PHYSICAL THERAPY FOR BACK PAIN
Physical therapy fails most often when nobody established what it was supposed to be treating.
It is the most evidence-supported treatment in this field and the one most often written off. Almost always the problem is not the therapy; it is that it was aimed at a back rather than at a mechanism.
Why generic programs disappoint
A back driven by facet loading in extension and a back driven by a disc under flexion need opposite programs. Give both the same generic core protocol and one improves, one worsens, and the average across a clinic looks like modest benefit.
That averaging is a large part of why the literature on physical therapy for back pain looks lukewarm. Programs matched to a mechanism perform considerably better than programs matched to a diagnosis code.
Matching the program to the pattern
EXTENSION-INTOLERANT (FACET, STENOSIS)
Worse standing and walking, better sitting. Flexion-biased work, hip extensor and deep abdominal strengthening, graded walking with seated breaks before symptoms build. Avoid end-range extension early. Stenosis u00b7 Facet syndrome.
FLEXION-INTOLERANT (DISCOGENIC)
Worse sitting and bending, better standing. Extension-biased loading, hip hinge retraining so the lumbar spine stops absorbing the movement, and breaking up sitting duration. When sitting is the problem.
INSTABILITY OR SACROILIAC PATTERN
Force-closure work across the pelvis — deep abdominal wall, gluteals, pelvic floor — rather than general stretching, which often makes a hypermobile pelvis worse. The SI joint.
What good therapy looks like
- An assessment that produces a directional preference, not just a list of exercises.
- Progressive loading with measurable increments. Tissue adapts to demand; unchanging exercises stop producing change.
- Homework that is short enough to actually happen most days, rather than a forty-minute program done twice.
- Re-assessment at three to four weeks, with the program changed if function has not moved.
- An endpoint. Therapy should hand you a maintenance program, not continue indefinitely.
Where interventional treatment fits alongside it
These are not competing options and treating them as such is the usual mistake. When pain is severe enough that a person cannot perform the loading that would help, the therapy fails for mechanical reasons rather than clinical ones. That is exactly the situation where a confirmed, targeted procedure earns its place: it quiets the signal enough for the work to become possible.
The injection is not the treatment. It is what makes the treatment possible, and the treatment is largely this page.
Common questions
How long before physical therapy works?
Expect some directional signal within three to four weeks. No change by then means the program should be reconsidered rather than continued.
Is it normal for it to hurt?
Mild soreness that settles within a day is expected. Pain that increases session over session, or that starts traveling down the leg, means the direction is wrong.
Can I just do exercises from the internet?
You can, and it works for the people whose pattern happens to match the video. The value of an assessment is knowing which of the two opposite programs is yours. The type of exercise matters far less than that it happens.

Ask what direction your back prefers before you start
If nobody has established that, the program is a coin toss and you have a fifty percent chance of doing the wrong one diligently.
