Eficácia da ventosaterapia para tratamento da dor lombar inespecífica: um ensaio clínico aleatório controlado por placebo

Abstract

Introduction: Non-specific low back pain is a public health problem, in which changes in the lifestyle of the population and overload in the lower back predispose the individual to the onset of this clinical condition. Objectives: To analyze the effects of wind therapy in the treatment of nonspecific low back pain; to evaluate the effects of the technique on flexibility, skin and deep sensitivity and on fear and refusal. Methods: Participants were randomized in the acupuncture placebo and wind therapy groups, and individuals between 18 and 60 years old with non-specific low back pain were recruited. The evaluation consisted of the 11-point numerical scale (NRS), FABQ, algometer, esthesiometry, Wells Bank and Skin Extension Test. Results: The sample consisted of 19 participants, where it was observed that for skin sensitivity, pressure pain threshold, fear and refusal, and flexibility with the skin extension test, the acupuncture placebo and wind therapy groups did not present significant changes. whereas for flexibility with the Wells Bank, it showed significant improvements (p <0.05) for the wind therapy group, and for NRS after the intervention, there was a reduction in pain intensity for both groups (p <0.05). . Conclusion: Wind therapy was effective in reducing nonspecific low back pain and improving flexibility through the Wells Bank. In the variables pain threshold by mechanical stimulation, skin sensitivity, flexibility with the skin extension test and fear and refusal both treatments presented similar values.
