🔥 REGIONAL INTERDEPENDENCE – KINETIC CHAIN
👇 Regional interdependence is a concept that unrelated impairments in the bodies kinetics chain can affect regions beyond themselves. However, this theory can be super complex and often overstretch its merit. For most people the important thing to take away from it is the joint by joint concept. This concept tells us certain joints require good deal of stability while others a large degree of ROM.
✅ We can think of it this way, your stable joints require a strong musculature around them to create a stable base of support for the mobile joints to move on, therefore they follow a order of stable, mobile. Think of the a complex of a stable joint and a mobile joint as a large crane, The cranes boom is able to travel in all directions and interact with object while the base is very strong heavy and only moves slightly. If we take that stable base away now the boom must limit its ROM to provide more stability, or vice versa the base must start to compensate to allow the boom to make its full movement. This can be the case for our joints as well stable joints compensate for the lack of ROM of motion of mobile joints which can alter movement patterns and cause certain muscles to weaken.
🚨 Our bodies kinetic chain goes as follows, High mobility at the ankle, stability at the knee, mobility at the hip, stability at the low back, mobility at the thoracic spine, stability at the cervical, as for the shoulder blade it requires a high degree of stability and higher degree of mobility to function well with the shoulder joint.
🚨 This concept explains my previous post on why the lack of hip mobility can lead to increase lumbar mobility. The main thing to take away is when training for mobility at joints work on the stability in the preceding joints
