Evaluation of the psychometric properties of the health care providers' pain and impairment relationship scale (HC-PAIRS) in health professionals and university students from Chile and Colombia.

Background: Chronic back pain is a frequent and disabling health problem. There is evidence that ignorance and erroneous beliefs about chronic low back pain among health professionals interfere in the treatment of people who suffer from it. The Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) has been one of the most used scale to assess these misbeliefs, but no studies have been reported in Latin America. Method: We studied the factorial structure of the HC-PAIRS in health personnel and health sciences university students in two Latin American countries: Colombia (n = 930) and Chile (n = 190). Spain's data was taken of the original study of the Spanish version of the HC-PAIRS (171 Physiotherapy students). Additionally, the measurement invariance of this scale among Chile, Colombia and Spain was evaluated by calculating three nested models: configural, metric and scalar. We used a Confirmatory Factor Analysis (CFA) in both Latin American samples, with Maximum Likelihood Robust (MLR) estimation to estimate the parameters. For the final model in each sample, reliability was assessed with the Composite Reliability (CR) index, and to obtain the proportion of variance explained by the scale the Average Variance Extracted (AVE) was calculated. Results: The one-factor solution shows an acceptable fit in both countries after deleting items 1, 6, and 14. For the resulting scale, the CR value is adequate, but the AVE is low. There is scalar invariance between Chile and Colombia, but not between these two countries and Spain. Conclusions: HC-PAIRS is useful for detecting misconceptions about the relationship between chronic low back pain that would cause health personnel to give wrong recommendations to patients. However, it has psychometric weaknesses, and it is advisable to obtain other evidence of validity.

Understanding the Landscape of Spinal Injections: Insights and Challenges from Latin America.

BACKGROUND: Low back pain and neck pain are primary causes of disability, with low back pain being a frequent reason for medical consultations. After conservative and pharmacological treatments, spinal injections are considered the next option. Despite multiple guidelines, spinal blocks remain controversial in terms of indication, technique, and operator, leading to considerable interinstitutional variability. The absence of regional studies in Latin America on how spinal surgeons handle spinal injections prompts the objectives of this study: to evaluate spinal surgeons' knowledge and experience, analyze techniques, and identify barriers and challenges in implementing spinal injections, including resource limitations, technology access, and training. METHODS: A cross-sectional survey was performed using a questionnaire specifically designed by the authors. RESULTS: Two hundred sixty spinal surgeons from Latin America participated and answered a 17-question questionnaire; 75% performed their own spinal blocks and they are willing to keep on learning new techniques on the field. The most frequent block, was the lumbar facet injection (80%). And the great majority (76%) used fluoroscopy in their practice. CONCLUSIONS: The study addresses a critical gap in the literature by focusing on spinal interventions in Latin America, where there is a notable lack of regional studies. The majority of the surgeons enrolled perform their own spinal injections, and they are interested in keep on learning. The findings not only contribute to the global discourse on spinal care but also offer a basis for the development of region-specific guidelines and educational initiatives.

Self-Reported Chronic Back Pain and Current Depression in Brazil: A National Level Study.

There is limited literature investigating the association between chronic back pain (CBP) and depression in Brazil. This study evaluates the association between CBP, CBP-related physical limitations (CBP-RPL), and self-reported current depression (SRCD), in a nationally representative sample of Brazilian adults. The data for this cross-sectional study came from the 2019 Brazilian National Health Survey (n = 71,535). The Personal Health Questionnaire depression scale (PHQ-8) was used to measure the SRCD outcome. The exposures of interest were self-reported CBP and CBP-RPL (none, slight, moderate, and high limitation). Multivariable weighted and adjusted logistic regression models were used to investigate these associations. The weighted prevalence of SRCD among CBP was 39.5%. There was a significant weighted and adjusted association between CBP and SRCD (weighted and adjusted odds ratio (WAOR) 2.69 (95% CI: 2.45-2.94). The WAOR of SRCD among individuals with high, moderate, and slight levels of physical limitation was significantly greater than for those without physical limitation due to CBP. Among Brazilian adults with high levels of CBP-RPL, there was over a five-fold increased risk of SRCD compared to those without CBP-RPL. These results are important for increasing awareness of the link between CBP and SRCD and for informing health services policies.

Predictors for physical activity and its change after active physical therapy in people with spinal pain and insomnia: Secondary analysis of a randomized controlled trial.

BACKGROUND: In healthy people and people with nonspecific chronic spinal pain (nCSP) and/or insomnia, participation in physical activity on a regular basis has several physical and psychological health benefits. However, people with chronic conditions often tend to reduce physical activity participation which can lead to deconditioning over time. Currently, there are no known predictors for an (in)active lifestyle (before and after physical therapy treatment) in people with chronic spinal pain and comorbid insomnia. OBJECTIVE: To examine predictors of pre-treatment moderate-to-vigorous physical activity (MVPA) and to examine determinants for a change in MVPA in response to 14-weeks of active physical therapy treatment in people with nonspecific chronic spinal pain (nCSP) and comorbid insomnia. METHODS: Baseline data and post-treatment data were analyzed for 66 participants. A linear multiple regression analysis was conducted to examine which factors predict MVPA at baseline. Linear mixed-effects modeling was used to identify determinants for change in MVPA in response to an active physical therapy treatment. RESULTS: Physical fatigue (b = -0.9; 95%CI: -1.59, -0.15), less limitations in functioning as a result of emotional problems (b = 0.1; 95%CI: 0.03, 0.10), mental fatigue (b = -1.0; 95%CI: -1.67, -0.43), lower general sleep quality (b= 0.7; 95%CI: 0.22, 1.17), and body mass index (b = -0.5; 95%CI: -0.93, -0.16) were significant predictors of baseline MVPA. The regression model explained 33.3% of the total variance in baseline MVPA. The change of MVPA in response to the treatment ranged from a decrease of 17.5 to an increase of 16.6 hours per week. No determinants for change in MVPA after treatment could be identified. CONCLUSION: People with nCSP and comorbid insomnia are more likely to engage in MVPA if they report, at baseline, lower sleep quality, fewer limitations in functioning resulting from emotional problems, lower body mass index, as well as less physical and mental fatigue.

Effect of low back pain on clinical-functional factors and its associated potential risk of chronicity in adolescent dancers of classical ballet: cross-sectional study.

BACKGROUND: Low back pain (LBP) is a common symptom in classical ballet dancers, which can limit their daily activities and dance training routines. The purpose of the study was to verify the association and comparison of clinical-functional outcomes (spine flexibility and foot posture) between different levels of intensity low back pain in adolescents of classical ballet and the potential risk of chronicity using the STarT back tool. METHODS: Cross-sectional study. PARTICIPANTS: 78 adolescent girls who practice classical ballet were evaluated and divided into groups according to level of low back pain: mild (n = 21), moderate (n = 17), and high (n = 20), and a control group (n = 20). MAIN OUTCOME MEASURES: Pain, flexibility of the spine (thoracic and lumbosacral), risk of chronicity for low back pain, and foot posture were assessed using the visual analogue scale, clinical tests, STarT back screening tool (SBST) questionnaire, and foot posture index (FPI), respectively. RESULTS: Dancers with high-intensity low back pain showed a potential risk of chronicity by the SBST. The spine pain intensity was not different considering thoracic and lumbosacral flexibility in the sagittal plane, but was different with greater supine FPI when compared to control dancers. Mild low back pain was associated with greater supine FPI. The SBST score was associated with higher exposure time-frequency and time of dancing. CONCLUSION: Adolescents of classical ballet with high-intensity low back pain showed a potential risk of chronicity by the SBST. The level of intensity low back pain did not influence the clinical-functional aspects of spine flexibility in the sagittal plane, but the level of intensity moderate pain promoted changes in foot posture (more supinated). The potential risk of chronicity using the SBST was also associated with higher exposure time-frequency and time of dancing, in adolescents of classical ballet.

Prevalência e fatores associados a problema crônico de coluna em mulheres em idade fértil / Prevalence and factors associated with chronic back problem in women of childbearing age

Resumo No Brasil, dados da Pesquisa Nacional de Saúde (PNS) estimaram 27,0 milhões de pessoas (18,5%) que referiram Problema Crônico de Coluna (PCC), afetando mais mulheres que homens. Este trabalho tem o objetivo de identificar, entre as mulheres em idade fértil, os fatores associados ao PCC. Trata-se de um estudo transversal realizado com dados da PNS, em que a variável dependente foi a prevalência de PCC, enquanto que os fatores associados incluíram itens sociodemográficos, hábitos de vida, histórico reprodutivo, estado nutricional, diagnóstico de depressão e percepção de saúde. Foram avaliadas 22.621 mulheres com idade entre 18 e 49 anos e, destas, 14,8% referiram ter PCC. Os fatores de risco estudados foram: aumento da faixa etária; viver com cônjuge/companheiro; multiparidade; ser tabagista; sobrepeso ou obesidade, ter Circunferência da Cintura (CC) acima de 80cm e índice Circunferência/Estatura (C/E) acima de 0,5; autopercepção de saúde negativa; e diagnóstico de depressão. O único fator de proteção encontrado foi escolaridade. As associações observadas concluem que idade, viver com cônjuge/companheiro, tabagismo, multiparidade, sobrepeso e obesidade, risco aumentado para doenças cardiovasculares, diagnóstico de depressão e autopercepção de saúde negativa estão associados ao desenvolvimento de PCC em mulheres de idade fértil.

Abstract Chronic Back Problem (CBP) is a public health concern. In Brazil, data from the National Health Survey (PNS) estimated 27.0 million people (18.5%) who reported CBP, affecting more women than men. This study aims to identify the factors associated with CBP among women of childbearing age. It is a cross-sectional study carried out with data from the PNS, where the dependent variable was the prevalence of CBP, and associated factors included socio-demographic items, life habits, reproductive history, nutritional status, diagnosis of depression and health perception. A total of 22,621 women aged 18 to 49 years were interviewed. Of these, 14.8% reported having CBP. The risk factors studied were: increased age; living with spouse; multiparity; smoking; overweight or obese, having Waist Circumference (WC) above 80cm and Circumference/Height (C/E) index above 0.5; negative self-perception of health; and depression. The only protective factor associated with CBP risk reduction was education level. We conclude that age, living with a spouse/partner, smoking, multiparity, being overweight or obese, increased risk for cardiovascular diseases, depression and negative self-perceived health are associated with the development of CBP in women of childbearing age.

[Validation of the Oswestry disability scale for low back pain in patients with chronic back pain. Cienfuegos, 2017-2018]. / Validación de la escala de incapacidad por dolor lumbar de Oswestry, en paciente con dolor crónico de la espalda. Cienfuegos, 2017-2018.

INTRODUCTION: A large number of patients have chronic back pain, producing disability. Consequently, there is a need to validate instruments for pain measurement. The aim of this study was to determine the validity and reliability of the Oswestry Disability Scale for Low Back Pain in the population with chronic back pain in Cienfuegos. MATERIAL AND METHOD: The investigation consisted of the development of an instrument to validate the scale through content validity, construct validity and reliability analysis. The validation included linguistic and cultural adaptation of the instrument. The study was conducted at the Dr. Gustavo Aldereguía Lima University Hospital in Cienfuegos, Cuba, from September 2017 to October 2018. Systematic randomised sampling was used. The sample included 162 patients. The statistical analysis was performed with the SPSS statistical package. RESULTS: The experts considered that the instrument should remain unchanged. Factorial analysis identified the presence of three intercorrelated factors that represented 63% of the total. A global Cronbach α of 0.801 was obtained and the temporal stability of the instrument was demonstrated. CONCLUSIONS: The results confirm the validity and reliability of the Oswestry Disability Scale for Low Back Pain in the Cienfuegan population with chronic back pain.

Evaluación del catastrofismo en pacientes con lumbalgia crónica en la unidad de dolor de un hospital universitario / Evaluation of pain catastrophizing in chronic back pain patientsof a university hospital pain unit

El catastrofismo es la percepción mental, negativa y exagerada, respecto a la experiencia del dolor, tanto real como anticipada. Comprende tres dimensiones: rumiación, magnificación y desesperanza. Sus consecuencias son: dolor más intenso, mayor consumo de analgésicos, disminución de las actividades diarias, incapacidad laboral, mayor sensibilidad al dolor, interferencia en el uso de estrategias de afrontamiento y peor pronóstico general. El objetivo de este estudio fue evaluar el nivel de catastrofismo ante el dolor en pacientes con lumbalgia crónica que consultan en nuestro hospital universitario, utilizando la escala de catastrofismo del dolor en su versión en español. La muestra fue de 69 pacientes, se encontró una correlación lineal positiva entre nivel total de catastrofismo y sus tres dimensiones con la intensidad del dolor y la interferencia que éste produce sobre las actividades diarias, medidas a través del inventario abreviado del dolor. Los niveles de catastrofismo encontrados fueron altos, mayores a 30, la intensidad del dolor y su interferencia fueron elevados (mayor de 6). Este es el primer estudio de evaluación del catastrofismo en pacientes con dolor crónico en nuestro país. Los niveles de catastrofismo encontrados obligan a ofrecer en nuestra unidad medidas de intervención que logren reducirlo, de modo de lograr mejores resultados de los tratamientos farmacológicos o intervencionistas que se indican en los pacientes con lumbalgia crónica.

Pain catastrophizing is a cognitive state characterized by a negative and exaggerated perception about actual or anticipating pain. It is conformed for three factors: rumiation, magnification and helplessness. Its consequences in pain perception are increase in pain intensity and analgesic consumption, interference in daily and labor activities, hiperalgesia, interference in coping strategies and general poor clinical prognosis of pain states. The aim of this study was to evaluate pain catastrophizing in chronic back pain outpatients in a university hospital pain unit, utilizing the spanish version of the pain catastrophizing scale. Sixty-nine patients with chronic back pain with or without lumbosacral radicular pain were included. A positive lineal correlation between total catastrophism and its three factors with pain intensity and pain daily activities interference. Pain intensity and interference evaluated by the brief pain Inventory were high (more than 6) and also was the total catastrophism (more than 30). This is the first study in our country about pain catastrophizing in chronic pain patients. The high levels of catastrophism observed in this study must be treated with specific psychological interventions, in order to reduce them in such a way that pharmacological and interventional pain treatments results could be improved.

Programa de rehabilitación integral en pacientes con dolor cronico de espalda: un estudio de caso / Rehabilitation program in patients with chronic back pain: a case study

La utilización de estrategias combinadas para el manejo de pacientes con dolor crónico, ha demos-trado eficacia en su recuperación. Este trabajo tiene como objetivo mostrar la aplicación de abor-dajes psicológicos y fisioterapéuticos en la rehabilitación de un paciente masculino de 62 años con dolor crónico de espalda. Las estrategias fisioterapéuticas aplicadas se basaron en la aplicación de técnicas Tens, Ultrasonido, ejercicios de balonterapia, ejercicios isométricos e isotónicos, medios físicos, técnica de Mckenzy y ejercicios de cadenas cinética, las cuales se suministraron con una duración de 1 hora por cada sesión diaria, durante un periodo de 15 días y el efecto del tratamien-to aplicado se evaluó mediante la valoración de problemas osteomusculares (OM). El tratamiento psicológico de acompañamiento se basó en un entrenamiento cognitivo conductual (ECC) sumi-nistrado con una periodicidad semanal; el nivel de mejora de vida del paciente fue medido con la escala de ansiedad Hamilton, y el cuestionario de estrategias de afrontamiento (CIQ) y Euro-gol. Las valoraciones fisioterapéuticas se aplicaron antes, durante y después del tratamiento, mientras que las valoraciones psicológicas se aplicaron antes y después, y demostraron una rehabilitación integral eficiente; disminuyendo el dolor crónico de espalda, aumentando la movilidad y mejoran-do la calidad de vida al disminuir los índices de dolor a la palpación y al movimiento, medida en escala numérica de Borg. Igualmente se observó disminución en el índice de discapacidad lumbar de Oswestry, disminución en los niveles de ansiedad y recuperación total del paciente lo que de-muestra que la rehabilitación integral del paciente fue eficaz.

The use of combined strategies for the management of patients with chronic pain has shown effectiveness in recovery, so this work shows the application of psychological approaches and physiotherapy in the rehabilitation of a 62 year old male patient with chronic back pain. The applied physiotherapy strategies were based on the application of techniques such as Tens, Ul-trasound, balloon-therapy exercises, isometric and isotonic exercises, physical mediums, the McKenzy technique and kinetic chain exercises, which were provided as one hour long daily session, for a period of 15 days and the effect of the applied treatment was evaluated by assessing musculoskeletal problems (OM). The accompanying psychological treatment was based on a cognitive behavioral training (ECC) that was performed weekly; the level of life improvement of the patients was measured with the Hamilton anxiety scale, the coping strategies questionnaire (CIQ) and Euro-gol. The physiotherapy assessments were applied before, during and after the treatment, while psychological assessments were applied before and after and showed an efficient complete rehabilitation, reducing chronic back pain, increasing mobility and improving quality of life by reducing the indexes of tenderness to pain and movement, with the Borg numerical scale. Furthermore, it was observed that the lumbar disability index of Oswestry also decreased, as well as the anxiety levels and there was a total patient recovery demonstrating that comprehen-sive patient rehabilitation was effective.

Eficacia del bloqueo facetario en pacientes con síndrome facetario lumbar / Efficacy of facet block in patients with lumbar facet joint syndrome

El bloqueo facetario es un procedimiento usado en aquellos pacientes con artrosis facetaria en los cuales han fallado los múltiples tratamientos médicos. En nuestro país se desconocen estudios o estadísticas que demuestren su efectividad, por lo que se consideró pertinente demostrarlo. Se realizó un estudio observacional retrospectivo de una cohorte de pacientes intervenidos en el período comprendido entre enero de 2005 y diciembre de 2009 en la Clínica CES. Se recolectó información de las historias clínicas mediante un formulario diseñado para tal fin; además se relacionó la existencia de mejoría del paciente posterior a la intervención con edad, sexo, ocupación, tiempo de evolución, síntomas motores y sensitivos previos y enfermedades asociadas. La población fue de 232 pacientes entre 21 y 92 años, con una edad promedio de 56,9 (± 14,6) años, con un tiempo de evolución del dolor lumbar de 2 años en el 40% de la población estudiada. La resonancia magnética fue el estudio más utilizado previo al procedimiento en 42,2% de los pacientes, la tomografía en 38,31% y los rayos X en 7,46%. El procedimiento fue eficaz en el 78% de los pacientes. En conclusión, el bloqueo facetario es un método terapéutico, ya que se vio mejoría de la sintomatología en la mayoría de los pacientes estudiados. Esto es coherente con otros estudios realizados, donde también se ha evidenciado disminución de las limitaciones físicas y funcionales de los pacientes. Además, es un procedimiento diagnóstico ya que la mejoría con esta técnica indica que la patología sí era facetaria.

Facet block is a procedure used in patients with facet arthrosis in which several other medical techniques have failed. In our country, there is no evidence or studies regarding its efficacy, thus the interest in its demonstration. A retrospective observational cohort study was carried out on patients intervened between January 2005 and December 2009 at Clínica CES. Data was collected from the patient's clinical records by means of a survey designed for that purpose. Also, positive clinical outcomes were correlated to age, gender, occupation, evolution time, motor and sensitive symptoms as well as comorbidities. The sample included 232 patients between the ages of 21 and 92, with an average age of 56.9 (± 14.6) years, and a lumbar pain evolution time of 2 years in 40% of the individuals in the sample. The most commonly used imaging test before the procedure was magnetic resonance imaging in 42.2% of patients, computed tomography scan was used in 38.31% and X-rays in 7.46%. The procedure was effective in 78% of patients. In sum, facet block is a therapeutic method, given that most patients improved after its completion. These findings are consistent with other studies that have showed a decrease in physical and functional limitations of the patients. Besides, improvement of the patient's state confirms a lumbar facet syndrome, so it is a diagnostic procedure as well.
