63 patients with low back pain (LBP) were randomized to receive either therapist-selected non-thrust manipulation or prescriptively selected non-thrust manipulation. The purpose of this study was to compare the differences in clinical outcomes of the two techniques in a long term setting. Findings indicated no differences between the two non-thrust manipulation methods for pain, disability or patient acceptable symptom state scores after 6 months follow-up. However, the therapist-selected intervention was favoured in global rating of change scores compared to the prescriptive intervention.
