Treatment strategy for chronic low back pain

Biopsychosocial rehabilitation in the working population with chronic low back pain: a concept analysis

OBJECTIVE

To identify the essential attributes of biopsychosocial rehabilitation for chronic low back pain in the working population.

DESIGN

A concept analysis was conducted according to the 8-step method of Walker and Avant. This framework provides a clear concept and theoretical and operational definitions.

METHODS

Five databases were searched, followed by a systematic screening. Subsequently, attributes, illustrative cases, antecedents, consequences and empirical referents were formulated.

RESULTS

Of the 3793 studies identified, 42 unique references were included. Eleven attributes were identified: therapeutic exercise, psychological support, education, personalization, self-management, participation, follow-up, practice standard, goal-setting, social support, and dietary advice. Subsequently, illustrative cases were described. Antecedents, such as motivation, preparedness and a multidisciplinary team, were found, together with consequences such as decreased pain, less sick-leave and increased function and work status. Finally, examples of empirical referents were given.

CONCLUSION

This study identified the attributes that are necessary to develop biopsychosocial rehabilitation intervention programmes for chronic low back pain. The defined concept of biopsychosocial rehabilitation for chronic low back pain may serve as a solid base to further develop and apply interventions. Future research should focus on the objectification of biopsychosocial rehabilitation and conceptualization regarding how personalization is done.

Prevalence and biopsychosocial factors associated with chronic low back pain in urban and rural communities in Western Africa: a population-based door-to-door survey in Benin

PURPOSE

This study aimed to assess the prevalence of chronic low back pain (CLBP) and related biopsychosocial factors in urban and rural communities in Benin.

METHODS

This is a population-based observational cross-sectional survey. An interviewer-administered electronic questionnaire was used to collect information on demographic, socio-economic, behavioral, and psychological factors relating to CLBP risk factors and medical history of participants. The numeric pain rating scale and the Beck Depression Inventory were used to assess pain intensity and the level of depression, respectively. Bivariate analyses were performed to investigate the association between sociodemographic, behavioral, and psychological factors and CLBP. Sequential multiple regression analyses were subsequently performed to predict the occurrence of CLBP.

RESULTS

A total of 4320 participants, with a mean age ± SD of 32.9 ± 13.1 years, of which 40.7% were females and 50.1% from an urban area, were enrolled in the study. We found a global prevalence rate of CLBP of 35.5% [95% CI 34.1-36.9%]. The prevalence in urban areas was 30.68% [95% CI 28.9-32.8%]) while 40.2% was found in rural areas [95% CI 38.1-42.2%]). Age (p < 0.001), level of education (p = 0.046), marital status (p < 0.001), working status (p < 0.003), tobacco use (p < 0.016) and regular physical activity (p < 0.011) were associated with CLBP. In urban areas, only the level of education was able to predict the prevalence of CLBP (R2 = 61%). In rural areas, CLBP was predicted by age, marital and working status (R2 = 89%).

CONCLUSIONS

This study showed a high prevalence of CLBP among urban and rural communities in Benin. Age, level of education, marital status, and working status were significantly associated with CLBP in Benin.

Efficiency of active therapy for low back pain in elderly men

BACKGROUND

Restoration of functionality in patients with low back pain is one of the most important rehabilitation and societal problems. The aim of this study was to verify the results of the DBC (Documentation Based Care) method used in elderly men.

METHOD

This study evaluated the efficiency of DBC treatment on the basis of spinal mobility in sagittal, frontal and transverse planes and a subjective assessment of pain. There were two research groups: one with 187 men over the age of 65, and the other with 187 men under the age of 65. The patients in the study were carefully selected. All subjects suffered from chronic, non-specific low back pain lasting for a period of at least three months.

CONCLUSION

The conducted analyses confirmed that a functional restoration process improved spinal mobility in all planes of movement, decreased pain and functional limitations, and reduced the level of depression.

Can the STarT Back Tool predict health-related quality of life and work ability after an acute/subacute episode with back or neck pain? A psychometric validation study in primary care

OBJECTIVES

The predictive ability of the STarT Back Tool (SBT) has not yet been examined among acute/subacute back and/or neck pain in a primary care setting in respect to health-related quality of life (HRQoL) and work ability outcomes. The aim of this study was to evaluate the SBT's predictive validity for HRQoL and work ability outcomes at long-term follow-up in a population with acute/subacute back and/or neck pain.

SETTING

Prospective data from 35 primary care centres in south Sweden during 2013.

PARTICIPANTS

Patients (n=329) with acute/subacute back and/or neck pain, aged 18-67 years, not on sick leave or <60 days of sick leave completed the SBT when applying for physiotherapy treatment. Long-term follow-up measures (median 13 months, range 11-27 months) of HRQoL (EQ-5D) and work ability (Work Ability Score) was completed by 238 patients (72%).

OUTCOMES

The predictive ability of the SBT for HRQoL and work ability outcomes was examined using Kruskal-Wallis test, logistic regression and area under the curve (AUC).

RESULTS

Based on SBT risk group stratification, 103 (43%), 107 (45%) and 28 (12%) patients were considered as low, medium and at high risk, respectively. There were statistically significant differences in HRQoL (p<0.001) and work ability (p<0.001) at follow-up between all three SBT risk groups. Patients in the high risk group had a significantly increased risk of having poor HRQoL (OR 6.16, 95% CI 1.50 to 25.26) and poor work ability (OR 5.08, 95% CI 1.75 to 14.71) vs the low risk group at follow-up. The AUC was 0.73 (95% CI 0.61 to 0.84) for HRQoL and 0.68 (95% CI 0.61 to 0.76) for work ability.

CONCLUSIONS

The SBT is an appropriate tool for identifying patients with a poor long-term HRQoL and/or work ability outcome in a population with acute/subacute back and/or neck pain, and maybe a useful adjunct to primary care physiotherapy assessment and practice.

Magnetic Resonance Imaging Undetectable Epiduroscopic Hotspot in Chronic Diskogenic Back Pain-Does Sinuvertebral Neuropathy Actually Exist?

BACKGROUND

The causes of chronic diskogenic back pain have not yet been clearly identified. Neural ingrowth around the annulus is widely considered to be one of the possible cause. However, neuropathy around the annulus has yet to be observed visually. We report a case of a hotspot that was observed in an epiduroscopic view, but not in imaging findings.

CASE DESCRIPTION

A 46-year-old woman was admitted with pain in the back, left buttock, and posterior thigh for 2 years. A straight leg raising test was positive on the left side, and left great toe dorsiflexion was decreased to grade 3/5. The Visual Analog Scale pain score was 7/10. On the basis of her symptoms, epidural block, medial branch block, sacroiliac joint block, piriformis muscle injection, physical therapy, and medication were attempted, but no improvement in symptoms was observed. A provocation test was performed at the L3-L4, L4-L5, and L5-S1 intervertebral disks, and severe pain was induced in the L5-S1 intervertebral disk, which was not suspicious on magnetic resonance imaging. We performed transforaminal epiduroscopic laser ablation on L5-S1 and found a hotspot on L5-S1 during the procedure. During laser provocation of the hotspot, the patient complained of severe pain in her lower back and legs, and her pain decreased after ablation of hotspot with laser and improvement in motor weakness was noticed.

CONCLUSION

In this study, we observed annulus hotspots, which have not been observed in imaging studies such as computed tomography or magnetic resonance imaging in patients with chronic back pain and leg pain, and observed remarkable symptom improvement after transforaminal epiduroscopic laser ablation.

Biopsychosocial factors associated with chronic low back pain disability in rural Nigeria: a population-based cross-sectional study

Introduction

Many people in Nigeria are living with disability due to chronic low back pain (CLBP), with the greatest burden accounted for by people living in rural Nigeria. However, factors associated with disability in rural Nigeria have not yet been established. We investigated the biomechanical and psychosocial predictors of CLBP disability in a rural Nigerian population.

Methods

A cross-sectional study of adults with non-specific CLBP recruited from rural communities in Enugu State, South-eastern Nigeria. Measures of self-reported and performance-based disability, pain intensity, anxiety and depression, coping strategies, social support, occupational biomechanical factors, illness perceptions and fear avoidance beliefs were collected by trained community health workers. We used univariate and multivariate analyses.

Results

200 individuals were recruited. Psychosocial factors were the most important factors associated with CLBP disability, and accounted for 62.5% and 49.1% of the variance in self-reported and performance-based disability, respectively. The significant predictors of self-reported disability were: illness perceptions (β=0.289; p<0.0005), pain intensity (β=0.230; p<0.0005), catastrophising (β=0.210; p=0.001), fear avoidance beliefs (β=0.198; p=0.001) and anxiety (β=0.154; p=0.023). The significant predictors of performance-based disability were: illness perceptions (β=0.366; p<0.0005), social support (β=0.290; p<0.0005), fear avoidance beliefs (β=0.189; p<0.01) and female gender (β=0.184; p<0.01). Illness concern was the most salient dimension of illness perceptions predicting self-reported and performance-based disability.

Conclusions

These results provide evidence which can be used to inform the development of interventions to reduce CLBP disability in rural Nigeria, and may have relevance in other rural African contexts.

Application of Primary Care Guideline for Chronic Low Back Pain in the Emergency Department

Chronic low back pain (CLBP) is a primary care condition that overflows into the emergency department (ED). No ED-specific practice guideline exists for the management of patients with CLBP in the ED setting. Back pain is a common chief complaint, with cases of CLBP making up to 50% of the patients seen with back pain in an urban, freestanding ED affiliated with a multicampus health system in the Midwest where 25% of patients live below the poverty line and 21.8% do not have primary care. Kolcaba's Theory of Comfort guides the implementation of an evidence-based practice application project. The Guideline for the Evidence-Informed Primary Care Management of Low Back Pain from the National Guideline Clearinghouse is introduced. Interprofessional collaboration for immediate referrals was implemented. The plan-do-study-act model was applied with descriptive analysis of the data. Reflective of established specific aims of the project, there was increased (1) support for the use of evidence-based practice guideline among the ED providers and staff, (2) use of evidence-based practices, (3) connection of patients to community resources, (4) evidence-based education for patients, and (5) overall satisfaction with pain management. The effectiveness of the application of this primary care guideline in the ED opens the way both for region-wide application of the guidelines and for the introduction of other primary care practice guidelines for patients who present to the ED with other chronic conditions.

Contribution of occupational factors to the incidence and persistence of chronic low back pain among workers: results from the longitudinal VISAT study

OBJECTIVE

Among the aetiological factors of chronic low back pain (CLBP), occupational factors are often suspected, but their contribution remains to be ascertained. This study aimed to determine the impact of a wide range of occupational factors on the incidence and persistence of CLBP.

METHOD

From the VISAT (VIeillissement SAnté Travail) study, 1560 workers were examined at baseline and 5 years later. CLBP was defined as having low back pain or specific treatment for at least 6 months. Participants newly affected with CLBP and those with persistent CLBP at follow-up were distinguished. In addition to individual factors, a broad panel of occupational factors were analysed, covering employment, physical, organisational and psychosocial factors. Multivariate analyses were used to determine predictive factors of incidence and persistence of CLBP. Receiver operating characteristic (ROC) curves were performed to analyse the contribution of occupational factors.

RESULTS

22.6% of participants without any CLBP initially presented with CLBP 5 years later, while 53.7% of participants with CLBP at baseline had CLBP at the second collection. Carrying heavy loads, the lack of recognition of completed work and productivity-related income predicted a higher risk of incidence of CLBP. However, no significant association between occupational factors and the risk for persistence of CLBP was observed, while the risk was multiplied by two for history of depression and rheumatological events. ROC curves confirmed the significant contribution of occupational factors to incidence of CLBP.

CONCLUSIONS

Occupational factors played a pivotal role in the incidence of CLBP, while individual factors were the main determinants of persistence of CLBP.

A pilot study analyzing the effects of Chinese cupping as an adjunct treatment for patients with subacute low back pain on relieving pain, improving range of motion, and improving function

BACKGROUND

Cupping, a classic Chinese medicine treatment, is a technique that applies suction cups over soft tissue. Cupping is gaining popularity in physical medicine because of the simplicity in application, minimal adverse effects, and reduction in pain and muscle tenderness. These factors also make it a cost-effective intervention. For this study, cupping was used to treat low back pain (LBP).

OBJECTIVE

To evaluate the effectiveness of Chinese cupping in acutely reducing pain, decreasing tenderness to palpation, and improving range of motion for patients with subacute or chronic LBP.

PATIENTS/SETTING

Twenty-one patients who reported back pain for at least 8 weeks volunteered at a multidisciplinary holistic outpatient clinic.

INTERVENTION

After completion of a medical screening questionnaire and collection of baseline data, 4 glass cups were applied and pressurized over the lower erector spinae muscles.

OUTCOME MEASUREMENTS

Baseline data included demographic characteristics and the Oswestry Disability Questionnaire score. Pre- and postintervention data included perceived pain on a visual analog scale (VAS), lumbar spine range of motion, straight-leg raise test (SLR), and pain-pressure threshold (PPT) assessed with a digital force gauge. The data were analyzed by using a Wilcoxon signed-rank test and Spearman rho correlations.

RESULTS

Of the 17 patients who completed the study, there were significant post-treatment improvements in VAS scores (p=0.0001), SLR motion on the left (p=0.043), and lumbar flexion range of motion (p=0.016) and improvements in PPT at all 4 investigated points (p<0.007). Significant relationships were identified between the improvement in low back flexion with the improvement in PPT at bilateral lumbar paraspinal muscles at the L4 levels and at the left L2 level.

CONCLUSIONS

Chinese cupping may be a low-risk, therapeutic treatment for the prompt reduction of symptoms associated with subacute and chronic low back pain. Cupping may allow patients to progress to functional movement training in a timely manner by promptly reducing pain and muscle tenderness and improving range of motion.
