Objective:To research the effect of lumbar spinal nerve block combined with ultrashort wave on the pain and biomechanics of lumbar back muscle of patients biomechanics with lumbar disc.Methods:98 patients with lumbar disc herniation in our hospital from February 2014 to August 2016,according to the lottery method divided into control group and research group.The control group was treated with Lumbar spinal nerve block.The research group was based on the control group treated with ultrashort wave,clinical curative effect,changes of the visual analogue scale (VAS),60 ° /s angular velocity,120° /s average apical power (AP),peak torque (PT),lumbar dorsiflexion / dorsal flexion (F/E),serum levels of substance P (SP),β-endorphin (β-EP),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α) before and after treatment,and adverse reactions were compared between two groups.Results:The total effective rate of research group was95.91％,which was significant higher than that of the control group,the difference was statistically significant (P＜0.05).After treatment,The VAS,F/E,serum levels of SP,IL-6 and TNF-α of two groups were significantly lower than those before treatment,the above indicators of research group were significantly lower than those of the control group.The AP,PT and serum levels of β-EP between two groups were significantly higher than those before treatment,the above indicators of research group were significantly higher than those of the control group (P＜0.05).No statistical difference was found in the incidence of adverse effects between the two groups (P＞0.05).Conclusion:Umbar spinal nerve block combined with ultrashort wave was more effective than lumbar paravertebral nerve block treatment alone in the treatment of lumbar disc herniation,it could effectively relieve the pain and improve the low back muscle biological mechanics performance and reduce the inflammatory response.
