I was pleased to see that a group of researchers from Manchester in England (that's its skyline, above!) did a double-bind randomized controlled study of twenty seven people suffering from temporomandibular joint myofascial pain (TMJ/MP), to see if acupuncture would help them.
The people in the trial either had acupuncture or something called "sham" acupuncture, using a device that was created to create a "placebo control." The piece of equipment is called the Park Sham Device, and there has been a lot of discussion about whether it is really feasible to do "pretend" acupuncture. This study showed that it is.
The acupuncture was shown to have a greater influence on pain and movement than the "sham" treatment.
This is important: TMJ can be very difficult to treat. Last year there was a report, also from the UK, that acupuncture seemed to be effective, based on an audit of dental practices, and this study just adds to the evidence that we are accumulating.
