A muscle knot is identified as latent if it is only painful to touch, whereas it is considered active if it is also painful at rest or during movement. Unlike an injury that regenerates over time, a muscle knot has nothing to regenerate because it is simply a state of being of the muscle, more precisely a contracted state. Thus, it can remain contracted indefinitely for months or years if nothing is done. In the meantime, the muscle knot gradually turns to fat, and if the person becomes more sedentary, the muscle also melts down [1]. Moreover, a muscle knot increases the risk of triggering a cramp during physical activity [2].
