muscle imbalances and the si joint

the sports hernia, if left alone, untreated, for a long time, can very easily lead to muscle imbalances in and around the pelvis.
as one of the keys to our cores, the transversalis muscle is injured and can go into spasm as a result. this in itself can cause a domino effect of muslce imblances which can lead to great pain and dysfuntions. without the t.a. muscle to help support your lumbar spine, other muscles must become hypertonic to take over. linked to the t.a. via fascial connections are the pelvic floor muscles, the quadratus lumborum, and the gluteals, not to mention the obliques and rectus in the abdomen.
sometimes this imbalance or imbalances can lead to issues with the sacroiliac joint. si joint dysfunction is common yet, like sports hernias, is often missed when coming to a diagnosis for pain near the joint itself as well as the hip, groin, lower back, buttock, and tailbone.
if the muscle imbalance that occurs locks up compartments such as psoas, the pelvis can rotate which can in turn affect the si joint. si joint dysfunction can be severely painful in itself, and probably cannot be permanently corrected without the treatment of existing sports hernia(s).
it should also be noted that trigger points left untreated can also lead to a viscious cycle where the shortened, tightened muscles can not be stretched or lengthened due to these painful trigger points. once these are addressed, the position of the si joint can be addressed.
