Question

What are the LIKELY effects of a shortened iliopsoas muscle on the spine?

A. Increased lumbar lordosis and spinal flexion
B. Posterior pelvic tilt and spinal extension
C. Increased lumbar lordosis and spinal extension
D. Anterior pelvic tilt and spinal flexion

Answer 1

A shortened iliopsoas muscle can result in increased lumbar lordosis and spinal extension. The option (A) is correct.

Step-by-step explanation:

A shortened iliopsoas muscle can have likely effects on the spine. It may cause an increased lumbar lordosis, which refers to an exaggerated inward curve of the lower spine. This can lead to spinal extension, where the spine is pulled back and arches.

The iliopsoas muscle group consists of the iliac and psoas major muscles. When this muscle group is shortened, it can create imbalances in the muscles surrounding the spine, affecting the alignment and movement of the spine. Therefore, option (A) is correct.
