Effect Modifiers of Graded Sensorimotor Retraining for Chronic Low Back Pain

Which variables modify the effect of graded sensorimotor retraining on pain intensity and disability level at 18 weeks and 52 weeks of follow-up?In this secondary analysis of a randomized clinical trial involving 276 participants, there was limited evidence of treatment effect modification by the 8 baseline variables identified. Back perception was identified as a potential treatment effect modifier for pain intensity at the 52-week follow-up time point.These findings suggest that the benefits of graded sensorimotor retraining may be similar for all people with chronic low back pain, regardless of individual differences at baseline.
