“…Although some studies have not found robust scientific evidence (ZHENG; YUAN; LIU, 2014) and still claim that acupuncture could be a placebo treatment, many authors have conducted research, including randomized controlled trials, and found improvements in patients (KUREBAYASHI et al, 2017;SMITH et al, 2007;MILLER et al, 2011;GAVRONSKY et al, 2012;KATANA et al, 2018). At the same time, literature reviews (SANTOS et al, 2021;FINKLER;MARTIM, 2019;ZHANG et al, 2013) and meta-analyses (MANHELMER et al, 2005;VICKERS et al, 2012) have been published., demonstrating the efficacy of treatments with acupuncture and auriculotherapy for pain, especially chronic pain.…”
