The relation between cognitive factors and levels of pain and disability in chronic low back pain patients presenting for physiotherapy

The aim of this study was to determine the extent to which a number of distinct cognitive factors were differentially related to the levels of pain and disability reported by 183 chronic low back pain (CLBP) patients presenting for physiotherapy. After adjusting for demographics, the cognitive factors accounted for an additional 30% of the variance in pain intensity, with functional self-efficacy (beta=-0.40; P<0.001) and catastrophizing (beta=0.21; P<0.01) both uniquely contributing to the prediction of outcome. The cognitive factors also explained an additional 32% of the variance in disability after adjusting for demographics and pain intensity (total R(2)=0.61). Higher levels of functional self-efficacy (beta=-0.43; P<0.001) and lower levels of depression (beta=0.23; P<0.01) were uniquely related to lower levels of disability. Our findings clearly show that there is a strong association between cognitive factors and the levels of pain and disability reported by CLBP patients presenting for physiotherapy. Functional self-efficacy emerged as a particularly strong predictor of both pain intensity and disability. In view of our findings it would seem that targeting specific cognitive factors should be an integral facet of physiotherapy-based treatments for CLBP.     

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.     

Natural course of acute neck and low back pain in the general population: The HUNT study

In this prospective cohort study we aimed to describe the natural course of acute neck and low back pain in a general population of Norway. We screened 9056 subjects aged 20–67 years who participated in a general health survey for a new episode of neck or low back pain the previous month. The screening identified 219 subjects who formed the cohort for this study. Pain intensity was reported on a numeric rating scale (0–10) at 1, 2, 3, 6, and 12 months after start of the new pain episode. The course of pain was described for neck and low back pain, different baseline pain levels, age groups, and number of pain sites at baseline. Use of medication and health care was described and associations between pain intensity and seeking health care were estimated. Pain declined rapidly within 1 month after a new pain episode, with a reduction of 0.91 (95% confidence interval [CI] 0.50–1.32) for neck pain and 1.40 (95% CI 0.82–1.99) for low back pain with little change thereafter. However, pain remained unchanged over the follow-up year for those with equal pain in the neck and low back areas at baseline and for those reporting 4 or more pain sites at baseline. Only 1 in 5 sought health care for their complaints. Still, the course of pain was comparable to effect sizes reported in interventional studies. This study thus contributes natural course reference data for comparisons of pain outcome in clinical trials and practice.     

Patient-centredness in physiotherapy from the perspective of the chronic low back pain patient

Objective

To define patient-centredness from the patient's perspective in the context of physiotherapy for chronic low back pain (CLBP).

Design

Qualitative study using semi-structured interviews to explore perceptions of various aspects of physiotherapy management of CLBP.

Setting

Physiotherapy departments in one geographical area of the UK National Health Service.

Participants

Twenty-five individuals who had received physiotherapy for CLBP within the previous 6 months.

Results

Six key themes emerged as the dimensions that the participants perceived to be important for patient-centred physiotherapy: communication; individual care; decision-making; information; the physiotherapist; and organisation of care. Communication was the most important dimension, underpinning the five other dimensions as well as being a distinct dimension of patient-centred physiotherapy.

Conclusions

Physiotherapists should have an understanding of the six dimensions of patient-centred physiotherapy for CLBP. Improving physiotherapists’ communication skills may better facilitate patient-centred physiotherapy, and therefore enhance the experience of physiotherapy for this client group.     

Acute low back pain: clinical course and prognostic factors

Purpose.?The aim of this study was to assess the clinical course of patients with acute low back pain (LBP) throughout 12 weeks and to identify the prognostic factors for non-recovery in the short term.

Method.?A total of 91 patients with acute LBP (<3 weeks) were included in this study. Baseline assessments including demographic variables, clinical characteristics of pain, lost work time and results of clinical examination were noted. Pain intensity, disability, general health perception and depression were assessed according to visual analogue scale, Roland Morris Disability Questionnaire (RMDQ), Nottingham Health Profile (NHP) and Beck Depression Inventory, respectively. Patients were assessed for pain intensity and disability at baseline, and at 1, 2, 4, 8 and 12 weeks of follow-up. Recovery was considered if patients scored <4 on the RMDQ and pain had resolved. At the 2nd week of follow-up, patients were divided into two groups according to recovery (Group 1) or non-recovery (Group 2) to identify the prognostic factors, which were analysed by multiple logistic regression.

Results.?At 2 weeks, 52 (57.1%) of the patients had recovered and only eight (8.7%) developed chronic LBP. Mean pain intensity and mean disability scores dropped 96.7 and 96.4%, respectively, of initial levels during the 12 weeks. Sixty per cent of 63 employed patients reported lost time from work. A comparison between groups revealed that finger-floor distance, RMDQ and NHP (pain, physical mobility, emotional reactions, sleep, energy level, and distress subgroups) were statistically significantly lower in Group 1, and NHP-pain was strongly associated with non-recovery in the short term.

Conclusions.?Acute LBP patients with disability generally recover in the first weeks. General health perception (NHP) – pain subgroup score was identified in particular as the best prognostic factor for non-recovery in the short term. Hence, pain should be given particular consideration in baseline assessments of acute LBP patients.     

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.     

Disuse and deconditioning in chronic low back pain: concepts and hypotheses on contributing mechanisms.

For years enhancement of a patient's level of physical fitness has been an important goal in rehabilitation treatment in chronic low back pain (CLBP), based on the hypothesis that physical deconditioning contributes to the chronicity of low back pain. However, whether this hypothesis in CLBP holds is not clear. In this paper, possible mechanisms that contribute to the development of physical deconditioning in CLBP, such as avoidance behaviour and suppressive behaviour, are discussed. The presence of both deconditioning-related physiological changes, such as muscle atrophy, changes in metabolism, osteoporosis and obesity as well as deconditioning related functional changes, such as a decrease in cardiovascular capacity, a decrease in muscle strength and impaired motor control in patients with CLBP are discussed. Results of studies on the level of physical activities in daily life (PAL) and the level of physical fitness in patients with CLBP compared to healthy controls were reviewed. In studies on PAL results that were either lower or comparable to healthy subjects were found. The presence of disuse (i.e., a decrease in the level of physical activities in daily life) in patients with CLBP was not confirmed. The inconclusive findings in the papers reviewed may partly be explained by different measurement methods used in research on PAL in chronic pain. The level of physical fitness of CLBP patients also appeared to be lower or comparable to the fitness level of healthy persons. A discriminating factor between fit and unfit patients with back pain may be the fact that fit persons more frequently are still employed, and as such may be involved more in physical activity. Lastly some suggestions are made for further research in the field of disuse and deconditioning in CLBP.     

Relationships between forward head posture and lumbopelvic sagittal alignment in older adults with chronic low back pain

BackgroundAbnormal posture creates abnormal stress and strain in many spinal structures which are considered predisposing factors for chronic mechanical low back pain.PurposeTo examine the relationships among pain intensity, forward head posture (decreased craniovertebral angle) and lumbopelvic sagittal alignment (pelvic incidence, pelvic tilt, sacral slope, and lumbar lordosis) in chronic mechanical low back pain patients.MethodsA cross-section correlational study was conducted on one hundred patients. A numerical-pain-rating scale was used to determine pain intensity. Standardized standing lateral radiographs were analyzed to measure the spinopelvic angles. Reported data were analyzed using correlation coefficients, and regression analyses.ResultsLumbar lordosis had very strong positive correlations with each pain intensity and sacral slope. Pain intensity had a strong positive correlation with sacral slope. Moderate positive correlations highlighted between pelvic tilt and craniovertebral angle. Moreover, the pelvic incidence had weak positive correlations with each sacral slope and pelvic tilt. Negative correlations were strong between pelvic tilt and each of pain intensity, lumbar lordosis and sacral slope. Craniovertebral angle had moderate negative correlations with each of pain, lumbar lordosis, and sacral slope. However, the pelvic incidence had no relations with pain, craniovertebral angle lumbar lordosis. Overall, an association of demographic data and measured variables had a significant effect on the pain multi-regression equation prediction model. They accounted for 76.60% of the variation in pain.ConclusionAbnormal spinopelvic posture relates to chronic mechanical low back pain. There are significant associations among pain intensity, FHP and lumbopelvic sagittal alignment in chronic mechanical low back pain patients.     

Effects of Qigong practice in office workers with chronic non-specific low back pain: A randomized control trial

ObjectiveTo investigate the effects of Qigong practice, Guan Yin Zi Zai Gong level 1, compared with a waiting list control group among office workers with chronic nonspecific low back pain (CNLBP).MethodsA randomized controlled trial was conducted at offices in the Bangkok Metropolitan Region. Seventy-two office workers with CNLBP were screened for inclusion/exclusion criteria (age 20–40 years; sitting period more than 4 h per day) and were allocated randomly into two groups: the Qigong and waiting list groups (n = 36 each). The participants in the Qigong group took a Qigong practice class (Guan Yin Zi Zai Gong level 1) for one hour per week for six weeks at their workstation. The participants were encouraged to conduct the Qigong exercise at home every day. The waiting list group received general advice regarding low back pain management. The primary outcomes were pain intensity, measured by the visual analog scale, and back functional disability, measured by the Roland and Morris Disability Questionnaire. The secondary outcomes were back range of motion, core stability performance index, heart rate, respiratory rate, the Srithanya Stress Scale (ST-5), and the global perceived effect (GPE) questionnaire.ResultsCompared to the baseline, participants in the Qigong group experienced significantly decreased pain intensity and back functional disability. No statistically significant difference in these parameters was found in the waiting list group. Comparing the two groups, Qigong exercise significantly improved pain intensity, back functional impairment, range of motion, core muscle strength, heart rate, respiratory rate, and mental status. The Qigong group also had a significantly higher global outcome satisfaction than the waiting list group.ConclusionQigong practice is an option for treatment of CNLBP in office workers.     

Cognitive distortion and disability in chronic low back pain

Numerous authors have suggested that cognitions play an important role in the development, maintenance, and treatment of chronic low back pain (CLBP). However, little evidence exists to support the association between cognitive variables and the CLBP problem. The present study examined the relationship of cognitive distortion, as measured by the Cognitive Error Questionnaire, to disability, as measured by the Sickness Impact Profile, in a sample of 138 CLBP patients. As predicted, cognitive distortion was consistently related to several aspects of disability. The cognitive variables accounted for variance in disability beyond that accounted for by severity of pain, number of pain treatments, and depression. Also as predicted, cognitive distortion concerning low back pain situations was more closely correlated with disability than was distortion concerning general, nonpain situations. Overgeneralization was the specific cognitive error most closely and consistently correlated with disability. The results are interpreted as consistent with a cognitive-behavioral model of CLBP.The authors would like to thank Holly Waldron, Dennis Turk, and several anonymous reviewers for their comments on an earlier version of this paper.     

The effect of the Alexander Technique on pain intensity in patients with chronic low back pain: A randomized controlled trial

ObjectiveThe present study was performed to determine the effect of the Alexander Technique on the intensity of pain in patients with chronic low back pain (LBP).MethodsThis study is a clinical trial that was performed on 80 patients with chronic LBP in Kashan, Iran. Participants were randomly assigned in control and intervention groups. To assess the participants’ LBP, a visual analog scale of pain (VAS-Pain) was completed by both groups. In the intervention group, in addition to routine care for LBP patients, the Alexander Technique was performed in three 60-min sessions per week for 12 weeks. The control group participants received routine care for LBP patients. The two groups completed the VAS-Pain scale immediately after and one month after the intervention.ResultsThe results showed that there was no statistically significant difference between the two groups in terms of demographic characteristics and mean pain intensity score before the intervention (p > 0.05). Immediately after and then one month after the intervention, there was statistically significant differences between the two groups regarding the mean scores of pain (p < 0.05). The results of repeated measures ANOVA showed that, in the intervention group, the mean score of pain had decreased over time (p < 0.05).ConclusionThe results of the present study showed that the Alexander Technique was effective in reducing the intensity of pain among the participants. We recommend the Alexander Technique as a useful and effective intervention for reducing chronic LBP.     

A randomised controlled study of reflexology for the management of chronic low back pain

The use of complementary and alternative medicine (CAM) for the management of chronic low back pain (CLBP) continues to rise. However, questions regarding the efficacy of many CAM therapies for CLBP remain unresolved. The present study investigated the effectiveness of reflexology for CLBP. A pragmatic randomised controlled trial was conducted. N=243 patients were randomised to one of three groups: reflexology, relaxation, or non-intervention (usual care). All completed a questionnaire booklet before and after the treatment phase, and at six months follow up. This measured their general health status, pain, functioning, coping strategies and mood. After adjusting for pre-treatment scores repeated measures ANCOVA found no significant differences between the groups pre and post treatment on the primary outcome measures of pain and functioning. There was a main effect of pain reduction, irrespective of group. Trends in the data illustrated the pain reduction was greatest in the reflexology group. Thus, the current study does not indicate that adding reflexology to usual GP care for the management of CLBP is any more effective than usual GP care alone.     

The effect of chronic low back pain on size and contraction of the lumbar multifidus muscle

Decreases in the size of the multifidus muscle have been consistently documented in people with low back pain. Recently, ultrasound imaging techniques have been used to measure contraction size of the multifidus muscle, via comparison of the thickness of the muscle at rest and on contraction. The aim of this study was to compare both the size (cross-sectional area, CSA) and the ability to voluntarily perform an isometric contraction of the multifidus muscle at four vertebral levels in 34 subjects with and without chronic low back pain (CLBP). Ultrasound imaging was used for assessments, conducted by independent examiners. Results showed a significantly smaller CSA of the multifidus muscle for the subjects in the CLBP group compared with subjects from the healthy group at the L5 vertebral level (F = 29.1, p = 0.001) and a significantly smaller percent thickness contraction for subjects of the CLBP group at the same vertebral level (F = 6.6, p = 0.02). This result was not present at other vertebral levels (p > 0.05). The results of this study support previous findings that the pattern of multifidus muscle atrophy in CLBP patients is localized rather than generalized but also provided evidence of a corresponding reduced ability to voluntarily contract the atrophied muscle.     

The effects of a back rehabilitation programme for patients with chronic low back pain

AIM: The aim of this paper was to perform a pragmatic before-after analysis of a back rehabilitation programme (BRP) for patients with chronic low back pain (LBP). A total of 877 patients were recruited onto the BRP, which were carried out at four centres within the Wrightington, Wigan and Leigh NHS Trust. The BRP consisted of nine 2-hour group sessions of therapy run over 5 weeks and included 1 hour of exercise and 1 hour of education, advice problem solving and goal setting. METHOD: Using the Wilcoxen signed rank tests and paired t-tests levels of pain, disability, anxiety and depression were significantly reduced pre-post programme (P < 0.001). In addition, the levels of fitness and perceived control improved significantly (P < 0.001) suggesting that participants were better able to manage their LBP. CONCLUSION: Overall, the BRP proved to be effective in reducing pain, disability, anxiety and depression levels for people with chronic LBP. However, despite significant improvements in outcome measures only 50% of the patients completed the BRP and questionnaires post BRP. The implications of the findings are discussed with respect to modified programmes and alternative management for patients within different subgroups of LBP.     

"Being" in pain: the role of self-discrepancies in the emotional experience and activity patterns of patients with chronic low back pain

Chronic pain not only interferes with daily activities, it may also have a negative impact on the perceived integrity of one’s self through self-discrepancies. Self-discrepancies are experienced distances between the actual self and self-guides that can exist from 2 perspectives (ie, own and other). Self-discrepancies are associated with negative mood states and incite self-regulatory behavior in order to reduce these discrepancies. The present study was aimed at replicating the emotional consequences of self-discrepancies in patients with chronic low back pain, and extending current knowledge of the behavioral consequences of self-discrepancies (ie, behavioral activity patterns such as avoidance and persistence). A cross-sectional design was employed with 83 patients who completed a number of self-report measures. We hypothesized that ideal and ought discrepancies, as well as feared congruencies were associated with depressed and anxious mood. On the behavioral level, a U-shaped relationship was hypothesized between ideal and ought self-discrepancies and persistence behavior, whereas feared self-discrepancies were hypothesized to be related to avoidance behavior. Results were partially in line with the hypotheses. With respect to the emotional consequences, feared (own and other) self-discrepancies were predictive of depressive and anxious mood. With regard to activity patterns, results showed a U-shaped relationship between ideal-other self-discrepancies and persistence behavior and a positive relationship between feared-own self-discrepancies and avoidance behavior. In contrast to expectations, none of the other self-discrepancies was related to activity patterns. Of interest was that avoidance, but not persistence behavior, was predictive of higher levels of disability and lower levels of quality of life.     

The immediate effects of neuromuscular joint facilitation on chronic low back pain in young and elderly people

[Purpose] This study aimed to investigate the changes in the pain severity and muscle hardness of the multifidus and longissimus muscles of young and elderly patients with low back pain after neuromuscular joint facilitation treatment. [Participants and Methods] The participants were 13 young patients and 11 elderly patients with chronic low back pain. The neuromuscular joint facilitation lumbar approach was used in all participants. The muscle hardness of the multifidus and longissimus muscles was assessed at the L4 and L5 levels of the lumbar spine. The changes in pain severity of low back pain were assessed using a visual analogue scale before and after treatment. [Results] Visual analogue scale scores significantly decreased in both groups after treatment. The young group showed significant differences in muscle hardness pre- and post-intervention. In addition, except for the muscle hardness of the multifidus muscle before intervention, on the side with pain at the L5 level, longissimus muscle hardness was higher in the elderly, as compared to the young patient group. [Conclusion] Interventions with neuromuscular joint facilitation have an immediate effect on pain relief in young and elderly people with chronic low back pain and on muscle spasms in young people with chronic low back pain.

Efficacy and tolerability of buccal buprenorphine in opioid-naive patients with moderate to severe chronic low back pain

Objectives: Buprenorphine HCl buccal film has been developed for treating chronic pain utilizing BioErodible MucoAdhesive (BEMA^®) delivery technology. Buccal buprenorphine (BBUP; Belbuca^TM, Endo Pharmaceuticals) was evaluated for the management of moderate to severe chronic low back pain (CLBP) requiring around-the-clock analgesia in a multicenter, double-blind, placebo-controlled, enriched-enrollment, randomized-withdrawal study in opioid-naive patients.

Methods: Patients (n = 749) were titrated to a dose of BBUP (range, 150–450 µg every 12 h) that was generally well tolerated and provided adequate analgesia for ≥14 days, and then randomized to BBUP (n = 229) or placebo (n = 232), respectively. The primary efficacy variable was the change from baseline to week 12 of double-blind treatment in the mean of daily average pain intensity scores (numeric rating scale from 0 [no pain] to 10 [worst pain imaginable]).

Results: Patients were experiencing moderate to severe pain at study entry: mean (SD) = 7.15 (1.05). Following titration, pain was reduced to the mild range; 2.81 (1.07). After randomization, mean (SD) pain scores increased from baseline to week 12 more with placebo (1.59 [2.04]) versus BBUP: (0.94 [1.85]) with a significant between-group difference (?0.67 [95% CI: ?1.07 to ?0.26]; p = 0.0012). A significantly larger percentage of patients receiving BBUP versus placebo had ≥30% pain reduction (63% vs 47%; p = 0.0012). During double-blind treatment, the most frequent adverse events (AEs) with BBUP were nausea (10%), constipation (4%) and vomiting (4%). The most common AEs with placebo were nausea (7%), upper respiratory tract infection (4%), headache (3%) and diarrhea (3%).

Conclusions: These findings demonstrate the efficacy and tolerability of BBUP among opioid-naive patients requiring around-the-clock opioid treatment for CLBP.     

Patients’ perceptions of self-management of chronic low back pain: evidence for enhancing patient education and support

Objectives

To explore the extent to which physiotherapy facilitated chronic low back pain (CLBP) patients to self-manage following discharge, and to explore patients’ perceptions of their need for self-management interventions or support and their preferences in terms of delivery.

Design

Qualitative study using semi-structured interviews to explore patients’ perceptions of various aspects of physiotherapy management of CLBP.

Setting

Physiotherapy departments in one geographical area of the UK National Health Service.

Participants

Twenty-five people who had received physiotherapy for CLBP within the previous 6 months.

Results

Adoption of self-management strategies was not achieved consistently in this group of participants. There was a strongly perceived need for self-management support following discharge from physiotherapy. Exercises were reportedly the most common self-management strategy in use. However, it was common for participants to perceive that physiotherapy had little influence on their CLBP management following discharge.

Conclusions

These results suggest that CLBP patients could be better facilitated to manage their condition. Providing self-management education in addition to the patient information and education provided traditionally, and providing self-management support in the form of direct access and/or review appointments or telephone calls is worthy of further investigation in this patient group.
