You may or may not have come across the principle of tensegrity, but I'm guessing that if you are involved in any sort of soft tissue treatment you will have discovered that sometimes the area that presents with pain or problems is not always the area that you need to treat.
Sometimes therapists are guilty of making these relationships sound way too mystical as if there's some sort of secret knowledge that reveals the true root of the problem. A more straightforward understanding simply points out that the soft tissues are are dynamic structure that works under load and tension. Tightness in ove muscle or group is bound to have an impact on other tissues and structures with which it has a connection. Tensegrity is just one way of describing these relationships.
Anyway, there are a couple of interesting articles about some recent studies that explore these principles at Optimum Sports Performance. Part 1 is here and part 2 is here.
