Upper cross syndrome and lower cross syndrome are terms heard within the world of medicine that, on the surface, sound a little intimidating. However, each term simply refers to muscle weakness and tightness in certain areas of the body that may be contributing to pain and/or reduced functional level. Each “syndrome” entails two predominant areas of muscle tightness and two predominant areas of muscle weakness. Often times, these limitations occur as a result of impaired posture and can lead to pain. Once identified, both upper cross and lower cross syndromes can be effectively treated and managed with physical therapy care.
