Abstract Abstract Background: Although, non-specific chronic low back pain (NSCLBP) has been associated with abnormal lumbosacral kinematics, little is known about the possible driving mechanisms of pain development overtime during prolonged sitting period. Therefore, the purpose of this study was to examine the differences in lumbosacral postures in adults with and without NSCLBP, and their role on pain development during a 1-hour of prolonged sitting task. Methods: Twenty NSCLBP subjects with motor control impairment (MCI) [10 classified as having flexion pattern (FP) disorder, and 10 with active extension pattern (AEP) disorder], and 10 healthy controls participated in the study. Subjects underwent a 1-hour sitting protocol on a standard office chair. Lumbosacral postures including: sacral tilt (ST), third lumbar vertebrae (L3) position, and relative lower lumbar angle (RLLA) were recorded using a two-dimensional inclinometer over the 1-hour period. Perceived back pain intensity was recorded using a numeric pain rating scale every 10 minutes throughout the sitting period. Results: All study groups presented with significantly distinctive lumbosacral kinematics at the lowest level of pain (the beginning of the sitting period) (p<0.05), as well as at the highest level of pain (the end of the sitting period) (p£0.05). The MCI subgroups showed a significant deterioration in lumbosacral kinematics and pain levels overtime (p<0.01). The directions of deterioration in lumbosacral kinematics over the 1-hour sitting period occurred in the direction of the motor control impairment (kyphosis for FP subgroup or lordosis for the AEP subgroup). Both MCI subgroups reported a similarly significant increase in pain through mid-sitting (p<0.001). However, after mid-sitting, the AEP subgroup displayed a significantly reversed decrease in the lordotic postures (p=0.001) which was accompanied by much less increase in pain level compared to the FP subgroup. Conclusion : The present study’s findings suggest that MCI subgroups presented with distinctive underlying maladaptive postural patterns. However, the significant increase in pain over the 1-hour sitting might not be only attributed to the inherent maladaptive postures, also it may be related to the directional deterioration in lumbosacral postures overtime.

Objective: Refractory chronic low back pain (CLBP) often leads to treatment with long-term opioids. Our goal was to describe the pharmaco-toxicological profile of opioid-treated CLBP patients and identify potential areas for care optimization.Design: Cross-sectional analysis.Setting: Outpatient primary care.Participants: CLBP patients prescribed ≥ 30 mg/d of morphine-equivalent dose (MED) for ≥3 months.Outcome Measures: Self-reported clinical, medication (verified) and substance use, and urine drug testing (UDT) data were collected.Results: Participants (N = 35) were 51.8 ± 9.7 years old, 80 percent female with CLBP for 14.2 ± 10.1 years, treated with opioids for 7.9 ± 5.7 years, with severe disability (Oswestry Disability Index score: 66.7 ± 11.4), and average pain score of 5.6 ± 1.5 (0-10 rating scale). Participants reported using tobacco (N = 14), alcohol (N = 9) and illicit drugs or unprescribed medications (N = 10). On average, participants took 13.4 ± 6.8 daily medications, including 4.7 ± 1.8 pain-modulating and 4.7 ± 2.0 sedating medications. Among prescribed opioids, 57.1 percent were long-acting and 91.4 percent were short-acting, with a total of 144.5 ± 127.8 mg/d of MED. Sixteen participants were prescribed benzodiazepines and/or zolpidem/zaleplon. Fifteen participants had UDT positive for illicit drugs or unprescribed medications; in addition, eight tested positive for alcohol and 19 for cotinine. Compared to those with negative UDTs, those with positive UDTs (N = 15) received lower daily “total” and “extended release” opioid doses, and were more likely to test positive for cotinine (p < 0.05).Conclusions: Study findings corroborate existing evidence for high medication burden and high likelihood of substance misuse among opioid-treated CLBP patients. Further research is needed to help understand causality and ways to optimize care and clinical outcomes.

The identification of homogeneous subgroups of patients with chronic low back pain (CLBP), based on distinct patterns of motor control, could support the tailoring of therapy and improve the effectiveness of rehabilitation. The purpose of this review was (1) to assess if there are differences in motor variability between patients with CLBP and pain-free controls, as well as inter-individually among patients with CLBP, during the performance of functional tasks; and (2) to examine the relationship between motor variability and CLBP across time. A literature search was conducted on the electronic databases Pubmed, EMBASE, and Web of Science, including papers published any time up to September 2021. Two reviewers independently screened the search results, assessed the risk of bias, and extracted the data. Twenty-two cross-sectional and three longitudinal studies investigating motor variability during functional tasks were examined. There are differences in motor variability between patients with CLBP and pain-free controls during the performance of functional tasks, albeit with discrepant results between tasks and among studies. The longitudinal studies revealed the persistence of motor control changes following interventions, but the relationship between changes in motor variability and reduction in pain intensity was inconclusive. Based on the reviewed literature, no stratification of homogeneous subgroups into distinct patterns of motor variability in the CLBP population could be made. Studies diverged in methodologies and theoretical frameworks and in metrics used to assess and interpret motor variability. In the future, more large-sample studies, including longitudinal designs, are needed, with standardized metrics that quantify motor variability to fill the identified evidence gaps.

Abstract Chronic low back pain affects 50-80% of the population, while its consequences may impair the functioning of patients suffering from it, in many spheres of life . Hope is a factor which may influence coping with pain as well as cognitive reflection of pain experience. The aim of the study has been to check: 1) whether dependencies exist between hope-trait and hope-state and the perception of pain; 2) whether experiencing pain at the time of filling questionnaires matters for the assessment of the level of hope; 3) whether there is interaction between hope, the pain experienced at the moment of investigation, and memory of the intensity of previously experienced pain. 150 patients participated in the study, they all reported aggravation of the chronic low back pain syndrome. The study was a cross-sectional study, based on questionnaires. On the third day of treatment the subjects were given the following questionnaires: Trait Hope Scale, State Hope Scale, and Numerical Rating Scale of Pain to fill. Poor correlation was demonstrated to exist between hope-state and hope-pathways on the one hand, and the intensity of minimum pain level experienced during the first three days of treatment. It has been noted that the presence of pain at the time of filling questionnaires results in reducing the hope-state, but only in those persons, who had experienced severe pain previously. On the other hand, in case of patients who had experienced slight pain previously, the pain present when filling in the questionnaires is conducive to enhanced hope-state. The results of the study confirm the complex character of relations between hope and pain.

ObjectivesEvaluate the outcomes and explore experiences of patients undergoing a residential combined physical and psychological programme (CPPP) for chronic low back pain.DesignA longitudinal observational cohort design, with a parallel qualitative design using semistructured interviews.SettingResidential, multimodal rehabilitation.Participants136 adults (62 male/74 female) referred to the CPPP, 100 (44 male/56 female) of whom completed the programme, during the term of the study. Ten (2 male/8 female) participated in the qualitative evaluation.InterventionA 3-week residential CPPP.Outcome measuresPrimary outcome measures were the STarT Back screening tool score; pain intensity—11-point Numerical Rating Scale; function—Oswestry Disability Index (ODI); health status/quality of life—EQ-5D-5L EuroQol five-Dimension-five level; anxiety—Generalised Anxiety Disorder-7; depression—Patient Health Questionnaire-9. Secondary outcome measures were the Global Subjective Outcome Scale; National Health Service Friends and Family Test;.ResultsAt discharge, 6 and 12 months follow ups, there were improvements from baseline that were greater than minimum clinically important differences in each of the outcomes (with the sole exception of ODI at discharge). At 12 months, the majority of people considered themselves a lot better (57%) and were extremely likely (86%) to recommend the programme to a friend. The qualitative data showed praise for the residential nature of the intervention and the opportunities for interaction with peers and peer support. There were testimonies of improvements in understanding of pain and how to manage it better. Some participants said they had reduced, or stopped, medication they had been taking to manage their pain.ConclusionsParticipants improved, and maintained long term, beyond minimum clinically important differences on a wide range of outcomes. Participants reported an enhanced ability to self-manage their back pain and support for the residential setting.

Introduction. In this study we are aiming to evaluate the changes of serum serotonin and its association with pain in patients suffering from chronic low back pain before and after lumbar discectomy surgery. Patients and Methods. A prospective study was performed on the patients referring to the outpatient clinic in Besat hospital, Hamadan University of Medical Sciences, Hamadan, Iran, during 2016. A 2 mL fasting blood sample was collected from each patient at preoperative day 1 and postoperative day 14 and they were measured for level of serum serotonin. Besides, all patients were asked for severity of their low back pain in preoperative day 1 and postoperative day 14 and scored their pain from zero to ten using a Numerical Rating Scale. Results. Forty patients with the mean age of 47 ± 13 yrs/old (range 25–77) including 15 (37.5%) males were enrolled into the study. The overall mean score of preoperative pain was significantly decreased from 7.4 ± 2.18 (range 4–10) to the postoperative pain score 3.87 ± 2.92 (range 0–10) (P < .001). The overall levels of pre- and postoperative serum serotonin were 3.37 ± 1.27 (range 1.1–6.4) and 3.58 ± 1.32 (range .94–7.1) ng/mL, respectively, with no significant difference (P = .09). The levels of pre- and postoperative serum serotonin were significantly higher in males and patients older than 50 yrs/old compared to the females and patients younger than 50 yrs/old, respectively (P = .03 and .005, respectively). A significant inverse correlation between the postoperative levels of pain and serum serotonin was observed (r = -.36 and P = .02). Conclusion. A negative medium strength linear relationship may exist between the postoperative serum serotonin and low back pain.

BackgroundThe evidence that exercise intervention is effective for treatment of chronic low back pain comes from trials that are not placebo-controlled.ObjectiveThe purpose of this study was to investigate the efficacy of motor control exercise for people with chronic low back pain.DesignThis was a randomized, placebo-controlled trial.SettingThe study was conducted in an outpatient physical therapy department in Australia.PatientsThe participants were 154 patients with chronic low back pain of more than 12 weeks’ duration.InterventionTwelve sessions of motor control exercise (ie, exercises designed to improve function of specific muscles of the low back region and the control of posture and movement) or placebo (ie, detuned ultrasound therapy and detuned short-wave therapy) were conducted over 8 weeks.MeasurementsPrimary outcomes were pain intensity, activity (measured by the Patient-Specific Functional Scale), and patient's global impression of recovery measured at 2 months. Secondary outcomes were pain; activity (measured by the Patient-Specific Functional Scale); patient's global impression of recovery measured at 6 and 12 months; activity limitation (measured by the Roland-Morris Disability Questionnaire) at 2, 6, and 12 months; and risk of persistent or recurrent pain at 12 months.ResultsThe exercise intervention improved activity and patient's global impression of recovery but did not clearly reduce pain at 2 months. The mean effect of exercise on activity (measured by the Patient-Specific Functional Scale) was 1.1 points (95% confidence interval [CI]=0.3 to 1.8), the mean effect on global impression of recovery was 1.5 points (95% CI=0.4 to 2.5), and the mean effect on pain was 0.9 points (95% CI=−0.01 to 1.8), all measured on 11-point scales. Secondary outcomes also favored motor control exercise.LimitationClinicians could not be blinded to the intervention they provided.ConclusionsMotor control exercise produced short-term improvements in global impression of recovery and activity, but not pain, for people with chronic low back pain. Most of the effects observed in the short term were maintained at the 6- and 12-month follow-ups.

Background: Few studies have focused on depressive symptoms among patients with chronic low back pain in China. The aim of this cross-sectional study was to assess the prevalence and associated factors of depressive symptoms in patients with chronic low back pain.Methods: From May to August 2021, 1,172 patients with chronic low back pain were recruited in China. Depressive symptoms were assessed through the Patient Health Questionnaire. Associations of demographic characteristics, clinical characters and social-psychological factors with depressive symptoms were investigated among patients with chronic low back pain.Results: The prevalence of depressive symptoms was 25.00%. Logistic regression analysis found that duration of pain in 1-5 years (1-3 years: OR = 2.91, 95%CI: 1.65-5.14, 3-5 years: OR = 3.09, 95%CI: 1.55-6.15) and more severe pain (OR = 1.13, 95%CI: 1.10-1.17) were associated with higher risks of depressive symptoms. Better family function (good family function: OR = 0.25, 95%CI: 0.15-0.41, moderate family dysfunction: OR = 0.47, 95%CI: 0.29-0.77) and higher pain self-efficacy (OR = 0.94, 95%CI: 0.93-0.95) were associated with lower risks of depressive symptoms.Conclusion: Patients with chronic low back pain have a high prevalence of depressive symptoms in China. Duration of pain, pain severity, family function and pain self-efficacy were predictors of depressive symptoms among chronic low back pain patients in China. Early identification of the associated factors may be helpful for the timely management of depressive symptoms.
