According to Dr. Robert Boyd D.O, everyone, including athletes is compromised with
asymmetrical patterning that is a result of pre-birthing and or birthing trauma, representing apredisposing cause, he also observed that there are precipitating factors such as injuries, overuse, misuse, which will affect the function of the primary respiratory
mechanism and beyond.
A very simple way to validate this is to observe each athletes cranio-facial landmarks, which will result in one ear, temporalis bone being superior to the other and one ear being more anterior than the other, one maxilla will be superior and one inferior, the mandible will display the same effects with one side being superior and one inferior, this would also include the orbits, occipital bone, etc.
According to Dr. Boyd the spine follows the cranium and not the other way around,
and if this is actually true, then it will be extremely difficult to correct cervical
compensations. When the occipital bone as well as dural components impose there
force upon C1 keeping it rotated and side bent in a particular vector of force, what ever
you do to the cervical vertebra will be limited or temporary because the descending
pattern has not been corrected, and as a result of this descending force, pelvic rotation will also take place producing an ascending pattern resulting in a leg length differential which will wreak havoc throughout the entire musculo-skeletal structure, causing certain muscles to be overstretched and weak, and others to be over tight and contracted, from right to left, front to back and obliquely with various vectors of compensation.
When considering the pelvic landmarks, each athlete will display one iliac crest that is
superior and one inferior, as well as one ASIS will be more anterior and one posterior. The functional aspect regarding the leg length of each athlete will also be affected with one leg being short and one long.
We could simply conclude that there are ascending and descending pattens are
affecting the overall function and performance of every athlete in the world today. It is interesting to note that as a result asymmetrical patterning as it relates to the soft tissue matrix (muscles, ligaments, tendons and fascia) and the discontinuous
compression elements [bones] and CNS, each athlete will have up to a 50% reduction
in overall strength regarding the major muscle groups crossing over a joint complex, this will negatively affect their ability to produce optimally functional contractile forces when engaged in athletic endeavors.
Asymmetrical patterning could be likened to a wrestling opponent that continues to increase in strength as time passes creating greater resistance to our movement and performance potential!
