Intervention model description: In the electroacupuncture group, electroacupuncture was applied to selected acupoints for 30 min per treatment, and the treatment was performed 3 times per week (1-2 days between each treatment), receiving a total of 12 treatments in 4 weeks. Considering the possibility of uncontrollable factors such as temporary outings and overtime work during the treatment period, we will allow subjects to miss a maximum of 3 treatments, including 2 consecutive treatments.

In the sham acupuncture group, placebo-needle treatment was performed on nonacupoints for 30 min per treatment, and the treatment was performed 3 times per week (with an interval of 1-2 days between treatments), with a total of 12 treatments received in 4 weeks. Considering the possibility of uncontrollable factors such as temporary outings, overtime work, etc. during the treatment period, we will allow subjects to miss a maximum of 3 treatments, including 2 consecutive treatments.
Primary purpose: TREATMENT

Brief summary: Low back pain (LBP) is a prevalent clinical condition characterized by pain localized between the lower edge of the 12th rib and the gluteal fold.The incidence of LBP has been escalating annually.An epidemiological survey encompassing 204 countries and territories globally projects a stark increase in the affected population, from an estimated 619 million in 2020 to a projected 843 million by 2050.LBP can affect individuals across all age groups, with a lifetime prevalence ranging from 60% to 80%, significantly impairing quality of life. Discogenic low back pain (DLBP), attributed to degenerative changes in the intervertebral discs, is the predominant subtype of LBP, comprising approximately 39% of all LBP cases. Disc degeneration typically initiates in early adulthood and progresses with age, potentially leading to DLBP.As the population ages, DLBP has emerged as a major contributor to disability worldwide, imposing a substantial burden on both individuals and society. Current international guidelines establish the foundation for surgical and pharmacological interventions for DLBP.However, considering the adverse effects and economic implications associated with surgical and medical treatments, there is a growing inclination towards recommending non-pharmacological therapies.These include physiotherapy, self-management, and psychotherapy, with a concurrent reduction in emphasis on pharmacological and surgical options.

Acupuncture and moxibustion are integral components of traditional Chinese medicine, garnering global recognition for their role in restoring the equilibrium of yin and yang within the human body . Electroacupuncture, a modern derivation of traditional acupuncture, has been extensively applied worldwide for the management of various painful conditions, including headache, myofibromyalgia, neck pain, and cancer-related pain. Despite its broad application, a limited number of clinical efficacy and safety studies have been conducted on electroacupuncture for the treatment of discogenic low back pain (DLBP), thereby necessitating a scientific foundation for its therapeutic use .

The present study aims to investigate the clinical efficacy and safety of electroacupuncture in the treatment of DLBP using an evidence-based medical approach. By employing a multicenter, randomized, and sham-controlled study design, this investigation seeks to provide a robust evidence-based medical foundation for the use of electroacupuncture in DLBP treatment.

Participants will be randomly assigned to either the acupuncture group (experimental group) or the sham acupuncture group (control group) in a 1:1 ratio, akin to a lottery drawing. Following enrollment, participants will undergo a 4-week, 12-session intervention, followed by three follow-up visits at 4, 12, and 24 weeks post-treatment. The investigators will assess participants' low back pain, lumbar spine function, and quality of life through telephone communication or on-site questioning at these designated follow-up intervals.

Needling may result in minor bleeding, pain, or hematoma at the needle site, and rare infections or allergic reactions may occur. Adverse reactions to needling, such as dizziness or nerve damage, are exceedingly rare.

Participants in this study may confer direct medical benefits, such as remission of symptoms, or may not, with outcomes ranging from no remission to potential exacerbation of the condition . However, the knowledge gained from this study is anticipated to benefit future people with similar conditions .

In addition to this study , participations may opt for treatment with modern rehabilitation medicine modalities or medications, including shortwave therapy, intermediate frequency therapy, or oral analgesics . This study would not impose any costs beyond the participants' regular medical treatment, and the investigators will cover all study-related medical expenses (including acupuncture treatment costs, needle costs, and scale evaluation costs) . The investigators are legally committed to maintaining the confidentiality of the participants' study records.
