Proper leg positioning in a wheelchair is essential for comfort, circulation, pressure sore prevention, and overall mobility. If you or a caregiver are wondering how to adjust wheelchair legs correctly, this step-by-step guide provides clear, safe instructions for modifying leg rests to suit individual needs. Whether you’re dealing with removable, swing-away, or elevating leg rests, knowing how to make precise adjustments can significantly improve daily function and posture. In this guide, we’ll walk you through identifying your leg rest type, making height and angle adjustments, ensuring secure locking, and avoiding common mistakes.
Identify Your Wheelchair Leg Rest Type
Before making any adjustments, it’s crucial to determine the type of leg rest your wheelchair uses. Different models require different methods for adjustment and removal.
How to Tell If You Have Swing-Away Leg Rests
Swing-away leg rests pivot outward from the frame, allowing easier transfers in and out of the chair. Look for a hinge mechanism near the front of the frame. These are common on indoor and transit wheelchairs. To confirm, gently try swinging the leg rest outward—there should be a release lever or button that unlocks the swing function.
Recognizing Elevating Leg Rests
Elevating leg rests can be raised to support the legs above heart level, often used for swelling or circulation issues. They typically feature a telescoping mechanism and a strap or latch to secure the footplate. These are adjusted using a lever or knob and may lock into multiple height positions.
Fixed vs. Removable Leg Rests: What’s the Difference?
Fixed leg rests are permanently attached, while removable ones can be detached completely from the frame. Removable types usually have a quick-release pin or clip. Check near the mounting point for a push-button or pull-pin mechanism—if present, it’s likely removable.
Adjusting Leg Rest Height for Proper Leg Support
Correct leg rest height ensures your knees aren’t elevated too high or hanging too low, which can cause pressure on the thighs or lower back strain.
Step-by-Step: Changing the Vertical Position of Leg Rests
- Sit in the wheelchair with feet flat on the footplates.
- Locate the adjustment pin or lever on the leg rest support tube.
- Press the release button or remove the pin to loosen the mechanism.
- Slide the leg rest up or down to the desired height.
- Reinsert the pin or lock the lever securely.
- Test stability by gently pressing down on the footplate.
Ensure both sides are adjusted evenly to maintain balance.
How to Know If the Leg Height Is Correct
When seated:
– Your thighs should be fully supported without pressure under the knees.
– There should be about one to two fingers’ width between the edge of the seat cushion and the back of the knee.
– Feet should rest flat on the footplate with knees slightly lower than hips.
If you experience numbness, tingling, or redness under the thighs, the leg rests may be too high or too long.
Modifying the Angle of Footplates and Calf Pads
The angle of the footplate affects ankle alignment and calf comfort, especially during prolonged sitting.
Adjusting Footplate Tilt for Better Ankle Position
Some footplates have an angle adjustment feature:
– Loosen the mounting bolts slightly using a hex key.
– Tilt the plate up or down to achieve a 90-degree angle at the ankle.
– Retighten the bolts securely.
– Repeat on the other side for symmetry.
A neutral ankle position helps prevent foot drop and improves circulation.
Re-positioning Calf Pads on Elevating Leg Rests
For users with limited knee flexion or spasticity:
– Loosen the clamp or bracket holding the calf pad.
– Slide or rotate the pad to align with the lower leg.
– Ensure the pad supports the calf without pressing into the back of the knee.
– Tighten the lock mechanism firmly.
Swinging or Removing Leg Rests for Easier Transfers
Proper transfer technique reduces strain and injury risk. Adjusting leg rests before standing is a key step.
How to Swing Away Leg Rests Safely
- Press the release lever located on the inside of the leg rest frame.
- Swing the entire unit outward until it locks in the horizontal or vertical parked position.
- Confirm it’s securely latched before attempting to stand.
- After sitting back down, swing the leg rest back into place and ensure it clicks into the locked position.
Never attempt a transfer with the leg rest partially engaged—it can collapse and cause falls.
Removing Leg Rests Completely: When and How
Useful for tight spaces or vehicle transfers:
1. Locate the quick-release pin or lever.
2. Pull the pin or press the release button.
3. Lift the leg rest straight out of the mounting bracket.
4. Store in a safe place to avoid damage.
Always reattach before moving the wheelchair.
Common Mistakes to Avoid When Adjusting Wheelchair Legs
Even small errors can affect safety and comfort.
Don’t Over-Tighten Adjustment Bolts
Over-tightening can strip threads or damage plastic components. Use hand tools with care and stop when resistance increases suddenly.
Avoid Uneven Adjustments Between Sides
Mismatched heights or angles can lead to pelvic tilt, back pain, or pressure sores. Always double-check both sides after making changes.
Never Use Damaged or Worn Leg Rests
Cracks in the frame, loose footplates, or weak locking mechanisms compromise safety. Replace damaged parts immediately.
Safety Checks After Adjusting Leg Rests
After any modification, perform a quick safety inspection.
How to Test Stability Before Use
- Apply downward pressure on each footplate.
- Gently shake the leg rest to check for wobbling.
- Confirm all pins are fully inserted and levers are locked.
Visual Cues That Indicate Proper Alignment
- Footplates are parallel to the floor.
- Legs rest naturally without outward or inward rotation.
- No gaps between thigh and seat edge.
When to Consult a Healthcare Professional or ATP
While minor adjustments can be made at home, some situations require expert input.
Signs You Need a Seating Assessment
- Persistent discomfort or skin redness
- Changes in leg length or muscle tone
- Difficulty positioning feet comfortably
A certified Assistive Technology Professional (ATP) or physical therapist can perform a full seating evaluation and recommend customized modifications.
Getting Replacement Parts or Upgraded Supports
If standard leg rests don’t meet your needs, consider:
– Extended leg rests for taller users
– Articulating elevating legs for medical conditions
– Carbon fiber lightweight options for active users
Contact your equipment provider or DME supplier for compatible upgrades.
Final Note: Properly adjusted wheelchair leg rests enhance comfort, posture, and independence. Always follow manufacturer instructions and perform regular checks to ensure safety. When in doubt, consult a clinician or mobility specialist.
