Muscles that spasm are a functional aspect of lower back disorders and cannot be “seen” on an MRI or X-ray (unless there is an antalgic list which would be evident on standing X-rays). Muscle spasms are typically a result of back disorders and not a cause. Muscles spasms are a result of instability as a protective mechanism or nerve irritation that induces the spasm.

There are rare insertional tendonitis issues (like tennis elbow of the back) such as ischial tuberosity tendonitis but in the erector spinae group (back muscles), this is exceedingly rare.
