Question

If scapular adductions are weak, the postural deviation called _____ is likely.

A. Scoliosis
B. Lordosis
C. Sway back
D. Kyphosis

Answer 1

Weak scapular adductions are likely to result in the postural deviation known as kyphosis, an excessive posterior curvature of the thoracic spine.

Step-by-step explanation:

If scapular adductions are weak, the postural deviation called kyphosis is likely. Kyphosis is defined as an excessive posterior curvature of the thoracic region of the vertebral column, often referred to as humpback or hunchback. One way this condition can develop is when osteoporosis causes weakening and erosion of the anterior portions of the upper thoracic vertebrae. This leads to their gradual collapse and results in an excessive curvature of the spine.
