Final answer:
Individuals with lower cross syndrome typically exhibit forward head posture, a depressed sternum, rounded shoulders, an increased lumbar curve, and a forward sway of the upper femur.
Step-by-step explanation:
The typical postural changes observed in individuals with lower cross syndrome include a) Forward head posture, depressed sternum, rounded shoulders, increased lumbar curve (lordosis), forward sway of upper femur.
This posture is characterized by an anterior tilt of the pelvis, which enhances the lumbar curve also referred to as lordosis or swayback. Such postural changes typically arise due to imbalances in the muscles around the pelvis and lumbar region where weakened abdominal muscles and tight lower back muscles contribute to the exaggerated postural curve.
