Stairs on crutches come down to one simple rule: your good leg leads going up, your injured leg leads going down. The classic memory aid is “up with the good, down with the bad.” Once you internalize that pattern, the rest is technique and safety details.
Going Up Stairs With a Handrail
A handrail makes stairs significantly easier and safer. Stand close to the bottom step, grip the rail with one hand, and hold both crutches together in your other hand. Some people find it easiest to cross the crutches so they stay compact. Hold your injured leg slightly behind you so it stays clear of the steps.
Push down on the rail and crutches, then step up onto the first step with your good leg only. Your strong leg does all the lifting work here. Once you’re stable on that step, bring the crutches up to meet you on the same step. Repeat this one step at a time. Don’t rush, and don’t try to skip steps.
Going Down Stairs With a Handrail
Going down reverses the order. Stand at the top of the stairs, hold the rail with one hand and both crutches in the other. This time, hold your injured leg out in front of you so it doesn’t accidentally contact the step below.
Place the crutch tip on the middle of the step below you. Shift your weight onto the crutch and the rail together, then gently lower your good leg down to that same step. You’re essentially using your arms and the rail to control a slow, steady descent. Lower yourself one step at a time, and make sure the crutch tip is firmly planted before you commit your weight.
Stairs Without a Handrail
No railing means you keep one crutch under each arm instead of bundling them together. Going up, move your injured leg and both crutches forward together as a single unit, then let your strong leg push you up to the next step. Going down, place both crutches on the step below first, shift your weight onto them, then step down with your good leg.
This takes considerably more arm strength and balance than the handrail method. If the stairs are steep, slippery, or if you feel unsteady, a safer alternative is to sit down and scoot. Hold both crutches in one hand, lower yourself to a seated position, and use your arms to lift or slide yourself up or down one step at a time. It’s slower, but it eliminates fall risk almost entirely.
Non-Weight-Bearing vs. Partial Weight-Bearing
If your doctor has told you to keep all weight off your injured leg, the technique above applies exactly as described. Your injured foot never touches a step. All your weight goes through your arms, the crutches, and your good leg. Keep your bad leg behind you when going up and in front of you when going down so it stays out of the way.
If you’re allowed partial weight-bearing, you have a bit more flexibility. You can lightly place your injured foot on each step for balance as long as you’re not loading it beyond what your doctor or physical therapist has approved. The movement sequence stays the same: good leg leads up, injured leg leads down. The difference is that partial weight-bearing gives you a wider base of support on each step, which feels more stable. When in doubt about how much weight you’re allowed to put through your injured leg, stick with the non-weight-bearing technique until you’ve confirmed with your care team.
Safety Checks Before You Start
Check your crutch tips before tackling stairs. The rubber feet on the bottom of crutches wear down over time, and worn tips lose traction. Look at the tread pattern on the rubber. If it’s smooth or cracked, replace the tips. They’re inexpensive and available at most pharmacies.
Wet crutch tips on indoor floors are especially dangerous. If you’ve been outside in rain or snow, dry the tips before stepping onto tile, hardwood, or linoleum. On outdoor stairs, watch for leaves, ice, and wet surfaces. Rubber-tipped crutches generally grip wet pavement fine, but anything slick on top of the surface (moss, ice, wet leaves) changes the equation.
A few other practical points: wear shoes with good grip rather than socks or slippers, clear anything off the stairs that could catch a crutch tip, and make sure the stairway is well lit. If you’re navigating stairs for the first time after surgery or an injury, have someone stand nearby. They should position themselves below you when you’re going up (to catch you if you fall backward) and above you when you’re going down (to catch you if you fall forward).
Building Confidence on Flat Ground First
Stairs demand more upper body strength and coordination than walking on level ground. Before attempting them, you should feel comfortable and stable using your crutches on a flat surface, including starting, stopping, and turning. Practice shifting your full body weight through your arms and onto the crutches so the motion feels natural rather than forced. If your arms fatigue quickly on flat ground, stairs will be significantly harder and less safe.
A single step, like a curb or a front door threshold, is a good intermediate challenge. Use the same “good leg up, bad leg down” pattern on that single step until it feels automatic. Once you can manage one step without hesitation, a full staircase is just repetition of the same movement.
