Abstract
Objective:To explore the differences in the efficacy of pulsed radio frequency with different parameters in patients with pain caused by lumbar disc herniation Methods:A total of 72 patients with pain caused by lumbar disc herniation admitted to Fuxin Central Hospital from April 2020 to April 2024 were selected as the study objects,and were divided into group A,B,and C by random number table method,with 24 cases in each group.The pulsed radio frequency parameters of group A were frequency 2 Hz,pulse width 20 ms,temperature 42℃,and treatment time 300 s;the parameters of group B were frequency 3 Hz,pulse width 30 ms,temperature 45℃,and treatment time 600 s;the parameters of group C were frequency 4 Hz,pulse width 40 ms,temperature 50℃,and treatment time 900 s.The pain level,lumbar spine function,lumbar spine mobility,inflammatory levels factors and the occurrence of adverse reactions were compared between the three groups.Results:At 1 week,1 and 3 months after treatment,the Pain Visual Analogue Scale scores of the three groups were lower than those before treatment,and the group C were lower than the groups A and B,the difference were statistically significant(P<0.05).At 1 and 3 months after treatment,the scores of Oswestry Disability Index in the three groups were lower than those before treatment,and the group C were lower than the groups A and B,the group B were lower than the Group A,the difference were statistically significant(P<0.05).Three months after treatment,the range of motion of lumbar spine forward flexion,posterior extension and lateral flexion in the three groups were increased than those before treatment,and group C were larger than the groups A and B,the group B were larger than the Group A,the difference were statistically significant(P<0.05).One week after the treatment,interleukin-6 and tumor necrosis factor-α in all three groups decreased compared with those before the treatment,the group C were lower than the groups A and B,and the group B were lower than the group A,the differences were statistically significant(P<0.05).The incidence of adverse reactions in the groups A,B and C were 12.50％,20.80％and 33.33％,respectively,but there was no significant difference between the three groups(P>0.05).Conclusion:There are significant differences in the efficacy of pulsed radiofrequency treatment for patients with pain caused by lumbar disc herniation with different parameters,high-frequency pulsed radiofrequency has better effects in pain relief,lumbar spine function recovery,and inflammation inhibition,but the incidence of adverse reactions was relatively high.关键词
