Review
Degeneration of the intervertebral disc (IVD) is a normal part of aging. Due to the spine's declining function and the development of pain, it may affect one's physical health, mental health, and socioeconomic status. Most of the intervertebral disc degeneration (IVDD) therapies today focus on the symptoms of low back pain rather than the underlying etiology or mechanical function of the disc. The deteriorated disc is typically not restored by conservative or surgical therapies that largely focus on correcting symptoms and structural abnormalities. To enhance the clinical outcome and the quality of life of a patient, several therapeutic modalities have been created. In this review, we discuss genetic and environmental causes of IVDD and describe promising modern endogenous and exogenous therapeutic approaches including their applicability and relevance to the degeneration process.

Review
A Systematic Review of Clinical Practice Guidelines for Persons With Non-specific Low Back Pain With and Without Radiculopathy: Identification of Best Evidence for Rehabilitation to Develop the WHO's Package of Interventions for Rehabilitation.
OBJECTIVE
To Identify evidence-based rehabilitation interventions for persons with non-specific low back pain (LBP) with and without radiculopathy and to develop recommendations from high-quality clinical practice guidelines (CPGs) to inform the World Health Organization's (WHO) Package of Interventions for Rehabilitation (PIR).
DATA SOURCE
We searched MEDLINE, EMBASE, CINAHL, PsycINFO, National Health Services Economic Evaluation Database, Health Technology Assessment Database, PEDro, the Trip Database, the Index to Chiropractic Literature and the gray literature.
STUDY SELECTION
Eligible guidelines were (1) published between 2009 and 2019 in English, French, Italian, or Swedish; (2) included adults or children with non-specific LBP with or without radiculopathy; and (3) assessed the benefits of rehabilitation interventions on functioning. Pairs of independent reviewers assessed the quality of the CPGs using AGREE II.
DATA SYNTHESIS
We identified 4 high-quality CPGs. Recommended interventions included (1) education about recovery expectations, self-management strategies, and maintenance of usual activities; (2) multimodal approaches incorporating education, exercise, and spinal manipulation; (3) nonsteroidal anti-inflammatory drugs combined with education in the acute stage; and (4) intensive interdisciplinary rehabilitation that includes exercise and cognitive/behavioral interventions for persistent pain. We did not identify high-quality CPGs for people younger than 16 years of age.
CONCLUSION
We developed evidence-based recommendations from high-quality CPGs to inform the WHO PIR for people with LBP with and without radiculopathy. These recommendations emphasize the potential benefits of education, exercise, manual therapy, and cognitive/behavioral interventions.

Meta-Analysis Review
PURPOSE
Chronic low back pain (CLBP) is an aging and public health issue that is a leading cause of disability worldwide and has a significant economic impact on a global scale. Treatments for CLBP are varied, and there is currently no study with high-quality evidence to show which treatment works best. Exercise therapy has the characteristics of minor harm, low cost, and convenient implementation. It has become a mainstream treatment method in clinics for chronic low back pain. However, there is insufficient evidence on which specific exercise regimen is more effective for chronic non-specific low back pain. This network meta-analysis aimed to evaluate the effects of different exercise therapies on chronic low back pain and provide a reference for exercise regimens in CLBP patients.
METHODS
We searched PubMed, EMBASE, Cochrane Library, and Web of Science from inception to 10 May 2022. Inclusion and exclusion criteria were used for selection. We collected information from studies to compare the effects of 20 exercise interventions on patients with chronic low back pain.
RESULTS
This study included 75 randomized controlled trials (RCTs) with 5,254 participants. Network meta-analysis results showed that tai chi [standardized mean difference (SMD), -2.11; 95% CI, -3.62 to -0.61], yoga (SMD, -1.76; 95% CI -2.72 to -0.81), Pilates exercise (SMD, -1.52; 95% CI, -2.68, to -0.36), and sling exercise (SMD, -1.19; 95% CI, -2.07 to -0.30) showed a better pain improvement than conventional rehabilitation. Tai chi (SMD, -2.42; 95% CI, -3.81 to -1.03) and yoga (SMD, -2.07; 95% CI, -2.80 to -1.34) showed a better pain improvement than no intervention provided. Yoga (SMD, -1.72; 95% CI, -2.91 to -0.53) and core or stabilization exercises (SMD, -1.04; 95% CI, -1.80 to -0.28) showed a better physical function improvement than conventional rehabilitation. Yoga (SMD, -1.81; 95% CI, -2.78 to -0.83) and core or stabilization exercises (SMD, -1.13; 95% CI, -1.66 to -0.59) showed a better physical function improvement than no intervention provided.
CONCLUSION
Compared with conventional rehabilitation and no intervention provided, tai chi, toga, Pilates exercise, sling exercise, motor control exercise, and core or stabilization exercises significantly improved CLBP in patients. Compared with conventional rehabilitation and no intervention provided, yoga and core or stabilization exercises were statistically significant in improving physical function in patients with CLBP. Due to the limitations of the quality and quantity of the included studies, it is difficult to make a definitive recommendation before more large-scale and high-quality RCTs are conducted.

Randomized Controlled Trial
Effectiveness of an exercise intervention based on preactivation of the abdominal transverse muscle in patients with chronic nonspecific low back pain in primary care: a randomized control trial.
BACKGROUND
Low back pain is one of the most common disabling pathologies in humanity worldwide. Physical exercises have been used in recent decades to reduce the pain, improve the functionality of the lumbar spine and avoid relapses. The purpose of the study is to analyze the effect of a program based on re-education exercises involving preactivation of the abdominal transverse muscle compared to conventional treatment in adults with chronic nonspecific low back pain.
METHODS
A two-arm, single-blind randomized control trial with 35 primary care patients with chronic nonspecific low back pain. Both groups received a 4-week intervention. Data were collected at baseline and at the end of the intervention. Sixteen patients participated in the intervention group, and 19 patients in the control group.
RESULTS
For the experimental group, the outcomes of disability and activation of the abdominal transverse muscle decreased significantly (MD -2.9; CI 95% -5.6 to -0.35; η2 = 0.14; p = 0.028) and (MD 2.3; CI 95% 0.91 to 3.67; η2 = 0.25; p = 0.002) respectively, with a large effect size, compared to the control group. There were no differences between the groups in pain intensity, thickness, and resistance of the transverse abdominal muscle.
CONCLUSION
A 4-week specific program based on re-education exercises of the preactivation of the abdominal transverse muscle is more effective than conventional treatment for reducing disability and increasing the activation of the abdominal transverse muscle measured by VAS scale and PBU.

Journal of Physiotherapy Jul 2023How much are the reductions in pain intensity and improvements in physical function from Pilates exercise mediated by changes in pain catastrophising and kinesiophobia? (Randomized Controlled Trial)
Randomized Controlled Trial
Pain catastrophising and kinesiophobia mediate pain and physical function improvements with Pilates exercise in chronic low back pain: a mediation analysis of a randomised controlled trial.
QUESTION
How much are the reductions in pain intensity and improvements in physical function from Pilates exercise mediated by changes in pain catastrophising and kinesiophobia?
DESIGN
This was a secondary causal mediation analysis of a four-arm randomised controlled trial testing Pilates exercise dosage (once, twice or thrice per week) against a booklet control.
PARTICIPANTS
Two hundred and fifty-five people with chronic low back pain.
DATA ANALYSIS
All analyses were conducted in R software (version 4.1.2) following a preregistered analysis plan. A directed acyclic graph was constructed to identify potential pre-treatment mediator-outcome confounders. For each mediator model, we estimated the intervention-mediator effect, the mediator-outcome effect, the total natural indirect effect (TNIE), the pure natural direct effect (PNDE), and the total effect (TE).
RESULTS
Pain catastrophising mediated the effect of Pilates exercise compared with control on the outcomes pain intensity (TNIE MD -0.21, 95% CI -0.47 to -0.03) and physical function (TNIE MD -0.64, 95% CI -1.20 to -0.18). Kinesiophobia mediated the effect of Pilates exercise compared with control on the outcomes pain intensity (TNIE MD -0.31, 95% CI -0.68 to -0.02) and physical function (TNIE MD -1.06, 95% CI -1.70 to -0.49). The proportion mediated by each mediator was moderate (21 to 55%).
CONCLUSION
Reductions in pain catastrophising and kinesiophobia partially mediated the pathway to improved pain intensity and physical function when using Pilates exercise for chronic low back pain. These psychological components may be important treatment targets for clinicians and researchers to consider when prescribing exercise for chronic low back pain.

Short-Term Effects of Manual Therapy plus Capacitive and Resistive Electric Transfer Therapy in Individuals with Chronic Non-Specific Low Back Pain: A Randomized Clinical Trial Study.
Chronic non-specific low back pain (CNSLBP) is defined as back pain that lasts longer than 12 weeks. Capacitive and resistive electric transfer (TECAR) therapy utilizes radiant energy to generate endogenous heat and is widely used for the treatment of chronic musculoskeletal pain. The aim of this study was to investigate the efficacy of manual therapy (MT) program combined with TECAR therapy in individuals with CNSLBP. Sixty adults with CNSLBP were randomly divided equally into three groups. The first group followed an MT protocol in the lumbar region (MT group), the second group followed the same MT protocol combined with TECAR therapy (MT + TECAR group) using a conventional capacitive electrode as well as a special resistive electrode bracelet, and the third group (control group) received no treatment. Both intervention programs included six treatments over two weeks. Pain in the last 24 h with the Numeric Pain Rating Scale (NPRS), functional ability with the Roland-Morris Disability Questionnaire (RMDQ), pressure pain threshold (PPT) in the lumbar region with pressure algometry, and mobility of the lumbo-pelvic region through fingertip-to-floor distance (FFD) test were evaluated before and after the intervention period with a one-month follow-up. Analysis of variance with repeated measures was applied. In the NPRS score, both intervention groups showed statistically significant differences compared to the control group both during the second week and the one-month follow-up ( < 0.001). Between-group differences were also noticed between the two intervention groups in the second week ( < 0.05). Differences in the RMDQ score were detected between the intervention groups and the control group in the second week and at the one-month follow-up ( < 0.001), while differences between the two intervention groups were only detected at the one-month follow-up ( < 0.001). Regarding the PPT values, differences were found mainly between the MT + TECAR group and the control group and between the MT + TECAR group and the MT group ( < 0.05), with the MT + TECAR group in most cases showing the greatest improvement compared to the other two groups, which remained statistically significant at the one-month follow-up ( < 0.05). Finally, both intervention groups improved the mobility of the lumbo-pelvic region at both time points compared to the control group without, however, statistically significant differences between them ( > 0.05). The application of an MT protocol with TECAR therapy appeared more effective than conventional MT as well as compared to the control group in reducing pain and disability and improving PPT in individuals with CNSLBP. No further improvement was noted in the mobility of the lumbo-pelvic region by adding TECAR to the MT intervention.

Effect of an Artificial Intelligence-Based Self-Management App on Musculoskeletal Health in Patients With Neck and/or Low Back Pain Referred to Specialist Care: A Randomized Clinical Trial.
IMPORTANCE
Self-management is a key element in the care of persistent neck and low back pain. Individually tailored self-management support delivered via a smartphone app in a specialist care setting has not been tested.
OBJECTIVE
To determine the effect of individually tailored self-management support delivered via an artificial intelligence-based app (SELFBACK) adjunct to usual care vs usual care alone or nontailored web-based self-management support (e-Help) on musculoskeletal health.
DESIGN, SETTING, AND PARTICIPANTS
This randomized clinical trial recruited adults 18 years or older with neck and/or low back pain who had been referred to and accepted on a waiting list for specialist care at a multidisciplinary hospital outpatient clinic for back, neck, and shoulder rehabilitation. Participants were enrolled from July 9, 2020, to April 29, 2021. Of 377 patients assessed for eligibility, 76 did not complete the baseline questionnaire, and 7 did not meet the eligibility criteria (ie, did not own a smartphone, were unable to take part in exercise, or had language barriers); the remaining 294 patients were included in the study and randomized to 3 parallel groups, with follow-up of 6 months.
INTERVENTIONS
Participants were randomly assigned to receive app-based individually tailored self-management support in addition to usual care (app group), web-based nontailored self-management support in addition to usual care (e-Help group), or usual care alone (usual care group).
MAIN OUTCOMES AND MEASURES
The primary outcome was change in musculoskeletal health measured by the Musculoskeletal Health Questionnaire (MSK-HQ) at 3 months. Secondary outcomes included change in musculoskeletal health measured by the MSK-HQ at 6 weeks and 6 months and pain-related disability, pain intensity, pain-related cognition, and health-related quality of life at 6 weeks, 3 months, and 6 months.
RESULTS
Among 294 participants (mean [SD] age, 50.6 [14.9] years; 173 women [58.8%]), 99 were randomized to the app group, 98 to the e-Help group, and 97 to the usual care group. At 3 months, 243 participants (82.7%) had complete data on the primary outcome. In the intention-to-treat analysis at 3 months, the adjusted mean difference in MSK-HQ score between the app and usual care groups was 0.62 points (95% CI, -1.66 to 2.90 points; P = .60). The adjusted mean difference between the app and e-Help groups was 1.08 points (95% CI, -1.24 to 3.41 points; P = .36).
CONCLUSIONS AND RELEVANCE
In this randomized clinical trial, individually tailored self-management support delivered via an artificial intelligence-based app adjunct to usual care was not significantly more effective in improving musculoskeletal health than usual care alone or web-based nontailored self-management support in patients with neck and/or low back pain referred to specialist care. Further research is needed to investigate the utility of implementing digitally supported self-management interventions in the specialist care setting and to identify instruments that capture changes in self-management behavior.

Meta-Analysis
IMPORTANCE
When sham acupuncture is set as a control in evaluating acupuncture, the sham needling technique is usually different from acupuncture. However, the sham procedure is conducted either at the same points that are used for the acupuncture group or at nonindicated points.
OBJECTIVE
To assess whether the outcome of sham acupuncture varies according to the needling points in sham-controlled trials of acupuncture for chronic nonspecific low back pain (CLBP) as an example.
DATA SOURCES
Searches of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the Allied and Complementary Medicine Database were conducted on February 12, 2023.
STUDY SELECTION
Randomized clinical trials (RCTs) assessing the outcomes of acupuncture in sham acupuncture-controlled or waiting list-controlled trials on CLBP were included.
DATA EXTRACTION AND SYNTHESIS
Two researchers independently extracted data on study characteristics and outcomes and assessed quality. Sham acupuncture was classified according to whether it was conducted at the same acupuncture points used in the acupuncture group, referred to as sham acupuncture therapy (verum) (SATV) or at different points, referred to as sham acupuncture therapy (sham) (SATS). Clinical similarity, transitivity, and consistency tests were conducted, followed by a random-effects frequentist network meta-analysis (NMA).
MAIN OUTCOMES AND MEASURES
The primary outcome was pain, and the secondary outcome was back-specific function. The first assessment after the end of treatment was chosen for analysis. Effect sizes are reported as standardized mean differences (SMD) with 95% CIs. The risk of bias was assessed using the Cochrane risk of bias tool, and the certainty of evidence for findings was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach.
RESULTS
Ten RCTs involving 4379 participants were included. In comparison with SATS, acupuncture was significantly associated with improvements in both pain (SMD, -0.33; 95% CI, -0.52 to -0.15) and function outcomes (SMD, -0.13; 95% CI, -0.25 to -0.02); however, there were no differences between acupuncture and SATV. In comparison with SATS, SATV was significantly associated with better pain (SMD, -0.45; 95% CI, -0.88 to -0.03) and function outcomes (SMD, -0.30; 95% CI, -0.56 to -0.05). The risk of bias that could affect the interpretation of the results was usually low, and the certainty of evidence was moderate to low.
CONCLUSIONS AND RELEVANCE
In this NMA, sham acupuncture needling at the same points as those in acupuncture was not a true placebo control for assessing the efficacy of acupuncture for CLBP and might underestimate the outcome of acupuncture in clinical settings.

BACKGROUND
Observational studies have suggested an association between inflammatory markers and low back pain (LBP), but the causal relationship between these factors remains uncertain.
METHODS
We conducted a bidirectional two-sample Mendelian randomization analysis (MR) study to investigate whether there is a causal relationship between inflammatory markers and low back pain. We obtained genetic data for CRP, along with its upstream inflammatory markers IL-6, IL-8, and IL-10, as well as low back pain from publicly available genome-wide association studies (GWAS). We applied several MR methods, including inverse variance weighting, weighted median, MR-Egger, Wald Ratio, and MR-PRESSO, to test for causal relationships. Sensitivity analyses were also conducted to assess the robustness of the results.
RESULTS
Our analyses utilizing the Inverse Variance Weighted (IVW) method, the MR-Egger method, and the weighted median method indicated that IL-6 may be associated with an increased risk of LBP (Effect Size: -0.009, 95% Confidence Interval: -0.013-0.006, p = 9.16e-08); however, in the reverse direction, there was no significant causal effect of LBP on inflammatory markers.
CONCLUSION
Our study used a Mendelian randomization approach and found that elevated IL-6 levels may reduce the risk of LBP.
