Looking at the joints in the body.

Looking at the joints in the body, every other joint is predominantly built for either mobility or stability. This is an important concept to understand when you are looking at the body as a whole.

All joints have the capacity of both stability and mobility. But each joints predominant function is either one or the other.

Predominately mobile jointsare multidirectional and have lots of range of motion. They go in many different directions for example the hip joint does: Flexion, extension, adduction, abduction, internal rotation and external rotation.

Predominately stable joints have 2 main directions. For example the knee does flexion and extension really well.

If you lose mobility in a joint, another area in the body will have to pick up the slack. And same for if you lose stability in a stable joint, another area in the body will be forced to pick up the slack. If a joint is doing it’s job and the job of another, this will be a great spot for an injury to occur.
