Objectives : To evaluate the effectiveness of direct moxibustion in patients with failed back surgery syndrome (FBSS). Methods : 5 patients (3 females and 2 males) with FBSS underwent direct moxibustion on ouch points (阿是穴) for 10 to 15 weeks (once a week). The effectiveness of the treatment was evaluated with NRS (numerical rating scale), ODI (Oswestry disability index), BDI (Beck depression inventory) score, SF-36 (short form 36 health survey) score and PSQI (Pittsburgh sleep quality index) before and after the treatment. Results : Within observation period, average value changed from 10.0 to 4.2 in NRS of pain, from 37.0 to 20.6 in ODI, from 20.6 to 12.0 in BDI score, 42.2 to 62.6 in SF-36 score, and from 8.6 to 5.2 in PSQI. Conclusions : Direct moxibustion on FBSS patients showed more or equivalent effectiveness when compared to conventional FBSS treatment modalities.
