What is the kinetic chain, and why is it important for your secondary disability claims?

What is the kinetic chain, and why should you become familiar with it? We'll dive into all of the details and break it down for you – but for starters, this engineering concept is used to describe human movement. Veterans typically experience higher physical demands during service, which can lead to conditions later in life.


By understanding the kinetic chain, you'll be better able to determine whether a condition should be filed as a direct service connection claim or a secondary service connected claim. Let's dive in:

What is the kinetic chain?


The concept of the kinetic chain (sometimes referred to as the kinematic chain) was introduced by a mechanical engineer named Franz Reuleaux back in 1875. In short, he said that all segments of the body are interconnected in a system where movement at one joint has an impact on other joints in the kinetic chain.


It sounds a bit complicated, but basically, all of our movements are connected. If you hurt your arm, it can lead to shoulder pain, and so on.


Why is understanding the kinetic chain important for your secondary disability claims?


With over 50% of military service members reporting at least one or more injuries per year, it's important to understand how one injured joint may begin to affect other parts of the body. A common example we see often is service-connected knee injuries causing back pain, which is a direct result of the kinetic chain.


At MRPY Professional Services, we see improperly filed claims often – which can cost you both time and money when trying to get the benefits you deserve. You should be aware of the differences between direct service connected claims and secondary service connected claims:


  • Direct service connected claims: These claims should be filed regarding any injury or illness that happened while a Veteran was serving.


  • Secondary service connected claims: These claims pertain to conditions that are not directly caused by military service, but are made worse by a service connected disability.


We can help you with medical evidence to file with your secondary disability claims and get results
