"How in the world is that still an issue? It has been months since that injury!"
This is a common response when one of my staff discovers an area of tenderness and sensitivity that a client assumed was no longer an issue. How indeed does something linger in the background for so long, only to be revealed when one of the BWA staff thoroughly explores the area?
There are some reasonable explanations for this based on the current understanding of muscle function. (Current understanding because what we know is always changing based on the research in the field.) The most plausible explanation is that when the muscle is first injured, it increases its electrical activity and is often noticeably painful. Once the initial insult quiets down, there is still remains an increase in activity and sensitivity. This increased activity is no longer perceived as a threat by the nervous system because the intensity does not change over time. The nervous system relegates it to the background since there are far more pressing issues to attend to.
But, just like in a computer, running programs in the background still takes energy and "bandwidth". When one of my staff finds such an area, the brain is now reminded again of the injury. In essence, our hands stimulate the brain to reassess the area. Our hands ask the question, "Did you know about that? Do you still want to keep it?" The brain then reassesses the area based on current, rather than historical information. As you have probably experienced, the result is often a decrease in pain and an increase in function. This also explains why clients report an increase in energy and well-being a day or so after a session. With less energy being funneled to areas of restriction, there is more available energy to allot to the demands of daily life!
