[Multiple central clinical test of electroacupuncture at Jiaji (EX-B 2) combined with laser needle-knife for treatment of lumbar disc herniation].

Objective: To observe therapeutic effect of electroacupuncture (EA) at Jiaji (EX-B 2) combined with laser needle-knife on lumbar disc herniation.

Methods: One hundred and twenty cases of lumbar disc herniation were divided into an Jiaji EA group, a laser needle-knife group and a combination group (Jiaji EA plus laser needle-knife) according to random number table. Changes of symptoms at different stages before and after treatment were investigated with SF-MPQ cumulative scores.

Results: All the 115 cases completed all of the study, SF-MPQ score in the combination group was significantly lower than those in the Jiaji EA group and the laser needle-knife group (P<0. 01, P<0.05), with a significant difference at the end of treatment of 2 weeks (P<0.01) between the laser needle-knife group and the Jiaji EA group, and with no significant difference at treatment of 1 week and 3 weeks (P>0.05). The recurrence rate at a half year later in the combination group was significantly lower than those in laser needle-knife group and the Jiaji EA group (P<0.05).

Conclusion: EA at Jiaji (EX-B 2) combined with laser needle-knife can significantly increase clinical therapeutic effect, alleviate pain of the patient and reduce recurrence.
