Postural Restoration is a unique, non-traditional approach to physical medicine and rehabilitation that focuses on identifying and treating mechanical imbalances within the body. This methodology views the body’s posture and movement patterns as being driven by a complex interplay of neurological and mechanical systems. The ultimate goal is to address the underlying patterned movement that leads to chronic strain and dysfunction, rather than simply treating the location of pain.
Defining Postural Restoration
Postural Restoration (PRI) is a methodology that seeks to restore proper movement and alignment by addressing the body’s inherent neurological and mechanical patterns. It recognizes that chronic pain and movement limitations are frequently the result of the body becoming “stuck” in a patterned position, which leads to overuse of certain muscle groups. PRI focuses on re-establishing a foundational state of balance.
The primary objective of this treatment is to achieve “neurological neutrality.” This state signifies a body capable of utilizing both its left and right sides equally for support and movement, rather than relying on one dominant side. Restoring this neutrality allows for reciprocal function, which is the body’s ability to alternate between the left and right sides smoothly and independently, such as during walking or running.
Understanding Human Asymmetry
The foundational concept of Postural Restoration is that the human body is not symmetrical, which creates natural biases in posture and movement. Anatomical structures, such as the liver, located primarily on the right side, directly influence the position of the diaphragm and the rib cage. Furthermore, the right lung has three lobes while the left lung only has two, making the right side structurally larger and heavier.
This inherent asymmetry means that the body naturally favors a certain mechanical pattern, typically one of weight-bearing on the right leg while simultaneously moving the torso into a slight rotation to the left. This patterned preference is normal and facilitates efficient movement, but when it becomes fixed or exaggerated, it leads to chronic strain. When the body cannot easily shift out of this dominant pattern, certain muscle chains become chronically short and tight while their counterparts on the opposite side become long and inhibited.
This fixed position causes predictable compensations throughout the entire system, leading to joint compression, muscle overactivity, and a reduced range of motion. For example, the constant right-side weight shift can result in the pelvis rotating forward on the left and the lower back compensating by extending excessively. These pathological patterns make the body unable to perform reciprocal movements without pain or limited range.
Restoring Neutrality Through Respiration
The mechanism for breaking these fixed patterns centers on the diaphragm and the power of respiration, as the diaphragm is both the primary breathing muscle and a major postural stabilizer. Due to the body’s structural asymmetry, the right diaphragm tends to be stronger and in a mechanically advantageous position because of the structural support provided by the liver beneath it. This imbalance often results in a decreased “Zone of Apposition” (ZOA) on the left side, which is the area where the diaphragm attaches to the inner wall of the lower rib cage.
A reduced ZOA compromises the diaphragm’s ability to function optimally, forcing the body to use accessory muscles in the neck and chest for breathing. This leads to an elevated, externally rotated rib cage, which locks the trunk into the non-neutral, patterned position. To restore the ZOA and reposition the rib cage, PRI utilizes specific, targeted breathing techniques, often involving a balloon or a particular body position like the 90/90 hip lift.
These exercises promote an elongated exhalation, which forces the recruitment of the abdominal muscles, particularly the internal obliques. The contraction of the internal obliques pulls the rib cage down and into internal rotation, mechanically repositioning the pelvis and spine toward a neutral alignment. This process re-establishes the diaphragm’s proper dome shape, allowing it to function as a respiratory muscle without also having to act as a primary postural stabilizer. This breathing also helps shift the nervous system from a sympathetic “fight-or-flight” state to a more relaxed, parasympathetic state, necessary for the body to accept a new position.
Conditions Addressed and Treatment Focus
Postural Restoration treats a wide range of conditions, extending beyond general musculoskeletal pain to include chronic issues linked to compensatory movement patterns. Common problems addressed include persistent low back pain, chronic headaches, and temporomandibular joint (TMJ) dysfunction, often connected to neck and rib cage positioning. Gait abnormalities, such as over-pronation or a lack of arm swing, and performance limitations in athletes are also frequent targets of treatment.
The focus of the treatment is highly individualized, as the therapist must first determine the unique way a person’s body is compensating for its natural asymmetry. A typical session integrates manual techniques to temporarily release overactive muscles with specific non-traditional exercises that use respiration to neurologically reposition the body segments. Patients are taught how to integrate this newly established neutral posture into everyday activities, ensuring the brain learns to access the full range of motion necessary for reciprocal function. The long-term goal is not just to reduce pain, but to allow the individual to move efficiently and symmetrically without defaulting back to their old, patterned compensations.
