Description of intervention(s) / exposure
acupuncture treatment for chronic low back pain orally baclofen administration.The enrolled subjects randomly were divided to: (1) control (C) group,(2) acupuncture treated (AC) group,(3) baclofen treated (BA) group, and(4) acupuncture plus baclofen treated (BA+AC) group. Treatment procedures for all groups were continued for 5 weeks, which is a standard frequency of treatments for chronic pain .
(2)Acupuncture (AC) group:
Acupuncture treatment followed the Standard Recommendation in Clinical Trial of Acupuncture (STRICTA) (18). Subjects in this group received acupuncture treatment 2 times a week for 5 weeks by certified acupuncturist. Acupuncture protocol followed the modern approach to acupuncture which incorporates neurohumoral theories of acupuncture treatment mechanism. Each patient, according to major acupuncture references, received needle in following selected acupoints: Shenshu (BL23), Dachangshu (BL25), Panguanshu (BL28) Ciliao (BL32), Kunlum (BL60), huantiao(GB30) and Yanglingquan (GB 34). Aseptic procedure and disposable, stainless, 30- gauge needles with electrical stimulation at 4-6 Hz with pulse duration of 0.5 ms were used (28, 29). Needles (0.2 mm × 40 mm, Seirin Co Ltd) were inserted into the acupoints till the subject felt dull pain or de qi. At each session 10-12 needles were used and needles were left in place for 20-25 minutes.

(3)Baclofen (BA) group:
The 30 mg/day orally administered dose of baclofen is recommended as effective dose in chronic LBP. It is also known that at this dose required for pain relief, no motor impairment was observed (24).

(4)Acupuncture plus baclofen treated (BA+AC) group:
These patients in A+B treated group received both baclofen (30 mg/day, orally) and, 2 times a week, 20-25 min acupuncture treatment (according to acupuncture method which mentioned above) for 5 weeks.

The enrolled subjects randomly were divided to: control (C) group, acupuncture treated (AC) group, baclofen treated (BA) group, and acupuncture plus baclofen treated (BA+AC) group. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants were randomized to one of the four groups, using a stratified blocked
randomization scheme and statistical software for random deviate generation.
