Why Your Back Keeps Going Out — Your Body Is Still Guarding It

If your back “goes out” again and again, it is usually not because your back is weak. It is because your body keeps guarding it the same way.

Why does it keep coming back?

The first episode is frightening. The second one changes how you live. You hesitate before lifting a suitcase, you brace before putting on socks, and you plan a trip around your back. For many people, fear of the next episode narrows daily life more than the pain does.

That is not something you are imagining. Your body really is on guard.

Each time it returns, the pain-free gap can get shorter

What does your body do first?

When pain arrives, the body stiffens the area around it so that you stop moving and do no further damage. Over a few days, that is a clever response.

The problem is when the guarding lasts. The Five Osteopathic Models, a modern osteopathic textbook in our clinic library (Track B+), describes how an abnormal protective muscular posture, driven by pain signalling, leads to remodelling of the connective tissue itself — the texture of the tissue changes — and how the pattern can become chronic if that posture is maintained.

In other words, the body starts a protective shape as first aid. If the shape stays, the material gets rebuilt to fit it. It is a little like an arm that has been in a cast.

Three stages of guardingAfter sudden low back pain the body stiffens around the low back to protect it, and when that guarding lasts, the tissue itself adapts to the shape and it stays.

What keeps the loop turning?

The same book describes a pain–spasm–pain cycle. It hurts, so the muscle shortens; it is short, so you move less; you move less, so it hurts. That loop can keep turning long after whatever started it has healed. This is why trying to remember “the movement that did it” often leads nowhere.

The pain and tension loopPain leads to muscles tightening, tightening leads to less movement, and less movement leads back to pain. Shown as three ovals joined by arrows in a circle.PainLess movementMuscles tightenThe loop turns after the trigger is gone

What happens when the juggling runs out?

When one area stops moving well, other areas take on extra work. That is compensation. The Five Osteopathic Models reads an alternating, well-shared pattern of compensation as a sign of adaptation, and a non-alternating one as a loss of adaptive capacity, typically after repeated small loads. The same book reframes health not as being “normal” but as being able to change your response as the environment changes.

Read that way, a back that keeps flaring is less a broken back than a narrowed range of juggling.

What do we actually look at?

If we look only at the sore area, we stay inside that loop. The Five Osteopathic Models makes the same point: it is important not to focus exclusively on the symptomatic region.

Sota Omura, our co-director, is a licensed physical therapist whose background is post-stroke rehabilitation and lower-limb symptoms. For a back consultation, he works outward:

  • The low back itself — which movement hurts, and where the movement stops
  • Pelvis and hip — whether they are doing the back’s work for it
  • Feet and walking — how load reaches the back with every step
The order we lookIn a low back consultation we look at the low back itself, then the pelvis and hip, then the feet and the way you walk, widening the view step by step. Shown as three numbered boxes.Low back1Pelvis and hip2Feet and walking3From where it hurts to where the load comes from

What can you do this week?

  1. Move often, within the range that does not hurt. The choice is not rest or normal life; let the pain set the width of the range.
  2. Do not hold one position for more than 30 minutes. Shift, stand, walk a little. That is enough.
  3. Do not hold your breath when you lift. Holding your breath makes the area around the low back tighten more.
Widening your rangeAfter a flare of low back pain the choice is not only full rest or normal life. Using pain as the guide, the range widens in stages from rest to moving a little to ordinary daily life. Shown as a three-part band.RestMove a littleBack to normalWiden the range by how the pain feelsA guide for the days after a flare

  • Pain that started after a fall or an accident
  • A history of cancer, or a diagnosis of osteoporosis

Questions we are often asked

Is this something I will have to live with long term?

People often ask us, “does a back like this ever get better?” The acute pain of an episode usually settles over days to a few weeks. What often remains afterwards is the guarded shape, and that is what tends to meet the same situation again. Rather than stopping when the pain goes, check whether your range of movement has come back.

Should I rest, or should I keep moving?

For the first day or two, going easy is more comfortable. After that, staying lying down makes it harder to get your range back. Move a little at a time, within the range that does not hurt.

Why look at my feet when my back is the problem?

With every step, force from the ground travels through the ankle, knee and hip to the low back. If something along that route is not moving, the back does the extra work. Loosening the back alone leaves the same force arriving at the same place.

Do you speak English?

Yes. We see English-speaking residents and visitors regularly — see English-Speaking Osteopath in Kyoto and Osteopathy for Travellers & Expats. WhatsApp is usually the quickest way to reach us.
