Drive performance (Speed, range, incline, curb climbing)
Performance variables may show a difference between ruggedness and durability of the
different bases. Do not let these variables rule your decision, but it is recommended to
have a look at them.
What is the maximum speed of the chair? Keep in mind that most chairs are
programmable, so you can start slower than speed up as your child becomes
proficient. Also remember that even the “slower” power chairs typically offer a
top speed (4-5 m/h) that is already higher than a typical walking speed.
Range: how many miles can the chair run between charges?
Incline: What degree of ramp/other incline can the chair mount?
How many inches of obstacle can it climb?
Also keep in mind that some companies specify their tested, recommended, safe
results, others might market their maximum abilities. It is always a good idea to
try the chair in different settings to assess it for yourself (on ramps, through door
thresholds, in grass, etc.)
Suspension
Suspension is not available in all chairs, nor is it always needed, however, it has many
benefits, especially at higher speeds. It enables a smoother ride, which improves comfort
and helps maintain position, which can be important for users with limited trunk control
and strength. A smooth ride can help maintain head position for users with weak neck
musculature, and can also reduce the risk of developing pressure sores. A suspension may
be important especially for larger children, and with heavier outdoors use.
Growth
Due to insurance reimbursement, any wheelchair will typically have to last about 5 years,
so make sure the system offers enough growth to last that time frame.
Programming/electronics
Can the wheelchair accept alternative controls? What can be programmed (speed,
torque/power, joystick throw, etc.) If you are savvy with electronics, you could consider
getting a programmer so you can make changes at home as your child progresses in
driving.
Warranty/reputation
What is warranteed, and for how many years? Check out some online chatgroups and
associations to receive information from others on different manufacturers and models.
