Rehabilitation for Low Back Pain: A Narrative Review for Managing Pain and Improving Function in Acute and Chronic Conditions

Promoting running as the best treatment for lower back pain in physiotherapy practice: a best practice implementation project

OBJECTIVES

This project aimed to promote running as the best treatment for lower back pain (LBP) in an outpatient setting.

INTRODUCTION

LBP is one of the most prevalent conditions worldwide. Sixty-two percent of all Germans experience episodes of non-specific back pain at least once a year, with one-fifth developing chronic conditions. Intervertebral disc (IVD) degeneration is a natural process, contributing to periods of acute LBP. However, the scientific literature and guidelines partially overlook the significance of water management in IVD. This implementation project sought to address this gap by educating patients about this process. Running and/or walking were chosen as general approaches for treatment rather than specific disease-related approaches.

METHODS

This implementation project was conducted in an outpatient physiotherapy clinic in Brandenburg, Germany, utilizing the JBI Evidence Implementation Framework. An evidence-informed clinical audit and feedback strategy was used to measure compliance with ten audit criteria. Five physiotherapists and 20 patients took part in the audits.

RESULTS

At baseline, only 20% of participating physiotherapists screened for yellow flags regarding psychological issues. However, after project implementation, this criterion scored 100% compliance. Some patients performed exercises independently, but confusion persisted regarding the choice of beneficial exercises. Patients continued running, but those who took a break due to pain expressed uncertainty about resuming.

CONCLUSIONS

The project highlighted the effectiveness of collaborative efforts between patients and therapists to address the issue. The project team's conviction in action and solution strategies serves as the foundation for this collaboration. This implementation strategy provided "running" patients with the confidence to either resume or reintegrate running after an extended break.

Effects of Paraspinal Intramuscular Injection of Atelocollagen in Patients with Chronic Low Back Pain: A Retrospective Observational Study

Background/Objectives: Atelocollagen is used for soft tissue repair and reconstruction by replacing defective or damaged muscles, membranes, ligaments, and tendons. This study aimed to evaluate the clinical efficacy and safety of additional paraspinal intramuscular injection of atelocollagen on lumbar epidural steroid injection for reducing pain and improving functional capacity of patients with chronic low back pain (CLBP). Methods: We retrospectively enrolled 608 consecutive patients with CLBP who received lumbar epidural steroid injection with or without additional paraspinal intramuscular injection of atelocollagen. The Numerical Rating Scale and the Oswestry Disability Index were used to assess pain and functional capacity, respectively, before the procedure, and three months after the injection. Also, we analyzed the relationship between the additional paraspinal intramuscular injection of atelocollagen and the success rate. Results: Both Numerical Rating Scale and the Oswestry Disability Index scores were significantly reduced in both groups at three months after injection. However, there was a significant difference between the two groups. Furthermore, the success rate was significantly higher in the additional paraspinal intramuscular injection of atelocollagen group. Conclusions: This study's results showed that additional paraspinal intramuscular injection of atelocollagen on lumbar epidural steroid injection reduced pain and improved functional capacity for patients with CLBP. Therefore, the paraspinal intramuscular injection of atelocollagen may be a promising option for the treatment of patients with CLBP.

Quality of Life, Disability Level, and Pain Intensity among Patients after Lumbar Disc Surgery: An Observational Three-Month Follow-Up Study

The prevalence of intervertebral disc degeneration in the lumbar region resulting in low back pain is high. One of the treatment options is neurosurgery. Previous studies and systematic reviews demonstrate the need to identify factors that affect the health-related quality of life of patients undergoing surgery. This study aimed to analyze the sociodemographic and clinical factors that affect the quality of life of patients undergoing lumbar disc surgery. A group of 128 patients was assessed for eligibility and qualified by radiological examinations for lumbar disc surgery by a neurosurgeon in the outpatient clinic. Finally, 110 patients were studied and evaluated 24 h and 3 months after surgery. Health-related quality of life (36-Item Short Form Survey, SF-36), disability level (Oswestry Disability Index, ODI), and pain intensity (Visual Analogue Scale, VAS) were assessed. The mean pain intensity before surgery was 7.8 ± 2.3 pts and decreased significantly 24 h after surgery, with a mean score of 3.8 ± 2.4 pts (p = 0.0000). After three months, the increase in pain intensity was at 4.8 ± 2.4 pts, but the score was still significantly better than before surgery (p = 0.0024). The mean ODI score before surgery was 29.3 ± 8.4 pts (slight disability), and three months after surgery, there was an insignificant increase to a mean value of 31.5 ± 10.4 pts (p = 0.0834). There was a statistically significant increase in quality-of-life scores at three months after surgery in the following domains: physical functioning (8.7%; p = 0.0176), bodily pain (26.2%; p = 0.0000), vitality (5.8%; p = 0.0132) and mental health (6.2%; p = 0.0163), and a decrease in role limitations due to physical problems (3.8; p = 0.0013) and general health perception (6.7%; p = 0.0112). In conclusion, the surgical procedure plays an important role in improving the quality of life of patients operated on for intervertebral disc degeneration. It was effective in reducing the pain level, especially 24 h after surgery; however, surgery did not affect the disability level.

A meaningful everyday life experienced by adults with acquired neurological impairments: A scoping review

OBJECTIVE

This scoping review explores the characteristics of a meaningful life appraised by adults living with an acquired neurological impairment.

INTRODUCTION

Limitations in function, activity or participation following a neurological injury or disease imposes comprehensive changes on the every-day life of the affected person and close relatives. Including patients' perception of a meaningful life is pivotal to facilitate motivation and individualize rehabilitation efforts to address the patients' wishes, hopes, needs, and preferences. Surprisingly, only little research has been devoted to illuminating what a meaningful life is from the impaired person's perspective. Hence, a scoping review of existing knowledge is needed to facilitate person-centered high-quality rehabilitation and research initiatives.

INCLUSION CRITERIA

All studies, published in English or Scandinavian languages describing a meaningful life as experienced by adult persons with neurological impairment were included. No search date range filter was selected.

METHODS

This review followed the Joanna Briggs Institute (JBI) methodology for scoping reviews according to a published protocol. A three-step search strategy was conducted in the databases PubMed, Cinahl, PsycINFO and Embase. At least two independent researchers conducted inclusions and exclusions, data extraction, and analyses. Covidence software was used to manage the information.

FINDINGS

We identified 307 studies. Of these, 20 were included and quality assessed. Findings are reported in accordance with the PRISMA- SCR checklist and descriptively presented mapped in three main domains and 10 ten sub-domains.

CONCLUSION

Current literature conveys no clear definition or perception of what a meaningful life is. However, across the 20 included studies, the following main characteristics were stepped forward as particularly significant for adults living with an acquired neurological impairment in regard to achieving a meaningful life: i) to be part of meaningful relationships and meaningful activities; ii) to become confident with one's perceived identity.

Neuromodulation of the Autonomic Nervous System in Chronic Low Back Pain: A Randomized, Controlled, Crossover Clinical Trial

Chronic pain is a societal concern influencing the autonomic nervous system. This system can be captured with automated pupillometry. The direct connection between the epidermal cells and the brain is presented as part of the central nervous system, reflecting the modulation of the autonomic system. This study's aim was to investigate if tape containing magnetic particles (TCMP) has an immediate effect on the autonomic nervous system (ANS) and influences chronic low back pain. Twenty-three subjects completed this study. Subjects were randomized to either receive the control tape (CT) or TCMP first. Each subject underwent a pain provocative pressure test on the spinous process, followed by the skin pinch test and automated pupillometry. Next, the TCMP/control tape was applied. After tape removal, a second provocative spinous process pressure test and skin pinch test were performed. Subjects returned for a second testing day to receive the other tape application. The results demonstrate that TCMP had an immediate significant effect on the autonomic nervous system and resulted in decreased chronic lower back pain. We postulate that this modulation by TCMP s has an immediate effect on the autonomic system and reducing perceived pain, opening a large field of future research.

Comparison of Analgesic Efficacy between Epidural and Perineural Administration of Autologous Conditioned Serum in the Conservative Treatment of Low Back Pain Due to Lumbar Degenerative Disc Disease: A Randomized, Open-Label, Controlled Clinical Trial

Lumbar degenerative disc disease (LDDD) is widely acknowledged as a significant contributor to low back pain (LBP), which is a prevalent and debilitating health condition affecting millions of individuals worldwide. The pathogenesis of LDDD and associated pain mechanisms are thought to be mediated by inflammatory mediators. Autologous conditioned serum (ACS, Orthokine) may be used for symptomatic treatment of LBP due to LDDD. This study aimed to compare the analgesic efficacy and safety of two routes of ACS administration, perineural (periarticular) and epidural (interlaminar), in the conservative treatment of LBP. This study used an open-label, randomized, controlled trial protocol. A group of 100 patients were enrolled in the study and randomly allocated into two comparative groups. Group A (n = 50) received the epidural (interlaminar) approach-2 ultrasound-guided injections as control intervention (each containing two doses of ACS-8 mL). Group B (n = 50) received the perineural (periarticular) approach-2 ultrasound-guided injections as experimental intervention at 7-day intervals (the same volume of ACS). Assessments consisted of an initial assessment (IA) and control assessments at 4 (T1), 12 (T2), and 24 (T3) weeks after the last intervention. Primary outcomes comprised Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), Roland Morris Questionnaire (RMQ), and Euro Quality of Life-5 Dimensions-5 Levels (EQ-5D-5L): Index, Visual Analogue Scale (VAS), and Level Sum Score (LSS). Secondary outcomes included differences between groups in specific endpoints for the above-mentioned questionnaires. In conclusion, this study revealed that both perineural (periarticular) and epidural ACS injections tended to perform in a very similar way. Both routes of Orthokine application show significant improvement in the primary clinical parameters, such as pain and disability, and therefore, both methods can be considered equally effective in managing LBP due to LDDD.

Physiotherapy research on low back pain in the indian context: A bibliometric analysis using the scopus database

BACKGROUND

Low back pain (LBP) is a common musculoskeletal condition that necessitates public health concerns. It also attracts considerable research interest among physiotherapists.

OBJECTIVE

This study conducted a bibliometric analysis to reveal the affinity of Indian physiotherapists toward research on LBP using the Scopus database.

METHODS

An electronic search was performed on December 23, 2020, using specific keywords. The data was downloaded in a Scopus plain text file (.txt) format and were analyzed using R studio (biblioshiny) software.

RESULTS

Two hundred and thirteen articles concerning LBP published from 2003 to 2020 were retrieved from the Scopus database. Among those articles (N= 213), 85.45% (n= 182) were published between 2011 and 2020. An article published by "James SL (2018)" in the Lancet had the highest citation of 1439. The highest collaboration was between India and the United Kingdom, and India and the United States of America jointly accounted for 12.2% (n= 26) of the entire articles (N= 213).

CONCLUSION

Indian physiotherapists have shown an interest through gradually increasing their research output on LBP since 2015. They contributed effectively to various journals and international collaboration. Nevertheless, there is room to improve the quality and quantity of LBP articles in high-quality journals, thereby enhancing the citation count. This study recommends improving the scientific output of Indian physiotherapists on LBP by expanding their international networks.

Global perceived improvement and health-related quality of life after physical therapy in Lebanese patients with chronic non-specific low back pain

BACKGROUND

The effectiveness of physical therapy (PT) in patients with chronic non-specific low back pain (CNSLBP) is mainly evaluated through pain, disability, and health-related quality of life (HRQOL). However, recent studies have recommended the consideration of improvement from patients' perspectives.

OBJECTIVE

This study aimed to investigate the relationship between the global perception of improvement in Lebanese patients with CNSLBP who have undergone PT, the HRQOL levels, as well as pain intensity.

METHODS

132 patients with CNSLBP who have undergone PT completed a questionnaire consisting of sociodemographic and CNSLBP characteristics questions, pain intensity numeric scale (NRS), 12-Item Short-Form Health Survey (SF-12), and the Global Perceived Effect scale (GPE). Binary logistic regressions and Pearson correlation coefficient were used for analyses.

RESULTS

Global perceived improvement of PT varies according to HRQOL levels. A significant correlation was found between pain intensity after PT, perceived improvement from PT, and HRQOL. Educational level and pain irradiation have been shown to be predictive factors of perceived improvement after PT.

CONCLUSION

Pain and HRQOL are interrelated and contributed to elucidating the global perception of improvement after PT in patients with CNSLBP. The findings suggest that patients' global perception of improvement should be considered in evaluating the benefits of physical therapy in addition to pain and HRQOL.

Exploring the role of respiratory intervention as an effective adjunct tool in the management of chronic low back pain: A scoping systematic review

BACKGROUND

Individuals with chronic low back pain (CLBP) are usually prescribed manual therapy and exercise programs. Respiratory exercise interventions are also recommended by some researchers for CLBP. However, the evidence for the relative effectiveness of these treatments is limited, and the question of which sort of intervention is most suited remains unanswered.

OBJECTIVE

This systematic review aims to evaluate the effectiveness of respiratory interventions in CLBP.

METHODS

A systematic search was performed using databases: PubMed, Web of Science, PEDro, Cochrane Library, and Science Direct. The review was registered in PROSPERO (CRD42021233739).

RESULTS

Seven studies met the inclusion criteria. Out of these, one was of poor, three were of fair, and three were of good qualities. A total of 293 subjects were included in seven studies, the mean age of subjects ranged from 21 to 53 years. The largest effect size was reported for pain (d = 1.5) and maximum inspiratory pressure (d = 1.38). No detrimental effects were reported for any of the intervention programs.

CONCLUSIONS

Since most of the research has been done on pain and MIP, and both of these parameters have revealed significant changes with large effect size, therefore it can be concluded that respiratory interventions improve pain and MIP in CLBP. Owing to the limited number of studies available, a definitive outcome could not be documented for other parameters. Thus, further research is needed to provide a more robust piece of evidence and understanding.

Effectiveness of self-management of dry and wet cupping therapy for low back pain: A systematic review and meta-analysis

BACKGROUND

Low back pain (LBP) can significantly affect a person's quality of life. Cupping has been used to treat LBP. However, various cupping methods are typically included in evaluating the efficacy of cupping therapy. Therefore, the objectives of this study were to evaluate the evidence from the literature regarding the effects of dry and wet cupping therapy on LBP in adults. Dry and wet cupping therapy are analyzed categorically in this study.

METHODS

We searched for randomized clinical trials with cupping in LBP published between 2008 and 2022. In dry or wet cupping clinical studies, pain intensity was assessed using the Visual Analogue Scale and present pain intensity, and the quality of life intensity was measured using the Oswestry disability index.

RESULTS

The 656 studies were identified, of which 10 studies for 690 patients with LBP were included in the meta-analysis. There was a significant reduction in the pain intensity score with present pain intensity using wet cupping therapy (P < .01). In addition, both cupping therapy groups displayed significant Oswestry disability index score reduction compared to the control group (both P < .01). The patients with LBP have a substantial reduction by using wet cupping but have not shown a considerable decrease by using dry cupping (P = .19). In addition, only wet cupping therapy groups displayed a significantly improved quality of life compared to the control group. The study had a very high heterogeneity (I2 > 50%). It means there is no standardization in the treatment protocol in randomized clinical trials. In the meta-regression, there was statistically significant evidence that the number of treatment times and intercepts were related (P < .01).

CONCLUSION

The present meta-analysis shows that wet cupping therapy effectively reduces the pain intensity of LBP. Furthermore, both dry wet cupping therapy improved patients with LBP quality of life.

Radiation Exposure during Fluoroscopy-Guided Ozone Chemonucleolysis for Lumbar Disc Herniation

Introduction: Radiation exposure is a frequent drawback of spinal surgery, even if X-ray guidance plays a pivotal role in improving the accuracy and safety of spinal procedures. Consequently, radiation protection is essential to reduce potential negative biological effects. The aim of this study was to evaluate patients’ radiation exposure, the radiation dose emission during fluoroscopy-guided ozone chemonucleolysis (OCN), and the potential role of patient characteristics. Methods: The radiation dose emission reports were retrospectively evaluated in patients who underwent single-level OCN for lumbar disc herniation. A generalized linear model (GLM) with a gamma distribution and log link function was used to assess the association between radiation emission and patients’ characteristics such as age, sex, BMI, level of disc herniation, disc height, and site of disc herniation. Results: Two hundred and forty OCN cases were analyzed. A safe and low level of radiation exposure was registered during OCN. The median fluoroscopy time for OCN was 26.3 (19.4−35.9) seconds, the median radiation emission dose was 19.3 (13.2−27.3) mGy, and he median kerma area product (KAP) was 0.46 (0.33−0.68) mGy ⋅ m2. The resulting KAP values were highly dependent on patient variables. In particular, sex, obesity, and residual disc height < 50% significantly increased the measured KAP, while levels of disc herniations other than L5-S1 reduced the KAP values. Conclusions: The radiation exposure during OCN is low and quite similar to a simple discography. However, patient characteristics are significantly related to radiation exposure and should be carefully evaluated before planning OCN.

Individualized Exercise in Chronic Non-Specific Low Back Pain: A Systematic Review with Meta-Analysis on the Effects of Exercise Alone or in Combination with Psychological Interventions on Pain and Disability

This systematic review, meta-analysis and meta-regression investigated the effects of individualized interventions, based on exercise alone or combined with psychological treatment, on pain intensity and disability in patients with chronic non-specific low-back-pain. Databases were searched up to January 31, 2022 to retrieve respective randomized controlled trials of individualized and/or personalized and/or stratified exercise interventions with or without psychological treatment compared to any control. Fifty-eight studies (n = 10084) were included. At short-term follow-up (12 weeks), low-certainty evidence for pain intensity (SMD -0.28 [95%CI -0.42 to -0.14]) and very low-certainty evidence for disability (-0.17 [-0.31 to -0.02]) indicates effects of individualized versus active exercises, and very low-certainty evidence for pain intensity (-0.40; [-0.58 to -0.22])), but not (low-certainty evidence) for disability (-0.18; [-0.22 to 0.01]) compared to passive controls. At long-term follow-up (1 year), moderate-certainty evidence for pain intensity (-0.14 [-0.22 to -0.07]) and disability (-0.20 [-0.30 to -0.10]) indicates effects versus passive controls. Sensitivity analyses indicates that the effects on pain, but not on disability (always short-term and versus active treatments) were robust. Pain reduction caused by individualized exercise treatments in combination with psychological interventions (in particular behavioral-cognitive therapies) (-0.28 [-0.42 to -0.14], low certainty) is of clinical importance. Certainty of evidence was downgraded mainly due to evidence of risk of bias, publication bias and inconsistency that could not be explained. Individualized exercise can treat pain and disability in chronic non-specific low-back-pain. The effects at short term are of clinical importance (relative differences versus active 38% and versus passive interventions 77%), especially in regard to the little extra effort to individualize exercise. Sub-group analysis suggests a combination of individualized exercise (especially motor-control based treatments) with behavioral therapy interventions to booster effects. PERSPECTIVE: The relative benefit of individualized exercise therapy on chronic low back pain compared to other active treatments is approximately 38% which is of clinical importance. Still, sustainability of effects (> 12 months) is doubtable. As individualization in exercise therapies is easy to implement, its use should be considered. PROSPERO REGISTRATION: CRD42021247331.

What Does It Take for Research to Be Rehabilitation Research?

Six recommendations to facilitate rehabilitation research and supplement existing research practices were identified. Rehabilitation practice requires research addressing different long-term multi-faceted needs and perspectives of end users, including service users, professionals, politicians, and administrators. Research in rehabilitation should therefore integrate different research traditions and methods. Rehabilitation research with a broad focus is sparse, and most of the research takes its starting point in the biomedical research tradition. Through a nominal group process, we developed recommendations to emphasize important issues in rehabilitation research.

A Backbone-Tracking Passive Exoskeleton to Reduce the Stress on the Low-Back: Proof of Concept Study

Exoskeletons for the low-back have great potential as tools to both prevent low-back pain for healthy subjects and limit its impact for chronic patients. Here, we show a proof-of-concept evaluation of our low-back exoskeleton. Its peculiar feature is the backbone-tracking kinematic structure that allows tracking the motion of the human spine while bending the trunk. This mechanism is implemented with a rigid-yet-elongating structure that does not hinder nor constrain the motion of the wearer while providing assistance. In this work, we show the first prototype we manufactured. It is equipped with a traction spring to assist the wearer during trunk flexion/extension. Then, we report the results of a preliminary test with healthy subjects. We measured a reduction of the mean absolute value for some target muscles - including the erector spinae - when using the exoskeleton for payload manipulation tasks. This was achieved without affecting task performance, measured as task time and joints range of motion. We believe these preliminary results are encouraging, paving the way for a broader experimental campaign to evaluate our exoskeleton.

Evaluation of hematological parameters related to systemic inflammation in acute and subacute/chronic low back pain

Aim: To compare the hematological parameters associated with systemic inflammation between acute and subacute/chronic nonspecific low back pain and to evaluate their diagnostic roles in relation to chronicity in low back pain. Materials & methods: This retrospective case-control study included 150 participants aged 18-65 years with acute nonspecific low back pain, 150 with subacute/chronic nonspecific low back pain, 150 as the control group. Results: Red cell distribution width was significantly higher in the subacute/chronic pain group compared with the acute pain group (p = 0.003), and had a poor diagnostic value for chronicity (cutoff: 11.95, p = 0.003). There were no significant differences in terms of other parameters (p > 0.05). Conclusion: Red cell distribution width has a poor diagnostic value for chronicity in nonspecific low back pain.

The Direct Effect of Magnetic Tape® on Pain and Lower-Extremity Blood Flow in Subjects with Low-Back Pain: A Randomized Clinical Trial

Low-back pain has a high impact on the world population, and solutions are in demand. The behavior of specific physiological processes has been modified using magnetic fields, whether for pain relief, bone consolidation, or improvement of vascularization. The use of tape with magnetic properties could help in these cases. A double-blind randomized clinical trial was designed to use Magnetic Tape^® versus placebo Kinesio tape. Blood flow variables were evaluated using pulsed power Doppler ultrasound. Resistance index, pulsatility index, systolic velocity, and diastolic velocity were measured. The pressure pain threshold was measured using algometry in 22 subjects. The results reveal significant differences between the groups for the pulsation index variable (8.06 [5.16, 20.16] in Magnetic Tape^® versus 5.50 [4.56, 6.64] in Kinesio tape) and lower (0.98 [0.92, 1.02] for Magnetic Tape^® versus 0.99 [0.95, 1.01] for Kinesio tape) in the resistance index variable. The pressure pain threshold variable presented significant differences at multiple levels. The application of Magnetic Tape^® causes immediate effects on blood flow and pain and could be a technique of choice for pain modulation. Further studies would be necessary.

Lumbar Bracing for Chronic Low Back Pain: A Randomized Controlled Trial

PURPOSE

We performed this study to evaluate the effect of back bracing to treat patients with chronic low back pain.

METHODS

This was a prospective, unblinded, randomized controlled trial of 61 adults with uncomplicated chronic low back pain (>12 wks) and imaging findings of degenerative spondylosis, to assess the effectiveness of a semirigid back brace. All study participants received back school instruction. The treatment group also received a lumbar orthosis and was instructed to wear it as needed for symptom relief. At baseline, 6 wks, 12 wks, and 6 mos after intervention, we collected: Numerical Rating Scale to measure pain intensity, Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EuroQol 5-Dimension (EQ-5D) to measure patient-reported function and quality of life.

RESULTS

An interim analysis at the halfway point in enrollment (61 of 120 planned participants) revealed the Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EQ-5D scores in the treatment group to be worse than in the control group, but no significant group differences in Numerical Rating Scale scores. Outcome differences between groups analyzed over time revealed (effect [P]): Pain Disability Questionnaire = 0.84 (0.04); Patient-Reported Outcome Measurement Information System = 0.78 (0.005); EQ-5D = 0.06 (0.01); and Numerical Rating Scale = 0.02 (0.6). We halted the study because continuation was unlikely to produce significant changes to the results.

CONCLUSIONS

In patients with uncomplicated chronic low back pain, a back brace when combined with education and exercise instruction did not provide any pain relief compared with education and exercise instruction alone.

Pharmacological and non-pharmacological treatment approaches to chronic lumbar back pain

Low back pain is a common and important cause of disability. Chronic pain increases disability and cost. In this review, we discuss pharmacological and non-pharmacological treatment approaches for chronic low back pain in the light of current data and guidelines.

Integrated Meditation and Exercise Therapy: A Randomized Controlled Pilot of a Combined Nonpharmacological Intervention Focused on Reducing Disability and Pain in Patients with Chronic Low Back Pain

OBJECTIVE

This pilot trial examined the effects of a combined intervention of mindfulness meditation followed by aerobic walking exercise compared with a control condition in chronic low back pain patients. We hypothesized that meditation before exercise would reduce disability, pain, and anxiety by increasing mindfulness prior to physical activity compared with an audiobook control group.

PARTICIPANTS

Thirty-eight adults completed either meditation and exercise treatment (MedExT) (n=18) or an audiobook control condition (n=20).

SETTING

Duquesne University Exercise Physiology Laboratory.

DESIGN

A pilot, assessor-blinded, randomized controlled trial.

METHODS

Over a 4-week period, participants in the MedExT group performed 12-17 minutes of guided meditation followed by 30 minutes of moderate-intensity walking exercise 5 days per week. Measures of disability, pain, mindfulness, and anxiety were taken at baseline and postintervention. Pain perception measurements were taken daily.

RESULTS

Compared with the control group, we observed larger improvements in disability in the MedExT intervention, although the changes were modest and not statistically significant (mean between-group difference, -1.24; 95% confidence interval [CI], -3.1 to 0.6). For secondary outcome measures, MedExT increased mindfulness (within-group) from pre-intervention to postintervention (P=0.0141). Additionally, mean ratings of low back pain intensity and unpleasantness significantly improved with time for the MedExT group compared with that of the control group, respectively (intensity P=0.0008; unpleasantness P=0.0022).

CONCLUSION

. Overall, 4 weeks of MedExT produced suggestive between-group trends for disability, significant between-group differences for measures of pain, and significant within-group increases in mindfulness.

[Lumbar transforaminal epidural block for treatment of low back pain with radicular pain]

OBJECTIVE

To evaluate the efficacy of lumbar transforaminal epidural block (LTEB) for treatment of low back pain with radicular pain.

METHODS

We retrospectively analyzed the clinical data of 78 patients with low back pain and radicular pain admitted to the Department of Orthopedics of Beijing Chuiyangliu Hospital from March, 2017 to April, 2019. Thirty-three of the patients received treatment with LTEB (LTEB group), and 45 received comprehensive conservative treatment including traction, massage, acupuncture and physiotherapy (control group). The demographic and clinical data of the two groups were compared. The patients were followed up for 3 to 24 months, and numerical rating scale (NRS) and Oswestry disability index (ODI) scores of the patients were evaluated before the treatment and at 2 weeks, 1 month and 3 months after discharge to assess the efficacy of the treatment.

RESULTS

The mean operation time of LTEB was 25.7 7.5 min (15-45 min). After the operation, 5 patients developed weakness of the lower limbs but all recovered within 24-72 h. The patients receiving LTEB all showed significantly decreased NRS scores for low back and radicular pain and ODI scores after the operation (P=0.001). At 2 weeks after the operation, the patients receiving LTEB showed significant relief of low back pain as compared with the patients in the control group (t=2.224, P=0.034), and the difference in NRS scores for low back pain between the two groups tended to diminish over time (F=1.743, P=0.183). Treatment with LTEB resulted in obvious relief of radicular pain and significant reduction of the ODI score of the patients (P < 0.001), and such improvements became more obvious over time after LTEB (P < 0.01).

CONCLUSIONS

As a minimally invasive approach, LTEB is effective for treatment of low back pain with radicular pain and can produce good short-term effects of pain relief and functional improvement.
