Postural refers to a person's physical position or stance, particularly in relation to their spinal alignment and overall body mechanics. It can also refer to the way someone holds themselves or carries their body while standing or sitting, which may indicate certain habits or tendencies related to posture. In medical contexts, "postural" is often used to describe abnormalities in a person's posture that may be caused by factors such as muscle imbalances, joint issues, or neurological conditions.
