National Physical Therapy Examination (NPTE) Practice Exam

Which posture is most typical for a patient diagnosed with ankylosing spondylitis?

1. Posterior thoracic rib hump

2. Flattened lumbar curve, exaggerated thoracic curve

3. Excessive lumbar curve, flattened thoracic curve

4. Lateral curvature with fixed rotation

The correct answer is: Flattened lumbar curve, exaggerated thoracic curve

The most typical posture for a patient diagnosed with ankylosing spondylitis is characterized by a flattened lumbar curve and an exaggerated thoracic curve. This condition primarily affects the spinal column, leading to stiffness and fusion of the vertebrae over time. As the disease progresses, there is a noticeable loss of normal spinal curvature. The lumbar spine often becomes flattened due to the disease's effects on the lumbar region, which occurs as the inflammatory process leads to reduced mobility. The thoracic spine may exhibit an exaggerated curve, often described as a kyphotic posture, due to compensatory mechanisms as the body attempts to maintain an upright position despite the progressive spinal immobility. Understanding this posture helps clinicians in assessing and managing the implications of ankylosing spondylitis on physical function and mobility. Recognizing these typical postural changes is essential for developing targeted physical therapy interventions to improve posture and function in affected individuals.
