Different frequencies of acupuncture treatment for chronic low back pain: An assessor-blinded pilot randomised controlled trial
Yuan J et al. - The compliance rate was 100% for each group. Some of the measurements were shown to be sensitive (VAS, RMDQ, MYMOP-2 Wellbeing). 66–330 participants would be required for a fully powered non-inferiority trial. The groups were balanced at baseline for LBP and demographic characteristics. There were no significant differences between the groups in terms of any of the outcomes, at each follow-up time point. It was notable however that the clinically important improvement in terms of pain, functional disability, quality of life, and SWT in both groups was achieved within the first two weeks, which was maintained at one year follow-up. It is feasible to conduct a main RCT, to compare different frequencies of acupuncture for LBP, using sensitive measurements. Also the trend for early clinically important improvement within a minimum of four measurements is worthy of further study. [more...]
