Relato de caso de lombalgia inflamatória com extenso comprometimento anatômico-funcional: a importância de uma adequada abordagem da dor lombar na Atenção Primária à Saúde / Case report of inflammatory low back pain with extensive anatomical-functional impairment: The importance of an adequate approach to low back pain in Primary Care / Presentación de un caso de lumbalgia inflamatoria con afectación anatómico-funcional extensa: La importancia de un abordaje adecuado de la lumbalgia en Atención Primaria de Salud

Introdução: A lombalgia é uma condição prevalente e que apresenta importante impacto na capacidade funcional e na qualidade de vida, sendo a sua correta abordagem na Atenção Primária à Saúde fundamental para a identificação e o estabelecimento de um diagnóstico etiológico precoce de possíveis patologias que possam estar relacionadas a desfechos mórbidos e a graves limitações funcionais. Apresentação do caso: Paciente de 56 anos, sexo masculino, hipertenso, foi encaminhado para serviço especializado de reumatologia com histórico de lombalgia havia mais de 20 anos. Ao exame físico foi constatada presença de deformidades da coluna vertebral e extensa limitação de movimentos. Exames radiográficos mostravam esclerose de articulações sacroilíacas, osteopenia difusa e coluna vertebral em aspecto de "bambu". Conclusões: Constata-se a importância de que na abordagem das lombalgias na atenção primária se busque o reconhecimento de possíveis etiologias graves e potencialmente incapacitantes que possam estar subjacentes à queixa de dor lombar. Com esse objetivo, é fundamental o reconhecimento das chamadas red flags relacionadas às lombalgias, além de sua caracterização como mecânica ou inflamatória. Perante a atuação da atenção primária no oferecimento de um cuidado pautado na integralidade e na prevenção de agravos, reafirma-se a importância de uma avaliação clínica pormenorizada das lombalgias nesse nível de atenção à saúde.

Introduction: Low back pain is a prevalent condition that has an important impact on functional capacity and quality of life, and its correct approach in Primary Care is fundamental to the identification and establishment of an early etiological diagnosis of possible pathologies that may be related to outcomes morbid conditions and serious functional limitations. Case presentation: 56-year-old male patient, hypertensive, referred to a specialized rheumatology service with a history of low back pain for over 20 years. Physical examination revealed the presence of spinal deformities and extensive movement limitations. Radiographic examinations showing sclerosis of the sacro-iliac joints, diffuse osteopenia and a "bamboo" appearance of the spine. Conclusions: It is important that in the approach of low back pain in Primary Care, we seek to recognize possible serious and potentially disabling etiologies that may underlie the complaint of low back pain. For that, it is essential to recognize the so-called "red flags" related to low back pain, in addition to its characterization as mechanical or inflammatory. Given the role of Primary Care in offering care based on integrality and in the prevention of injuries, the importance of a detailed clinical assessment of low back pain at this level of health care is reaffirmed.

Hydrogen-releasing magnesium hydrogel mitigates post laminectomy epidural fibrosis through inhibition of neutrophil extracellular traps.

Epidural fibrosis is a primary contributor to the failure of laminectomy surgeries, leading to the development of failed back surgery syndrome (FBSS). Post-laminectomy, neutrophils infiltrate the surgical site, generating neutrophil extracellular traps (NETs) that contribute to epidural fibrosis. Reactive oxygen species (ROS) play a pivotal role in mediating NETs formation. Molecular hydrogen, recognized for its selective antioxidant properties and biosafety, emerges as a potential therapeutic gas in suppressing epidural fibrosis. In this study, we developed an in-situ hydrogen release hydrogel that inhibits the formation of NETs and mitigates epidural scarring. Biodegradable magnesium (Mg) microspheres served as a hydrogen source, coated with PLGA to regulate hydrogen release. These microspheres (Mg@PLGA) were then incorporated into a PLGA-PEG-PLGA thermosensitive hydrogel (Mg@PLGA@Gel), providing a surgical implant for sustained, long-term hydrogen release. In vitro experiments confirmed the biocompatibility of the system, demonstrating that hydrogen produced by Mg@PLGA effectively neutralizes neutrophil intracellular ROS and inhibits NETs formation. Histological analyses, including H&E staining, MRI, Masson staining, and immunohistochemistry, collectively indicate that Mg@PLGA@Gel is biocompatible and effectively inhibits epidural fibrosis post-laminectomy. Furthermore, Mg@PLGA@Gel inhibits ROS accumulation and NETs formation at the surgical site. These findings suggest that Mg@PLGA@Gel ensures continuous, therapeutic hydrogen concentration, providing relief from epidural fibrosis in a laminectomy mouse model. STATEMENT OF SIGNIFICANCE: •The hydrogen-releasing hydrogel combines the therapeutic effects of a physical barrier with immunomodulation. •In situ-generated molecular hydrogen scavenges ROS caused by surgical stress and suppresses NETs formation. •The hydrogen-releasing hydrogel is demonstrated to exhibit high biocompatibility and inhibit epidural scar formation in vivo.

Exploring low back and pelvic pain challenges: Administrative insights into prevalence during pregnancy among 2016-2021 South Carolina Medicaid beneficiaries.

BACKGROUND: Musculoskeletal changes occur during pregnancy; one-half of pregnant women experienced low back pain and/or pelvic pain during pregnancy. Prescription opioid use for Medicaid enrolled pregnant women has increased dramatically due to severe low back pain/pelvic pain. OBJECTIVES: This study aimed to explore the prevalence of low back pain/pelvic pain and related risk factors among a broader population. DESIGN: This is a retrospective cohort study. METHODS: This study utilized de-identified Medicaid claims data provided by the South Carolina Revenue and Fiscal Affairs Office, including individuals who gave birth between 2016 and 2021 during pregnancy. Low back pain/pelvic pain and a group of musculoskeletal risk factors were identified with International Classification of Diseases v10. Comparisons were made for the prevalence of low back pain and pelvic pain between those with pregnancy-related musculoskeletal risk and those without. RESULTS: Among 167,396 pregnancies, 65.6% were affected by musculoskeletal risk factors. The overall prevalence of low back pain was 15.6%, and of pregnancy-related pelvic pain was 25.2%. The overall prevalence for either low back pain or pelvic pain was 33.3% (increased from 29.5% in 2016 to 35.3% in 2021), with 24.6% being pregnancy-induced. Pregnancies with musculoskeletal risk factors were more likely to be diagnosed with low back pain (20.7% versus 5.7%, p < 0.001) or pelvic pain (35.3% versus 6.0%, p < 0.001) than those without. CONCLUSION: This study found a very high prevalence of musculoskeletal risk and a high prevalence of low back pain or pelvic pain, with an increasing trend, among South Carolina pregnancies enrolled in Medicaid during the period 2016-2021. Most of the diagnosed low back pain or pelvic pain were pregnancy induced. Musculoskeletal risk factors were associated with low back pain or pelvic pain.

A community health-coaching referral program following discharge from treatment for chronic low back pain - a qualitative study of the patient's perspective.

BACKGROUND: Global policy and guidelines for low back pain (LBP) management promote physical activity and self-management yet adherence is poor and a decline in outcomes is common following discharge from treatment. Health coaching is effective at improving exercise adherence, self-efficacy, and social support in individuals with chronic conditions, and may be an acceptable, cost-effective way to support people in the community following discharge from treatment for LBP. AIM: This qualitative study aimed to understand which aspects of a community over-the-phone health-coaching program, were liked and disliked by patients as well as their perceived outcomes of the service after being discharged from LBP treatment. METHODS: A purposive sampling approach was used to recruit 12 participants with chronic LBP, from a large randomised controlled trial, who were randomly allocated to receive a health coaching program from the Get Healthy Service® in Australia. Semi-structured interviews were conducted, and a general inductive thematic analysis approach was taken. RESULTS: The main themes uncovered regarding the intervention included the positive and negative aspects of the health coaching service and the relationship between the participant and health coach. Specifically, the participants spoke of the importance of the health coach, the value of goal setting, the quality of the advice received, the benefits of feeling supported, the format of the coaching service, and LBP-specific knowledge. They also reported the health coach and the coaching relationship to be the primary factors influencing the program outcomes and the qualities of the coaching relationship they valued most were connection, communication, care, and competence. The sub-themes uncovered regarding the outcomes of the intervention included positive impacts (a greater capacity to cope, increased confidence, increased motivation and increased satisfaction) and negative impacts (receiving no personal benefit). CLINICAL IMPLICATIONS: In an environment where self-management and self-care are becoming increasingly important, understanding the patient's experience as part of a coaching program is likely to lead to improved quality of health coaching care, more tailored service delivery and potentially more effective and cost-effective community-based care for individuals with chronic LBP in the community after being discharged from treatment. TRIAL REGISTRATION: The GBTH trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000889954) on 10/9/2020. Ethical approval was prospectively granted by the Western Sydney Local Health District Human Research and Ethics Committee (2020/ETH00115). Written informed consent was obtained from all participants. The relevant sponsor has reviewed the study protocol and consent form.

The link between childhood physical activity enjoyment and adult kinesiophobia in individuals with chronic low back pain.

BACKGROUND: This study aimed to investigate the relationship between childhood physical activity enjoyment and current kinesiophobia among individuals with chronic low back pain (CLBP), considering the mediating influence of adult physical activity. METHODS: We recruited 648 adults (474 males, 174 females) with CLBP through an online platform. Of these, 99.1% (n = 642) were aged 18-60 years, and 0.9% (n = 6) were older than 60 years. Childhood physical activity enjoyment was retrospectively assessed using a single-item question to gauge participants' enjoyment during primary school. Kinesiophobia was measured with the 11-item Tampa Scale for Kinesiophobia (TSK-11), and physical activity was assessed focusing on walking, moderate, and vigorous physical activities. Age, sex, education, and income served as control variables in the analysis. RESULTS: A significant negative association was found between childhood physical activity enjoyment and adult kinesiophobia. Additionally, childhood physical activity enjoyment was positively associated with adult physical activity across the three types of physical activities. In the adjusted mediation model, walking was identified as the only statistically significant partial mediator. CONCLUSION: The findings highlight the long-term protective role of childhood physical activity enjoyment against the development of kinesiophobia in adulthood. Walking, in particular, holds unique therapeutic potential, emphasizing the importance of fostering physical activity enjoyment early in life for sustained physical activity and reduced risk of kinesiophobia among CLBP patients.

Association between meeting 24-hour movement behavior guidelines and quality of life in adolescents with idiopathic scoliosis.

BACKGROUND: Meeting the 24-hour movement behavior (24-HMB) guideline helps enhance quality of life (QOL) of adolescents. This study aimed to assess the associations between the 24-HMB (physical activity, screen time, sleep) and QOL among adolescents with idiopathic scoliosis. METHODS: A cross-sectional study was conducted between September 2021 and September 2023. 24-HMB, QOL and demographic variables were collected through a self-reported questionnaire. Linear regression models and stratified analyses were used to explore statistical associations between the 24-HMB and QOL. RESULTS: A total of 1073 participants aged 10-18 years with a spinal Cobb angle between 10° and 40° were included. Overall, 20 participants (1.9%) met all three behavioral guidelines, and 272 participants (25.3%) met none. Compared to those who did not meet any of the guidelines, adolescents meeting both screen time and sleep duration (ß = 4.10, 95% CI: 2.02-6.18, P < 0.001) and all 3 guidelines (ß = 4.39, 95% CI: 0.27-8.51, P = 0.037) had higher QOL scores. Stratified analyses showed that the above associations were more pronounced in adolescents without back pain or with good self-image. CONCLUSIONS: These findings highlight the importance of adopting and maintaining healthy behavioral habits in order to improve QOL among adolescents with idiopathic scoliosis, especially in those without back pain or with good self-image.

Characterizing Acute Low Back Pain in a Community-Based Cohort: Results from a Feasibility Cohort Study.

Introduction: Acute low back pain (LBP) is a common experience; however, the associated pain severity, pain frequency, and characteristics of individuals with acute LBP in community settings have yet to be well understood. In this manuscript, two acute-LBP severity categorization definitions were developed: 1) pain impact frequency (impact-based) and 2) pain intensity (intensity-based) severity categories. The purpose of this manuscript is to describe and then compare these acute-LBP severity groups in the following characteristics: 1) sociodemographic, 2) general and physical health, and 3) psychological using a feasibility cohort study. Methods: This cross-sectional study used baseline data from 131 community-based participants with acute LBP (<4 weeks duration before screening and ≥30 pain-free days before acute LBP onset). Descriptive associations were calculated as prevalence ratios of categorical variables and Hedges' g for continuous variables. Results: Our analyses identified several large associations for impact-based and intensity-based categories with global mental health, global physical health, STarT Back Screening Tool risk category, and general health. Larger associations were found with social constructs (racially and ethnically minoritized, performance of social roles, and isolation) when using the intensity-based versus impact-based categorization. Discussion: This study adds to the literature by providing standard ways to characterize community-based individuals experiencing acute-LBP. The robust differences observed between these categorization approaches suggest that how we define acute-LBP severity is consequential; these different approaches may be used to improve the early identification of factors potentially contributing to the development of chronic-LBP.

Comparison of the Effectiveness of Traditional Motorized Traction and Non-surgical Spinal Decompression Therapy Added to Conventional Physiotherapy for Treatment of Chronic Low Back Pain.

BACKGROUND: There are a limited number of studies comparing traditional motorized traction and non-surgical spinal decompression with other treatment options such as conventional motor traction in the treatment of low back pain caused by lumbar discopathy. This retrospective study aimed to compare the effectiveness of these treatments. METHODS: The retrospective data of patients diagnosed with lumbar discopathy who underwent physical therapy in our clinic were reviewed. Demographic data, duration of their symptoms, physical examination findings, lumbosacral magnetic resonance imaging (MRI) reports, method and duration of treatment, and visual analog scale (VAS) and Oswestry Disability Index (ODI) results were recorded. RESULTS: A total of 160 patients met the inclusion criteria. Their mean age was 44.6±12.4 (range 21-65) years, 57.5% (n=92) were female, and 42.5% (n=68) were male. There were no differences between the conventional physiotherapy, motorized traction, and spinal decompression groups in terms of age, duration of symptoms, and the number of sessions (p>0.05). In all three groups, the mean scores of VAS and ODI were significantly decreased in the pre-and post-treatment comparisons (p<0.005). The rates of change in VAS and ODI were higher in the traction group and spinal decompression group compared to the conventional treatment (p<0.005). CONCLUSION: In patients with subacute and chronic lumbar discopathies, motorized traction and spinal decompression treatments added to conventional treatment were found to be more effective than conventional treatment alone. The results of spinal decompression and conventional motorized traction treatments appear to be similar.

Musculoskeletal symptomatology in skeletally immature students carrying heavy backpacks: a cross-sectional study.

Background: Young students with skeletal immaturity report an increasing number of musculoskeletal symptoms associated with daily use of heavy backpacks. This cross-sectional study investigated the relationship between heavy backpack use and reports of pain. Methods: Data were collected from 300 students aged 11 to 18 at the University of Toronto Schools. Results: Students, on average, carried 15.9% of their body weight. 54% of students reported physiological complaints, primarily back, shoulder, neck, and leg pain. Backpack weight as a % of body weight was strongly associated with pain complaints. Younger students and those with longer commutes were more likely to report heavy backpacks (50% compared to 22.6% of older students, p< .001) and pain. Conclusion: Carrying heavy backpacks could result in increased musculoskeletal complaints in young students. Findings suggest that even the upper bound of currently recommended guidelines (20% of body weight) may be too high, especially for younger children.

La symptomatologie musculosquelettique chez des étudiants dont le squelette est immature, et qui portent des sacs à dos lourds : une étude transversale. Contexte: Les jeunes étudiants souffrant d'immaturité squelettique signalent un nombre croissant de troubles musculosquelettiques des symptômes associés à l'utilisation quotidienne de sacs à dos lourds. Cette étude transversale a examiné la relation entre l'utilisation de sacs à dos lourds et les signalements de douleurs. Méthodes: Les données ont été recueillies auprès de 300 étudiants âgés de 11 à 18 ans dans les écoles de l'Université de Toronto. Résultats: Les étudiants, en moyenne, portaient 15,9 % de leur poids corporel. 54 % des élèves ont signalé des troubles physiologiques, principalement des douleurs au dos, aux épaules, au cou et aux jambes. Le poids du sac à dos exprimé en pourcentage du poids corporel était fortement associé aux douleurs. Les étudiants plus jeunes et ceux qui ont des trajets plus longs étaient plus susceptibles de déclarer avoir des sacs à dos lourds (50 % comparativement à 22,6 % des étudiants plus âgés, p< .001), ainsi que des douleurs. Conclusion: Le port de sacs à dos lourds pourrait entraîner une augmentation des plaintes musculosquelettiques chez les jeunes élèves. Les résultats suggèrent que même la limite supérieure des recommandations actuelles (20 % du poids corporel) pourrait être trop élevée, en particulier pour les jeunes enfants.

Systematic Review and Meta-analysis of Stimulation of the Medial Branch of the Lumbar Dorsal Rami for the Treatment of Chronic Low Back Pain.

INTRODUCTION: Chronic low back pain (CLBP) is often associated with impaired motor control and degeneration of the lumbar multifidus muscles. Several studies have reported on the utility of multifidus or medial branch stimulation as a treatment. We present a systematic review and meta-analysis of studies reporting on the change in low back pain intensity with multifidus stimulation. MATERIALS AND METHODS: A comprehensive literature search was conducted from 2010 to 2022 for randomized controlled trials or prospective reports in adults with CLBP, treated with multifidus or medial nerve stimulation through implanted or percutaneous device. Mean change (standard error) in pain intensity was extracted and data synthesized using a mixed effects regression with a random intercept for the study to account for repeated time points. RESULTS: A total of 419 participants were enrolled in six studies; there were 25 effects (one to six time points per study), with follow-ups ranging from 1.5 to 48 months. The weighted pooled mean effect was a reduction in pain intensity (0-10 scale) of 2.9 units (95% CI: 2.1-3.7). The 95% prediction interval was a reduction in pain intensity of 0.6 to 5.2 units. The estimated probability of a reduction in pain of >two units in a new similar study is 0.84 (0.68-0.98). Meta-regression revealed that a longer follow-up time was associated with greater reductions in pain (0.25 units [0.16-0.34] per six months). CONCLUSIONS: Medial branch stimulation for the treatment of CLBP shows a high probability of a clinically significant change in pain intensity. Longer duration of stimulation was associated with decreased low back pain intensities.

Multidevice spinal cord stimulation trials: shared decision making in the era of multiple neuromodulation paradigms.

Aim: There is a lack of evidence-based standards for matching spinal cord stimulation (SCS) paradigm to individual patients. We aim to determine the feasibility and safety of a new alternative trial strategy, a sequential multidevice trial.Materials & methods: A retrospective analysis was performed on 116 patients who underwent SCS trials, single device or sequential multidevice (tonic and high-frequency), for chronic low back pain to assess feasibility and compare trial-to-implantation rate and explantation rate.Results: Multidevice SCS trials are feasible and safe. There was no statistically significant difference in the trial-to-implantation and explantation rates between the two groups.Conclusion: Multidevice SCS trial, prioritizing patient preference, may serve as an alternative trial strategy to improve long-term success of SCS.

Spinal cord stimulation plays an important role in the management of chronic low back pain refractory to conventional treatment. The current standard of practice is to try one device for 3­7 days prior to implantation. In the setting of increasing number of device options, we believe that a new trial method may be necessary to improve patient exposure to different options, thus improving informed decisions based on their personal experiences. Our study supports that this new trial method with different devices is feasible and safe.

Physiotherapy-led care versus physician-led care for persons with low back pain: A systematic review.

OBJECTIVE: To summarise the evidence on the effect of physiotherapy-led versus physician-led care on clinical outcomes, healthcare use, and costs in persons with low back pain. DATA SOURCES: PubMed, Web of Science, CINAHL, Embase, and PEDro were systematically searched with the latest search performed in July 2024. Reference lists of articles were hand-searched. REVIEW METHODS: Studies comparing clinical outcomes, healthcare use, or costs between adults with low back pain first consulting a physiotherapist and those first consulting a physician were included. Methodological quality was assessed with the Newcastle-Ottawa Scale. Study design, clinical setting, patient characteristics, and group effects were extracted. Findings on outcomes assessed in two or more studies were synthesised narratively. Certainty of evidence was determined using the GRADE approach. RESULTS: Eighteen studies comprising 1,481,980 persons with low back pain were included. Most studies were non-randomised retrospective or prospective cohort studies. In primary care (15 studies), consistent evidence, though of mostly very low certainty, indicated that physiotherapy-led care leads to higher patient satisfaction, less use of medication, injections and imaging, fewer physician's visits, lower total healthcare costs, and less sick leave compared to physician-led care, without increased harm. In emergency care (three studies), evidence of very low certainty showed that physiotherapy-led care leads to shorter waiting and treatment times, and fewer hospital admissions. CONCLUSION: Physiotherapy-led care is a clinically, time- and cost-effective care pathway for low back pain, although the certainty of evidence was overall very low. Further high-quality research with a greater focus on clinical outcomes is warranted.

Comprehensive Analysis of Treatment Approaches for Lumbar Disc Herniation: A Systematic Review.

Lumbar disc herniation is a common disorder that has an important impact on the quality of life and daily activities of those affected. It is defined as the displacement of the nucleus pulposus beyond the intervertebral space. This systematic review aims to evaluate and compare the efficacy of several treatment modalities, including conservative, pharmaceutical, and surgical interventions. The data sources utilized were PubMed, Google Scholar, Embase, and Cochrane. We conducted a systematic review of English-language articles published between 2019 and 2024, using the PRISMA guidelines. A total of 720 studies were identified during the search. Following the evaluation of the title, abstract, and full text, and the application of exclusion criteria, a total of 15 studies met the requirements for inclusion in the analysis. The results indicate that although conservative treatment is frequently successful in providing immediate relief of symptoms, surgical interventions may be required for patients experiencing neurological deficits or those who do not respond to conservative treatments. One limitation of this systematic review is the inclusion of a limited number of studies, which may affect the generalizability of the findings. Additionally, the review was restricted to English-language publications from 2019 to 2024, potentially excluding relevant research published in other languages or outside this timeframe.

Assessing the Evidence for Nonobstetric Risk Factors for Deformational Plagiocephaly: Systematic Review and Meta-Analysis.

BACKGROUND: Plagiocephaly is defined as an asymmetrical distortion of the skull, resulting in an oblique trapezoid or parallelogram head shape. Deformational plagiocephaly (DP) is caused by forces acting on one side of the back of the head, distorting normal skull symmetry. OBJECTIVE: The aims of this systematic review and meta-analysis were to critically assess the evidence for nonobstetric risk factors for DP and to make evidence-based recommendations for reducing the prevalence of DP. METHODS: The selection criterion was studies reporting risk factors for DP. Case reviews, case series, expert opinions, and systematic reviews were excluded. PubMed and Web of Science were searched from August 21, 2010, to August 21, 2022. Publication bias was assessed using funnel plots. Meta-analyses were presented using forest plots. RESULTS: A total of 19 studies (cohort studies: n=13, 68%; case-control studies: n=5, 26%; and cross-sectional studies: n=1, 5%) with a total of 14,808 participants were included. Of the 43 investigated potential nonobstetric factors, 16 (37%) were associated with DP. Of these 16 factors, 12 (75%) had odds ratios (ORs) with 95% CIs not crossing 1: insufficient vitamin D intake (OR 7.15, 95% CI 3.77-13.54), head position preference (OR 4.75, 95% CI 3.36-6.73), bottle-only feeding (OR 4.65, 95% CI 2.70-8.00), reduced tummy time (OR 3.51, 95% CI 1.71-7.21), sleeping position (OR 3.12, 95% CI 2.21-4.39), fewer motor milestones reached by the age of 6 months (OR 2.56, 95% CI 1.66-3.96), obesity (OR 2.45, 95% CI 1.02-5.90), maternal education level (OR 1.66, 95% CI 1.17-2.37), male sex (OR 1.51, 95% CI 1.07-2.12), formula feeding (OR 1.51, 95% CI 1.00-2.27), head circumference (OR 1.22, 95% CI 1.06-1.40), and mechanical ventilation (OR 1.10, 95% CI 1.00-1.14). No evidence of publication bias was detected. CONCLUSIONS: This study provides a comprehensive assessment of the nonobstetric factors associated with DP and presents 11 evidence-based recommendations for reducing its prevalence. The primary limitation is that only publication bias was assessed. TRIAL REGISTRATION: PROSPERO CRD42020204979; https://www.crd.york.ac.uk/prospero/display_record.php? ID=CRD42020204979.

Communicating safety-netting information in primary care physiotherapy consultations for people with low back pain.

BACKGROUND: Safety-netting involves communicating information to patients about diagnostic uncertainty, the likely time-course of their condition and how to appropriately seek help from a healthcare professional if their condition persists or worsens. Little is known about how physiotherapists communicate safety-netting information to people with low back pain (LBP). OBJECTIVES: This research aimed to use a Safety-Netting Coding Tool (SaNCoT) to explore how physiotherapists communicate safety-netting information to people with LBP. METHODS: The SaNCoT was used to conduct a secondary analysis of audio-recordings and transcripts from 79 primary care physiotherapy consultations (41 initial and 38 follow-up) involving 12 physiotherapists and 41 patients with LBP in Southern England. Quantitative data from the SaNCoT were analysed descriptively. FINDINGS: The study found evidence of diagnostic uncertainty in 53 (67%) appointments and no examples of physiotherapists providing patients with specific information about their condition time-course. Eight patients were given safety-netting advice, but most (57.9%, n = 11) episodes of safety-netting advice did not include specific signs and symptoms for patients to monitor. Potential missed opportunities for safety-netting advice were identified in 19 appointments (24.1%) which tended to relate to the patient's associated leg symptoms but also included possible serious pathology. CONCLUSION: The SaNCoT was successfully used to measure safety-netting communication within physiotherapy consultations and found missed opportunities for providing clear safety-netting advice. Physiotherapists can use the findings to reflect on how they can provide clear safety-netting information to patients with LBP to effectively support patients to self-manage and help them seek appropriate care if their condition deteriorates.

Targeting nerve growth factor for pain relief: pros and cons.

Nerve growth factor (NGF) is a neurotrophic protein that has crucial roles in survival, growth and differentiation. It is expressed in neuronal and non-neuronal tissues. NGF exerts its effects via two types of receptors including the high affinity receptor, tropomyosin receptor kinase A and the low affinity receptor p75 neurotrophin receptor highlighting the complex signaling pathways that underlie the roles of NGF. In pain perception and transmission, multiple studies shed light on the effects of NGF on different types of pain including inflammatory, neuropathic, cancer and visceral pain. Also, the binding of NGF to its receptors increases the availability of many nociceptive receptors such as transient receptor potential vanilloid 1, transient receptor potential ankyrin 1, N-methyl-D-aspartic acid, and P2X purinoceptor 3 as well as nociceptive transmitters such as substance P and calcitonin gene-related peptide. The role of NGF in pain has been documented in pre-clinical and clinical studies. This review aims to shed light on the role of NGF and its signaling in different types of pain.

Effects of a new continuous nursing program on the short-term and long-term low back pain in patients after UBED: a retrospective study based on 282 patients.

Background: Unilateral biportal endoscopic discectomy (UBED) is a widely accepted minimally invasive surgery for the treatment of lumbar degenerative diseases. However, some patients continue to have persistent low back pain (LBP) symptoms in the short and long term after surgery, which may be related to improper postoperative nursing and rehabilitation of patients. Further research is needed to determine whether continuous nursing can improve the symptoms of patients after UBED. Methods: This study retrospectively enrolled 282 lumbar disc herniation (LDH) patients who underwent UBED in our hospital from January 2019 to January 2022. The patients were divided into two groups according to whether they accepted the continuous nursing program: 147 patients in the traditional nursing group and 135 patients in the continuous nursing group. Demographic characteristics, radiological parameters, and follow-up data of the patients were collected. Finally, the risk factors of LBP after UBED were analyzed. Results: The visual analog scale (VAS) score of LBP in the continuous nursing group was 0.97 ± 1.159 at 3 months and 0.61 ± 0.954 at 12 months after operation, and VAS of leg pain was 0.23 ± 0.421 at 12 months after operation, which were better than those in the traditional nursing group (1.51 ± 1.313, 1.10 ± 1.076, 0.68 ± 0.788, respectively, p < 0.001) The Oswestry disability index (ODI) score of the continuous nursing group was lower than that of the traditional nursing group at 12 months after operation (7.36 ± 6.526 vs. 12.43 ± 6.942, p < 0.001). The rehabilitation completion (7.98 ± 1.857), efficacy satisfaction (9.13 ± 1.101), and re-herniation worry scores (1.97 ± 1.217) in the continuous nursing group were better than those in the traditional nursing group (4.14 ± 3.066, 8.28 ± 1.240, 2.79 ± 1.973, respectively, P < 0.001). The re-herniation rate within 1 year was similar between the two groups (3/135 vs. 2/147, p = 0.673). No incision infection occurred. Multivariate regression analysis showed that risk factors for persistent LBP at 3-month follow-up were degenerative disc [odds ratio (OR): 2.144, CI: 1.306-3.519, p = 0.03], Pfirrmann grade (OR: 3.073, CI: 1.427-6.614, p = 0.04), and surgical time (OR: 0.969, CI: 0.937-1.003, p = 0.74). At the 12-month follow-up, the risk factors for persistent LBP were preoperative VAS of the legs (OR: 1.261, CI: 1.000-1.591, p = 0.05) and Pfirrmann grade (OR: 3.309, CI: 1.460-7.496, p = 0.04). Conclusion: Continuous nursing programs can improve the symptoms of short-term and long-term persistent LBP in patients after UBED, enhance the completion of rehabilitation training after UBED, alleviate patients' concerns about recurrence, and improve patients' satisfaction.

Magnitude of changes in muscle endurance in the Biering-Sorensen test and changes in balance in subjects with LBP treated with muscle energy techniques.

Purpose: Manual therapy is used as a conservative treatment for people with low back pain (LBP). The scale of the problem encourages the search for the most effective methods to assess of manual treatment. Therefore, the aim of the study was to investigate magnitude of changes in muscle endurance using the Biering-Sorensen test (BST) and to analyse balance in patients with LBP treated with ERS and FRS muscle energy techniques (MET). Methods: The study included fifteen men with LBP (mean age: 42 years) working as automotive assemblers. Endurance of the biceps femoris (BF), gluteus maximus (GM) and erector spinae (ES) muscles were analysed using sEMG during the BST. The level of experienced pain, degree of disability and postural stability were also examined. Results before and after a three-week treatment cycle using MET were compared. Results: The MET therapy resulted in a reduction in pain ( p = 0.001), an improvement in the degree of disability ( p < 0.001) and an increase in the duration of the BST ( p < 0.001). After therapy, the values of the NMFs parameter indicating the degree of fatigue increased, i.e., ES muscle endurance increased, both right ( p = 0.004) and left ( p < 0.001). There was also a statistically significant decrease in the centre of pressure (COP) movement velocity in balance tests. Conclusions: The use of MET in patients with LBP increases muscle endurance, improves postural balance, and reduces pain levels on the VAS and disability levels according to the ODI. MET appears to be a good tool for preventing LBP.

Validating the Accuracy of a Patient-Facing Clinical Decision Support System in Predicting Lumbar Disc Herniation: Diagnostic Accuracy Study.

BACKGROUND: Low back pain (LBP) is a major cause of disability globally, and the diagnosis of LBP is challenging for clinicians. OBJECTIVE: Using new software called Therapha, this study aimed to assess the accuracy level of artificial intelligence as a Clinical Decision Support System (CDSS) compared to MRI in predicting lumbar disc herniated patients. METHODS: One hundred low back pain patients aged ≥18 years old were included in the study. The study was conducted in three stages. Firstly, a case series was conducted by matching MRI and Therapha diagnosis for 10 patients. Subsequently, Delphi methodology was employed to establish a clinical consensus. Finally, to determine the accuracy of the newly developed software, a cross-sectional study was undertaken involving 100 patients. RESULTS: The software showed a significant diagnostic accuracy with the area under the curve in the ROC analysis determined as 0.84 with a sensitivity of 88% and a specificity of 80%. CONCLUSIONS: The study's findings revealed that CDSS using Therapha has a reasonable level of efficacy, and this can be utilized clinically to acquire a faster and more accurate screening of patients with lumbar disc herniation.
