Grant 1999 (Continued) 6.1 6.4 Language: English Publication: full paper No additional information from authors Conclusions: “A 4-week course of either acupuncture or TENS had demonstrable benefits on subjective measures of pain (VAS and NHP score) and allowed them to reduce their consumption of analgesic tablets. The benefits of both treatments remained significant 3 months after completion, with a trend towards further improvement in the acupuncture patients.” Gunn 1980 Methods Participants Interventions Outcomes -Randomized (randomised blocks, blocks defined by age and operation status; the first subject from each block was assigned to the acupuncture treatment.) -No information about concealment of allocation -Nobody was blinded -Funding: Workers’ Compensation board of British Columbia -Setting: Pain Clinic in Richmond, British Columbia, Canada -Informed consent: Yes -Ethics approval: not reported -Follow-up: 56 (100%) at discharge, 53 (95%) at 12 weeks and 44 (78%) at time of writing. -Analysis: Analysis of covariance. No intention-to-treat. 56 males with chronic low-back pain of at least 12 weeks duration, who had 8 weeks of a standard clinic regimen Diagnoses: disc diseases, low-back strain, spondylitis, spondylolisthesis, radiculopathy, low-back contusion, pseudoarthrosis, disc protrusion, prolapsed disc, lumbar disc syndrome, post-laminectomy syndrome, neuropathy, sciatica, nerve root compression, facet sprain, musculo-ligamentous strain, compression fracture, interspinous ligament strain, Excluded: Psychosomatic backache. Females. Mean age: 40.6 years old (range 20 to 62 years) Working status: all off work.

Maximum of 15 treatments (average 8), once or twice a week. Training & experience unknown. Randomized to this group: 29 2) Standard therapy only (physiotherapy, remedial exercises, occupational therapy, industrial assessment). Randomized to this group: 27 1) Global improvement: 0: no improvement. Still disabled. Unable to return to any form of employment +: Some improvement. Some subjective discomfort. Able to return to lighter employment. ++: Good improvement. Slight subjective discomfort but able to return to work and function at pre-accident employment (or equivalent). +++: Total improvement.

Language: English Publication: full paper No additional information from authors For results, see the comparisons: 8.1 Conclusion: “The group that had been treated with needling was found to be clearly and significantly better than the control group with regard to status at discharge, at 12 weeks, and at final follow-up” He 1997 Methods Participants -Randomized (method not reported). No information about concealment of allocation -Patients were blinded -Funding: Not reported -Setting: outpatient clinic in a hospital. University Centre in Sichuan Province, China -Informed consent: Not reported -Ethics approval: Not reported -Follow-up: All 100 patients were followed. -Analysis: Not reported 100 patients with low-back pain (5 days to 6 months duration), with limited range of motion, and symptoms worse in cold and rainy weather Excluded: kidney or bone disease confirmed by urine test and X-ray Age range: 22 to 79 years old 44 males and 56 females Working status: not reported Previous treatments: not reported Interventions 1) Manual acupuncture with moxibustion plus Chinese herbal medicine. Two groups of points: 1) GV 4, BL 22 , Ashi-points. 2) BL23, GV 3 and Extra 9 (L3-L4). Moxibustion was used 2 to 3 times on the handle of the needles and needles were retained for 30 minutes. Treatments were given daily up to 10 treatments. Teh Chi sensation was obtained. Herbal formula was given daily. Randomized to this group: 50 Experience: unknown 2) Chinese herbal treatment alone. Randomized to this group: 50 Outcomes 1) Overall assessment that includes pain, physical function, sensitivity to weather change and return to work. According to this measure, patients are classified into: a) cured: no pain, return to normal life and work, remains normal at one-year follow-up; b) marked effective: pain is generally gone, but still feels uncomfortable in cold and damp weather; c) improved: pain is markedly relieved, still feels uncomfortable in cold and damp weather, but better than pretreatment Acupuncture and dry-needling for low back pain (Review) Copyright © 2011 The Cochrane Collaboration.
