Low back pain (LBP) is very common, widespread, and represents a multidimensional syndrome. It affects physical activity and function, health-related quality of life, and employment status. The lifetime prevalence of acute low back pain is approximately 80%. The prevalence of chronic low back pain (CLBP) in the general population is reported to be 8% to 21%. Several clinical trials have provided evidence to support the efficacy of acupuncture in the treatment of LBP, however, the optimal acupuncture treatment for CLBP has not been extensively studied.

Low back pain (LBP) is a common, widespread and multifaceted syndrome and represents one of the leading sources of years lived with disability. In Switzerland, patients with LBP generated mean annual costs of 467 million Euro in 2016 and 2017, respectively. Moreover, quantity of prescriptions per patient was reported to be 5 - 6 per year, causing pain medication costs of 4.7 million Euro. It is estimated that 20% of acute LBP can manifest as chronic LBP (CLBP), defined as pain lasting longer than three months. CLBP does not only negatively impact the quality of life, functional status, and working capability of those suffering, but also plays a pivotal role of the large annual health care costs for LBP in Switzerland and worldwide. Pharmacological therapies with at least a small magnitude of effect for pain relief in CLBP include non-steroidal anti-inflammatory drugs, opioids, Tramadol and antidepressants. Additionally, non-pharmacological therapies with at least a small magnitude of effect for pain relief in CLBP include exercise, motor control exercise, Yoga, mindfulness-based stress reduction, electromyography biofeedback, cognitive-behavioral therapy, multidisciplinary rehabilitation and acupuncture. In this context and during the last decades and centuries, different acupuncture methods evolved, among others, the acupuncture method newly termed Swiss low back acupuncture (SLBA). The SLBA originates from Jiu Gong Points (九宫穴), which is the abbreviation for Nine Spinal Points (脊椎九宫穴). The particular sites of Jiu Gong Points were evolved from the eight trigrams and nine palaces square (Ba Gua Jiu Gong fang 八卦九宫方). The eight trigrams (Ba Gua 八卦) are a set of metaphysical and philosophical sigmas composed of three components of yin and yang, which are the essential concept of all-natural phenomena. Nine palaces (Jiu Gong, 九宫), an element of the eight trigrams, correspond to the nine regions in ancient China (Jiu Ye, 九野). They represent the four main (North=kidney; South=heart; East=liver; West=lung; Earth=spleen) and four secondary cardinal points and the earth as the center. In 825 patients with LBP due to lumbar herniated disc, it has been shown that hot needle acupuncture (热针) using Jiu Gong Points around the most significant lesion of the lumbar vertebrae results in good improvements of pain. The uncontrolled study reported a cure of LBP in 65.2% of cases and an improvement of clinical symptoms of 32.4%. Due to the positive report, the hot needle acupuncture using Jiu Gong Points has further evolved in Switzerland and might be a promising tool to treat CLBP, since the optimal method of acupuncture against CLBP remains to be elucidated. However, the efficacy of SLBA has never been quantitatively compared to SA and a randomized clinical trial is warranted to provide first robust evidence on its performance in CLBP. Therefore, the purpose of this study is to conduct the first randomized clinical trial comparing SLBA and SA on pain relief in patients with CLBP.
