Question

What is the effect of Nutation on the Lumbar Spine?

1) Increases flexibility of the lumbar spine
2) Decreases flexibility of the lumbar spine
3) Has no effect on the flexibility of the lumbar spine
4) Cannot be determined

Answer 1

Nutation typically decreases the flexibility of the lumbar spine by increasing the natural lordotic curvature and stabilizing the lumbo-pelvic region.

Step-by-step explanation:

What is the effect of Nutation on the Lumbar Spine? This question pertains to the biomechanics and function of the lumbar spine. Nutation is a movement at the sacroiliac joint, which is where the spine and the pelvis meet. Nutation involves a slight forward movement of the sacrum in relation to the ilium and is accompanied by an increase in the natural lordotic curvature of the lumbar spine, which can result in a relative decrease in the flexibility of this spinal region. In answer to the question, nutation typically decreases flexibility of the lumbar spine because it stabilizes the lumbo-pelvic region and reduces motion between the vertebrae.
