Looking better and working better are different achievements

A great deal of rehabilitation quietly aims at making a body move the way an unaffected body moves. That target sounds obviously correct and frequently is not, because a compensation is usually a solution, not a fault. And removing it without replacing what it was doing costs more than it returns. Six versions of this mistake, checked.

Written by Heath, who has lived it: casts from birth, a fusion at sixteen, the US Army, and distance running.

Checked

Normalization, examined

“If I walked normally, everything would improve.” What the gait is doing

The gait is the workaround, not the problem

An altered walking pattern is generally the most efficient solution available to a body with a specific limitation. Deliberately walking “normally” means overriding that solution while the limitation stays exactly where it was.

The predictable result is more effort, more load on structures that were already covering for something, and often more pain instead of less. If you want the gait to change, change what is driving it (range, strength, footwear) and let the pattern follow.

“Symmetry is the goal.” Why it usually is not

Symmetry between unequal legs is a cost

Wearable devices have made asymmetry visible to everybody and produced a great deal of unnecessary anxiety with it. If one leg has less capacity than the other, an asymmetric pattern is the body distributing work sensibly.

Forcing symmetry moves load toward the side that is already short of capacity. The productive targets are strength, tolerance and recovery. And when those improve, asymmetry often reduces on its own without ever having been aimed at.

“Compensation is bad and should be corrected.” A more useful distinction

Depends entirely on whether it is affordable

Compensation is how bodies work. The question is never whether you are compensating but whether the structure doing the compensating can afford it indefinitely. A hip taking extra work and coping is a good arrangement. A hip taking extra work and hurting every evening is not.

That reframing changes what you measure. Instead of asking whether the movement looks right, ask what it costs and whether the cost is being paid comfortably. Pain, fatigue and recovery time answer that; a video of your gait does not.

“My physiotherapy is not working because I still limp.” Measuring the wrong thing

The limp may be the wrong outcome measure

If you walk further, hurt less, recover faster and do more, the intervention worked, whether or not the limp changed. Where a limp is driven by fixed structure, not by weakness, no amount of good rehabilitation will remove it, and that is not a failure.

Agree the outcome measures at the start. Distance, pain, recovery time and what you can actually do are the ones worth tracking. Appearance is the one that gets tracked by default and means least.

“Adapting means giving up.” What adaptation actually involves

It is the more demanding option

Adaptation means building the strength and tolerance that make a workaround sustainable, choosing footwear that reduces the demand, managing load so recovery keeps up, and getting on with what you want to do. None of that is passive and none of it is resignation.

Normalization, by contrast, often means years of effort aimed at a target that was never reachable, ending in the conclusion that the body failed. Adaptation aims at what can change and generally produces more capability, not less.

“So I should just accept everything as it is.” Where the line actually sits

No. Accept the structure, not the symptoms

This page argues against chasing normal appearance. It does not argue for accepting pain, for leaving weakness untrained, or for assuming nothing can improve. Plenty is genuinely modifiable: strength above the affected part, load tolerance, recovery capacity, footwear, and how a week is structured.

The distinction is between what is fixed and what is trainable. Fixed structure is worth designing around. Weakness, deconditioning and bad footwear are worth attacking. Confusing the two in either direction is where people lose years.

Two targets, side by side

Normalization aims atMovement that looks typical. Symmetry. A gait that matches a textbook.

Adaptation aims atDoing more, for longer, at lower cost, with recovery that keeps pace.

The tellOne is measured by how you look. The other by what you did last week and how you felt on Thursday.

Occasionally the two point the same way, and where a movement pattern is genuinely inefficient and not protective, tidying it up helps. The mistake is assuming they always coincide, and treating any departure from typical movement as something to be eliminated regardless of what it was accomplishing.

Ask what it costs, not what it looks like. The body is answering a question about load, not about appearance.

Where I landed on this

I spent a long time trying to run more symmetrically, which achieved nothing except making running harder and more uncomfortable. What actually changed my running was hip and glute strength, shoes with a rocker, and paying attention to recovery rather than to pace.

My stride is still visibly asymmetric. I also run considerably further than I did when I was trying to fix it, on a fused hindfoot, with less trouble afterwards. That is the whole argument on this page, and it took me an embarrassingly long time to work out.

Adaptation and normalization

What is the difference between adaptation and normalization?

Normalization aims at movement that looks typical; adaptation aims at doing more, for longer, at lower cost. One is measured by appearance, the other by what you managed last week and how you felt afterwards.

Should I try to walk more normally?

Usually not directly. An altered gait is generally the most efficient solution available to a body with a limitation, so overriding it adds effort and load without removing the limitation. Change what drives it instead and let the pattern follow.

Is compensation harmful?

Not inherently. Compensation is how bodies work. The useful question is whether the structure doing the compensating can afford it indefinitely, which pain, fatigue and recovery time answer far better than a gait video.

Is chasing symmetry worth it?

Rarely between legs of unequal capacity, since forcing symmetry moves load toward the side already short of it. Strength, tolerance and recovery are the productive targets, and asymmetry often reduces on its own when they improve.

Does my physiotherapy work if I still limp?

If you walk further, hurt less and recover faster, it worked. Where a limp is driven by fixed structure, not weakness, no rehabilitation will remove it, and appearance is a poor outcome measure to have chosen.

Does adaptation mean accepting pain?

No. It means accepting fixed structure while actively attacking what is modifiable: strength, load tolerance, recovery capacity and footwear. Confusing fixed with trainable, in either direction, is where people lose years.
