Efficacy of Electroacupuncture Combined with Chinese Herbal Medicine on Pain Intensity for Chronic Sciatica Secondary to Lumbar Disc Herniation: Study Protocol for a Randomised Controlled Trial.

Purpose: Chinese herbal medicine and electroacupuncture (EA) have been used to control pain for many decades in China. We aim to explore the efficacy of intervening patients whose discogenic sciatica symptoms lasting longer than 3 months with these conservative treatments. Patients and Methods: This is a single-center, parallel-group, patient-unblinded Randomized Controlled Trial (RCT) with blinded outcome assessment and statistician. One hundred and twenty-four patients will be assigned randomly into 2 groups including conservative treatment group (Shenxie Zhitong capsule combined with EA treatment) and Nonsteroidal Anti-inflammatory Drugs (Nonsteroidal Anti-inflammatory Drugs, NSAIDs) control group (Celecoxib) in a 1:1 ratio. The trial involves a 4-week treatment along with follow-up for 6 months. The primary outcome is the leg pain intensity measured by the visual analogue scale (VAS) at 6 months after randomization. Secondary outcomes include leg pain intensity at other time points, back pain intensity, leg pain and back pain frequency, functional status, quality of life, return to work status and satisfaction of patients. Adverse events will also be recorded. Strengths and Limitations of This Study: Through this study, we want to observe the efficacy of electroacupuncture combined with Chinese herbal medicine on pain intensity for chronic sciatica secondary to Lumbar Disc Herniation. If the final results are favorable, it is expected to be a safe, economical, and effective treatment for patients. The study design has the following limitations: the setup of control group was less than perfect; patients and doctors could not be blinded in this trial; we skipped the feasibility study. We have tried our best to minimize adverse impacts. Trial Registration: ChiCTR2300070884 (Chinese Clinical Trial Registry, http://www.chictr.org.cn, registered on 25th April 2023).

OBJECTIVES: To observe the body surface temperature of the lumbosacral region and relevant back-shu points in patients with lumbar disc herniation (LDH) induced low back pain utilizing infrared thermography, and to explore the functional attribute changes of acupoints under pathological conditions. METHODS: A total of 50 patients with LDH induced low back pain were included as the observation group, and 45 healthy subjects were included as the control group. Using infrared thermography, the body surface temperature of the lumbosacral region and bilateral Sanjiaoshu (BL 22), Shenshu (BL 23), Qihaishu (BL 24), Dachangshu (BL 25), Guanyuanshu (BL 26), Xiaochangshu (BL 27), and Pangguangshu (BL 28) was measured in both groups. The temperature difference values between the bilateral lumbosacral regions and back-shu points of the two groups were calculated. Additionally, the body surface temperature of the affected and healthy sides of the lumbosacral region and relevant back-shu points was compared in the observation group. RESULTS: Compared with the control group, the body surface temperature of the lumbosacral region and the bilateral temperature difference values of the lumbosacral regions were increased in the observation group (P<0.001). The body surface temperature difference values of bilateral Shenshu (BL 23), Qihaishu (BL 24), Dachangshu (BL 25), Guanyuanshu (BL 26) and Xiaochangshu (BL 27) in the observation group were higher than those in the control group (P<0.05, P<0.01, P<0.001). In the observation group, the body surface temperature of the affected side of the lumbosacral region as well as Shenshu (BL 23) and Dachangshu (BL 25) was elevated compared with that of healthy side (P<0.001). CONCLUSIONS: The patients with LDH induced low back pain have imbalanced and asymmetrical distribution of body surface temperature in the lumbosacral region and related back-shu points, Shenshu (BL 23) and Dachangshu (BL 25) have the relative specificity.

An evidence-based guideline on treating lumbar disc herniation with traditional Chinese medicine.

BACKGROUND: Lumbar disc herniation (LDH), as one of the most common causes of lower back pain, imposes a heavy economic burden on patients and society. Conservative management is the first-line choice for the majority of LDH patients. Traditional Chinese medicine (TCM) is an important part of conservative treatment and has attracted more and more international attention. STUDY DESIGN: Evidence-based guideline. METHODS: We formed a guideline panel of multidisciplinary experts. The clinical questions were identified on the basis of a systematic literature search and a consensus meeting. We searched the literature for direct evidence on the management of LDH and assessed its certainty-generated recommendations using the grading of recommendations, assessment, development, and evaluation (GRADE) approach. RESULTS: The guideline panel made 20 recommendations, which covered the use of Shentong Zhuyu decoction, Shenzhuo decoction, Simiao San decoction, Duhuo Jisheng decoction, Yaobitong capsule, Yaotongning capsule, Osteoking, manual therapy, needle knife, manual acupuncture, electroacupuncture, Chinese exercise techniques (Tai Chi, Baduanjin, or Yijinjing), and integrative medicine, such as combined non-steroidal anti-inflammatory drugs, neural nutrition, and traction. Recommendations were either strong or weak, or in the form of ungraded consensus-based statement. CONCLUSION: This is the first LDH treatment guideline for TCM and integrative medicine with a systematic search, synthesis of evidence, and using the GRADE method to rate the quality of evidence. We hope these recommendations can help support healthcare workers caring for LDH patients.

Non-Surgical Approaches to the Management of Lumbar Disc Herniation Associated with Radiculopathy: A Narrative Review.

Lumbar disc herniation associated with radiculopathy (LDHR) is among the most frequent causes of spine-related disorders. This condition is triggered by irritation of the nerve root caused by a herniated disc. Many non-surgical and surgical approaches are available for managing this prevalent disorder. Non-surgical treatment approaches are considered the preferred initial management methods as they are proven to be efficient in reducing both pain and disability in the absence of any red flags. The methodology employed in this review involves an extensive exploration of recent clinical research, focusing on various non-surgical approaches for LDHR. By exploring the effectiveness and patient-related outcomes of various conservative approaches, including physical therapy modalities and alternative therapies, therapists gain valuable insights that can inform clinical decision-making, ultimately contributing to enhanced patient care and improved outcomes in the treatment of LDHR. The objective of this article is to introduce advanced and new treatment techniques, supplementing existing knowledge on various conservative treatments. It provides a comprehensive overview of the current therapeutic landscape, thereby suggesting pathways for future research to fill the gaps in knowledge. Specific to our detailed review, we identified the following interventions to yield moderate evidence (Level B) of effectiveness for the conservative treatment of LDHR: patient education and self-management, McKenzie method, mobilization and manipulation, exercise therapy, traction (short-term outcomes), neural mobilization, and epidural injections. Two interventions were identified to have weak evidence of effectiveness (Level C): traction for long-term outcomes and dry needling. Three interventions were identified to have conflicting or no evidence (Level D) of effectiveness: electro-diagnostic-based management, laser and ultrasound, and electrotherapy.

Warm Acupuncture Reduces Pain and Inflammation in Rats with Lumbar Disc Herniation Induced by Autologous Nucleus Pulposus Transplantation via Regulating p38MAPK/NF-κB Pathway.

Background: : Warm acupuncture (WA) has analgesic and anti-inflammatory effects. However, the underlying mechanism of these effects remain unclear. Objectives: : To explore the analgesic and anti-inflammatory effects of WA and the potential underlying mechanism in male Sprague-Dawley rats with non-compressive lumbar disk herniation (LDH) caused by autologous nucleus pulposus (NP) transplantation. Methods: : We used low-frequency (2 Hz) electrical stimulation and WA (40℃) to treat GB30 and BL54 acupoints in rats for 30 mins per day. We monitored the paw withdrawal threshold of rats during the experiment and measured serum cytokine levels using commercial kits. Dorsal root ganglion (DRG) tissue pathology was analyzed via H&E staining. We used qRT-PCR to measure the mRNA expression levels of IL-1ß, IL-6, and TNF-α genes in DRG. Western blot was used to analyze the expression levels of IL-1ß, IL-6, TNFα, P-p38MAPK, p38MAPK, P-IκBα, IκB α, and NF-κB p65 proteins. Results: : WA treatment significantly increased the pain threshold of rats, reduced serum IL-6, PEG2, NO, SP, NP-Y, and MMP-3 levels, and effected histopathological improvements in the DRG in rats. Moreover, WA treatment significantly downregulated the expression levels of inflammation-associated genes (Il-1ß, Il-6, and Tnf-α) and proteins (IL-1ß, IL-6, TNF-α, P-p38MAPK, P-IκBα, and NF-κB p65) in the DRG of non-compressive LDH rats. Conclusion: : WA can alleviate pain and inhibit inflammatory response in rats with non-compressive LDH caused by autologous NP transplantation, and these effects are likely associated with the inhibition of the p38MAPK/NF-κB pathway.

Chiropractic Management of Lumbar Disc Herniation in a Patient With Co-existing Liver Cancer: A Case Report.

The current case report outlines the chiropractic management of a 30-year-old male construction worker who presented with symptoms of lumbar disc herniation with co-existing stage IV liver cancer. The patient reported experiencing substantial lower back pain and decreased sensation in his right leg following a fall at work, impacting his mobility and quality of life. The complexity of this case is underscored by the challenge of differentiating between pain due to metastatic disease and that related to the fall. The chiropractic treatment plan included gentle joint mobilization, instrument-assisted soft tissue mobilization, and low-impact exercises tailored to the patient's overall health status. The treatment protocol markedly improved pain levels, range of motion, and overall quality of life. This case highlights the potential role of chiropractic care in managing complex cases of lumbar disc herniation, even in the presence of severe illnesses such as liver cancer. This study provides valuable insights into the importance of personalized and adaptable treatment strategies in managing such cases, contributing a unique perspective to the scientific literature.

Mechanism exploration of Osteoking in the treatment of lumbar disc herniation based on network pharmacology and molecular docking.

OBJECTIVE: Lumbar disc herniation (LDH) is a common spinal surgical disease. Low back and leg pain caused by LDH is the main factor leading to functional disability, which has caused a serious burden to patients and society. Osteoking can delay the progression of osteoporosis and osteoarthritis, and even has a significant effect on the prevention of deep vein thrombosis after fracture surgery. In recent years, it has been gradually used in the treatment of LDH and has received significant results. However, the underlying mechanism remains unclear. The aim of this study was to predict the mechanism of Osteoking in the treatment of LDH through network pharmacology and verify it by molecular docking method. METHODS: The TCMSP database was used to collect the relevant active components and targets of Osteoking, while the GeneCards, OMIM and DisGeNET databases were utilized to collect the relevant disease targets of LDH. The Venny 2.1.0 software was employed to obtain the intersecting gene targets of Osteoking and LDH. PPI network construction and core target selection were performed using Cytoscape 3.9.0 software. The Metascape database was used for GO and KEGG enrichment analysis of the relevant targets. Finally, molecular docking was conducted using AutoDock software. RESULTS: The study identified 116 potential targets and 26 core targets for the treatment of LDH with Osteoking. Pathways in cancer, Alzheimer's disease, microRNAs in cancer and the IL-17 signalling pathway were among the main involved signalling pathways. Molecular docking results demonstrated that the key targets AKT1, IL-6, ALB, TNF and IL-1ß exhibited relatively stable binding activities with the main active components of Osteoking. CONCLUSIONS: Osteoking can alleviate the symptoms of lumbar disc herniation through the modulation of multiple targets and signalling pathways.

Evaluation of the efficacy and safety of percutaneous transforaminal endoscopic discectomy for multi-segmental lumbar disc herniation.

Objective: To investigate the clinical efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of multi-segmental lumbar disc herniation (msLDH). Methods: From January 2021 to December 2021, 75 patients with msLDH admitted to Baoding No.1 Hospital of Traditional Chinese Medicine were selected and divided into PTED group (n=40) and posterior lumbar interbody fusion (PLIF) group (n=35) according to different surgical methods. The operative time, intraoperative blood loss, surgical complications, Oswestry disability index (ODI) and Japanese Orthopedic Association score (JOA) scores were compared between the two groups. Results: In the PTED group, the average operation time was 57.45±12.01minutes, and the average intraoperative blood loss was 50.57±16.69ml. There were three patients with surgical complications, including one case of hematoma, one case of aggravation of neurological symptoms and one case of new onset of neurological symptoms. In the PLIF group, there were 12 cases undergoing single-segment operation, 15 cases undergoing double-segment operation and 8 cases undergoing three-segment operation, the average operation time was 137.26±34.64minutes, and the average intraoperative blood loss was 456.06±33.06ml, there were four cases of wound fat liquefaction or delayed healing, two cases of hematoma, and three cases of exacerbation of original neurological symptoms or new neurological symptoms. At one month, six months, and one year of postoperative, the ODI and JOA scores of the two groups were significantly improved compared with those preoperative, and the ODI scores of the PTED group were better than those of the PLIF group (t=3.131, 2.263, 3.768, all P<0.05). Conclusion: The surgical effect of PTED in the treatment of LDH is similar to that of PLIF. However, PTED has the advantages of short operation time, less blood loss, fewer surgical complications, and high surgical safety. It is worthy of clinical promotion.

Complete resolution of lumbar disc sequestration with Ayurveda management: A case report.

Lumbar disc herniation (LDH) is the most common spinal disorder among which disc sequestration is a severe type where the herniated disc fragment migrates and is completely separated from the parent disc. A 46-year-old female patient with severe lower back pain radiating to right lower limb, disability, and numbness in the affected extremity came to Panchakarma O.P.D of our hospital. She was a chronic case of disc sequestration where her symptoms were severely aggravated after a sudden jolt felt on her lower back while traveling on a motorcycle. The patient's Oswestry disability index (ODI) score was 90 % which indicates a bed-bound condition and even Schobar's test indicated a severe reduction in lumbar flexion capability. MRI showed postero-central herniation with disc sequestration at L5-S1 caused compression on the subarachnoid space and traversing S1 nerve roots. She was treated according to Ayurveda treatment principles and underwent Panchakarma like medicated enema (Basti) and fomentation of a lumbosacral region with oil (Kati Basti). She also received different oral medications on successive follow-ups. After 6 months of Ayurveda treatment, the patient showed remission in lower back pain (LBP), radiculopathy, and numbness. Her ODI score was reduced to 6 %. The MRI repeated post-treatment showed complete interval resolution of disc sequestration and no neurological compression was observed.

N-Acetyl Cysteine as an Add-on Therapy is Useful in Treating Acute Lumbar Radiculopathy Caused by Disc Herniation: Results of a Randomized, Controlled Clinical Trial.

BACKGROUND: Available experimental and clinical evidence indicates that N-Acetyl cysteine (NAC) may have an analgesic role in specific pain conditions, particularly neuropathic pain. Thus, we hypothesized that NAC supplementation might be also helpful in decreasing pain and improving pain-related disability in patients with acute radiculopathy. We designed this study to investigate the potential use of NAC-adjunctive treatment to Nonsteroidal Anti- Inflammatory Drugs (NSAIDs) in patients with acute radiculopathy secondary to lumbar intervertebral disc herniation. METHODS: Sixty-two patients diagnosed with acute lumbar radiculopathy associated with disc herniation were randomly allocated to the NAC or the placebo groups. Besides naproxen at a dose of 500 mg twice a day, participants based on their allocation group started with NAC or matched placebo at a dose of 600 mg twice a day for eight weeks. The pain severity, measured by the Visual Analog Scale (VAS), and pain-related disability measured by the Oswestry Disability Index (ODI) were measured at baseline and weeks 2, 4, and 8 of treatment. Global improvement of symptoms rated by Patient and Clinical Global Impressions of Change (PGIC and CGIC) was also recorded at the end of week 8. All analyses were conducted on an Intentionto- Treat (ITT) analysis data set. RESULTS: A comparison of the VAS and ODI scores at weeks 2 and 4 of the treatment between the two groups did not show a significant difference. In contrast, from week 4 to week 8, we noticed a significantly greater reduction in the mean VAS and ODI scores in the NAC group compared to the placebo group (p-value <0.001 for both variables). In parallel with these results, also, more NAC-treated than placebo-treated patients achieved treatment success defined as ''very much'' or ''much improved'' on CGIC and PGIC scales, and these differences reached a significant level (p-value = .011 and p-value = .043). CONCLUSIONS: This study suggested that NAC might be a relevant candidate for adjunct therapy in managing acute lumbar radiculopathy. Additional clinical trials are needed to validate these findings.

An L2/3 Disc Herniation-Related L5 Radiculopathy.

The key factors contributing to radiculopathy caused by lumbar disc herniation include mechanical compression. It was commonly believed that the disc herniation causes the compression on the nerve root exiting under the pedicle of the vertebral body at the adjacent inferior level. However, a disc herniation might occasionally result in non-adjacent, isolated radicular symptoms. We report the case of a 74-year-old female who presented with a 2-years history of progressive low back pain associated with L5 radiculopathy and reduced quality of life. The patient had undergone a magnetic resonance image showing a large L2/3 disc herniation. Symptoms had progressively worsened and failed to respond to conservative treatments including pain medication, exercise rehabilitation, and acupuncture at the lower lumbar region. The patient was diagnosed with L5 radiculopathy caused by L2/3 disc herniation. Consequently, her symptoms improved with chiropractic rehabilitation which involved spinal manipulative therapy and intermittent motorized traction at the L2/3 level to reduce herniated disc. Therefore, an L2/3 Disc herniation-related L5 radiculopathy should be considered in the differential diagnosis of cases of inconsistency of level of disc herniation and nerve root pattern.

Zhiqiao Gancao Decoction Ameliorates Hyperalgesia in Lumbar Disc Herniation via the CCL2/CCR2 Signaling Pathway.

Purpose: The aim of this study was to investigate the effect of Zhiqiao Gancao decoction (ZQGCD) on hyperalgesia in lumbar disc herniation (LDH) and its mechanism. Methods: The potential mechanism of ZQGCD's therapeutic effect on LDH was investigated through network pharmacology, which involved screening the targets of eight components that were absorbed into the bloodstream. The effects of CCR2 inhibitors and ZQGCD-containing serum on the excitability of the CCL2/CCR2 signaling pathway and dorsal root ganglion neurons (DRGn) were investigated in vitro. The effects of CCR2 inhibitors and ZQGCD on the expression of the CCL2/CCR2 signaling pathway and ASIC3 in the rat intervertebral disc and dorsal root ganglion (DRG), the degree of disc degeneration, the threshold of foot retreat, and the latency of foot retreat in LDH rats were examined in vivo. The binding affinities and interaction modes between CCR2 and the components absorbed into the blood were analyzed using the AutodockVina 1.2.2 software. Results: Network pharmacology revealed that ZQGCD could treat LDH through a mechanism involving the chemokine signaling pathway. It was observed that the CCR2 inhibitor and ZQGCD-containing serum downregulated CCR2 and ASIC3 expression and decreased cell excitability in DRGn. The CCL2/CCR2 signaling pathway was activated in the degenerated intervertebral disc and DRG of LDH rats, increased the expression of ASIC3, and decreased the mechanical allodynia domain and thermal hyperalgesia domain. However, a CCR2 inhibitor or ZQGCD could ameliorate the above changes in LDH rats. The target proteins, CCL2 and CCR2, exhibited a robust affinity for the eight components that were absorbed into the bloodstream. Conclusion: The CCL2/CCR2 pathway was activated in the intervertebral disc and DRG of LDH rats. This was accompanied by upregulation of ASIC3 expression, increased excitability of DRGn, and the occurrence of hyperalgesia. ZQGCD improves hyperalgesia in LDH rats by inhibiting the CCL2/CCR2 pathway and downregulating ASIC3 expression.

[Effect of acupuncture at "Houxi" (SI3) and"Huantiao" (GB30) on high mobility group box 1 protein in spinal nerve trunk of rats with lumbar disc herniation].

OBJECTIVE: To observe the effect of acupuncture at "Houxi"(SI3) and "Huantiao"(GB30) on high mobility group box 1(HMGB1) protein and mRNA in spinal nerve trunk(SNT) of rats with lumbar disc herniation(LDH), so as to explore the mechanisms of acupuncture at this paired points on the treatment for LDH. METHODS: SD rats were randomly divided into sham operation, model, conventional acupuncture(CA) and paired points(PP) groups (with 8 rats in each group). The LDH model was established by injection of autologous suspension made from rats' own nucleus pulsus into the epidural space. Rats in the CA group received acupuncture treatment at bilateral "Weizhong"(BL40), "Dachangshu"(BL25) and "Shenshu"(BL23), while rats in the PP group received acupuncture at bilateral SI3 and GB30, 30 min each time, once daily for 14 consecutive days. The thermal pain threshold of bilateral hind feet of rats was detected by thermal pain stimulator. The contents of serum IL-1ß, IL-6 and IL-8 of rats were detected by ELISA. Western blot and immunofluorescence were used to detect the expression of HMGB1 protein in the lumbar(L)5 SNT of rats. The relative expression of HMGB1 mRNA in L5 SNT was determined by qPCR. HE staining was used to observe the morphological changes of L5 SNT. RESULTS: Compared with the sham operation group, the thermal pain threshold of bilateral hind feet in the model group was decreased (P<0.05); compared with the model group, the thermal pain threshold of bilateral hind feet in the CA group and the PP group were increased (P<0.05). The expressions of HMGB1 protein and mRNA in L5 SNT, and the contents of serum IL-1ß, IL-6 and IL-8 of rats in the model group were significantly increased(P<0.000 1, P<0.001) in contrast to the sham operation group. The expressions of HMGB1 protein and mRNA in L5 SNT, and the levels of serum IL-1ß, IL-6 and IL-8 were significantly decreased (P<0.01, P<0.000 1, P<0.001, P<0.05) in the CA and PP group, in comparison with those of the model group. Compared with the CA group, the above indexes of rats in the PP group recovered more significantly (P<0.05,P<0.001, P<0.01,P<0.000 1). The histomorphological results showed scattered and various-sized nerve fibers, vacuolation, a large number of disintegrating myelin sheath and lysed Schwann cells in the model group. Myelin sheaths regeneration, regularly-arranged nerve fibers were seen in the CA group and the PP group, with more obvious histopathological recovery observed in the PP group than the CA group. CONCLUSION: Acupuncture intervention inhibites the expressions of HMGB1 protein and mRNA in rats with LDH, and further reduces the production of IL-1ß, IL-6 and IL-8, which is beneficial to inflammatory response inhibition and pain alleviation. The therapeutic effect of the PP group is more obvious than that of the CA group.

Research Trends of the Research and Development of Acupuncture and Moxibustion Therapy on Lumbar Disc Herniation: A Bibliometric Analysis.

Background: Acupuncture and moxibustion has been applied worldwide in the treatment of various pain diseases including lumbar disc herniation (LDH) and other pain, However, there has been no bibliometric analysis on this aspect in the past five years. Therefore, this study was carried out for finding research trends and fronts in this field using Citespace and VOSviewer. Methods: Publications about acupuncture therapy for LDH were extracted from the Web of Science database and PubMed with an unlimited time frame. A bibliometric analysis and visualization of results was conducted using CiteSpace 6.1.R3 and VOSviewer 1.6.18 on the information of the annual publication, countries, journals, institutions, authors, references, and keywords. Results: A total of 127 publications were included, and the number of publications had increased noticeably over the past 30 years and reached a peak in the past 3 years. The most productive country with the most publications was China, whose Medical University was the institution with the highest volume of publications. The most productive author was Chen Rixin, while the most-cited author was Kreiner DS. Chinese Acupuncture and Moxibustion was the journal with the most publications, and Spine Journal was the most frequently cited journal. In cited references, an article published in The New England Journal of Medicine by Deyo RA had the most citations and the highest centrality. Of the keywords, the five most frequently used keywords include lumbar disc herniation, acupuncture, low back pain, intervertebral disc displacement, and management. Conclusion: Acupuncture and moxibustion can help to relieve symptoms in patients. However, this field is in the early stages of development and requires more high-quality research studies and international collaborations. In addition, exploring the effectiveness and mechanism of acupuncture for LDH is the hot trend in the future.

Evaluating the value of progressive muscle relaxation therapy for patients with lumbar disc herniation after surgery based on a difference-in-differences model.

We evaluate the value of progressive muscle relaxation (PMR) for patients with lumbar disc herniation after surgery based on a difference-in-differences model. A total of 128 patients with lumbar disc herniation who underwent surgery were randomly assigned to undergo either conventional intervention (conventional intervention group, n = 64) or conventional intervention combined with PMR (PMR group, n = 64). Perioperative anxiety level, stress level and lumbar function were compared between the two groups and compared pain between the two groups before and 1 week and 1 and 3 months after surgery. After 3 months, no one was lost to follow-up. At 1 day before surgery and 3 days after surgery, Self-rating Anxiety Scale score in the PMR group was significantly lower than that in the conventional intervention group (P < 0.05). At 30 min before surgery, heart rate and systolic blood pressure in the PMR group were significantly lower than those in the conventional intervention group (P < 0.05). After intervention, the scores of subjective symptoms, clinical signs and restrictions on activities of daily living were significantly higher in the PMR group than those in the conventional intervention group (all P < 0.05). Visual Analogue Scale score in the PMR group was significantly lower than that in the conventional intervention group (all P < 0.05). The amplitude of change in VAS score in the PMR group was greater than that in the conventional intervention group (P < 0.05). PMR can relieve perioperative anxiety and stress in patients with lumbar disc herniation, reduce postoperative pain and improve lumbar function.

Traditional Chinese Manual Therapy (Tuina) reshape the function of default mode network in patients with lumbar disc herniation.

Purpose: Investigating the changes of regional homogeneity (ReHo) values and both static and dynamic functional connectivity (FC) before and after Traditional Chinese Manual Therapy (Tuina) in patients with lumbar disk herniation (LDH) through resting-state functional magnetic resonance imaging (RS-fMRI). Based on this, we observe the effect of Tuina on the above abnormal changes. Methods: Patients with LDH (n = 27) and healthy controls (HCs) (n = 28) were recruited. The functional magnetic resonance imaging (fMRI) scanning was performed two times in LDH patients, before Tuina (time point 1, LDH-pre) and after the sixth Tuina (time point 2, LDH-pos). And for one time in HCs which received no intervention. The ReHo values were compared between LDH-pre and HCs. The significant clusters detected by ReHo analysis were selected as seeds to calculate static functional connectivity (sFC). We also applied the sliding-window to perform dynamic functional connectivity (dFC). To evaluate the Tuina effect, the mean ReHo and FC values (both static and dynamic) were extracted from significant clusters and compared between LDH and HCs. Results: In comparison to HCs, LDH patients displayed decreased ReHo in the left orbital part middle frontal gyrus (LO-MFG). For sFC analysis, no significant difference was found. However, we found decreased dFC variance between LO-MFG and the left Fusiform, and increased dFC variance in the left orbital inferior frontal gyrus and left precuneus. Both ReHo and dFC values revealed after Tuina, the brain activities in LDH patients were similar to HCs. Conclusion: The present study characterized the altered patterns of regional homogeneity in spontaneous brain activity and those of functional connectivity in patients with LDH. Tuina can reshape the function of the default mode network (DMN) in LDH patients, which may contribute to the analgesic effect of Tuina in LDH patients.

A Severe Disc Herniation Mimics Spinal Tumor.

Lumbar disc herniation (LDH) is prevalent among adults aged 25-55 years who spend a considerable proportion of their time sitting or standing with heavy workloads. We report the case of a 33-year-old male waiter with severe LDH, causing compression of the nerve roots and spinal cord with neurological dysfunction, who presented to a chiropractic clinic. Magnetic resonance imaging (MRI) revealed a radiological differential diagnosis comprising LDH and an epidural mass lesion. To rule out serious pathology, a second MRI with contrast was ordered, which confirmed the diagnosis of severe LDH. Diagnosing large LDH may be challenging, and severe disc herniation often mimics spinal tumors. This study offers insights into the differential diagnosis of LDH and spinal tumors, as well as the design of a treatment strategy for severe LDH in the chiropractic clinic.

Independent reliability and availability analyses of modified classification for migrated lumbar disc herniation.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study was to evaluate the reliability of modified classification system of migrated nucleus pulposus and its clinical application value. METHODS: We retrieved 1000 lumbar MRI of different patients in Hangzhou Hospital of Traditional Chinese Medicine from January 2016 to December 2019 for interpretation, and screened 105 migrated lumbar MRI for inclusion in the study. Three spinal surgeons made classification according to the modified classification method. Two weeks later, the sorting data of the patients were shuffled and the classification was judged by three doctors again. The consistency and repeatability of the improved classification were evaluated by Kappa coefficient. The general data of the included patients were collected. The patients were followed up for 2 years, and the risk factors of surgical treatment of patients with migrated lumbar disc herniation were analyzed. The treatment plan, surgical approach, operation time, VAS score, ODI score and other relevant data of the included patients were collected to evaluate the guiding effect of the classification system on clinical practice. RESULTS: In this study, the incidence of migrated lumbar disc herniation was about 10.5%, and most of the patients were male. Patients with higher BMI are more likely to develop this disease. Our study confirmed that the modified classification has moderate to high confidence. During the 2-year follow-up period, 66 patients (62.9%) were treated conservatively, and the patients with conservative treatment were mainly A2 and B2 type (59.1%). Thirty-nine patients (37.1%) underwent surgical treatment. The patients recovered well after operation, and the low back pain and ODI index were significantly improved at 1 year after operation (P < 0.05). We suggest that type A1 and B1 migrated nucleus pulposus can be removed by posterior approach. For type A2, B2, C1, C2, the lateral approach is recommended to remove the nucleus pulposus directly. Logistic regression and ROC analysis showed that disease duration (≥ 1 year) and BMI (≥ 24) maybe were risk factors for surgical treatment of patients with migrated lumbar disc herniation. CONCLUSION: The modified classification has good reliability. In the current study, the experience level of spine surgeons does not affect the reliability of the classification system. Our study confirmed that this classification has a good reference value for guiding the treatment plan and the choice of surgical approach.

[Effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy].

OBJECTIVE: To observe the effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle (LMM) in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy (PTED). METHODS: A total of 104 patients with lumbar disc herniation treated with PTED were randomly divided into an observation group (52 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). Patients of both groups received rehabilitation training of two weeks 48 h after PTED treatment. The observation group was treated with acupotomy (L3-L5 Jiaji [EX-B 2]) once within 24 h after PTED. In the two groups, the fat infiltration cross sectional area (CSA) of LMM was compared before and 6 months after PTED, the visual analogue scale (VAS) score and Oswestry disability index (ODI) score were observed before and 1, 6 months after PTED. The correlation between fat infiltration CSA of LMM in each segment and VAS score was analyzed. RESULTS: Six months after PTED, the fat infiltration CSA of LMM in L4/L5 and the total L3-S1 segments of the observation group was lower than that before PTED (P<0.05), and the fat infiltration CSA of LMM in L4/L5 of the observation group was lower than the control group (P<0.01). One month after PTED, the ODI and VAS scores of the two groups were lower than those before PTED (P<0.01), and those in the observation group were lower than the control group (P<0.05). Six months after PTED, the ODI and VAS scores of the two groups were lower than those before PTED and 1 month after PTED (P<0.01), and those in the observation group were lower than the control group (P<0.01). There was a positive correlation between the fat infiltration CSA of LMM in the total L3-S1 segments and VAS scores in the two groups before PTED (r = 0.64, P<0.01). Six months after PTED, there was no correlation between the fat infiltration CSA of LMM in each segment and VAS scores in the two groups (P>0.05). CONCLUSION: Acupotomy can improve the fat infiltration degree of LMM, pain symptoms and activities of daily living in patients with lumbar disc herniation after PTED.
