BACKGROUND AND OBJECTIVES: The objective of this study was to evaluate the effect of neural mobilization technique on individuals with chronic low back pain, as well as analyze possible changes in pain, motor behavior and on cytokine quantification before and after treatment.

METHODS: Sixteen individuals with mean age of 30.45±10.32 years old were evaluated. The technique consisted of a total of 10 interventions, with a total duration of 10 minutes, divided into four series of 2 minutes each, with a 30-second interval between each series. The following outcomes were evaluated: pain intensity using the visual analog scale; mobility of the lumbar spine with the third finger to the ground test and hip goniometry; concentration of cytokines in serum with the multiplex technique; and quality of life with the Oswestry Disability Index, the Roland-Morris Disability Questionnaire and the World Health Organization Quality of Life Questionnaire-bref.

RESULTS: Results showed a reduction in pain intensity of approximately 70% between the assessments (p<0.001). Improvements in lumbar mobility of approximately 25.5% on the third finger to the ground test (p<0.04) and improvement in the hip joint angles (p<0.04) were also observed. A difference in cytokine concentrations, both pro-inflammatory (p<0.009) and anti-inflammatory (p<0.03), was also observed between the assessments.

CONCLUSION: The technique was able to reduce pain intensity and consequently increase the mobility of the volunteers. Additionally, a difference in cytokine concentration at the end of the treatment and an improvement in the individuals quality of life were observed.

JUSTIFICATIVA E OBJETIVOS: O objetivo deste estudo foi avaliar o efeito da técnica de mobilização neural em indivíduos com lombalgia crônica, assim como possíveis alterações na dor, no comportamento motor e na quantificação de citocinas antes e após o tratamento.

MÉTODOS: Foram avaliados 16 indivíduos com idade média de 30,45±10,32 anos. A técnica consistiu em um total de 10 intervenções, com duração total de 10 minutos, divididas em quatro séries de 2 minutos cada, com intervalo de 30 segundos entre cada série. Os desfechos a seguir foram avaliados: intensidade da dor utilizando a escala analógica visual; mobilidade da coluna lombar com o terceiro dedo ao solo e goniometria do quadril; concentração de citocinas no soro com a técnica multiplex; e qualidade de vida com o Oswestry Disability Index, Roland-Morris Disability Questionnaire and the World Health Organization Quality of Life Questionnaire-bref.

RESULTADOS: Os presentes resultados demonstraram uma redução na intensidade da dor de aproximadamente 70% entre as avaliações (p<0,001). Foram observadas melhoras na mobilidade lombar de aproximadamente 25,5% no teste do terceiro dedo ao solo (p<0,04) e nos ângulos da articulação do quadril (p<0,04). Também foi observada entre as avaliações diferença nas concentrações de citocinas, tanto pró-inflamatórias (p<0,009) quanto anti-inflamatórias (p<0,03).

CONCLUSÃO: A técnica foi capaz de reduzir a intensidade da dor e consequentemente aumentar a mobilidade dos voluntários. Além disso, foi observada uma diferença na concentração de citocinas no final do tratamento e uma melhoria na qualidade de vida dos indivíduos.
