ABSTRACT
More than 60% of nursing workers have an episode of low back pain for one year, causing a negative socioeconomic impact, as this is one of the major causes of absence from work. Auriculotherapy is a low-cost, non-invasive acupuncture technique that uses the auricular pavilion as a microsystem of the human organism mapped by points that when stimulated can treat several ailments. Thus, this study aims to verify the efficacy of mustard seed (Brassica juncea) auriculotherapy in alleviating pain, improving functionality and lumbar mobility of female technical professionals and nursing assistants with chronic low back pain. A blind randomized clinical trial was conducted with two groups: one group used mustard seeds for acupressure in the ear points “Shen-Men,” “Kidney,” “Sympathetic,” and “Lumbar Spine”; the placebo group used low density polyurethane foam in place of seeds. Each group performed four auriculotherapy sessions, one per week. The groups were analyzed using infrared thermograms and pressure algometry for pain, finger-floor measurement for mobility and Roland-Morris Questionnaire for spine functionality, with a 95% confidence interval. Mustard seed auriculotherapy reduced the average temperature in the thermograms analyzed by 0.8 °C, as well as increased the pain threshold to lumbar spine pressure of the volunteers by 0.4 Kgf, which shows a significant improvement of low back pain. Therefore, mustard seed auriculotherapy was effective in alleviating low back pain.
