Knowledge of wheelchair selection and use

Guided Reading

In the process of treating patients, the wheelchair is a very widely used tool, such as lower limb disability, hemiplegia, paraplegia below the chest and mobility disabilities are very suitable. As a rehabilitation therapist, it is very necessary to know the characteristics of wheelchair, choose the most suitable wheelchair and the most correct use method. 

Do you have a thorough understanding of wheelchair selection and use?

If a patient or family member asks you how to choose and use a wheelchair, can you give a reasonable prescription for a wheelchair?

 

First of all, what kind of damage can an unsuitable wheelchair do to the user?

Local compression is too great

Bad posture

To induce scoliosis

Causing joint contractures

What are the unsuitable wheelchairs: the seats are too shallow and not high enough; the seats are too wide and not high enough

The major stress areas of wheelchair users were the ischium tubercle, thigh, carmine and scapular region. Therefore, in the choice of wheelchair to pay attention to these parts size is appropriate to avoid skin wear, abrasions and pressure sores.

 

The choice of wheelchair, this is the most basic knowledge of rehabilitation therapists, must be kept in mind!

The choice of a regular wheelchair

Seat width

Measure the distance between your hips or strands when you sit. Add 5 cm to the distance, leaving 2.5 cm on each side. The seat is too narrow, up and down the wheelchair is more difficult, hip and thigh tissue is compressed; the seat is too wide, not easy to sit down, wheelchair manipulation is not convenient, both upper limbs easy fatigue, in and out of the door is also difficult.

Seat length

The horizontal distance between the buttocks and the calf gastrocnemius muscles was measured after sitting, and the measurement was reduced by 6.5 cm. The seat is too short, the weight mainly falls on the sitting bone, the local easy to be pressed too much; the seat is too long will press the Rouge pit department, affects the local blood circulation, and easy to stimulate the skin of this department, to the thigh is extremely short or the hip knee flexion contracture patient, then uses the short seat is better.

Seat height

Measure the distance from heel (or heel) to carmine when sitting. Add another 4cm and place the pedal at least 5cm off the floor. The seat is too high for the wheelchair to enter the table; the seat is too low for the sitting bones to bear too much weight.

Seat Cushion

For comfort and prevention of pressure sore, seat cushion should be placed, available foam rubber (5 ~ 10cm thick) or gel cushion. A piece of plywood 0.6 cm thick can be placed under the seat cushion to prevent the seat from sinking.

Backrest height

The higher and more stable the backrest, the lower the backrest, the greater the range of motion of the upper body and upper limbs. A low backrest measures the distance from the seat surface to the armpit (one or both arms are stretched forward and flat) , subtracting 10 cm from the result. High back: measure the actual height of the seat from the face to the shoulders or back.

Handrail height

Sit with your upper arm vertical and your forearm flat on the armrest. measure the height of the chair to the lower edge of your forearm, plus 2.5 cm. Proper armrest height helps maintain correct body posture and balance, and allows the upper limbs to be placed in a comfortable position. The armrest is too high, the upper arm is forced up to lift, easy to feel tired. Armrest is too low, need upper body to lean forward to maintain balance, not only easy fatigue, may also affect breathing.

Other accessories for wheelchairs
