Authors recognize their primary limitation of inactive intervention for controls.

The control group is not a control at all. It is well known that personal intervention will almost always cause patients to perceive benefits. This study reaffirms that observation and says nothing about the efficacy of the CAM treatment, which is probably nothing, since there is no known mechanism by which it would work. Also, most of their compliance data were self-reported, which is known to be highly unreliable.
