These findings of altered movement and glide support the concept that altered mechanics of the sacroiliac joint are correlated with the presence of pain.
The spine is an incredible structure, with both great stability but also tremendous mobility in all three cardinal planes.
Motion palpation assessment is performed by bringing the client’s joint to the end of its passive ROM and then gently applying a small, even, steady force.
The lumbosacral spine should have a healthy anterior pelvic tilt and lumbar lordosis. If they are excessive, the client has lower crossed syndrome.
Spondylolisthesis is a condition of the spine in which one vertebra slips on the vertebra below it. This condition usually occurs in the lumbar spine.
Sprains and strains are similar in nature. When a ligament or joint capsule is torn, it is termed a sprain; when a muscle is torn, it is termed a strain.
The two most common causes of a hypomobile joint dysfunction are tight muscles, especially smaller, deeper intrinsic muscles, and fibrous adhesions.
Four of the most common causes of tight muscles of the low back (or anywhere in the body) are: overuse, splinting, adaptive shortening, and overstretching.
The “action” of a ligament is similar to that of an antagonist muscle. If either is tight/taut, it restricts motion to the opposite side.
Structural groups of muscles largely determine functional groups—that is, the structural location of a muscle largely determines its mover function.
