Using underarm crutches the right way can make recovery safer, faster, and far more comfortable. Whether you are recovering from surgery, a fracture, a sports injury, or temporary mobility limitations, learning how to fit underarm crutches properly is essential. Poorly adjusted crutches may cause shoulder pain, wrist strain, poor posture, nerve compression, and even falls.
This guide explains how to fit underarm crutches step by step while following Google EEAT principles by providing accurate, experience-based, trustworthy, and practical information.
Why Proper Underarm Crutches Fitting Matters
Many people assume crutches are “one size fits all,” but incorrect sizing is one of the most common causes of discomfort and instability. Properly fitted underarm crutches help distribute body weight safely through the hands and arms instead of placing excessive pressure on the armpits.
Correct fitting can help:
Improve balance and walking stability
Reduce pressure on shoulders and nerves
Prevent wrist fatigue and muscle strain
Support safer rehabilitation
Increase confidence during movement
Healthcare professionals often recommend checking crutch sizing before first use and adjusting them again if shoes or walking surfaces change.
What Are Underarm Crutches?
Underarm crutches, also called axillary crutches, are mobility aids designed to assist people who cannot fully bear weight on one or both legs.
They typically include:
- An underarm pad
- Handgrips
- Adjustable height settings
- Non-slip rubber tips
These crutches are commonly used after:
- Foot surgery
- Ankle sprains
- Leg fractures
- Knee injuries
- Hip procedures
Compared with forearm crutches, underarm crutches are often easier for beginners because they provide broader upper-body support.
How to Measure the Correct Height for Underarm Crutches
The first step in learning how to fit underarm crutches is adjusting the overall height.
Step 1: Wear Your Normal Walking Shoes
Always measure while wearing the shoes you expect to use most often. Shoe height affects crutch positioning and walking posture.
Step 2: Stand Upright Naturally
Stand straight with your shoulders relaxed. Place the crutch tips about 6 inches to the side of your feet and slightly forward for stability.
Step 3: Check the Underarm Gap
The top of the crutches should sit approximately 1.5 to 2 inches below the armpits.
This small gap is extremely important because resting directly on the underarm pads may compress nerves and blood vessels. Long-term pressure can even lead to numbness or tingling in the arms.
Step 4: Adjust the Handgrips
When holding the handgrips:
Your elbows should bend slightly
Aim for about 15–30 degrees of elbow flexion
Your wrists should align naturally with the grips
Most body weight should be supported through your hands, not your armpits.
Common Mistakes When Fitting Underarm Crutches
Even high-quality underarm crutches can become uncomfortable if adjusted incorrectly.
Crutches That Are Too Tall
Overly tall crutches can force the shoulders upward and increase pressure under the arms. This may cause:
Shoulder fatigue
Neck pain
Poor balance
Nerve irritation
Crutches That Are Too Short
Short crutches may cause users to lean forward excessively, creating poor posture and instability during walking.
Incorrect Handgrip Position
If the handgrips are too low or too high, wrist strain can occur quickly. Improper grip positioning may also reduce weight distribution efficiency.
Leaning on the Armpits
One of the biggest mistakes is placing full body weight onto the underarm pads. Proper crutch walking should rely mainly on arm and hand strength.
How to Walk Safely with Underarm Crutches
After fitting the crutches correctly, safe movement techniques are equally important.
Walking on Flat Surfaces
For non-weight-bearing movement:
- Move both crutches forward together
- Shift weight onto the handgrips
- Swing the injured leg forward without touching the ground
- Step through with the healthy leg
Move slowly and maintain steady balance.
Using Stairs
Stairs require extra caution.
A common rehabilitation guideline is:
- “Up with the good”
- “Down with the bad”
When climbing stairs:
- Step up first with the stronger leg
- Then move the injured leg and crutches together
When descending:
- Place crutches down first
- Move the injured leg
- Then bring down the stronger leg
Whenever available, use handrails for added stability.
Tips to Improve Comfort While Using Underarm Crutches
Proper fitting is only part of long-term comfort. These additional tips can improve the user experience significantly.
Use Padded Accessories
Extra padding on handgrips or underarm supports may reduce pressure during extended use.
Check Rubber Tips Regularly
Worn rubber tips can become slippery and dangerous. Replace them if the tread becomes smooth or cracked.
Maintain Good Posture
Keep your back straight and avoid leaning excessively forward. Proper posture improves balance and reduces fatigue.
Take Breaks During Long Use
Extended crutch use can tire the shoulders, arms, and hands. Rest periodically when possible.
Choosing High-Quality Underarm Crutches
Not all underarm crutches offer the same level of safety and durability. When selecting crutches, consider:
- Lightweight aluminum construction
- Adjustable height ranges
- Non-slip rubber feet
- Ergonomic handgrips
- Durable underarm cushioning
- High weight capacity
Professional medical mobility equipment suppliers often provide multiple sizing options for adults and children to ensure proper fitting.
How to Know If Your Underarm Crutches Are Fitted Correctly
Well-fitted underarm crutches should feel stable, balanced, and comfortable during normal movement.
Signs of proper fit include:
- No direct pressure in the armpits
- Slight bend in the elbows
- Comfortable hand positioning
- Upright posture while walking
- Stable balance during movement
If you experience numbness, severe shoulder pain, wrist discomfort, or instability, recheck the adjustments or consult a healthcare professional.
FAQs About How to Fit Underarm Crutches
How far below the armpit should underarm crutches be?
Underarm crutches should sit about 1.5 to 2 inches below the armpits to avoid nerve compression and improve comfort.
Should body weight rest on the armpits?
No. Body weight should mainly be supported by the hands and arms through the handgrips, not the underarms.
How much should elbows bend when using underarm crutches?
Most experts recommend a slight elbow bend of approximately 15–30 degrees for proper control and comfort.
Can underarm crutches cause nerve damage?
Yes. Improper use or excessive pressure under the arms can compress nerves and cause numbness or tingling, sometimes called crutch palsy.
Are adjustable underarm crutches better?
Adjustable underarm crutches are generally preferred because they allow customized fitting for different heights and walking conditions.
Conclusion
Learning how to fit underarm crutches correctly is essential for safe recovery, injury prevention, and comfortable mobility. Proper adjustment reduces pressure on the body, improves walking stability, and helps users regain independence more confidently.
Whether using underarm crutches temporarily after surgery or during longer rehabilitation periods, correct sizing and walking technique can make a major difference in daily comfort and safety.
