Ergonomic Crutches: What Actually Causes Armpit and Wrist Pain, and What to Look For

If the crutches you were given have started to hurt, check where your weight is going before you replace them. Cleveland Clinic's guide on how to use crutches explains that you should rest your weight on the handgrips instead of the tops of the crutches, since leaning on your armpits can hurt your shoulders and the nerves and blood vessels under your arms. If the fit is right and it still hurts, the design is the next thing to look at.

This guide covers what causes crutch pain, which design details change it, and what to check before you buy.

Why Standard Underarm Crutches Start to Hurt

A crutch is a load-transfer device. The National Library of Medicine's clinical reference describes crutches as devices that transfer body weight from the legs to the torso and arms, and on a basic aluminum pair, that happens at two points.

The first is the foam pad at the top. Pressure is divided by contact area, so a narrow pad drives the same force through the same patch of tissue every step. The second is the handgrip, which sits square to the shaft and holds your wrist bent back under load. Its narrow circumference concentrates that load into a small part of the hand.

What Separates a Genuinely Ergonomic Pair From a Standard One

The obvious fix is more foam, but it’s not always the right call. The same clinical reference notes that manufacturers have added softer padding to the underarm pad. While softer underarm pads can improve cushioning, they can also affect fit. That’s why the design of the cushion, including how it compresses and conforms to the user, matters just as much as the thickness.

"Traditional crutch pads are fairly hard and don't conform very well to the body," said Max Younger, Senior Director of Industrial Design and Innovation at Drive Medical. "As you walk, the crutch sits between your rib cage and inner arm, where it can rub and create pressure and bruising. We wanted the pad to squish and move with the user, conforming to their individual shape."

The comparison against a standard crutch pad is the figure worth looking for. The MD by Drive Air-Crutch features patented Airgonomic™ cushions built from a layered air bladder and PU foam, measuring 57.9% thicker top to bottom than a standard crutch pad, with 21% more contact surface. That thickness is what gives the pad room to compress, so the air bladder and foam flex and conform to your body shape instead of sitting against you like a block.

The Handgrip Angle and the Tip Matter as Much as the Padding

The natural angle for gripping a handle isn’t 90 degrees to your forearm. If you close your palm tightly around a tube and look at the inside of your hand, you’ll see that the line of your grip sits at roughly 9 degrees, not perpendicular to your forearm. A handle set at 90 degrees to the shaft pulls the wrist out of that line and holds it there under load, which creates a pressure pinch point above the thumb.

"Traditional crutch handles are basically 90 degrees to the crutch, and that puts the wrist into a fairly harsh angle," Younger noted. "That becomes a big deal when you are non-weight-bearing and essentially walking on your hands every other step."

Handgrip height is the part you already control, and the National Library of Medicine's clinical guidance is to set it so your elbow has 30 degrees of flexion, meaning a slight bend rather than a straight arm. A natural wrist angle sits just about 9 degrees off perpendicular, and the Air-Crutch angles its GelTech handles to match. Its wider grip spreads the load across more of the palm, and Drive Medical measures up to 27.6% less pressure at the handle than a traditional crutch.

At the ground, the Flex Grip™ Air Tip pairs a firm center section with flexible outer edges, and a donut-shaped air bladder controls how much those edges give, so the bottom of the tip conforms to uneven ground while the center stays stable. Its tread uses a dot pattern with traction nubs to push water outward, while closed rings, common on standard tips, can trap water underneath.

Five Things to Check Before You Buy a Pair of Ergonomic Crutches

The difference comes down to five features:

  1. Underarm pad construction. Compare the pad against a standard crutch pad on two counts: how much thicker it is top to bottom, which is what gives it room to compress and conform to you, and how much contact surface it has.
  2. Handgrip angle. A grip angled toward the natural grip position of the hand does more over a long recovery than softer foam on a straight one.
  3. Published figures that name their comparison. A number only helps you if you can see what it was measured against. For the underarm pad, Drive Medical lists 21% more surface area and 57.9% thicker padding than a standard crutch pad. At the hand, it lists up to 27.6% less pressure through the hand and wrist compared to a traditional crutch.
  4. Fit range and weight capacity. A crutch at the edge of its range never fits well. The Air-Crutch adjusts from 4 feet 7 inches to 6 feet 7 inches, can support up to 300 pounds and weighs 4.8 pounds for the pair.
  5. What happens after the sale. Check the warranty terms and whether you can reach someone who knows the product when you need help. The Air-Crutch is $99 on Drive Medical at Home, with a limited lifetime warranty.

Who Designed the Air-Crutch, and Why That Shows Up in the Product

Max Younger invented his first crutch for his father, and that crutch later grew into a company.

"Growing up, I watched my dad use crutches through years of knee problems, surgeries and knee replacements," said Younger. "In 2008, he lost his leg after contracting a staph infection during a knee surgery. At that point crutches were no longer something he would just use during recovery. They were going to be part of his everyday life."

Younger co-founded Mobility Designed in 2014, and its first product, the M+D Comfort Crutch, was named a finalist in Fast Company's Innovation by Design Awards. Drive Medical acquired Mobility Designed's portfolio of products in June 2024, bringing co-founder Younger with it, so the line could reach more people across a wider range of products.

That difference, between a device someone uses through a recovery and one they depend on every day, is what Younger designs around. The M+D Comfort Crutch approached it by rethinking the crutch from scratch. The Air-Crutch takes the opposite route, keeping the familiar underarm format that patients already know and clinicians already know how to fit, and rebuilding the contact points that cause the pain of traditional crutches.

When the Fit Is Right and It Still Hurts

A standard aluminum crutch from urgent care is built to be adjustable and available that day. It is not built for daily use over a long recovery, so a narrow underarm pad and a straight handgrip start to show within a few weeks. If the fit is right and the pain continues, the design has reached its limit, and a wider pad and angled handgrip are worth the upgrade.

Frequently Asked Questions

What are ergonomic crutches and how are they different from regular crutches?

Ergonomic crutches change how your body weight is distributed rather than what the frame is made of. The differences that matter are a wider, better-cushioned underarm pad and a handgrip angled toward the natural resting position of the wrist. A standard aluminum crutch typically does not include these features.

Why do crutches hurt your armpits?

Because a narrow pad concentrates your body weight into a small patch of soft tissue every step. Pressure is divided by contact area, so the narrower the pad, the more force reaches the tissue beneath it. Cleveland Clinic advises resting your weight on the handgrips, since leaning on your armpits can hurt the nerves and blood vessels underneath. Most people aren’t used to carrying their weight on their hands, so they end up resting on the underarm cushions anyway, which is why the construction of the pad matters.

How do I stop crutches from hurting my armpits?

Start with the fit. The shoulder pad should sit about a palm's width below your armpit with your shoulder relaxed, your weight should rest on the handgrips, and the handgrip should be set so your elbow bends about 30 degrees. Younger describes the motion as squeezing the crutch side to side between your bicep and rib cage rather than resting your weight on the underarm. If soreness continues into a second week, the pad is usually the culprit.

Does adding extra padding to crutch pads help?

It depends on whether the padding is part of the crutch or added on top of it. Adding an extra pad to the top of a standard crutch reduces the space between your armpit and the pad, and the National Library of Medicine's reference on crutches notes that this can lead to what the padding was intended to prevent. A pad engineered from the start to be thicker and to compress under load is a different thing: it gives the air and foam room to flex and conform to your shape instead of eating into the clearance a correct fit depends on.

Why do my hands and wrists go numb when I use crutches?

Numbness in the hand usually traces to the handgrip. A grip set at a right angle to the shaft holds the wrist bent back while it carries your weight, and a study in the Journal of Orthopaedic Research found that wrist extension raises pressure inside the carpal tunnel. Speak with a clinician if numbness persists after you stop using crutches.

What is crutch palsy?

Crutch palsy is a nerve-compression injury linked to bearing weight through the armpit instead of the hands. The National Library of Medicine's reference describes it in underarm crutch users who rest their weight on the shoulder rest, where pressure on the brachial plexus can cause palsy affecting the radial and ulnar nerves. Anyone with numbness, tingling or weakness in the hand should speak to a clinician.

Are the crutches from urgent care good enough?

For a few days, usually yes. Clinic-issued crutches are built to be adjustable, inexpensive and immediately available, and they do that job. What they are not built for is weeks of daily use, which can lead to pain. If you will be on them for more than a few days, compare the underarm pad against a standard one, the handgrip angle and circumference, and the tip at the ground. A non-weight-bearing recovery means using crutches on wet floors, in and out of a shower, where the concentric rings on a standard crutch tip can trap water underneath and hydroplane.

How much do ergonomic crutches cost and what should they include?

Expect to pay more than a basic aluminum pair. The MD by Drive Air-Crutch is $99 on Drive Medical at Home, adjusts from 4 feet 7 inches to 6 feet 7 inches, supports up to 300 pounds, weighs 4.8 pounds for the pair and carries a limited lifetime warranty. Beyond price, look at the pad's surface area and the angle of the handgrip.

Where can you buy the MD by Drive Air-Crutch?

On Drive Medical at Home, the company's own online store for consumers, where it is $99 with a limited lifetime warranty. Because the store is run by the manufacturer, the product page carries the published measurements, the full fit and height ranges and the warranty terms in one place, and the live chat is staffed by specialists who work on this equipment rather than a general catalog. Drive Medical has manufactured home medical equipment since 2000, and the Air-Crutch sits in its wider canes and crutches range.
