If you keep up with the world of massage therapy, you will eventually notice that there are some new ideas and terms going around. Evidence based massage. Evidence based practice. Evidence informed practice. Science based medicine. What does it all mean?

When I went to massage school, much of what we were taught was based on tradition or what was perceived to be common sense. We did certain things in certain ways because... well, because that was the way we were taught to do them. Massage "improved circulation." We should drink a lot of water after a massage so it would "flush out toxins." It seemed to make sense, right?

My first introduction to the idea that science was beginning to contradict some of our dearly held beliefs came when an instructor told me that research had shown that massage did not, as was commonly 오피톡 claimed, reduce lactic acid in muscle tissue. We'd always been told that a buildup of lactic acid in the muscles was what caused soreness and that massage reduced its presence. People repeatedly experience that massage reduces muscles soreness. Therefore, massage must be reducing the presence of lactic acid, right?

When someone finally did some research, it turned out that, in fact, massage did not reduce the presence of lactic acid. How could this be? Did this mean what we'd been led to believe was wrong? Well, it's true that massage does decrease soreness in muscles. Apparently, though, it is not because of lactic acid. How does massage decrease soreness? We don't clearly understand how it happens but we do know that it does happen.

Although one of massage therapy's sacred cows had just been slain, I liked it that this particular instructor was paying attention to science and research and was more interested in understanding the truth of what was happening rather than defending a tradition that might not be supportable.

Shortly afterward I discovered Neuromuscular Therapy, sometimes referred to as Trigger Point Therapy, and the work of Travell and Simons. Drs. Travell and Simons spent many years documenting the phenomena of trigger points and writing the two volume set Myofascial Pain and Dysfunction: The Trigger Point Manual. Studying their work gave me the tools to work effectively with some common pain conditions. It also began to give me the knowledge and vocabulary to speak intelligently to physical therapists and medical doctors about my clients and their patients. It started me down the path of an evidence based practice, a path which I strive to follow to this day.

Evidenced based massage therapy is massage therapy founded on ideas and principles supported by evidence. There is scientific, documented evidence to support the existence of and treatment of trigger points. There is documented evidence that massage relieves muscle soreness and can alleviate anxiety and depression.

Many of the claims made and practices used by massage therapists are founded on tradition rather than evidence. Since there is not yet a large body of knowledge documenting the physiology of and effects of massage therapy, if we were only able to make statements strictly on the basis of scientific studies, we would be severely limited, indeed. Some people prefer the term evidence informed practice as more accurate. An evidence informed practice takes into consideration scientific evidence, clinical experience, and careful observation.

I assumed this reliance on tradition was primarily confined to the field of massage therapy and was surprised one day when I found a large display about evidence based medicine in the halls of St. Louis University Medical School. Apparently, even in conventional medicine, many procedures are done because that's the way they have always been done and are not necessarily supported by evidence that they are the best way or even effective.

In science, one always has to be open to new evidence and be willing to change your mind when confronted with new information that contradicts formerly held beliefs. Another one of massage therapists' dearly held beliefs was challenged last summer when researcher Christopher Moyer presented a paper that showed that massage therapy did not lower levels of the stress hormone cortisol nearly as much as had been previously thought and, in fact, its effect on cortisol may be negligible. I'm sure I was not the only massage therapist who was startled by this news. However, once I got over the initial shock, I examined the evidence he presented. It took awhile for me to understand but in the end it seemed that he had very good evidence to support his conclusions. Does this mean that massage does not "work?" Well, it's obvious that massage makes us feel better, we just don't know exactly why or how.
