Assess the Entire Body

When dealing with chronic pain or persistent movement issues, it is easy to focus on the place where the symptoms appear. The shoulder hurts, so we assess the shoulder. The knee hurts, so we examine the knee. But the body rarely operates in isolated parts. Human movement is an expression of the entire system, and chronic issues often require us to look beyond the location of the symptom to understand what the body is actually responding to. Check out this week’s Zelos Podcast for more insight on this topic.

At the center of this process is the brain. Every movement is influenced by how the nervous system interprets the information it receives from the environment and from within the body. That information is constantly being compared against the brain’s primary objective: survival. From a primal perspective, two fundamental threats dominate that objective—starvation and being attacked or eaten by a predator. While modern life presents very different challenges, the nervous system still evaluates incoming information through the lens of safety and threat.

When the brain perceives a potential threat, it may alter movement strategies to protect the individual. These changes are not necessarily conscious decisions. They can manifest as changes in posture, balance, joint motion, breathing, gait, or how the body distributes mass. Over time, a strategy that initially helped the body feel more secure can become a persistent compensation. The result may be pain or dysfunction somewhere seemingly unrelated to the original driver.

This is why assessing the whole body is so important when addressing chronic issues. Rather than simply asking, “Where does it hurt?” we should also ask, “What information is the brain receiving, and how is the body responding to it?” Examining resting posture, gait, balance, visual and vestibular input, joint motion, and the body’s ability to manage mass in all three planes can provide valuable clues about why a particular movement strategy has developed.

The goal isn’t simply to treat the symptom or force the body into a predetermined position. It is to understand the strategy, identify the information influencing it, and provide the nervous system with better options. When we assess the whole person rather than isolating the painful body part, we have a greater opportunity to restore movement toward center, reduce unnecessary compensation, and help the individual build a more adaptable and resilient system.
