| To investigate the effect of silver needle heat conduction combined with needle-knife on chronic lower back pain （LBP） and its effect on lumbar function, lumbar flexion range and quality of life. Methods: In total of 76 patients with LBP who came to the hospital from June 2014 to October 2016 were randomly divided into a control group （n=38） and an observation group （n=38） according to the random number table generated by computer. The control group was treated with silver needle heat conduction therapy, and the observation group was treated with silver needle heat conduction combined with needle-knife. Clinical efficacy, pain, lumbar function, lumbar flexion range and quality of life in 2 groups were compared. Results: The total effective rate of the observation group was 94.74%, which was significantly higher than that of the control group （78.95%）, and the difference was statistically significant （P<0.05）. After treatment and 6 months after treatment, VAS score and ODI index of 2 groups gradually decreased and were significantly lower than those before treatment （P<0.05 or P<0.01）, and the observation group was significantly lower than the control group （P<0.05 or P<0.01）. The lumbar flexion range of 2 groups increased gradually and was significantly higher than that before treatment （P<0.01）, and the observation group was significantly higher than the control group （P<0.01）; after treatment, the level of pain, elevation, sitting, walking, standing, self-care, social life, sleep, pain changes and travel scores of 2 groups were significantly lower （P<0.05 or P<0.01）, and the observation group was significantly lower than the control group （P<0.05 or P<0.01）. Conclusion: Silver needle heat conduction combined with needle-knife on chronic LBP can significantly reduce the pain response, increase the lumbar flexion range, improve the lumbar function and the quality of life of patients, and is worthy of clinical use. |
