The Study Of Instant Alleviating Pain Effects Of Box Moxibustion With Thunder-Fire Moxa Stick And Pure Moxa Stick For Strain Of Lumbar Muscles Of Cold-dampness Syndrome

Object:To compare the instant analgesic effect and safety of thunder-fire moxa stick and pure moxa stick therapies in treating lumber strain with cold-dampness syndrome, and provide a safer and more effective way for the disease.Methods:This was a randomized controlled trial, using single-blind method.60 sufferers of lumber strain with cold-dampness syndrome were randomly and evenly divided into the treatment group or the control group. The Treatment group was treated with thunder-fire moxa stick on Shenshu (BL23) and Ashi points, while the control group was treated with pure moxa therapy on the same points. Each session lasted for 30min. After one session, the instant analgesic effect was evaluated through the following indexes. The main indexes were Visul Analog Score (VAS), and its reduced score when the treatment just finished, and 0.5h,1.0h, 2.0h,4.0h after that. The secondary indexes contained degree of pain intensity,50% pain-relief time,100% pain-relief evaluation 24h after treatment, recrudescent condition and effective evaluation of box moxibustion.Results:60 patients had completed this research without any side effect. (1) The levels from baseline of both groups were similar (P>0.05). (2) After the treatment, the VAS scores of both groups all reduced, and there was significant difference compared with that before the treatment (P<0.05), but the difference between the two groups was not significant (P>0.05). (3) The difference of VAS reduced sore between the two groups was significant only at the point after the treatment (P<0.05), and it became not significant 0.5h,1.0h,2.0h,4.0h after(P >0.05). (4) The degree of pain intensity of both groups all reduced, but there was no significant(P>0.05). (5) The difference of 50%pain-relief evaluation 2h after treatment between the two groups was not significant(P>0.05). (6) The difference of 100% pain-relief evaluation 24h after treatment between the two groups was not significant(P>0.05). (7) The total effective rate of the treatment group was 93.33%, and that of the control group was 90.00%, without significant difference(P>0.05).Conclusion:Both thunder-fire moxa stick and pure moxa stick therapies can reduce VAS score and degree of pain intensity in treating lumber strain with cold-dampness syndrome. Only at the point after the treatment, there was significant statistical difference of the reduced score of VAS between the two groups. The instant analgesic effect of thunder-fire moxa stick is good punctually after the treatment. This research also confirms the safety of box moxibustion in treating lumber strain with cold-dampness syndrome.
