Impact of Multifidus Muscle Morphometry on the Clinical Evolution of Chronic Low Back Pain

Purpose: The multifidus muscle is an important extensor muscle of the lumbar spine. It plays a major role in the stability and realization of axial rotation movements of the thoraco-lumbar spine. Its atrophy by fatty degeneration would be at the origin of the occurrence of chronic low back pain which constitutes a public health problem in Senegal. Taking into account its anatomy is essential for the etiopathogenic analysis and the treatment of low back pain. The purpose of our work was to investigate the impact of multifidus muscle morphometry on the anatomy-clinical evolution of low back pain. Material and method: this was a prospective study over a period of 30 months from November 2019 to May 2022. It involved 100 patients seen in the neurology department of Fann Hospital for chronic low back pain and who had already had a scanner falling within the criteria for low back pain. We used 3D Slicer, SPSS 20, Excel 2016 software to model and analyze the morphometric data of the multifidus muscle after physiotherapy and control lumbar scans. Results: The sex ratio was 2.23. The average age of the patients was 45 ± 7 years. On the initial CT scan, according to the Hadar classification, we noted a predominance of grade 2 with 56% in L5/S1, followed by grade 1 with 32% and grade 3 with 14%. In L4/L5, the majority of patients, 67%, had grade 1. A conflicting circumferential disc bulge with the roots predominating in L5/S1 was present in 94% of men (p-value = 0.02). Before physiotherapy, the average volume of the multifidus was 193 mm3 ± 39, after physiotherapy it was 203 mm3 ± 42 with a progression rate of 5.2%. Clinically, severe type pain had regressed from 86% before physiotherapy to 0% after physiotherapy (p-value = 0.03). Conclusion: Taking into account the morphometry of the multifidus is an essential element in the management of chronic low back pain.

Risk Factors of Low Back Pain among the Chinese Occupational Population:A Case-control Study

Objective To explore the risk factors of low back pain among the Chinese occupational population in several major industries.Methods A total of 7200 subjects(3600 cases and 3600 controls) were randomly sampled from a cross-sectional study,and they were investigated for individual and occupational factors of low back pain.The potential risk factors were first selected by using chi-square tests.Secondly,collinearity diagnosis proceeded by using the Kendall's rank correlation.Finally,binary logistic regression model was used for multi-factor analysis.Results Collinearity diagnosis showed that there was a severe collinearity problem among the potential risk factors of low back pain.Logistic regression model included 20 variables with statistical significance.Bending neck forward or holding neck in a forward posture for long periods(OR=1.408) was the most important risk factor inducing low back pain in this study,followed by bending heavily with the trunk(OR=1.402),carrying out identical work almost for the whole day(OR=1.340).Additionally,sufficient normal break was a protective factor of low back pain.Conclusion Low back pain among the Chinese occupational population was associated with body height,occupation,work organization,physical work,working posture,and others.All these risk factors could be regarded as the indicators of low back pain,and some relevant preventive measures should be taken to reduce low back pain risk.

Balance Control Comparison between Subjects with and without Non-specific Low Back Pain

Objective:To compare the balance ability between normal people and non-specific low back pain(nsLBP) patients and explore the relationship between balance ability and muscle function in nsLBP patients.Method:Ten nsLBP patients as nsLBP group and 10 age and gender-matched healthy control subjects as control group were investigated.Posturography on balance platform and surface electromyography(sEMG) were performed to assess all the subjects' function of equilibrium and muscle activities of erector spinea(ES),multifidus(MF),abdominal external oblique(EO),hamstring(HS) and maximal gluteus(MG) bilaterally.Result:The nsLBP subjects had greater sway on anterior-posterior direction(Y-speed and Y-extension,P=0.05) on feet-together posture and bigger main axis(P=0.023) on nature standing with eyes closed when compared with controls.The iEMG ratios of right MG in nature standing(eyes closed)/nature standing(eyes open) and feet-together(eyes open)/nature standing(eyes open) in control group were significant higher than that in nsLBP group(P=0.03 and P=0.013).Conclusion:Balance evaluation combined with sEMG measurement on trank and lower limb muscles provided some quantitative information about functional deficits such as postural control and muscle activities in nsLBP patients.This relationship should be emphasized in prevention and rehabilitation of nsLBP.

Analgesic effects of balanced acupuncture versus body acupuncture in low-back and leg pain patients with lumbar disc herniation, as assessed by resting-state functional magnetic resonance imaging

Balanced acupuncture, a single-acupoint balance therapy, regulates the balance of the cerebral center, and is characterized by exerting quick effects and a short treatment course. A total of 20 low-back and leg pain patients with lumbar disc herniation were treated with balanced acupuncture or body acupuncture. Central mechanisms of varied acupunctures were compared using resting-state functional MRI. Patients from both groups received functional MRI before and after acupuncture. Functional connectivity in brain regions that were strongly associated with the bilateral amygdala was analyzed utilizing AFNI software. Visual analogue scale scores were greater in the balanced acupuncture group compared with the body acupuncture group. Function of the endogenous pain regulation network was enhanced in patients in the balanced acupuncture group, but was not changed in the body acupuncture group. This result indicates that the analgesic effects of body acupuncture do not work through the central nervous system. These data suggest that balanced acupuncture exerts analgesic effects on low-back and leg pain patients with lumbar disc herniation by regulating the function of the endogenous pain regulation network.

Resting-state connectivity in the default mode network and insula during experimental low back pain

Functional magnetic resonance imaging studies have shown that the insular cortex has a significant role in pain identification and information integration, while the default mode network is associated with cognitive and memory-related aspects of pain perception. However, changes in the functional connectivity between the default mode network and insula during pain remain unclear. This study used 3.0 T functional magnetic resonance imaging scans in 12 healthy subjects aged 24.8 ± 3.3 years to compare the differences in the functional activity and connectivity of the insula and default mode network between the baseline and pain condition induced by intramuscular injection of hypertonic saline. Compared with the baseline, the insula was more functionally connected with the medial prefrontal and lateral temporal cortices, whereas there was lower connectivity with the posterior cingulate cortex, precuneus and inferior parietal lobule in the pain condition. In addition, compared with baseline, the anterior cingulate cortex exhibited greater connectivity with the posterior insula, but lower connectivity with the anterior insula, during the pain condition. These data indicate that experimental low back pain led to dysfunction in the connectivity between the insula and default mode network resulting from an impairment of the regions of the brain related to cognition and emotion, suggesting the importance of the interaction between these regions in pain processing.

Do people with low back pain walk differently? A systematic review and meta-analysis

Background:The biomechanics of the trunk and lower limbs during walking and running gait are frequently assessed in individuals with low back pain(LBP).Despite substantial research,it is still unclear whether consistent and generalizable changes in walking or running gait occur in association with LBP.The purpose of this systematic review was to identify whether there are differences in biomechanics during walking and running gait in individuals with acute and persistent LBP compared with back-healthy controls.Methods:A search was conducted in PubMed,CINAHL,SPORTDiscus,and PsycINFO in June 2019 and was repeated in December 2020.Studies were included if they reported biomechanical characteristics of individuals with and without LBP during steady-state or perturbed walking and running.Biomechanical data included spatiotemporal,kinematic,kinetic,and electromyography variables.The reporting quality and potential for bias of each study was assessed.Data were pooled where possible to compare the standardized mean differences(SMD)between back pain and back-healthy control groups.Results:Ninety-seven studies were included and reviewed.Two studies investigated acute pain and the rest investigated persistent pain.Nine studies investigated running gait.Of the studies,20%had high reporting quality/low risk of bias.In comparison with back-healthy controls,individuals with persistent LBP walked slower(SMD=-0.59,95%confidence interval(95%CI):-0.77 to-0.42)and with shorter stride length(SMD=-0.38,95%CI:-0.60 to-0.16).There were no differences in the amplitude of motion in the thoracic or lumbar spine,pelvis,or hips in individuals with LBP.During walking,coordination of motion between the thorax and the lumbar spine/pelvis was significantly more in-phase in the persistent LBP groups(SMD=-0.60,95%CI:-0.90 to-0.30),and individuals with persistent LBP exhibited greater amplitude of activation in the paraspinal muscles(SMD=0.52,95%CI:0.23-0.80).There were no consistent differences in running biomechanics between groups.Conclusion:There is moderate-to-strong evidence that individuals with persistent LBP demonstrate differences in walking gait compared to back-healthy controls.

Efficacy and safety of thermobalancing therapy with Dr Allen’s Device for chronic low back pain:A randomised controlled trial

BACKGROUND Lumbar disc herniation and non-specific low back pain are common conditions that seriously affect patients’health-related quality of life(HRQoL).Although empirical evidence has demonstrated that novel Thermobalancing therapy and Dr Allen’s Device can relieve chronic low back pain,there have been no randomised controlled trials for these indications.AIM To evaluate the efficacy of Dr Allen’s Device in lumbar disc herniation(LDH)and non-specific low back pain(NSLBP).METHODS A randomised clinical trial was conducted investigating 55 patients with chronic low back pain due to LDH(n=28)or NSLBP(n=27),out of which 15 were randomly assigned to the control group and 40 were assigned to the treatment group.The intervention was treatment with Dr Allen’s Device for 3 mo.Changes in HRQoL were assessed using the Numerical Pain Rating Scale and the Japanese Orthopedic Association Back Pain Questionnaire.RESULTS Thermobalancing therapy with Dr Allen’s Device showed a significant reduction in pain in the treatment group(P<0.001),with no recorded adverse effects.Both pain assessment scales showed a significant improvement in patients’perception of pain indicating improvement in HRQoL.CONCLUSION The out-of-hospital use of Thermobalancing therapy with Dr Allen’s Device for Low Back Treatment relieves chronic low back pain significantly and without adverse effects,improves the level of activity and HRQoL among patients with LDH and NSLBP.This study demonstrates the importance of this safe first-line therapy that can be used for effective at-home management of chronic low back pain.

McKenzie Therapists Adhere More to Evidence-Based Guidelines and Have a More Biopsychosocial Perspective on the Management of Patients with Low Back Pain than General Physical Therapists in Japan

Design: Cross-sectional. Objective: Aim 1 was to preliminarily explore the contributions of the following factors to adherence to LBP practice guidelines using regression modeling: 1) the credential qualification of Mechanical Diagnosis and Therapy (MDT);2) balance of biomedical and behavioral (i.e. biopsychosocial) oriented approach for low back pain (LBP);3) demographics;4) academic degree and 5) the attitude towards updating information for evidence-based clinical practice. Aim 2 was to investigate whether therapists credentialed in MDT (Cred.MDT) were more behavioral oriented and less biomedical oriented than general physical therapists. Summary of Background Data: LBP practice guidelines are not adhered to by every physical therapist. MDT is a behavioral modification approach. Thus, it was hypothesized that the Cred.MDT therapist was more behavioral oriented and more adherent to LBP practice guidelines compared with general physical therapists. Methods: One-hundred-twenty Cred.MDT therapists and 2000 general physical therapists in Japan were contacted. For regression modeling, the dependent variable was adherent to guidelines using a questionnaire with a vignette. Independent variables included balance of biomedical and behavioral perspectives for LBP using the Pain Attitudes and Beliefs Scale for Physiotherapist (PABS-PT), demographics, academic degree and the attitude towards updatinginformation for evidence-based clinical practice. The ratio of the two mean scores of the biomedical and behavioral subscales in the PABS-PT was compared between the Cred.MDT therapist group and the general physical therapists group. Results: Data of 46 general physical therapists and 44 Cred.MDT therapists were available. The Cred.MDT therapist group was significantly (P < 0.05) more behavioral oriented and more adherent to LBP practice guidelines compared with the general physical therapist group. The regression indicated significance of the two predictors of adherence to guidelines, Cred.MDT (β = 0.58, P < 0.001) and academic degree (β = 0.19, P = 0.03). Conclusions: Cred.MDT therapists are more guideline-consistent and have a more biopsychosocial treatment orientation than general physical therapists in Japan.

Efficacy of Low Dose Naltrexone on Pain Reduction in Chronic Pain Syndromes: A Meta Analysis

Chronic pain is a multifaceted debilitating experience often associated with significant physical and emotional burden. Low dose naltrexone (LDN) has gained attention in recent years for its potential utility in the management of fibromyalgia, irritable bowel syndrome, multiple sclerosis, and painful diabetic neuropathy. LDN’s analgesic effects have been associated with its ability to increase the production of endorphins while reducing the production of tumor necrosis factor-alpha, interleukin-6, reactive oxygen species and nitric oxide. This meta-analysis aims to systematically review and synthesize the available evidence on efficacy of LDN as an analgesic in pain syndromes, with a focus on chronic (neuro) inflammatory diseases. The goal is to provide clinicians with a more comprehensive estimate of the effectiveness of LDN as a non-opioid option for managing chronic pain and guide future research in the area. Thirteen randomized control trials, published from 1990 to 2022, were selected for the analysis that satisfied inclusion criteria. The overall effects in these studies were calculated using the standardized mean difference (SMD) between the LDN and placebo groups. We found an overall SMD of -10.77 (95% CI: -13.96 to -7.58) with a p-value of 0.002. This indicated that the LDN group experienced a statistically significant reduction in pain compared to placebo. This meta-analysis provides evidence for the potential efficacy of low dose naltrexone in reducing pain and enhancing analgesia in various pain syndromes. LDN may be a useful treatment option for patients suffering from chronic pain, particularly with fibromyalgia, multiple sclerosis, or diabetic neuropathy. However, further research is needed to confirm the efficacy and safety of low dose naltrexone for chronic pain conditions, especially with larger sample sizes, standardized dosing regimens and treatment durations.

Prevalence and influencing factors of low back pain among nurses in China:a systematic review and meta-analysis

Background:Low back pain(LBP)is one of the most common occupational injuries that nurses experience in their daily work,which ultimately causes disability or difficulty in performing heavy physical activity.There is scarce information that presents a direct figure about the prevalence of LBP in Chinese nurses.Objective:To systematically review and analyze the prevalence and influencing factors of LBP among nurses in China.Methods:Related literature extracted from PubMed,Web of Science,Scopus,China National Knowledge Infrastructure databases were selected and reviewed based on the PRISMA guideline.Random effects models were used for data analysis,where heterogeneity was tested through I2.Egger’s test was used to analyze the literature publication bias.Results:The combined data indicated that the prevalence of LBP among nurses in China was 78%[95%confidence interval(CI)=0.72–0.83].The prevalence of LBP among nurses in China has declined in the past decade.Nurses presented a high risk of LBP in terms of female(OR=2.38,95%CI=1.23–3.44,P<0.0001),married(OR=2.79,95%CI=1.57–3.86,P<0.0001),24≤BMI<28(OR=2.03,95%CI=1.18–3.08,P<0.0001),and working for more than ten>10 years(OR=2.54,95%CI=2.03–3.32,P<0.0001).Conclusions:There is a high prevalence of LBP among nurses in China.Interventions that include healthy dietary habits and physical activity mainly focusing on female married nurses who are working for at least 10 years should be implemented.Furthermore,nurses ought to apply ergonomic principles for personal protection at the workplace.

Slacklining as therapy to address non-specific low back pain in the presence of multifidus arthrogenic muscle inhibition

Low back pain(LBP)represents the most prevalent,problematic and painful of musculoskeletal conditions that affects both the individual and society with health and economic concerns.LBP is a heterogeneous condition with multiple diagnoses and causes.In the absence of consensus definitions,partly because of terminology inconsistency,it is further referred to as non-specific LBP(NSLBP).In NSLBP patients,the lumbar multifidus(MF),a key stabilizing muscle,has a depleted role due to recognized myocellular lipid infiltration and wasting,with the potential primary cause hypothesized as arthrogenic muscle inhibition(AMI).This link between AMI and NSLBP continues to gain increasing recognition.To date there is no‘gold standard’or consensus treatment to alleviate symptoms and disability due to NSLBP,though the advocated interventions are numerous,with marked variations in costs and levels of supportive evidence.However,there is consensus that NSLBP management be cost-effective,self-administered,educational,exercise-based,and use multi-modal and multi-disciplinary approaches.An adjuvant therapy fulfilling these consensus criteria is‘slacklining’,within an overall rehabilitation program.Slacklining,the neuromechanical action of balance retention on a tightened band,induces strategic indirect-involuntary therapeutic muscle activation exercise incorporating spinal motor control.Though several models have been proposed,understanding slacklining’s neuro-motor mechanism of action remains incomplete.Slacklining has demonstrated clinical effects to overcome AMI in peripheral joints,particularly the knee,and is reported in clinical case-studies as showing promising results in reducing NSLBP related to MF deficiency induced through AMI(MF-AMI).Therefore,this paper aims to:rationalize why and how adjuvant,slacklining therapeutic exercise may positively affect patients with NSLBP,due to MF-AMI induced depletion of spinal stabilization;considers current understandings and interventions for NSLBP,including the contributing role of MF-AMI;and details the reasons why slacklining could be considered as a potential adjuvant intervention for NSLBP through its indirect-involuntary action.This action is hypothesized to occur through an over-ride or inhibition of central down-regulatory induced muscle insufficiency,present due to AMI.This subsequently allows neuroplasticity,normal neuro-motor sequencing and muscle re-activation,which facilitates innate advantageous spinal stabilization.This in-turn addresses and reduces NSLBP,its concurrent symptoms and functional disability.This process is hypothesized to occur through four neuro-physiological processing pathways:finite neural delay;movement-control phenotypes;inhibition of action and the innate primordial imperative;and accentuated corticospinal drive.Further research is recommended to investigate these hypotheses and the effect of slacklining as an adjuvant therapy in cohort and control studies of NSLBP populations.

髋-脊柱综合征患者全髋置换后腰痛与脊柱-骨盆矢状位参数变化的关系

背景:很多研究表明髋-脊柱综合征患者行全髋关节置换后腰痛会改善,然而关于置换后腰痛改善与脊柱-骨盆矢状位参数变化的关系研究较少,此次研究旨在揭示二者之间的联系。目的:探讨髋-脊柱综合征患者行全髋关节置换后腰痛改善与脊柱-骨盆矢状位参数变化的关系。方法:回顾性分析2019年1月至2022年1月徐州医科大学附属医院收治的93例行初次全髋关节置换治疗且合并腰痛的终末期髋关节疾病患者的临床和影像学资料。置换前及置换后1年随访时于腰椎侧位X射线片上测量脊柱-骨盆矢状位参数:骨盆入射角、骨盆倾斜角、骶骨倾斜角、腰椎前凸角、骨盆入射角和腰椎前凸角的差值,记录患者置换前及置换后1年目测类比评分、Oswestry功能障碍指数及髋关节Harris评分。根据患者置换后1年目测类比评分变化是否达到腰痛治疗最小临床重要性差异分为2组,其中腰痛未改善组45例,腰痛改善组48例,对比两组患者置换前一般资料、置换前后脊柱-骨盆矢状位参数差值、Oswestry功能障碍指数及髋关节Harris评分。结果与结论:①两组患者在年龄、性别、手术侧别、体质量指数、病因等方面相比差异均无显著性意义(P>0.05),具有可比性;②两组置换前目测类比评分无明显差异(P>0.05),置换后1年腰痛改善组目测类比评分低于腰痛未改善组(P<0.01);③置换后1年,腰痛未改善组的腰椎前凸角较置换前明显减小,而腰痛改善组的腰椎前凸角较置换前减小较少(P<0.01);同时,腰痛未改善组的骨盆入射角和腰椎前凸角的差值不匹配较术前增大,而腰痛改善组骨盆入射角和腰椎前凸角的差值不匹配较术前减小,两组之间差异有显著性意义(P<0.01),两组患者其余脊柱-骨盆矢状位参数变化比较无明显差异(P>0.05);④两组置换前腰椎Oswestry功能障碍指数以及髋关节Harris评分比较无明显差异(P>0.05);置换后1年腰痛改善组Oswestry功能障碍指数低于腰痛未改善组,且髋关节Harris评分高于腰痛未改善组(P<0.05);⑤提示髋-脊柱综合征患者行全髋关节置换后腰痛改善与脊柱骨盆矢状位参数变化有关,表现出腰椎前凸角减小以及骨盆入射角和腰椎前凸角的差值不匹配减小,且术后腰痛改善患者的功能评分更好,说明全髋关节置换改善了脊柱排列及脊柱骨盆矢状面平衡,对于髋-脊柱综合征患者,在腰椎疾病出现之前行全髋关节置换会对腰椎产生有利的影响。

[Objectives]This paper aimed to investigate the effect of Tuina combined with sling exercise therapy(SET)and psoas&abdominal training on serum 5-hydroxytryptamine(5-HT)andβ-endorphin(β-EP)levels in patients with nonspecific low back pain(NLBP).[Methods]Total 46 patients with NLBP who visited the Tuina Department of the First Affiliated Hospital of Hainan Medical University from August 2019 to May 2020 were randomly and evenly divided into control group and treatment group.On the basis of Tuina therapy,the patients in the control group and treatment group were treated with psoas&abdominal training and SET,respectively.After the treatment,the serum 5-HT andβ-EP levels of the patients were detected.[Results]The serum 5-HT andβ-EP levels in the treatment group were significantly improved compared with the control group(P<0.05).[Conclusions]The nerve&muscle reconstruction techniques of Tuina combined with SET or psoas&abdominal training can improve serum 5-HT andβ-EP levels in patients with NLBP.

Pregnancy-Related Low Back Pain Relief after Maximum Static Flexibility Program

Background: Pregnancy-related low back pain (LBP) impacts pregnancy. Flexibilizing facilitates movements providing posture correction and pain relief. Objective: To analyze effects of a maximum static flexibility program on pregnancy’s LBP. Methods: Clinical prospective randomized controlled trial. Setting: Brazilian Governmental Health Program’s prenatal care. Participants: 40 volunteer of pregnant women, gestational age between 20 and 31 weeks, with/without LBP randomly assigned to experimental group (EG) or control group (CG): EG n = 20 (E1 with LBP and E2 without LBP) and CG n = 20 (C1 with LBP and C2 without LBP). Interventions: EG intervention was sessions of static flexion. CG received conventional medical treatment. Pain intensity was measured by visual analog scale (VAS) of pain. Chi-square, Wilcoxon and the Kruskal-Wallis statistical tests were adopted. Results: Concerning percent variation (Δ%) E1 presented 56.4% reduction of LBP while E2, C1, C2 increased LBP by 2.9%, 0.1%, 0.5% respectively. Wilcoxon test outcome comparing pre- and post-test of experimental and control groups on pain intensity levels presented significant E1 p < 0.05. Kruskal-Wallis test comparing post-test C1 with E1 with E2 and C2 presented p < 0.05 (C1 post vs. E1 post: p = 0.006;C1 post vs. E2 post: p < 0.0001;C1 post vs. C2 post: p = 0.002), showing significant effect of the experimental treatment. Conclusion: Gains on LBP for EG show that the static flexibilizing exercises reduce and prevent pregnancy-related LBP.

Novel approach of ultrasound-guided lateral recess block for a patient with lateral recess stenosis: A case report

BACKGROUND Ultrasound guide technology,which can provide real-time visualization of the needle tip and tissues and avoid many adverse events,is widely used in mini-mally invasive therapy.However,the studies on ultrasound-guided Lateral recess block(LRB)are limited,this is probably because there is no recognized standard method for ultrasound scanning.This study aimed to evaluate the effect of ultrasound-guided LRB in patients with lateral recess stenosis(LRS).CASE SUMMARY A 65-year-old patient complained of low back pain accompanied occasionally by pain and numbness in the left lower limb.Physical examination showed ten-derness on the spinous process and paraspinal muscles from L1 to S1,extensor hallucis longus and tibialis anterior weakness(muscle strength:4-),and a positive straight leg raising test in the left lower limb(60°).Magnetic resonance imaging showed L4–L5 disc degeneration with left LRS and nerve root entrapment.Subsequently,the patient was diagnosed with LRS.This patient was treated with a novel ultrasound-guided LRB approach.The patient’s symptoms significantly improved without any complications at 1 wk postoperatively and at the 3-month follow-up.CONCLUSION This is the first report on the LRS treatment with ultrasound-guided LRB from the contralateral spinous process along the inner side of the articular process by out-plane technique.Further studies are expected to investigate the efficacy and safety of ultrasound-guided LRB for patients with LRS.

Thermal Therapy in Patients Suffering from Non-Specific Chronic Low Back Pain—A Systematic Review

Thermal therapy is frequently used as an adjunct to treatment in patients suffering from chronic low back pain. It is also an inherent part of patients’ self-administered pain treatment. This review aims to update the evidence for thermal therapy treatments in non-specific chronic low back pain patients and to rate the methodological quality of the corresponding clinical trials. Previous studies have reported contradictory evidence for the effectiveness of thermal therapy. An electronic search on MEDLINE (PubMed), PEDro, CENTRAL and CINHAL databases was conducted between May 2016 and February 2018. Clinical trials comparing local thermal therapy to conservative or no treatment were assessed for eligibility. Pain, physical function and global health were defined as outcome parameters. A total of n = 9 studies met the inclusion criteria. All of them applied an electrophysical agent as the thermal treatment: continuous ultrasound (n = 6), short-wave diathermy (n = 2), microwave diathermy (n = 1). Out of the n = 6 studies on ultrasound treatment, n = 2 reported significant within and between-group results for pain reduction after 4 to 6 weeks of treatment. Both short-wave diathermy studies demonstrated significant between-group results for pain reduction after 3 weeks of treatment. Contradictory results for all other observed outcome parameters were reported regardless of the intervention. Moreover, significant within-group results for the control groups questioned the effectiveness of the intervention treatments. Therefore, the effect of thermal therapy, (electrophysical agents), is not superior to any control treatment except for ultrasound treatment on short-term pain reduction.

Anxiety and Depression Disorders in Chronic Non-Specific Low Back Pain in Lomé(Togo)

Chronic non-specific low back pain has an important psychological impact. Objectives: To determine the prevalence of anxiety and depressive disorders (ADD) and factors associated to their apparition in patients suffering from chronic non-specific low back pain in rheumatological consultation in Lomé. Patients and Methods: It was a cross-sectional study, conducted from October 1st, 2015 to 31st March 2016. This study focused on all patients suffering from common chronic low back pain without psychiatric history in the Rheumatology Ward at the Sylvanus Olympio’s Teaching Hospital of Lomé and who have given their consent. The psychological evaluation was carried out through Hamilton scale. The processing, the statistical treatment and analysis of our data have been carried out using Epiinfo software, version 7.1.5. The investigation was approved by the local Ethics Committee. Results: 48 (39 women and 09 men) out of 123 patients with chronic lower back pain presented anxiety and depressive disorders (ADD) accounting for a prevalence rate of 39%. Their average age was 50.3 years old. The most frequent ADD was: psychic anxiety (58.6%), depressive mood (51.3%), difficulties to feel asleep (47.9%) and disturbed or agitated sleep (43.1%). Factors associated with the anxiety and depressive disorders in common chronic low back pain were: female gender (p = 0.02), dependent children (p = 0.02), occupation (reseller (p = 0.002), liberal profession (p = 0.009), monthly financial income (p = 0.002), surroundings family (0.009), medical history (p = 0.0002) and pain’s intensity > 7 (p = 0.04). Conclusion: This study shows the high frequency of anxiety and depressive disorders in common chronic low back pain and their influence by socio-economic and demographic factors.
