Association of demographics, lumbar active range of motion and disability in chronic low back: a baseline data analysis of a randomized controlled trial from Pakistan.

BACKGROUND: The disability and significant economic costs accredited to Low back pain (LBP) are likely to rise which is an essential problem in low and middle-income countries like Pakistan. The associated factors of LBP are age, sex, and race including physical activity, high spinal load, lifting, bending, and twisting occupations. The literature highlighted there is substantial differences in associated factors of LBP within available studies in developing countries. The objective is to investigate the association of demographic factors and lumbar range of motion with disability in patients with chronic low back. METHODS: A baseline data analysis was performed as an analytical cross-sectional study among 150 patients with chronic low back in a randomized controlled trial with a duration from March 2020 and January 2021. After recording demographics, Modified-Modified Schober's test was used to measure lumbar flexion and extension and Oswestry disability index for disability. After the descriptive analysis the continuous variables, age and pain were analyzed with Spearman's correlation. Variables that were significant in bivariate analysis were then fitted in a multivariable linear regression. The Kruskal-Wallis test was used to analyze variations of disability in gender, marital status, work status, education level, and duration of pain. The p-value of 0.05 was significant. RESULTS: The results showed a significant correlation between age and pain in sitting (rh=-0.189, p = 0.021 and rh = 0.788, p < 0.001) with the disability but no significant effects of age and pain in sitting (B=-0.124, p = 0.212 and B = 1.128, p = 0.082) on disability were found. The decrease in lumbar flexion and extension was found to increase disability (B=-6.018 and - 4.032 respectively with p < 0.001). Female gender (x2(1) = 15.477, p = < 0.001) and unmarried marital status (x2(1) = 4.539, p = 0.033) had more disability than male gender and married marital status, respectively. There was a significance between groups of the duration of pain regarding disability (x2 (2) = 70.905, p < 0.001). Age, education level, and work status showed no significance (p > 0.05). CONCLUSIONS: The female gender and unmarried marital status are associated with functional disability. Decreased lumbar range of motion accompanies more disability, while age, education level, and work status do not effect on disability.

Prescription characteristics of Xue-Fu-Zhu-Yu-Tang in pain management: a population-based study using the National Health Insurance Research Database in Taiwan.

Objective: To explore the prevalence and distinctive features of Xue-Fu-Zhu-Yu-Tang (XFZYT) prescriptions by analyzing the National Health Insurance Research Database (NHIRD) to identify the specific medical problems for which XFZYT is prescribed. Methods: This nationwide, population-based, cross-sectional study included 109,073 XFZYT users and 532,848 XFZYT non-users among Chinese herbal product (CHP) users in NHIRD. Chi-squared tests were used to analyze disparities between the XFZYT user and XFZYT non-user cohorts, and the mean age was evaluated using the Wilcoxon rank-sum test. Logistic regression was used to compute the odds ratios (ORs) and 95% confidence intervals (95% CIs). Results: XFZYT was frequently used to treat pain. The top five conditions for which the Taiwanese traditional Chinese medicine (TCM) practitioners would prescribe XFZYT were chest pain; headache; myalgia and myositis; lumbago; and neuralgia, neuritis, and radiculitis. Conclusion: This study represents an inaugural comprehensive survey conducted on the utilization of XFZYT prescriptions among patients with diverse diseases. XFZYT is mostly used to treat pain conditions in Taiwan. Combined with the combination use of other CHPs, XFZYT is used to treat symptoms of the chest and respiratory system, soft tissue conditions, menstruation disorders, and joint and back discomfort. These results suggest that further clinical trials are warranted to verify the effects of XFZYT in pain management.

[Clinical and radiographic factors associated with the severity of paraspinal fatty infiltration in patients with degenerative low back disease]. / Factores clínicos y radiográficos asociados a la severidad de infiltración grasa paraespinal en pacientes con enfermedad lumbar degenerativa.

INTRODUCTION: Degenerative lumbar disease (DLE) is a spectrum of pathological changes from disc degeneration, herniated disc, spondylolisthesis and lumbar canal stenosis. The pain associated with it is multifactorial. Muscle cramps are among the most frequent causes. The relationship between muscle degeneration and DLE has already been studied in the past in multiple studies, highlighting the one carried out by Kjaer & cols. OBJECTIVE: to determine the prevalence and severity of fatty degeneration in mutifidus spinae, and to study its relationship with clinical and radiographic factors. MATERIAL AND METHODS: observational and analytical study. Patients diagnosed with: herniated disc, lumbar canal stenosis or degenerative scoliosis were included. They were classified according to the Kjaer scale for paraspinal fatty infiltration in one of three groups. Clinical variables were analyzed: age, smoking, obesity, the presence of axial pain, temporality of pain, severity expressed with a visual analog scale (VAS); and radiographic: number of diseased segments, involved segments, diagnostic imaging and the presence of spondylolisthesis. RESULTS: 56 patients with an average age of 52.5 years (16 to 80) with a predominance of females with 62.5% were included. The diagnoses were nonspecific low back pain (1.8%), herniated disc (42.9%), narrow lumbar duct (46.4%) and lumbar duct with degenerative scoliosis deformity (8.9%). The distribution among the three groups described by Kjaer was as follows: 44.6% were classified with a fat infiltration score of 2. In groups 1 and 0, 39.3% and 16.1% were classified respectively. The variables significantly related to greater fat infiltration were: age > 60 years, diagnoses of lumbar canal stenosis and herniated disc; obesity, spondylolisthesis < 2 vertebral segments involved. Axial pain and VAS > 8 points were not related to greater muscle degeneration. CONCLUSIONS: fatty infiltration is present in all patients with some of the forms of DLE. Most patients > 60 years of age with advanced degenerative processes have a greater severity of infiltration. Other related variables are: obesity, spondylolisthesis and disease of < 2 vertebral segments. There is no relationship between a higher percentage of fatty infiltration and axial pain or higher VAS scores.

INTRODUCCIÓN: la enfermedad lumbar degenerativa (ELD) es un espectro de cambios patológicos desde la degeneración discal, la hernia discal, la espondilolistesis y el conducto lumbar estrecho. El dolor que se le asocia es multifactorial. Los espasmos musculares son de las causas más frecuentes. La relación que guarda la degeneración muscular y la ELD ya ha sido estudiada en múltiples trabajos, destacando el realizado por Kjaer y colaboradores. OBJETIVO: determinar la prevalencia y severidad de la degeneración grasa en el mutifidus spinae, y estudiar su relación con variables clínicas y radiográficas. MATERIAL Y MÉTODOS: estudio observacional y analítico. Se incluyeron pacientes diagnosticados con: hernia discal, conducto lumbar estrecho o escoliosis degenerativa. Se clasificaron de acuerdo con escala de Kjaer para infiltración grasa paraespinal en alguno de tres grupos. Se analizaron variables clínicas: edad, tabaquismo, obesidad, presencia de dolor tipo axial, temporalidad del dolor, severidad del dolor expresada con escala visual análoga (EVA); y radiográficas: número de segmento enfermos, segmentos involucrados, diagnóstico por imagen y presencia de espondilolistesis. RESULTADOS: se incluyeron 56 pacientes con edad promedio de 52.5 años (rango 16 a 80) con predominio del sexo femenino (62.5%). Los diagnósticos fueron lumbalgia inespecífica (1.8%), hernia discal (42.9%), conducto lumbar estrecho (46.4%) y conducto lumbar con deformidad en escoliosis degenerativa (8.9%). La distribución entre los tres grupos descritos por Kjaer fue la siguiente: 44.6% fueron clasificados con un puntaje de infiltración grasa de 2. En los grupos 1 y 0, se clasificaron 39.3 y 16.1%, respectivamente. Las variables relacionadas con mayor infiltración grasa fueron: edad > 60 años, diagnósticos de conducto lumbar estrecho y hernia discal; obesidad, espondilolistesis < 2 segmentos vertebrales involucrados. El dolor mecánico y EVA > 8 puntos no se relacionaron con mayor degeneración muscular. CONCLUSIONES: la infiltración grasa está presente en todos los pacientes con alguna de las formas de ELD. La mayoría de los pacientes > 60 años con procesos degenerativos avanzados tienen mayor severidad de infiltración. Otras variables relacionadas son: obesidad, espondilolistesis y enfermedad < 2 segmentos vertebrales. No hay relación entre mayor porcentaje de infiltración grasa y dolor axial o puntajes más altos de dolor.

Usefulness of Stanch Belt Plus in Postoperative Management after Endovascular Neurosurgery.

Objective: We verified the usefulness of patient management using a balloon-pressurized belt (Stanch Belt Plus) to prevent puncture site hematomas, which can occur at a specific rate even with hemostatic devices after endovascular neurosurgery. Methods: A total of 113 patients who underwent endovascular surgery with a femoral puncture from April 2019 to September 2020 were divided into two groups: 31 cases using a traditional compression belt and 82 cases using a newly introduced balloon-pressurized belt during this period. The clinical data were analyzed retrospectively. The chi-square test and Mann-Whitney U test were used to test for significant differences. Results: There were no significant differences in treatment procedures or frequency of hemostatic device use, but the balloon-pressurized belt group had a significantly lower incidence of hematomas (2.4% vs 12.9%, p <0.05) and a significantly lower incidence of moderate or higher lumbago (22.0% vs 41.9%, p <0.05). The incidence of epidermal detachment tended to be low; however, no significant difference was observed (3.7% vs. 12.9%, n.s.). Conclusion: Patient management with the newly introduced balloon-pressurized belt may decrease the occurrence of groin hematoma and lumbago among complications after endovascular neurosurgery.

What are the benefits of cultivating self-compassion in adults with low back pain? A systematic review.

Introduction: Low back pain is one of the most prevalent public health problems in the world, generating psychosocial impacts on quality of life and a high demand for medical care. Self-compassion may be beneficial for low back pain control, however, studies in the area are scarce. Therefore, this systematic review aimed to investigate the benefits of self-compassion-related interventions on low back pain and mental health in adults. Methods: The review protocol was registered in PROSPERO and the method was performed according to the PRISMA guidelines. Searches were conducted using the keywords "self-compassion" and "low back pain" in Portuguese, English, and Spanish in the following databases: PubMed, LILACS, SciELO, PePSIC, PsycInfo, Embase, Scopus, Web of Science, and Cochrane. Additional searches were also conducted through the references of the included studies. Results: Thirty-three articles were identified and analyzed by two independent reviewers using Rayyan. Four of these studies were included. RoB 2 was used to assess the risk of bias of each study. The main findings suggest that self-compassion-related interventions demonstrate benefits in the treatment of low back pain, as well as reduction in pain intensity, psychological stress, and improvement of pain acceptance. Discussion: However, these positive data must be analyzed carefully, as only two studies presented a low risk of bias. Despite growing interest in this field, more research self-compassion-related interventions for low back pain are suggested, since biopsychosocial aspects associated with low back pain can impact the outcome of treatment.

Tension Distension Sign (Acevedo's Sign) for the Diagnosis of Lumbar Facet Syndrome: Technical Note.

The treatment of low back pain has evolved from an understanding of its pathophysiology, biomechanics, and therapy. The events that characterize the degenerative cascade of modifications that produce pain are well described. Facet joints are early affected when there is a loss of intervertebral disc height and may present biomechanical overload that translates into pain. Clinical diagnosis of lumbar facet syndrome is not straightforward because there are no specific features other than pain triggered by hyperextension + forced rotation of the lumbar spine in a standing position to suspect it. This implies that its diagnostic confirmation depends on bone scintigraphy and selective anesthetic blockade of the dorsal and medial branches of the joint. In this technical note, we present a new clinical sign (Tension Distension Signo sign/Acevedo's sign) described since 2004.

Low back pain, ultrasonographic muscle thickness measurements and biopsychosocial factors at different trimesters of pregnancy.

BACKGROUND: Pregnancy-related low back pain is a multifactorial problem and its assosiation with pain intensity and biopsycosocial factors can not be fully explained. This study aimed to determine the psychosocial as well as biological/physical risk factors associated with self-reported low back pain (LBP) intensity during different trimesters of pregnancy. METHODS: This cross-sectional study comprised 107 pregnant women. An introductory information form for physical and medical characteristics, Visual Analog Scale (VAS) for low back pain intensity and Oswestry Disability Index (ODI) for degree of loss of functionality, Short Form-36 (SF-36) for quality of life and Pregnancy Physical Activity Questionnaire (PPAQ) for physical activity were applied. Abdominal muscle thicknesses and diastasis recti were measured by ultrasonography. Univariate regression was used to analyse associations between each plausible independent variable and low back pain intensity. RESULTS: Mean LBP intensity during 1st, 2nd ve 3rd trimesters were 26.8 ± 20.9, 27.3 ± 19.8, 21.6 ± 20.1 mm, respectively. ODI scores were associated with LBP intensity, explaining 11%, 13% and 26% of LBP severity during the 1st, 2nd ve 3rd trimesters, respectively. Other biological/physical variables like age, body mass index, muscle thickness and diastasis recti were not associated with pain intensity. SF-36 emotional role limitation (coef = -0.03, R2 = 0.20, p = 0.01) in the 3rd trimester and SF-36 pain score in the 1st (coef = -0.04, R2 = 0.12, p = 0.02) and 3rd (coef = -0.05, R2 = 0.26, p = 0.004) trimesters and PPAQ-sedentary was associated during the 2nd trimester (coef = 0.17, R2 = 0.17, p = 0.02) with pain intensity. CONCLUSION: ODI scores were associated with LBP intensity in all three trimesters, with SF-36 pain domain in the 1st and 3rd trimesters, with SF-36 emotional role limitation only in the 3rd trimester and with sedentary activity level only in the 2nd trimester. Increased pain intensity was surprisingly associated with a small number of biopsychosocial factors in all the trimesters. There is need for further large-sample studies.

DCNAS-Net: deformation convolution and neural architecture search detection network for bone marrow oedema.

BACKGROUND: Lumbago is a global disease that affects more than 500 million people worldwide. Bone marrow oedema is one of the main causes of the condition and clinical diagnosis is mainly made by radiologists manually reviewing MRI images to determine whether oedema is present. However, the number of patients with Lumbago has risen dramatically in recent years, which has brought a huge workload to radiologists. In order to improve the efficiency of diagnosis, this paper is devoted to developing and evaluating a neural network for detecting bone marrow edema in MRI images. RELATED WORK: Inspired by the development of deep learning and image processing techniques, we design a deep learning detection algorithm specifically for the detection of bone marrow oedema from lumbar MRI images. We introduce deformable convolution, feature pyramid networks and neural architecture search modules, and redesign the existing neural networks. We explain in detail the construction of the network and illustrate the setting of the network hyperparameters. RESULTS AND DISCUSSION: The detection accuracy of our algorithm is excellent. And its accuracy of detecting bone marrow oedema reached up to 90.6[Formula: see text], an improvement of 5.7[Formula: see text] compared to the original. The recall of our neural network is 95.1[Formula: see text], and the F1-measure also reaches 92.8[Formula: see text]. And our algorithm is fast in detecting it, taking only 0.144 s per image. CONCLUSION: Extensive experiments have demonstrated that deformable convolution and aggregated feature pyramid structures are conducive for the detection of bone marrow oedema. Our algorithm has better detection accuracy and good detection speed compared to other algorithms.

Nonopioid pharmacological management of acute low back pain: A level I of evidence systematic review.

Acute low back pain (LBP) imposes a significant socioeconomical burden as it is the condition that, worldwide, cause the most disability. Nonetheless, the literature regarding the best pharmacological management of acute LBP is limited, and the indications available in the literature are conflicting. This work investigates whether the pharmacological management of acute LBP can effectively reduce pain and disability, and aims to identify which drugs show the highest efficacy. This systematic review was conducted according to the 2020 PRISMA statement. In September 2022, PubMed, Scopus, and Web of Science were accessed. All the randomized controlled trials investigating the efficacy of myorelaxants, nonsteroidal anti-inflammatory drugs (NSAIDs), and paracetamol for acute LPB were accessed. Only studies that investigated the lumbar spine were included. Only studies reporting on patients with acute LBP with symptom duration of less than 12 weeks were included. Only patients older than 18 years and with nonspecific low back pain were included. Studies that investigated the use of opioids in acute LBP were not considered. Data from 18 studies and 3478 patients were available. Myorelaxants and NSAIDs were effective in reducing pain and disability in acute LBP at approximately one week. The combination of NSAIDs and paracetamol was associated with a greater improvement than the use of NSAIDs alone, but paracetamol alone did not induce any significant improvement. Placebo was not effective in reducing pain. Clinical Significance: Myorelaxants, NSAIDs, and NSAIDs with paracetamol could reduce pain and disability in patients with acute LBP.

Association of Low Back Pain with Shift Work: A Meta-Analysis.

Shift work (SW) is the main working schedule worldwide, and it may cause sleep disorders, breast cancer, and cardiovascular disease. Low back pain (LBP) is a common problem in the workplace; however, the association between LBP and SW remains unclear. Therefore, we conducted a meta-analysis to determine the association between SW and LBP. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, Embase, and Web of Science databases using a set of associated keywords were queried. The inclusion criteria were as follows: (1) adult employees hired by a company or organization; (2) SW exposure; and (3) the outcome of LBP according to examination or assessment. A total of 40 studies were included that met the inclusion criteria for the meta-analysis. SW was significantly associated with LBP (odds ratio [OR]: 1.31, 95% confidence interval [CI]: 1.18−1.47, p < 0.00001). Furthermore, it was observed that LBP was significantly associated with night shift (NS) (OR: 1.49, 95% CI: 1.24−1.82, p < 0.0001) but not with rotating shift (RS) (OR: 0.96, 95% CI: 0.76−1.22, p = 0.49). Moreover, LBP was significantly associated with SW in health care workers (HCWs) (OR: 1.40, 95% CI: 1.20−1.63, p < 0.0001) but not in non-HCWs (OR: 1.19, 95% CI: 0.94−1.50, p = 0.14). SW was significantly associated with LBP. Furthermore, the subgroup analysis showed that NS, but not RS, was associated with LBP. Compared with SW in non-HCWs, SW in HCWs was significantly associated with LBP.

A retrospective study on the pathologies in patients with coccydynia-lumbosacralgia and their treatment.

BACKGROUND: The aim of this study was to arrange the treatment according to the etiology following the differential diagnosis in patients who had presented to the Orthopedics and Traumatology and General Surgery outpatient departments, and to emphasize the post-treatment success. METHOD: The charts of 156 patients who had presented to the Orthopedics and Traumatology, General Surgery Departments of the Kafkas University Faculty of Medicine between July 2012 and June 2021 were retrospectively reviewed after permission was obtained from the ethics committee in this study. The demographic findings and Visual Analogue Scale (VAS) results for those with a symptom of pain as detected during the physical examination were recorded from the patient charts. RESULTS: A total of 156 patients who had presented with traumatic and non-traumatic conditions to the Orthopedics Clinic complaining of pain, burning, sensitivity, discharge and hyperemia at the coccyx region were included in the study. The reason for the lumbosacralgia was found to be traumatic as in heavy lifting or working physically difficult jobs in 62 of the 95 patients (65.26%) who presented with lumbosacralgia and pain referred to the coccyx. The mean VAS was 7.37 before treatment and 2.32 following conservative treatment. There was a history of falling on the coccyx region in 8 of the 14 patients with traumatic isolated coccydynia. The pre-treatment mean VAS was 8.64 in the patients with a diagnosis of coccydynia while the post-treatment mean VAS was 0 in 8 patients with full recovery, 4.33 in 3 patients with partial recovery, and 9.66 in 3 patients with no recovery. The pre-treatment mean VAS was 7.58 in the 29 patients with thrombosed hemorrhoids, decreasing to 0 after treatment. The pre-treatment mean VAS was 4.16 in the 18 patients with a pilonidal sinus, again decreasing to 0 after treatment. CONCLUSION: Possible underlying etiological factors should be taken into account when making a diagnosis in patients with coccydynia and the treatment should be determined in a multidisciplinary manner.

Analysis of misdiagnosed cases of neck, shoulder, waist and leg pain caused by bone metastases and early warning measures / 中国基层医药

Objective:To investigate the cause of misdiagnosis of neck, shoulder, waist, and leg pain caused by bone metastases and to improve the outpatient diagnosis rate.Methods:Five misdiagnosed cases of bone metastases who were admitted to the Traditional Chinese Medicine Department of Orthopedics and Traumatology, School of Traditional Chinese Medicine, Southern Medical University from January 2019 to July 2020 were included in this study. Their clinical manifestations, diagnosis results (outside hospital diagnosis and outpatient diagnosis), and imaging manifestations were retrospectively analyzed.Results:Five cases of bone metastases were misdiagnosed to have cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain. Accelerated red blood cell sedimentation rate and increased C-reactive protein level were found in all five cases. Bone metastases were confirmed by X-ray, CT, and MRI examination results. All of them had warning signs for bone metastasis: age > 50 years, history of a tumor, unexplained weight loss, general malaise, neck, shoulder, waist, and leg pain without an obvious cause, sudden worsening of pain, night pain, resting pain, pain on direct palpation, no obvious improvements in these symptoms after symptomatic treatment for 1 month, disease development not conforming to the general law of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, increases in red blood cell sedimentation rate, C-reactive protein, and alkaline phosphatase levels, which are not consistent with the symptoms of cervical spondylosis, lumbar disc herniation, femoral head necrosis, femoral shaft fracture, and ankle sprain, and slight external force leading to fractures.Conclusion:Further tests and imaging examinations should be performed according to warning signs. Clinical schemes of malignant bone tumors suitable for general practitioners can easily, economically, and effectively identify malignant bone tumors.

Effects of administration of α2 adrenergic receptor agonist into psoas major muscle on inflammatory pain induced by injection of complete Freund's adjuvant in rats.

α2 adrenergic agonists are widely used in clinical anesthesia and ICU sedation owing to their effective sedative and analgesic effects. Lumbago and leg pain is the most common clinical pain disease. Studies have reported that lumbago and leg pain is associated with dysregulation of paravertebral muscles, especially psoas major muscles. In the present study, a unilateral lower extremity chronic inflammation and pain model was established by subcutaneous administration of low-dose complete Fredrin's adjuvant (CFA) into the posterior paw of rats. α2 adrenalin receptor agonist was then injected into the psoas major muscle. Behavioral tests were conducted for 21 days. Psoas major muscle tissue was harvested for evaluation of biochemical indexes related to pain. The effect of α2 adrenergic receptor agonist injected into psoas major muscle on chronic inflammatory pain of lower extremities in rats was explored. The results showed that injection of α2 adrenergic receptor agonist into the psoas major muscle relieved CFA-induced mechanical hyperalgesia. Administration of α2 adrenergic receptor antagonist yohimbine reversed the analgesic effect of α2 adrenergic receptor agonists. Administration of dexmedetomidine into psoas major muscle downregulated the levels of norepinephrine, interleukin-6 and tumor necrosis factor-α in tissues. The findings of the present study show that administration of α2 adrenoceptor agonists into the psoas major muscle relieves chronic inflammatory pain induced by CFA. Local injection of dexmedetomidine also exerted anti-inflammatory and anti-sympathetic effect by activating α2-adrenoceptor in the psoas major muscle.

Comparison of an Iranian Traditional Massage (Fateh Method) with Physiotherapy and Acupuncture for Patients with Chronic Low Back Pain: a Randomized Controlled Trial.

Background: Low back pain (LBP) is currently a major reason for disability worldwide. Therapeutic massage is one of the most popular non-pharmacological methods for managing chronic LBP (CLBP), and the Fateh method is a massage technique based on Iranian Traditional Medicine. Objectives: The current study aimed to compare the effects of Fateh massage with those of acupuncture and physiotherapy on relieving pain and disability in CLBP. Methods: Eighty-four patients with CLBP were categorized into groups that received Fateh massage, acupuncture, or physiotherapy. Each group included 28 randomly assigned patients who completed 10 sessions of therapy. Visual analogue scale (VAS) scores and Roland-Morris disability scores were evaluated at baseline, after intervention, and four weeks later. The findings were analyzed with SPSS software. Results: The baseline VAS and Roland-Morris scores of the three study groups did not indicate significant differences (p > 0.05). All three groups showed significant pre-post improvements in both scores (p < 0.05). At the end of the treatment sessions, the three groups showed no significant difference in the reductions in pain intensity and disability score (p > 0.05). Improvements in disability and pain between the first and third time points were significant in all three groups (p < 0.05 for each group). In addition, the results of massage, physiotherapy, and acupuncture groups were not significantly different (p > 0.05). No adverse events occurred in the patients. Conclusion: The effects of Fateh massage were comparable to those of acupuncture and physiotherapy in reducing pain and disability in patients with CLBP.

Anatomical changes in lumbosacral vertebrae and their correlation with facet joint-derived low back pain in patients with hip osteoarthritis after total hip arthroplasty: a cohort study.

Background: Little is known about the anatomical changes in lumbosacral vertebrae and their correlation with facet joint-derived low back pain in patients with hip osteoarthritis (HOA) after total hip arthroplasty. Methods: Seventy-four HOA patients with low back pain who underwent initial total hip arthroplasty were included. Their Harris Hip Score (HHS), Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) and anatomical parameters were analyzed. Paired t-tests were used to compare the various index scores before and after surgery, and independent sample t-tests were used for the between-group comparisons. Results: The HHS and ODI significantly changed at 3 and 6 months postoperatively [HHS: preoperative (43.56±4.34) vs. 3 months (80.34±5.23) vs. 6 months (84.37±4.78); ODI: preoperative (36.26±5.34) vs. 3 months (26.44±3.23) vs. 6 months (19.34±3.27); P<0.001]. At the first 3 months after surgery, the VAS low back pain score decreased from 5.24±1.21 to 2.89±1.03 (P<0.001), and the VAS hip pain score decreased from 7.45±1.32 to 2.34±1.12 (P<0.001). There was also a statistically significant difference between the preoperative and 1-month postoperative anatomical indices: lumbar lordosis (LL) increased significantly after surgery [preoperative (43.46°±13.89°) vs. 1 month (48.27°±14.42°), P=0.001], while slip angle (SA) decreased significantly [preoperative (89.20°±5.03°) vs. 1 month (84.45°±4.89°), P=0.010]. Sacral slope (SS) and radial abduction angle (RAA) showed significant postoperative changes compared with preoperative assessments; after surgery, SS increased significantly [preoperative (31.33°±8.23°) vs. 1 month (37.65°±8.19°), P=0.006), while RAA decreased significantly [preoperative (42.32°±8.12°) vs. 1 month (35.45°±7.67°), P=0.021]. Moreover, the increase of LL was both significantly correlated with the decrease of the VAS low back pain (P=0.009) and the VAS hip pain score (P=0.038). Conclusions: Total hip arthroplasty was associated with the anatomical changes in lumbosacral vertebrae.

Motion sickness decreases low back function and changes gene expression in military aircrew.

BACKGROUND: Motion sickness and low back disorders are prevalent and debilitating conditions that affect the health, performance, and operational effectiveness of military aircrews. This study explored the effects of a motion sickness stimulus on biomechanical and genetic factors that could potentially be involved in the causal pathways for both disorders. METHODS: Subjects recruited from a military population were exposed to either a mild (n = 12) or aggressive (n = 16) motion sickness stimulus in a Neuro-Otologic Test Center. The independent variable of interest was the motion sickness stimulus exposure (before vs. after), though differences between mild and aggressive stimuli were also assessed. Dependent measures for the study included motion sickness exposure duration, biomechanical variables (postural stability, gait function, low back function, lumbar spine loading), and gene expression. FINDINGS: Seven of twelve subjects experiencing the mild motion sickness stimulus endured the full 30 min in the NOTC, whereas subjects lasted an average of 13.2 (SD 5.0) minutes in the NOTC with the aggressive motion sickness stimulus. Mild motion sickness exposure led to a significant decrease in the postural stability measure of sway area, though the aggressive motion sickness exposure led to a statistically significant increase in sway area. Both stimuli led to decreases in low back function, though the decrease was only statistically significant for the mild protocol. Both stimuli also led to significant changes in gene expression. INTERPRETATION: Motion sickness may alter standing balance, decrease low back function, and lead to changes in the expression of genes with roles in osteogenesis, myogenesis, development of brain lymphatics, inflammation, neuropathic pain, and more. These results may provide preliminary evidence for a link between motion sickness and low back disorders.

MRI of Acute Low Back Pain: About an Uncommon Pitfall.

Posteriorly migrated disc extrusion may mimic tumoral masses on MRI with contrast; still, this diagnosis must be evoked in patients presenting acute low back pain with a posterior epidural mass. We describe a case of epidural posterior migration of an inflammatory lumbar disc herniation in a young patient with acute lumbosciatica. MRI showed an intracanalar mass with intense global enhancement, which is an uncommon feature of this rare condition.

[Therapeutic injections and manual medicine in low-back pain : Bimodal synergies between evidence and empiricism]. / Therapeutische Injektion und Manuelle Medizin beim tiefen Rückenschmerz : Bimodale Synergien zwischen Evidenz und Empirie.

BACKGROUND: Oriented towards the therapy planning and management of rheumatic patients, and based on the differentiated therapeutic principles of manual medicine (MM) with knowledge on evidence of therapeutic local infiltration techniques (TLI), the author pleads for the establishment of a structured, mechanism-based therapy concept in the sense of "treat to target" (T2T) for patients with (chronic) degenerative low-back pain (LBP) in outpatient pain therapy care. DIAGNOSTICS: This requires a consistent (primary) diagnosis with pain analysis under the premise that LBP is always specific if it is structurally and functionally conditioned. A broad bio-psycho-social anamnesis and structure-based clinical diagnosis (imaging) with functional differentiation according to MM principles and, if necessary, interventional blocks, should result in the expression of a three-level diagnosis as a prerequisite for a mechanism-based, hierarchic step therapy in LBP. In this article, this is presented in a pragmatic, case-oriented manner, with the implementation of techniques and evidence of TLI and MM.

[Spinal manipulation therapy in low back pain : Why? When? Where? How?] / Manualmedizinische Interventionen bei Kreuzschmerzen : Warum? Wann? Wo? Wie?

BACKGROUND: Manipulation and mobilisation for low back pain are presented in an evidence-based manner with regard to mechanisms of action, indications, efficacy, cost-effectiveness ratio, user criteria and adverse effects. Terms such as non-specific or specific are replaced by the introduction of "entities" related to possible different low back pain forms. EFFICACY: MM is effective for acute and chronic low back pain in terms of pain relief, recovery of function and relapse prevention. It is equally effective but less risky compared to other recommended therapies. MM can be used alone in acute cases and not only in the case of chronic low back pain where it is always and necessarily part of a multimodal therapy programme, especially in combination with activating measures. The users of MM should exclusively be physician specialists trained according to the criteria of the German Medical Association (Bundesärztekammer) with an additional competence in manual medicine or appropriately trained certified therapists. The application of MM follows all rules of Good Clinical Practice. ADVERSE EFFECTS: Significant adverse effects of MM for low back pain are reported in the international literature with a frequency of 1 per 50,000 to 1 per 3.7 million applications, i.e. MM for low back pain is practically risk-free and safe if performed according to the rules of the European Training Requirements of the UEMS.
