Introduction. Low back pain is one of the most frequent causes of consultation and disability in patients, and according to its temporal evolution it can be classified as acute, subacute and chronic. Objective. To estimate the efficacy of an exercise program compared to non-steroidal anti-inflammatory drugs (NSAIDs) in patients with subacute low back pain (LBP). Methods. A randomized, single-masked, controlled clinical trial was conducted in 90 patients and DLS with or without radiculopathy, 46 patients were assigned to a physical exercise program and 44 to NSAID treatment. The primary outcome was improvement in pain and the secondary outcomes were improvement in function, quality of life, work absenteeism and depression with follow-up at 1, 3 and 6 months. Results. At 1 month, there was no difference in pain between groups of 8.16 (95 % CI -2.19 to 18.51), however, in the exercise group there was an improvement from 47.3 (SD: 19.8) to 28.8 (SD: 20.5), p <0.001, and in the NSAID group from 45.2 (SD: 22.6) to 34.9 (SD: 25.0), p = 0.018. Other signs of improvement were seen in function as measured by the Oswestry Disability Index (ODI), which improved at 1 month in the exercise group (p<0.001), while physical function also improved at 1 month in the exercise group (p= 0.038). Another improvement was observed in pain, function and quality of life which was maintained at 3 and 6 months in both groups. Finally, recurrence was higher in the NSAID group: 25.5 % vs. 7.1 % (p= 0.04) at 1 month; 25.5 % (p= 0.04) at 1 month; 25.5 % (p= 0.038) in the exercise group (p= 0.038) at 1 month.

Different operation sequences between acupuncture and cupping therapy for lumbar muscle strain with cold and dampness: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy on lumbar muscle strain with cold and dampness between the different operation sequences of acupuncture and cupping therapy.@*METHODS@#Seventy-six patients with lumbar muscle strain with cold and dampness were randomly divided into an acupuncture + cupping group (A + C group, 38 cases) and a cupping + acupuncture group (C + A group, 38 cases, 1 case dropped off). In the A + C group, cupping therapy was delivered 10 min after the end of treatment with acupuncture, while in the C + A group, acupuncture therapy was exerted 10 min after the end of treatment with cupping. Acupuncture was applied to Mingmen (GV 4), Yaoyangguan (GV 3), ashi point and bilateral Shenshu (BL 23), Dachangshu (BL 25), Weizhong (BL 40) and Yanglingquan (GB 34), and the needles were retained for 30 min in each intervention. Flash cupping was operated along the bilateral sides of the lumbar spine for 3 min, and the cups were retained for 10 min at bilateral Shenshu (BL 23), Dachangshu (BL 25) and ashi points. The intervention was delivered once every two days, 3 times weekly, for 3 weeks totally in each group. The scores of visual analogue scale (VAS) and Oswestry disability index (ODI), TCM syndrome score and the mean temperature of the lumbar region before and after treatment were compared between the two groups. The safety and the clinical efficacy were assessed for the interventions of the two groups.@*RESULTS@#Compared with the values before treatment, except for the sleep score of ODI, the VAS scores, ODI scores and TCM syndrome scores were decreased after treatment (P<0.01, P<0.05); while the mean temperature of the lumbar region was increased (P<0.01) in both groups. After treatment, the VAS score and the pain score of ODI in the C + A group were lower than those in the A + C group (P<0.05). The incidence rate of adverse reactions of the C + A group was lower than that of the A + C group (P<0.01). The effective rate in the A+C group was 92.1% (35/38), that in the C+A group was 94.6%(35/37), there was no statistical difference between the two groups (P>0.05).@*CONCLUSION@#Different operation sequences between acupuncture and cupping therapy obtain the similar efficacy on lumbar muscle strain with cold and dampness, but cupping therapy delivered prior to acupuncture has certain advantages in relieving pain and improving safety.

The posture decoding technique can improve the pelvis carriage and lumbar motion of patients with lower crossed syndrome, relieving back pain and relaxing the back muscles / 中华物理医学与康复杂志

Objective:To observe the clinical effectiveness of manual therapy based on posture decoding for patients with lower crossed syndrome (LCS).Methods:Thirty-six LCS patients were randomly divided into an observation group and a control group, each of 18. The observation group received manual therapy based on posture decoding, while the control group was treated with proprioceptive neuromuscular facilitation (PNF), both in 20min sessions, once a week for 4 weeks. Before the experiment, after one, two and four weeks of treatment and followed-up 4 and 8 weeks later, both groups were evaluated using a visual analogue scale (VAS), the Oswestry Disability Index (ODI) and finger-floor distance (FFD). Anterior pelvic tilt angles (ASIS-PSISs), sacral slopes (SS), lumbar curve index (LCI) and surface EMG flexion-relaxation ratios (FRRs) were also recorded from both groups before and after the treatment.Results:After one and four weeks of the treatment, the average VAS, ODI, and FFD had decreased significantly in both groups, with all significantly lower in the observation group, on average. At the final follow-up, the average VAS and ODI scores of both groups were significantly lower than before the treatment, with those of the observation group significantly lower than the control group′s averages. After 4 weeks of treatment significant differences were observed also in the group′s average ASIS-PSISs, SSs and LCIs compared with before the treatment. And right after the treatment the left and right surface electromyography FRRs of the observation group were significantly higher than those of the control group.Conclusion:Manual therapy based on posture decoding can significantly improve the pelvis forward angle and lumbar motion of LCS patients, relieving back pain and relaxing back muscles.

Management of Lumbar Disc Herniation with Radiculopathy Through Ayurveda - A Case Study

Lumbar disc herniation is a major health problem, affecting the most productive population globally. It has closest resemblance with Gridhrasi mentioned in Ayurvedic classics. Treatments available in conventional sciences have limitations such as relapse of acute episodes. Here an effort was made to treat a case of L5-S1 disc extrusion with radiculopathy using a comprehensive Ayurveda treatment protocol. The protocol includes a set of treatment procedures along with certain internal medicines. Changes were analysed with the help of VAS scale, SLRT and Oswestry disability index and showed significant improvements. This case is an evidence to demonstrate the effectiveness of Ayurveda treatments in case of LDH with radiculopathy.

Bone cement distribution of percutaneous curved vertebroplasty for the treatment of osteoporotic vertebral compression fractures / 中国组织工程研究

BACKGROUND: Percutaneous curved vertebroplasty is a new method for the treatment of osteoporotic vertebral compression fractures, which can achieve a good therapeutic effect, while the distribution of bone cement has not been explored thoroughly. OBJECTIVE: To retrospectively analyze the therapeutic effect of percutaneous curved vertebroplasty and the distribution characteristics of bone cement in the treatment of osteoporotic vertebral compression fractures. METHODS: A total of 28 patients with osteoporotic vertebral compression fractures of a single thoracic or lumbar vertebrate, who were admitted to Qingdao Municipal Hospital from June 2017 to February 2018, including 2 males and 26 females, aged 62-86 years old, underwent percutaneous curved vertebroplasty and were retrospectively reviewed. The bone cement was injected at the puncture side, the middle of the vertebrate and the contralateral side respectively. The change of anterior vertebral body height of the injured vertebrae and the leakage of bone cement postoperatively were observed according to X-ray images preoperatively, 48 hours and 6 months postoperatively. The bone cement distribution within the vertebrate was observed by CT scanning. Visual analogue scale score and Oswestry disability index were recorded for the evaluation of recovery. All protocols were approved by the Ethical Committee of Qingdao Municipal Hospital. RESULTS AND CONCLUSION: (1) There were 6 out of 28 cases of bone cement leakage, including 4 cases of paravertebral leakage and 2 cases of intervertebral space leakage, and no clinical symptoms were observed in all the 6 cases. CT scanning showed that the bone cement was mainly distributed in the anterior 2/3 of the vertebral body. The maximum distribution area of bone cement was (4.5±0.9) cm2, with the contralateral area (2.0±0.5) cm2 and the puncture side area (2.5±0.7) cm2, which makes the ratio of the puncture side area versus contralateral area 0.85±0.27. (2) The anterior vertebral body heights preoperatively showed no significant difference than those postoperatively in 28 patients (P > 0.05). (3) The visual analogue scale score and Oswestry disability index 48 hours and 6 months postoperatively were both significantly different from those before operation (P < 0.05). (4) The results showed that percutaneous curved vertebroplasty treatment of osteoporotic vertebral compression fractures has the advantages of accurate surgical effects and even distribution of bone cement.

Comparison of percutaneous vertebroplasty and percutaneous curved vertebroplasty for osteoporotic vertebral compression fractures: Distribution and leakage rate of injected bone cement / 中国组织工程研究

BACKGROUND: Percutaneous curved vertebroplasty is a modified surgical method of percutaneous vertebroplasty; the most prominent feature of which is that it can make the bone cement distributed symmetrically and balance the strength on both sides of the vertebral body. In theory, it can ensure the distribution of bone cement in the vertebral body, and solve the problem that the uneven distribution of bone cement in the traditional percutaneous vertebroplasty and single injection leads to poor pain relief effect in the fracture area. OBJECTIVE: To compare the clinical efficacy of percutaneous curved vertebroplasty and percutaneous vertebroplasty bone cement injection in the treatment of osteoporotic vertebral compression fractures, and to discuss the value of percutaneous curved vertebroplasty in clinical application. METHODS: Seventy patients with single vertebral osteoporotic vertebral compression fractures from the Third Affiliated Hospital of AnHui Medical University between 2017 and 2018 were selected. The patients were randomly divided into two groups. Percutaneous curved vertebroplasty group (n=35) received treatment with percutaneous curved vertebroplasty. Percutaneous vertebroplasty group (n=35) received treatment with percutaneous vertebroplasty. Distribution and leakage of bone cement were observed in the two groups. Visual analogue scale score and Oswestry disability index were assessed preoperatively and 1 day postoperatively. Postoperative follow-up was conducted for 1 year to observe the recovery of the height of the anterior edge of the injured vertebra and the occurrence of adjacent vertebral fractures. The trial was approved by the Ethics Committee of the Third Affiliated Hospital of Anhui Medical University. RESULTS AND CONCLUSION: (1) Compared with the percutaneous vertebroplasty group, the distribution of bone cement was more uniform and satisfactory (P0.05). (4) There was no significant difference in the incidence of adjacent vertebral fractures between the two groups (P>0.05). (5) The results showed that compared with the treatment of percutaneous vertebroplasty, the treatment of osteoporotic vertebral body compression fractures by percutaneous curved vertebroplasty can reduce the rate of bone cement leakage and improve the quality of life of patients.

Facet joint injection versus percutaneous kyphoplasty for mild vertebral fragility fractures: Rapid analgesia and restoration of spinal stability / 中国组织工程研究

BACKGROUND: Percutaneous kyphoplasty (PKP) for the treatment of osteoporotic compression fractures has been widely recognized in clinical practice, but clinicians are still impelled to seek for new treatment regimens due to complications such as bone cement leakage and adjacent vertebral re-fracture. OBJECTIVE: To compare the therapeutic efficacy of facet joint injection (FJI) and PKP in the treatment of mild vertebral fragility fractures. METHODS: Forty-six patients with mild vertebral fragility fractures (osteoporotic fractures) were divided into FJI group and PKP group according to the treatment regimens. The two groups of patients were treated with FJI and PKP separately based on standardized anti-osteoporosis treatment. The data of each group were recorded before and 1 week, 1, 3, 6, and 12 months after treatment. The analgesic efficacy was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI). Spine stability was evaluated by anterior vertebral height, kyphotic angle and lumbar spine density and the incidence of re-fracture were compared. The study protocol was implemented in line with the ethic requirements of Shanxi Bethune Hospital, Shanxi Academy of Medical Sciences in China. Informed consent was obtained from each patient. RESULTS AND CONCLUSION: Intragroup comparison: VAS and ODI scores of patients in both groups were significantly decreased in each period after treatment compared with the baseline (P 0.05). After treatment, the anterior vertebral body height and kyphosis angle in the PKP group were better than those in the FJI group (P 0.05). Standardized anti-osteoporosis treatment with either FJI or PKP can provide effective analgesia for patients with mild vertebral fragility fracture, and PKP has certain advantages in rapid analgesia and recovery of spinal stability.

Effect of different distribution types of bone cement after percutaneous kyphoplasty on osteoporotic vertebral compression fractures at different sites / 中国组织工程研究

BACKGROUND: Percutaneous kyphoplasty (PKP) has become an effective method for the treatment of osteoporotic vertebral compression fractures, but the distribution of bone cement in the vertebral body can cause certain differences in postoperative clinical symptoms. OBJECTIVE: To investigate the clinical effect of bone cement distribution on the treatment of vertebral compression fractures in different sites after percutaneous kyphoplasty. METHODS: A retrospective analysis of eligible 339 patients with vertebral compression fractures at different sites who received treatment at the Department of Orthopedics, Affiliated Zhongshan Hospital of Dalian University from January 2017 to January 2019 were included in this study. These patients were aged 60-85 years. They were divided into a thoracic fracture group (n=144) and a lumbar fracture group (n=195). All patients received bone cement injection after percutaneous kyphoplasty. After surgery, the diffusion distribution of bone cement in the vertebral body was divided into I-V types in each group. Visual Analogue Scale score and Oswestry Disability Index were evaluated before surgery, and 3 days and 6 months after surgery. This study was approved by the Medical Ethics Committee, Affiliated Zhongshan Hospital of Dalian University, China. RESULTS AND CONCLUSION: (1) At 3 days and 6 months after surgery, Visual Analogue Scale score and Oswestry Disability Index were significantly decreased compared with before surgery (P 0.05). (3) At 6 months after surgery, there was no significant difference in Oswestry Disability Index between different distribution types of bone cement in the thoracic fracture group (P > 0.05). At 6 months after surgery, Visual Analogue Scale score in patients with types I, II and III bone cement distribution was significantly lower than in those with types IV and V bone cement distribution (P 0.05). At 6 months after surgery, Visual Analogue Scale score in patients with types I, II and III bone cement distribution was significantly lower than in that in patients undergoing types IV and V bone cement distribution (P < 0.05). (5) These results suggest that after percutaneous kyphoplasty, bone cement distributed in types I-III can lead to better pain relief than that distributed in other types.

A Comparative Study between Pedicle Screw Instrumentation with Posterolateral Fusion and Pedicle Screw Instrumentation with Interbody Fusion in Patients of Lumbar Spondylolisthesis

Background: Many different treatment modalities have been advocated by different authors from time to time for lumbarspondylolisthesis. Many cases, the condition can be treated conservatively. However, when the symptoms persist, surgeryneeds to be performed. The principle of underlying surgery includes stabilization of the slipping vertebrae. Various operativemethods encompassing this principle include stabilization with pedicle screw fixation and fusion which can either posterolateralor interbody fusion, anterior lumbar interbody fusion, posterior lumbar interbody fusion, or transforaminal lumbar interbodyfusion. The objective of this study was to compare the surgical efficacy in terms of stability and fusion achieved using pediclescrew-rod instrumentation with posterolateral fusion and pedicle screw-rod instrumentation with interbody fusion in lumbarspondylolisthesis and to study THE functional and clinical recovery using the Revised Oswestry Disability Index score.Materials and Methods: A prospective study was carried out to compare the clinical and radiological outcomes between Pediclescrew-rod instrumentation with either posterolateral fusion and interbody fusion after adequate decompression in patient oflumbar spondylolisthesis. All patients as per the inclusion criteria were admitted, underwent surgery between March 2010 andMarch 2012, and were included in the study.Results: The total of 50 patients was included in our study. Both male and female patients were equally distributed in both thegroups, wherein postreolateral fusion had 13 female patients and those with interbody fusion had 13 male patients. Our studyshows marked improvement in Revised Oswestry Disability score postoperatively with good-to-excellent results in both thegroups. We achieved good solid radiological fusion earliest on the 3rd month in both the groups with good stability.Conclusion: Our results showed similar clinical and functional outcome in both the groups with no significant statistical differencefound. However, we conclude that in cases where reduction is required and there is instability affecting the three column ofspine interbody fusions with pedicle screws-rod instrumentation provide a more solid mechanical construct.

Ayurvedic Management Of Lumbar Spondylolisthesis (kati Shoola) With Special Reference To Chincha Lavana Sweda- A Case Report

Spondylolisthesis is described as a translation of a vertebra with respect to the vertebra below without any modification or notable lesion to the pars interarticularis. Lumbar spondylolisthesis can be considered as various conditions like Kati shoola, Kati Graha, Trika Graha, Prushta Graha, Trika Shoola, Prushta Shoola, Grudrasi in Ayurveda. The present article deals with a case of diagnosed Grade 1 lumbar spondylolisthesis of L4 over L5 and got advised for surgery. The Ayurvedic diagnosis of Kati soola was made. Management included Abhyanga, Kativasti, Kshira vasti, Virechana, Vaitarana vasti and Chincha lavana sweda along with internal medications. Chincha lavana sweda is a very simple and effective Swedana procedure to cure pain in low back, especially due to Spondylolisthesis. But it is not widely used. This case report also wants to introduce the technique to Ayurvedic practitioners who are unaware of it. Before treatment, total score on Oswestry low back pain disability questionnaire was 34 (68%) and at the time of discharge, the score was 8 (16%). On Roland-Morris low back pain and disability questionnaire, the before treatment score was 17 and at the time of discharge it was reduced to 4. That means the patient showed an improvement of 76% on Roland-Morris low back pain and disability questionnaire. The present case report substantiates effectiveness of classical Ayurvedic Management in spondylolosthesis.

Perioperative Factors Associated with Severe Pain in Post-Anesthesia Care Unit after Thoracolumbar Spine Surgery: A Retrospective Case-Control Study

STUDY DESIGN: A retrospective case-control study. PURPOSE: To evaluate the effect of nitrous oxide and anesthetic and operative factors associated with severe pain in the early postoperative period after thoracolumbar spine surgery. OVERVIEW OF LITERATURE: Thoracolumbar spine surgery is the most common procedure in spine surgery, and up to 50% of the patients suffer from moderate to severe pain. Nitrous oxide has analgesic, anxiolytic, and anesthetic effects; nevertheless, its benefits for early postoperative pain control and opioid consumption remain to be established. METHODS: The medical records of eligible participants who underwent thoracolumbar spine surgery between July 2016 and February 2017 were reviewed. Enrolment was performed consecutively until reaching 90 patients for the case (severe pain) group (patients with a pain score of >7 out of 10 at least once during the post-anesthesia care unit [PACU] admission), and 90 patients for the control (mild-to-moderate pain) group (patients with a pain score of <7 in every PACU assessment). The data collected comprised patient factors, anesthetic factors, surgical factors, PACU pain score, and PACU pain management. RESULTS: A total of 197 patients underwent thoracolumbar spine surgery with an incidence of early postoperative severe pain of 53.3%. The case-control study revealed no differences in the factors related to pain intensity. A subgroup analysis was performed for failed back surgery syndrome (FBSS), spinal stenosis, and spondylolisthesis. After multivariate analyses, only the age group of 19–65 years and the baseline Oswestry Disability Index (ODI) were found to be significant risk factors for early postoperative severe pain in the PACU (odds ratio [OR], 2.86; 95% confidence interval [CI], 1.32–6.25; OR, 1.03; 95% CI, 1.01–1.05, respectively). CONCLUSIONS: Nitrous oxide, anesthetic agents, and surgical techniques did not affect the early postoperative pain severity. Age under 66 years and the baseline ODI were the significant risk factors for pain intensity during the early postoperative period of the FBSS, spinal stenosis, and spondylolisthesis subgroups.

Development of a Modified Disability Questionnaire for Evaluating Disability Caused by Backache in India and Other Developing Countries

STUDY DESIGN: Prospective observational study. PURPOSE: To evaluate the disability domains relevant to Indian patients with low backache and propose a modified disability questionnaire for such patients. OVERVIEW OF LITERATURE: The Oswestry Disability Index (ODI) is a self-reported measurement tool that measures both pain and functional status and is used for evaluating disability caused by lower backache. Although ODI remains a good tool for disability assessment, from the Indian perspective questions related to weight lifting and sexual activity of ODI are questioned in some of the earlier studies. Activities of daily living in Indian patients vary substantially from those in other populations and include activities like bending forwards, sitting in floor and squatting which are not represented in the ODI. METHODS: In this prospective observational study, a seven-step approach was used for the development of a questionnaire. Thirty patients were interviewed to identify the most challenging issue they faced while performing their daily activities (by free listing) and understand how important the questionnaire items were in terms of the standard ODI. Thus, a comprehensive disability questionnaire comprising 14 questions was developed and administered to 88 patients. Both qualitative (interviews) and quantitative methods (to establish the validity, reliability, and correlation with the Visual Analog Scale [VAS] and Rolland Morris disability questionnaire) were used to identify the 10 questions that best addressed the disability domains relevant to Indian patients. RESULTS: According to free listing, four new questions pertaining to bending forward, sitting on the floor, walking on uneven surfaces, and work-related disabilities were included. In the second phase, wherein the questionnaire with 14 items was used, 56.8% patients did not answer the questions related to sexual activity, whereas 23.8% did not answer those related to walking on uneven surfaces. The modified questionnaire demonstrated good internal consistency (Cronbach's alpha=0.892) and correlation with the Rolland Morris questionnaire (Cronbach's alpha=0.850, p>0.05), as well as with the VAS score for disability (Cronbach's alpha=0.712, p>0.05) and pain (Cronbach's alpha=0.625, p>0.05). CONCLUSIONS: A modified disability questionnaire that was designed by adding two questions related to bending forward and work status and removing questions related to sexual activity and weight lifting or traveling (depending on the occupation) can help evaluate disability caused by back pain in Indian population.

Prevalence of Frailty in Patients with Osteoporotic Vertebral Compression Fracture and Its Association with Numbers of Fractures

PURPOSE: To assess the association between frailty and osteoporotic vertebral compression fracture (OVCF) and to evaluate the relationship between numbers of OVCFs and frailty. MATERIALS AND METHODS: We enrolled 760 subjects, including 59 patients (with OVCF) and 701 controls (without OVCF). Successful matching provided 56 patient-control pairs. We analyzed principal clinical and demographic information, which included sex, age, height, weight, body mass index (BMI), variable frailty phenotypes, and Oswestry Disability Index (ODI) and EuroQol 5-dimension questionnaire (EQ-5D) scores. The association between frailty and OVCF was ascertained. In addition, the degrees of disability and quality of life attributable to frailty were determined. RESULTS: The prevalence of frailty was significantly higher in the OVCF group than in the control group (p < 0.001). Most of the frailty phenotypes, such as exhaustion, physical inactivity, slowness, and handgrip strength, were also significantly observed in the OVCF group. Within the OVCF group, the participants with frailty had significantly higher disability and lower quality of life than those in a robust state (p < 0.001 for ODI and EQ-5D). In addition, the multivariate logistic regression analysis demonstrated that the patients with low BMI [odds ratio (OR)=0.704; 95% confidence interval (CI), 0.543–0.913] and ≥3 fractures (OR=9.213; 95% CI, 1.529–55.501) within the OVCF group were associated with higher odds of frailty. CONCLUSION: The present study showed significant relationships between frailty and OVCF, severity of symptoms, and disability induced by OVCF. Furthermore, frailty could be a causal and/or resulting factor of OVCFs.

Clinical Observations on Short Thrust Needling Treatment for Osteoporotic Vertebral Compression Fractures / 上海针灸杂志

Objective To investigate the therapeutic effect of short thrust needling on osteoporotic vertebral compression fractures.Method Seventy-two patients with osteoporotic vertebral compression fractures were randomly allocated to observation and controlgroups, 36 cases each.In the observation group,short thrust needlingwas used with lifting-thrusting and twirling manipulation; the bone was rubbed with the needle tip up anddownin the place near the bone; reinforcing manipulation was performed for nine times after arrival of qi.The control group received conventional acupuncture with uniform reinforcing-reducing manipulation.Both groups were treated four weeks as a course for two courses.The Visual Analogue Scale(VAS) score and the Oswestry Disability Index (ODI)score were recorded in the two groups before and after four and eight weeks of treatment.The clinical therapeutic effects were evaluated.Result The total efficacy rate was 94.4% in the observation group.Which was higher than 66.7% in the control group (P<0.05).Boththe VAS and ODI scores were lower after treatment compared with before (P<0.05) and decreased significantly more in the observation than in the control group(P<0.05).Conclusion Short thrust needling canmarkedly relieve the pain and dysfunction in patients with osteoporotic vertebral compression fractures.Its the rapeutic effect is significantly better than that of conventional acupuncture.

Clinical Observations on Acupuncture plus Lumbar Vertebra-stabilizing Muscle Group Training for Treatment of Lumbar Intervertebral Disc Herniation / 上海针灸杂志

Objective To investigate the clinical improving effect on the symptoms of acupuncture at point Weizhong(BL40) plus following lumbar vertebra-stabilizing core muscle group training in patients with lumbar intervertebral disc herniation. Method Sixty patients with lumbar intervertebral disc herniation were randomized to a treatment group (30 cases) and a control group (30 cases). The treatment group received acupuncture at point Weizhong plus following lumbar vertebra-stabilizing core muscle group training and the control group, oral administration of celecoxib capsules. After treatment, the clinical improving effect on the symptoms was evaluated in the patients using the NRS, JOA Lumbar Scoring and ODI. Result The total efficacy rate was 100% in the treatment group and 53.3%in the control group. Post-treatment NRS, JOA and ODI scores were better in the treatment group than in the control group; there were statistically significant differences (P<0.001). Conclusion Acupuncture at point Weizhong plus following lumbar vertebra-stabilizing core muscle group training can effectively treat lumbar intervertebral disc herniation.
