Taking a Closer Look at Wheelchair Accessories

Taking a Closer Look at Wheelchair Accessories

Too often in the world of seating and positioning, accessories are used as “band-aids” for a less than optimal wheelchair seating system. Accessories may not be needed if you take your time in selecting the right model and size wheelchair and then select an appropriate cushion and back support. When used the proper way, they can be the finishing touch to achieve the best posture possible for your patient! Below we go over the different types of wheelchair accessories on the market today.


Upper Extremity Supports

Upper extremity (UE) supports can be added onto the existing arm rest to:

  • Add length
  • Add additional postural support
  • Decrease contracture risk
  • Decrease dependent edema in UE
  • Increase comfort while sitting in wheelchair
  • Stabilize a weak UE in an optimal position

Most of us don’t sit with our elbows bent to 90° with the forearm straight out. So why do we position our patients this way, especially when dealing with abnormal tone or decreased range of motion? Choose an upper extremity support that has angle adjustability!!

Types of UE Supports

You can choose a basic non-adjustable support or you can choose a pad and hardware style to suit the needs of your patient.

Hardware Types

  • Slide On: Pad will be aligned with existing arm rest
  • Bolt On: Pad will be aligned with existing arm rest
  • Swing-Away: Pad can move towards or away from body as needed
  • Articulating: Pad can be positioned in any plane; most adjustable option

Pad Types

  • Standard Trough: Helps keep the arm from sliding off the pad
  • Minimal Contour: Low profile support
  • Moldable: Accommodates flexion or extension of the wrist and finger abduction

Lower Extremity Supports

Lower extremity (LE) supports can be added to a wheelchair to:

  • Support the lower leg, foot, and ankle in optimal position
  • Decrease risk of contracture
  • Accommodate for contractures and protect from injury
  • Manage abnormal tone and reflexes
  • Support an amputated limb
  • Support a post surgical limb on the leg rest

Don’t forget that quality leg supports have a range of sizes or can be customized. Consider where you want the support and measure to ensure you get the right fit.


Types of LE Supports

  • Single Foot support
  • Double Foot Support
  • Double Foot Support with Separator
  • Residual Limb Support
  • External Fixator Support
  • Calf Pads

An external fixator support provides great stability and support for a LE post hip/knee surgery, or when a LE immobilizer is in use.


Lateral Trunk Supports

Lateral trunk supports can be added to a wheelchair or back support to:

  • Reduce lateral leaning caused by decreased trunk strength and balance
  • Correct or accommodate for a scoliosis or trunk rotation and prevent further progression of the postural abnormality
  • Decrease pressure points on the apex of the curvature that could possibly lead to skin breakdown and cause pain to the patient

Types of Lateral Supports

  • Mounted: Swing-away or fixed. Attach to the back support with hardware
  • Traditional Foam: Contoured foam pads

If your patient has tone and/or is a heavy leaner, choose mounted lateral trunk supports. Traditional foam supports cannot withstand the sustained pressure, and the foam  will collapse.
