Why balance training has to progress
A fixed-difficulty balance tool is only correct for one moment in someone's recovery. Everything before that moment is unsafe, and everything after it is a waste of the session.
Most balance equipment has one setting. A wobble board tilts as far as it tilts. A foam pad compresses as much as it compresses. The difficulty is a property of the object, decided at the factory, and it never changes.
That is fine if the person standing on it happens to match that difficulty. The trouble is that nobody matches it for very long.
The window problem
Someone three weeks out from an ankle reconstruction and someone training for a return to sport are not doing the same task, even if the goal on the chart says "single-leg stance" for both. A tool set at one difficulty serves exactly one point on that path.
Before that point, the tool is too hard. The person compensates — grabs a rail, locks a knee, shifts the work somewhere it wasn't meant to go — and you are no longer training what you set out to train.
After that point, the tool is too easy. The session still happens, the box still gets ticked, and the stimulus that produced the improvement is gone.
The usual answer is to own three tools and step between them. That works, and it means the progression happens in jumps: the person is on the wrong side of a gap until the day they can clear it.
What continuous adjustment changes
BALEROboard sets its firmness by air volume. Less air means a softer, less stable surface; more air means a firmer, more predictable one. It is a dial, not a set of steps, and the range is continuous between the ends.
Two things follow from that, and they are worth separating from anything clinical:
- The increment can be small. If the current setting is holding and the next tool in a three-tool set would be too much, the answer is a slightly firmer board rather than a different one.
- The setting is a number you can write down. Where a person is today is recorded rather than remembered, which means the next session starts from the documented point instead of the practitioner's recollection of it.
What we are not claiming: that this prevents falls, shortens recovery, or improves anyone's balance by some percentage. There is no published protocol or practitioner study on this board yet, and we would rather say so than imply otherwise. The claim is about the mechanism — the range is continuous and the setting is repeatable — and that is a claim you can check yourself in about thirty seconds of standing on it.
Where this goes
The part we are genuinely still working out is what the progression should be — what a sensible sequence of settings looks like for a given starting point, and how quickly it should move. What exists today is drawn from Karen's own coaching notes across a couple of decades of classes, which makes it experience rather than evidence.
If you work with this population and you think a sequence is wrong, we want to hear it. That is most of the reason this blog exists.
