Aims and objectives To compare the efficacy of Chinese and French ear acupuncture in people with chronic back pain. Background Chronic back pain is a common public health problem worldwide. An intervention for this condition is ear acupuncture. Several approaches are used for ear acupuncture, particularly the Chinese and French guidelines. Methods An open, randomised and controlled clinical trial, followed the recommendations of the CONSORT Checklist. One hundred and eleven people were selected and randomised into three groups: Chinese ear acupuncture, French ear acupuncture and Control. Evaluations were performed before the first intervention session (initial), 1 week after the fifth session (final) and after a fifteen‐day follow‐up period (follow‐up), using the Brief Pain Inventory, Rolland Morris Disability Questionnaire, and a thermal imaging camera. For data analysis, the Generalized Estimating Equation Model was applied, with significance level set at 5%. Results Pain severity was significantly decreased by Chinese ear acupuncture throughout intervention period. Both types of ear acupuncture affected pain interference with daily activities. However, in the comparison between initial and final evaluations, only Chinese ear acupuncture produced statistically significant results. A reduction in physical disability was observed in both ear acupuncture‐treated groups during the intervention period and, although Chinese ear acupuncture failed to induce significant changes in tissular temperature at individual time points, a significant increase in cutaneous temperature was detected after the follow‐up period in the dorsal region of individuals treated with Chinese ear acupuncture. Importantly, at this time point, the mean difference between Chinese and French ear acupuncture revealed a more benefic effect of Chinese procedure on this parameter. Conclusions The individualised treatment based on the Chinese precepts showed, in an overall evaluation, better results for management of chronic back pain in the present study. Relevance to clinical practice Ear acupuncture can be implemented in the nurse's clinical practice to assist the treatment of people with chronic back pain.
