RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Abstract 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.

Resumo Objetivo Este estudo pretende descrever o processo metodológico para a elaboração de um questionário para identificar a prevalência e os fatores de risco associados à dor lombar ocupacional crônica nos profissionais da área da saúde que atuam em nível hospitalar. Método Foi realizado um estudo transversal exploratório do tipo questionário. O estudo foi realizado na cidade de Belo Horizonte e região metropolitana, em duas etapas. Inicialmente foi elaborado pelos autores um questionário baseado no questionário de deficiências Roland Morris e enviado a um comitê de especialistas em lombalgia para validação do mesmo através da técnica Delphi. A segunda etapa consistiu em enviar o questionário final a profissionais de saúde que atuam em ambiente hospitalar há pelo menos 2 anos e que tenham lombalgia crônica há pelo menos 3 meses. Resultados A validação foi realizada em duas rodadas de adequações do questionário, com painel composto por fisioterapeutas e médicos especialistas na área (ortopedistas com mais de 3 anos de atuação). Ambas as rodadas contaram com 13 participantes. O questionário foi composto inicialmente por 27 itens e, após validação, 19 itens. O estudo incluiu 65 indivíduos, com idade média de 40,91 anos e tempo médio de atuação em nível hospitalar semanal de 40 horas. A amostra total possuía 76,9% médicos, 10,8% fisioterapeutas e 12,3% enfermeiros ou técnicos de enfermagem. A maioria (52,3%) dos indivíduos relatou manter-se em posições desconfortáveis que afetam a região lombar por 5 a 10 horas por dia. Conclusão Foi desenvolvido e validado, pela técnica Delphi, um questionário sobre a prevalência e fatores de risco associados a dor lombar ocupacional crônica entre profissionais da área da saúde que atuam em nível hospitalar. Este instrumento inédito pode trazer benefícios para a população estudada, visto que os questionários utilizados atualmente para a avaliação de dor lombar crônica não são específicos para a investigação da causa ocupacional de tal condição.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
