Neurodynamic exercises provide no additional benefit to extension-oriented exercises in people with chronic low back-related leg pain and a directional preference: A randomized clinical trial

BackgroundChronic low back-related leg pain may involve mixed pain mechanisms. A strategy to address both neuropathic and nociceptive pain symptoms would be combining treatments.ObjectiveTo assess the effects of adding neurodynamic exercises to extension-oriented exercises in patients with chronic low back-related leg pain and a directional preference.DesignTwo arm, single blind, randomized clinical trial.MethodEligible participants were aged between 18 and 65 years, had low back pain radiating below gluteus for at least 3 months, pain intensity greater than 3 points in the numerical pain rating scale, positive SLR test and a directional preference for lumbar extension movements. Thirty-one participants were randomly allocated into one of two groups: extension-oriented exercises (EE) or extension exercises plus neurodynamic exercises (EEN). Primary outcomes were leg pain intensity and function at 3 weeks. Secondary outcomes were low back pain intensity, disability, global perceived effect and quality of life at 3 weeks and at 1 month.ResultsRetention rate was 100% (n = 14) in EE and 94% (n = 16) in EEN for primary outcome analysis. There was no between-group difference for the primary outcomes and for low back pain intensity, GPE and quality of life at 3 weeks. For some outcomes, EE was superior to EEN.ConclusionsWe found no benefits in adding neurodynamic exercises to extension-oriented exercises for patients with nerve-related leg pain and a directional preference. As this study has a small and very specific sample, results may be interpreted with caution.     

Stabilisation exercises for low back pain: a systematic review

Objectives

To examine the literature to determine if stabilisation exercises are effective for the treatment of pain and dysfunction in patients with low back pain.

Data sources

PubMed (MEDLINE), CINAHL, AMED, PEDro and the Cochrane Library were searched up to October 2006.

Review methods

Inclusion criteria were: randomised clinical trials; in English; full publications; subjects were adults with low back pain; one group received specific stabilisation exercises as the primary intervention; and outcome measures included some measure of pain and/or function. Following a systematic search of major databases, articles were scored according to the PEDro criteria for quality. Due to heterogeneity of specific interventions, control groups, duration of follow-up, outcome measures and study population, a meta-analysis was not conducted. A qualitative review was undertaken that focused on study quality, study population and type of control group.

Results

In total, 18 trials were included in the review; a large number of trials were excluded. There was little evidence to support the use of stabilisation exercises for acute low back pain. There was some evidence to support the use of stabilisation exercises in chronic back pain, with the majority of high-quality trials showing a significant difference in favour of stabilisation exercises. Overall, however, the evidence was conflicting, and significant differences favouring stabilisation exercises were less likely when they were compared with active treatment control groups rather than inactive control groups.

Conclusions

There may be a role for specific stabilisation exercises in some patients with chronic low back pain, but these are no more effective than other active interventions.     

Aerobic exercise training in addition to conventional physiotherapy for chronic low back pain: a randomized controlled trial

Chan CW, Mok NW, Yeung EW. Aerobic exercise training in addition to conventional physiotherapy for chronic low back pain: a randomized controlled trial.

Objective

To examine the effect of adding aerobic exercise to conventional physiotherapy treatment for patients with chronic low back pain (LBP) in reducing pain and disability.

Design

Randomized controlled trial.

Setting

A physiotherapy outpatient setting in Hong Kong.

Participants

Patients with chronic LBP (N=46) were recruited and randomly assigned to either a control (n=22) or an intervention (n=24) group.

Interventions

An 8-week intervention; both groups received conventional physiotherapy with additional individually tailored aerobic exercise prescribed only to the intervention group.

Main Outcome Measures

Visual analog pain scale, Aberdeen Low Back Pain Disability Scale, and physical fitness measurements were taken at baseline, 8 weeks, and 12 months from the commencement of the intervention. Multivariate analysis of variance was performed to examine between-group differences.

Results

Both groups demonstrated a significant reduction in pain (P<.001) and an improvement in disability (P<.001) at 8 weeks and 12 months; however, no differences were observed between groups. There was no significant difference in LBP relapse at 12 months between the 2 groups (χ²=2.30, P=.13).

Conclusions

The addition of aerobic training to conventional physiotherapy treatment did not enhance either short- or long-term improvement of pain and disability in patients with chronic LBP.     

The effects of selective Pilates versus extension-based exercises on rehabilitation of low back pain

Introduction

Chronic non-specific low back pain (LBP) may lead to functional impairment and physical disability. The aim of this study was to compare the effects of selective Pilates (SP) and extension-based (EB) exercises on pain, lumbar spine curvature, lumbar forward flexion range of motion (ROM), and physical disability in such individuals.

Effectiveness of graded activity versus physiotherapy in patients with chronic nonspecific low back pain: midterm follow up results of a randomized controlled trial

Background

Low back pain (LBP) is a major health and economic problem worldwide. Graded activity and physiotherapy are commonly used interventions for nonspecific low back pain. However, there is currently little evidence to support the use of one intervention over the other in the medium-term.

Immediate effects of kinesio taping on pain and postural stability in patients with chronic low back pain

Objective

Postural control of patients with chronic low back pain (CLBP) is usually impaired. Effects of treatment applications on postural stability have not been well investigated. The aim of this study was to investigate the immediate effects of kinesio taping on pain and postural stability in patients with CLBP.

Enhancing function in older adults with chronic low back pain: a pilot study of endurance training

OBJECTIVES: To assess the effectiveness of a bicycle endurance program in older adults with chronic low back pain (CLBP) and to identify correlates of exercise adherence. DESIGN: Prospective cohort. SETTING: Residential facilities and a tertiary care hospital. PARTICIPANTS: Adults with CLBP aged 55 years and older. Of 29 subjects who agreed to participate, 3 (10%) were deemed ineligible at baseline. Nineteen subjects (73%) were women, and the median age was 72 years. INTERVENTIONS: Subjects were assessed at baseline and at 6 and 12 weeks by using standardized questionnaires, physical examination, and endurance testing by a physical therapist. Subjects received a bicycle and instructions to exercise 3 times a week for 12 weeks at a set wattage. A trained rescarcher collected exercise data weekly.Main outcome measures The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), the lumbar spinal stenosis symptom severity and function scales, and kilocalories were used to assess change. RESULTS: At baseline, subjects were moderately impaired (mean SF-36 physical function score, 52.6). Eighteen (65%) completed the trial. At 12 weeks, physical functioning (SF-36) improved by 11%, mental health (Mental Health Inventory 5-Item Questionnaire) improved by 14%, and CLBP symptoms decreased by 8%. Reasons for withdrawing included illness, family issues, and bicycle-related discomfort. CONCLUSIONS: The bicycle program was safe and effective for improving functional status and well-being.     

How to explain central sensitization to patients with 'unexplained' chronic musculoskeletal pain: practice guidelines

Central sensitization provides an evidence-based explanation for many cases of ‘unexplained’ chronic musculoskeletal pain. Prior to commencing rehabilitation in such cases, it is crucial to change maladaptive illness perceptions, to alter maladaptive pain cognitions and to reconceptualise pain. This can be accomplished by patient education about central sensitization and its role in chronic pain, a strategy known as pain physiology education. Pain physiology education is indicated when: 1) the clinical picture is characterized and dominated by central sensitization; and 2) maladaptive illness perceptions are present. Both are prerequisites for commencing pain physiology education. Face-to-face sessions of pain physiology education, in conjunction with written educational material, are effective for changing pain cognitions and improving health status in patients with various chronic musculoskeletal pain disorders. These include patients with chronic low back pain, chronic whiplash, fibromyalgia and chronic fatigue syndrome. After biopsychosocial assessment pain physiology education comprises of a first face-to-face session explaining basic pain physiology and contrasting acute nociception versus chronic pain (Session 1). Written information about pain physiology should be provided as homework in between session 1 and 2. The second session can be used to correct misunderstandings, and to facilitate the transition from knowledge to adaptive pain coping during daily life. Pain physiology education is a continuous process initiated during the educational sessions and continued within both the active treatment and during the longer term rehabilitation program.     

Electromyography-biofeedback for chronic low back pain: A qualitative cohort study

Background and AimsSurface electromyography-biofeedback (sEMG-BF) may reduce the burden of CLBP by improving physical functioning, sleep, pain catastrophizing, anxiety, and depression. This qualitative study investigated the impact of weekly EMG-BF sessions on adults with CLBP.MethodsTwenty-six individuals with CLBP participated in telephone interviews after completing an 8-week virtual sEMG-BF intervention. Trained interviewers conducted the 10-to-15-minute semi-structured interviews to understand participants’ experience with the intervention. Common themes and subthemes were identified and analyzed using MAXQDA 2022 software.ResultsParticipants were predominantly middle-aged females (M = 45, range of 19 – 66) who have had exposure to utilizing conventional therapies such as physical therapy, chiropractor, and massage for the treatment of CLBP. This study focused on participants who reported their experience of the main outcome study which included perceived reductions in CLBP symptoms, including pain and stress, and positive effects on self-awareness and sleep. Three overarching themes emerged and were further divided into subthemes: participants’ involvement (virtual experience, accessibility of device, and future recommendations) perceived benefits (participants gained awareness, recommendations for future treatment, met expectations, and implementation), and desire for flexibility (obstacles and COVID-19 Impact). No adverse effects were reported by any of the participants within the study.ConclusionsBoth physical and psychological improvements were reported by participants following an sEMG-BF intervention. Specific implementation procedures and critical barriers were identified. In particular, the ability to receive care for CLBP during the COVID-19 pandemic was important to participants.     

Predictive factors for progression through the difficulty levels of Pilates exercises in patients with low back pain: a secondary analysis of a randomized controlled trial

Background

The progression through the difficulty levels of Pilates exercises is a subjective criterion, that depends on the therapist's experience and ability to identify the best moment to progress to the next level.

Treating non-specific chronic low back pain through the Pilates Method

The goal of this study is to review and analyze scientific articles where the Pilates Method was used as treatment for non-specific chronic low back pain (CLBP). Articles were searched using the Medline, EMBASE, PEDro, CINAHL, and SPORTDICUS databases. The criteria used for inclusion were randomized controlled trials (RCT) and clinical controlled trials (CCT) published in English where therapeutic treatment was based on the Pilates Method. The analysis was carried out by two independent reviewers using the PEDro and Jadad Scales. Two RCTs and one CCT were selected for a retrospective analysis. The results of the studies analyzed all demonstrate positive effects, such as improved general function and reduction in pain when applying the Pilates Method in treating non-specific CLBP in adults. However, further research is required to determine which specific parameters are to be applied when prescribing exercises based on the Pilates Method with patients suffering from non-specific CLBP. Finally, we believe that more studies must be carried out where the samples are more widespread so as to give a larger representation and more reliable results.     

Analyzing chronic low back pain: the relative contribution of pain coping strategies

Sixty-two chronic low back pain patients were administered the Coping Strategies Questionnaire (CSQ) to assess the frequency of use and perceived effectiveness of a variety of cognitive and behavioral pain coping strategies. Analysis of individual variables revealed that CSQ factors, gender, physical examination findings, and chronicity of pain had significant effects on one or more of a series of pain, psychological distress or behavioral measures. To assess the relative contribution of each of these variables hierarchical stepwise regression analyses were carried out. These analyses revealed that the Helplessness factor of the CSQ explained 50% of the variance in psychological distress (Global Severity Index of the SCL-90R), and 46% of the variance in depression (Beck Depression Inventory). Patients scoring high on this CSQ factor had significantly higher levels of psychological distress. None of the demographic or medical status variables explained a significant proportion of variance in the psychological distress measures. The Diverting Attention and Praying factor of the CSQ explained a moderate (9%), but significant amount of variance in pain report. Patients scoring high on this factor had higher scores on the McGill Pain Questionnaire. Coping strategies were not strongly related to pain behavior measures such as guarding or uptime. A consideration of pain coping strategies may allow one to design pain coping skills training interventions so as to fit the needs of the individual low back pain patient.

The added value of cognitive behavioral therapy for insomnia to current best evidence physical therapy for chronic spinal pain: protocol of a randomized controlled clinical trial

Background

Insomnia is a highly prevalent and debilitating comorbidity that is often not addressed in therapy for chronic spinal pain (CSP). Given the close interaction between insomnia and CSP severity and related disability, targeting sleep problems during therapy could improve treatment outcomes in these patients.

Chronic migraine and chronic tension-type headache are associated with concomitant low back pain: Results of the German Headache Consortium study

The objective of this study was to evaluate the association between low and frequent low back pain and chronic migraine (CM) and chronic tension-type headache (CTTH) in a large, German population-based sample. Headaches were diagnosed according to International Classification of Headache Disorders-2 criteria and categorized according to frequency (episodic 1–14 days/month or chronic ?15 days/month) and headache type (migraine or TTH). We defined frequent low back pain as self-reported low back pain on ?15 days/month. We calculated odds ratios and 95% confidence intervals (CI) using logistic regression analyses, adjusting for sociodemographic covariates. There were 5605 respondents who reported headache in the previous year, of whom 255 (4.5%) had Chronic Headache. Migraine was diagnosed in 2933 respondents, of whom 182 (6.2%) had CM. TTH was diagnosed in 1253 respondents, of whom 50 (4.0%) had CTTH. Among 9944 respondents, 6030 reported low back pain, of whom 1267 (21.0%) reported frequent low back pain. In adjusted models, the odds of having frequent low back pain were between 2.1 (95% CI 1.7-2.6) and 2.7 (95% CI 2.3-3.2) times higher in all episodic headache subtypes when compared to No Headache. The odds of having frequent low back pain were between 13.7 (95% CI 7.4-25.3) and 18.3 (95% CI 11.9-28.0) times higher in all chronic headache subtypes when compared to No Headache. Low and frequent low back pain was associated with CM and CTTH. Multiple explanations may contribute to the association of headache and back pain, including the notion that the neurobiology of chronic headache, independent of primary headache type, not only involves the trigeminal pain pathway, but is also a part of abnormal general pain processing.     

Effectiveness of focused meditation for patients with chronic low back pain—A randomized controlled clinical trial

ObjectivesWe aimed to evaluate the effectiveness of an 8-week meditation program (focused meditation) in patients with chronic low-back pain.DesignA randomized clinical trial was conducted on 68 patients (55 years;75% female) with chronic low-back pain who scored >40 mm on a 100 mm Visual-Analogue-Scale. Subjects were allocated to an 8-week meditation program (focused meditation) with weekly 75 min classes or to a self-care exercise program with a wait-list offer for meditation. Both groups were instructed to practice at home. Outcomes were assessed baseline and after 4 and 8 weeks. The primary outcome measure was the change in mean back pain at rest after 8 weeks. Secondary outcomes included function, pain-related bothersomeness, perceived stress, quality-of-life (QOL), and psychological outcomes.ResultsTwelve (meditation) and 4 (exercise) patients were lost to follow-up. The primary outcome, pain at rest after 8 weeks, was reduced from 59.3 ± 13.9 mm to 40.8 ± 21.8 mm with meditation vs. 52.9 ± 11.8 mm to 37.3 ± 18.2 mm with exercise (adjusted group difference: −1.4 (95%CI:11.6;8.8;p = n.s.) Perceived stress was significantly more reduced with meditation (p = 0.011). No significant treatment effects were found for other secondary outcomes as pain-related bothersomeness, function, quality-of-life and psychological scores, although the meditation group consistently showed non-significant better improvements compared to the exercise group.ConclusionsFocused meditation and self-care exercise lead to comparable, symptomatic improvements in patients with chronic low back pain. Future studies should include longer-term follow-ups and develop guided meditation programs to support compliance.
