Question & Answer Series: Specific Products and Fit Part 2

Part 4 in our series Wheelchair Seating and Positioning Misconceptions in Wound Care: Q & A's where Lindsey Sharpe PT, DPT answers questions asked by participants of the webinar by the same name. This week we're focusing on questions about specific products and proper fit. See Part 1, Part 2, and Part 3.


 

12. When are foot “boxes” desired/useful?

When you say “foot boxes”, this can be a very general term! In this section is a complete list of LE supports that can be mounted onto any wheelchair, but what I think you are referring to is the single/double foot support. The single/double foot support would be utilized for someone who possibly has contractures and is unable to be positioned on a standard footplate, someone who is having issues with the LE falling off the footplate, or someone with skin issues on the feet, i.e. diabetic foot ulcers and unable to wear protective shoes or needs offloading on the heels. Both our single and double foot supports have a heel cut-out to eliminate pressure on the heel. 

If someone is having issues on only one side, you can order a single foot support; also, some clients/therapists prefer to use two separate single foot supports even if there are issues on both feet, as it allows swinging away the leg rests for transfers.  The double foot support is for clients who have bilateral issues and who do not need the leg rests to swing away (ie. Lift transfers). The double foot support with the separator would assist in maintaining LE alignment in the chair i.e. preventing ADDuction and IR at the hips/knees to support a more neutral posture and prevent the development of/progression of postural abnormalities. The single and double foot supports can also be used to minimize tone, in some cases, depending on what triggers your client’s tone.

13. The presentation demonstrated varieties of WCs for patients under 300 lbs. What options are available for bariatric members or tall members as the majority of standard WCs do not accommodate our taller patients? 

Great question! Bariatric equipment has its own codes associated; let me provide some examples of what would be the equivalent of the K0004 WC in a bariatric version. 

NOTE: ALL bariatric chairs are going to be much heavier as they must be more durable to withstand to the increased weight capacity. So, these chairs are much more difficult to propel. 

If your bariatric client is unable to functionally propel and be independent in a bariatric manual wheelchair, this is a scenario where sometimes, it is appropriate to bump up to heavy-duty (this is the term for bariatric power chair bases) power chair bases to allow functional independence. Also, often our bariatric clients have heart conditions/respiratory conditions, and I have found that if this is the case, their HRs increase to an unsafe level/O2 stats decrease to an unsafe level when attempting to propel a bariatric manual WC. Again, this is a scenario where it is appropriate to consider a heavy-duty power chair for safety and independence.

 

The two bariatric manual WC codes are:

K0006: Heavy duty WC

These are typically up to 300-350 pound weight capacity, depending on the manufacturer.

 

K0007: Extra heavy-duty WC

These are typically 35-450 weight capacity, depending on the manufacturer.

 

If you would like specific recommendations for a quality heavy-duty or extra heavy-duty Wheelchair for a specific client, please email us at: education@comfortcompany.com

 


 

14. Would you recommend the K0004 for pt who has BLE contractions?

Yes! The goal in wheelchair positioning is always to maximize pressure redistribution and a wheelchair that has adjustability (minimum K0004) can allow this. In addition to an adjustable wheelchair, a patient with LE contractures may need an adjustable cushion. Consider a patient with a hip flexion contracture who is not making any femoral contact with the cushion. Building up the cushion on that side to increase contact will optimize pressure redistribution. Another consideration with LE contractures is LE supports. Let’s look at lower extremity supports in general.

 

LE supports can be added to a chair 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 limb post-surgery on leg rests
  • pair with an external fixator support, providing great stability and support for a LE post hip/knee surgery, or when a LE immobilizer is in use

 

TYPES OF LE SUPPORTS: (see the first question and answer in this post)

Single Foot Support

Double Foot Support

Double Foot Support with Separator

Calf Pads

External Fixator Support

Amputee Support

 

You have all of these options as well as noting that this MAY be a scenario where elevating AND articulating leg rests could be appropriate. See Question 10 for an answer regarding this topic.

  


 

Next week we'll look at the last part in our series: wheelchair configuration questions.
