Objective:To observe the clinical efficacy of YANG’s pricking-cupping therapy combined with electro-acupuncture (EA) in treating degenerative lumbar spinal stenosis (DLSS) of the wind-cold obstruction type. Methods60 patients with DLSS were randomized into treatment group and control group, 30 patients in each group. Patients in the treatment group were treated with YANG’s pricking-cupping therapy combined with EA and those in the control group were given transcutaneous electrical nerve stimulation (TENS) combined with physiotherapy. 8 weeks were regarded as a course of treatment. The clinical efficacy was observed. Changes in scores of simplified Chinese versions of Swiss Spinal Stenosis (SC-SSS) Questionnaire were compared.  Results:①During the trial, there was one drop-out in the treatment group, and 59 patients completed the trial. ②The total effective rate was 89.66% and 80.00% in the treatment and control groups, respectively, with no significant difference between the two groups (P>0.05), Clinical efficacy in the treatment group was superior to that in the control group (P<0.05). ③There were statistically significant differences in severity of symptoms and physical function score between 4 and 8 weeks of treatment, with significant decrease in the treatment group compared to those in the control group (P<0.05).  Conclusion:Compared with physiotherapy alone, YANG’s pricking-cupping therapy combined with electro- acupuncture shows better efficacy in treating DLSS of the wind-cold obstruction type, significantly relieving pain of the waist and legs, improving intermittent claudication and alleviating numbness of the legs.
