To observe and evaluate the therapeutic effects of lateral needling Jiaji(EX-B 2)combined with SET training on lumbar intervertebral disc herniation，and to compare it with the effects of conventional acupuncture treatment，so as to seek a characteristic Chinese medicine rehabilitation technology for lumbar intervertebral disc herniation，which combines modern rehabilitation concept technology with traditional Chinese medicine characteristic theory and technology. Methods:A total of 60 patients with lumbar intervertebral disc herniation were included from the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from May 2016 to May 2018，and randomly divided into the observation group and the control group，with 30 cases in each group. The observation group was treated once a day，6 times a week，for 2 weeks with lateral needling Jiaji(EX-B 2)combined with SET training. The control group was treated with routine acupuncture for 30 minutes，once a day，6 times a week，for 2 weeks. VAS pain score，low back pain symptom score table and surface electromyography(SEMG)were used to compare the situation before and after treatment. Results:1）The VAS score，low back pain symptom score of the 2 groups were lower than before(P<0.05，P<0.01)，and the observation group was better than that in the control group. 2）There was no statistically significant difference in RMS value of A，B，C and D electrodes in SEMG between the 2 groups before and after treatment(P>0.05). The RMS value of E and F electrodes in SEMG of the 2 groups was higher than before(P<0.01)，and the value in the observation group was better than that in the control group(P<0.01). 3）Comparison of the overall clinical efficacy：the treatment group was better than the control group(P<0.01). Conclusion:Lateral needling Jiaji(EX-B 2)combined with SET training can significantly reduce the pain and symptom scores of patients with lumbar protrusion，improve the clinical efficacy，activate and strengthen the muscle strength of the lumbar and abdominal core muscles and enhance the stability of the spine.
