Objective To observe the clinical efficacy of acupuncture and medicine combined with core stability training in the treatment of patients with nonspecific low back pain.

Methods A total of 106 patients with nonspecific low back pain were selected as study subjects, and they were randomly divided into control group and observation group, with 53 cases in each group. The control group was treated with core stability training, while the observation group was given acupuncture and medicine combined with core stability training, and both groups were continuously treated for 4 weeks. Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) score and multifidus surface electromyography indicators average electromyography (AEMG), root mean square (RMS), median frequency (MF), mean power frequency (MPF) before and after treatment, assessment of lumbar muscle endurance, lumbar range of motion, clinical efficacy and adverse reactions during treatment were compared between the two groups.

Results After treatment, the scores of ODI and VAS were (22.56±2.63) and (2.29±0.28) in the observation group, which were lower than (29.11±3.14) and (2.85±0.26) in the control group(P < 0.05). The scores of ODI and VAS of two groups were lower than those before treatment(P < 0.05). AEMG and RMS in two groups were higher than those before treatment (P < 0.05). After treatment, the AEMG and RMS of multifidus were (530.87±36.81) μV and (256.27±17.16) μV in the control group, which were lower than (579.92±40.36) μV and (279.91±21.35) μV in the observation group(P < 0.05). After treatment, MF and MPF of the observation group were (184.89±12.15) Hz and (179.84±13.67) Hz, respectively, which were lower than (218.35±13.42) and (207.41±13.38) Hz in the control group, and MF and MPF of the two groups were lower than those after treatment, the static holding time and dynamic completion frequency of lumbar muscle endurance test in both groups were lengthened or increased, and were longer or higher in the observation group than those in the control group (P < 0.05). After treatment, the ranges of motions of forward flexion, rear protraction, left-right flexion and left-right rotation of lumbar in two groups were larger than before treatment, and the above ranges of motions were higher in the observation group than those in the control group (P < 0.05). After treatment, the total clinical effective rate was 88.68% in the observation group, which was higher than 71.70% in the control group (P < 0.05). No obvious adverse reactions occurred in the two groups during treatment.

Conclusion Acupuncture and medicine combined with core stability training can reduce the pain score of patients with nonspecific low back pain, improve the lumbar nerve function and muscle function, and enhance the lumbar range of motion, and has higher integral security.
