Most people think crutches are simple—adjust them, stand up, and go.

But improper crutch fit is one of the most common reasons patients develop shoulder pain, wrist strain, nerve irritation, and even falls during recovery.

In physical therapy, correct crutch fitting is step one—because if the fit is wrong, everything that follows is compromised.

Why Proper Crutch Fit Is Critical

When crutches are adjusted incorrectly:

• Too high → pressure in the armpit can compress nerves
• Too low → poor posture and instability
• Handles too high or low → wrist, elbow, and shoulder strain

Rehabilitation standards from organizations like the American Physical Therapy Association emphasize that fit directly impacts safety, comfort, and recovery outcomes.

Done right, crutches:

• Improve balance
• Reduce fall risk
• Protect healing tissues
• Minimize upper body strain

Step 1: Set the Correct Crutch Height

Stand upright with your shoes on and place the crutches under your arms.

What you’re looking for:

• The top of each crutch should sit 1–2 inches below your armpit
• You should be able to fit 2–3 fingers between your armpit and the crutch pad
• Your shoulders stay relaxed—not elevated

Why this matters:
Too much pressure in the armpit can compress nerves and blood vessels, leading to numbness, tingling, or weakness. Proper spacing keeps weight where it belongs—through your hands.

Step 2: Adjust the Handgrips

Let your arms hang naturally at your sides while standing.

Proper handgrip position:

• Handles align with your wrist crease
• When holding them, your elbows bend slightly (15–30 degrees)

Why this matters:

• Too high → shoulder fatigue and reduced control
• Too low → instability and excessive leaning

This slight bend allows for efficient force transfer and better balance.

Step 3: Quick Self-Check

Before you start walking, do a quick check:

• ✔️ No pressure in your armpits
• ✔️ Weight supported through your hands
• ✔️ Upright posture (no slouching)
• ✔️ Comfortable, controlled stance

If something feels off, it probably is—make small adjustments.

The Most Common Mistake

The biggest mistake patients make is resting their weight through the armpits instead of their hands.

This usually comes down to poor fit.

Correct the fit, and you correct the problem.

Final Thought

Crutches aren’t just equipment—they’re part of your recovery.

When they’re fitted correctly, they:

• Support healing
• Reduce strain
• Improve safety and confidence

Take a few extra minutes to get the fit right. It’s one of the highest-impact things you can do for a smoother recovery.
