Why does physical therapy sometimes fail for lumbar instability — even when you do the exercises, show up consistently, and put in the work?

In this Vertrae® 360 Short Deep Dive, we explain why lumbar instability is not always a simple “weak core” problem. Standard physical therapy often focuses on general strengthening, but instability usually requires a more specific approach that targets the deep stabilizing muscles of the spine, especially the multifidus and transversus abdominis.

You’ll learn why traditional core exercises like crunches, planks, or generic back-strengthening routines may not fully restore spinal control when the multifidus has become inhibited by chronic pain or injury. We also discuss why stability-directed therapy must focus on timing, coordination, endurance, and neuromuscular control — not just strength.

For some patients, the deep stabilizing system does not respond enough to voluntary exercise alone. In those cases, options like ReActiv8® restorative neurostimulation may be considered to help activate and retrain the multifidus muscle. When structural instability is more advanced, additional treatments may be needed.

At Vertrae® in Dayton, Ohio, Dr. Kamal Woods evaluates lumbar instability by looking at symptoms, imaging, movement patterns, function, and patient goals to determine which treatment path makes the most sense.
