Conditions & Treatments - Lower Crossed Syndrome
Lower Crossed Syndrome (LCS), also
known as pelvic crossed syndrome, is described as a muscle
imbalance pattern that affects the lower kinetic chain which
includes the lumbopelvic hip complex, knee, and ankle (1, 2).
This syndrome can be found in individuals who sit for prolonged
periods, continuously perform tasks for extending periods of
time utilizing poor posture, or have been immobilized (1). It
can also be found in individuals who perform repetitive actions
such as running or jumping (1).
When treating patients with LCS the shortened muscles must be
restored before embarking on training of the weakened muscles.
This is based on Sherrington's Law of reciprocal inhibition
which states that when one muscle is shortened or tightened its
opposite muscle relaxes (2, 3).
