title: An international expert survey on acupuncture in randomized controlled trials for low back pain and a validation of the low back pain acupuncture score.
abstract: BACKGROUND
  Acupuncture is a promising treatment approach in patients with chronic low back pain (cLBP) but little is known about the quality of acupuncture in randomized controlled trials (RCT) of acupuncture cLBP. -
  
  
  OBJECTIVE
  To determine how international experts (IES) rate the quality of acupuncture in RCTs of cLBP; independent international validation of the Low Back Pain Acupuncture Score (LBPAS).
  
  
  METHODS
  Fifteen experts from 9 different countries outside China were surveyed (IES). They were asked to read anonymized excerpts of 24 RCTs of cLBP and answer a three-item questionnaire on how the method of acupuncture conformed to 1) Chinese textbook standards, 2) the expert?s personally preferred style, and 3) how acupuncture is performed in the expert?s country. Likert scale rating, calculation of the mode for each answer, and Spearman?s rank correlation coefficient between all three answers and the LBPAS were calculated.
  
  
  RESULTS
  On comparison with Chinese textbook standards (question 1), 6 RCTs received a good rating, 8 trials a fair and 10 trials a poor or very poor rating. 5 of the 6 trials rated good, received at least a good rating also in question 2 or 3. We found a high correlation of 0.85 (p<0.0001) between the IES and LBPAS ratings for question 1 and question 2, and a correlation of 0.66 (p<0.0001) for question 3.
  
  
  CONCLUSIONS
  The international expert survey (IES) revealed that only 6 out of 24 (25%) RCTs of acupuncture for cLBP were rated "good" in respect to Chinese textbook acupuncture standards. There were only small differences in how the acupuncture quality was rated in comparison to Chinese textbook acupuncture, personally preferred and local styles of acupuncture. The rating showed a high correlation with the Low Back Pain Acupuncture Score LBPAS.
