Recurrent Low Back Pain

Study Design: Prospective, concurrent-cohort study. Objectives: To determine the effects of volitional preemptive abdominal contraction (VPAC) on trunk control during an asymmetric lift in patients with recurrent low back pain (rLBP) and compare with matched controls. Methods: Thirty-two rLBP patients and 37 healthy controls performed asymmetric lifting with and without VPAC. Trunk, pelvis, and hip biomechanical along with neuromuscular activity parameters were obtained using 3-dimensional motion capture and electromyography system. Hypotheses were tested using analysis of variance. Results: The VPAC resulted in significantly reduced muscle activity across all trunk extensor muscles in both groups (M ± SD, 6.4% ± 8.2% of maximum contraction; P ≤ .005), and reduced trunk side flexion (1.4° ± 5.1° smaller; P ≤ .005) and hip abduction (8.1° ± 21.1° smaller; P ≤ .003). rLBP patients exhibited reduced muscle activity in external oblique (12.3% ± 5.5% of maximum contraction; P ≤ .012), as well as decreased hip flexion (4.7°, P ≤ .008) and hip abduction (5.2°, P ≤ .001) at the final position of lifting in comparison with healthy controls. Conclusions: The results of this study defend the recommendation that the use of a VPAC increase spine stability during an asymmetrical loading task. Our results provide an indication that a VPAC strategy that is achieved during an asymmetric lifting decreases exposure for lumbar spine injury and instability. Spine care providers and ergonomists can use this information when designing neuromuscular control training programs, both for healthy individuals aimed at prevention of injury, as well as those with a history of rLBP, aimed at full functional recovery and protection from future injury.

Abstract Context: Isolated lumbar paraspinal muscle fatigue causes lower extremity and postural control deficits. Objective: To describe the change in body position during gait after fatiguing lumbar extension exercises in persons with recurrent episodes of low back pain compared with healthy controls. Design: Case-control study. Setting: Motion analysis laboratory. Patients or Other Participants: Twenty-five recreationally active participants with a history of recurrent episodes of low back pain, matched by sex, height, and mass with 25 healthy controls. Intervention(s): We measured 3-dimensional lower extremity and trunk kinematics before and after fatiguing isometric lumbar paraspinal exercise. Main Outcome Measure(s): Measurements were taken while participants jogged on a custom-built treadmill surrounded by a 10-camera motion analysis system. Results: Group-by-time interactions were observed for lumbar lordosis and trunk angles (P < .05). A reduced lumbar spine extension angle was noted, reflecting a loss of lordosis and an increase in trunk flexion angle, indicating increased forward trunk lean, in healthy controls after fatiguing lumbar extension exercise. In contrast, persons with a history of recurrent low back pain exhibited a slight increase in spine extension, indicating a slightly more lordotic position of the lumbar spine, and a decrease in trunk flexion angles after fatiguing exercise. Regardless of group, participants experienced, on average, greater peak hip extension after lumbar paraspinal fatigue. Conclusions: Small differences in response may represent a necessary adaptation used by persons with recurrent low back pain to preserve gait function by stabilizing the spine and preventing inappropriate trunk and lumbar spine positioning.

Abstract Background Low back pain (LBP) is one of the most common musculoskeletal disorders, causing significant personal and social burden. Current research is focused on the processes of the central nervous system (particularly the sensorimotor system) and body perception, with a view to developing new and more efficient ways to treat chronic low back pain (CLBP). Several clinical tests have been suggested that might have the ability to detect alterations in the sensorimotor system. These include back-photo assessment (BPA), two-point discrimination (TPD), and the movement control tests (MCT). The aim of this study was to determine whether the simple clinical tests of BPA, TPD or MCT are able to discriminate between nonspecific CLBP subjects with altered body perception and healthy controls. Methods A cross-sectional study was conducted. At one point in time, 30 subjects with CLBP and 30 healthy controls were investigated through using BPA, TPD and MCT on the lower back. Correlations among the main covariates and odds ratios for group differences were calculated. Results MCT showed an odds ratio for the presence of CLBP of 1.92, with a statistically significant p-value (0.049) and 95%CI. The TPD and BPA tests were unable to determine significant differences between the groups. Conclusions Of the three tests investigated, MCT was found to be the only suitable assessment to discriminate between nonspecific CLBP subjects and healthy controls. The MCT can be recommended as a simple clinical tool to detect alterations in the sensorimotor system of nonspecific CLBP subjects. This could facilitate the development of tailored management strategies for this challenging LBP subgroup. However, further research is necessary to elucidate the potential of all the tests to detect alterations in the sensorimotor system of CLBP subjects. Trial registration No trial registration was needed as the study contains no intervention. The study was approved by the Swiss Ethics Commission of Northwest and Central Switzerland (EKNZ) reference number 2015–243.

Background:Common low back pain (LBP) is a common health problem affecting 50 to 80% of working age adults. It is one of the common and costly health problems in Tunisia. Actually, the role of the immune response and inflammatory cytokines in the pathogenesis of chronic pain has been of growing interest.Objectives:The aim of this study was to assess whether pro and anti-inflammatory cytokines could be detected in serum in patients with LBP compared with healthy subjects and whether they could be related to pain severity and to clinical findings.Methods:It was a an analytical cross-sectional study including 50 patients with at least three months of LBP, in the department of rheumatology, orthopedics and immunology at the Military Hospital of Tunis between January 1st and March 31, 2020. All patients had a standardized clinical assessment.Levels of serum cytokines IL-6, IL-8, IL-1β and TNF- α, were measured using the chimiluminescence technique. Serum concentration of IL-10 was assayed by the enzyme-linked immunosorbent assay technique (ELISA). The normal levels of cytokines were determined in 50 healthy controls.Results:The mean age of the patients was 41.9 ± 8.4 years and the sex ratio was 4.5. LBP duration was 66.4 months. The mean lumbar visual analog scale (VAS) was 4.5 ± 1.9, and the root VAS was 2.6 ± 2.5. Neuropathic pain was found in 26% of patients. The average BMI was 27 ± 3.7 kg/m2. Only serum level of IL-8 was significantly higher in subjects with LBP compared to healthy controls (p <10-3). IL-1β was indetectable in both patients and controls. Positive correlations were found between IL-8 levels and anxiety/functional scores (r = 0.3; p = 0.02/ r = 0.3; p = 0.04). IL-6 was positively correlated with BMI, and negatively correlated with the Schober test. No correlations were found between serum levels of IL-6, IL-8, IL-10, TNF-α and pain intensity (VAS), neuropathic pain (DN4), fibromyalgia (FIRST), depression (HAD) and various radiological data.Conclusion:Interleukin-8 is a biomarker of common low back pain and correlate with anxiety and functional disability. These results suggest that IL-8 may be a therapeutic target to reduce chronic back pain and reduce the social and profession impact.Disclosure of Interests:None declared

Background: Physiotherapy students are prone to low back pain (LBP) due to studying and their active involvement in clinical treatment of patients. As a result of pathology, muscle activity is influenced, affecting optimal function of the spine. Method: Physiotherapy students enrolled for 2010 at the University of the Witwatersrand participated in a cross-sectional study. A questionnaire and physical assessment were completed. Results: The study revealed that the lifetime LBP prevalence was 36% among physiotherapy students. Associations with LBP were hours of practical exposure, posterior-anterior mobilisations on L4 (p=0.003) and L5 (p≤0.001) centrally and unilaterally, left lumbar multifidus (LM) cross-sectional area (p=0.02), right obliquus internusabdominis (OI) (p=0.02) and right transversus abdominis (TrA) thickness at rest (p=0.02), as well as the pull of the TrA during contraction on the left (p=0.03). Discussion: Hours of practical exposure may play a role in lumbar pathology. Due to pathology, muscle imbalances of LM, TrA and OI affect the stability of the spine which may lead to recurrences. Conclusion: Practical exposure as well as LM, TrA and OI muscle imbalances were associated with LBP in physiotherapy students. Awareness of the factors associated with LBP while studying at an undergraduate level may lead to better prevention of LBP.
