What could indicate proper body alignment in a patient?

Proper body alignment in a patient is characterized by a natural curvature of the spine. This means that the spine maintains its normal anatomical curves: the cervical, thoracic, and lumbar regions have specific curves that contribute to overall posture and balance. When a patient's spine exhibits these natural curves, it reflects a well-aligned posture, reducing the risk of pain or injury.

In contrast, uneven shoulder height can indicate imbalances or postural issues, while a twisted pelvis position suggests misalignment that can lead to further complications. A high foot arch also does not pertain to overall body alignment in the context of spinal and postural health. Therefore, the presence of a natural spinal curvature is a key indicator of proper body alignment.
