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.

Conclusiones: Es importante que al abordar la lumbalgia en Atención Primaria de Salud busquemos reconocer las posibles etiologías graves y potencialmente incapacitantes que pueden subyacer a la queja de lumbalgia. Con este objetivo, es fundamental reconocer las llamadas "banderas rojas" relacionadas con la lumbalgia, además de su caracterización como mecánica o inflamatoria. Dado el papel de Atención Primaria de Salud a la hora de ofrecer una atención basada en la integralidad y prevención de enfermedades, se reafirma la importancia de una evaluación clínica detallada de la lumbalgia en este nivel de atención sanitaria.

Postural and Lumbopelvic Control: Crucial Factors in the Functionality of Patients with Low Back Pain-A Descriptive Cross-Sectional Study.

Background: Low back pain (LBP) is one of the most prevalent musculoskeletal disorders in adults worldwide. Alterations in postural and lumbopelvic control and functionality appear to be determining factors in its resolution. Methods: A cross-sectional study was performed. Patients with LBP were enrolled. Lumbar pain; postural control (PC), total area of the center of pressure (TACOP), and the velocity of the center of pressure (VCOP); lumbopelvic control (LPC); and functionality were evaluated. Statistical tests were implemented to determine differences between sex and age and correlation models among the variables. Results: Thirty adult patients with LBP were analyzed. A strong relationship was found between pain and functionality [r = 0.64; p < 0.001]. A moderate relationship was found between pain and TACOP [r = 0.395; p = 0.031]. A moderate relationship was observed between TACOP and functionality [0.413; p = 0.023] and between LPC and TACOP [r = 0.416; p = 0.001]. Conclusions: This study demonstrates the significant impact of LBP on postural control, lumbopelvic control, and functionality. These results highlight the importance of addressing postural and lumbopelvic control in LBP treatment. No significant differences based on gender and age were found, but all clinical variables differed significantly between the LBP and control groups, underscoring the unique impairments associated with LBP.

Measurement Properties of Two Questionnaires Assessing Fear-Avoidance in Patients With Chronic Low Back Pain.

The Fear-Avoidance Components Scale (FACS) and the Fear of Daily Activities Questionnaire (FDAQ) assess fear-avoidance model components. However, the questionnaires are not available in Brazilian Portuguese. This study aimed to translate the original English FACS and FDAQ into Brazilian (Br) Portuguese and assess their measurement properties in patients with Chronic Low Back Pain (CLBP). One hundred thirty volunteers with CLBP participated in this study. Structural validity, internal consistency, test-retest reliability, and hypothesis testing for construct validity were analyzed. Results indicated a 2-factor solution for the FACS-Br, while the FDAQ-Br had a one-factor solution. Internal consistency showed acceptable Cronbach's alpha (alpha >.8). Suitable reliability was found for the FDAQ-Br (Intraclass Correlation Coefficient [ICC] = .98). For both FACS-Br factors, suitable reliability was found as well (ICC = .95 and .94). Hypothesis testing for construct validity confirmed more than 75% of the hypotheses proposed a priori for the FACS maladaptive pain/movement-related beliefs domain and the FDAQ-Br. In conclusion, the FACS-Br and FDAQ-Br demonstrated acceptable reliability, internal consistency, and structural validity measurement properties and their correlation (r < .50) suggests that the tools are not interchangeable measures.

Analysis of Intestinal Bacterial Microbiota in Individuals with and without Chronic Low Back Pain.

Low back pain is a health problem that represents the greatest cause of years lived with disability. This research seeks to evaluate the bacterial composition of the intestinal microbiota of two similar groups: one with chronic low back pain (PG) and the control group (CG). Clinical data from 73 participants and bacterial genome sequencing data from stool samples were analyzed. There were 40 individuals in PG and 33 in CG, aged between 20 and 50 years and with a body mass index of up to 30 kg/m2. Thus, the intragroup alpha diversity and intergroup beta diversity were analyzed. The significant results (p < 0.05) showed greater species richness in PG compared to CG. Additionally, a greater abundance of the species Clostridium difficile in PG was found along with 52 species with significantly different average relative abundances between groups (adjusted p < 0.05), with 36 more abundant species in PG and 16 in CG. We are the first to unveil significant differences in the composition of the intestinal bacterial microbiota of individuals with chronic low back pain who are non-elderly, non-obese and without any other serious chronic diseases. It could be a reference for a possible intestinal bacterial microbiota signature in chronic low back pain.

Prevalence and Risk Factors Associated with Chronic Occupational Low Back Pain among Healthcare Professionals Working at Hospitals: Exploratory Survey Study.

Objective This study aimed to describe the methodological process for developing a questionnaire to identify the prevalence and risk factors for chronic occupational low back pain in healthcare professionals working at hospitals. Method An exploratory crossectional survey study was carried out in Belo Horizonte, MG, Brazil, and its metropolitan region, in two stages. Initially, the authors prepared a questionnaire based on the Roland Morris disability questionnaire and sent it to a committee of low back pain specialists for validation using the Delphi technique. The second stage consisted of sending the final questionnaire to health professionals working in a hospital environment for at least 2 years and presenting chronic low back pain for at least 3 months. Results Validation occurred in two rounds of questionnaire adjustments by a panel consisting of physical therapists and physician experts in the field (orthopedists with more than 3 years of experience). Both rounds had 13 participants. The questionnaire initially consisted of 27 items, and, after validation, it had 19 items. The study included 65 subjects, with an average age of 40.91 years old and an average time working at a hospital of 40 hours per week. The total sample had 76.9% of physicians, 10.8% of physical therapists, and 12.3% of nurses or nursing technicians. Most (52.3%) subjects reported staying in uncomfortable positions affecting the lower back for 5 to 10 hours per day. Conclusion We developed and validated, using the Delphi technique, a questionnaire on the prevalence and risk factors associated with chronic occupational low back pain among healthcare professionals working at hospitals. This unprecedented tool can benefit the population studied since the questionnaires currently used to evaluate chronic low back pain are not specific for investigating the occupational cause of this condition.

[Low back pain and referral to the spine specialist: situation and resources in Buenos Aires]. / Lumbalgia y derivación al especialista de columna: situación y recursos en hospitales públicos de la Ciudad Autónoma de Buenos Aires.

INTRODUCTION: 90% of cases of acute low back pain have no specific underlying cause. International guidelines are available to help identify those individuals who require specialized care. However, in our country, there is a limited emphasis on primary healthcare, with the primary focus on hospital-based care. The aim of this study is to provide an overview of the diagnostic and therapeutic resources utilized in the initial care of patients experiencing low back pain at their first consultation with a specialist physician. METHODS: Descriptive and cross-sectional study, with prospective data collection through a questionnaire administered to patients experiencing low back pain during their first visit to a specialist's office. RESULTS: A total of 44 patients were included, with an average age of 53 years; 50% sought medical attention for chronic pain. Informal referrals were associated with the referring physician's specialty (non-orthopedic), patients with a higher number of emergency department visits, and longer waiting times to obtain the consultation; 52% of patients arrived with at least one complementary study. CONCLUSION: Most of the referrals were appropriate; however, informal referrals were more common. Only 1/5 of the patients underwent an physical examination, and less than 30% of those with red flag symptoms presented with suitable complementary studies. The median waiting time for the consultation was 24 days.

Introducción: El 90% de las lumbalgias agudas son de causa inespecífica. Existen guías internacionales que permiten identificar a aquellos pacientes que requieren atención especializada. En nuestro país la orientación a la atención primaria de la salud es escasa, centrada principalmente en la atención en los hospitales. El objetivo del presente estudio fue describir los recursos de salud, diagnósticos y terapéuticos, utilizados en la atención inicial de pacientes con dolor lumbar que acuden a la consulta del médico especialista Métodos: Estudio descriptivo y transversal, con recolección prospectiva de los datos a través de un cuestionario destinado a pacientes con dolor lumbar que acuden por primera vez a la consulta especializada. Resultados: Se incluyeron 44 pacientes, edad media 53 años; 50% concurrió por dolor crónico. La derivación informal se asoció con: especialidad de derivación (no traumatólogo), pacientes con mayor número de consultas a guardia y mayor demora en obtener la consulta. El 52% concurrió con al menos un estudio complementario. Conclusión: La mayor parte de las derivaciones fueron correctas, sin embargo, predominó la derivación informal. Solo 1/5 de los pacientes fue examinado y menos del 30% de los pacientes con banderas rojas acudió con estudios complementarios adecuados. La mediana del tiempo de espera para la consulta fue 24 días.

One spinal manipulation session reduces local pain sensitivity but does not affect postural stability in individuals with chronic low back pain: a randomised, placebo-controlled trial.

BACKGROUND: Clinical practice guidelines recommend spinal manipulation for patients with low back pain. However, the effects of spinal manipulation have contradictory findings compared to placebo intervention. Therefore, this study investigated the immediate effects of lumbar spinal manipulation on pressure pain threshold (PPT) and postural stability in people with chronic low back pain (cLBP). Second, we investigated the immediate effect of lumbar spinal manipulation on pain intensity and the interference of the participant beliefs about which treatment was received in the PPT, postural stability, and pain intensity. METHODS: A two-arm, randomised, placebo-controlled, double-blind trial was performed. Eighty participants with nonspecific cLPB and a minimum score of 3 on the Numeric Pain Rating Scale received one session of lumbar spinal manipulation (n = 40) or simulated lumbar spinal manipulation (n = 40). Primary outcomes were local and remote PPTs and postural stability. Secondary outcomes were pain intensity and participant's perceived treatment allocation. Between-group mean differences and their 95% confidence intervals (CIs) estimated the treatment effect. One-way analysis of covariance (ANCOVA) was performed to assess whether beliefs about which treatment was received influenced the outcomes. RESULTS: Participants had a mean (SD) age of 34.9 (10.5) years, and 50 (62.5%) were women. Right L5 [between-group mean difference = 0.55 (95%CI 0.19 to 0.90)], left L5 [between-group mean difference = 0.45 (95%CI 0.13 to 0.76)], right L1 [between-group mean difference = 0.41 (95%CI 0.05 to 0.78)], left L1 [between-group mean difference = 0.57 (95%CI 0.15 to 0.99)], left DT [between-group mean difference = 0.35 (95%CI 0.04 to 0.65)], and right LE [between-group mean difference = 0.34 (95%CI 0.08 to 0.60)] showed superior treatment effect in the spinal manipulation group than sham. Neither intervention altered postural stability. Self-reported pain intensity showed clinically significant decreases in both groups after the intervention. A higher proportion of participants in the spinal manipulation group achieved more than two points of pain relief (spinal manipulation = 90%; sham = 60%). The participants' perceived treatment allocation did not affect the outcomes. CONCLUSION: One spinal manipulation session reduces lumbar pain sensitivity but does not affect postural stability compared to a sham session in individuals with cLPB. Self-reported pain intensity lowered in both groups and a higher proportion of participants in the spinal manipulation group reached clinically significant pain relief. The participant's belief in receiving the manipulation did not appear to have influenced the outcomes since the adjusted model revealed similar findings.

Risk of unfavorable pain prognosis impacts walking physiomechanical parameters and psychophysiological workload in sufferers of chronic low back pain.

BACKGROUND: Tolerating physical tasks depends not only on task-specific characteristics but also on an individual's psychophysiological capacity to respond to the imposed load. People suffering from chronic low back pain (CLBP) may experience reduced psychophysiological capacity and are at risk for poor pain prognosis, which could lead to an increased walking workload. AIM: To investigate how the risk of unfavorable pain prognosis in CLBP can impact walking physiomechanical parameters and psychophysiological workload. METHODS: A cross-sectional observational study. The study classified 74 volunteers into four groups based on their prognosis for pain: pain-free control (CG/n = 20), low (LrG/n = 21), medium (MrG/n = 22), and high (HrG/n = 11) risk of poor prognosis for CLBP. The ground assessments identified the self-selected (SSW) and optimal (OWS) walking speeds, as well as the locomotor rehabilitation index (LRI). Treadmill assessments were conducted at two different speeds (0.83 and 1.11 m s-1, SSW and OWS) to record physiomechanical parameters. Psychophysiological workloads during walking were measured via workload impulse for the session (TRIMP), determined by variations in heart rate. RESULTS: CLBP groups exhibited slower SSW and lower LRI compared to the CG. The TRIMP was lower in the LrG. However, both MrG and HrG exhibited a comparable overload to the CG, even while walking at a lower intensity with a psychophysical demand. SSW and OWS displayed an increased TRIMP compared to fixed speeds. CONCLUSION: Psychosocial factors may affect SSW in people with CLBP but not among the risk strata. An unfavorable prognosis for pain could jeopardize the psychophysiological capacity to withstand walking demands.

Embedded motivational interviewing combined with a smartphone application to increase physical activity in people with sub-acute low back pain: a cluster randomised controlled trial.

BACKGROUND: Moderately vigorous physical activity (PA) may be beneficial for people with sub-acute low back pain (LBP), but may initially be painful for patients and challenging for physical therapists to facilitate. OBJECTIVES: This study investigated motivational interviewing (MI) delivered by physical therapists and a smartphone app for increasing PA in people with LBP. METHODS: A mixed methods cluster randomised controlled trial involving 46 adults with LBP in Melbourne, Australia. Participants attended weekly 30-min physical therapy consultations for 6 weeks. Experimental group physical therapists were taught to embed MI into consultations and patients were provided with a self-directed app. The primary outcome was accelerometer-derived moderately vigorous PA. Secondary outcomes were LBP disability (Oswestry Disability Index), functional capacity (Patient Specific Functional Scale), and self-efficacy (Pain Self-Efficacy Questionnaire). Between-group differences were analysed by ANCOVA post-intervention. RESULTS: There was no statistically significant difference between the experimental group and control group for PA. Between-group differences in LBP disability (MD= 19.4 units, 95% CI: 8.5, 30.3), functional capacity (primary MD= -4.1 units, 95% CI: -6.9, -1.3; average MD= -3.1, 95% CI: -4.9, -1.2) and self-efficacy (MD -11.3 units, 95%CI -20.2, -2.5) favoured the control group with small to moderate effect sizes. There were low levels of overall engagement with the app. CONCLUSION: The embedded MI intervention was no more beneficial than physical therapy alone for PA and was associated with poorer LBP disability, function, and self-efficacy. The effectiveness of embedding MI and a smartphone app into usual care for LBP was not supported.

Work bout handling of a search dog reduces handgrip strength and increases firefighters' risk of falls.

OBJECTIVES: Firefighters work with dogs as support for their search activities for victims. Firefighters who handle dogs supposedly have higher acute muscle pain, more stumbling, and fatigue. This study aimed to verify the influence of a mantrailing dog on the firefighter's psychophysiological and muscular responses and the number of imbalances in a simulated activity of searching for people. METHODS: The sample consisted of 10 canine operators characterized by mass (92.57 ± 9.66 kg), height (1.78 ± 0.06 m), age (37.8 ± 2.1 yr), and length of service (9.5 ± 4.6 yr), who performed a search activity under 2 experimental conditions (dog condition and control condition). The simulated search activity consisted of a predefined hike of 2.5 km between the beginning of a search and the place where the sham victim was hidden. Cardiometabolic variables, pain level, and muscular performance were measured pre and postactivity (time factor). The number of imbalances suffered during hiking was also quantified. RESULTS: ANOVA data indicated interactions (condition × time) related to handgrip strength (P < 0.05). Handgrip strength was reduced in the postsearch activity with the dog, and it increased the control when compared to the preactivity (-12.3% versus +9.2%). Also, the level of pain and discomfort in the neck, trunk, and hip regions was higher with dogs (P < 0.05). Under the dog and control conditions, there were 25 and 05 imbalances, respectively, during the hike. There were no significant differences between the experimental conditions for vertical jump performance and cardiovascular responses either with dog or control. CONCLUSIONS: The findings of this study highlight that a mantrailing dog with the firefighter increased the number of slips, trips, sudden changes in direction, and loss of body balance, accompanied by a reduction in handgrip strength, and increased acute pain in the neck, trunk, and hip. These findings may contribute to support strategies for mitigating injuries and optimizing the performance of canine operators in the fire department and other units cinotechnic.

Effectiveness of in-group versus individually administered pain neuroscience education on clinical and psychosocial outcomes in patients with chronic low back pain: randomized controlled study protocol.

Objective: (1) This trial will compare the clinical and psychosocial effectiveness of in-group and individually pain neuroscience education (PNE) in patients with chronic low back pain (CLBP). In addition, (2) the influence of social determinants of health on post-treatment results will be analyzed. Methods: A three-arm randomized controlled trial will be conducted. Sixty-nine participants with CLBP will be recruited in a 1:1:1 ratio. Participants, assessor, and statistician will be blinded to group assignment. The PNE intervention will be adapted to the context of the participants. An experimental group (n = 33) will receive PNE in an in-group modality, the other experimental group (n = 33) will receive PNE in an individually modality and the control group (n = 33) will continue with usual care. Additionally, participants will be encouraged to stay active by walking for 20-30 min 3-5 times per week and will be taught an exercise to improve transversus abdominis activation (bracing or abdominal following). The outcome measures will be fear avoidance and beliefs, pressure pain threshold, pain self-efficacy, catastrophizing, pain intensity, and treatment expectation. Outcome measures will be collected at one-week before intervention, immediately post-intervention, and four-weeks post-intervention. Conclusion: The innovative approach of PNE oriented to fear beliefs proposed in this study could broaden the application strategies of this educational therapeutic modality. Impact. Contextualized PNE delivered by physical therapist could be essential to achieve a good cost-effectiveness ratio of this intervention to improve the clinical condition of people with CLBP.

What are the costs of managing neck and low back pain in Brazil? Investigation of a ten-year period from the perspective of the Brazilian public health system.

INTRODUCTION: Considering the prospects of increased prevalence and disability due to neck and low back pain, it is relevant to investigate the care processes adopted, to assist future public policies and decision-making for a better allocation of resources. Objective: the aim of this study was to estimate the costs arising from inpatient and outpatient care of individuals with Neck Pain (NP) and Low Back Pain (LBP) in Brazil, between 2010 and 2019. METHODS: This is a cost-of-illness study from the perspective of the Brazilian public health system, based on health conditions with high prevalence (neck and low back pain). Data were presented descriptively using absolute and relative values. RESULTS: Between 2010 and 2019, the health system spent more than $600 million (R$ 2.3 billion) to treat NP and LBP in adults, and LBP accounted for most of the expenses. Female had higher absolute expenses in inpatient care and in the outpatient system. CONCLUSION: Our study showed that the costs with NP and LBP in Brazil were considerable. Female patients had higher outpatient costs and male patients had higher hospitalization costs. Healthcare expenses were concentrated for individuals between 34 and 63 years of age.

This study focused on understanding how much it cost to treat neck pain (NP) and low back pain (LBP) in Brazil between 2010 and 2019, from the point of view of the public health system (i.e. Unified Health System ­ SUS). The idea was to find out how much money was spent and where. It turned out that the SUS spent, in total, more than US$600 million (R$2.3 billion) with LBP responsible for most of these expenses. Furthermore, we noted that women had higher outpatient care costs, while men had higher hospitalization costs. Those costs were more concentrated in people aged between 34 and 63 years.

Hip biomechanics in patients with low back pain, what do we know? A systematic review.

BACKGROUND: Biomechanical alterations in patients with low back pain (LBP), as reduced range of motion or strength, do not appear to be exclusively related to the trunk. Thus, studies have investigated biomechanical changes in the hip, due to the proximity of this joint to the low back region. However, the relationship between hip biomechanical changes in patients with LBP is still controversial and needs to be summarized. Therefore, the aim of this study was to systematically review observational studies that used biomechanical assessments in patients with non-specific LBP. METHODS: The search for observational studies that evaluated hip biomechanical variables (i.e., range of motion, kinematic, strength, and electromyography) in adults with non-specific acute, subacute, and chronic LBP was performed in the PubMed, Embase, Cinahl and Sportdiscus databases on February 22nd, 2024. Four blocks of descriptors were used: 1) type of study, 2) LBP, 3) hip and 4) biomechanical assessment. Two independent assessors selected eligible studies and extracted the following data: author, year of publication, country, study objective, participant characteristics, outcomes, and results. The methodological quality of the studies was assessed using the Epidemiological Appraisal Instrument and classified as low, moderate, and high. Due to the heterogeneity of the biomechanical assessment and, consequently, of the results among eligible studies, a descriptive analysis was performed. RESULTS: The search strategy returned 338 articles of which 54 were included: nine articles evaluating range of motion, 16 evaluating kinematic, four strength, seven electromyography and 18 evaluating more than one outcome. The studies presented moderate and high methodological quality. Patients with LBP, regardless of symptoms, showed a significant reduction in hip range of motion, especially hip internal rotation, reduction in the time to perform functional activities such as sit-to-stance-to-sit, sit-to-stand or walking, greater activation of the hamstrings and gluteus maximus muscles and weakness of the hip abductor and extensor muscles during specific tests and functional activities compared to healthy individuals. CONCLUSION: Patients with LBP present changes in range of motion, task execution, activation, and hip muscle strength when compared to healthy individuals. Therefore, clinicians must pay greater attention to the assessment and management of the hip during the treatment of these patients.

Comparison of aquatic physiotherapy and therapeutic exercise in patients with chronic low back pain.

OBJECTIVE: To investigate and compare the effectiveness of aquatic physiotherapy and therapeutic exercise in the physical and functional performance of patients with chronic low back pain. METHODS: Twenty-six participants were randomized into 3 groups, namely an aquatic physiotherapy group (AG), a therapeutic exercise group (EG), and a control group (CG). The pain, disability, and quality of life were compared before and after the exercise protocols for 2 months, twice a week, on alternate days, for 60 min. For statistical analyses, the Kruskal-Wallis test was used to test the difference between the groups; the Wilcoxon test and the effect size were used for before-and-after comparisons. RESULTS: Twenty participants completed the study. There was a significant difference improvement in pain between the AG and the EG (p = 0.004), between the EG and the CG (p = 0.05), and in social role functioning between the groups (p = 0.02). No differences were observed in the other analyzed variables between the groups. Compared to the pre-treatment state, there were significant improvements in the AG in terms of pain (p = 0.02), functionality (p = 0.03), and general health status (p = 0.04). CONCLUSION: The AG group showed significant and clinical improvement in pain, disability, and quality of life. Improvements related to social aspects were found in the EG compared to the CG. The water provides a safe environment that facilitates the onset of exercise, so aquatic physiotherapy could be considered the first recommendation for patients with low back pain.

Clinical indicators to monitor health care in low back pain: a scoping review.

Clinical care indicators for low back pain can be used to monitor healthcare practices and consequently be used to evaluate success of strategies to improve care quality. The aim of this study was to identify the clinical care indicators that have been used to measure appropriateness of health care for patients with low back pain. We conducted a systematic search of five electronic databases and Google to identify clinical care indicators that have been used to measure any aspect of care for people with low back pain. Care indicators were narratively described according to their type (i.e. structure, process, or outcomes) and categorized by their purpose (e.g. to measure aspects related to assessment, imaging requests, treatment/prevention, and outcomes). A total of 3562 and 2180 records were retrieved from electronic databases and Google searches, respectively. We identified 280 indicators related to low back pain care from 40 documents and publications. Most quality indicators were process indicators (n = 213, 76%), followed by structure (n = 41, 15%) and outcome indicators (n = 26, 9%). The most common indicators were related to imaging requests (n = 41, 15%), referral to healthcare providers (n = 30, 11%), and shared decision-making (n = 21, 7%). Our review identified a range of clinical care indicators that have been used to measure the quality of health care for people with low back pain. Our findings will support a Delphi study to reach international consensus on what would be the most important and feasible indicators for a minimum dataset to be collected globally.

Immediate effect of extracorporeal shockwave therapy in patients with chronic non-specific low back pain: A randomised placebo-controlled triple-blind trial.

OBJECTIVE: To compare the immediate effects of shockwave therapy using two different tips in patients with chronic non-specific low back pain. DESIGN: Randomised placebo-controlled study with three intervention groups. SETTING: The patients recruited for this study were sent for physiotherapy treatment at primary care between May and July 2022. PARTICIPANTS: Eighty-one patients with chronic non-specific low back pain aged 18-80 years with pain for ≥3 months and pain intensity ≥3 were randomly recruited for the study. INTERVENTION: The patients received a single intervention of radial shockwave therapy with 2000 discharges at 100 mJ energy and 5 Hz frequency using concave or convex tips or placebo treatment. MAIN MEASURES: The primary outcome was pain intensity immediately post-intervention. The secondary outcomes were pressure pain threshold, temporal summation of pain, and functional performance. Data were collected at baseline and post-intervention. RESULTS: The post-intervention pain intensity in the concave tip group is an average of two points lower (95% CI = -3.6, -0.4; p < 0.01) than that in the placebo group. The post-intervention pressure pain threshold for the concave tip group was an average of 62.8 kPa higher (95% CI = 0.4, 125.1; p < 0.05) than for the convex tip group and 76.4 kPa higher (95% CI = 14, 138.7; p < 0.01) than in the placebo group. CONCLUSION: The concave tip shockwave therapy is effective in reducing pain and local hyperalgesia in patients with chronic non-specific low back pain.

Treatment Options for Failed Back Surgery Syndrome: An Umbrella Systematic Review of Systematic Reviews on the Effectiveness of Therapeutic Interventions.

Background: Failed back surgery syndrome (FBSS) is a common and incapacitating condition affecting patients with previous spine surgery in whom treatment approach can be challenging. This study aimed to summarize existing secondary studies and up-to-date randomized clinical trials (RCTs) that assess the effectiveness of available treatment options for FBSS. Methods: Systematic searches were carried out in five databases (PubMed, Cochrane, Scielo, Epistemonikos, and Google scholar) for all systematic reviews on the effectiveness of treatment options for FBSS published after 2012. Outcomes of interest were pain levels measured through visual analog scale or numeric rating scale, Oswestry Disability Index, and quality of life. Methodological and risk of bias assessments were performed with the AMSTAR-2 tool for systematic reviews and the Joanna Briggs Institute checklist for RCT. Prospective PROSPERO registration: CRD42022307609. Results: Fifteen studies, seven systematic reviews, and eight RCTs met the inclusion criteria and fulfilled the methodological quality assessment. Of the 15 included studies, 8 were on neurostimulation, 4 on adhesiolysis, 4 on epidural or intrathecal injections, and 3 on other treatment modalities. The risk of bias was low in seven studies, moderate in five, and high in three. Conclusions: Based on this systematic overview and the considerable heterogeneity among studies, the FBSS therapeutic approach must be individualized. FBSS treatment should start with conservative management, considering the implementation of neurostimulation, a technique with the most robust evidence of effective results, in cases of refractory axial or neuropathic pain. As the last resource, in light of the evidence found, more invasive procedures or new surgical interventions are indicated.

Efectividad de la acupuntura para el alivio del dolor lumbar en el cuerpo de guardia

Introducción: La lumbalgia se presenta en aproximadamente 9,4 % de la población mundial.

Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica (sin grupo control) en 35 pacientes con dolor lumbar, los cuales fueron atendidos en el Cuerpo de Guardia de Medicina Natural y Tradicional del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, desde julio hasta diciembre del 2021. Resultados: En la investigación primaron el grupo etario de 40-49 años (31,4 %), el sexo femenino (57,1 %), las amas de casa, el dolor entre grave y moderado al inicio del tratamiento, así como los pacientes sin dolor una hora después de la terapia. En cuanto a la evolución final, el total de la muestra clasificó en las categorías de aliviados y mejorados. Conclusiones: Se demostró la efectividad de la acupuntura en pacientes con dolor lumbar agudo.

Introduction: Low back pain is presented in approximately 9.4% of the world population. Acupuncture is used by Chinese traditional medicine to stimulate certain points of the body with different types of needles. Among its beneficial effects the pain remission is described. Objective: To evaluate the effectiveness of the acupuntural treatment in patients with lumbar pain assisted in the emergency room. Methods: A quasi-experiment of therapeutic intervention study (without control group) was carried out in 35 patients with lumbar pain, who were assisted in the Natural and Traditional Medicine Emergency Room of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from July to December, 2021. Results: In the investigation there was a prevalence the 40-49 age group (31.4%), female sex (57.1%), housewives, serious and moderate pain at the beginning of the treatment, as well as patients without pain one hour after the therapy. As for the final clinical course, the total of the sample classified in the relieved and improved categories. Conclusions: The effectiveness of acupuncture was demonstrated in patients with acute lumbar pain.

Pielonefritis aguda izquierda en paciente con lumbalgia bilateral y duplicidad ureteral: Caso clínico / Acute left pyelonephritis in patient with bilateral low back pain and ureteral duplicity: Case report

RESUMEN El caso es de una mujer de 46 años con pielonefritis aguda izquierda y duplicidad ureteral bilateral. La pielonefritis aguda es una infección grave del tracto urinario que puede variar en su presentación clínica, desde síntomas leves hasta sepsis. El dolor lumbar es un síntoma común en la pielonefritis aguda, y puede presentarse de forma unilateral o bilateral. La duplicidad ureteral es una anomalía congénita que resulta en uréteres que transportan la orina desde el mismo riñón hasta la vejiga, y puede causar complicaciones como reflujo vesicoureteral y obstrucción ureteral. El tratamiento incluyó antibióticos y control ambulatorio en consulta de Urología. El caso destaca la importancia de un enfoque diagnóstico meticuloso y la consideración de anomalías congénitas subyacentes que pueden complicar el cuadro clínico y el tratamiento. La integración de hallazgos clínicos, análisis de laboratorio y pruebas de imagen fue fundamental para el diagnóstico preciso y el plan de tratamiento adecuado.

ABSTRACT The case presents a 46-year-old woman with left acute pyelonephritis and bilateral duplicated ureters. Acute pyelonephritis is a severe urinary tract infection that can vary in clinical presentation, from mild symptoms to sepsis. Lower back pain is a common symptom and can be unilateral or bilateral. Duplicated ureters are a congenital anomaly resulting in the transport of urine from the same kidney to the bladder, and can cause complications such as vesicoureteral reflux and ureteral obstruction. Treatment involved antibiotics and outpatient urology follow-up. The case underscores the importance of a meticulous diagnostic approach and consideration of underlying congenital anomalies that can complicate clinical management and treatment. The integration of clinical findings and complementary tests was essential for an accurate diagnosis and appropriate treatment plan.
