ABSTRACT
Introducción: El dolor lumbar crónico en los universitarios oscila entre un 12,4 y 75 %. Se evidenció inicialmente que la alteración de la musculatura del recto abdominal puede estar asociada al dolor lumbar. Objetivo: Evaluar la asociación entre la distancia de los bordes mediales del músculo recto abdominal y la presencia de dolor lumbar. Métodos: Se realizó un estudio de casos y controles en estudiantes de una universidad privada de la ciudad de Lima. Se valoraron el dolor lumbar y la distancia entre los bordes mediales del músculo recto abdominal mediante la escala numérica de dolor, índice cintura cadera, el cuestionario nórdico y la escala de Oswestry. Se midió la distancia los bordes mediales del músculo recto abdominal con un Caliper digital. Resultados: La media y desviación estándar de la distancia de los bordes mediales del músculo recto abdominal fue 21,9 ± 3,5. Esta y la diástasis abdominal se asociaron con el dolor lumbar. Conclusiones: Se demostró que la distancia de los rectos abdominales y el dolor lumbar en los estudiantes universitarios guardan relación.
Introduction: Chronic low back pain in university students ranges between 12.4 and 75 %. It was initially evidenced that the alteration of the musculature of the rectus abdominis may be associated with low back pain. Objective: To evaluate the association between the distance from the medial edges of the rectus abdominis muscle and the presence of low back pain. Methods: A case-control study was conducted in students of a private university in the city of Lima. Low back pain and the distance between the medial edges of the rectus abdominis muscle were assessed using the numerical pain scale, the waist-hip index, the Nordic questionnaire and the Oswestry scale. The distance between the medial edges of the rectus abdominis muscle was measured with a digital Caliper. Results: The mean and standard deviation of the distance from the rectus abdominis was 21.9 ± 3.5. This and abdominal diastasis were associated with low back pain. Conclusions: The distance between the medial edges of the rectus abdominis muscle and low back pain in university students was shown to be related.
ABSTRACT
I. Objective: to highlight the clinico-MRI pro?le of lumbar disc herniation on sciatic lumboradiculgia in bi- river hospital settings (cases of Kinshasa and Brazzaville). This was a II. Materials and methods: retrospective, documentary and multicenter study of 302 patients who performed lumbar MRI examinations in 18 months in hospitals in Kinshasa and Brazzaville. The mean age of patients was 53.4 years. The most represented age group III. Results: was 50 to 59 years old. The female sex was predominant (55.4%) with a ratio of 0.79. The majority of patients (68.2%) came from Kinshasa. Lumboradiculalgia was the most predominant indication with (49.3%), followed by low back pain (48%). The majorityof MRI examinations (91.4%) were performed without injection of contrast product. T1 and T2 weightings were performed in 100% of patients. Diseased disc degeneration was found at (41.7%) and lumbar disc herniation at (27.2%). The MRI examination was normal in (47%) of the patients. Based on potentially clinically positive relevance, only 48.7% of our MRI diagnoses were clinically positive. Age (p=0.000), lumboradiculalgia (p=0.000) and specialist physician prescription (0.039) had a statistically signi?cant relationship with clinically positive diagnosis. HDL is a pathological reality in the hospitals of IV. Conclusion: Kinshasa and Brazzaville. The MRI pro?le found mainly corroborates the observations of the literature. Lumbar disc herniation and degenerative disc disease remain the most frequently encountered pathologies on magnetic resonance imaging in hospitals in Kinshasa and Brazzaville. They are at the origin of the lumbar spinal syndrome and affect the young population. The posterolateral disc herniation remains the most frequently encountered subtype with predominance of damage to the ?oors: L4-L5 and L5-S1

ABSTRACT
Abstract Objective To evaluate the impact of the severity of lumbar degenerative disease (LDD) on sagittal spinopelvic alignment. Methods In total, 130 patients (mean age: 57 years; 75% female) with LDD-associated low-back pain were prospectively included. The severity of the LDD was defined by the following findings on anteroposterior and lateral lumbar spine radiographs: osteophytosis; loss of of height of the intervertebral disc; terminal vertebral plate sclerosis; number of affected segments; deformities; and objective instability. The disease was classified as follows: grade 0-absence of signs of LDD in the lumbar spine; grade I - signs of LDD in up to two segments; grade II - three or more segments involved; grade III - association with scoliosis, spondylolisthesis, or laterolisthesis. Spinopelvic radiographic parameters, including pelvic incidence (PI), lumbar lordosis (LL), discrepancy between the PI and LL (PI-LL), pelvic tilt (PT), and sagittal vertical axis (SVA), were analyzed according to the LDD grades. Results The radiographic parameters differed according to the LDD grades; grade-III patients presented higher SVA (p= 0.001) and PT (p= 0.0005) values, denoting greater anterior inclination of the trunk and pelvic retroversion when compared to grade-0 andgrade-I subjects. In addition, grade-III patients had higher PI-LL values, which indicates loss of PI-related lordosis, than grade-I subjects (p= 0.04). Conclusion Patients with more severe LDD tend to present greater spinopelvic sagittal misalignment compared to patients with a milder disease.
Resumo Objetivo Avaliar o impacto da graduação da doença degenerativa lombar (DDL) sobre o alinhamento sagital espinopélvico. Métodos Ao todo, 130 pacientes (dade média: 57 anos; 75% do sexo feminino) com dor lombar associada a DDL foram prospectivamente incluídos. A gravidade da DDL foi definida pelos seguintes achados nas radiografias anteroposterior e de perfil da coluna lombar: osteofitose; perda de altura do disco intervertebral; esclerose na placa vertebral terminal; número de segmentos afetados; deformidades; e instabilidade objetiva. Os pacientes foram graduados segundo a DDL da seguinte maneira: grau 0-ausência de sinais de DDL na coluna lombar; grau I - sinais de DDL em até dois segmentos; grau II - envolvimento em três ou mais segmentos; grau III - quando associada a escoliose, espondilolistese ou laterolistese. Parâmetros radiográficos espinopélvicos, como incidência pélvica (IP), lordose lombar (LL), discrepância entre a IP e a LL (IP-LL), versão pélvica (VP), e eixo vertical sagital (EVS) foram analisados de acordo com os graus de DDL. Resultados Houve diferença nos parâmetros radiográficos comparando-se os graus de DDL, com os pacientes de grau III apresentando maiores valores de EVS (p= 0,001) e VP (p= 0,0005), o que denota maior inclinação anterior do tronco e maior retroversão pélvica do que os pacientes de graus 0 e I. Pacientes de grau III também apresentaram maiores valores de IP-LL, o que denota perda da lordose relativa ao valor da IP, do que pacientes grau I (p= 0,04). Conclusão Pacientes com DDL mais grave demonstraram uma tendência a maior desalinhamento sagital espinopélvico comparados com pacientes com graus mais leves.

Conclusiones: De acuerdo con lo publicado por los autores, el plasma rico en plaquetas es una alternativa efectiva en el tratamiento de la enfermedad degenerativa discal por la producción de factores derivados de las plaquetas, que intervienen en la degeneración del disco intervertebral, siendo la vía intradiscal la que más se emplea(AU)
Introduction: Degenerative disc disease is a frequent condition and one of the main reasons to attend the consultation. It generates high rates of disability, useful years lost, as well as high economic costs for medical assistance and large monetary losses. Its treatment is generally conservative, although novel biological therapies are currently included. Objective: To describe the main biological properties that make platelet-rich plasma an effective therapy against degenerative disc disease. Methods: A nonsystematic review of the bibliography was carried out based on articles published, during the last ten years, in databases indexed in Infomed, such as Hinari, Ebsco, Scielo, Pubmed, Cubmed, Cocrhane, Scopus, and LILACS, in Spanish, English and Portuguese. Development: Clinical-epidemiological characteristics of degenerative disc disease were presented, as well as the biological properties that allow platelet-rich plasma to have an active function in the regeneration of the intervertebral disc or the delay of its degradation cascade. The main studies are highlighted, according to the route of administration of platelet-rich plasma and their results. Conclusions: According to what has been published by authors, platelet-rich plasma is an effective alternative in the treatment of degenerative disc disease, due to the production of factors derived from platelets, which intervene in the degeneration of the intervertebral disc, being the intradiscal pathway the most used(AU)

El dolor facetario lumbar es una de las principales causas de dolor lumbar; representa alrededor del 15-56%. La articulación facetaria estabiliza la columna vertebral, tiene un rol fundamental en el soporte, distribución del peso y regulación de los movimientos rotacionales de la columna. Por ello, el conocimiento de la anatomía y de la biomecánica de esta articulación ayuda a tener una mejor comprensión de su participación en la fisiopatología del dolor lumbar y, por ende, mejora su abordaje diagnóstico y terapéutico. Nosotros revisamos aquí los conceptos actuales de embriología, anatomía, biomecánica y la correlación clínica/imagenológica de los cambios asociados a la enfermedad degenerativa facetaria de la columna lumbar.
Low back pain is a very common reason for emergency room consultation, it is found in approximately 60% of adults, and, within it, facet lumbar pain is one of the main causes, accounting for about 15-56% of low back pain cases. The facet joint stabilizes the spine, helps to distribute loads and has a fundamental role in support, weight distribution, and rotational movements regulation of the spine. Consequently, knowledge of the anatomy and biomechanics of this joint is helpful to have a better understanding of their contribution to the low back pain pathophysiology and, therefore, improving diagnostic and therapeutic approaches. This paper aims to review the current concepts of embryology, anatomy, biomechanics, and clinical/imaging correlation of the changes associated with lumbar degenerative facet disease

ABSTRACT
Abstract Introduction: The lumbar pain is the main musculoskeletal complaint reported by the active population, and it prevents daily activities such as walking. Objective: To assess muscle recruitment and the co-contraction of the trunk muscles during different walking speed in individuals with and without chronic lumbar pain. Method: Thirty-four sedentary young women attended the study, in which 18 belonged to the lumbar pain team (LPT) and 16 to the team without lumbar pain (WLP). We assessed the electromyography activity of the internal oblique (IO) local muscle and lumbar multifidus (MUL), and global external oblique (EO), abdominal rectus (AR) and lumbar iliocostalis (LIC), during walking. The electromyography analysis was performed from the average of the linear envelope value, normalized by the peak of muscle activation. The muscle co-contraction (IO/MUL, EO/LIC, AR/LIC, IO/EO, and the abdominal/paravertebral muscle groups) was calculated with the Falconer and Winter formula. The Shapiro-Wilk test, Multivariate Analysis, mixed Variance Analyses with Bonferroni post-hoc, and Pearson (p < 0.05) correlation coefficient were made by the statistical analysis. Results: In the WLP we could notice that the higher the speed, the higher the MUL activation. The co-contraction data demonstrated that IO/MUL muscles activate 20% more in the LPT, during the preferred speed; however, in the WLP, the results showed that the higher the walking speed, the higher the EO/LIC (21.8%) and IO/MUL (17.8%) muscles activation. Conclusion: The recruitment of local muscles doesn't differ among the evaluated groups and conditions; however, in WLP, the higher the MUL muscle action, the higher the walking speed.
Resumo Introdução: A dor lombar (DL) é a principal queixa musculoesquelética relatada na população ativa e incapacita atividades do cotidiano, como a marcha. Objetivo: Avaliar o recrutamento e co-contração dos músculos do tronco durante diferentes velocidades de marcha em indivíduos com e sem DL crônica. Método: Participaram 34 mulheres jovens, sedentárias, 18 compuseram o grupo DL (GDL) e 16 o grupo sem DL (GC). Foi avaliada a atividade eletromiográfica dos músculos locais oblíquo interno (OI) e multífido lombar (MUL), e globais oblíquo externo (OE), reto abdominal (RA) e iliocostal lombar (ICL), durante a marcha. A análise eletromiográfica foi realizada a partir da média do valor de envelope linear, normalizada pelo pico de ativação muscular. A co-contração muscular (OI/MUL, OE/ICL, RA/ICL, OI/OE e os grupos musculares abdominais/ paravertebrais) foi calculada com a fórmula de Falconer e Winter. A análise estatística foi feita por meio do teste Shapiro-Wilk, Análise Multivariada, Análise de Variância mista com pos-hoc bonferroni e coeficiente de correlação de Pearson (p < 0,05). Resultados: No GC podemos perceber que, quanto maior a velocidade, maior a ativação do MUL. Os dados de co-contração demonstraram que os músculos OI/MUL ativam 20% a mais no GDL, durante a velocidade de preferência, no GC, os resultados mostram que quanto maior a velocidade de marcha, maior a ativação dos músculos OE/ICL (21,8%) e OI/MUL (17,8%). Conclusão: O recrutamento dos músculos não difere entre os grupos e condições, contudo foi observado no GC que quanto maior a ação do músculo MUL maior é a velocidade de marcha.

Introducción La cirugía endoscópica de columna ha demostrado ser una opción en el tratamiento de hernias discal y estenosis foraminal. El abordaje más empleado es la vía transforaminal, sin embargo, este abordaje es limitado en casos de hernias discales centrales extruidas y migradas. El abordaje interlaminar completamente endoscópico ha permitido el tratamiento sintomático de hernias discales centrales extruidas y migradas en el nivel L5 S1, además es una novedosa alternativa para la resolución de las dificultades técnicas relacionadas con el abordaje posterolateral en éste nivel. El propósito del estudio es reportar los resultados obtenidos con el abordaje endoscópica interlaminar en el tratamiento de hernias discales centrales extruidas y migradas en dos años de seguimiento. Materiales y métodos Se realizó un estudio retrospectivo observacional descriptivo con las historias de pacientes que presentaron sintomatología radicular secundaria a hernia discal central en el nivel L5 S1 y que fueron tratados con cirugía por abordaje interlaminar completamente endoscópico. Se evaluaron los índices de escala visual análoga (EVA) pre y posoperatorio, el criterio Oswestry ODI y el criterio MacNab. Resultados Entre los años 2008 y 2015 se realizaron un total de 99 procedimientos en el mismo número de pacientes. Todos fueron sometidos a una técnica quirúrgica estándar bajo anestesia local y sedación. La EVA tuvo una reducción de 5,81 puntos. El ODI bajó 45,63%. Y el 88% de los pacientes tuvo una completa satisfacción frente al tratamiento. Discusión Los resultados obtenidos en esta muestra permiten considerar la fragmentectomía interlaminar endoscópica bajo anestesia local y sedación como un procedimiento seguro, preciso y efectivo en la resolución del dolor secundario a hernias discales centrales extruidas y migradas en el nivel L5 S1 que cursan con radiculopatía. El uso de anestesia local y sedación como única alternativa analgésica puede no ser la mejor opción en este tipo de técnicas Nivel de evidencia IV
Background Endoscopic spine surgery has shown to be an option for disc hernias and foraminal stenosis. Although the most used approach is transforaminal, this approach is limited in cases of extruded and migrated central hernias. The full-endoscopic interlaminar approach has led to the treatment of the lumbar pain secondary to extruded and migrated central herniated discs at L5 - S1, and is an alternative for resolving technical difficulties related to the transforaminal approach at this level. The aim of this article is to report the results obtained with a full-endoscopic interlaminar approach for the treatment of central extruded and migrated herniated discs, with a two-year follow-up. Methods A descriptive observational retrospective study was conducted using the records of patients who had a radiculopathy secondary to a central herniated disc at level L5 - S1, and who were treated with a full-endoscopic interlaminar approach. An evaluation was made of the pre-operative and post-operative visual analogue scale (VAS) scores, Oswestry ODI criteria, and MacNab criteria. Results A total of 99 procedures were performed in the same number of patients between 2008 and 2015. All were treated with a standard surgical technique and under local anaesthesia and sedation. The visual analogue score showed a reduction of 5.81 points. The ODI was down 45.63%, and 88% of the patients were completely satisfied with the treatment. Discussion The results lead us to consider that full-endoscopic interlaminar fragmentectomy under local anaesthesia and sedation is a safe, accurate, and effective procedure for the treatment of radiculopathy related to L5 - S1 extruded and migrated central hernia. Use of local anaesthesia and sedation as the only analgesic alternative may not be the best option in this type of technique. Evidence Level IV

Objective To study the clinical effect of Yaotongning capsule combined with etoricoxib for the pain and inflammation of lumbar vertebrae in elderly patients with lumbar osteoarthritis. Methods 120 elderly patients with lumbar osteoarthritis admitted to our hospital from January 2016 to June 2018 were randomly divided into the control group and the observation group, with 60 patients in each group. Patients in the control group were treated with etoricoxib, while patients in the observation group were treated with etoricoxib plus Yaotongning capsule orally. Both groups received medications for 2 weeks. Spinal pain and quality of life score changes were recorded. The inflammatory cytokines in serum TNF-α, GM-CSF, COX-2 and BMP-2 levels were monitored. The clinical efficacy was compared and drug safety profile was evaluated for two groups. Results The effective rates of the control group and the observation group were 78.33% and 91.67% respectively. The effective rate in the observation group weas significantly higher (P<0.05). After treatment, the VAS score for the patients in the observation group was significantly lower than that in the control group (P<0.05). The SF-36 score in the observation group was significantly increased (P<0.05), and the levels of TNF-α,GM-CSF and COX-2 in the serum were significantly lower than those in the control group (P<0.05), and the levels of BMP-2 were significantly increased (P<0.05). Conclusion Yaotongning capsule combined with etoricoxib in the treatment of senile lumbar osteoarthritis has definite curative effect. It significantly reduced lumbar pain, improved quality of life, inhibited inflammatory reaction, and had a better drug safety profile. The further clinical investigation for the combination therapy is warranted.
ABSTRACT
Introducción: el dolor es una experiencia multidimensional que considera los tres ejes de la salud: el biológico, el psicológico y el social. Cuando el daño estructural no es la causa esencial del dolor experimentado, tal como sucede en la lumbalgia crónica inespecífica (LCI), se hace necesario considerar los ejes no biológicos para un abordaje integral. Por lo tanto, el objetivo de este estudio es analizar la relación entre los factores psicoemocionales con la intensidad del dolor y la funcionalidad de las personas con LCI. Materiales y métodos: el tipo de estudio es no-experimental, cuantitativo y correlacional. La muestra corresponde a un n=55 usuarios de los CESFAM Sergio Aguilar, de la comuna de Coquimbo y Juan Pablo II, de la comuna de La Serena. Se aplicaron cuestionarios sobre los factores psicoemocionales: kinesofobia, catastrofismo y autoeficacia, y las variables de limitación de la funcionalidad e intensidad del dolor. Los instrumentos utilizados fueron: escala de tampa para kinesofobia (TSK 11), escala de catastrofismo del dolor (PCS), cuestionario sobre la percepción de autoeficacia, escala de funcionalidad o incapacidad por dolor lumbar Oswestry y escala visual análoga (EVA), respectivamente. Resultados: hubo una relación entre las variables catastrofismo-limitación de la funcionalidad (rho=0,537, p<0,005), catastrofismo-intensidad del dolor (rho=0,437, p=0,001), kinesofobia-limitación de la funcionalidad (rho=0,418, p=0,002) y autoeficacia-limitación de la funcionalidad (rho=-0,518, p<0,005), siendo estas correlaciones significativas estadísticamente. Discusión: los tres factores psicoemocionales se relacionan con la funcionalidad. No obstante, solo el catastrofismo se relaciona con la intensidad del dolor. Por ende, es relevante que el kinesiólogo considere en su intervención terapéutica estos factores para enfocar el posterior abordaje kinésico con una visión e interacción multidisciplinar.
Introduction: pain is a multidimensional experience that considers the three axes of health: biological, psychological and social. When structural damage is not the essential cause of the pain experienced, as it happens in non-specific chronic low back pain (NSCL), it is necessary to consider the non-biological axes for an integral approach. Therefore, the objective of this study is to analyze the relationship between psychoemotional factors with pain intensity and functionality of persons with NSCL pain. Materials and Methods: the type of study is non-experimental, quantitative and correlational. The sample corresponds to n=55 users of the CESFAM Sergio Aguilar, of the commune of Coquimbo and Juan Pablo II, of the commune La Serena. Questionnaires were applied on psychoemotional factors: kinesophobia, catastrophism and self-efficacy, and the variables of limitation of the functionality and intensity of pain. With the instruments: Tampa scale for kinesophobia (TSK 11), pain catastrophism scale (PCS), self-efficacy perception questionnaire, Oswestry functionality scale and analogous visual scale (EVA) respectively. Results: there was a relationship between the variables catastrophism - limitation of the functionality (rho=0,537, p<0,005), catastrophism - intensity of pain (rho=0,437, p=0,001), kinesophobia - limitation of the functionality (rho=0,418, p=0,002) and self-efficacy-limitation of the functionality (rho = - 0,518, p<0,005), these correlations being statistically significant (p<0,005). Discussion:tThe three psychoemotional factors are related to functionality. However, only catastrophism is related to pain intensity. Therefore, it is relevant that the physical therapist considers these factors in his therapeutic intervention, in order to focus the subsequent kinesthetic approach with a multidisciplinary vision and interaction.

ABSTRACT BACKGROUND AND OBJECTIVES: Changes in motor control may contribute to muscle recruitment deficits. The objective of this study was to evaluate strength, endurance, and recruitment of the torso muscles. METHODS: We evaluated 35 women, divided into two groups: chronic low back pain (LBPG, n=20) and control (CG, n=15). The clinical conditions, incapacity, level of pain, strength, endurance and the muscles recruitment: internal oblique (IO) and external oblique (EO), rectus abdominis (RA), lumbar iliocostal (LI) and lumbar multifidus (LM) were evaluated. MANOVA, MANCOVA and Kruskal-Wallis were used. RESULTS: There was no significant difference between groups in the muscle strength test (p<0.172). The control group showed the greater capacity for muscle endurance in the muscle endurance test (p<0.001). In muscle recruitment, the chronic low back pain group presented greater muscle activation, which was evident in the global stabilizing muscles EO and RA (p<0.05). CONCLUSION: Women with back pain had reduced muscular endurance and greater recruitment of the global muscles when compared to women with no back pain.
RESUMO JUSTIFICATIVA E OBJETIVOS: Alterações no controle motor podem contribuir para déficits no recrutamento muscular. Sendo assim o objetivo deste estudo foi avaliar a força, resistência e o recrutamento dos músculos do tronco. MÉTODOS: Foram avaliadas 35 mulheres, divididas em dois grupos: dor lombar crônica (GDL, n=20) e controle (GC, n=15). Avaliou-se as condições clínicas, incapacidade, nível da dor, força, resistência e recrutamento dos músculos: oblíquo externo (OE) e interno (OI), reto abdominal (RA), iliocostal lombar (ICL) e multífido lombar (MUL). Utilizou-se MANOVA, MANCOVA e Kruskal-Wallis. RESULTADOS: No teste de força muscular não houve diferença significativa entre os grupos (p=0,172). O grupo controle demonstrou maior capacidade de resistência no teste de resistência muscular (p<0,001). No recrutamento muscular, o grupo dor lombar crônica apresentou ativação muscular maior, que ficou evidente nos músculos estabilizadores globais, OE e RA (p<0,05). CONCLUSÃO: Mulheres com dor lombar apresentaram resistência muscular diminuída e maior recrutamento nos músculos globais, quando comparadas às mulheres sem dor lombar.

Objective To observe the clinical efficacy of radiofrequency ablation for treatment of discogenic lumbar spinal nerve posterior branch neuralgia after vertebral column endoscope operation. Methods Thirty-six patients with discogenic lumbar spinal nerve posterior branch neuralgia after vertebral column endoscope surgery admitted to the Affiliated Hospital of Logistics University of People's Armed Police from December 2011 to December 2017 were enrolled. According to difference in therapeutic methods, they were randomly divided into two groups, 18 cases in each group. The radiofrequency ablation group was treated with X-ray imaging guided lumbar spinal nerve posterior branch radiofrequency thermo-coagulation; the drug group received oral diclofenac sodium conservative treatment, 75 mg twice daily for 3 weeks. Both groups were followed up for 6 months, visual analogue scores (VAS) were used to evaluate the pain before and after treatment, the Oswestry dysfunction index was used to assess the degree of lumbar function recovery, and the surgical complications and adverse drug reactions were observed. Results The VAS scores in the two groups were similar before treatment; after treatment for 1 month, the VAS scores in both groups were significantly lower than those before treatment (radiofrequency ablation group: 1.83±0.71 vs. 5.67±0.77; drug group: 2.22±0.43 vs. 5.28±0.67, both P < 0.05); after treatment for 3 months and 6 months, the VAS scores were increased gradually, however, the scores of radiofrequency ablation group were significantly lower than those in the drug group (3 months was 2.00±0.59 vs. 3.39±0.70, 6 months was 2.17±0.51 vs. 3.61±0.50, both P < 0.05), moreover, the excellent and good rates of postoperative pain efficacy and of Oswestry dysfunction index improvement in the radiofrequency ablation group were significantly higher than those in the drug group [excellent and good rates of postoperative pain efficacy: 94.44% (17/18) vs. 22.22% (4/18), excellent and good rates of Oswestry dysfunction index improvement: 77.78% (14/18) vs. 44.44% (8/18), both P < 0.05]. There were no complications of infection and spinal nerve anterior branch injury in the radiofrequency ablation group, and 6 patients in the drug group presented mild gastric discomfort, which was relieved after symptomatic treatment. Conclusion The radiofrequency ablation is an effective method for treatment of discogenic lumbar neuralgia after vertebral column operation, compared with the conservative therapy, the ablation is more effective to relieve pain for a long time, promote the recovery of neural function, and the operation is safe with very few adverse reactions.
ABSTRACT
Introducción: La granulomatosis de Wegener (GW) es una enfermedad autoinmune sistémica caracterizada por vasculitis granulomatosa necrotizante que afecta principalmente a las vías respiratorias superiores, pulmones y riñones. Sin embargo, con menos frecuencia puede afectar a los músculos, las articulaciones, la piel, los ojos, el sistema cardiovascular y el sistema nervioso. La presencia de dolor lumbar consiste en una manifestación clínica inusual debido a la afectación del sistema nervioso. Objetivo: El objetivo de este estudio es alertar a los profesionales de la salud acerca de la posibilidad de cortar el dolor lumbar estar relacionado con la granulomatosis de Wegener, su impacto en la vida diaria del paciente, así como los signos clínicos y las formas de diagnóstico. Materiales y Métodos: Revisión de la literatura utilizando PubMed, MEDLINE, Google Scholar, SciELO, EBSCO. Los trabajos seleccionados entre 1995 y 2013 por un total de 48 obras de las cuales se seleccionaron 21 de acuerdo con sus informes de afectación neurológica, diagnóstico y tratamiento. Discusión: Los síntomas neurológicos pueden ocurrir en 22-50 por ciento de los pacientes durante el curso de la GW. sistema nervioso (SNC) central es poco frecuente (sólo 2-8 por ciento de los pacientes) dolor lumbar .Severe es una manifestación clínica poco frecuente y puede estar asociada con la participación de sistema nervioso central y periférico. CNS debido a la compresión de la médula espinal a nivel lumbar. sistema nervioso periférico debido a la compresión de las raíces nerviosas. Conclusión: La granulomatosis de Wegener es ser una enfermedad sistémica puede presentar diferentes manifestaciones clínicas De acuerdo con el sitio involucrado. Es asociaciones con el dolor lumbar es rara y la refleja la afectación neurológica. Por lo tanto, en pacientes con dolor lumbar grave sin diagnóstico confirmado, granulomatosis de Wegener no debería ser considerado.
Introduction: Wegeners granulomatosis (WG) is a systemic autoimmune disease characterized by necrotizing granulomatousvasculitis which primarily affects upper respiratory tract, lungs and kidneys. However, less frequently can affect muscles,joints, skin, eyes, cardiovascular system and nervous system. The presence of lumbar pain consists in an unusual clinicalmanifestation due to the involvement of the nervous system. Objective: The objective of this study is to alert health professionalsabout the possibility that severe lumbar pain be related to Wegeners granulomatosis, its impact on the patients dailylife as well as clinical signs and diagnosis forms. Materials and Methods: Literature review using PubMed, MEDLINE, GoogleScholar, SciELO, EBSCO. Selected works from 1995 to 2013 totaling 48 works of which 21 were selected according to theirreports of neurological involvement, diagnosis and treatment. Discussion: Neurological symptoms may occur in 22-50 percent of patients during the course of WG. Central nervous system (CNS) involvement is uncommon (only 2-8 percent of patients).Severelumbar pain is a rare clinic manifestation and it can be associated with the involvement of central and peripheral nervous system.CNS due to compression of the spinal cord at the lumbar level. Peripheral nervous system due to compression of nerveroots. Conclusion: Wegeners granulomatosis for being a systemic disease can present different clinical manifestations accordingto the involved site. Its associations with lumbar pain is rare and reflects its neurological involvement. Therefore, inpatients with severe lumbar pain without confirmed diagnosis, Wegeners granulomatosis should be considered.

El dolor lumbar es, entre los de espalda, el más común. Las cifras de prevalencia en adolescentes lo convierten en un grave problema de salud pública. El objetivo de este trabajo es realizar una revisión bibliográfica del tema del dolor lumbar en la adolescencia, haciendo hincapié en las cifras de prevalencia por países, sus causas y los factores de riesgo asociados a él. Los resultados muestran que existen ciertas causas y factores de riesgo asociados al dolor lumbar en los que existe acuerdo (el sexo, la herencia genética, la inactividad física o la postura sedente y el mobiliario inadecuado) mientras que en otros, los diversos autores llegan a resultados diferentes. En conclusión, se puede afirmar que el dolor lumbar en adolescentes es una enfermedad de alta prevalencia, más frecuente en mujeres y en personas sedentarias, que predispone para sufrirlo en la edad adulta.
Low back pain is the most common among back pain. Prevalence figures in adolescents make it a serious public health problem. The objective of this study is to carry out a bibliographic review of the topic of low back pain in adolescence, with emphasis on the prevalence figures by country, their causes and the risk factors associated with it. The results show that there are causes and risk factors associated with low back pain in which there is agreement (gender, genetic inheritance, physical inactivity or sedentary posture and inappropriate furniture), while in others, the various authors reach different results. In conclusion, it can be affirmed that low back pain is a disease of high prevalence, more frequent in women and in sedentary people, predisposing to suffer it in adulthood.

Introduction: Chronic lumbar pain is one of the suffering causes worldwide, and emotions influence the individual's response to the disease. Objective: To relate the emotional states of anxiety, depression and anger in patients with chronic lumbar pain with some clinical variables (time of evolution, intensity and persistence). Methods: Observational, descriptive-correlational study at Cartagena Polyclinic between September 2012 and April 2013. Universe: 30 patients, sample: 25 patients, selected by intentional sampling. Techniques employed: structured interview, visual analogue scale, Idare, Staxi-2, Beck Inventory. Results: Male sex and engagement configuration (84 percent) appear as identification variables, occupation: workers (76 percent), age: young adults (52 percent), mean schooling (40 percent) were identified as identification. The clinical variables predominated in the evolution period from 13 to 24 months (56 percent), with mild pain intensity (48 percent) and intermittent persistence (84 percent). Emotional states showed average percentages of state anxiety (60 percent), high trait anxiety (56 percent), moderate depression (40 percent), and mild anger status, moderate as trait (48 percent), (52 percent). Conclusions: The presence of high percentages of anxious symptoms, depression and anger manifested in the sample studied was similar to that described in the literature. Anxiety and anger as a personality trait was not related to the clinical variables studied, associations were found between intensity and persistence of pain with depression and anxiety and anger as a state and between time evolution of disease and anger state(AU)

El incremento de la cantidad de trabajadores de oficina ha conllevado a un aumento del tiempo que se pasa en postura sedente de manera continua; por tal razón, esta condición de trabajo ha sido investigada con el propósito de comprender las manifestaciones de dolor o incomodidad resultantes de hacer trabajos en dicha demanda postural. Objetivo: comparar los datos basales de percepción de incomodidad debida al dolor lumbar con aquellos en función del uso prolongado de la silla, en presencia (CB) o no (SB) de variaciones en la inclinación del asiento. Materiales y métodos: se incluyeron diez trabajadores de oficina; se les asignó la silla modificada o estándar para uso continuo en la jornada laboral durante ocho meses, con seguimiento mensual mediante la medición de incomodidad con la Escala análoga visual. Los datos se analizaron de manera descriptiva y mediante métodos estadísticos, según la distribución de cada conjunto de datos. Resultados: revelan diferencias significativas y una potencial ventaja de la silla CB frente a la silla SB, de acuerdo con la comparación de medias de los reportes de incomodidad en la región lumbar (p=0,04). Además, se encontró que los trabajadores que recibieron intervención ergonómica en la oficina redujeron el aumento de incomodidad en la jornada laboral y el período de seguimiento, comparado con el grupo control. Conclusiones: las variaciones en la inclinación del asiento realizadas en forma dinámica y continua durante lapsos largos (silla dinámica CB) influyen de manera positiva en la disminución de la percepción de incomodidad en trabajadores de oficina.
The increase in the amount of office workers, has led to an increase on the continuous time they expend in a sitting posture. Hence, this working situation has been investigated to understand pain or discomfort manifestations under this postural demand. Objective: to compare the basal data of discomfort perception due to back pain with those related to the extended use of chairs, when there is presence (or absence) of seat tilt variations. Materials and methods: the study involved a group of ten office workers. This subjects used a typical office chair (SB chair) or a modified one (CB chair) when they were at work. Then, there was a monthly evaluation of the discomfort using a Visual Analog Scale, during an eight months survey time. Data was descriptively analyzed using statistical methods, depending on the distribution of each data set. Results: revealed potential advantage of CB chair over the SB chair, considering the average comparison of discomfort in the lumbar region (p=0,04). In addition, workers receiving office ergonomic intervention reduced their daily discomfort during the monitored period, compared with the control group. Conclusion: dynamic and continuous variations of seat tilt during long periods of time have a positive influence in reducing the perception of discomfort in office workers.
O incremento da quantidade de trabalhadores de escritório, tem levado a um aumento do tempo que se passa em postura sedentária de maneira contínua, por este motivo, esta condição de trabalho tem sido investigada com o propósito de compreender as manifestações de dor ou incomodidade; resultado de realizar trabalhos em dita demanda postural. O objetivo do estudo foi comparar os dados basais de percepção de incomodidade devida à dor lombar com aquelas em função do uso prolongado da cadeira, em presença (CB) ou não (SB) de variações na inclinação da cadeira. Para isto, incluíram-se 10 trabalhadores de escritório, atribuindo-lhes uma cadeira modificada ou standard mensal mediante a medição de incomodidade com a Escala Análoga Visual. Os dados analisaram-se de maneira descritiva e mediante métodos estatísticos, segundo a distribuição de cada conjunto de dados. Os resultados revelaram diferenças significativas e uma potencial vantagem da cadeira CB gente à cadeira SB, tendo em conta a comparação de medias dos reportes de incomodidade na região lombar (p=0,04).
