Document Summary
Relative alignment of various segments of the body with one another. Normal alignment: balanced front to back, side to side: pathologic is imbalanced. Sagittal plane: line of gravity; side to side, sagittal side, passes right through ear, acromion, greater trochanter, anterior to knee, anterior to ankle joint. Places abnormal stress on kinetic chain: bicycle chain: one link affects the next, compensation up or down the kinetic chain. Causes; occupation, sport, disease, age, injury, habit. A lengthened muscle over time will become weak. Tissues not designed to be stretched for prolonged periods. Excessive lumbar lordosis: pelvis tilted anteriorly, gluteus is tilted superiorly, hip flexors and back extensors are shortened, abdominals, glutes, and hamstrings are lengthened, can lead to narrowing of ivf: where nerves exit. Decreased lumbar lordosis: abs are shortened; glutes are shortened, spinal extensors are lengthened, reduces the spine"s ability to absorb shock.
