The Stair Shuffle: How Good Rehab Advice Becomes a Bad Habit
There are few rehabilitation instructions that have survived as long—or escaped as much scrutiny—as this one:
"Up with the good, down with the bad."
Every physical therapist has said it.
Every patient remembers it.
Almost nobody remembers to tell patients when to stop doing it.
Knee replacement.
Hip replacement.
Ankle fracture.
ACL reconstruction.
Achilles repair.
Yep.
It's practically printed on every discharge packet in America.
The problem isn't that it's wrong.
The problem is that almost nobody explains why you're doing it, when you're supposed to stop doing it, or what happens if you never do.
Like many things in rehabilitation, a temporary strategy quietly becomes a permanent habit.
That's the Stair Shuffle.
Where the Rule Comes From
The saying actually has a sound biomechanical basis.
Walking upstairs requires your leg to generate enough force to lift your entire body. Your quadriceps, gluteus maximus, and calf muscles all have to work together to propel you upward.
If one leg is painful, weak, or healing, it makes sense to lead with the stronger leg.
Going downstairs is even more demanding.
Descending stairs isn't primarily a strength exercise—it's an exercise in force absorption. (Andriacchi et al., 1980; Costigan et al., 2002).
Your quadriceps eccentrically control knee flexion.
Your glutes control the hip.
Your calf controls the ankle.
Your balance system has to coordinate everything while gravity tries to accelerate you toward the floor.
If the injured leg can't absorb force yet, letting the healthy leg control your body's descent is simply safer.
So yes...
"Up with the good, down with the bad" is good advice.
At least...
For a while.
The problem isn't teaching the cue. The problem is forgetting to take it away.
Here's Where Patients (and Sometimes Therapists) Get Confused
One of the biggest misconceptions happens after hip and knee replacements.
Most modern joint replacement patients leave the hospital weight bearing as tolerated (WBAT). (Jette et al., 2020).
That means exactly what it sounds like.
They're allowed—indeed encouraged—to put weight through the surgical leg almost immediately. (Jette et al., 2020; Castrodad et al., 2019).
Yet many patients hear:
"Up with the good, down with the bad."
And somehow interpret that as:
"Don't use your new knee."
Those are two completely different instructions.
The implant usually isn't the limiting factor.
Pain, swelling, muscle inhibition, weakness, balance, and confidence are. (Rice & McNair, 2010).
Immediately after surgery, patients often have:
Pain
Swelling
Quadriceps inhibition
Glute weakness
Poor balance
Reduced confidence
A patient may be perfectly safe standing on their new knee while brushing their teeth.
That doesn't mean they're ready to control a slow, smooth descent down twelve stairs.
Those are two very different physical tasks.
In fact, descending stairs can generate forces several times body weight while demanding excellent eccentric quadriceps control—something that's commonly impaired during the early stages of recovery. (Andriacchi et al., 1980; Costigan et al., 2002).
The restriction isn't because the implant is fragile.
It's because the muscles aren't yet capable of doing their job. Pain, swelling, and arthrogenic muscle inhibition temporarily reduce strength and motor control.
That's what the stair cue is protecting—not the implant itself.
Current research doesn't support babying patients after joint replacement. It supports progressively challenging them. Modern clinical practice guidelines emphasize early weight-bearing, progressive strengthening, gait training, and functional practice after total knee arthroplasty (Jette et al., 2020). The question isn't whether patients should use the leg. The question is when they're ready to stop compensating.
The Problem Isn't the Cue.
The Problem Is That Nobody Tells Patients When It Expires.
I've met patients months after surgery.
Even several years later.
Still climbing stairs one step at a time.
Not because they're in pain.
Not because they're weak.
Not because their new knee can't do it.
Simply because...
"That's how I was taught."
Nobody ever said,
"Okay, you've earned the right to stop doing that."
Instead, the compensation became the movement pattern.
Rehab Loves Teaching Compensations...
...and sometimes forgets to remove them.
Think about all the instructions patients receive:
Up with the good, down with the bad.
Keep the brace locked.
Don't kneel.
Don't squat.
Don't let your knees go over your toes.
Brace your core before every movement.
Never bend your back.
Some of those instructions have value.
For a while.
The problem is they rarely come with an expiration date.
Compensations are tools.
They are not destinations.
The goal of rehabilitation isn't to become really good at compensating.
It's to make the compensation unnecessary.
We wouldn't expect someone to use crutches forever because they once broke an ankle.
We shouldn't expect them to climb stairs one step at a time forever because they once had a knee replacement.
So When Should Patients Stop?
The answer isn't based on the calendar.
It's based on function.
Patients should begin transitioning back to a normal reciprocal stair pattern when they can:
Step up without significant pain.
Control stair descent without collapsing or dropping.
Demonstrate adequate balance.
Perform repeated step-ups without excessive fatigue.
Walk confidently without relying heavily on the handrail.
Or, as I like to tell my patients:
"When it doesn't look scary anymore."
That doesn't mean sprinting up the stairs on day one.
It also doesn't mean refusing to let someone practice reciprocal stair climbing until it looks perfect.
Rehabilitation isn't an all-or-nothing process.
It's a progression.
Current rehabilitation guidelines emphasize progressive strengthening, gait training, functional task practice, and advancement according to clinical milestones rather than arbitrary timelines (Jette et al., 2020; Castrodad et al., 2019).
In my own practice, I have most total hip and total knee replacement patients practicing reciprocal stair gait—on most of the staircase—by the second postoperative week.
Is that aggressive?
Maybe.
Is it reckless?
Not if the patient is ready.
But most patients are surprised by how capable they already are.
More importantly, it builds confidence.
I'm not asking them to throw away the handrail or race upstairs.
I guard them closely, encourage them to use the railing, and remind them that if it doesn't feel safe at home, they shouldn't do it there yet.
No big deal.
We'll practice together until it does.
Sometimes the biggest barrier isn't strength.
It's fear.
And the only way to build confidence is to safely experience success.
The Clinical Reality
One of the biggest jobs of physical therapy isn't teaching compensations.
It's knowing when to stop using them.
Too often we teach patients how to avoid movement instead of helping them earn it back.
The irony is that many knee replacement patients are told they're weight bearing as tolerated on Monday, taught "up with the good, down with the bad" on Tuesday, and then continue that pattern in therapy and at home because no one ever tells them differently.
The implant was never the problem.
Pain, weakness, balance, and muscle inhibition were.
And once those improve...
The cue should improve too.
Every rehabilitation cue should come with an expiration date.
We spend a lot of time teaching patients how to move around an impairment.
We should spend just as much time teaching them when they no longer have to.
Otherwise, yesterday's compensation becomes tomorrow's disability.
The best rehabilitation isn't measured by how well someone compensates.
It's measured by how little they have to.
Otherwise...
Yesterday's compensation becomes tomorrow's disability.
