Iliopsoas caused a herniated disc?

[HeMB]

From The Evolved Athlete: A Guide for Elite Sport Enhancement

When the iliopsoas is overworked, or too weak to handle the stress imposed on it, it can go into spasm or tears in the muscle may leave scar tissue causing pain and weakness. This can cause many of the surrounding muscles to compensate and become tight and painful as well. These muscles can pull the spine out of alignment and may lead to disc herniation, usually at the L4-L5 level.

I am wondering, if tight/weak iliopsoas could cause me a herniated disc?

Maybe somebody could bring some further insight regarding this and also about " This can cause many of the surrounding muscles to compensate" ? More specifically, what could be those muscles?

Overall, it seems plausible because iliopsoas connects to all of the lumbar vertebrae. Unfortunately, there's very little about that online.

It is unlikely for you to get a herniated disc from this to my knowledge. I wouldn't really worry about this if you are not currently having pain. Here's some related reading you may be interested in: https://jaoa.org/article.aspx?articleid=2094465

Yes. A tight psoas major can force Hyperlordosis (duck butt) and put a huge strain on lower lumbars. This person will have a weak rectus abdominis and hamstrings while having tight erector spine muscles that are trying to compensate. If you think you have a tight PM go to a sports massage therapist and have them help you stretch that muscle. Here is a video that I made just for this condition. Its for massage therapists but you will get the point. https://youtu.be/WH1aj73xXpQ

But the mechanism of herniation is flexion.

Should not hyperlordosis actually help in that regeard?

Actually I am having pain but it's due to a confirmed herniated disc.

The reason of what I am asking here is that I can hardly grasp the root cause of the herniation.
I have never lifted anything heavy with full flexion and rarely with slight flexion. That's a paradox really.
Hence I am looking for some alternate reason, muscle imbalances causing bone alignment issues or so.

In addition, the MRI report I had said that I have straightened physiological lordosis.
It indicates psoas actually being weak, not hypertonic... Any thoughts?

It's really hard to determine the root cause of something that likely built up over an extended period of time. Truthfully I'm not knowledgeable enough to try to posit a cause for you. Have you seen a specialist of some sort?

Yes, I have seen. Besides suggesting general core strengthening, he did nothing more ( though the exercises were decent).

HeMB. In your original post you said your psoas was tight. A tight psoas muscle is in flexion. That is why your doctor wants you to strengthen your core (abs). Your rectus abdominus is what counters the psoas major.
