PRI Education Blog #1 - Let's Begin With Asymmetry

Updated: Dec 7, 2022

Human asymmetry is a positive aspect of our bodies because it facilitates human movement. Without being asymmetrical internally we wouldn't be able to move lymph, and fluid or have pressure control. However, the largest issue we see with human asymmetry is that people do not know how to manage it. With this, we can see sometimes overuse of specific muscle patterns may promote dysfunction if left unmanaged!โฃ

โฃAsymmetrical aspects of humans:

  • The ๐๐ข๐š๐ฉ๐ก๐ซ๐š๐ ๐ฆ includes a stronger, larger, and better-supported right leaflet, while the left side is less supported and smaller. This right side has more pull on the entire thorax.โฃ

  • The ๐Ÿ‘ ๐ฅ๐จ๐›๐ž๐ฌ ๐จ๐Ÿ ๐ฅ๐ฎ๐ง๐  on the right compared to the 2 lobes on the left, making us heavier on the right side of our bodiesโฃ. ๐Ÿซ

  • The ๐ฅ๐ข๐ฏ๐ž๐ซ which on average weighs 3lbs contributes to the over-lateralization to the right side.

  • The ๐ก๐ž๐š๐ซ๐ญ is on our left side and it keeps our left chest wall hyperinflated.

  • We have a ๐ฅ๐ž๐Ÿ๐ญ ๐›๐ซ๐š๐ข๐ง ๐๐จ๐ฆ๐ข๐ง๐š๐ง๐œ๐ž and ๐ซ๐ข๐ ๐ก๐ญ ๐ฏ๐ข๐ฌ๐ฎ๐š๐ฅ ๐Ÿ๐ข๐ž๐ฅ๐ ๐๐จ๐ฆ๐ข๐ง๐š๐ง๐œ๐ž which is a reason many of us have less left peripheral vision and right cortical dominance. โฃ ๐Ÿ‘€


Asymmetry is not an issue, however, our management can be! โฃ

Dive into the Diaphragm:

The diaphragm that we use for respiration is not equal from side to side, nor should it be looked at as one whole unit. We look at this as a left side & a right side which is also known as the term, ๐ก๐ž๐ฆ๐ข๐๐ข๐š๐ฉ๐ก๐ซ๐š๐ ๐ฆ. โฃ๐Ÿ˜ฒ The anatomical asymmetry stars with the crura of the right leaflet (hemidiaphragm) inserts onto three lumbar vertebrae L1โ€“3 - [although it has been seen to insert lower around L3/L4] while the left leaflet inserts higher into L1. โฃThe right crura is stronger and thicker in comparison to the left crura.



What is Posture & How Does Posture Relate?

Posture is a reflection of the โ€œpositionโ€ of many systems that are regulated, determined, and created through limited functional patterns. These patterns reflect our ability and inability to breathe, rotate and rest symmetrically. Certain imbalances or asymmetry in our bodies may cause us to fall into patterns that negatively impact our muscles and alignment

How does PRI help?

PRI treatment is first used to identify and then correct typical patterns found in human bodies. PRI clinicians work to help give the body sensory input in order to influence our breathing and walking cycle which of course can help decrease sympathetic tone and chronic pain. The balance of our muscles, bones & joints can influence how we stand, walk, breathe, think, sleep & regulate our bodies. We address these underlying postural asymmetries and restore alternating and reciprocal motion via balancing breathing patterns and tapping into our nervous system. PRI integrates the respiratory system, the nervous system, the muscular system, the skeletal system, grounding via arch and heel support, dental occlusion & visual system. PRI-trained clinicians to understand the direct relationship that these professions have on postural alignment which can affect everything when it comes to control and sense within one's body.
