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. 相似文献2.

Objective
To determine the feasibility and acceptability of a training programme for peer volunteers to support older adults with chronic low back pain (CLBP) following discharge from physiotherapy.Design
Feasibility study.Setting
Community-based.Participants
17 adults (4 male, 13 female) with CLBP or experience of supporting someone with CLBP enrolled and 12 (2 male, 10 female) completed the volunteer training.Intervention
Volunteers took part in a face-to-face or blended delivery peer support training programme based on the Mental Health Foundation’s “Principles into Practice” and adapted for CLBP by the study team.Main outcome measures
Recruitment/retention rates; demographics; time & resources used to deliver training; training evaluation (questionnaire); knowledge questionnaire, and self-efficacy questionnaire.Results
17 participants enrolled on the training programme (11 face-to-face, 6 blended delivery). 12 (71%) completed the training (73% face-to-face, 67% blended delivery). The training was positively evaluated. All but two participants passed the knowledge quiz at the end of the training, and the majority of self-efficacy scores (90%) were high.Conclusions
It is feasible to develop, implement and evaluate a peer support training programme for the facilitation of CLBP self-management in older adults following discharge from physiotherapy. Blended delivery of training may facilitate the recruitment of greater numbers of peer support volunteers in future studies. Supported self-management of CLBP pain is widely recommended but can be difficult to achieve. Peer support might be a promising method of facilitating CLBP self-management without additional burden to health services, and should be further evaluated in a larger study. 相似文献3.
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. 相似文献

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. 相似文献

Pain neurophysiology education (PNE) is a form of education for patients with chronic low back pain (CLBP). The purpose of this systematic review was to investigate the evidence for PNE in the management of pateints with CLBP. A literature search of MEDLINE, CINAHL and AMED was performed from 1996(01)–2010(09). RCT appraisal and synthesis was assessed using the Cochrane Back Review Group (CBRG) guidelines. The main outcome measures were pain, physical-function, psychological-function, and social-function. Two moderate quality RCTs (n = 122) were included in the final review. According to the CBRG criteria there was very low quality evidence that PNE is beneficial for pain, physical-function, psychological-function, and social-function. Meta-analysis found PNE produced statistically significant but clinically small improvements in short-term pain of 5 mm (0, 10.0 mm) [mean difference (95%CI)] on the 100 mm VAS. This review was limited by the small number of studies (n = 2) that met the inclusion criteria and by the fact that both studies were produced by the same group that published the PNE manual. These factors contributed to the relatively low grading of the evidence. There is a need for more studies investigating PNE by different research groups to support early promising findings. Until then firm clinical recommendations cannot be made. 相似文献

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. 相似文献

Health literacy, the ability to seek, understand and utilise health information, is important for good health. Suboptimal health literacy has been associated with poorer health outcomes in many chronic conditions although this has not been studied in chronic low back pain (CLBP). We examined the health literacy of individuals with CLBP using a mixed methods approach. One-hundred and seventeen adults, comprising 61 with no history of CLBP and 56 with CLBP (28 with low and high disability, respectively, as determined by a median split in Oswestry scores) participated. Data regarding severity of pain, LBP-related disability, fear avoidance, beliefs about LBP and pain catastrophizing were collected using questionnaires. Health literacy was measured using the Short-form Test of Functional Health Literacy in Adults (S-TOFHLA). A sub-sample of 36 participants with CLBP also participated in in-depth interviews to qualitatively explore their beliefs about LBP and experiences in seeking, understanding and using information related to LBP. LBP-related beliefs and behaviours, rather than pain intensity and health literacy skills, were found to be important correlates of disability related to LBP. Individuals with CLBP-high disability had poorer back pain beliefs and increased fear avoidance behaviours relating to physical activity. Health literacy (S-TOFHLA) was not related to LBP beliefs and attitudes. Qualitatively, individuals with CLBP-high disability adopted a more passive coping style and had a pathoanatomic view of their disorder compared to individuals with CLBP-low disability. While all participants with CLBP had adequate health literacy scores (S-TOFHLA), qualitative data highlighted difficulties in seeking, understanding and utilising LBP information. 相似文献

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. 相似文献

The relation between cognitive factors and levels of pain and disability in chronic low back pain patients presenting for physiotherapy 总被引:1,自引:0,他引:1

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. 相似文献

BackgroundIndividuals with chronic low back pain (cLBP) may benefit from multimodal functional restoration programs (FRPs).ObjectiveThe aim of this study was to analyze characteristics of individuals with cLBP who were referred or not to an FRP. Because cLBP is a bio-psycho-social disorder, medical and social parameters were analysed.MethodsThis was an observational cross-sectional study performed in 2017 in 6 tertiary centres in France. Consecutive individuals with cLBP visiting a rheumatologist or physical medicine and rehabilitation physician were included. Individuals referred or not to an FRP were compared by demographic characteristics, duration of sick leave over the past year, self-reported physical activity > 1 h/week, pain (numeric rating scale 0–10), anxiety/depression (Hospital Anxiety and Depression Scale), disability (Oswestry Disability Index) and kinesiophobia (Tampa Kinesiophobia Scale). Univariate and multivariate logistic regression analyses were performed, estimating odds ratios (ORs) and 95% confidence intervals (CIs).ResultsWe included 147 individuals with cLBP. The mean (SD) age was 49 (12) years and 88 (60%) were women; 58 (38%) were referred to an FRP. On multivariate analysis, referral to an FRP was associated with reduced pain level (OR: 0.95, 95% CI: 0.91–0.99, for each 1-point increase in pain score), self-reported lack of physical activity (OR: 0.84, 95% CI: 0.72–0.98) and longer sick leave (OR: 1.03, 95% CI: 1.01–1.05, for 30 more days of sick leave).ConclusionIn this multicentric observational study, referral to an FRP was linked to pain, self-reported physical activity and sick leave but not medical characteristics assessed. These findings confirm the bio-psycho-social approach of FRPs for cLBP. 相似文献

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. 相似文献

It has been proposed that patients with chronic non-specific low back pain (CNSLBP) can be broadly classified based on clinical features that represent either predominantly a mechanical pain (MP) or non-mechanical pain (NMP) profile. The aim of this study was to establish if patients with CNSLBP who report features of NMP demonstrate differences in pain thresholds compared to those who report MP characteristics and pain-free controls. This study was a cross-sectional design investigating whether pressure pain threshold (PPT) and/or cold pain threshold (CPT) at three anatomical locations differed between patients with mechanical CNSLBP (n = 17) versus non-mechanical CNSLBP (n = 19 and healthy controls (n = 19) whilst controlling for confounders. The results of this study provide evidence of increased CPT at the wrist in the NMP profile group compared to both the MP profile and control subjects, when controlling for gender, sleep and depression (NMP versus MP group Odds Ratio (OR): 18.4, 95% confidence interval (CI): 2.5–133.1, p = 0.004). There was no evidence of lowered PPT at any site after adjustment for confounding factors. Those with an MP profile had similar pain thresholds to pain-free controls, whereas the NMP profile group demonstrated elevated CPT's consistent with central amplification of pain. These findings may represent different pain mechanisms associated with these patient profiles and may have implications for targeted management. 相似文献

The aim of the present study was to compare the subjectively reported and objectively assessed activity‐related characteristics of patients with Chronic Low Back Pain (CLBP) who were classified according to their scores on the Patterns of Activity Measure‐Pain (POAM‐P) into avoiders, persisters, mixed performers (i.e. high scores on both avoidance and persistence behaviour) or functional performers (i.e. low scores on avoidance and persistence behaviour). Patients carried an electronic diary during 14 days to assess the self‐reported activity and pain intensity levels in daily life. An accelerometer was used to objectively assess their activity level during the same time period. Results were available for 79 patients. Avoiders, persisters and mixed performers showed a higher level of self‐reported disability than functional performers. Avoiders were characterized by a low level of self‐reported habitual activities and persisters by long objectively measured daily uptime. The objectively assessed level of physical activity did not differ between the four groups. A further analysis tested the association between pain intensity levels and self‐reported and objectively assessed daily life activity levels in avoiders and persisters. In persisters, a higher level of self‐reported activities in daily life was related to increased pain. The objectively assessed activity level was not associated with pain intensity. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

We sought to systematically analyze the influence of dose of pain rehabilitation programs (PRPs) for patients with chronic low back pain (CLBP) on disability, work participation, and quality of life (QoL). Literature searches were performed in PubMed, Cochrane Library, Cinahl, and Embase up to October 2012, using MeSH terms, other relevant terms and free-text words. Randomized controlled trials in English, Dutch, and German, analyzing the effect of PRPs, were included. One of the analyzed interventions had to be a PRP. Outcomes should be reported regarding disability, work participation, or QoL. To analyze dose, the number of contact hours should be reported. Two reviewers independently selected titles, abstracts, and full-text articles on the basis of inclusion and exclusion criteria. Data were extracted and risk of bias was assessed. Effect sizes (ES) were calculated for each intervention, and influence of dose variables was analyzed by a mixed model analysis. Eighteen studies were identified, reporting a wide variety of dose variables and contents of PRPs. Analyses showed that evaluation moment, number of disciplines, type of intervention, duration of intervention in weeks, percentage of women, and age influenced the outcomes of PRPs. The independent effect of dose variables could not be distinguished from content because these variables were strongly associated. Because dose variables were never studied separately or reported independently, we were not able to disentangle the relationship between dose, content, and effects of PRPs on disability, work participation, and QoL. 相似文献

Using latent class analysis (LCA), a previous study on patients attending primary care identified four courses of low back pain (LBP) over the subsequent 6 months. To date, no studies have used longitudinal pain recordings to examine the “natural” course of recurrent and chronic LBP in a population-based sample of individuals. This study examines the course of LBP in the general population and elaborates on the stability and criterion-related validity of the clusters derived. A random sample of 400 individuals reporting LBP in a population-based study was asked to complete a comprehensive questionnaire at the start and end of the year’s survey, and 52 weekly pain diaries in between. The latter were analyzed using LCA. 305 individuals returned more than 50% of the diaries. Four clusters were identified (severe persistent, moderate persistent, mild persistent, and fluctuating). The clusters differed significantly with regards to pain and disability. Assessment of cluster stability showed that a considerable proportion of patients in the “fluctuating” group changed their classification over time. Three of the four clusters describing the typical course of pain matched the clusters described previously for patients in primary care. Due to the population-based design, this study achieves, for the first time, a close insight into the “natural” course of chronic and recurrent low back pain, including individuals that did not necessarily visit the general practitioner. The findings will help to understand better the nature of this pain in the general population. 相似文献
