An Upper Crossed Posture describes a muscular imbalance dysfunction where your chest, shoulder and neck muscles become tight and over active. These in turn switch off (inhibit) their opposite muscles which are the mid and lower trapezius muscles (back muscles) and deep neck flexors so these become under active and weak.
As seen in the picture; this results in an increased curve in the upper back (increased kyphosis), rounded shoulders and a forward head carriage.
This posture can cause upper back, shoulder and neck pain due to the increased strain put on the joints and muscular tightness. Furthermore, headaches are common and as the shoulders become more rounded they decrease the space within the shoulder joint causing shoulder pain. Jaw dysfunction can also result from the increased strain on surrounding musculature from the head moving into a forward head carriage.
