I’m pleased to announce that 30 healthy volunteers have been successfully recruited signally the completion of the recruitment phase of the study. Healthy volunteers received low-dose quantitative fluoroscopy (OSMIA) to measure the movement of their neck vertebrae at baseline and four weeks later. This will let me estimate how much inter-vertebral motion might vary over time in people with no neck pain receiving no treatment. Any motion changes observed in patients receiving spinal manipulation will need to be larger than any changes that occur in the healthy volunteer group for there to be any suggestion of association with the treatment. We’ll know soon – watch this space!
