Why does back pain or sciatic pain keep coming back, even after exercise and therapy? That question stops many people mid-scroll.It also stopped university researchers.Because pain often returns without warning.Even when scans look normal.Even when exercises are done correctly. So researchers looked deeper.Not at nerves first.But at hidden spine muscles. These muscles sit deep near the spine.They control tiny movements between bones.They protect nerves from excess motion. When pain lasts long, these muscles switch off.Exercise cannot always turn them back on.Many people cannot feel them working. Researchers tested electrical muscle stimulation.They watched muscles activate using ultrasound.No guessing. Real images. Deep spine muscles activated during stimulation.Some activated for the first time in years.Best results happened when abdomen and back were stimulated together. This study does not promise pain relief.It does not claim treatment or cure.It explains why instability can remain. When deep muscles stop helping,the spine becomes harder to control.And nerves become easier to irritate. This helps explain recurring back pain.It also helps explain sciatic-type pain.
