Stability and Mobility design of the Human Body

​All body movement involves a combination of joint mobility and stability through joints that are controlled by muscles which themselves are under the control of the nerve system. The anatomical arrangement of joints in the human body is in an alternating pattern to allow joints to be stable as mobility occurs. This arrangement is true from the feet to the top of the head and from the neck to the fingers. 

What are Stable Joints? 

The role of stabile joints is to keep one part of the body secure whilst other segments move safely through their proper range of movement. If a stable joint fails, you will often experience pain and dysfunction elsewhere in the body. 

What are Mobile Joints? 

Mobility of a joint is determined by its ability to have a normal/good range of motion through all six degrees of movement. A common example of a mobile joint losing part or all of its ability to move through all six degrees of movement is the hip. Due to sedentary lifestyles, the hip losses its mobility and the extra workload is transferred to the lower back structures. Over time, the overloading of the lower back joints get irritated and present as lower back pain.

The take home message is when a stable joint loses stability and/or a mobile joint loses mobility, problems will occur elsewhere in the body. Commonly, problems show themselves through pain and discomfort in joints away from the joints that have lost either their mobility or stability. The skill of a good therapist is to find where the kinetic chain has broken down in mobility, stability, or both and correct the cause of pain.
