Pain and acupuncture

At World Congress of Pain held in Montréal, Canada, Acupuncture was featured in numerous presentations. Acupuncture was also spotlighted in the plenary session.

Neuroscientist Ji-sheng Han, director of the Neuroscience Research Institute at Peking University and founder of the Chinese Association for the Study of Pain talked about his new studies and perspective on evaluating acupuncture vs placebo:

Just inserting needles under the skin does not work, at least not in rats which are impervious to sham treatments that can nonetheless get results (placebo) in humans.

People even said that acupuncture is nothing but placebo, that’s because just touching the skin with a needle can also produce an analgesic effect.

In rats, acupuncture needles simply left in place got no results. Manually twisted needles provided relief and electrical manipulation produced the best pain suppression. If the needles are not moved, there is no analgesic effect. If you manipulate continuously, (pain relief) goes up gradually. And when you pull the needles out the effect goes down. These are clearcut results.

So, on top of the psychological or placebo effect, you have a real analgesic effect.

These days, Chinese patients get about 30 minutes of pre-surgery acupuncture to increase the effect of “acupuncture analgesia” during an operation.

Other Han studies, replicated at the University of Texas, suggest that the right method of needle manipulation and electric frequency also play a key role. Clinicians need better training because acupuncture methods are critical when treating different kinds of pain, for example so as not to aggravate existing pain.

Below are some of the abstracts discussed at the congress:
