What is characterized by excessive lordosis?

1. Swayback or an increase in secondary curvature

2. Hunchback or an increase in primary curvature

3. Flat back or lack of curvature

4. Abnormal lateral curvature of the spine

The correct answer is: Swayback or an increase in secondary curvature

Excessive lordosis is defined as an abnormal increase in the curvature of the lumbar spine, leading to a pronounced inward curve. This condition, often referred to as "swayback," highlights an increase in secondary curvature, which is the natural curve of the spine in the lumbar region developed after infancy as a person begins to walk upright. Understanding this, the condition typically results in postural issues and may be associated with factors such as obesity, poor posture, or muscular imbalances, which can further exacerbate the curvature. The excessive curvature can result in discomfort, pain, and potential functional limitations in movement, as well as aesthetic changes in posture. The other answer choices do not accurately describe excessive lordosis: hunchback refers to excessive kyphosis (an increase in primary curvature), flat back indicates a decreased or absent curvature, and abnormal lateral curvature of the spine is known as scoliosis. Each of these terms relates to different spinal alignment issues that do not align with the characteristics of lordosis. Thus, the correct identification of excessive lordosis as swayback is essential for understanding postural deviations and their implications in fitness and rehabilitation contexts.
