinal flexibility; and (ii) the structure of the discs or vertebrae. MATERIAL AND METHODS Sixty-two persons with MRI-proven degenerative intervertebral discs (group mean ±S.D., 36.2±6.4 years; 30 females) were randomly assigned to yoga and control groups. However, testing was conducted on only 40 subjects, so only their data are included in this study. The assessments were: self-reported pain, state anxiety, spinal flexibility, and MRI of the lumbosacral spine, performed using a 1.5 Tesla system with a spinal surface column. The yoga group was taught light exercises, physical postures, breathing techniques, and yoga relaxation techniques for 1 hour daily for 3 months. No intervention was given to the control group except for routine medical care. A repeated-measures analysis of variance (ANOVA) with post hoc analyses (which was Bonferroni-adjusted) was used. The Ethics Committee of Patanjali Research Foundation had approved the study which had been registered in the Clinical Trials Registry of India (CTRI/2012/11/003094). RESULTS The yoga group showed a significant reduction in self-reported pain and state anxiety in a before/after comparison at 12 weeks. A few patients in both groups showed changes in the discs and vertebrae at post-intervention assessment. CONCLUSIONS Within 12 weeks, yoga practice reduced pain and state anxiety but did not alter MRI-proven changes in the intervertebral discs and in the vertebrae.

BACKGROUND: Over half the population of the world will suffer from moderate or severe low back pain (LBP) during their life span. Studies have shown that naringin, a major flavonoid in grapefruit and an active compound extracted from a Chinese herbal medicine (Rhizoma Drynariae) possesses many pharmacological effects. PURPOSE: The aim of this study was to evaluate the influence of naringin on the growth of degenerative human nucleus pulposus (NP) cells, and its repair effects on protein and gene expressions of the cells. STUDY DESIGN/SETTING: This was an in vitro investigation of the human NP cells isolated from degenerated intervertebral discs that were interacted with various concentrated of naringin. METHOD: This study was exempted by the institutional Human Subjects Committee-2, University of Kansas School of Medicine-Wichita. Degenerative human NP cells were isolated from intervertebral discs of patients with discogenic LBP and cultured at 37°C with 5% CO2. The proliferation of NP cells was determined following treatment with various concentrations of naringin. The protein expressions of tumor necrosis factor-α (TNF-α) and Bone morphogenetic protein 2 (BMP-2) were tested using enzyme-linked immunosorbent assay. Aggrecan and type II collagen levels were measured by immunohistological staining. Further examination of the gene expression of aggrecan, Sox6, and MMP3 was performed after intervention with naringin for 3 days. RESULTS: The human NP cells were successfully propagated in culture and stained positive with toluidine blue staining. Naringin effectively enhanced the cell proliferation at an optimal concentration of 20 µg/mL. Naringin treatment resulted in significant inhibition of TNF-α, but elevated protein expressions of BMP-2, collagen II, and aggrecan. Naringin also increased disc matrix gene activity including aggrecan and Sox6, and decreased the gene expression of MMP3. CONCLUSION: Naringin effectively promotes the proliferation of degenerative human NP cells and improves the recuperation of the cells from degeneration by increasing expression of aggrecan, BMP-2, and Sox6 while inhibiting the expression of TNF-α and MMP3. This study suggests that naringin may represent an alternative therapeutic agent for disc degeneration.

OBJECTIVE: The purpose of this study was to evaluate whether specific MRI features, such as axial location and type of herniation, are associated with outcomes of symptomatic lumbar disc herniation patients treated with spinal manipulation therapy (SMT). METHODS: MRI and treatment outcome data from 68 patients were included in this prospective outcomes study. Pain numerical rating scale (NRS) and Oswestry physical disability questionnaire (OPDQ) levels were measured at baseline. The Patients Global Impression of Change scale, the NRS and the OPDQ were collected at 2 weeks, 1, 3, 6 months and 1 year. One radiologist and 2 chiropractic medicine master's degree students analyzed the MRI scans blinded to treatment outcomes. κ statistics assessed inter-rater reliability of MRI diagnosis. The proportion of patients reporting relevant improvement at each time point was compared based on MRI findings using the chi-square test. The t test and ANOVA compared the NRS and OPDQ change scores between patients with various MRI abnormalities. RESULTS: A higher proportion of patients with disc sequestration reported relevant improvement at each time point but this did not quite reach statistical significance. Patients with disc sequestration had significantly higher reduction in leg pain at 1 month compared to those with extrusion (P = .02). Reliability of MRI diagnosis ranged from substantial to perfect (K = .733-1.0). CONCLUSIONS: Patients with sequestered herniations treated with SMT to the level of herniation reported significantly higher levels of leg pain reduction at 1 month and a higher proportion reported improvement at all data collection time points but this did not reach statistical significance.

OBJECTIVE: Understanding the changes in muscle fiber typing is relevant in the context of muscle disorders because it provides information on the metabolic profile and functional capacity. The aim of this study was to systematically review the literature comparing muscle fiber typing in the back muscles of healthy subjects with low back pain (LBP) patients. METHODS: Predefined keywords regarding muscle fiber typing and back muscles were combined in PubMed and Web of Science electronic search engines from inception to August 2014. Full-text articles were independently screened by 2 independent, blinded researchers. Full texts fulfilling the predefined inclusion criteria were assessed on risk of bias by 2 independent researchers, and relative data were extracted. Data were not pooled because of heterogeneity in biopsy locations and population. RESULTS: From the 214 articles that were identified, 18 met the inclusion criteria. These articles evaluated the muscle fiber type distribution or proportional fiber type area between muscles, muscle layers, men, and women or healthy subjects and LBP patients. Regarding muscle fiber type distribution, findings in healthy subjects and LBP patients show no or inconclusive evidence for intermuscular and interindividual differentiation. Studies evaluating the proportional fiber type area also suggest little intermuscular differentiation but provide plausible evidence that the proportional area occupied by type I fibers is higher in women compared to men. The evidence for differentiation based on the presence of low back pain is conflicting. CONCLUSION: This study found that the evidence regarding muscle fiber typing in back muscles is either inconclusive or shows little differences. The most plausible evidence exists for differentiation in proportional fiber type area depending on sex.

A retrospective case series of three patients with chronic low back pain who received baseline MRI scans revealing multifidus muscle atrophy with fatty replacement is provided. Each patient received spinal manipulative therapy, and two were compliant with low back exercises targeting the multifidus. A follow-up scan performed >1 year later was compared to the baseline scan revealing a decrease in atrophy with fatty replacement in the two patients who performed multifidus-focused low back exercises (15% and 39% on the left and 7% and 32% on the right respectively), and an increase in the patient who underwent spinal manipulation alone (41% and 53%). Interestingly, the decrease in atrophy in the two patients that performed the exercises correlated to functional improvements. Though limited, these results highlight the utility of MRI in quantifying positive and negative long-term changes in multifidus atrophy, which may be an indicator of recovery in chronic low back pain patients.

The medical literature continues to fail to support the use of lumbar epidural injections for long-term relief of chronic back pain without radiculopathy. There is limited support for the use of lumbar epidural injections for shortterm relief in selected patients with chronic back pain. Lumbar intraarticular facet injections are not recommended for the treatment of chronic lower-back pain. The literature does suggest the use of lumbar medial nerve blocks for short-term relief of facet-mediated chronic lower-back pain without radiculopathy. Lumbar medial nerve ablation is suggested for 3-6 months of relief for chronic lower-back pain without radiculopathy. Diagnostic medial nerve blocks by the double-injection technique with an 80% improvement threshold are an option to predict a favorable response to medial nerve ablation for facet-mediated chronic lower-back pain without radiculopathy, but there is no evidence to support the use of diagnostic medial nerve blocks to predict the outcomes in these same patients with lumbar fusion. There is insufficient evidence to support or refute the use of trigger point injections for chronic lowerback pain without radiculopathy.

INTRODUCTION: Low back pain is one of the most common causes of seeking medical attention in industrialized western countries. End plate degenerative changes in the acute phase, formally referred to as Modic type I, represent a specific cause. The aim of this study is to evaluate the effectiveness of vertebral augmentation with calcium sulfate and hydroxyapatite resorbable cement in patients with low back pain resistant to conservative treatment whose origin can be recognized in Modic type I changes. METHODS: From February 2009 to October 2013, 1,124 patients with low back pain without radicular symptoms underwent physical and imaging evaluation. Stringent inclusion criteria elected 218 to vertebral augmentation with resorbable cement. Follow-up period was 1 year. RESULTS: One hundred seventy-two (79 %) patients improved quickly during the first 4 weeks after treatment. Forty-two (19 %) patients showed a more gradual improvement over the first 6 months, and at 1 year, their pain level did not differ from that of the previous group. In both groups, pain did not resolved completely, but patients showed significant improvement in their daily life activities. Two (1 %) patients did not show any improvement. Two (1 %) patients died for other reasons. There were no complications related to the procedures. CONCLUSION: Vertebroplasty with bioactive resorbable bone cement seems to be an effective therapeutic option for patients with low back pain resistant to conservative treatment whose origin could be recognized in Modic type I end plate degenerative changes.

CONTEXT: Individuals with low back pain (LBP) have reduced function of the transversus abdominis (TrA) and lumbar multifidus (LM) muscles. Biofeedback during exercise may increase the ability to contract the TrA and LM muscles compared with exercise alone. OBJECTIVE: To compare TrA preferential activation ratio (PAR) and the percent change in LM-muscle thickness in patients with LBP history before and after exercise with or without biofeedback. DESIGN: Controlled laboratory study. SETTING: University research laboratory. PATIENTS: 20 LBP individuals, 10 exercise alone and 10 exercise with biofeedback. INTERVENTIONS: Patients were allotted to tabletop exercises in isolation or tabletop exercises with visual, auditory, and tactile biofeedback. MAIN OUTCOME MEASURES: TrA PAR and percent change in LM-muscle thickness. RESULTS: There were no differences between groups at baseline (all P > .05). Nonparametric statistics showed decreased resting muscle thickness for total lateral abdominal-wall muscles (P = .007) but not TrA (P = .410) or LM (P = .173). Percent TrA thickness increased from table to standing positions before (P = .006) and after exercise (P = .009). TrA PAR increased after exercise (pre 0.01 ± 0.02, post 0.03 ± 0.04, P = .033) for all patients and for exercise with biofeedback (pre 0.02 ± 0.01, post 0.03 ± 0.01, P = .037) but not for exercise alone (pre 0.01 ± 0.02, post 0.02 ± 0.05, P = .241). No group differences were observed for TrA PAR before (exercise 0.01 ± 0.02, exercise with biofeedback 0.02 ± 0.01, P = .290) or after exercise (exercise 0.02 ± 0.05, exercise with biofeedback 0.03 ± 0.01, P = .174). There were no group differences in LM percent change before exercise (P = .999) or after exercise (P = .597). In addition, no changes were observed in LM percent change as a result of exercise among all participants (P = .391) or for each group (exercise P = .508, exercise with biofeedback P = .575). CONCLUSION: TrA PAR increased after a single session of exercises, whereas no thickness changes occurred in LM.

OBJECTIVE: To update evidence-based clinical practice guidelines (EBCPG) on massage therapy compared to control or other treatment for adults (>18 years) suffering from acute, sub-acute and chronic low back pain (LBP). METHODS: A literature search was performed for relevant articles between January 1, 1948 and December 31, 2010. Eligibility criteria were then applied focussing on participants, interventions, controls, and outcomes, as well as methodological quality. Recommendations based on this evidence were then assigned a grade (A, B, C, C+, D, D+, D-) based on their strength. RESULTS: A total of 100 recommendations were formulated from 11 eligible articles, including 37 positive recommendations (25 grade A and 12 grade C+) and 63 neutral recommendations (49 grade C, 12 grade D, and 2 grade D+). DISCUSSION: These guidelines indicate that massage therapy is effective at providing pain relief and improving functional status. CONCLUSION: The Ottawa Panel was able to demonstrate that massage interventions are effective to provide short term improvement of sub-acute and chronic LBP symptoms and decreasing disability at immediate post treatment and short term relief when massage therapy is combined with therapeutic exercise and education.

The objective of the present study was the dynamic estimation of the intensity of pain syndrome with the use of a visual-analog scale (VAS), characteristics of the psychological status and cognitive disorders, quality of life, and brain electrogenesis in 50 patients presenting with vertebrogenic pain syndrome of lumbar-sacral localization. It was shown that long-standing pain syndrome plays the dysadaptive role, causes structural and functional changes in the central nervous system (CNS), and is responsible for psychoemotional and cognitive disorders. The introduction of transcranial stimulation in the combined treatment of such patients promotes correction and reversibility of the above disorders, enhances the efficacy of electrotherapy, and improves the quality of life in the subjects with vertebrogenic pain syndrome.

Psoas syndrome is an easily missed diagnosis. However, it is important to consider this condition as part of the differential diagnosis for patients presenting with low back pain--particularly for osteopathic physicians, because patients may view these practitioners as experts in musculoskeletal conditions. The authors describe the case of a 48-year-old man with a 6-month history of low back pain that had been attributed to "weak core muscles." The diagnosis of psoas syndrome was initially overlooked in this patient. After the correct diagnosis was made, he was treated by an osteopathic physician using osteopathic manipulative treatment, in conjunction with at-home stretches between office treatments. At his 1-month follow-up appointment, he demonstrated continued improvement of symptoms and a desire for further osteopathic manipulative treatment.
