Efficacy and Safety of Spinal Collagen Mesotherapy in Patients with Chronic Low Back Pain in a Three-Month Follow-Up—Retrospective Study

Background: Low back pain syndrome is associated with muscular and myofascial pain and is linked with muscle overstrain or a lack of regular physical activity as well as a habitual bad posture, which cause the overload of perispinal soft tissues. One of the forms of therapy of LBP is the mesotherapy of the spine, which consists of multi-point micro-injections of drugs or medicine mixtures, which include preparations of collagen type I. The aim of the study was to assess the efficacy and safety of mesotherapy with collagen type I. Methods: A retrospective analysis of the results of the treatment of patients with chronic low back pain syndrome using mesotherapy was performed. A total of 130 patients (83 women and 47 men; mean age: 51 ± 14 years) were divided into two groups: group I (n = 65), treated with collagen type I, and group II (n = 65), treated with lignocaine 1%. Mesotherapy was performed weekly over five weeks. Patients were assessed using the following scales: the VAS, Laitinen Scale, and Revised Oswestry Low Back Pain Disability Scale before the start of the treatment, after five treatments, and at the three-month follow-up visit. Results: A statistically significant improvement was observed after the use of spinal mesotherapy both with collagen type I and lignocaine, with the collagen treatment having better results at the three-month follow-up visit. No adverse effects were observed after the procedures. Conclusions: Spinal mesotherapy using collagen type I and lignocaine seems to be an effective method in the treatment of chronic LBP. Collagen mesotherapy gives better results in the long term. Mesotherapy is a safe form of therapy.

Clinical analysis of qualitative and quantitative pain characteristics in patients with acute and chronic vertebrogenic lumbosacral pain syndromes

Diverse approaches exist for diagnosing and treating patients afflicted with acute and chronic low back pain syndromes (LBP), thereby necessitating a comprehensive evaluation of the pain syndrome and a meticulous analysis of the neuropathic component to enhance our scholarly comprehension of the distinct differences in pain progression among these individuals. A total of 125 individuals (56 females and 69 males) diagnosed with vertebral lumbar pain syndromes (LBP), aged between 20 and 68 years (42.8 ± 11.1 years), underwent comprehensive evaluation. Stratification into two distinct groups was based on the duration of the pain syndrome: an acute pain group (pain lasting up to 3 months) and a chronic pain group (pain persisting beyond 3 months). Pain assessment, administered upon hospitalization, involved utilizing of well-established tools such as the Visual Analogue Scale (VAS), DN4 Questionnaire, and McGill Pain Questionnaire. The initial pain intensity, measured by VAS upon admission, was recorded as 7.15 ± 1.17 in the acute pain group and 6.08 ± 0.96 in the chronic pain group. Analysis of responses to the DN4 questionnaire revealed that patients with acute pain syndrome obtained an average score of 2.26 ± 1.01, whereas those in the chronic pain group scored 4.53 ± 1.02. The presence of a neuropathic component was identified in 38 % of patients with acute pain and 56 % of patients with chronic pain. Correlational analyses indicated a weak positive correlation (r = 0.12, p < 0.05) between VAS scores and the assessment of neuropathic pain using the DN4 questionnaire in the acute pain group. However, the chronic pain group observed a moderate positive correlation (r = 0.41, p < 0.001). Patients experiencing chronic LBP expressed their pain sensations in a more emotionally descriptive manner. Notably, the chronic pain group exhibited a statistically significant elevation in the number of selected descriptors according to the Index of Chosen Descriptors (ICD) on the sensory scale, as well as an increased Pain Rank Index (PRI) on both sensory and affective scales, compared to the acute pain group. To summarize, individuals with chronic LBP exhibit a more prevalence of the neuropathic component. Moreover, patients in the chronic pain group demonstrated higher scores indicative of sensory and psychosocial aspects of pain. Key words: acute pain, chronic pain, neuropathic component of pain, verbal descriptors, McGill Pain Questionnaire

Chronic overlapping pain conditions and long-term opioid treatment.

One in 5 people in the United States lives with chronic pain. Many patients with chronic pain experience a subset of specific co-occurring pain conditions that may share a common pain mechanism and that have been designated as chronic overlapping pain conditions (COPCs). Little is known about chronic opioid prescribing patterns among patients with COPCs in primary care settings, especially among socioeconomically vulnerable patients. This study aims to evaluate opioid prescribing among patients with COPCs in US community health centers and to identify individual COPCs and their combinations that are associated with long-term opioid treatment (LOT). Retrospective cohort study. We conducted analyses of more than 1 million patients 18 years and older based on electronic health record data from 449 US community health centers across 17 states between January 1, 2009, and December 31, 2018. Logistic regression models were used to assess the relationship between COPCs and LOT. Individuals with COPCs were prescribed LOT 4 times more often than individuals without a COPC (16.9% vs 4.0%). The presence of chronic low back pain, migraine headache, fibromyalgia, or irritable bowel syndrome combined with any of the other COPCs increased the odds of LOT prescribing compared with the presence of a single COPC. Although LOT prescribing has declined over time, it remains relatively high among patients with certain COPCs and for those with multiple COPCs. These study findings suggest target populations for future interventions to manage chronic pain among socioeconomically vulnerable patients.

Motor corticospinal excitability abnormalities differ between distinct chronic low back pain syndromes

ObjectivesIt is not known whether cortical plastic changes reported in low-back pain (LBP) are present in all etiologies of LBP. Here we report on the assessment of patients with three LBP conditions: non-specific-LBP (ns-LBP), failed back surgery syndrome (FBSS), and sciatica (Sc). MethodsPatients underwent a standardized assessment of clinical pain, conditioned pain modulation (CPM), and measures of motor evoked potential (MEPs)-based motor corticospinal excitability (CE) by transcranial magnetic stimulation, including short interval intracortical inhibition (SICI), and intracortical facilitation (ICF). Comparisons were also made with normative data from sex- and age-matched healthy volunteers. Results60 patients (42 women, 55.1±9.1 years old) with LBP were included (20 in each group). Pain intensity was higher in patients with neuropathic pain [FBSS (6.8±1.3), and Sc (6.4±1.4)] than in those with ns-LBP (4.7±1.0, P<0.001). The same was shown for pain interference (5.9±2.0, 5.9±1.8, 3.2±1.9, P<0.001), disability (16.4±3.3, 16.3±4.3, 10.4±4.3, P<0.001), and catastrophism (31.1±12.3, 33.0±10.4, 17.4±10.7, P<0.001) scores for FBSS, Sc, and ns-LBP groups, respectively. Patients with neuropathic pain (FBSS, Sc) had lower CPM (-14.8±1.9, -14.1±16.7, respectively) compared to ns-LBP (-25.4±16.6; P<0.02). 80.0% of the FBSS group had defective ICF compared to the other two groups (52.5% for ns-LBP, P=0.025 and 52.5% for Sc, P=0.046). MEPs (140%-rest motor threshold) were low in 50.0% of patients in the FBSS group compared to 20.0% of ns-LBP (P=0.018) and 15.0% of Sc (P=0.001) groups. Higher MEPs were correlated with mood scores (r=0.489), and with lower neuropathic pain symptom scores(r=-0.415) in FBSS. ConclusionsDifferent types of LBP were associated with different clinical, CPM and CE profiles, which were not uniquely related to the presence of neuropathic pain. These results highlight the need to further characterize patients with LBP in psychophysics and cortical neurophysiology studies.

Restless legs syndrome in patients with chronic low back pain.

Based on studies showing that both chronic low back pain (LBP) and restless legs syndrome (RLS) have similar pathophysiological mechanisms, we aimed to investigate the prevalence of RLS in patients with chronic LBP and to define which demographic and clinical features are prominent in those with LBP accompanied by RLS. One hundred and two eligible, volunteer participants with chronic LBP were enrolled in this study. Visual analog scale (VAS), the Oswestry Disability Index (ODI), Pittsburgh Sleep Quality Index, Beck Depression Inventory, and Short Form-36 scales were applied to the patients. All patients were evaluated face-to-face for RLS using the International RLS study group diagnostic criteria. Most of our patients were women (52%). The mean age was 40.96±13.34years and the mean disease duration was 46.16±41.98months. RLS was detected in 36 (35.3%) of the patients with LBP. It was found that the female gender was more dominant in patients with RLS and the difference was statistically significant (p < 0.001). The amount of coffee intake was significantly higher in patients with RLS compared to those without RLS (p = 0.001). The disease duration for LBP was significantly higher in the patients with RLS (p = 0.003). VAS score, ODI score, PUKI score, and Beck depression score were significantly higher in the RLS group (p value were 0.048, 0.040, 0.007, and 0.043, respectively). In the evaluation of quality of life, all parameters except role emotional limitations and mental health were found to be significantly worse in the RLS group.

Spinal Cord Stimulation in Chronic Low Back Pain Syndrome: Mechanisms of Modulation, Technical Features and Clinical Application.

Chronic low-back pain (CLBP) is a common disease with several negative consequences on the quality of life, work and activity ability and increased costs to the health-care system. When pharmacological, psychological, physical and occupational therapies or surgery fail to reduce CLBP, patients may be a candidate for Spinal Cord Stimulation (SCS). SCS consists of the transcutaneous or surgical implantation of different types of electrodes in the epidural space; electrodes are then connected to an Implanted Pulse Generator (IPG) that generates stimulating currents. Through spinal and supraspinal mechanisms based on the “gate control theory for pain transmission”, SCS reduces symptoms of CLBP in the almost totality of well-selected patients and its effect lasts up to eight years in around 75% of patients. However, the evidence in favor of SCS still remains weak, mainly due to poor trial methodology and design. This narrative review is mainly addressed to those professionals that may encounter patients with CLBP failing conventional treatments. For this reason, we report the mechanisms of pain relief during SCS, the technical features and some clinical considerations about the application of SCS in patients with CLBP.

Individual Patterns and Temporal Trajectories of Changes in Fear and Pain during Exposure In Vivo: A Multiple Single-Case Experimental Design in Patients with Chronic Pain.

Exposure in vivo (EXP) is an effective treatment to reduce pain-related fear and disability in chronic pain populations. Yet, it remains unclear how reductions in fear and pain relate to each other. This single-case experimental design study attempted to identify patterns in the individual responses to EXP and to unravel temporal trajectories of fear and pain. Daily diaries were completed before, during and after EXP. Multilevel modelling analyses were performed to evaluate the overall effect. Temporal effects were scrutinized by individual regression analyses and determination of the time to reach a minimal clinically important difference. Furthermore, individual graphs were visually inspected for potential patterns. Twenty patients with chronic low back pain and complex regional pain syndrome type I were included. On a group level, both fear and pain were reduced following EXP. Individually, fear was significantly reduced in 65% of the patients, while pain in only 20%. A decrease in fear was seen mostly in the first weeks, while pain levels reduced later or remained unchanged. Daily measurements provided rich data on temporal trajectories of reductions in fear and pain. Overall, reductions in fear preceded pain relief and seemed to be essential to achieve pain reductions.

Radiofrequency ablation of the basivertebral nerve in the treatment of chronic low back pain: analysis of a small clinical series

Objective. To evaluate the efficacy and safety of radiofrequency ablation of the basivertebral nerve in the treatment of chronic low back pain associated with Modic I and II changes according to MRI data.Material and Methods. The results of treatment of 19 patients with chronic low back pain syndrome in the lower back lasting 6 months or more were analyzed. Patients were treated with radiofrequency ablation of basivertebral nerve.Results. The duration of the manipulation averaged 28.0 ± 4.8 min. In all patients, a decrease in the Oswestry index by an average of 24.3 points (21.7 ± 5.2) was observed at 6 months after ablation of the basivertebral nerve. The intensity of the pain syndrome decreased immediately after the manipulation to 2.1 ± 1.1 cm on average, that is, by 71.2 %. According to the Beck Depression Scale, the patients showed signs of mild depression (subdepression) before the procedure (13.8 ± 3.6 points). When examined after 12 months, the patients showed an improvement in their psychoemotional state up to the normal values (3.4 ± 2.7 points). Subjective assessment of the condition of patients compared with the baseline showed that 16 (84.2 %) of them assessed their condition as a significant improvement with a significant regression of pain by more than 50 % at all stages of follow-up, and two patients (10.5 %) reported only a slight decrease in pain syndrome immediately after the procedure, followed by its resumption to the initial level.Conclusion. Using clear criteria for selection of patients for radiofrequency ablation of the basivertebral nerve, it can be argued that this method is effective in the treatment of chronic low back pain associated with Modic I and II changes according to MRI data. With the help of radiofrequency ablation, it is possible to achieve long-term remission of pain syndrome up to 12 months and more.

At my own pace, space, and place: a systematic review of qualitative studies of enablers and barriers to telehealth interventions for people with chronic pain.

Telehealth is a promising approach to support self-management with the potential to overcome geographical barriers. Understanding patient perspectives will identify practical challenges to delivering self-management strategies by telehealth. The aim of this study was to synthesize the perceptions of people with chronic musculoskeletal pain for engaging in interventions delivered using telehealth. We searched MEDLINE, Embase, CINAHL, LILACS, and PsycINFO databases. We included qualitative studies that explored perceptions or experiences or attitudes of people with chronic musculoskeletal pain engaging with telehealth. We assessed the methodological quality using the Critical Appraisal Skills Programme checklist. Meta-synthesis was guided by a thematic synthesis approach. The level of confidence of review findings was assessed using the Confidence in the Evidence from Reviews of Qualitative Studies (GRADE-CERQual). Twenty-one studies were included (n = 429). Telehealth comprised web-based, videoconference-based, telephone-based, video-based, and smartphone app-based programs delivered solely or combined. Chronic musculoskeletal conditions included people with knee or hip osteoarthritis, chronic low back pain, persistent pain (chronic joint pain or nonspecific chronic musculoskeletal pain), rheumatoid arthritis, and functional fatigue syndrome. The enablers for engaging in telehealth interventions were as follows: (1) "at my own pace, space, and place" and (2) empowered patient. Barriers to engaging in telehealth interventions were as follows: (1) impersonal, (2) technological challenges, (3) irrelevant content, and (4) limited digital (health) literacy. Telehealth interventions with well-designed interactive platforms, flexibility to fit patients' routine, and the broad availability of material may favor better engagement. Encouragement of self-efficacy is linked to successful telehealth-delivered self-management programs.

Comprehensiveness and validity of a multidimensional assessment in patients with chronic low back pain: a prospective cohort study

BackgroundChronic low back pain is a multidimensional syndrome affecting physical activity and function, health-related quality of life and employment status. The aim of the study was to quantify the cross-sectional and longitudinal validity of single measurement scales in specific construct domains and to examine how they combine to build a comprehensive outcome, covering the complex construct of chronic low back pain before and after a standardized interdisciplinary pain program.MethodsThis prospective cohort study assessed 177 patients using the Short Form 36 (SF-36), the Multidimensional Pain Inventory (MPI), the Symptom Checklist-90-Revised (SCL-90-R), the Oswestry Disability Index (ODI), and 2 functional performance tests, the Back Performance Scale (BPS) and the 6-Minute Walking Distance (6MWD). The comprehensiveness and overlap of the constructs used were quantified cross-sectionally and longitudinally by bivariate correlations, exploratory factor analysis, and effect sizes.ResultsThe mean age of the participants was 48.0 years (+/− 12.7); 59.3% were female. Correlations of baseline scores ranged from r = − 0.01 (BPS with MPI Life control) to r = 0.76 (SF-36 Mental health with MPI Negative mood). SF-36 Physical functioning correlated highest with the functional performance tests (r = 0.58 BPS, 0.67 6MWD) and ODI (0.56). Correlations of change scores (difference of follow-up – baseline score) were consistent but weaker. Factor analysis revealed 2 factors: “psychosocial” and “pain & function” (totally explained variance 44.0–60.9%). Psychosocial factors loaded strongest (up to 0.89 SCL-90-R) on the first factor, covering 2/3 of the explained variance. Pain and function (ing) loaded more strongly on the second factor (up to 0.81 SF-36 Physical functioning at follow-up). All scales showed improvements, with effect sizes ranging from 0.16–0.67.ConclusionsOur results confirm previous findings that the chronic low back pain syndrome is highly multifactorial and comprises many more dimensions of health and quality of life than merely back-related functioning. A comprehensive outcome measurement should include the predominant psychosocial domain and a broad spectrum of measurement constructs in order to assess the full complexity of the chronic low back syndrome. Convergence and divergence of the scales capture the overlapping contents and nuances within the constructs.

Assessment of the neuropathic component in a chronic low back pain syndrome

Background/Aim. Chronic low back pain syndrome (CLBPS) is the most common cause of functional disability and loss of working ability in developed countries. Some research shows that neuropathic pain (NP) is present in almost 50% of patients with CLPBS. The aim of this study was to determine the characteristics of NP and its impact on quality of life (QoL) in patients with CLBPS. Methods. Patients were tested using three questionnaires for NP: Pain Detect Questionnaire, Leeds Assessment of Neuropathic Symptoms and Signs, and Douleur Neuropathique 4 questions. Thirty-two patients diagnosed with NP based on current clinical criteria and with positive results for NP on all three NP questionnaires formed an experimental group. A control group consisted of 32 patients with CLBPS who did not fulfill clinical criteria for NP and were negative for NP on all three questionnaires. Hamilton depression and anxiety rating scales (Ham-D and Ham-A, respectively) and Short Form (SF)-36 questionnaire were also applied. Results. According to magnetic resonance imaging (MRI), disc herniation was typically detected in the experimental group, while degenerative changes were commonly found in the control group. Patients from the experimental group had significantly greater intensity of pain, pain radiation in the legs, and the pain was usually presented as episodes of sudden attacks with mild pain between them. The most distinctive features of NP were allodynia, electric shock sensation, and hypoesthesia to prick. Patients from the experimental group also had significantly higher depression and anxiety scores, as well as worse QoL compared to the control group, especially in mental domains. Predictors of worse QoL in the patients with CLBPS were a higher level of anxiety and depression. Conclusion. The presence of allodynia, electric shock-like sensations, and hypoesthesia to prick in patients with CLBPS suggest NP. CLBPS patients with NP had worse scores in mental domains of QoL compared to CLPBS patients without NP.

Interactions between Musculoskeletal Dysfunction, Emotional Distress and Cytokines in Patients with Chronic Low Back Pain Syndrome

Despite different treatment methods, for approximately 30% of patients acute back pain turns into chronic pain syndrome which accompanied by disability creates remarkable material damage to patients themselves, to health care and to the society. The aim of the study was to analyse the interaction between musculoskeletal dysfunction, emotional distress and related disability, and their underlying neuroimonological pathophysiological mechanisms, in patients with chronic low back pain syndrome. The subjects were 43 patients, mean age 45 ± 1.3 years, with clinical diagnosis of lumbar spine disk pathology with chronic low back pain syndrome and present manifestation of emotional distress. All patients had complex assessment that included lumbar spine and pelvic motor control tests, muscle and ligaments palpation tests, Hospital Anxiety and Depression Scale, PF subscale of SF-36 survey, Visual Analogue Scale, immunological analysis of blood to detect the level of cytokines. The results approved interaction (p &lt; 0.05) between motor control and palpation tests results, emotional distress features and pain intensity. Therefore musculoskeletal dysfunction in patients with chronic low back pain is connected both with physical and psycho-emotional factors, which has to be taken into account both when evaluating functional tests and during the treatment process. Clinically important finding is that limitation in physical activities in chronic low back pain patients are affected both by motor control impairment and depression symptoms, as well as pain intensity, which has to be remembered during rehabilitation planning process. Some of cytokines (TNF-a, IL-6, IL-8, IL-10, IL-2) correlated with emotional disturbances physical disturbances, pain syndrome characteristics and physical disability in patients with chronic low back pain. IL-10 and IL-8 appeared to be two of the most characteristic cytokines. It is interesting to note, that in literature studies have approved the role of IL-10 in the pathogenesis of chronic, widespread pain syndrome, but IL-8 has been shown in the role of the pathogenesis of radicular pain syndrome in patients with lumbar spine disk pathology [1, 2]. Studies of cytokines extend the understanding of bio-psycho-social aspects of chronic pain syndrome pathogenesis therefore improving process of assessment, clinical reasoning and therapy.Keywords: musculoskeletal dysfunction, emotional distress, chronic pain, cytokines.

Evaluation of the Results of Rehabilitation of Chronic Low Back Pain Syndrome in Physically Active and Inactive Patients During Leisure Time

Introduction: Movement is one of the main, modifiable factors (behaviour-dependent) that affects the health and quality of life of individuals and the entire population. Physical activity, including evidence-based active rehabilitation, is the subject of many studies on the prevention and treatment of spinal disorders, which are some of the most serious health problems. The largest group of people with spinal disorders are patients suffering from Nonspecific Low Back Pain (ang. Nonspecific Low Back Pain – NLBP), with kinesitherapy having the widest application in the chronic pain phase. A significant part of the research is devoted to the problem of movement in patients with chronic non-specific low back pain (CNLBP). One physiotherapy treatment method used in chronic low back pain syndrome is the DBC method. It is based on a detailed functional diagnosis, answers given to a standardized questionnaire, individualized treatment plans and active exercises with spinal resistance using specialized DBC equipment. Aim: The aim of this study was to evaluate the influence of leisure-time physical activity on the results of the DBC functional restoration program in patients with chronic, non-specific, low back pain after outpatient rehabilitation. The researchers tested the hypothesis that patients with regular physical activity attained better results of functional restoration compared to physically inactive participants. M aterials and Methods: The research group was comprised of one-hundred forty-seven participants. All subjects suffered from low back pain syndrome lasting for a period of at least three months without neurological symptoms. All symptoms were non-specific. The subjects were divided into two groups. Group 1 was comprised of participants who undertake regular physical activity for more than 45-minutes per exercise session, at least twice a week. Participants in Group 2 did not undertake any physical activity other than that resulting from everyday activities. The study commenced with an interview and standardized DBC questionnaire to get participants’ subjective assessment of the following parameters: current level of pain, functional limitations and scale of depression. A clinical trial was conducted prior to the measurement of objective parameters in order to exclude radicular pain (Lasegue test). Next, the objective parameters were measured: bioelectric activity of the lumbar erector spinae muscles (ang. surfasce electromyography – sEMG) on the right and left side in two positions: standing upright and leaning forward with straight legs. Also, DBC devices were used to measure the following range of motion of the lumbo-thoracic spine: flexion, extension, rotation and lateral flexion/bending. Upon completing the tests (Test 1) both groups were subject to active DBC therapeutic treatment. The therapy consisted of 12 meetings carried out within a 6 week period. Each session lasted for 1.5 hours. When the treatments ended testing was repeated for each group (Test 2). Results: Mean values of functional parameters of the lumbar spine were calculated for both groups. Statistical significance was determined between the preliminary (Test 1) and final (Test 2) tests. All the objective parameters in Group 1 showed statistically significant improvement post-therapy. Different results were observed in Group 2 for participants who did not perform regular physical activity. Although all parameters improved, only some achieved statistical significance. Significance between the two groups was also studied at the beginning of the experiment (Test 1) and after its completion (Test 2). There results showed no statistically significant difference in values of some objective parameters prior to the treatment, while some parameters differed. The treatment achieved a statistically significant improvement in the “active” group compared to the “inactive” one in almost every tested parameter excluding the extension. Significant differences between the groups were observed in the subjective parameters such as: functional limitations (ADL) (ang. Activity of Daily Living – ADL) and level of depression both in the first and last tests. Conclusions: Patients with chronic non-specific low back pain syndrome who remain physically active in leisure time and participated in the 6-week DBC rehabilitation program achieved a statistically significant improvement in the functional parameters of the spine. Patients with chronic non-specific low back pain syndrome who remain physically active in leisure time and participated in the 6-week DBC rehabilitation program improved more in the objective and subjective functional parameters of the spine in comparison with the inactive participants. Active leisure time contributes to the efficacy of physiotherapy for people with low back disorders.

Should kinesiology taping be used to manage pain in musculoskeletal disorders? An evidence synthesis from systematic reviews

Kinesiology taping has emerged as a relatively new treatment used for the management of pain in musculoskeletal disorders. The purpose of our review was to synthesise up-to-date evidence from systematic reviews on the clinical efficacy of kinesiology taping for managing musculoskeletal pain. Electronic databases (MEDLINE/PubMed, CENTRAL, AMED, CINAHL, PEDro, SPORTDiscus, OTseeker, Scopus, Web of Science, ProQuest, Open Thesis, EThOS) were searched for systematic reviews with or without meta-analysis published in English and non-English languages. Search findings were screened against eligibility criteria and systematic review data was extracted, tabulated and descriptively analysed. Our review included 43 systematic reviews (17 meta-analyses). Systematic reviewers reported a paucity of high-quality randomised controlled trials and that overall evidence was of “very low” to “moderate” quality. There were 32 systematic reviews published since 2015 and these provided tentative evidence that kinesiology taping was superior to no or minimal treatment, but not superior to conventional physical therapies for reducing pain and improving function in the short-term in myofascial pain syndrome, shoulder impingement syndrome, chronic low back pain, knee osteoarthritis and patellofemoral pain syndrome. There is insufficient high-quality evidence to determine the clinical efficacy of kinesiology taping for managing musculoskeletal pain with any certainty. We recommend that an enriched enrolment randomised withdrawal trial is needed to increase the trustworthiness of evidence to inform clinical practice. Healthcare professionals in musculoskeletal practice should view kinesiology taping as one of a variety of nonpharmacological approaches with uncertain efficacy that may be used in combination with the core treatment.

The Assessment of the Neuropathic Pain Scales and Disability in Patients with Chronic Low Back Pain Syndrome

The Assessment of the Neuropathic Pain Scales and Disability in Patients with Chronic Low Back Pain Syndrome

CHRNA5/CHRNA3 gene cluster is a risk factor for lumbar disc herniation: a case-control study

BackgroundLumbar disc herniation, a type of chronic low back pain syndrome, is caused by the lumbar intervertebral disk degeneration. Genetic variation in the CHRNA5/CHRNA3 has shown strong associations with smoking-related diseases. This study’s aim is to test whether single-nucleotide polymorphisms in the CHRNA5/CHRNA3 gene are associated with lumbar disc herniation risk.MethodsThe genotype frequency distributions of the polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism in 380 lumbar disc herniation patients (case group) and 400 healthy individuals (control group). Allelic, genotypic, and haplotype analyses were performed.ResultsWe found that the individuals with rs8040868 CT genotype had a 0.46-fold higher risk of lumbar disc herniation than those with rs8040868 TT genotype, in men group (OR = 0.46, 95% CI 0.25–0.84, p = 0.012). Also among women, rs8040868 CT + CC genotype still reduced the risk of lumbar disc herniation under the dominant model (OR = 0.50, 95% CI 0.28–0.89, p = 0.019). Haplotype analysis showed that compared with the CHRNA5 “TACAACCG” wild-type, the “TACACCCG” haplotype was found to be associated with a decreased risk of lumbar disc herniation (LDH) (OR = 0.79, 95% CI 0.63–1.00, p = 0.047), while, in the less than 50-year-old group, CHRNA5 “TACACCCG” increased the risk of LDH (OR = 1.46, 95% CI 1.01–2.13, p = 0.047).ConclusionsOur data suggest that gene variance in the CHRNA5/CHRNA3 is associated with risk of lumbar disc herniation in the case-control study.

Chronic Low Back Pain: Current Pharmacotherapeutic Therapies and a New Biological Approach

Chronic low back pain (CLBP) syndrome represents one of the leading causes of long-term disability worldwide. The prevalence of CLBP has been rising significantly in relation to increasing average life expectancy. CLBP results from chronification of acute low back pain. There are many factors contributing to the CLBP crisis; common etiopathogenetic factors include e.g., functional blockage of intervertebral joints. The treatment of CLBP is complex. An important part of treatment consists of pain pharmacotherapy, for which several groups of drugs are used. The problem lies in the side effects of many of these traditionally used medications. Therefore, new and safer treatment methods are being sought. Innovative options for CLBP pharmacology include injections containing collagen, which can be combined with other traditionally used drugs, which helps reduce dosages and increase the overall safety of CLBP therapy.

Evaluation of the Neuropathic Component of Chronic Low Back Pain.

Assessment of neuropathic pain in chronic low back syndromes is important. However, there is currently no gold standard for its diagnosis. The aim of this observational cross-sectional study was to assess the neuropathic component of pain in various chronic low back pain syndromes using a range of diagnostic tests. Included in this study were 63 patients with chronic axial low back pain (ALBP), 48 patients with chronic radicular syndromes (CRS) comprising 23 with discogenic compression (CDRS) and 25 with lumbar spinal stenosis (LSS), and 74 controls. PainDETECT questionnaire (PDQ), quantitative sensory testing (QST), and skin biopsy with evaluation of intraepidermal nerve fiber density (IENFD) were used to assess the neuropathic pain component. Positive PDQ (≥19) was obtained more frequently in patients with CDRS and LSS (26.1% and 12.0%, respectively) compared with patients with ALBP (1.6%, P<0.001). The proportion of patients with sensory loss confirmed by QST was lowest in the ALBP subgroup (23.8%) compared with CDRS (47.8%), and LSS (68.0%) subgroups (P<0.001). A reduction in IENFD was disclosed in a proportion of up to 52.0% of affected roots in patients with CRS. Neuropathic pain is quite frequent in CRS, and QST reveals sensory loss as a frequent abnormality in patients with CRS. Using a cut-off value of 19, PDQ identified a neuropathic component in a relatively low proportion of patients with CRS. CRS may be associated with a reduction in IENFD.

Back School programme for nurses has reduced low back pain levels: A randomised controlled trial.

(i) To examine patient lifting techniques used by nurses, and (ii) to evaluate an effectiveness of the Spine Care for Nurses programme in chronic nonspecific low back pain syndrome reduction and the execution of proper patient lifting techniques. Millions of nurses around the world suffer from occupational-related chronic nonspecific low back pain (chronic nonspecific low back pain syndrome). Generally, low back pain in nurses is a result of increased pressure on the spine and can be associated with improperly conducted patient lifting techniques. A randomised controlled trial was conducted among 137 nurses with chronic nonspecific low back pain syndrome. Participants were randomised into an experimental and control group (experimental group n=67, control group n=70). Nurses in the experimental group attended the Spine Care for Nurses programme for 3months. The programme consisted of didactic education, spine-strengthening exercises and education on safe patient handling techniques. The control group only received a brief written lifestyle guidance. The Zebris WinSpine Triple Lumbar examination was used to analyse nurses' patient lifting techniques (horizontal and vertical lifting). The lumbar pain intensity was measured with a 0-100 visual analogue scale. The pre-intervention average chronic nonspecific low back pain syndrome intensity score on visual analogue scale decreased from 49.3 to the postintervention score of 7.5. The correct execution of vertical lifting techniques in the experimental group increased from 8.91%-97.01% (control group: 8.57% pre-intervention test and postintervention test 11.42%). The horizontal patient lifting technique pre-intervention increased from 10.44%-100% correct execution in the experimental group (control group: pre-intervention test 10.00% and postintervention test 11.42%). The Spine Care for Nurses programme significantly reduced chronic nonspecific low back pain syndrome and increased the number of properly executed horizontal and vertical patient lifting techniques in nurses. We recommend that healthcare organisations should consider the implementation of regular Spine Care for Nurses programmes as successful low back injury prevention programmes.
