The Full Spectrum of Muscle Function

Muscles move bones and allow us to use our body for standing, walking, running, and every other physical action. Muscles can and will take on many different degrees of function and, when they don’t work properly, it creates dysfunction. In general, the full spectrum of muscle function can range from very loose muscles (gross weakness) with no perceivable contraction to the other extreme of hypertonic or very tight, spastic muscles. Between these two extremes are a number of other important states.
