The MDs did not perform the acupuncture. Professional acupuncturists performed the treatment, and then independent researchers (again, not the MDs)
interviewed the patients after each treatment session. This is how a typical double-blind study is performed as a means of reducing investigator and
subject biases.
I doubt you are the only MD with that bias. It could be completely possible that the persons involved in that study share your bias. However, your
bias could be the cause of your inability to accept the idea of anything "mystical".
Again, please show me how the investigators bias would have affected this study, given that the MDs did not perform the acupuncture or interview the
patients. The only thing the MDs did was design the basic experiment and then collect/publish the data. They even mentioned in the conclusion that
chronic acupuncture use *might* be helpful, but they haven't studied it thoroughly enough for a long enough time frame, yet.
I would suggest that sham acupuncture does not determine "the effect of doing nothing". It seems that it might possibly determine "the effect of
doing something dangerous". Do you "ALWAYS" have to have a "negative" control, or can you just get away with a control group?
A control group IS a negative control. If I'm testing a drug in rats, I would give group 1 the experimental drug (experimental group), group 2 a
sugar pill or saline injection (control group, negative control), and if I wanted to be extra thorough, I would give group 3 a known successful agent
(control group, positive control).
The sham acupuncture was included to factor placebo effects out of the results of actual acupuncture. The idea is that if, say, 75% of people in the
actual acupuncture group reported pain relief, while 25% in the sham acupuncture group (which they wouldn't know was actually sham acupuncture)
reported pain relief, then you could ostensibly attribute 25% of the actual acupuncture's pain relief to placebo effect, meaning only an estimated
50% of actual acupuncture patients experienced pain relief attributable to acupuncture. Of course, in this study, the sham acupuncture group showed a
HIGHER rate of pain relief, which casts doubt on acupuncture having any effect other than the placebo effect.
