As one of the characteristic non-surgical treatments for lumbar disc herniation, single point electro-acupuncture therapy originated from the long-term clinical practice of old Chinese doctors. The author has also achieved satisfactory therapeutic effect after observing and studying under a teacher and applying it. This treatment has been applied in Shanghai Shuguang Hospital for 6 years, and nearly 1,000 patients have been satisfactorily recovered, with a low recurrence rate in the long-term follow-up. The research papers have been published one after another, which have aroused the interest and questions of some readers. For this reason, I would like to review some common problems of this therapy with respect to the author’s preliminary understanding and experience, with the hope that it will help to improve the consensus and better serve patients. The clinical indications for single point electro-acupuncture therapy can be initially summarized as follows: the therapy should be used within the scope of a clear diagnosis of lumbar disc herniation and indications for non-surgical treatment, so asymptomatic lumbar disc herniation and non-disc herniation primary lumbar pain must be excluded, excluding patients with cauda equina syndrome, spinal cone syndrome and progressive neurological damage. The more typical the symptoms of radicular pain in acute patients, the better the analgesic effect, and there is also an analgesic effect in some patients with a history of recurrent disc calcification. Previously, the efficacy of this treatment was mainly observed in patients with L4/L5 segmental herniation LIDH, but it is equally effective in patients with L5/S1 segmental herniation, except that the acupuncture points and acupuncture methods are slightly different. For patients with multi-segmental or central herniation, the priority of acupuncture points should be decided according to the severity of symptoms; some patients with postoperative pain recurrence are also effective, but the pathology and condition of this type of patients are complex, and there are many neurological symptoms and signs, so the efficacy varies greatly; recent or repeated epidural closure, sacral canal drip or paravertebral nerve root drip are also effective. After recent or repeated epidural closure, sacral drip or paravertebral nerve root block, the acupuncture area is easily “anesthetized”, and the feeling of acupuncture and efficacy are poor, and even pain is aggravated; it should be contraindicated or used with caution in patients with pregnancy, severe hypertension and heart disease; there are successful cases in children and adolescents, but continued observation is needed; lumbar disc herniation combined with lumbar spondylolisthesis of degree II or higher, ankylosing spondylitis, osteochondrosis, and lumbar spondylolisthesis. However, the pain factors of these patients are complex and should be considered in accordance with the urgency of the disease and the priority of the disease and the number of clips; individual differences in the efficacy of acupuncture are large, and theoretically there are people who are insensitive to acupuncture, and the effect is often manifested in the first few times, so it is not recommended to continue using conventional electro-acupuncture for 2-3 times if it is not effective. Generally speaking, there are great individual differences between patients in terms of condition, disease duration, pain level, relevant positive signs, and clinical data on which the size and type of herniated nucleus pulposus are based, especially the size and type of herniated nucleus pulposus (free nucleus pulposus, calcification) are not related to the type (low back pain or lower limb radiating pain) and degree of low back pain, or even the presence or absence of pain. It can be seen that there is a large blindness and randomness in the objective evaluation of the indications for this therapy, whether from clinical symptoms or from the results of auxiliary examinations. In conclusion, the current understanding of the indications for this therapy is relative, and the maximization of efficacy and safety guarantee are largely dependent on the clinician’s level of understanding of the characteristics of lumbar disc herniation and its pathological pattern, the skillfulness of acupuncture techniques, and the quality of accumulated practical experience. As one of the characteristic non-surgical treatments for lumbar disc herniation, single-acupoint electroacupuncture therapy has the characteristics of “few but precise” point selection and significant analgesic effect, and is suitable for most patients with lumbar disc herniation and low back pain. In conclusion, after many years of clinical practice and research, the efficacy of this therapy is certain and has been well received by the majority of treated patients, and I am confident in further in-depth research to elucidate the mechanism. It is especially worth mentioning that this method is applicable to most of the patients in the acute and chronic stage, characterized by significant analgesic effect, no side effects and good patient compliance, so I would like to introduce it to the majority of patients with back and leg pain.
